Although the idea of No. 99853 has been proposed, it has not been implemented in which rotary heat exchangers are arranged in two stages, upper and lower, in a plane perpendicular to the airflow. In the case where the heat exchanger is arranged in stages, the heat exchanger is fixedly arranged.

力即ち冷却能力を著しく低下させる欠点がある。Problems to be solved by the invention In the above-mentioned structure in which the fixed heat exchangers are arranged in two stages, upper and lower, the drain generated in the upper heat exchanger is drained into the lower drain pan by providing a dedicated drain receiver. However, if rotary heat exchangers are arranged in two stages, upper and lower, providing a drain receptacle exclusively for the upper rotary heat exchanger may be a problem due to space issues within the air conditioner casing. This method is difficult to adopt due to problems such as air resistance, and if the condensate generated in the upper rotary heat exchanger is allowed to fall directly onto the fin surface of the lower rotary heat exchanger, the condensate will be removed by the air flow. This has the disadvantage that it scatters to the downstream side and forms a water film on the fin surface of the lower stage rotary heat exchanger, significantly reducing the heat exchange capacity, that is, the cooling capacity.

By discharging the water through the attached dedicated drainage channel, the purpose is to prevent the drain from scattering to the downstream side and reduce the heat exchange capacity, that is, the cooling capacity, of the lower rotary heat exchanger. It was devised.

たものである。Means for Solving the Problems As stated in the claims of the utility model registration, the present invention provides for an upper heat exchanger and a lower heat exchanger to be connected in a plane orthogonal to the air flow within the casing of an air conditioner. The heat exchangers are arranged in two stages, upper and lower, and can rotate between two positions: a position perpendicular to the air flow and a position parallel to the air flow, and both heat exchangers occupy positions perpendicular to the air flow. The clearance between the bottom of the upper heat exchanger and the top of the lower heat exchanger for rotation is as follows:
It is closed by a partition plate attached to the air flow downstream side of the top surface portion, and a box-shaped frame pan having four peripheral walls and opening upward is on the top surface of the lower heat exchanger. A drain hole in a frame pan for receiving drain on the bottom of the upper heat exchanger is opened toward the frame pan on the top of the lower heat exchanger. The drain outflow hole opened in the frame pan is connected to the drain receiving frame pan at the bottom of the lower heat exchanger through a dedicated drainage channel. This solves the problem of drain processing when heat exchangers are arranged in two stages, upper and lower.

力即ち冷却能力を低下させることも無い。Effect According to the configuration of the present invention, during cooling, condensate generated by condensation on the rotary upper heat exchanger is transmitted through the fins and onto the frame pan that covers the entire top surface of the rotary lower heat exchanger. After flowing down to the drain, it flows into a dedicated drainage channel from the drain outlet hole and is discharged, and since it does not flow through the fins of the lower heat exchanger, it prevents the drain from scattering to the downstream side of the air flow and preventing the drain from flowing into the lower heat exchanger. There is no reduction in heat exchange capacity, that is, cooling capacity.

The water flows into the drainage channel 14 from the drain outlet hole 13 without flowing into the water, and is discharged to a drain pan (not shown) arranged below the lower heat exchanger 2.

The condensate that has flowed down onto the frame pan 10 of the lower heat exchanger 2 will not flow down through the fins 18, and the fins 18 will have water droplets from the condensation caused by the action of the lower heat exchanger 2. Therefore, the heat exchange ability, that is, the cooling ability, is not inhibited, and the phenomenon in which a large amount of drain flowing down by the air flow A is scattered to the leeward side does not occur.
