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.
[0004] At present, the dry-type terminal system represented by the radiant terminal is becoming the mainstream of the future central air-conditioning system due to its high health and comfort. Problems such as condensation have appeared in the application, and the deep dehumidification technology for fresh air has become an urgent issue

Abstract

The invention relates to a working method of a secondary heat recovery fresh air processing device. The working method comprises a summer mode, a winter mode and a transition season mode, wherein the summer mode comprises an energy-saving mode, a dehumidification mode and a normal mode; when working in the winter mode, the secondary heat recovery fresh air processing device works in a minimal fresh air volume mode to automatically detect the concentration of indoor CO2, and the required fresh air volume can be adjusted; and the transition season mode comprises a normal transition season mode, a transition season refrigerating mode, a transition season dehumidification mode and a transition season heating mode.

Description

technical field [0001] The invention relates to a working method of a secondary heat recovery fresh air processing device, in particular to a working method of a fresh air processing device used in a central air-conditioning system. Background technique [0002] If the exhaust air of the central air-conditioning system is directly discharged to the atmosphere, the exhaust energy 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 exhaust 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 exhaust 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 processo...
