The present invention relates to an air conditioner, and more particularly, to an air conditioner in which a plurality of combined air inlets and outlets through which air is sucked or discharged are formed, and a plurality of blower fans are disposed in parallel.

In general, an air conditioner uses a refrigeration cycle of refrigerant consisting of a compressor, a four-way valve, an outdoor heat exchanger (condenser or evaporator), an expansion device, and an indoor heat exchanger (evaporator or condenser) to create a more comfortable indoor environment for the user. By cooling or heating, it is largely divided into a separate type and an integrated type.

The separation type and the integrated type are functionally the same, but the separation type has a cooling / heating device, an indoor fan and an indoor fan motor installed in the indoor unit, and a heat radiation / cooling device, a compression device, an outdoor fan and an outdoor fan motor installed in the outdoor unit. The indoor and outdoor units separated from each other are connected by a refrigerant pipe, and the integrated type integrates the function of cooling heat dissipation to drill holes in the walls of the houses or directly install the devices by hanging the windows.
