Problems solved by technology
However, for quite a long time in a year, transitional seasons are being dealt with. At this time, if the air conditioner is not turned on, there will be obvious discomfort in the room. At this time, the air conditioner or heating equipment must be turned on additionally, resulting in unnecessary consumption of energy consumption.

The invention relates to an operating method for a multi-level heat recovery fresh air treatment device. The operating method for the multi-level heat recovery fresh air treatment device relates to a summer mode, a winter mode and a transition season mode. Fresh air penetrates through a primary plate-type heat recovery device and the heat exchange is conducted between the fresh air and return air. The heat exchange is conducted when the fresh air penetrates through a precooling coiled pipe. In summer, after the fresh air penetrates through a recooling evaporator to be dehumidified, the fresh air penetrates through a fresh air condenser to be heated up. The fresh air penetrates through a wet film humidifier, and thus the needed humidity of the fresh air is reached. The fresh air penetrates through a secondary plate-type heat recovery device and the heat exchange is conducted between the fresh air and the return air. The fresh air enters an upper right cavity, is supplied through an air feeder and is distributed and sent into each room through an air distributor outside a fresh air outlet. The return air penetrates through the secondary plate-type heat recovery device and the heat exchange is conducted between the return air and the fresh air. The return air penetrates through the primary plate-type heat recovery device and the heat exchange is conducted between the return air and the fresh air. After the return air penetrates through an air outlet condenser and the heat recovery is conducted, the return air is exhausted to the outside. According to the operating method for the multi-level heat recovery fresh air treatment device, the flexible operating mode is adopted according to different seasons, so that the recovery utilization rate of energy is increased, and the energy consumption is reduced.
Description
technical field [0001] The invention relates to a working method of a multi-stage heat recovery fresh air treatment device, especially for the fresh air treatment of a central air-conditioning system. Background technique [0002] If the return air of the central air-conditioning system is directly discharged to the atmosphere, the energy of the return air is not recovered, resulting in a great waste of energy; in order to better save energy and reduce consumption, and realize the secondary utilization of energy, a central air-conditioning return is needed Wind energy recovery device; most of the heat recovery devices of existing central air conditioners use full heat exchangers to realize the heat exchange process, the heat exchange efficiency is relatively low, and the return air after heat exchange still contains a large amount of energy. Fans are not conducive to the efficient use of heat sources. [0003] The current domestic fresh air processor basically filters the f...
