Problems solved by technology

Therefore, if full heat exchange is not required or the heat exchange effect is not obvious, unnecessary fan energy consumption will be greatly increased
In addition, this type of unit usually simply puts the evaporator and condenser in the same air duct, so that the temperature of the treated supply air is higher than the indoor temperature, although dehumidification will increase the additional indoor air conditioning load

Abstract

The invention discloses a multi-air-channel constant-humidity fresh air ventilator with joint control over temperature and CO2 and a working method thereof. The fresh air ventilator is provided with a fresh air port, an air return port, an air supply port and an air outlet, wherein double-layer air channels, a total heat exchanger, an air treatment module, an exhaust treatment module and a fan are arranged in the fresh air ventilator. According to the outdoor gas phase condition and the indoor air data measured by a temperature sensor and a CO2 concentration sensor, the fresh air ventilator has five working modes, namely a full fresh air mode in winter, a full fresh air mode in summer, a return air internal circulation mode in summer, a natural ventilation mode and a standby mode during full-year running time. According to the fresh air ventilator, the design of an upper air channel and a lower air channel is adopted, the fresh air entering the room and the return air are subjected to full heat exchange on the upper air channel just in the fresh air mode in summer and in the fresh air mode in winter, heat recovery is not needed in the other modes, and therefore the lower air channel bypasses the total heat exchanger, the system resistance is reduced, and the energy consumption of the fan is reduced.

Description

technical field [0001] The present invention relates to the field of indoor air purification equipment and technology, in particular to a device suitable for villas, apartments and other family residences, offices, classrooms and basements where there is no centralized air treatment system, which can realize humidification, dehumidification, purification, heat recovery, Constant humidity fresh air fan with multiple functions such as fresh air. Background technique [0002] In the middle and lower reaches of the Yangtze River in my country, from mid-June to early July each year is the rainy season, which lasts for nearly a month. During this period, the temperature is not high, generally at 20-28°C, but the relative humidity is very high, up to 80-95%. In the rainy season, people will not only feel stuffy, but also easily induce diseases and mildew of house items, which will not only affect the indoor air quality and comfort, but also cause harm to human health. With the imp...
