A brine/water heat pump system has two separated circulation circuits connected through a heat exchanger providing heating and cooling without a mixer circuit

摘要

One circuit (K1) has a pump (20), an underground coil (10), evaporator (130) and control valve (30). The second circuit (K2) has a pump (90), a room heater/cooler (50) and condenser (100) with a valve (60) by which excess heat is diverted to a tank (70). The circuits are connected through a heat exchanger (40).
