Embodiment Construction

[0015] Examples, see figure 1 , Fig. 2 and Fig. 3, a cooling device 6 is installed on the upper casing of the fan motor 3. The cooling device 6 includes a cooling plate 6-1 and a cooling water pipe 6-2. The cooling plate 6-1 is made into an arc shape according to the shape of the upper shell of the motor 3, and is fixed with the fan motor 3. The cooling water pipe 6-2 is coiled and fixed on the Cooling plate 6-1 on the plate body. The inlet of the cooling water pipe 6-2 is connected to the outlet pipe 7 of the water receiving tray; the outlet of the cooling water pipe 6-2 is connected to the drain pipe 5.

[0016] The number of layers of the cooling plate 6-1 and the number of turns of the cooling water pipe 6-2 are determined according to design requirements. It can be multi-layer multi-turn, or single-layer multi-turn.

[0017] The condensed water discharged from the water receiving tray 8 → the water receiving tray outlet pipe 7 → the multi-circle cooling water pipe 6-2 ...

Abstract

The invention provides a cabinet-type air conditioner that uses condensed water to cool down the fan motor of the indoor unit. It includes an indoor unit, the indoor unit includes a fan motor, an evaporator and a water receiving tray at the lower part of the evaporator, and is characterized in that: A cooling device is arranged on the top, the water outlet pipe of the water receiving tray communicates with the cooling device, and the water outlet of the cooling device communicates with the condensed water drain pipe. Condensed water discharged from the water tray → outlet pipe of the water tray → multi-turn cooling water pipe → drain pipe → outdoor. During the above condensed water circulation process, the condensed water cools the cooling plate, and then cools the fan motor through the joint action of the cooling plate and the cooling water pipe. In this way, the heat dissipated by the fan motor can be restrained from blowing upward to the evaporator, eliminating the cooling capacity of the evaporator offset by the heat of the fan motor, and improving the cabinet EER.

Description

technical field [0001] The invention relates to a cabinet type air conditioner, in particular to structures such as a fan motor of an indoor unit of the cabinet type air conditioner. Background technique [0002] The fan motor of the cabinet indoor unit generally adopts an AC motor, and the efficiency of the AC motor is low. In the cooling condition, the fan motor will generate about 50-90w of heat when it is running, and it will be blown to the evaporator by the wind to offset part of the cooling capacity of the evaporator and reduce the cooling capacity. At the same time, the temperature of the condensed water generated by the indoor unit is about 8-12°C, but it is directly discharged, and the potential of the condensed water is not utilized, resulting in a low cooling EER of the cabinet unit and increased power consumption. [0003] How to suppress the convective flow of heat from the fan motor to the evaporator and maximize the use of the latent heat of the condensed wa...
