Abstract

The present invention proposes a novel absorption-jet compound refrigeration system. The technical problem to be solved is that the existing absorption refrigeration system cannot make full use of low-grade waste heat and solar energy, and its efficiency is low. The present invention includes an absorption circulation subsystem, an injection circulation subsystem and a pressure regulation subsystem. The generator vent port is connected to the condenser through a high-pressure ejector, the condenser is connected to the evaporator, and the evaporator is connected to the absorber through a low-pressure ejector. The outlet of the absorber is connected to the solution inlet of the generator through a solution heat exchanger; the outlet of the vaporizer is divided into two paths, one path is connected to the power nozzle of the high-pressure injector, and the other path is connected to the power nozzle of the low-pressure ejector. The present invention after adopting the above technical solution solves the problem that the traditional absorption refrigeration system cannot work normally due to insufficient deflation of the generator under the conditions of low heat source temperature, low evaporation temperature and high cooling water temperature.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a novel absorption-jet composite refrigeration system. Background technique [0002] At present, a large amount of low-grade thermal energy has not been fully utilized by people. This heat energy mainly includes waste heat generated in industrial production and living processes, as well as ground energy and solar energy. As far as waste heat is concerned, according to the statistics of the International Energy Agency (IEA), 50-60% of the current global annual total energy consumption is lost in the form of waste heat. Waste heat has a wide temperature range, but for low-temperature waste heat, there are currently few ways to recycle it. [0003] Building energy consumption accounts for a considerable part of the total energy consumption of society, and 40% of building energy consumption is air conditioning energy consumption. At present, waste heat and solar refrigeration systems are ...
