Three function heat pump system with one way receiver

摘要: The invention relates to a three function heat pump system which provides space heating, cooling and hot water production. permits production all year long without operation of the in heating or modes. also check valve arrangement allows passage refrigerant through receiver modes reversing flow receiver. valving prevents migration from liquid thermal storage tank during mode. In addition, pass throttle expansion valves when is passing outdoor air coil, while bypassing passes coil inlet.
