Heating and Cooling Provided by Heat Pumps
Many homeowners use heat pumps to heat and cool their homes. With just a single unit, homeowners will receive heating and air conditioning. However, some heat pump owners know only a few of the details about how heat pump units perform both the jobs of an air conditioner and a heater.
A heat pump is not a combo unit that packages the two systems together. A heat pump uses the same method to provide heating as well as cooling. Below are a few hints to help you understanding how heat pumps work.
If you need repairs performed on your current heat pump, or if you are interested in having a heat pump installed in your home, call Heating Cooling Chapel Hill.
Heat exchange and Heat Pumps
Heat pumps operate through what is called heat exchange, and they neither create heat nor cold. Instead, heat exchange simply moves the heat from one location of your home to another. If you pull out the existing heat from a room, the room will feel cooler. If you bring the heat back into the room, it will then feel warmer. A heat pump is constructed so that it moves the available heat to whatever room you need it in the most. In the summer, you want the heat removed to the outside. In the winter, you will want the heat kept inside.
Here is how the heat pump performs this function. Your heat pump is made up of two units, an indoor unit and an outdoor unit. Flowing between these two units and along the copper lines is a chemical mixture known as a refrigerant, which easily changes between a liquid and a gaseous state.
The refrigerant simply absorbs heat from an evaporator coil located in one of the two units, and then moves it to a compressor, which squeezes the refrigerant into a high-pressure, high-temperature gas. The refrigerant will then move to the condenser coil, where it will release the heat. After releasing the heat, the refrigerant will then travel back to the condenser coil to restart the cycle over again.
During cooling cycle, the indoor coil will act as an evaporator and absorb the heat in your home. When the heat pump goes into heating mode, the reversing valve changes the direction in which the refrigerant flows. Now, the indoor coil will act as the condenser, and releasing heat outdoors.
