Solar energy driven wearable minisize refrigeration and air conditioning system

Abstract

The invention provides a solar energy driven wearable minisize refrigeration and air conditioning system. The system comprises a wearable solar energy heat-collecting plate, a heat exchanger, a condenser and an evaporator, wherein the heat exchanger is connected with the output end of the solar energy heat-collecting plate and forms a heat exchange loop; the condenser is in parallel connection with the heat exchanger; the evaporator is in parallel connection with the condenser; an ejector is in series connection with a pipeline through which the condenser and heat exchanger are connected; a throttle valve is in series connection with the pipeline through which the evaporator and the condenser are connected; the loop is formed among the heat exchanger, the ejector and the condenser; the loop is formed among the ejector, the evaporator, the throttle valve and the condenser; the solar energy heat-collecting plate is worn at the chest or the back of a human body by straps; a minisize pump provided with a minisize power supply is connected to the pipeline of the evaporator; the evaporator is sewed in a front opening, a back opening, sleeves or trouser legs of clothing of a human body; and a refrigeration working medium flows in the system. In the solar energy driven wearable minisize refrigeration and air conditioning system, the solar energy injection type refrigeration and air conditioning system is introduced into the field of clothing for the first time; and the system has the advantages of simple structure, energy conservation and environment protection, can realize active refrigeration of a whole human body or a local body surface, and fulfills the aims of heatstroke prevention and cooling.

Description

technical field [0001] The invention belongs to the field of functional clothing, in particular to a miniaturized solar-driven wearable miniature refrigeration and air-conditioning system. The wearable miniature refrigeration and air-conditioning system can directly provide cold energy for the human body, and has the advantages of simple structure, stable operation, low noise, effective use of solar energy, and environmental protection and practicality. Background technique [0002] In the fields of energy, power, military, aviation, etc., high temperature is an unavoidable environmental factor for many man-machine systems. It will cause human hypoxia and reduced resistance to stress, distraction, memory loss, and reduced response flexibility. A series of physical and psychological changes. These all have a strong impact on the work mood and physical health of the staff, and will also have a great impact on the work quality and efficiency. In addition, prevention of heat s...
