Heat pump for use with e.g. heating installation in buildings, has intermediate circuit isolated from exchanger and ensuring transfer of heat between primary output condenser and secondary output evaporator in operational state

摘要

The pump has a primary output condenser (C1) and a secondary input evaporator (E2) that are exchangers between a respective refrigerating fluid and a coolant of an intermediate circuit (9). A tilting unit (V2) tilts between two operational states. The intermediate loop connects the primary output condenser at a utilization exchanger (6) by bordering a primary input evaporator (E1) in one of the operational states. The intermediate circuit is isolated from the exchanger and ensures transfer of heat between the primary condenser and the secondary evaporator in the other operational state.
