Title: A HEAT PUMP APPARATUS WITH ENERGY RECOVERY
Abstract:
Gas compression heat pump for heating and cooling, comprising a main circuit operating with a heat transfer fluid, wherein the main circuit includes at least one user heat exchange unit (10), at least one outdoor heat source (21, 22), at least one compression unit (MC) and at least one expansion unit (VE), and valve devices (RM1,..., RM11; EV1,... EV4) for switching the main circuit between a heating configuration and a cooling configuration. The heat pump further comprises an energy recovery circuit (30) operating with water, wherein the energy recovery circuit includes a thermal flywheel (ACT) and is thermally coupled to the main circuit through a heat exchange assembly (40), the heat exchange assembly being adapted on the one hand to transfer heat from the condensed or condensing heat transfer fluid to the water of the energy recovery circuit (30), and on the other hand to transfer heat from the water heated in this way to the evaporating heat transfer fluid.
