Benefits of a Scroll Compressor

Specially designed, a scroll compressor or scroll pumps is usually works in a circular motion, as opposed to up and down piston activity. They possess two identical spiral shaped or scroll shaped parts that move constantly in one direction. There's a lot more service center prefer to utilize the scroll compressor or scroll pumps for their services of HVAC system, for it will contribute a more reliable and more efficient way than traditional types. The mechanism and manner of operation of the scroll compressor is one fixed scrolls which remain stationary and another is moving using an electric motor to rotate the other. When this actuation happens, it compresses the air or refrigerant between two scrolls for your HVAC system that are slowly pushed to the center of the scrolls. Naturally, the pockets of air or refrigerant that passes between the two scrolls will cause the reduction of the volume of the gas. Using a scroll compressor for your HVAC system will definitely offer a saving of more energy and a comfortable condition in your home. Learn more about float design labs, go here. 

The benefits of using the scroll compressor is it reduces the noise for it contains fewer moving parts and have a less torque variation compared to the reciprocating compressor. Find out for further details on dry scroll pump  right here. 

There are two types of scroll compressors, the single stage compressor and the two stage compressor both entertained different speed and accuracy. Commonly installed for home cooling and heating systems is the single stage compressor. Consider as the simplest and least expensive type, the single stage unit of scroll compressor operate only at one speed but can cool or heat the entire home efficiently. Two stage scroll compressor, on the other hand, will operate two different speeds, to offer closely to the cooling and the heating produced output to satisfy the convenience and need of the users. Frequently, the two stage compressor will provide a more efficiency of saving energy, because you have a choice of your desired temperatures at your own convenience and capacity. Below are some reasons and beneficial advantage in having a scroll compressor in your home. 

Using a scroll compressor or scroll pump will offer you a much savings on your utility bills, for it gives the same amount of hot or cooled air as the larger piston compressor will do.

Because it has a limited moving parts, scroll compressor is more durable than the piston compressor, because it provides a less breakdown compared to other traditional pumps and even works overtime when needed.

Your air conditioner is easily the most important piece of equipment in your home during the hottest days of summer. When the outside temperature becomes unbearably humid, you will count on your AC to keep you and your family safe and cool.

If you have an older cooling system, it may be losing its ability to effectively cool your home. By trying to keep up with an inefficient system, you could also put your family's health at risk. One of the biggest health risks of running an old air conditioner is the spread o microorganisms such as fungi, bacteria, and pollen. While not every type of fungus is infectious, but some of the dangerous ones can travel in the ducts and therefore circulate throughout your home.

If you have anyone in your home suffering from asthma, bronchitis, or other respiratory problems, your old AC can aggravate their state. Someone with a preexisting condition is more susceptible to catch a lung infection or to have a severe reaction to the toxins and microorganisms being circulated by your old AC system.

If you have allergies, you're probably aware that pollen, dander, and allergens can actually worsen the situation. Unfortunately, outdated air conditioners are unable to effectively filter out these contaminants before they reach your indoor space.

In addition to health risks, operating an old, inefficient cooling system can be a fire hazard.

CREATING A STRONG MEDICAL GAS SPECIFICATION

Pattons Medical Manufactures>CREATING A STRONG MEDICAL GAS SPECIFICATION

WHAT IS A MEDICAL GAS SPECIFICATION?

A Medical Gas Specification is a document issued by Plumbing Designers that serves to define the parameters of the materials and equipment to be installed in a facility during a construction project. This document ensures compliance with local codes and must be updated and revised for each project, including technology and code changes depending on the location.

There are many benefits of having a strong specification, including making reviewing submittals easier and reducing change orders. Another advantage is that they ensure the owner/end-user have the products that meet their expectations and align with their comfortability. Having a strong specification also results in less RFIs from the contractor, by ensuring drawings and specification complement one another. They aid in understanding the equipment options to allow the owner strong value engineering options.

GENERAL DEFINITION AND GUIDELINES

This section will be focused on where you define the project code and compliance. There are important things to remember and essential questions to ask when creating these guidelines.

Do you have the option to always design to the latest code?

Will you allow manufacturers to not be specified?

What are your preapproval requirements?

It is crucial to define the code revision based on project location. You will also need to define the requirements under plumbing scope versus other disciplines such as electrical.

PRODUCT SECTION: ACCEPTED MANUFACTURERS

When thinking about accepted manufacturers, there are some common mistakes that are made. Many of these errors come from the way that they are listed, including listing manufacturer representatives and not the manufacturer themselves. Another is listing industrial manufacturers when they have the potential to provide systems that are not compliant with NFPA 99. Including manufacturers of raw materials instead of complete systems is another common mistake.

It is essential to remember to list only relevant manufacturers and one manufacturer based on installed base.

