Fresh air purification unit system and operation control method thereof

Abstract

The invention discloses a fresh air purification unit system. The unit system comprises a main body and a full-heat heat exchanger arranged in the main body. A purification module, a heat exchange module, a second electric heating module, a humidification module, a blower and an air supplying opening are arranged in sequence along an air supply direction of an air supply channel. Based on monitored inlet air temperature T3, indoor dew point temperature Tw, outdoor ambient temperature T4, supply air temperature T2, indoor temperature T1, indoor humidity H1, indoor PM2.5 and indoor CO2 and otherparameters, a series of control actions are carried out on the unit system to ensure that the indoor environment is at a reasonable indoor temperature, humidity, cleanliness and oxygen content, and to create a comfortable indoor environment. At the same time, the unit system is activated and dynamically adjusted on demand, can save more energy, and is reliable.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a fresh air purification unit system and an operation control method thereof. Background technique [0002] Fresh air equipment is widely used in homes, hotels, office buildings, villas and other places. The fresh air fan can supply fresh air to the room and discharge the dirty air in the room, solve air-conditioning problems and is widely used in various places. However, due to the large temperature difference between indoor and outdoor, the load of the fresh air heat exchanger is large and wastes energy. Although a full heat exchanger is added , in summer, part of the cold energy can be recovered, but part of the energy is wasted, especially in winter, when the outdoor temperature is very low, especially in the northern region, the outdoor temperature is lower than -10 degrees, and it is easy to freeze in the total heat exchanger , and block the total heat exchanger, ...

AI Technical Summary

Problems solved by technology

However, the purifier spends most of its time in a confined space. If it lasts for a long time, it is easy to cause symptoms such as hypoxia in the room, and the experience is very bad.

[0004] Air conditioners are widely used in various places to solve people's requirements for temperature control, but staying in air-conditioned rooms for a long time will cause air-conditioning diseases such as dirty air and lack of oxygen.
