Geothermal Heat Pump System Diagram

When the heat pump is in heating mode the hot vapor is directed to the coil in the indoor airstream.

Geothermal heat pump system diagram.

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. As hot vapor leaves the compressor it approaches the reversing valve. Note the refrigerant flow in the diagram. Unlike geothermal systems of the past our closed loop system actually are open loop non pressurized.

The pump station will automatically remove the air from the piping and makes commissioning a system so much easier. A desuperheater does not affect the heat output of the geothermal system in the winter. The underground pipes called a ground loop circulate water which absorbs the heat from the earth and returns it to the indoor heat pump. 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.

Geothermal systems make hot water in both heating mode and air conditioning mode. Two pieces to the geothermal system. Ground loop system of fluid filled plastic pipes buried in the shallow ground or placed in a body of water near the building. 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. Heat pump the inside unit known as the heat pump. Istockphoto s 117086265 and 12333446 continued a dual source heat pump combines an ashp with a geothermal heat pump. The water piped through this loop uses soil temperature to warm or cool.

For water heating you can add a desuperheater to a geothermal heat pump system. Water source heat pump systems generally require smaller mechanical rooms than other hvac systems. Ground loop underground pipes which connect to the heat pump. The basic elements of a geothermal heat pump system include.

Geothermal heat pump diagrams illustrates the difference between a house with a standard heat pump and one with the geothermal heating and cooling. In this situation the heat pump draws heat from the geothermal water and heats the home. This makes installation much simpler. The biggest difference is the absence of an exterior or outdoor compressor.

The heart of a typical geothermal system is a ground source heat pump that cycles water through an underground piping loop. A desuperheater is an auxiliary heat exchanger that uses superheated gases from the heat pump s.
