It can make some places obtain air with a certain temperature, humidity and air quality to meet the requirements of users and production processes and improve labor hygiene and indoor climate conditions. For the existing air conditioners with evaporative refrigeration mechanism, their cooling effect is relatively high. Good, but the energy consumption is high, the energy efficiency ratio is low, and the refrigerant is generally a fluorine-containing compound, which has certain pollution to the environment. In winter, the heating effect is poor, and the electrothermal conversion rate is lower than 70%. Part of the electrical energy is converted into mechanical energy. The consumption is very high, it uses heat transfer to heat, and the hot air is dry and uneven, and the heating effect is poor, and many other shortcomings, defects and disadvantages

The prior art also involves composite graphene as auxiliary heat energy for air conditioners, such as publication number CN107940583A, a composite graphene infrared heating and cooling air conditioner indoor unit, which consists of a casing, an evaporator, a heat insulation layer, a fan, a carbon fiber heating tube, Composed of high temperature resistant composite graphene infrared coating heat sink; the card strip on the carbon fiber heating tube is connected with the card slot on the high temperature resistant composite graphene infrared coating heat sink in a buckle way; the high temperature resistant composite graphene infrared coating dissipates heat The sheet is a louver-shaped sheet structure sprayed with a high-temperature resistant composite graphene infrared coating on an aluminum alloy carrier and provided with a card slot; The heat sink is sprayed on the aluminum alloy carrier, so there is still no change in the use of tubular carbon fiber to generate heat unevenly, and the temperature in the heating zone of the carbon fiber tube is high. The heat conduction through the aluminum alloy main heat sink still needs to be blown out by the fan through the secondary heat transfer, and the thermal efficiency is relatively high. The problem of low efficiency is still not solved, and the problem of efficiency, we know that in order to make composite graphene produce thermal radiation function, it must be produced through conduction and molecular collision, and the existing patented technical solutions are simply impossible to make composite graphene coating conductive. Therefore, it is impossible to produce composite graphene thermal energy radiation. The above air conditioner technologies all have certain defects, which affect the application of composite graphene and the development of air conditioning energy-saving technology, which need to be solved urgently.
