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 fresh air treatment device with a secondary heat recovery function. The fresh air treatment device is characterized in that a forced draught blower is arranged in an air inlet channel, and an exhaust fan is arranged in an air exhaust channel; a plate type heat recovery device is arranged at the intersection position of the air inlet channel and the air exhaust channel; and a second condenser for heat recovery is arranged at the position, behind the plate type heat recovery device, in the air exhaust channel. Direct heat exchange can be carried out on fresh air and exhausted air, and the exhausted air obtained after heat exchange can be thermally recovered.

Description

technical field [0001] The invention relates to a fresh air treatment device with secondary heat recovery, especially for the fresh air treatment of 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 processor basically filters the fresh air and sends it di...
