It includes: relational expression, the relational expression of clothing thermal resistance and outdoor temperature of passenger capacity and mean radiant temperature and metabolic rate；
The air-conditioning equipment is also used to control the frequency and/or frequency of compressor of air conditioner in air-conditioning system according to temperature control curve
Rate change rate, and temperature is adjusted according to the frequency of compressor of air conditioner and/or frequency change rate control air-conditioning system；Wherein, vehicle
Network exports passenger capacity, outside temperature, vehicle interior temperature signal to fuzzy Control frequency of air condition compressor or its change rate.
