Problems solved by technology

The traditional air-conditioning heating system is greatly affected by the engine water temperature (commonly known as the coolant temperature), and the heating effect of the system is poor when the engine water temperature is low
When the ambient temperature is low, the water temperature of the engine rises slowly, and sometimes it even runs for a long time in a state of low water temperature, resulting in slow response of the air conditioning heating system
