Why doesn't Magotan air conditioner blow hot air?

The reasons why Magotan air conditioner does not blow hot air are: 1, the valve of warm air pipe and warm water tank are blocked; 2. Thermostats are usually opened or opened too early, leading to a large cycle of the cooling system prematurely. When the outside temperature is low, the cold air cools the antifreeze, and the engine water temperature will not come up; 3. The water pump impeller is damaged or lost, resulting in insufficient flow through the warm air small water tank; 4. There is air resistance in the engine cooling system, which leads to poor circulation of the cooling system, resulting in high water temperature and not hot warm air. Automobile air conditioning can adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, provide passengers with a comfortable riding environment and reduce travel fatigue. Automobile air conditioning generally includes refrigeration device, heating device and ventilation device.
