Geothermal Heat Pumps for Efficient Heating & Cooling

Ground source heat pumps are also known as geothermal heat pumps. This conditioning system relies on a geothermal source. It could be groundwater or surface water. This conditioning system uses a reversible cooling cycle to heat or cool. You can now find the best reverse cycle air conditioner in Melbourne via

A heat sink is also used to transfer heat. The conditioning system functions in the same way as an air source heat pump: it uses both compressors to circulate refrigerant within a closed-loop to transfer heat from an indoor to another coil, where heat is either absorbed or rejected.

Geothermal heat pumps, unlike the air source heat pump, use a geothermal source and sink. The temperature of the earth is not affected by the ambient air used in air source models. Its temperature ranges from five to ten inches below the surface. This makes the earth a more efficient heat source for heat pumps. This heat source is also cooler than outdoor and warmer in winter. This is more efficient than an air source type conditioning system.

This type of conditioning system can be of many types. A hybrid system uses multiple geothermal resources or outdoor air. If your cooling requirements are greater than your heating needs, a hybrid system can be very helpful.

The standing column well is another option for this type of conditioning system. This system uses an open loop variation. A number of deep vertical wells can be drilled. Water is then drawn from the bottom and returned to the top.
