Geothermal Heat Pump System Diagram

Unlike geothermal systems of the past our closed loop system actually are open loop non pressurized.

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 geothermal heat pump system can be used for both heating and cooling. All you need is piping from the heat pump to your water source and a trench to bury it in.

Heat pumps are available with heating capacities of less than 3 kilowatts kw to over 1 500 kw. With an open loop system you simply draw water from the water source run it through your heat pump and pump it back to the source. 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 water piped through this loop uses soil temperature to warm or cool.

Since the ground and air outside always contain some heat a heat pump can supply heat to a house even on cold winter days. This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational. With an open loop system there is no need for expensive geothermal drilling rigs and a lot of piping. In fact air at 18 c contains about 85 percent.

The types of heat pumps that are adaptable to geothermal energy are water to air and water to water. The basic elements of a geothermal heat pump system include. A geothermal heat pump ghp or ground source heat pump gshp is a central heating and or cooling system that transfers heat to or from the ground. It uses the earth all the time without any intermittency as a heat source in the winter or a heat sink in the summer.

The heat pump cycle is fully reversible and heat pumps can provide year round climate control for your home heating in winter and cooling and dehumidifying in summer. Geothermal heat pump diagrams illustrates the difference between a house with a standard heat pump and one with the geothermal heating and cooling.
