The heat pump system comprises a low-temperature reactor, a four-way control valve, a compressor, a high-temperature reactor and a valve, wherein a low-temperature reactor hydrogen interface III of the low-temperature reactor is connected with a four-way control valve hydrogen interface I of the four-way control valve, a four-way control valve hydrogen interface II of the four-way control valve is connected with a compressor hydrogen inlet of the compressor, a compressor hydrogen outlet of the compressor is connected with a four-way control valve hydrogen interface III of the four-way control valve, a four-way control valve hydrogen interface IV of the four-way control valve is connected with a high-temperature reactor hydrogen interface III of the high-temperature reactor, a high-temperature reactor hydrogen interface IV of the high-temperature reactor is connected with a low-temperature reactor hydrogen interface IV of the low-temperature reactor through the valve, and the low-temperature reactor and the high-temperature reactor contain different metal hydride respectively.

Description

technical field [0001] The invention relates to the technical field of refrigeration and air-conditioning equipment, in particular to a combined-driven metal hydride heat pump system. Background technique [0002] Metal hydride is a new type of functional metal material, which can reversibly release and absorb a large amount of hydrogen at a certain temperature and pressure, accompanied by a huge enthalpy change, so it can be used to construct a metal hydride heat pump system to achieve low-temperature refrigeration and high-temperature heating and other functions, and has the characteristics of environmental friendliness and low-grade energy utilization. It is a hot spot for research and development in the world. [0003] In the prior art, metal hydride heat pumps can be divided into two types according to the driving mode: heat-driven metal hydride heat pump systems (MHHP) and compressor-driven metal hydride heat pump systems (CDMHHP). [0004] The heat-driven metal hydri...
