How Does a Heat Pump Cool?

Heat pumps are very popular HVAC systems in our area for a few reasons, but it can be confusing how this system can effectively cool your home in Port Neches, TX. The name can be a bit confusing because it makes it sound like the device pumps heat. What it actually does is transfer heat. If you are considering a heat pump for your home, or have one that needs servicing, give the experts at Air Services Unlimited a call.

How It Works

As stated above, a heat pump works by transferring heat from one location to another. This is the same action a refrigerator or air conditioner does, but the fact that a heat pump can also heat makes it a little bit different. Like air conditioners, heat pumps use refrigerant to facilitate the transfer of heat. In the summer the heat pump absorbs the heat in your surrounding air and transfers it to the outdoors and releases it; during the winter months, the heat pump absorbs the heat in the surrounding outdoor air, concentrates it, then warms your home with it.

The reason a heat pump can both heat and cool your home is thanks to a component called the reversing valve. This cylindrical, sliding valve changes the direction in which the refrigerant in the system flows. One direction means heating, the other means cooling. The direction will depend on how the manufacturer produced the valve.

Benefits a Heat Pump Can Offer

  • Great energy efficiency – because heat pumps transfer heat to both heat and cool, very little energy is used, making them very energy efficient

 

  • They are very clean to operate – heat pumps do not use any kind of combustion or combustible fuel to run, so their operation is very clean

 

  • Longer life cycle – Heat pumps typically last 15 years with regular maintenance, versus 10-12 for the average air conditioner
