Heat Pumps: The mystery of how it extracts warmth from the chilly air outside
A heat pump brings air from the outside of the house and extracts the heat. (Interestingly, there is a decent amount of heat to be obtained from outdoors.) This process can continue until the outdoor air gets to approximately 30 to 35 degrees F. An actual heater will need to be used when you get to this low temperature. When it’s cold outside the pump will extract the outside heat and transfer it inside. Meanwhile, if it’s warm outside, it reverses directions and acts like an air conditioner, removing heat from your home. One advantage of a heat pump is that it moves heat instead of generating heat, giving you more energy efficiency.
A heat pump is the opposite of an air conditioner. But, what exactly is a heat pump? Is it an air conditioner in reverse? With an air conditioner, heat is taken from the home or office and pushed into refrigerant inside the fan in your basement or closet. The coolant carries the heat to an outdoor unit where it is transferred thereby leaving the cooler air inside the building. This same cycle happens millions of times an hour in American refrigerators and freezers.
What if Your Area Drops Below Freezing?
For climates that don’t get below freezing, like much of the desert in and around Topock, Arizona, a heat pump is an excellent solution. A geo-exchange (geothermal) heat pump might be a better heat pump choice in colder climates. In this system, a pipe is buried underground and has antifreeze running through it. This method replaces the outdoor air conditioning unit. Since it is underground the air always flows thru the earth’s 52 degrees F. Initially, The cost is dramatically higher because of drilling, but it works much better in cold weather.
