Air conditioner outdoor unit used for improving efficiency of condenser by utilizing condensate water atomization and cooling

Abstract

The invention relates to an air conditioner outdoor unit used for improving the efficiency of a condenser by utilizing condensate water atomization and cooling. The air conditioner outdoor unit comprises a fan center disc and an atomizing device. According to the air conditioner outdoor unit, the positions of the condenser and a fan are rearranged, the condenser is arranged close to an air outletside plate, the fan is arranged close to an air inlet side plate, one end of the fan is connected with an output shaft of a motor, and the other end of the fan is connected with the atomizing device through the fan center disc; the motor is arranged close to the air inlet side plate, and the atomizing device comprises a center disc connecting section and a condensate water atomizing section, wherein the center disc connecting section is in a hollow cylinder shape and is connected with the fan center disc; the condensate water atomizing section is in an arc-shaped cone shape, an atomizing device water inlet is formed in the side, far away from the fan, of the condensate water atomizing section, and the side wall of the condensate water atomizing section is provided with a plurality of atomizing holes parallel to the output shaft of the motor; and one end of a condensate water diversion pipe is inserted into the atomizing device water inlet. According to the outdoor unit, condensate water is reasonably utilized by virtue of centrifugal atomization, so that the heat dissipation efficiency of the condenser is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner outdoor unit which utilizes condensed water atomization to cool down and improve the efficiency of a condenser. Background technique [0002] Household air conditioners will discharge a certain amount of condensed water when they work in summer, especially in areas with relatively humid climates, the amount of condensed water generated will be greater. The temperature of the condensed water is about 10-15°C, and the water quality is relatively pure. General air conditioners discharge the condensed water directly to the drainage pipe or outdoors, which causes a waste of resources, is not conducive to the rational utilization of energy, and brings a lot of inconvenience to people's lives and the environment. [0003] People have proposed some methods of using condensed water. Among them, the Chinese patent application number 201710634810.6 d...

Problems solved by technology

The general air conditioner discharges the condensed water directly to the drainage pipe or outside, which causes a waste of resources, is not conducive to the rational use of energy, and brings a lot of inconvenience to people's life and the environment.

[0003] People have proposed some methods of using condensed water. Among them, the Chinese patent application number 201710634810.6 discloses a condenser cooling wind evaporation, humidification, cooling and efficiency air conditioner. The air conditioner absorbs condensed water through the sponge layer to cool the air. Sensible heat cooling of condensed water, limited reuse rate of condensed water cooling capacity

At the same time, the condensed water circulation system and the external water replenishment system of the device both need to be driven by a water pump, which increases the consumption of additional energy. Therefore, whether the device is energy-saving is open to question

The Chinese patent No. ZL200520067140.7 discloses a non-drip household air-conditioning energy-saving device, which directs condensed water to the fin surface of the condenser to form a liquid film to achieve the purpose of enhancing heat transfer, but the heat transfer theory shows that This kind of low-speed liquid film only adds a layer of heat transfer resistance, and the effect of actually enhancing heat transfer is very limited or even has a negative impact; at the same time, the device must use a water pump to realize the reuse of condensed water, so additional energy consumption is required. Therefore, the overall energy-saving effect of the device is poor, and the cost is also high
