Useful tips on choosing and operating refrigeration equipment

This article is about “Useful Tips on Choosing and Operating Refrigeration Equipment”. If you want to get Best Refrigeration Services in London and Best Refrigeration Repair and Maintenance in London, you should hire Best Air Conditioning Company in London.

To equip a commercial enterprise with high-quality equipment, the main question should be solved - how to choose refrigeration equipment? After all, to understand the diversity of modern refrigeration, which differs in purpose, functionality, elements of performance are very difficult. With the answers to these questions and should begin.

There is no doubt that the main element in the equipment of any commercial enterprise are refrigerated display cases.

Structurally, they are a metal case with a heat-insulating material - polyurethane foam, which has high thermal insulation properties. The sides of the windows are made of impact-resistant plastic. And in the lower part of the equipment is a refrigeration unit, equipped with a hermetic compressor. But some Best Refrigeration Services in London companies providing secure structurally bodies that’s help to Best Refrigeration Repair and Maintenance in London. Get Best Air Conditioning Company in London for the Best Refrigeration Services in London.

In many models of windows with an integrated unit under the display surface there is a convenient camera for storing the stock of goods.

Of course, the composition and color of the equipment have a huge impact on attracting the attention of customers and product presentation. However, first of all, it is necessary to take into account the design features of the device of refrigerated display cases: demonstration area, depth of exposure, type of cooling, method of air circulation in the chamber and much more.

Refrigerators and freezers are widely used in small shops and large self-service stores . In their production, various technical solutions are used: a thermostat - to adjust the temperature in the internal volume, adjustable shelves - to lay out the goods, glass doors that allow a good view of the displayed goods, as well as bright lights.

Cabinets with transparent doors are convenient for trading rooms where demonstration of refrigerated products is necessary, however, cabinets with blind doors for storing inventory are in steady demand. Interior lighting of cabinets contributes to the advantageous presentation of goods, and compliance with the temperature regime is ensured by the use of high-quality polyurethane insulation.

Refrigerators are used by various trade enterprises as well as other high stores. Different Best Air Conditioning Companies in London providing Best Refrigeration Services in London with the Best Refrigeration Repair and Maintenance in London. Their reliability largely depends on the quality of the components used. An important parameter is thermal insulation. The modern method of creating a highly efficient and reliable thermal insulation of refrigeration chambers is the use of polyurethane foam. It is light, characterized by heat resistance, durability and excellent thermal insulation properties.

When buying refrigerators, the following should be taken into account: range of consumption of perishable products, temperature and humidity conditions, product storage periods.

This is the minimum that is worth paying attention to when choosing refrigeration equipment. But often happens differently. Buyers make choices based on the fact that refrigeration equipment has a presentable appearance, imported components and a small price. And do not think at all about the strength of the design, the operation of the compressor, the availability of protection and automation. Reliability issues are not evaluated and go to the background. Then it is very important that the refrigeration part be properly selected for performance, as well as the availability of control and monitoring systems.

Or another problem arises when purchasing low-cost equipment - the cost of servicing equipment turns out to be much higher. While the use of equipment of a higher class, today does not require large maintenance costs. When any problem occurs with your refrigeration you must contact to the Best Air Conditioning Company in London that’s providing Best Refrigeration Services in London as well as Best Refrigeration Repair and Maintenance in London.

When buying equipment, whether it’s a shop window, a cabinet or a camera, each customer receives a technical passport, where the operating conditions of the equipment, the rules for servicing and loading products are specified. However, in most cases, these rules and requirements are not complied with. This leads to premature wear and equipment failure.

Often, shop windows in stores are overloaded with products (while they should be used only for displaying products), there is no normal heat exchange and the compressor is simply “choking” because everything around is littered with boxes. And how, under such conditions, should the equipment work for 5-10 years? If elementary operating conditions are not met.

