What Is A Geothermal Heat Pump?
Geothermal heat pumps, also known as ground source heat pumps (GSHPs), are HVAC systems that utilize the Earth’s consistent temperature as a heating and cooling source. They tap into the thermal energy stored in the ground to provide efficient temperature control for residential and commercial spaces.
Unlike traditional heating and cooling methods that rely on fossil fuels, the best geothermal heat pump is highly energy-efficient and environmentally friendly.
How Does A Geothermal Heat Pump Work?
A carrier geothermal heat pump utilizes the Earth’s heat, which remains relatively constant below the frost line. The system consists of three main components: the ground loop, heat pump unit, and air delivery system.
Here’s how it works:
1. Ground Loop
A network of pipes, typically filled with a mixture of water and antifreeze, is buried underground. This loop absorbs heat from the ground during the heating season and releases heat into the ground during the cooling season.
2. Heat Pump Unit
The heat pump unit, located indoors, contains a compressor, evaporator, and condenser. During the heating season, the heat pump extracts heat from the ground loop and transfers it indoors. During the cooling season, the process is reversed, and heat is extracted from the indoor air and transferred to the ground loop.
3. Air Delivery System
A forced air distribution system or radiant floor system delivers heated or cooled air to different areas of the home.
