The membrane separation and heat drive combined absorption type heat pump comprises a membrane separation device, an isobaric exchange type energy recovery device, a heat drive generator and the like. The membrane separation device is connected to an absorber through the isobaric exchange type energy recovery device. The absorber is returned into the membrane separation device through the isobaric exchange type energy recovery device. The heat drive generator is connected to the absorber sequentially through a condenser and an evaporator. The absorber is returned into the membrane separation device through a solution boosting pump. According to the structure, a refrigerating device for combining the membrane separation, the heat drive and the energy recovery is designed, after an absorption type solution is subjected to efficient primary non-phase-change separation through a reverse osmosis membrane separation technology at the low-concentration section, then gas-liquid separation is conducted through the heat drive generator, the heating amount required by the following gas-liquid separation and the cooling amount of liquid condensed by the following gas are reduced greatly in the primary non-phase-change separation process, the energy is saved greatly, and the membrane separation and heat drive combined absorption type heat pump has the great energy-saving potential.

[0002] In the past hundred years, refrigeration equipment has been evolving around the electric compression refrigeration cycle and absorption refrigeration cycle. The electric compression refrigeration cycle has developed high-efficiency equipment related to magnetic levitation centrifugal type this year, while the absorption refrigeration equipment has not made breakthroughs. Technological improvement, reverse osmosis membrane technology has made great progress in the past 50 years; reverse osmosis membrane has excellent separation selectivity, and there is a gas-liquid separation or liquid-liquid separation process in the absorption refrigeration cycle; so membrane separation technology is in the absorption However, at the same time, membrane separation requires high working pressure, and its separation efficiency is affected by solution concentration and temperature. In the past, there were some defects in the use of membrane separation absorption heat pumps. Membrane separation technology is not yet mature in structure, and there are some flaws in the design of technical principles. The energy is not fully utilized, which is easy to cause energy loss and refrigeration effect.
