Also, cover a plurality of pipe connection ports with a plurality of heat insulating molding materials,
Furthermore, by covering it with a pipe cover, it is possible to solve the problem of aesthetic appearance due to aging and the problem of damage to the pipe connection part due to external factors, but the addition of new parts increases the material cost and installation work In addition, the number of construction man-hours has increased, and furthermore, the pipe connection port and its cover project from the outer surface of the outdoor unit main body, so the effective use of the installation space is not fundamentally possible and the exterior is lacking. There is.

Therefore, the present invention treats the dew condensation water from the pipe connection port without adding new parts, prevents damage to the pipe connection portion due to external factors, and prevents the initial and after aged deterioration. It aims to improve the aesthetics and to make effective use of the installation space.