PRODUCT SECTION: MATERIALS

Outlets

Pattons Medical gas outlets are designed for gas distribution in centralized areas of several industries and are available in four styles. This information can also be found on the Pattons Medical website.

Pin Index – This means you have two pins that your secondary equipment lines up with to plug. The bottom pin moves to make it gas specific.

Ohmeda

Diamond Series – Diamond 1, 2, 3 and DiamondCare (proprietary of BeaconMedaes)

Latch Valve Style – This is where you have two latches that you push down on which opens the teeth that are gas specific.

Chemetron – Series 400, 500

DISS – The threads in this category will be different depending on the gas specific.

Threaded

Geometric – You will have a different shape depending on the gas.

Puritan Bennett

Zone Valve Boxes

There are several standards to follow when implementing zone valve boxes. This includes material, pressure rating, and ball valve type. In addition to this, gauges are required and you must have cover requirements listed. Information about medical zone valve box specifications can be found on the Pattons Medical website.

Zone Valve Box with Sensor Provisions

Some benefits of this option are that there is ease of certification because the sensor location can be confirmed without needed ceiling access. Also, each gas has a DISS demand check that the sensor is installed on to ensure the gas in correctly identified. Another advantage is that this particular one does not need to be project specific; it can be standard.

Zone Valve/Area Alarm Combination

A benefit of this is specifically for very small facilities, where the zone valve is close to the nursing station so the area alarm can be monitored.

Alarm Panels

For alarm panels, the standards are found within the wiring and programming requirements. Pattons Medical has many resources regarding alarm panels, including specification information and a webinar entitled "Overview of Medical Gas Alarms and Zone Valve Box Placement."

Ethernet for Master and/or Area Alarm Panels

A benefit of this is connecting to a building management system. However, it’s important to consider: does the owner want every alarm panel connected or only the master? Ethernet capability adds cost to every panel and most value engineering practices remove Ethernet from the area.

If the facility wants to keep an eye on their source equipment, then the master alarm panel should be ethernet capable. On the area alarms, the facility will not need this, which will reduce unnecessary costs.

MANIFOLDS

Standards for manifolds include following location and installation requirements as well as header requirements. It is important to follow automatic changeovers. You can find more information on the Pattons Medical website by viewing our “Overview of Medical Gas Manifolds” webinar or by navigating to our manifold specifications.

Bulk – usually provided by owner or a contract with the owner

Liquid by Liquid

This particular option is equipped with electronic controls to reduce venting and is also equipped with a “look-back” control to ensure the liquid container is fully utilized.

High Pressure by High Pressure

This option utilizes dome biased regulators. It reduces the need for all gases. Another thing to note is that it does not allow shuttle valves which are a single point of failure.

Medical Air Compressors

Medical Air Compressors have a redundant system including a compressor, dryer, and filtration. They have additional standards such as a desiccant dryer, dewpoint monitor, CO monitor, and filtration. Medical Air Compressors follow the standard of oil-less technology. To learn more about Pattons Medical air compressors, visit our website.

Scroll/Reciprocating/Rotary Screw

Dryers

A question to consider is: do you still allow refrigerated dryers?

Dryers have demand-based purging which essentially means the dewpoint monitor controls the dryer purging to reduce wear and tear on the compressor. Desiccant cartridges versus loose desiccant should be compared; eliminate dusting that can cause failure and downstream contaminants.

Control Panel – touchscreen and/or manual controls

Additional System monitoring of the system performance such as System Health

Medical Vacuum Pumps

Medical Vacuum Pumps are also a redundant system and include cover requirements listed. Pattons Medical offers more information on vacuum pumps and the ability to request a quote on our website.

Technology: Claw/Lubricated Rotary Vane/Oil-less Rotary Vane

Claw Technology VFD or not

Claw Technology – O2 Safe

Control Panel – touchscreen and/or manual controls

Additional system monitoring of the system performance such as System Health.

EXECUTION: CERTIFICATION

There are a few important questions to ask when looking into 3rd Party Certifications. Are you comfortable with the certifying selling the equipment for the project and then certifying the installation? Do you want a certifier that only provides certification and does not provide the equipment? By listing the certifier in your specification, you are potentially making your specification proprietary.

Pattons Medical recommends not listing certifier in your specification and making that proprietary because it can potentially impact the budget and quoting of the job. It is required that every job be certified to a NFPA 99, you need to have this done before you can open the building.

EXECUTION: SERVICE, START-UP, AND TRAINING

Many manufacturers partner with service organizations, so it is essential to require the manufacturer to have local service. It is important to not specify service as it could limit the facility in getting appropriate support. The manufacturer is responsible for starting up the equipment because it ensures it is installed correctly outside of NFPA 99. It will also guarantee that the equipment will run smoothly for the end user – including drip legs installed, ambient temperature, among other essential aspects. In addition to all of this, the manufacturer is responsible for training the facility on the equipment.

