Performance up to COP 10 with EnergyMachines™ optimal heat exchanger technology
EnergyMachines™ is the result of many years of Research and Development. Its integrated energy system is based on the same technology as a heat exchanger, efficiently extracting energy from the hot temperature liquid to pre-heat domestic hot water. The result is a high performance energy exchange.

A heat pump extracts heat from a relatively low-temperature area (for example the ground energy from a high temperature area) and adds mechanical energy, transferring to low-temperature area (for example outdoor air).

COP measures the performance of cooling units and heat pumps

The coefficient of performance (COP) is used to compare the performance of cooling units and heat pumps. COP describes the ratio between the transported thermal energy and the added mechanical energy. A heat pump which lifts the thermal energy from 0° C to 60° C has a COP factor of 2,5. This means that the thermal energy is 2,5 times higher than the mechanical energy input. If the heat pump lifts the thermal energy from 0° C to 30° C, it has a COP factor of 5.

Heat exchangers working in both directions provide a higher COP

Commercial real estate buildings often have a simultaneous demand for heating and cooling. The cooling demand can be satisfied by producing water of 10° C and heat demand by producing water of 40° C. When both the cold and hot sides of a heat exchanger are used at the same time, the amount of the thermal energy doubles in relation to the applied mechanical energy. This gives COP 10.

EnergyMachines™ use waste heat to increase performance

EnergyMachines™ integrated energy system uses sub-cooling technology resulting in a performance increase of 30-50%, compared to conventional heat pumps. More performance is achieved both in hot water production as well as in heat demand, reaching temperatures between 45 and 60° C.
