Vacuum atomization phase change refrigeration plant

Abstract

The invention discloses a vacuum atomization phase change refrigeration plant which comprises an atomizer, an atomization cavity, a self-adaption pressure control valve, a heat exchanger and a vacuumpump. The atomizer is used for atomizing refrigerating fluid and is installed in the atomization cavity, the self-adaption pressure control valve comprises a valve channel, a valve plate plugging theinterior of the valve channel and at least one pressure control valve body distributed on the valve plate, the inlet end of the valve channel communicates with the atomization cavity, the outlet end of the valve channel communicates with a cold source inlet of the heat exchanger, different opening degrees of the pressure control valve bodies can be formed according to different pressure differences of the two sides of the valve plate, air mist can enter the cold source inlet of the heat exchanger through the pressure control valve bodies, and an air sucking opening of the vacuum pump communicates with a cold source outlet of the heat exchanger. By means of the vacuum atomization phase change refrigeration plant, the refrigerating efficiency is improved, the running cost is reduced, energyconservation and environmental protection are achieved, and no special requirement for the refrigerating fluid is needed.

Description

technical field [0001] The invention relates to the technical field of industrial refrigeration, in particular to a vacuum atomization phase-change refrigeration equipment. Background technique [0002] There are several ways to cool the heat source process medium in most existing industrial applications: [0003] 1. Through the heat exchanger, the cooling water is used to cool the heat source medium. Most of the industrial cold sources are circulating cooling water. After the heat exchange between the cooling water and the heat source, the temperature rises, and then evaporates and dissipates heat through the cooling tower to regain normal temperature water. The cooling tower uses unsaturated air to fully contact with hot water for evaporative cooling. The total water volume of the entire circulating water is constantly lost, so fresh water needs to be replenished all the time. This cooling process has simple equipment and no additional pollution. The cooling water obtaine...

AI Technical Summary

Problems solved by technology

Although this cooling process can obtain lower temperature refrigerant, the equipment is complicated, and the refrigerant is relatively expensive. Once there is leakage, it will cause environmental pollution, and all refrigerant pipes need to be heat-insulated, but it will still be There is a large heat loss (the insulation layer pipe absorbs heat, causing the temperature loss of the refrigerant)

Especially for centralized refrigeration equipment, the heat loss of refrigerant is even more difficult to avoid and eliminate

The refrigeration compressor system needs to be equipped with a compressor and a circulating water pump, a system consisting of a complete set of industrial sensors, and the energy consumption is very high
