Description

Air conditioner

The present invention relates to an air conditioner.

Conventional compact air conditioners require noise devices such as noise chambers to be installed in the duct paths in order to prevent the noise generated in the blower device from being directly transmitted to the living room through the ducts with the air that is directly harmonized.

In addition, since the blower including the heavy motor is located in the upper part of the air supply chamber, and the center of gravity of the air conditioner is high, the stability of light operation during installation work and transportation is poor, and during maintenance, Difficulties in maintenance work.

In addition, the conventional heat exchanger arrangement has a structure in which the number of heat is large in order to make the main body of the apparatus compact and at the same time satisfying the required capability, thereby increasing the static pressure loss and increasing the power of the blower, resulting in increased noise. Will have
