AusGeothermal Reverse Cycle Heat Pump Units

For heating and cooling via air ducts with the option of an additional hot water supply.

AusGeothermal heat pumps are manufactured using the highest quality parts and latest technology, such as high efficiency Copeland scroll compressors, coupled with ozone friendly R410a refrigerant.

• Single phase 240v, 50 Hz units can be supplied in a range of capacities from 5-20kw. Our 18-20kw unit is very popular with clients who do not have natural gas and have single phase power supply. Soft starters are used to reduce current draw on unit start up

AusGeothermal Heat Pump – How this works for heating your home or business

AusGeothermal heat pump units are a direct exchange refrigeration system using R410A refrigerant to transfer heat from one place to another.

In the heating cycle:

• Refrigerant enters the ground loop coils as a high pressure liquid
• The refrigerant passes through an expansion device which causes instant pressure and the temperature of the liquid to drop
• The liquid passes through the ground loops, absorbing heat from the surrounding earth, which causes refrigerant to boil off and change state into a vapour form.
• This vapour is now a useable substance to be re-compressed into a high pressure/high temperature vapour by the system’s compressor.

The refrigerant is then used to heat your premises via a fan coil unit. Heat is transferred into the air passing over the copper finned coil and then distributed by ducting to heat your home.

While this is happening, refrigerant in the copper finned coil is changing state and condensing from a high pressure vapour to a high pressure/low temperature liquid. This liquid is re-directed to the ground coils to begin the cycle over.

AusGeothermal Heat Pump – How this works in cooling your home or business

In cooling mode the refrigeration cycle is reversed, meaning liquid refrigerant now enters the ducted fan coil unit via a refrigerant expansion device.

• As high pressure liquid passes through this device it creates a sudden pressure and temperature drop in the refrigerant. The heat from your premises now passes over the copper finned evaporator coil.
• Heat is absorbed into the refrigerant, creating cooler supply air and a change of state of this refrigerant.
• The heat absorbed into the refrigerant is now transferred into the ground loops via the systems compressor.
• Refrigerant passing through the ground loops is now dispensing heat into the earth causing a re-condensing effect in the refrigerant for the cycle to begin over.

Geothermal hot water production – How this works

By using AusGeothermal heat pumps hot water can be produced via a plate heat exchanger, which is mounted in the unit.

The heat exchanger works by transferring heat from discharge refrigerant super heated by the system’s compressor through a set of copper and stainless steel plates. Water passes over the opposite side of these plates absorbing heat and re-circulating back to your sanitary hot water cylinder or via hydronic heating.

When the system is being used for heating or cooling, HOT WATER CAN BE PRODUCED FOR FREE.
