Heat pump device for temperature regulation and ventilation of a locale

摘要

Heat pump device for temperature regulation and ventilation of a locale. The device comprises a cooling medium circuit (1), whose condenser (H1) is in thermal-transmitting contact with the airflow in a supply air unit (2) and whose evaporator (H2) is in thermal-transmitting contact with the extract air from the locale. The condenser (H1) is situated in a flow device (16) with bypass line (20) that is housed in the supply air unit (2). A separate damper is used to divide the total supply air between the condenser (H1) and the bypass line (20) so that the condenser temperature is maintained at the desired level so the heat pump can work with great efficiency under various operation conditions.
