Geothermal Heat Pump System Diagram

Heat pump the inside unit known as the heat pump.

Geothermal heat pump system diagram. Geothermal heat pump systems also provide excellent zone space conditioning allowing different parts of the home to be heated or cooled to different temperatures. The basic elements of a geothermal heat pump system include. A desuperheater is an auxiliary heat exchanger that uses superheated gases from the heat pump s. It is merely a pump and a heat exchanger that is plumbed in such a way so as to carry the waste heat away from the refrigeration cycle and into your water heater.

Ground loop underground pipes which connect to the heat pump. Geothermal systems make hot water in both heating mode and air conditioning mode. Geothermal system mechanical rooms are even smaller requiring space for only the circulating pumps the main header and some chemical treatment equipment. As hot vapor leaves the compressor it approaches the reversing valve.

Istockphoto s 117086265 and 12333446 continued a dual source heat pump combines an ashp with a geothermal heat pump. Note the refrigerant flow in the diagram. The biggest difference is the absence of an exterior or outdoor compressor. Unlike geothermal systems of the past our closed loop system actually are open loop non pressurized.

The water piped through this loop uses soil temperature to warm or cool. When the heat pump is in heating mode the hot vapor is directed to the coil in the indoor airstream. This makes installation much simpler. In this situation the heat pump draws heat from the geothermal water and heats the home.

Ground loop system of fluid filled plastic pipes buried in the shallow ground or placed in a body of water near the building. Two pieces to the geothermal system. Geothermal heat pump diagrams illustrates the difference between a house with a standard heat pump and one with the geothermal heating and cooling. A desuperheater does not affect the heat output of the geothermal system in the winter.

How does a geothermal unit produce heating cooling and most of our hot water as well here is a heating cycle diagram here is a cooling cycle diagram. The heat pump extracts the. Water source heat pump systems generally require smaller mechanical rooms than other hvac systems. The pump station will automatically remove the air from the piping and makes commissioning a system so much easier.

Geothermal heat pump systems consisting of the heat exchanger left and the heat pump right heat and cool a home by transferring heat to and from the earth. The heart of a typical geothermal system is a ground source heat pump that cycles water through an underground piping loop.