It should be mentioned another factor of operation that disrupts the operation of refrigeration equipment - this is participation in the repair of non-professionals. When the owners decide independently (without the participation of the seller or service organization) to replace the compressor, components or automation components. In this case, the cause of the damage is not thoroughly investigated, and the equipment is being repaired in a hurry. Naturally, the reliability of the "reconstructed" equipment is not guaranteed, and its further work becomes simply unpredictable. In no case should such mistakes be made. Everything must be approached responsibly.

And in conclusion, I wanted to give advice to all buyers of commercial refrigeration equipment - purchase equipment from such companies, which will select the equipment for your specific tasks and will ensure its high-quality maintenance in the future. Read the terms of delivery, installation, warranty service. This will allow you to make an objective decision and choose reliable equipment. I will further instruct to those who don’t know to about Refrigeration equipment they must hire any Best Air Conditioning Company in London that know Best Refrigeration Services in London as well as Best Refrigeration Repair and Maintenance in London. It will be favorable for the buyer to purchase the best refrigeration equipment.

Use of refrigeration equipment in stores

This Topic is about “Use of Refrigeration Equipment in Stores”. Hire Best Air Conditioning Company in London that’s know Best Refrigeration Services in London as well as Best Refrigeration Repair and Maintenance in London.

 We have many years of experience in servicing demonstration and industrial refrigeration equipment, which allows us to state that the fulfillment of the main conditions for the use of commercial equipment makes it possible to operate it without problems for 4-5 years. And this applies not only to foreign trademarks, but also to our manufacturers, where, as a rule, equipment includes cooling systems of proven European manufacturers. But it often happens that difficulties for store owners arise in the first months, even after a year of work, when the warranty period of operation often lasts.

 What are the main reasons? According to statistics, only in 17% of refrigeration breakdowns, the reason was in a factory marriage. Other problems are caused by the owner of the store and the sellers working with the equipment. What are the main reasons for this?  Previously, we described the nuances of operating refrigeration equipment at elevated temperatures. Of course, you should definitely find out about all the nuances discussed in the article, since in this article we will not consider this. But some user of refrigeration doesn’t care about their refrigeration like didn’t Best Refrigeration Repair and Maintenance in London. On the other hand, our companies are not providing the Best Refrigeration Services in London so that the equipment is not properly work for the long time.

 The main sources of improper operation of the trading equipment can be classified according to the sources of their undertakings: 

- low personnel discipline;  - violation of mandatory tips on the operation of commercial equipment;  - factory defect and technological interruptions.

 Consider these reasons. Technological failures, most often, are small and non-critical problems. It is possible that the light bulb will blow, the demonstration glass angle will disperse, the control unit will give an error controlling the operation of the equipment, etc. Practically it can’t freeze lari, for example, through the manufacturer’s fault. After all, there is nothing special to break! 

 Most often, the source of damage is the first two factors. Among the main modes of operation, which are neglected by the owners and managers, should be noted: neglecting the external temperature for operating the equipment, recommended operating modes directly for the device, excess display volumes, the complete absence of mandatory routine maintenance of the unit, unprofessional installation and location. Get Best Refrigeration Services in London as well as Best Refrigeration Repair and Maintenance in London, please contact us.

 Let us emphasize that virtually all manufacturers of demonstration refrigeration devices put pointers for the volumes of goods loading, which should not be exceeded. Failure to comply with all these standards leads to the equipment operating in the “wear out” mode, which, after a certain period of time, can completely destroy the cooling unit itself.

 So, for example, it is not uncommon for the manager to save himself not enough refrigerated display windows for displaying products in order to save. During operation, the quantity of goods may exceed the planned rate and it is placed in violation of the norms of operation. The refrigerator begins to be used in an elevated mode, and after a certain period of time it may completely fail. Therefore, we advise you to install refrigeration units in quantities that are slightly larger than necessary, so that even if one refrigerator fails, it is possible to reserve work and insure against losses.

