What Is a Heat Pump Condenser?
A Guide to Heat Pump Condensers and How They Work
In places like Palm Desert where the winter weather is usually relatively mild, heat pumps are definitely the best way to heat your home and will use far less energy than any other heating option. Another major advantage of a heat pump is that the unit will also function as an air conditioner to keep your home cool. The heat pump condenser is the most important component of this type of system, and here is a quick overview of exactly what the condenser is and how it works.
What Is a Heat Pump Condenser?
Both heat pumps and traditional air conditioning systems have a condenser, and this is simply the name given to the unit that sits outside the house. The heat pump condenser is the primary component of the system, and it looks almost exactly the same as an AC condenser. The two units also function in the same way when cooling.
Both heat pump condensers and AC condensers cool by removing heat from the building and releasing it outside. The difference between the two is that a heat pump can run in reverse to absorb heat from outside and transfer it into the home.
How Does a Heat Pump Condenser Work?
Just like a central AC unit, a heat pump works in conjunction with the evaporator coil and air handler inside the building. The way that a heat pump functions is different depending on whether it is heating or cooling.
When cooling, the condenser compresses the refrigerant in the system into a cold liquid. It pumps this liquid through a copper line and into the evaporator coil. The HVAC fan sucks hot air into the ductwork and blows it over the coil. This causes all of the heat energy in the air to flow into the refrigerant and almost instantly cools the air. Finally, the cold air is circulated throughout the building and the hot refrigerant is pumped outside where the fan in the heat pump helps to disperse all of the heat back into the air outside.
When you switch the system to heating, the heat pump activates its reversing valve so that the refrigerant flows in the opposite direction. The process still starts by compressing the refrigerant into a cold liquid. However, instead of pumping the liquid inside as when cooling, the refrigerant instead flows into the coil in the outdoor heat pump condenser. The unit’s fan blows air over the coil, and any heat energy in the air is naturally absorbed by the cold refrigerant. This process quickly raises the temperature of the refrigerant and transforms it into a hot gas. The gas is then pumped into the indoor coil, and cold air is forced over the coil so that all of the heat energy transfers from the refrigerant into the air.
Why Heat Pumps Are Perfect for Warmer Climates
The process of capturing heat from the air in one place and using it to heat or cool the air in another is known as heat transfer, and this is what makes heat pumps so energy efficient. Electric furnaces and other types of electric heating have a one-to-one efficiency ratio, i.e. 100%. This means that every unit of electricity the unit uses is converted into a unit of heat energy. Gas furnaces aren’t even that efficient; even the very best unit will have a maximum efficiency of 98.5%.
Due to the nature of the heat transfer process, the efficiency ratio of a heat pump is typically two-to-one or even three-to-one, meaning that for every unit of electricity consumed, two or three units of heat energy are produced. The only issue is that the efficiency of a heat pump decreases as the outdoor air temperature drops. They can technically work in below-freezing temperatures as the air always contains at least some heat energy.
Still, heat pumps always work best and most efficiently when the outdoor temperature is at least 40 degrees or more. This makes them the perfect choice for Palm Desert and other warmer climates. Compared to any other type of electric or gas heating, the energy costs of using a heat pump can be anywhere from 30% to 60% lower. A heat pump will also be far cheaper than purchasing and installing separate cooling and heating systems, which is yet another reason why they’re such a fantastic choice.
