1. At present, the main form of warm air in automobiles is water heating. Its heat source comes from engine coolant. When the temperature of coolant is high, it flows through the heat exchanger in the heating system, and the blower exchanges heat between air and engine coolant. Finally, the heated air is sent into the car through various air outlets. Simply put, the heat of the engine coolant is not wasted, and the automobile heater transfers heat through the engine coolant, so it will not increase fuel consumption!
How can a car turn on warm air without air conditioning?
① Don't turn on the air conditioner after the car starts, and then turn on the warm air after the pointer of the engine water thermometer reaches the middle position.
② A/C is the abbreviation of air conditioner, which is the switch of air conditioner and refrigeration. There is no need to turn on the air conditioner when the warm air is turned on.
③ The warm air temperature should be controlled at 18℃~25℃. First of all, this is the most comfortable temperature for human body. Secondly, if the temperature is higher, the engine may need to do extra work, which will increase fuel consumption.
④ Adjust the cycle mode of air conditioner to in-vehicle cycle. If the air in the car is turbid and the oxygen content drops, it can be adjusted to external circulation.
⑤ Using the air conditioner for a long time will increase the burden on the condenser and cause losses to the refrigeration system. So, you can turn off the air conditioner in time, let it "have a rest" and turn it on later.
⑥ Turn off the air conditioner three to five minutes before turning off the engine, which can not only reduce the fuel consumption, but also avoid the air conditioner from generating odor. If you don't turn off the air conditioner, mold will grow in the air conditioner, and when you start it again, the vehicle will catch fire with the pressure of the air conditioner starting, causing damage to the engine.
