Abstract

The invention discloses a refrigeration system and method based on secondary condensation boost absorption and subcooling compression; the heat collector is connected with the first hot water pump and the heat storage tank in sequence; connected; the generator is connected in sequence with the absorption cycle condenser, absorption cycle throttle valve, absorption cycle evaporator, secondary condenser, booster pump, absorber, solution pump, solution heat exchanger, and solution throttle valve; the main stage The circulation compressor is connected to the condenser, subcooler, primary throttling valve, and primary evaporator in sequence; the secondary circulation compressor is connected to the condenser, subcooler, secondary throttle valve, and secondary evaporator in sequence; The cold storage tank is connected with the absorption cycle refrigerated water pump and the absorption cycle evaporator in sequence; the cold storage tank is connected with the subcooling pump and the subcooler in sequence. This system uses the combination of secondary condensation and booster pump to replace the large water vapor compressor to achieve boost absorption, which broadens the range of heat source working conditions and significantly improves the performance of the system in low temperature heat source working conditions.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a refrigeration system and method based on secondary condensation, pressurization, absorption and subcooling compression. Background technique [0002] At present, the total energy consumption is showing a rapid upward trend. Therefore, realizing the transition from the fossil energy system to a low-carbon energy system is the direction of global energy transformation. [0003] Due to the advantages of solar energy, such as huge resources, convenient installation of photovoltaic power generation equipment, low transmission and distribution loss and high reliability, distributed photovoltaic systems have attracted much attention. [0004] Although the distributed photovoltaic system has excellent development potential, due to the high cost of power generation, there are certain restrictions on popularization. Therefore, improving the energy utilization efficiency of the distributed phot...
