Our common future needs new technologies
Heat pumps transfer low-temperature heat from the environment and waste heat from industrial processes as useful heat at a higher temperature level to a system to be heated. A heat pump has a primary and a secondary circuit. Heat is transferred from the primary to the secondary circuit via two heat exchangers by a refrigerant circulating in the heat pump.
The primary circuit is the circuit that brings the thermal energy into the heat pump and heats the refrigerant via a heat exchanger.
In the secondary circuit, the heat stored in the refrigerant is transferred via a heat exchanger to the medium circulating in the secondary circuit.
Large heat pump (LHP)
Large heat pumps can transmit outputs of several MW.
Large heat pumps from approx. 2 MW are custom-made products that are specially designed and manufactured to meet the requirements of the application. In many projects, the large heat pump is part of an overall system, such as in a district heating network, in combination with combined heat and power plants or P2H processes.
Due to the project-speciﬁc requirements when using large heat pumps, timely and detailed planning is necessary. This applies not only to the design of the large heat pump, but also to the planning of the primary and secondary circuits of the entire system.
