The Revolution of Heat Pump Technology

Air source heat pumps use the earth's free ambient energy to produce renewable heat energy for central heating and hot water systems. They were first built in the 1850's with Lord Kelvin suggesting the theory and Peter Ritter von Rittinger building the first example. The modern heat pump can take its energy from water, the air or the ground; with the advancement in condensers and compressor efficiencies making them a major contributor to the micro generation of renewable energy.

Global Energy Systems' Eco Air Boilers are high performance, air source heat pumps, capable of generating energy in a green and highly cost effective manner. They have a COP (Coefficient of Performance) of greater than 1 up to 4 in fact, indicating that they actually generate energy, producing up to 4 times more kW of heat output than kW of electricity consumed. Heat pumps thus reduce fuel bills by up to 65% and carbon emissions by up to 60%.

Heat pumps are, in the simplest terms, a reverse refrigeration cycle of condensation and evaporation of a liquid/gas, with an electric pump compressing the gas to create heat energy. This is the heat that you feel at the back of a domestic fridge with the cold air in this case being dissipated outdoors. A liquid refrigerant that evaporates at -40°C is used, meaning that it can boil even when the air temperature is -25°C.

Air Source

1. Air is drawn in over the evaporator, boiling the liquid refrigerant into a gas. 2. The gas is then compressed by an electric motor to create heat. 3. The heat from the compressed gas is transferred to your home heating system through the heat exchanger 4.Having been through the heat exchanger and having given up its heat, the gas returns to a liquid state and enters the expansion valve where it is re-cycled through the system and the process is repeated.

 





This diagram demonstrates the effect on temperature of increasing the pressure of a gas. With the step from 2 -3 being the extraction of the energy to heat the water in the Eco Store Hot Water Tank.

The electrical energy applied to the compressor is as little as 25% of that generated in heat. This is the essence of the high performance, renewable technology that Global Energy Systems has developed.

This is micro generation, one of the key elements of the Government's carbon reduction plan.
