Embodiment 1

[0034]Add valves to the fresh air duct, exhaust duct and return air duct respectively, close the valves of the fresh air duct and exhaust duct, adjust the valve of the return air duct to increase the return air volume, ensure that the total air supply volume remains unchanged, and form a temporary closure of the internal circulation of indoor air formula system. In the case of bad outdoor air such as smog and sandstorms, the invention partially transforms the air conditioning system by setting electric valves and linkage control, and converts the hybrid air conditioning system into a temporary closed system to realize the temporary isolation of indoor and outdoor dirty air . When the outdoor pollution index decreases, it will be converted to a hybrid air conditioning system through the linkage control of the fresh air valve, exhaust valve, return air valve and air conditioning fan.

[0035] The present invention involves two situations: through the control of the linkage cont...

Embodiment 2

[0037] The air-conditioning fan linkage device prepared by the present invention has the following operating conditions: when the outdoor PM2.5 concentration sensor detects that the outdoor PM2.5 concentration exceeds 0.075mg / m3, that is, when the outdoor air quality is not up to standard, close the fresh air valve and exhaust air. Valve, open the large return air valve, the system temporarily closed operation. After running for a period of time, when the indoor carbon dioxide concentration sensor detects that the indoor carbon dioxide concentration is greater than 0.1%, it will force open the fresh air valve, the exhaust valve, and close the return air valve. Calculate the minimum fresh air ratio, the opening of the exhaust valve is calculated based on the indoor air pressure reaching 5-10Pa, then open the fan and the water valve 18 of the surface cooler, and then open the water wheel purifier and electrostatic filter, so as to ensure the quality of fresh air. After the syste...

Abstract

The invention relates to a fresh air and return air collaborative air supply haze-preventing air conditioner system. The system comprises an air conditioner device and an automatic control device. The air conditioner device comprises a fresh air valve, a return air valve, an exhaust valve, a louvre blade wheel washing cleaning device and an electrostatic filter. The automatic control device comprises an exhaust pipeline, a fresh air pipeline and a return air pipeline. The exhaust pipeline and the fresh air pipeline communicate with a room. The fresh air pipeline enters the room and is then connected with an air conditioner indoor unit. The air conditioner indoor unit is connected with an air supply pipeline. The return air pipeline is connected with the air conditioner indoor unit. The fresh air valve is arranged on the fresh air pipeline on a front section of the air conditioner indoor unit in the room, the exhaust valve is arranged on the exhaust pipeline outside the room, and the return air valve is arranged on the return air pipeline. The fresh air and return air collaborative air supply haze-preventing air conditioner system can be used for temporarily isolating indoor air and outdoor dirty air under the condition of severe outdoor air such as haze and sand storm, the outdoor dirty air is prevented from entering the room through the air conditioner system, and therefore cleanliness of the indoor air is ensured.

Description

technical field [0001] The invention belongs to the field of air-conditioning equipment, in particular to systems for severe weather such as smog and sandstorms, and in particular relates to an anti-haze air-conditioning system and a working method thereof in which fresh air and return air are cooperatively supplied. Background technique [0002] In recent years, with the development of my country's economy, the rapid growth of urban population and the acceleration of urbanization, air pollution problems such as smog have become the focus of widespread attention. According to reports, in November 2015, from 3:00 a.m. on the 8th to 1:00 a.m. on the 9th, the air quality in Shenyang, Liaoning Province was “off the charts” for 22 consecutive hours, with a peak value exceeding 1,000 micrograms per cubic meter. In view of air pollution problems such as smog, there is an urgent need to propose anti-smog air conditioning system renovation projects. [0003] Most of the traditional ...
