What Does Chw Stand For In Hvac?

Are you new to the HVAC industry and wondering what all these acronyms mean? Well, today we’re going to dive into one of the most important ones: CHW. You may have heard it tossed around in conversations or seen it on job listings, but what does CHW actually stand for and why is it so crucial in HVAC systems? Get ready to learn everything you need to know about CHW!

What Does Chw Stand For In Hvac?

Chilled water air conditioning (chwAC) systems use a chilled water reservoir and pump to distribute cold, ambient air throughout the system.

The Different Types of Carburetors

There are a few different types of carburetors, all with their own specific functions. Here’s a look at the most common ones:

1. Manual-style carburetors: These require you to manually adjust the fuel mixture as you go. They’re generally favored by enthusiasts because they offer more control over the engine’s make and break.

2. Dual-fuel carburetors: These can use either gasoline or ethanol, which makes them useful for vehicles that are required to mix both fuels together.

3. Fuel injection: This is the most common type of carburetor today, and it uses tiny jets to force the fuel into the engine. It offers improved performance and fuel economy compared to other carburetors.

How to Maintain Your Hvac System

One of the most important things you can do to keep your heating and cooling system in good working order is to maintain it. Here are some tips on how to do that:

1) Regularly check the air filters. If they’re dirty, replace them as soon as possible. Failing to clean the filters will cause your system to work harder, which could lead to problems down the line.

2) Check the registers and valves for obstructions or leaks. If there’s something blocking or leaking, it’ll require periodic repairs or replacements to keep your system running smoothly.

3) Change the furnace filter every six months and the HVAC unit filter every year. These filters help remove dust, pollen, and other allergens from the air, which in turn helped reduce respiratory problems in people living in close quarters with smokers.

4) Make sure all cables are properly secured and disconnected when not in use. This will prevent them from becoming tangled and creating a hazard.

5) Be sure to register your HVAC unit with your municipality if you live in an urban area. This will let officials know if there are any issues with your system that need to be fixed right away.


Chw stands for “chiller water.” Chiller water is a water used in the HVAC industry to cool down rooms. The colder the room, the better it will perform because it causes less heat loss.
