Military air conditioner superhigh-temperature refrigeration system

Abstract

The invention discloses a military air conditioner superhigh-temperature refrigeration system. The system comprises a compressor, a condenser, a reservoir, a thermal expansion valve, an evaporator, a gas-liquid separator and a temperature response expansion valve assembly, wherein the temperature response expansion valve assembly comprises a valve body and a temperature-sensitive bag which are connected through a capillary tube, an inlet pipe of the valve body is connected with a connecting pipeline between the reservoir and the thermal expansion valve, an outlet pipe of the valve body is connected with a connecting pipeline between the evaporator and the gas-liquid separator, and the temperature-sensitive bag is closely attached to an outlet pipe of the compressor. According to the invention, through arrangement of the temperature response expansion valve assembly, military air conditioner equipment can realize reliable refrigeration at an ambient temperature as high as 65 DEG C, and comfortableness of occupants in a vehicle and play of the fighting strength of a weapon system are guaranteed.

Description

technical field [0001] The invention relates to the field of military air conditioners, in particular to an ultra-high temperature refrigeration system for military air conditioners. Background technique [0002] Military or special vehicles are the main combat equipment of modern ground warfare. Due to the harsh weather conditions and driving conditions in the field, the environmental conditions in the vehicle deviate far from the physiological and hygienic standards of the human body, seriously affecting the working ability of the occupants. According to relevant data, the main factors affecting the microclimate in the car are temperature, humidity, air flow velocity and the average radiant temperature of the surrounding surfaces. As far as the occupants in the car are concerned, the main factor is temperature. For example, under severe weather conditions with high temperature, the attention will be deteriorated by 70%, the short-term memory of numbers and symbols will b...

AI Technical Summary

Problems solved by technology

[0005] 1. The ambient temperature can reach up to 55°C, which cannot meet the needs of armored vehicles at ultra-high ambient temperatures

[0006] 2. The closer the ambient temperature of the traditional high-temperature refrigeration system is to 55°C, the closer the compressor works to the limit state

[0007] To sum up, the traditional military air-conditioning high-temperature refrigeration device is no longer suitable for the current development trend of military air-conditioning technology
