Abstract

The invention discloses a fresh air system preheating device, a control method thereof, and a fresh air system. Fresh air system preheating device, including: fresh air preheating louver damper, fresh air louver damper, fifth damper, sixth damper, return air vent, fresh air preheating vent, fresh air vent, first temperature and humidity sensor, second Temperature and humidity sensor, fresh air fan, return air fan, shell, heat exchange core, air exhaust port, air supply port; the fresh air preheating louver damper is used to control the gas flow of the fresh air preheating port; the The fresh air louver damper is used to control the gas flow of the fresh air outlet; the preheating device of the fresh air system of the present invention can preheat the outdoor fresh air in a cold area to place the core to frost, and use the indoor return air to heat the outdoor fresh air, effectively utilizing Rate the heat in the room, and automatically adjust the size of the air outlet according to the control logic to ensure sufficient fresh air volume and maintain indoor air quality.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to a preheating device and a control method of a fresh air system, and a fresh air system. Background technique [0002] At present, people have higher and higher requirements for the quality of life. Therefore, many high-end residences are equipped with fresh air systems. According to national standards, the fresh air systems must be equipped with heat recovery devices. The full heat exchange core can recover both sensible heat and latent heat. Therefore, most of the fresh air ventilation devices are equipped with a full heat exchange core. Due to the cold winter climate in the northern region, when the indoor humidity is high, after heat exchange with the outdoor cold air, there will be serious frosting on the return air side of the core. It appears that the core cannot exchange heat, and the indoor air cannot be discharged at the same time. Therefore, it is imminent to...
