The invention discloses a mixed refrigerant applicable to large-circulation temperature rise for a medium-high temperature heat pump. The mixed refrigerant comprises, by mass, 1-10% of HC1270, 2-96% of HFC134a and 3-97% of HCFC 142b. The refrigerant suitably serves as a refrigerant for a medium-high temperature heat pump system with circular temperature rise (temperature difference between evaporation and condensation) of 60-80 DEG C and the condensation temperature of 70-100 DEG C. The refrigerant is low in ozone depletion potential and greenhouse effect potential so as to meet environmental protection requirements, and is appropriate in thermal parameters and excellent in cycling performance, an HFC134a air condition compressor can be used for optimized design of a medium-high temperature heat pump unit in large-circulation temperature rise of the novel refrigerant, and the novel refrigerant can be directly applied to an original HFC134a air conditioning unit to convert the original air conditioning unit into the medium-high temperature heat pump unit in large-circulation temperature rise of the novel refrigerant. The unit can directly use normal-temperature water sources and ground sources at the temperature of about 10-40 DEG C and can provide hot water at the temperature of about 70-100 DEG C for users.

The invention provides an efficient moisture absorption-thermal chemical reaction single-stage thermode driven by low-grade heat energy. According to the efficient moisture absorption-thermal chemical reaction single-stage thermode driven by low-grade heat energy, a reaction bed valve block is connected with a left reaction bed and a right reaction bed, a condenser valve block is connected with a left condenser and a right condenser, an evaporator valve block is connected with a left evaporator and a right evaporator, the left reaction bed, the left condenser and the left evaporator are connected in sequence, and the right reaction bed, the right condenser and the right evaporator are connected in sequence. According to the efficient moisture absorption-thermal chemical reaction single-stage thermode driven by low-grade heat energy, the circulating moisture absorption capacity is greatly improved, and thus the density of the energy flow is increased; meanwhile, the quality of low-temperature fluid is improved, and high-temperature fluid is obtained. When the temperature of a heat source is 95 DEG C and the condensing temperature is 15 DEG C, the temperature of the heat source can be increased to 125 DEG C from 70 DEG C, and the energy density of a system can reach 1.86kWh / kg; internal energy storage is achieved, moisture-absorption salt is separated from refrigerating fluid during energy storage, and no loss can be caused; when the temperature of the low-temperature fluid needs to rise, a user just needs to enable the moisture-absorption salt to be in contact with with the refrigerating fluid, and thus the high-temperature fluid can be obtained.
