Embedded air conditioners are not vertical or hanging air conditioners. In the past, there was a type of window air conditioner, which was installed by making a hole the size of an air conditioner in the wall and placing it inside. This type of air conditioner combines a condenser and an evaporator (nowadays, air conditioners basically use a separate condenser and evaporator, with one unit indoors and one unit outdoors). This type of air conditioner has a relatively high power and good cooling effect. There is also a type of embedded air conditioner called a ceiling air conditioner.
