Expansion refrigeration portable air cooling air conditioning clothes

Abstract

The invention relates to expansion refrigeration portable air cooling air conditioning clothes which comprise an electronic control system, a refrigeration system and an air conditioning clothes body. The electronic control system comprises a DC power supply, a power supply controller and a high-speed motor. The refrigeration system comprises a turbo compressor, a turbo expander, a cooler and an axial fan. The DC power supply is connected with the high-speed motor and the axial fan through the power supply controller. The high-speed motor is connected with the turbo compressor and the turbo expander. The cooler is connected between the turbo compressor and the turbo expander. A PU pipeline is distributed in the air conditioning clothes body and connected with the turbo expander. Due to the fact that the required refrigeration amount is quite small, the turbo compressor and the turbo expander can be quite small; no liquid exists in the whole air refrigeration system, so safety and reliability are achieved; the clothes can be used at high environment temperature and in occasions with large vibration; the clothes are high in reliability, light in weight and long in service life and can solve the problems about safety, health and comfort of people in a high-temperature environment.

Description

technical field [0001] The invention relates to an air-conditioning garment, in particular to a portable air-cooled air-conditioning garment for expansion refrigeration. Background technique [0002] In steelmaking, construction, military police and other industries, due to the high temperature environment caused by equipment or weather, it is easy to make people who work at high temperature for a long time feel uncomfortable, reduce work efficiency, and even endanger their health. It is of great significance to improve the working environment of the staff and protect their health and life safety. [0003] At present, there are mainly the following types of air-conditioning clothing: one is that the air-conditioning clothing needs to be connected with a long conduit and an air compressor on the ground, and the air compressor provides compressed air for a period of time, and its disadvantage is that the activities of workers are restricted; The disadvantage is that the cooli...

[0003] At present, there are mainly the following types of air-conditioning clothing: one is that the air-conditioning clothing needs to be connected with a long conduit and an air compressor on the ground, and the air compressor provides compressed air for a period of time, and its disadvantage is that the activities of workers are restricted; The disadvantage is that the cooling effect of the miniature fan is poor and the expected effect cannot be achieved; one is to use the phase change of phase change materials such as dry ice and ice to absorb heat. Changing frequently is a hassle

[0004] Chinese patent, notification number CN203952509 provides a portable air-conditioning clothing, which utilizes the cooling effect of eddy current tubes. Due to the low efficiency of eddy current cooling, this method is not energy-saving and environmentally friendly, and cannot solve the problem of high-pressure air sources. The patent is provided with air ducts on the clothing body. There are multiple air outlet holes on the air duct, and the air duct is bent and arranged horizontally for many times, but it does not take into account the low specific heat capacity of the air during use, the cooling effect is difficult to cover the entire garment, and the cold air from the air outlet directly contacts the human body. Sweat is easily taken away, making the staff dehydrated
