As hot vapor leaves the compressor it approaches the reversing valve.
Geothermal heat pump system diagram.
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 biggest difference is the absence of an exterior or outdoor compressor.
The underground pipes called a ground loop circulate water which absorbs the heat from the earth and returns it to the indoor heat pump.
In this situation the heat pump draws heat from the geothermal water and heats the home.
Ground loop underground pipes which connect to the heat pump.
The basic elements of a geothermal heat pump system include.
Geothermal system mechanical rooms are even smaller requiring space for only the circulating pumps the main header and some chemical treatment equipment.
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.
A desuperheater is an auxiliary heat exchanger that uses superheated gases from the heat pump s.
Istockphoto s 117086265 and 12333446 continued a dual source heat pump combines an ashp with a geothermal heat pump.
Heat pump the inside unit known as the heat pump.
The heat pump extracts the.
Geothermal heat pump diagrams illustrates the difference between a house with a standard heat pump and one with the geothermal heating and cooling.
For water heating you can add a desuperheater to a geothermal heat pump system.
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.
Water source heat pump systems generally require smaller mechanical rooms than other hvac systems.
Geothermal heat pump systems also provide excellent zone space conditioning allowing different parts of the home to be heated or cooled to different temperatures.
This frees up more useable leasable space for tenants or occupants.
When the heat pump is in heating mode the hot vapor is directed to the coil in the indoor airstream.
The pump station will automatically remove the air from the piping and makes commissioning a system so much easier.
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.
Note the refrigerant flow in the diagram.
A desuperheater does not affect the heat output of the geothermal system in the winter.
The heart of a typical geothermal system is a ground source heat pump that cycles water through an underground piping loop.
Two pieces to the geothermal system.