OVERVIEW

Overall, it is important to update your specification as it aligns with your project. Remember to clean up your approved manufacturers list, delete sections that are not relevant to the project that the specification applies to, and make choices that are needed for technologies. Pattons Medical specification makes that easy by putting choices in red or blue.

You can find the Pattons Medical specification guide on our website.

The Pattons Medical team is here to help you, you can find your local representative on our website. If you aren't sure which rep to contact, you can search by state to figure out which member of our team can help you on any project.

AN OVERVIEW ON MEDICAL AIR PACKAGES

Pattons Medical Manufactures>An Overview on Medical Air Packages

A patient in the hospital who needs assistance breathing, either during surgery or through a ventilator, is administered medical air. Medical Air is defined in National Fire Protection Association (NFPA) Code 99 2018 in 5.1.3.6.1 to have the following characteristics:

It shall be supplied from cylinders, bulk containers, or medical air compressor sources, or it shall be reconstituted from oxygen USP and oil-free, dry nitrogen NF.

It shall meet the requirements of medical air USP.

It shall have no detectable liquid hydrocarbons.

It shall have less than 25 parts per million (ppm) gaseous hydrocarbons.

It shall have equal to or less than one milligram per cubic meter (mg/m3) of permanent particulates sized one micron or larger in the air at normal atmospheric pressure.

The air is delivered through a distribution piping system that ends with a medical air outlet within the room. Outlet requirements per room are governed by American Institute of Architects (AIA) Guidelines for Design and Construction of Hospitals and Healthcare Facilities.

Equipment is plugged into the medical air outlet to treat the patient. Many studies have been done determining the load required for medical air compressors. The sizing can be calculated using several methods. The U.S. Typical Method is the standard calculation for medical air in the United States. To calculate by this method the following steps are taken:

Count all outlets that will be served by this system by occupancy.

Multiply by simultaneous use factor.

Add the sum of all occupancy.

Add the number of ventilators.

This sizing process attempts to size by “worst case scenario,” which means all rooms would be occupied and using some amount medical air. Ventilators being the largest consumer of medical air especially adds to the total. It is highly unlikely all outlets would be used at one time in a facility; however, the facility has to be prepared and equipped for that scenario. This leaves many facilities frustrated with what they consider grossly oversized medical air compressors.

MEDICAL AIR CENTRAL SUPPLY SYSTEMS

NFPA 99 5.1.3.6 details the requirements and the limitations of medical air central supply systems and their installation within a healthcare facility in the United States. The defining requirement 5.1.3.6.2 Uses of Medical Air states that medical air sources shall be connected to the medical air distribution system only and shall only be used for human respiration and calibration of medical devices for respiratory equipment.

Medical air cannot be used in central sterile, to run instruments, or any other use outside of patient respiration. Therefore, multiple air compressors are used within a healthcare facility, but this article will only focus on Medical Air Central Supply Systems.

Oil free air compressors are used to eliminate the potential for hydrocarbons. The most common technologies are scroll, reciprocating, and rotary screw air compressors. In addition to the air compressor, the package normally contains aftercoolers, dryers, filters, receiver and monitoring equipment, such as a dewpoint monitor and CO monitor.

REDUNDANCY REQUIREMENT: AN IMPORTANT SIZING FACTOR

No one point of failure is allowed to ensure patient safety. NFPA 5.1.3.6.3.9 (B) states that medical air compressors shall be sufficient to serve the peak calculated demand with the largest single air compressor out of service. In no case shall there be fewer than two air compressors.

This means redundancy is required and one air compressor is never allowed. The smallest would be a duplex package. The redundancy also applies to filtration and dryers as well. When sizing an air compressor, it is important to size with the load being maintained even with one unit out of service. Therefore, in a triplex skid, two air compressors can run with one as backup. A quad package can run three and so on. The air compressors will still all run in sequence to maintain even run life on all the air compressors.

An efficient way to meet the peak calculated demand and satisfy the redundancy requirement is with multiplexing smaller horsepower (hp) units. In the past, large industrial air compressors were installed, with large being 30- or 50-hp in medical air applications. This means if one Operating Room is put into use, or one ventilator is brought on-line, a 30-hp air compressor would be started up to meet the demand. This air compressor would run two to three minutes, meet demand, and shut off. This cycle is repeated throughout the life of the unit.

By multiplexing smaller hp air compressors, such as 10- or 15 -hp machines, a facility can reduce their electrical consumption. When a demand is created only one air compressor runs. If that one air compressor cannot meet the demand, then another air compressor can come on and so forth (with one staying off for redundancy). Therefore, the facility is running one 15-hp air compressor versus a 30-hp machine. In the majority of applications, only one air compressor handles the load.

