#EVAP system

[hometowne-auto-repair-and-tire]

While looking over a Ford Fiesta, one of our technicians saw the canister breather hose was torn.

This hose, also called a “vent hose”, is connected to the canister that filters the EVAP gases off the fuel tank. 

These gases either go through a filter process before they are safely released through the canister breather hose into the atmosphere, or they are moved back to the fuel tank.

It looks like one bad valve solenoid was all it was taking to make my truck act stupid. A $30 part. Achilles type vibe I guess.

Cooling with Nature: Exploring the Science Behind Indirect Evaporative Cooling

As temperatures continue to rise, traditional air conditioning systems are becoming less sustainable due to their high energy consumption and environmental impact. However, there’s a more natural and energy-efficient cooling solution that’s gaining attention: indirect evaporative cooling (IEC). Unlike conventional air conditioning, which uses refrigerants to cool air, indirect evaporative cooling taps into the power of water and airflow to provide a more eco-friendly alternative. Let’s dive into the science behind this technology and explore how it works.

What Is Indirect Evaporative Cooling?

Indirect evaporative cooling is a process that uses the natural evaporation of water to cool the air without directly mixing the water with the air you breathe. This is achieved by passing warm air over water-saturated materials or through a heat exchanger that cools the air before it enters the living space.

In simpler terms, it’s a way to cool air using water evaporation, but without the drawbacks of adding moisture to the indoor air, which can cause discomfort in humid climates.

The Science Behind Indirect Evaporative Cooling

The process of evaporative cooling is rooted in basic thermodynamics. When water evaporates, it absorbs heat from the surrounding air. As water molecules transition from liquid to vapor, they take energy (in the form of heat) with them, thereby lowering the temperature of the air around them.

In indirect evaporative cooling, the key distinction is that the air and water never directly mix. Here’s how it works:

Warm air enters the system: Air from the outside (which is typically warm) enters the cooling system.

Air passes through a heat exchanger: The warm air flows through a heat exchanger, which is a series of materials designed to maximize the contact area between the warm air and water-saturated surfaces. As the warm air passes over the water, it absorbs heat from the air.

Cooling the air: As the water evaporates, it absorbs heat from the air, which cools it down. However, the moisture doesn’t mix with the air passing through the heat exchanger, so the indoor environment stays dry.

Cool, dry air enters the space: The cooled air is then circulated into the building, creating a comfortable, refreshing environment without introducing excess humidity.

Why Choose Indirect Evaporative Cooling?

There are several compelling reasons to consider indirect evaporative cooling:

Energy efficiency: Unlike traditional air conditioning systems, which require large amounts of electricity to operate compressors, IEC systems use minimal energy, making them a more sustainable option. They are often powered by fans or pumps, reducing the carbon footprint of cooling your space.

Low water usage: Despite using water for cooling, indirect evaporative cooling systems are quite water-efficient compared to other evaporative systems. The water is primarily used to cool the air, and in many cases, it’s recycled through the system, reducing waste.

Environmentally friendly: Since IEC systems don’t rely on refrigerants (which can be harmful to the ozone layer), they offer a more environmentally conscious way to maintain comfortable indoor temperatures.

Comfort without humidity: Unlike direct evaporative cooling systems, which can leave the air feeling damp or clammy, IEC ensures that only the temperature is reduced, leaving the air dry and comfortable. This is particularly beneficial in areas with high humidity.

Applications of Indirect Evaporative Cooling

Indirect evaporative cooling is ideal for dry, hot climates, where it can offer significant energy savings while maintaining comfort. It’s especially popular in regions like the Southwest United States, parts of Australia, and the Middle East. Additionally, IEC systems are increasingly being integrated into commercial buildings, schools, and even industrial settings where temperature control is essential without incurring high operational costs.

Final Thoughts

As our global climate continues to warm, exploring alternative cooling solutions like indirect evaporative cooling becomes crucial for both environmental and economic sustainability. By harnessing the power of nature’s cooling mechanism—evaporation—we can enjoy comfort without contributing to the environmental burden of traditional air conditioning.

If you're looking to lower your energy bills and reduce your carbon footprint, indirect evaporative cooling offers an innovative and effective solution. Whether for residential or commercial use, it’s a technology that keeps things cool in a natural way.

