ABSTRACT:
Disclosed is a multipurpose heat pump system including a heat pump unit using air as a heat source, a heat recovery heat exchanger, and a heat storage. Refrigerant in the heat pump unit can be guided to flow through different paths defined by a four-way valve of the heat pump unit, so that the heat pump unit can operate in different modes depending on actual needs to produce cold/hot water for air conditioning and/or hot water for daily use. Heat generated during a refrigerant compression in the heat pump unit can be recovered for heating water in the heat storage. Stratified hot water is stored in the heat storage and can be supplied for daily use.
