Description

technical field [0001] The invention relates to the technical field of refrigeration heat pumps, in particular to a compression-driven dual-temperature supergravity refrigeration heat pump system and method. Background technique [0002] In air-conditioning refrigeration / heat pump systems, dual-temperature heat sources are often involved, that is, the refrigeration system is required to provide two evaporation temperatures. In order to achieve this goal, the easiest way is to expand and depressurize the refrigerant to two evaporation pressures respectively, so as to obtain two evaporation temperatures, and then let the two refrigerant vapors at different evaporation pressures mix, and then pass through a The disadvantage of this method is that there is a mixing loss when the higher-pressure refrigerant vapor and the lower-pressure refrigerant vapor are mixed; in order to recover the energy of the higher-pressure refrigerant vapor, an improved method is The higher-pressure r...

[0003] However, the kinetic energy loss of the mixing process in the steam ejector still exists. In order to avoid this mixing loss, the patent application with the application number (CN201511026099.3) provides a high-gravity heat-driven refrigeration device, which uses high-gravity rotation to Inertial potential energy and pressure energy are converted to each other, without the throttling loss of the expansion valve and the mixing loss of different pressure refrigerant vapors, which has a good potential for energy saving, but this patent is driven by heat and can only provide one evaporation temperature, which cannot satisfy Use an electric compressor to drive to meet the needs of dual-temperature cold sources
