Abstract

The invention discloses a compression-injection composite refrigeration system utilizing a Knudsen compressor, which consists of a waste (waste) heat exchanger, a first ejector, a second ejector, a condenser, a first regenerator, a first Throttle valve, evaporative condenser, first Knudsen compressor, second Knudsen compressor, second regenerator, evaporator and second throttle valve; the system is divided into two parts: compression refrigeration and injection refrigeration, Connection through common evaporative condenser and evaporator. The ejector is driven by residual (waste) heat, and the two Knudsen compressors can be driven by residual (waste) heat or solar energy. The whole system is excellent in energy saving and environmental protection, and there are no moving parts, and no lubrication is required. The settings of the two regenerators respectively increase the superheat of the refrigerant entering the Knudsen compressor to prevent the liquefaction of the refrigerant inside the Knudsen compressor; the subcooled refrigerant of compression refrigeration and injection refrigeration are combined and flow into the evaporator, Improve the efficiency of the whole system.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a refrigeration system utilizing Knudsen compression and jet compounding, which is driven by residual (waste) heat and solar energy. Background technique [0002] In 1990, the mechanical compression-jet refrigeration cycle and the pressurized jet refrigeration cycle were proposed by Kornhauser and Sokolov respectively. Since then, these two refrigeration cycle theories have been extensively studied and further improved. The mechanical compression-jet refrigeration cycle initially used the ejector to recover the expansion work in the mechanical compression refrigeration cycle to reduce the power consumption of the mechanical compressor; later, the ejector was used to recover the heat of the superheated refrigerant at the outlet of the mechanical compressor to reduce condensation resulting heat loss. The supercharged injection refrigeration cycle uses a mechanical compressor to increa...
