[0002] The difference between air conditioners and ordinary fans is that they can provide cooling or heating to users.

[0003] Wind or warm air, however, according to the principle of equal energy exchange, the air conditioner will inevitably generate heat when cooling, and will inevitably produce relative cooling when heating.