Multiplexing also allows for expandability. Healthcare construction projects are often open-ended leaving flexibility in the services that the hospital is going to provide. Also, due to budget constraints, sometimes space is left shelled for future expansion. Instead of guessing at the future or sizing for future, it is possible to put expandable panels and leave space on skids for future modules. This keeps capital costs down, and the facility will have a clearer understanding of its medical air usage.

Finally, multiplexing multiple scroll air compressors takes dramatically less space, saves considerable money on installations and has lower capital costs than Variable Speed Drive (VSD) rotary screw air compressors. Pattons Medical can have a complete medical air package with multiple scroll air compressors shipped as a complete single point connection package. In new construction, this will save the contractor any additional piping and electrical wiring for components. There would be a braze for the inlet/outlet and one wiring connection. For replacement equipment, the skids can be broken apart to fit through a 30-inch door and have unions for the connections when put in place.

THE INS AND OUTS OF DESICCANT DRYER TECHNOLOGY

Dryers are an integral part of the medical air compressor package and can have an impact on the sizing and efficiency. To maintain the requirement of a maximum dewpoint of 32 °F at 50 to 55 psi at any level of demand, and allow for flexibility in skid design, desiccant dryers have become the standard for medical air packages. They perform well in low-flow conditions that are common with medical air demand.

Desiccant dryers utilize towers that contain cartridges of activated alumina. The cartridge design versus loose desiccant eliminates dusting from desiccant and is sized based on demand. Therefore, the amount of air purged will be dramatically reduced requiring less demand from the air compressor. Desiccant dryers require a purge to regenerate the desiccant to continue the ability to dry the air. It is imperative for efficiency with medical air to utilize controls for demand-based purging. The dewpoint is monitored through the dewpoint sensor. In demand-based purging, the purge does not take place until the dewpoint reaches 14 °F. This almost eliminates the air compressor running for purge outside of demand. Another benefit is the dryer can be mounted horizontally or vertically to achieve smaller footprints of the overall package.

MEETING THE NEEDS OF SMALLER HEALTHCARE FACILITIES

During the last 15 years, smaller healthcare facilities have been built to offer less acute services. These facilities are either located on the campus of larger hospitals or found as standalone buildings.

For these applications the sizing of the medical air is the same, however, the loads are much smaller. High-pressure manifolds utilizing medical air cylinders are allowed by code to deliver medical air. This requires the owner to make a financial decision of either a larger capital cost of an air compressor or the ongoing operational cost of purchasing medical gas cylinders.

If the owner decides to install a medical air compressor, the space allotted for medical air compressors is usually quite small. The location is also much closer to patients than in a large hospital setting. This led to the scroll type air compressors being used for medical air. Scroll units are much quieter and smaller than either of the reciprocating or screw type. By utilizing vertical tank configurations and appropriately sized desiccant dryers the skids can be as small as three by four feet.

INVOLVE MEDICAL GAS SPECIALISTS IN THE PROCESS

It is imperative in a replacement scenario that a facility meet with a medical gas specialist to have a medical gas survey completed. This will confirm the sizing done initially for the facility was accurate and will address any changes in acuity or services since the original air compressor was installed. The medical gas specialist will confirm the outlet counts, interview respiratory therapist, and determine if there are any code issues that will need to be addressed with a replacement. Specifically, that the inlet is code compliant and the master alarm panels have the appropriate points. Oftentimes this is missed and can affect the new air compressor being certified.

A Spotlight on Lennox XC20 Air Conditioner

The world has seen amazing technological advancements in the past decade, and the HVAC industry is no exception. From higher SEER ratings to better filtration systems, advancements in cooling technology are not only improving home comfort, but also saving homeowners hundreds of dollars per year.

If you still have one of the older air conditioner models and have noticed a significant downward slide in its performance, you may want to consider looking into upgrading to a new, more efficient cooling system.

A trusted HVAC company in Columbia Heights MN notably Marsh Heating and Air Conditioning can help you decide whether it is time to replace your old, inefficient air conditioner.

Repair or Replace?

First off, understand that the age of your equipment matters. A well maintained air conditioner lasts anywhere from 10 to 15 years. Take note of the words “well maintained”. If your air conditioner has not been receiving regular professional maintenance, you may need to replace it much sooner.

If you notice an increase in your repair costs, including replacement parts, it will make more sense to get a new one.

Older air conditioners use R22 refrigerant, which is going to be discontinued soon because of its harsh effects on the environment.

In addition, consistently higher utility bills without a comparative increase in your cooling strategies maybe a sign of a failing air conditioner.

If any of these issues seem familiar to you, replacing your air conditioner might be the right choice. While investing in a new unit requires a higher upfront cost, you will be rewarded with lower monthly bills and better comfort throughout your home.
