Air total heat recovery fresh air system

Abstract

The invention discloses an air total heat recovery fresh air system which comprises an outdoor exhaust pipe, an outdoor air inlet pipe, a fresh air side wheel type filtering device, an exhaust side wheel type filtering device, a wheel type air total heat recovery heat exchanger, a rotating shaft, a wheel type shell, a fresh air pipe, an exhaust air pipe, an indoor air feeder, an indoor induced draft fan and a rotating shaft partition plate. According to the wheel type air total heat recovery heat exchanger, the cold, heat and water vapor of indoor exhaust air and outdoor fresh air are collected through rotation and a heat and humidity exchange coating. Due to the fact that the indoor exhaust air and outdoor fresh air alternately and reversely pass through the wheel type air total heat recovery heat exchanger, the heat and humidity exchange coating can collect and release the cold and heat quantity of air and water vapor through the temperature difference of the indoor exhaust air and the outdoor fresh air and the water vapor partial pressure difference, heat and humidity exchange can be carried out, and sensible heat can be recovered. And meanwhile, latent heat can be recovered, so that total heat recovery is realized.

Description

technical field [0001] The invention relates to the field of air heat exchangers and fresh air systems, in particular to an air full heat recovery fresh air system. Background technique [0002] The main pollutants that affect the indoor air environment include: formaldehyde, ammonia, benzene series, indoor colonies, carbon monoxide, carbon dioxide, PM 2.5 , PM 10 , TVOC (Total Volatile Organic Compounds) and SVOC (Semi-Volatile Organic Compounds), etc. Most of the pollutants volatilize faster and have higher concentrations at higher temperatures. At the same time, the concentration level of pollutants is closely related to the completion time of decoration, the environmental protection performance of materials used in decoration, the temperature and humidity of indoor environment, and the time of ventilation and ventilation. The concentration of volatile organic compounds decays with time, but even in old houses, there are still a lot of pollutants in the air. Good indoo...

AI Technical Summary

Problems solved by technology

However, the existing total heat recovery equipment will directly contact the hot and cold gases during the heat exchange process, which will cause secondary pollution and cannot achieve the effect of purifying the air, and the existing air heat recovery equipment cannot achieve real-time monitoring and control of indoor air cleanliness requirements
