Dual-system integrated multi-substance phase-change heat transfer compressor condensing unit

Abstract

The invention discloses a dual-system integrated multi-substance phase-change heat transfer compressor condensing unit, and belongs to the technical field of refrigeration equipment. According to the dual-system integrated multi-substance phase-change heat transfer compressor condensing unit, condensation waste heat discharged by a refrigeration compressor unit is utilized, heat energy of the condensation waste heat is used for absorption refrigeration work, after the refrigeration compressor unit absorbs heat of matter phase-change heat transfer of a lithium bromide absorption refrigeration system, the supercooling degree of a liquid refrigerant of the refrigeration compressor unit can be reduced, the enthalpy difference value of the refrigerant can be increased, and meanwhile, the suction superheat degree of a circulating refrigerant is reduced, the specific volume of a gaseous refrigerant is reduced, the refrigerant circulation amount of the refrigeration system is increased, and meanwhile the refrigeration efficiency of the refrigeration compressor unit is improved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration equipment, and in particular relates to a compressor condensing unit with dual-system integration and multi-substance phase-change heat conversion. Background technique [0002] The refrigeration system is mainly composed of four major equipments: compressor, condenser, throttling element, and evaporator. These equipments are connected in sequence through pipelines and pipeline accessories to form a closed system. The refrigerant circulates continuously in the air conditioning system through the four processes of compression, condensation, throttling, and evaporation, and then achieves the purpose of refrigeration. [0003] In the refrigeration system, the task of refrigeration is to take out the heat in the cooled object and transfer it to the surrounding medium (water or air) with a higher temperature, so that the temperature of the object is lowered, and the heat cannot be spontaneously t...

AI Technical Summary

Problems solved by technology

[0003] In the refrigeration system, the task of refrigeration is to take out the heat in the cooled object and transfer it to the surrounding medium (water or air) with a higher temperature, so that the temperature of the object is lowered, and the heat cannot be spontaneously transferred from the cold object to the surrounding medium (water or air). For hot objects, if heat needs to be transferred from cold objects to hot objects, external work must be consumed. Therefore, the condensation waste heat discharged by the existing refrigeration system is wasted and not well utilized.
