Overview

Air supplied the ventilation system in the vehicle interior can be heated or cooled depending on the conditions of comfort, selectable by the driver and passengers. Heating and air-conditioning separate, but their units and components are located inside the vehicle in a common housing under the dashboard. The entire flow of air submitted to salon is sent for heating or cooling through the same casing. The temperature and air flow rate are controlled by the same controls.

The heat generated when the engine is transmitted to the radiator coolant heater, located in the cabin. The supplied air flow from the ventilation system passes through the cooler and heated by the heat of the engine coolant flowing in the radiator.

The air conditioning system removes excess interior heat and moisture. Refrigerant circulating a liquid in a part of the system where higher pressure is maintained, evaporated and gasified in the area of low pressure. When expanding gas cools accompanied by removal of heat from the air supplied by the fan into the passenger compartment, and lowering its temperature. Further, as it passes through the condenser, the refrigerant gives the absorbed heat to the surrounding air. The cycle of heat transfer continues indefinitely as refrigerant in a closed circuit. Of the air supplied to the room, the moisture is removed by condensation on the refrigerating compartment evaporator.
