What are the modes of air conditioning?

I know this. There are three commonly used air conditioning modes. 1. refrigeration mode

refrigeration mode belongs to a common basic mode of air conditioning, and the refrigeration mode of air conditioning is mainly designed for lowering the indoor temperature during high temperature in summer. 2. heating mode

the heating mode of air conditioners is generally used in autumn or winter when the weather is cold, mainly to maintain the indoor temperature and make the overall temperature reach the range of human comfort. 3. Sleep mode

Sleep mode of air conditioner is often used when people rest and sleep at night. Under this air conditioning mode, not only can the loss of air conditioner be reduced, but also electricity can be saved, creating a more comfortable sleeping environment for sleeping people. Generally, when the air conditioner is set to sleep mode, the air conditioner will reduce the difference between the ambient temperature and the set temperature, thus reducing the operating pressure of the compressor and achieving the effect of saving electricity.
