Is the inlet pipe of Excelle heating pipe thick or thin?

Excelle heating water pipe inlet pipe is thick. The inlet pipe is hot and the outlet pipe is cold. The lack of antifreeze in the cooling system is the most common reason why the warm air is not hot. The hot water pipe of the car is thicker and warms faster.

Automobile air conditioning composition

Modern air conditioning system consists of refrigeration system, heating system, ventilation and air purification device and control system. Ventilation system, its function is to ensure the indoor ventilation when the car is driving, that is, fresh air is constantly rushing into the car room to drive and exhaust the dust, carbon dioxide and harmful gases of the engine. In the cold winter, the fresh air should also be heated to ensure the indoor temperature is suitable.

Heating system, its function is to heat the air in the car or the fresh air entering the car from the outside, so as to achieve the purpose of heating and dehumidification. Refrigeration system: its function is to reduce the temperature inside the car when the ambient temperature outside the car is high, so that passengers feel cool and comfortable. Air purification system, its function is to filter the introduced air, constantly eliminate the dirty gas in the car and keep the air in the car clean.

Control system, which is mainly composed of electrical components, vacuum pipes and control mechanisms. On the one hand, it is used to control the temperature and pressure of refrigeration and heating system, on the other hand, it is used to control the temperature, air volume and flow direction of indoor air to improve the function of air conditioning system.