Evap cooling system

Evaporative cooling systems are an excellent and eco-friendly alternative to traditional air conditioning, offering energy-efficient cooling for dry, hot climates. Degree Day Private Limited provides this evap cooling system as an affordable and sustainable option for both residential and commercial use, making them a great choice for reducing energy consumption and improving indoor comfort. However, like all cooling systems, evap cooling system have limitations and are most effective when used in the right environmental conditions. When properly maintained and used in appropriate climates, these systems can significantly enhance comfort while reducing environmental impact.

By now, it has become an agonizing cliche that any amount of work on a modern car will terminate in you losing at least one 10-millimetre socket. "Oh no, my 10mm is missing," you'll groan to your friends, who immediately respond with haw-haw looks and jokes. Being the butt of such a horrible stereotype is far worse than losing your socket, which is itself a pretty bad day at work.

There are many techniques that don't work. I myself often write with a Sharpie on the socket "9.5mm," in the hope that it will confuse the curse enough that they will not be lost. I buy ones in weird colours. I use a giant neodymium magnet on the fender so they can't roll away and into the mouth of a nearby blower motor. Nothing works.

Official Chinese government numbers indicate that nearly 60% of the cars their metal recyclers crush, by weight, are 10-millimetre sockets. Your entire washer and dryer set is probably made out of the stuff that fell out of my pockets last year when I was trying to yank an evap solenoid.

Of course, there's a real solution too, and it just happens to be the same kind of solution that capitalism always presents. Buy a whole shitload of 10mms and walk into the junkyard jingling. You can lose a ton of them and not even care, as long as you have one left. This is an appealing vision, to be certain. Everyone wants to Be Prepared... but what happens when the curse moves on to your 12mm, something that is needed nearly as often?

Our scientists, with the help of a psychic that we found all by herself in a completely abandoned shopping mall, have determined an even better fix. We arm one volunteer with a chain-mail coat made entirely of ten-millimetre sockets, and walk their ass into the junkyard. They don't do any wrenching, which would cause them to lose their bounty. All they do is walk around, and when they see someone in crisis, break a socket off and hand it to the stricken victim.

There is a downside: any volunteer who does this is struck with so much positive karma that they start getting a little loopy, and create their own death cult right in the middle of the yard. To keep this from happening again, we have to regularly rotate out the volunteers, and put duct tape over their mouths so they can't start spouting the Good Word until a team of engine-pulling weirdos begin to kill in their name. I admit that the system is a little bit unorthodox, but I've never gotten parts pulled faster.

oobh okay so I went and looked at it today. it’s not in bad shape but I can see some problems that may/will need eventual fixing and I’m getting the stark reality check that most cars are Not as cheap to work on as miatas are

I thought it sold but they just relisted it for a hundred dollars less 🫣🫣🫣

Damn truck is in the shop again. The engine was misfiring all over the place, so it's probably my garbage-ass tune-up from last year finally yielding the deserved consequences. Could also be the EVAP system but I really do think it's a tuning issue.

[tussive]

Checked the error codes causing the check engine light to come on in the car and they're all related to the catalytic converter/evap system, so I figure thats' safe to ignore lmao

[hometowne-auto-repair-and-tire]

As we performed check engine light diagnostics on a Lexus ES, we found a code for incorrect purge flow of the evaporative system.

The EVAP system has a purge valve, and the vehicle detects the flow through the valve when it’s commanded to open or close. If the computer doesn’t see what it wants to see, it will trigger a code.

With the scan tool, we should be able to override the car and cause the valve to open or close. The circuitry of the purge valve isn’t responding to the command from the scan tool. There is power and ground, so our technician suggested replacing the purge solenoid and rechecking.

EVAP system issues are among many causes behind a check engine light.

It can be a symptom of an engine misfire and problems with the ignition system, too. Oxygen sensors, catalytic converters, ignition coils and spark plugs are also possible culprits.

evap cooling system

An evap cooling system, also known as an evaporative cooling system, is an energy-efficient method of cooling air by utilizing the natural process of water evaporation. In this system, warm air is passed over water-saturated pads or through water-cooled coils, causing the water to evaporate and absorb heat from the air. As a result, the air temperature drops significantly, creating a cool and fresh atmosphere.

Evap cooling systems are particularly effective in dry, hot climates, where they offer substantial energy savings compared to traditional air conditioning systems. These systems are commonly used in industrial settings, commercial buildings, and even residential applications. Environmentally friendly, evap cooling systems use water and consume less energy, making them an ideal choice for sustainable cooling solutions. They are especially effective in dry climates, offering a more sustainable, cost-effective alternative to traditional air conditioning. Evap cooling systems require less energy and use water instead of chemical refrigerants, making them an ideal choice for both industrial and residential applications.
