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

Abstract

The invention provides a room air conditioner based on moisture storage heat exchanger and evaporation pretreatment. The room air conditioner comprises an air conditioner unit, a water mist pretreatment air duct and a water spraying device, wherein the water spraying device is connected with the water mist pretreatment air duct; indoor return air enters the air conditioner unit through the water mist pretreatment air duct; the air conditioner unit comprises a room air conditioner tank, a rotating mechanism and a refrigeration module, the rotating mechanism can drive the refrigeration module torotate; the refrigeration module comprises a compressor, a four-way reversing valve, an outdoor moisture storage heat exchanger, a drying filter, an expansion valve and an indoor moisture storage heat exchanger, which are connected through refrigeration pipes to form a closed system; and the refrigeration module can operate in a refrigeration mode and a heating humidification mode. According to the air conditioner, the performance of the air conditioner is greatly improved, and the problems of leakage and dripping noise of condensed water due to the fact that the existing room air conditionerdoes not heat when a heat pump defrosts in winter, and cannot perform humidifying in winter, and treatment during refrigeration in summer is inappropriate are solved.

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] At present, there are more than 1.2 billion room air conditioners installed in the world, and their energy consumption accounts for about 4% of the entire world's energy consumption. According to the requirements of GB12021.3-2010, the air-cooled integral room air conditioner has a level 1 refrigeration energy efficiency ( The maximum 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, existing room air conditioners will produce condensate during cooling in summer, and condensate leakage will occur due to poor drainage of condensate. If the condensate water is ...

Problems solved by technology

[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
