一、现状机械保温车制冷和调温的过程主要由两个系统进行工作。一个是制冷加温系统,由制冷机、换热器、电热器等组成。其功能是制造出车内需要的冷量或热量。另一个是通风系统,由通风机、风道、送风口及回风口等组成,其功能是把制冷加温系统制造的冷量或热量传送到车内,以冷却或加热车内的 First, the status quo Mechanical insulation car cooling and thermostat process mainly by the two systems work. One is a refrigeration heating system, from the refrigerator, heat exchanger, electric heater and other components. Its function is to create a need for cold or heat inside the car. The other is the ventilation system, by the fan, duct, outlet and return air outlet and other components, its function is to cool the heating system manufacturing cooling or heat transfer to the car to cool or heat inside the car