 An important point in the proper use of demonstration refrigeration units is the strict frequency of technical work. The recommended frequency of routine maintenance does not exceed 8 weeks, and in the summer no more than 4 weeks. Failure to follow the recommendations on the frequency of maintenance work is also one of the main issues of the failure of trading units.

 Finally, practical advice - one of the most popular reasons for the breakdown of commercial equipment is unlearned, low accuracy, lack of awareness and the desire to experiment with store personnel. Sometimes it happens that sellers do not know the basic requirements for using a refrigerator. And, it happens accidentally or unconsciously that they block the opening of the ventilation device, throw paper onto the unit, blocking the approach of cool air, etc. It rarely happens that the staff are just interested in testing the switching of the refrigerator parameters, clicking the tumblers. This leads to a change in the load, and sometimes to the failure of the equipment.

 Therefore, the awareness and frequent instructions of dealers who work with refrigeration equipment, will save you from damage and financial losses. If you want to get Best Refrigeration Services in London or Best Refrigeration Repair and Maintenance in London, please hire Best Air Conditioning Company in London.

TYPES OF AIR CONDITIONING SYSTEMS

This article is about to ��Types of Air Conditioning System”. If you want to hire Best Air Conditioning Company in London and avail Best Air Conditioning Services in London, Best Air Conditioning Installation in London. Please Contact Us.

Depending on the scale of construction and the needs of the facility in refrigeration capacity, various types of air conditioning services in London are provided. These can be either simple systems for servicing a single room (split-systems) or large refrigeration complexes designed to cool the premises of an entire building (chiller-fan coil).

In addition, there are intermediate architectures of cooling systems that are optimally suitable for large and medium-sized objects. These include multi-split systems and VRF systems.

Constant Cooled is one of the best air conditioning company in London is engaged in the design, installation, commissioning and maintenance of air conditioning services in London of all kinds for various objects: apartments, cottages, office buildings, business centers, public and administrative facilities, catering enterprises, etc.

Constant Cooled has the necessary competencies and equipment to perform all work on air conditioning installation in london and ventilation systems and is ready to connect at any stage of the construction of the facility.

If you need to install air conditioning or equip the entire building with air conditioning services in london, call us. You can also order a call back or leave a request for work. Our manager will contact you to clarify the details and departure to the site. 

Split system

Split systems are ideal for apartments, small offices and any other single rooms. This is the simplest type of air conditioning installation in london, consisting of two blocks - indoor and outdoor. In this case, the internal unit can be of different execution.

The most common type of indoor unit - wall. It can also be a cassette, floor-ceiling, duct or column.

Type of indoor unit is selected based on the design of the room. So, cassette and channel blocks are concealed mounting units (this means that the block is not visible in its entirety, only a certain part of it is visible - a decorative panel or grille). Wall, floor-ceiling and column air conditioners are among the units of outdoor installation, that is, they are fully visible after

air conditioning installation in london.

Multisplit-systems

Multisplit-systems differ from split-systems by the ability to connect not one, but from two to six indoor units to one outdoor one. The benefit of such systems is obvious - there is often not enough space to accommodate several outdoor units on the facade of the building, and the appearance of the facade will be ruined. The ability to do with one outdoor unit solves these problems. Multi-split air conditioning installation in London is advance type of best air conditioning services in London.

Thus, multisplit-systems can simultaneously serve up to six rooms. Therefore, they are great for multi-room apartments and small offices.

However, it should be remembered that all indoor units will have one outdoor unit. As a result, in case of any breakdowns in the outdoor unit, all indoor units connected to it will stop working.

VRF-systems (multi-zone air-conditioning systems)

More progressive and large-scale is a multi-zone air-conditioning system (VRF-system). It can include up to 80 indoor units with a total cooling capacity of several hundred kilowatts. In practice, this means that it is a multi-zone system that can provide rooms with an area of ​​several thousand square meters with cold - a floor of a large building or a small building as a whole.

Small VRF-systems are used for best air conditioning installation in london of cottages, shops and other objects. Large systems are suitable for office and administrative buildings, cafes and restaurants, shops and supermarkets.

