Abstract

The invention discloses a refrigerating system and method based on secondary condensation pressurization absorption and supercooling compression. A heat collector is sequentially connected with a first hot water pump and a heat storage tank; the heat storage tank is sequentially connected with a second hot water pump and a generator; the generator is sequentially connected with an absorption circulating condenser, an absorption circulating throttle valve, an absorption circulating evaporator, a secondary condenser, a booster pump, an absorber, a solution pump, a solution heat exchanger and a solution throttle valve; a main-stage circulating compressor is sequentially connected with a condenser, a subcooler, a main-stage throttle valve and a main-stage evaporator; a secondary circulating compressor is sequentially connected with the condenser, the subcooler, a secondary throttle valve and a secondary evaporator; a cold storage tank is sequentially connected with an absorption circulating chilled water pump and an absorption circulating evaporator; and the cold storage tank is sequentially connected with a supercooling pump and the subcooler. According to the system, secondary condensation and the booster pump are combined to replace a large water vapor compressor to achieve pressurization absorption, and therefore, a heat source working condition range is widened, and the low-temperature heat source working condition performance of the system is remarkably improved.

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...
