Refrigerating system using swirling flow ejector

Abstract

A refrigerator with turbulence injector comprises a compressor, a condenser, an evaporator, and a turbulence injector, wherein the compressor outlet is connected with the inlet of the condenser whose outlet is connected with the nozzle of the turbulence injector, the high-temperature outlet of turbulence tube of the injector is connected with the inlet of the compressor, while the low-temperature outlet is connected with the inlet of the evaporator whose outlet is connected with the fluid inlet of the injector. The invention can recycle expansion energy of coolant, to improve 20% of energy / effect ratio, with simple structure and low cost.

Description

technical field [0001] The invention relates to a refrigeration system, in particular to a refrigeration system using a vortex ejector, and belongs to the technical field of refrigeration and air conditioning. Background technique [0002] Various refrigeration devices are widely used, and the importance of energy saving is becoming increasingly prominent. The use of ejectors is a way to improve the energy efficiency ratio of refrigeration cycles. An ejector is a device that replaces an expansion valve in a refrigeration cycle. The ejector of the prior art is a mature commercial product, and specific structural parameters can be referred to "Ejector", China Science Press, 1977; Due to the loss of throttling, it becomes heat energy, and this part of the expansion work cannot be recovered, resulting in a waste of energy. The ejector can be regarded as a device for recovering the expansion work of the refrigerant. Since the recovered expansion work is used to increase the re...

AI Technical Summary

Problems solved by technology

With a refrigeration system using only ejectors, the expansion work at the outlet of the ejectors has not been fully recovered, and the single vortex tube refrigeration is difficult to apply on a large scale
