As an Australian homeowner, you may have heard of air source heat pump water heaters and wondered what types of evaporators they use. Well, the good news is that there are several different types of evaporators used in these types of water heaters. In this article, we’ll explain what these evaporators are and how they work.
First off, let’s start by explaining what an evaporator is. An evaporator is a device that absorbs energy from the air and uses it to heat liquid or gas. This energy can be used to provide hot water for your home or business. Heat pumps use a compressor to transfer the energy from the outside air into the liquid or gas inside the evaporator. The evaporator then turns this energy into hot water for your home or business.
The most common type of evaporator used in air source heat pump water heaters is a flooded evaporator. This type of evaporator uses a small amount of refrigerant to absorb energy from the outside air and transfer it into a liquid form inside a sealed container. The liquid then passes through an expansion valve where it vaporizes, releasing energy in the form of hot water which is then circulated throughout your home or business.
Another type of evaporator used in air source heat pump water heaters is an open loop system. This type works similarly to a flooded system but with one main difference – instead of using refrigerant, it uses air as its medium for transferring energy from the outside into the liquid contained within the system’s coils or tubes. This means that there are no refrigerants involved which makes this system more efficient and cost-effective compared to other types of systems.
Finally, there’s also the direct expansion (DX) system which uses heated refrigerant directly to absorb energy from outside air and transfer it into a liquid form inside its coils or tubes within the system’s housing unit. While this type does require more maintenance than other systems due to its reliance on refrigerants, it provides more efficient and powerful performance overall compared to other systems available on the market today.
So there you have it – those are some of the different types of evaporators used in air source heat pump water heaters! Each one has its own benefits and drawbacks so make sure you do your research before making your decision on which one would be best for your needs!
