Automotive air conditioner utilizing phase-change material for energy storage

Abstract

The invention provides an automotive air conditioner utilizing a phase-change material for energy storage. The automotive air conditioner is in communication with an intelligent terminal of an automobile owner, receives running instructions and runs according to the running instructions. The automotive air conditioner is characterized by comprising an energy storage part, an environmental heat exchange part and a power supply control part; the energy storage part adopts the phase-change material for storing cold or heat carried in a compressed refrigerating fluid; the environmental heat exchange part is used for utilizing the stored cold or heat to carry out heat exchange with the environment in an automobile; the power supply control part is linked with the energy storage part, the environmental heat exchange part and the intelligent terminal separately and consists of a solar panel and a control panel, the solar panel supplies power to the automotive air conditioner, and the controlpanel controls the energy storage part and the environmental heat exchange part according to the running instructions, wherein the phase-change material is used for storing the cold or heat carried inthe refrigerating fluid, the filling rate of the phase-change material is 90%, and the phase-change material is Mn(NO3)2 6H2O.

Description

technical field [0001] The invention relates to an automobile air conditioner, in particular to an automobile air conditioner utilizing a phase change material for energy storage. Background technique [0002] When parking in summer, due to the exposure of the car body, the temperature inside the car can often reach 60 ℃ ~ 70 ℃, which can seriously cause the car to spontaneously ignite. Such a high temperature inside the car will take tens of minutes even if the door is opened before getting on the car to dissipate heat. Traditional car air conditioners It is also necessary to reduce the temperature in the car to the comfortable temperature of the human body after the vehicle has been running for a period of time. Similarly, before getting on the car in winter, it is also necessary to preheat the vehicle for a period of time. After the temperature of the water tank rises, the air outlet of the air conditioner can blow out warm air. As above, in winter and summer, it takes a...

However, thermoelectric cooling has major limitations

First of all, the cooling efficiency of thermoelectric refrigeration is not high, only 1 / 4 of that of vapor compression refrigeration

Secondly, thermoelectric refrigeration has a large amount of heat dissipation at the hot end, so good heat dissipation conditions need to be provided, otherwise it is easy to burn out. In summer, the outdoor temperature is generally high, and it is easy to be exposed to the sun, so it is difficult to provide a good heat dissipation environment.

Again, the temperature difference between the hot and cold ends of the thermoelectric cooler is basically constant under a certain current (voltage), that is to say, when the outdoor temperature is too high, it is difficult for the thermoelectric cooler to reduce the temperature inside the car to the comfortable temperature of the human body.
