Abstract

The invention provides a chemical refrigerant for a coal mine emergency hedge system, which aims at solving the technical problems that the refrigeration of carbon dioxide and the refrigeration of an ice storage air conditioner are not perfect, the refrigeration of carbon dioxide has high cost, a large space is occupied and hidden danger of explosion is caused. The cooling capacity of the power supply required for ice storage refrigeration is uncontrollable. The chemical refrigerant is formed by sufficiently mixing 30-50% of ammonium chloride, 5-15% of potassium chloride, 40-60% of urea and trace pigment and essence. The chemical refrigerant provided by the invention is used as a refrigeration system of a coal mine emergency hedge system.

Description

technical field [0001] The invention relates to a chemical refrigerant used in a coal mine emergency avoidance system for providing cooling capacity for an environment space. Background technique [0002] At present, the refrigeration systems used in coal mine emergency avoidance systems are mainly carbon dioxide refrigeration and ice-storage air-conditioning refrigeration. These two refrigeration methods are not perfect. For example, carbon dioxide refrigeration is expensive, takes up a lot of space, has potential explosion hazards, and is prone to leakage Condition. Ice storage refrigeration requires the power to be turned on all the time, which consumes a lot of energy and the cooling capacity is uncontrollable. They are not suitable for application in coal mine emergency avoidance systems. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a chemical refrigerant used in a coal mine emergency avo...
