Comfort Calculation Model The air temperature, humidity, and wind speed on the body surface of an automobile air-conditioned room all have an impact on the comfort of the human body. As an evaluation criterion of the human body comfort level, it should be a comprehensive parameter. Authoritative departments at home and abroad have already done experimental research on this, and provided a graph of the relationship between human comfort and ambient temperature, humidity, and wind speed. In order to finally use the comfort index to evaluate the performance of the air conditioning system, it is necessary to determine the relationship between the comfort and the environmental parameters in a computational model. Regardless of the impact of the performance of automotive air conditioning and refrigeration systems, the outdoor environmental conditions and the vehicle operating speed are constant. Under the condition of constant indoor vehicle thermal load, the vehicle interior and exterior flow field and temperature field calculation model can achieve the following functions: The structural parameters of the vehicle in the structural model database are calculated. The distribution and temperature difference of the air distribution within the unmanned area, and the change rule of the air temperature field and flow field in the vehicle when the return air outlet position parameters, the shape of the air supply outlet, the size, and the cabin are changed. The rational distribution of the flow field and temperature field in the vehicle is the ultimate goal of the operation of the automotive air-conditioning system. Different models have different flow fields, temperature field distribution, and thermal loads. Therefore, different air conditioning and refrigeration systems need to be selected, and the actual operation of the air-conditioning and refrigeration system The performance also directly influences the distribution of the indoor flow field and temperature field by the actual air supply volume, air supply temperature, and other parameters. Therefore, the two are closely linked and affect each other. The evaporator air supply parameter and the indoor air return parameter are The two sets of data are the data between the air conditioning system and the car room. In the air-conditioning system design stage, there is no problem of two-way communication between the two sets of data, as long as the two parameters of the evaporator air supply parameters and the indoor air return parameters satisfying the thermal comfort of the vehicle interior are sent to the air-conditioning system design. The software can then design the air conditioning system. When the performance verification of the air conditioning system can meet the requirements of comfort air supply, there are two-way communication problems between the two parameters of the evaporator air supply parameter and the indoor air return parameter.
