In Knoxville, heat pumps can be a popular option for heating and cooling your house.
They appear very similar to an air conditioner. In reality, they operate in the same way during the summer. Since they have a reversing valve, they can shift humidity in the opposite direction as well as add comfort to your house when it's cold.
Not sure if you rely on a heat pump or an air conditioner? Simply locate the model number on the outdoor unit and look it up online. If you discover you own a heat pump, or you’re thinking over purchasing one, learn more about how this HVAC system keeps homes comfy.
How Heat Pumps Operate
Heat pumps rely on a refrigeration system like an air conditioner. Most can run similar to a ductless mini-split, because they can heat and cool. Heat pumps rely on an indoor evaporator coil and an outdoor condensing coil. Refrigerant is pumped through these coils to shift warmth. The outdoor unit also has a compressor and is enclosed by metal fins that act as a heat sink to help move heat efficiently.
In cooling mode, the refrigerant starts in the evaporator coil. Air from indoors moves over the coil, and the refrigerant sucks out heat. Water in the air also condenses on the coil, dropping into the condensate pan below and drains away. The resulting dehumidified air flows through the ductwork and back into your house.
Meanwhile, the refrigerant flows a compressor on its way to the outdoor coil. This constricts the refrigerant, forcing it to heat up even more. As it goes through the condensing coil, the outdoor fan and metal fins help to emit heat to the outdoors. The refrigerant travels back into your house, passing through an expansion valve that chills it considerably, readying it to go through the process all over again.
When your heat pump is installed and maintained correctly, you’ll have efficient cooling comparable to a high-performance air conditioner.
When your heat pump is heating, the heat exchange cycle occurs the opposite way. By moving in the opposing direction, refrigerant removes heat from the outdoor air and vents it into your home to warm the interior.
Heat pumps running in heating mode are most useful when the temperature is above freezing outside. If it turns too chilly, a backup electric resistance heater turns on to keep your house comfy, but your heating costs go up as a result.
Heat pumps work longer than furnaces since the air doesn’t get as warm. This helps maintain a more stable indoor temperature. Additionally, because heat pumps move warmth rather than making it from a fuel source, they can operate well above 100% efficiency. You should expect 30–40% savings on your heating bills by using a heat pump.
