Problems solved by technology

However, in the air conditioner disclosed in Japanese Patent Application Laid-Open No. 2-247434, during regular inspection and maintenance, the operator has to face the narrow space inside the cabinet installed on the ceiling in a posture of looking up, and perform difficult operations. Therefore, maintenance work (including coolant recovery and replacement work) takes a long time
[0007] In addition, even when a small problem occurs, it is difficult for the user to repair it, so more serious problems may be caused by not taking timely measures

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail based on the drawings showing preferred embodiments. Fig. 1 is a plan view of the air conditioner of the present invention, and Fig. 2 is a side view of the air conditioner of the present invention.

[0025] As shown in FIG. 1 , the air conditioner of the present invention has an exhaust air passage A and an air supply air passage B inside a rectangular box-shaped casing 1 . As shown in FIG. 2 , the casing 1 is fixedly supported on the ceiling surface R of the room where the air conditioner is installed. As shown in FIG. 1 , the exhaust air duct A and the air supply air duct B are formed by dividing the interior of the casing 1 into two parts through a partition plate 16 along the length direction, and are arranged parallel to each other.

[0026] The air supply duct B has an external air inlet 10 opened at one end in the extending direction and an air supply port 11 opened at the other end. The external a...

Abstract

The invention provides a ceiling-mount air conditioner arranged inside a shell of a heat pump unit which is arranged on an indoor ceiling. The air conditioner hangs a support stand through a retractable support component, and leads the heat pump unit to be arranged at the stand. When implementing maintenance work, the stand is pulled out of an opening below the shell through extending the support component; therefore, the operating personnel can approach easily to the heat pump unit on the stand, and implement operation in a comfortable posture.

Description

technical field [0001] The present invention relates to a ceiling-installed air conditioner in which a heat pump unit is installed inside a casing installed on the indoor ceiling. Background technique [0002] As an air conditioner that uses a heat pump to adjust indoor cooling and heating, there are currently a supply air heat exchanger that exchanges heat with the supply air supplied to the room, an exhaust heat exchanger that exchanges heat with exhaust exhaust discharged from the room, and a coolant An indoor air conditioner that is installed in a common cabinet installed indoors in combination with other equipment that constitutes a heat pump, such as a coolant line for circulation and a compressor that compresses the coolant. [0003] Compared with the general air conditioner in which the indoor unit and the outdoor unit are separated, this air conditioner does not need to connect the indoor and outdoor coolant pipes and electric wiring, and it is easy to install, and ...
