THE STUDY OF THE ENGINE COOLING SYSTEM IN REGULATING THE AIR TEMPERATURE AT THE OUTLET OF THE HEATER OF AIR CONDITIONER SYSTEM OF THE TRUCK CABIN

The studies are aimed at assessing the possibility of regulating the air temperature at the exit from the air conditioning system of the truck cabin by shutting off the control valve with a different way of connecting it to the cooling system. As a result, a variant of connecting a control valve with a bypass channel with a diameter of 0,045 mm is proposed. In this case, the air temperature at the output of the heater of the air conditioner is adjustable in the range from 66,7 to 37о С at coolant flow rates of 0,067-0,029 kg / s.
