Air purifier for indoor ventilation purification and circulation purification

Abstract

An air purifier for indoor ventilation purification and circulation purification comprises an air purifier box, an outdoor air duct, an outdoor air inlet, a room A return air inlet, an indoor return air inlet, a room A air supply outlet, a mixed-air duct, a fan, a purifier I and a purifier II. The air purifier for the indoor ventilation purification and the circulation purification is characterized in that a room B return air inlet and a room B air supply outlet can be further arranged apart from the room A return air inlet and the room A air supply outlet; the outdoor air duct is connected with the outdoor air inlet, the room A return air inlet and the room B return air inlet are communicated with the indoor return air inlet, one side of the mixed-air duct is connected with the outdoor air inlet and the indoor return air inlet, the other side of the mixed-air duct is connected with one side of the purifier I, the other side of the purifier I is connected with one side of the fan, the other side of the fan is connected with one side of the purifier II, and the other side of the purifier II is connected with the room A return air supply outlet and the room B air supply outlet. The air purifier can be connected to a temperature and humidity regulator, so that the whole indoor air can meet comfort requirements for purification, oxygen enrichment and moderate temperature and humidity.

Description

Technical field [0001] The invention relates to an air purifier for indoor ventilation purification and circulation purification, in particular to an air purifier that can be shared by two rooms, can introduce purified outdoor air into the room, circulate and purify the indoor air, and can also adjust the air supply. Air purifier for temperature and humidity. Background technique [0002] Factors affecting indoor air quality include indoor pollutants, outdoor pollutants and high CO2 concentration. The solution to indoor air pollution is: ① Open windows for ventilation. Opening windows for ventilation can not only introduce fresh oxygen into the room, but also dilute and discharge it. Indoor polluted air, but window ventilation is not only limited by climate, but also by outdoor air pollution; ②Mechanical ventilation, mechanical ventilation can not only introduce fresh oxygen into the room, but also dilute and discharge indoor polluted air. The most popular products are one-...

AI Technical Summary

Problems solved by technology

Its disadvantages are: ① It cannot prevent pollutants from entering the room from the outside; ② It cannot reduce the concentration of indoor CO2, and the indoor oxygen content is low; ③ When the room temperature is slightly lower, the human body will feel air-cooled due to the flow of air

Its disadvantages are: ① It cannot effectively purify the air entering the room; ② The indoor air is forcibly discharged, and the indoor heat is also forcibly discharged, which has a great impact on the indoor temperature and cannot operate around the clock; ③ The installation cost of the exhaust duct is high and difficult Large, need to destroy the decoration to install; ④ Hidden installation, difficult maintenance

Its disadvantages are: ① It cannot efficiently purify the air entering the room; ② The long air supply pipe is easy to accumulate dust and bacteria, causing secondary air pollution; ③ When the outdoor temperature is continuously lower than minus 5 degrees, the heat exchanger will produce condensation. Due to the phenomenon of frost, it cannot operate around the clock; ④The installation of air supply ducts and exhaust ducts is costly and difficult, and the decoration needs to be destroyed to install; ⑤Concealed installation, difficult maintenance

Its disadvantages are: ① The ratio of fresh air volume and return air volume can be adjusted by adjusting the fresh air valve and return air valve, while the fresh air machine adjusts the fresh air volume and return air volume at the same time through the air volume configuration regulator, and the structure is complicated; ② There is only one return air outlet and the air supply The air outlet cannot efficiently use the purification device; ③The temperature and humidity of the air supply cannot be adjusted, so it cannot operate around the clock
