Heat pump systems

The use of various heat pumps and chillers (e.g. domestic split air conditioners, liquid chillers) is rapidly expanding. Heat pumps usually use electricity to pump thermal energy from a colder medium (e.g. air in winter, soil, groundwater) to a warmer medium (e.g. the heating circuit of a residential building or directly heated air space). As the amount of thermal energy extracted can be up to 3-7 times the amount of electricity used, heat pump energy production is usually classified as renewable energy.

Refrigeration works on the same principle, but the emphasis is on the cooling side. A wide range of technical solutions is available on the market, from domestic scale to industrial applications.

The efficiency of a heat pump system, i.e. the ratio between the thermal energy delivered and the electricity used, is highly dependent on the operating parameters, so the competent design of concepts is a key issue that can have a profound impact on the subsequent operating costs. In some cases, it has to be accepted that it is not economically viable to use a heat pump for a given demand. On the other hand, in specific cases where, for example, heating and cooling energy needs are present in the installation at the same time, the use of a common heat pump can be very efficient.

We jointly undertake feasibility studies for heat pump and refrigeration systems, technical concepts supported by economic calculations, feasibility studies, complete design, and technical supervision during implementation.
