The invention relates to an integrated heat pump capable of achieving refrigeration and heating switching based on motor-driven three-way valves and belongs to the field of energy saving and environmental protection. The heat pump comprises an integrated heat pump unit main body formed by a condenser and an evaporator, a condenser inlet connection pipeline and a condenser outlet connection pipeline which are connected with the condenser, an evaporator inlet connection pipeline and an evaporator outlet connection pipeline which are connected with an evaporator, four motor-driven three-way valves, a control wire and a motor-driven valve controller arranged in a control cabinet, wherein the condenser inlet connection pipeline is communicated with an evaporator inlet and a condenser inlet through a motor-driven valve, the condenser outlet connection pipeline is communicated with a condenser outlet and an evaporator outlet through the motor-driven three-way valves, the evaporator outlet connection pipeline is communicated with the evaporator outlet and the condenser outlet through the motor-driven three-way valves, and the evaporator inlet connection pipeline is communicated with the evaporator inlet and the condenser inlet through the motor-driven three-way valve. The heat pump is compact in structure, low in fault rate and good in use effect.
Description
technical field [0001] The invention belongs to the technical field of energy saving and environmental protection, and in particular relates to a large electric drive heat pump unit. Background technique [0002] Heat pump technology has been developed in my country for many years, and it has been tepid. Recently, with the country's emphasis on energy conservation and environmental protection, the development of heat pumps has become more rapid. Heat pumps are divided into electric drive and thermal drive according to the drive mode. Generally, those with cooling capacity less than or equal to 60kW are small heat pump units, and those with cooling capacity greater than 60kW are large heat pump units. In electric-driven small and medium-sized heat pump units, the switching between cooling and heating is realized through the four-way reversing valve in the fluorine system; if the large-scale heat pump unit also realizes the switching between cooling and heating through the fo...