Multi-zone air conditioning systems have much more opportunities in terms of monitoring and dispatching climate systems. This is very important for facilities where BMS (building management system) is being implemented.

In terms of terminology, we note that "multi-zone air-conditioning systems", "VRF-systems", "VRV-systems" and "air-conditioning services in London with variable refrigerant flow are one and the same. The only term is VRV (Variable Refrigerated Volume, variable refrigerant consumption) was patented by Daikin, therefore all such systems of this manufacturer are called VRV systems. Other manufacturers have come up with a different term - VRF (Variable Refrigerant Flow) and use it.

Chiller Fan Coil System

Finally, the most complex, capacious and flexible is the air conditioning services in london, built according to the "chiller-fan coil" scheme (chiller air conditioning system).

The chiller system is well suited for medium and large objects (from 100kW) and can be designed taking into account any features, features, such as the remoteness of the rooms to be cooled, the outdoor temperature range, environmental safety, etc.

The principal difference of the chiller system from all the others is that it is not coolant that circulates in the pipelines, but cold water (or non-freezing glycol solution for the case of winter operation of the system).

Note that there are several types of chillers: with a built-in or remote condenser and with a condenser of air or water cooling. This classification provides the necessary flexibility in configuring the system, which allowed this type of equipment to largely occupy a niche, as mentioned above, medium and large objects.

It is important to note that for the chiller cooling system, as a rule, its own pumping station is designed. This allows you to include in one system all the premises of a large object, without breaking them into several systems, which saves capital and operational costs.

Precision air conditioners

Precision air conditioners are markedly different from other types of air conditioning installation in london. They are designed to more accurately maintain the temperature in the room (hence the name of the technology: precision means "accuracy, clarity, accuracy"). Therefore, more precise control mechanisms and increased air flow are used in best air conditioning services in london of this type. In addition, precision air conditioners are able to maintain not only the temperature, but also the humidity of the air.

We also note that precision air conditioners are noticeably more powerful: the cooling capacity ranges from 6 to 200 kW. Since they are designed to work not only in summer but also in winter, the compressor and all controls are transferred to the indoor unit. On the street is installed only a capacitor.

Precision air conditioners are used for facilities with increased requirements for temperature and humidity (industrial facilities, data centers, server rooms, etc.). In order to increase reliability, there are modifications of precision air conditioners with double coolant inlet (from two condensers, from two chillers, from a condenser and a chiller simultaneously).

Specialists of Constant Cooled are always ready to advise you on all matters related to ventilation and air conditioning systems.

Constant Cooled professionally installs air conditioners in apartments and cottages and carries out construction, best air conditioning installation in london and commissioning works on the ventilation and air conditioning systems of various buildings: residential, public, administrative facilities, cafes and restaurants, shops and supermarkets.

In addition, the Constant Cooled is engaged in the design, air conditioning installation in london, air conditioning repair and maintenance in london of climate systems. Our manager will contact you, give the necessary advice and agree on the arrival time of the engineer.

DESIGNING A CENTRAL AIR CONDITIONER

This article is about “Designing a central air conditioner”. If you want to design and avail best air conditioning services in London and air conditioning service london. You can hire best air conditioning company in London for the best air conditioning installation in London & air conditioning repair and maintenance in London

The central air conditioner is non-autonomous, that is, it needs an external source of cold or heat for work — cold water from the chiller, freon from an external compressor-condensing unit, hot water from the central heating system or a boiler. In addition to cooling or heating, the central air conditioner can ventilate, clean and humidify the air. The treated air through the duct system is distributed throughout the premises.

