Room air conditioner based on moisture storage heat exchanger and evaporative pretreatment

Abstract

The invention provides a room air conditioner based on a moisture storage heat exchanger and evaporation pretreatment, including an air conditioner unit, a water mist pretreatment air duct and a water spray device, and the water spray device is connected with the water mist pretreatment air duct , wherein the indoor return air enters the air conditioner unit through the water mist pretreatment air duct, and the air conditioner unit includes a room air conditioner box, a rotating mechanism and a refrigeration module, the rotation mechanism can drive the refrigeration module to rotate, and the refrigeration module It includes a compressor, a four-way reversing valve, an outdoor moisture storage heat exchanger, a dry filter, an expansion valve, an indoor moisture storage heat exchanger, and is connected through a refrigeration pipeline to form a closed system. The refrigeration module can operate in cooling mode and Operates in heating and humidification mode. The invention greatly improves the performance of the air conditioner, and solves the problems of the existing room air conditioner that the heat pump does not heat during defrosting in winter, the air conditioner cannot humidify in winter, and the leakage of condensed water and dripping noise are caused by improper handling during cooling in summer.

Description

technical field [0001] The invention relates to the technical field of room air conditioners, in particular to a room air conditioner based on a moisture storage heat exchanger and evaporation pretreatment. Background technique [0002] Currently, more than 1.2 billion room air conditioners are installed in the world, and their energy consumption accounts for about 4% of the world's energy consumption. The highest energy efficiency requirement) is 3.30. According to traditional air conditioning technology, the energy efficiency of air-cooled integral room air conditioners has reached a bottleneck that is difficult to break through. [0003] Furthermore, the existing room air conditioners will produce condensed water during cooling in summer, and if the condensed water is not drained smoothly, condensed water will leak. Noise pollution to downstairs residents. In addition, the existing room air conditioner is prone to frost during the heat pump heating in winter, and the ai...

[0003] Furthermore, the existing room air conditioners will produce condensed water during cooling in summer, and if the condensed water is not drained smoothly, condensed water will leak. Noise pollution to downstairs residents

In addition, the existing room air conditioner is prone to frost during the heat pump heating in winter, and the air conditioner cannot heat during the defrosting process. At the same time, the existing air conditioner cannot humidify in winter, and the room is dry in winter, which affects the comfort of the room

[0004] Patent document CN204555089U discloses a free-style fresh air air-conditioning refrigeration module device, including a frame, the frame forms a six-sided three-dimensional structure, a partition is also provided in the frame, an evaporator is arranged above the partition, and the partition There is a compressor and a condenser under the layer, and the evaporator, compressor and condenser are connected through pipelines and electronic expansion valves, bypass solenoid valves, one-way valves and four-way valves, and the bottom of the frame is equipped with pulleys, but this design still does not solve the problem of condensed water generated by the room air conditioner when cooling in summer
