Now weather is slowly turning into winter, and temperature is dropping. I believe that few drivers will not turn on air conditioner. Many people will worry about whether turning on the air conditioner will increase fuel consumption.
In fact, hot air of air conditioner in winter does not increase fuel consumption much, but cold air of air conditioner in summer increases fuel consumption. In fact, we need to understand how car air conditioners work in order to understand what will lead to an increase in fuel consumption.
The energy of car air conditioner is provided by battery and motor. If you rely on an engine battery for power, it won't last long. To convert energy, engine must burn gasoline.
Shut up and turn on air conditioner to sleep and consume fuel. The engine must be running when car is on. If engine is not running for a long time, it will generate carbon deposits and draw more power from engine. engine, thereby increasing fuel consumption. When you turn on car with air conditioner on, engine always idles. In general, fuel consumption of a car with air conditioner on at idle is about 1-2 liters per hour. The fuel consumption of cars with different displacements at idle and with air conditioner on, it is also different. The larger displacement of car, higher fuel consumption.
It is not safe to sleep with air conditioner on at idle, and there is a risk of poisoning. The air in car cannot be convectored. Once carbon monoxide emitted by engine seeps into vehicle, it will gradually build up and increase in concentration, resulting in poisoning.
Reason for too high fuel consumption when air conditioner is on:
1. Too little refrigerant. If there is not enough refrigerant in air conditioning system, absorbed heat will also decrease, which will not only reduce cooling capacity, but also increase fuel consumption.
2. If temperature is always set very low, engine will run all time, which will draw more power from car's engine and put more stress on engine, which will naturally increase fuel consumption. engine.
3. Failure to regularly clean air conditioner air outlet and replace air conditioner filter will also increase fuel consumption when air conditioner is turned on.
4. Air in system is also one of causes of insufficient cooling. When air enters air conditioning system, pressure in cooling pipe will be too high, and poor refrigerant circulation will also lead to insufficient cooling.