Due to the modular structure, depending on the agreed project, a different assembly kit is supplied before air conditioning installation London to achieve operating parameters. Globally, the size of the air conditioning installation london depends on their performance, power, additionally installed components. The most frequently used sections are: fan; cooling; heat; filtration; moisturizing; heat recovery. The mode of operation of the house, or of certain premises, sanitary and hygienic requirements, economic feasibility, drawn up project documentation - all this affects the basic equipment of the installed central air conditioning installation london. Equipment selection When designing the system, the calculation of the evaporative section of the central air conditioner is carried out in accordance with the requirements of SNiP 2.04-05-91. In particular, for London, the outside air temperature in terms of parameters B Tн = 28.5 ° С, and the specific enthalpy is 54 kJ / kg. The best air conditioning company in London is responsible for all air conditioning services London and air conditioning repair & maintenance in London. If anyone don’t provide best air conditioning services in London, you can contact us.

 According to these data, using the program of selection of central air conditioning installation london, the heat exchanger of direct cooling is calculated for the evaporative section. When performing the calculation, it is necessary to set the boiling point of freon in the heat exchanger (evaporation temperature). Standard for R22 this value is 7.5 ° C. However, in practice, in order to make the cost of the air conditioner lower, the choice of equipment is carried out at a boiling point of + 5 ° C. Thus, the total temperature difference on the heat exchanger (the difference between the air temperature at the inlet and the boiling point of freon in the heat exchanger) will be 23.5 ° C. The optimal recommended value is 16-20 ° C.

 Design features for office and industrial buildings of a large area, as well as high-class buildings, central air conditioning installation london systems are used. Central air conditioning installation london systems are a complex of equipment designed to maintain climate parameters in the premises of the entire building. The most common central air conditioning services London scheme is chiller + fan coil units + central air conditioning. The supply of fresh air and its treatment (cleaning, heating and humidification in the winter, cooling in the summer) is done using a central air conditioner consisting of a number of sections. The flow of air supplied by the air conditioner to the premises is calculated in accordance with the requirements of the relevant sanitary standards. For the normal functioning of the central air conditioning installation london system, a whole range of auxiliary equipment is needed. These are pumps for circulation of chilled water, systems for filling water with a cold supply circuit Control Valves Control and management system. The whole complex of auxiliary equipment together with the chiller is called a refrigeration station or a refrigeration center. To accommodate the equipment of the refrigeration station requires a separate room of a fairly large area. Maintenance of the central air conditioning installation london system should be carried out by highly qualified personnel. Capital costs for the supply of equipment and air conditioning installation london are also quite high. However, with all the visible drawbacks, central air conditioning installation London systems have a number of significant advantages: the treatment of outside air in the central air conditioner allows to exclude from the heat balance the heat introduced into the rooms with fresh air and install indoor units of lower power than in systems with fresh air without pre-cooling; the design of the fan coil allows you to use them for the purpose of air heating of premises in the winter; the practically unlimited total cooling capacity allows arranging a single refrigerating center for several buildings, and the variable power of refrigerating machines makes it possible to operate the cooling center at low loads at the time of putting part of the premises into operation, further increasing the number of indoor units as buildings are being built or renovated; the length of the refrigeration supply lines, in contrast to the freon systems, depends only on the capacity of the installed pumps and the distance between the indoor unit of the water system and the refrigeration center can be an order of magnitude greater than that of the freon systems between the indoor and outdoor units; The chiller-fankoy system is highly flexible in terms of changing the system configuration, for example, when changing the room layout, repairing or replacing a failed fan coil unit, installing an additional indoor unit, stopping the system is not necessary, unlike the freon system. The choice of a particular conditioning scheme depends on a number of conditions. For newly built office and industrial buildings of a large area or for reconstructed buildings - monuments of architecture, the options with multizone split-systems or central air conditioning installation london are preferable. It should be remembered that for office premises of class "A" it is allowed to use only central air conditioning installation London systems, for rooms of class "B" split-systems are allowed. For the air conditioning services london of small office premises, the cost of the air conditioning installation london system is undoubtedly decisive and the use of split systems is quite natural here. In any case, each project requires an individual approach and the question of the applicability of a particular best air conditioning installation londoan and best air conditioning services london system can be solved only by having the most complete picture of the object.
