Double-layer phase change cool storage air conditioning garment

Abstract

The invention relates to a double-layer phase change cool storage air conditioning garment. The double-layer phase change cool storage air conditioning garment includes a garment body and a cool storage material, the garment body is formed by an outer layer in a waistcoat shape, a storage layer of the cool storage material, a phase change film layer, and an inner layer in the same shape with the outer layer, wherein the outer layer, the storage layer, the phase change film layer and the inner layer are sewed together, the inner surface of the outer layer is in contact with the outer surface ofthe storage layer of the cool storage material, the inner surface of the storage layer of the cool storage material is in contact with the outer surface of the phase change film layer, the inner surface of the phase change film layer is in contact with the outer surface of the inner layer, the inner layer is in contact with a human body, and the cool storage material is placed in the storage layer of the cool storage material. The double-layer phase change cool storage air conditioning garment is simple in structure, discomfort of the human body in the open space in the hot environment is solved, the weight of the cool storage material is decreased, appearing of extreme discomfort of the human body skin surface is avoided when cool energy is released into the human body, and use time of the air conditioning garment is prolonged.

Description

technical field [0001] The invention relates to an air-conditioning garment, in particular to a double-layer phase change cold storage type air-conditioning garment. Background technique [0002] Outdoor workers such as traffic police and firefighters and personnel wearing closed protective clothing will inevitably work in high-temperature environments in open spaces. The high temperature environment will cause a series of physiological and psychological changes such as hypoxia, reduced anti-stress endurance, and distraction, which will seriously affect the psychological, emotional and physical health of personnel and reduce work efficiency. Therefore, the cooling needs of the human body in open spaces and high-temperature environments need to be urgently addressed. The traditional air conditioner cools the individual in the way of cooling the space. It is impossible to change the parameters of the surrounding environment of the human body by adjusting the air in an outdoor...

Problems solved by technology

However, since the phase transition temperature of ice is 0°C, when ice releases cold energy to the human body, on the one hand, it will cause extreme discomfort on the human skin surface, and on the other hand, it will cause rapid release of cold energy in the initial stage, which cannot ensure uniform release. Happening

Other phase change materials, such as organic phase change materials such as paraffin or alkane, although the phase change temperature is close to the surface temperature of human skin, the cold storage density is 100~200 kJ / kg, which is about 1 / 3~1 / 2 of ice. Cold storage density is low

This has resulted in that in order to ensure sufficient cold storage capacity, the weight of the phase change material carried by the human body needs to be increased by 2 to 3 times, and the excessive load will increase the heat production of the human body and increase the heat load of the human body
