Embodiment Construction
[0046] The following is attached figure 1 To attach Figure 7 The present invention is further described in detail with specific examples.
[0047] After the existing air-conditioning dust detection system detects that the inhalable particulate matter PM10 in the air-conditioning system does not meet the standard, it sends out an audible and visual alarm to remind the air-conditioning owner to clean the air-conditioning system. But in fact, the existing air-conditioning dust detection system cannot determine the specific reason why the inhalable particulate matter PM10 in the air-conditioning system does not meet the standard, that is, it cannot judge that the inhalable particulate matter PM10 comes from the dust inside the central air-conditioning system or from the outdoor fresh air outlet (or Indoor return air outlet). Therefore, it is impossible to provide decision-making basis for the owner of the air conditioner, and the owner of the air conditioner cannot judge whethe...

The invention relates to the field of air conditioning systems, and provides a central air conditioning system PM10 index detection system and method. The detection system comprises a dust detection device, an accumulated dust washing device and a control unit, the dust detection device is used for detecting the dust concentration value in an air-conditioning duct where each detection point is located; the accumulated dust washing device enables accumulated dust on the inner wall surface of the air-conditioning duct to flow through the dust detection device under rotational flow entrainment; and the control unit is used for comparing a first average value with a PM10 early warning critical value and a cleaning and disinfection critical value correspondingly, comparing a difference value between the first average value and a second average value with a PM10 concentration change limit difference value, and carrying out sound-light alarm on the accumulated dust washing device according to a comparison result. According to the central air conditioning system PM10 index detection system and the method, the concentration of the accumulated dust in the air-conditioning duct can be effectively detected, so that the condition that the inhalable particulate matter PM10 comes from the outdoor or the accumulated dust in the air-conditioning duct can be accurately judged, and a decision is provided for cleaning and disinfection of related parts of an air-conditioning system.
Description
technical field [0001] The present invention relates to the technical field of air-conditioning systems, in particular to a centralized air-conditioning system PM 10 Indicator detection system and method. Background technique [0002] Air conditioning is an important technical means to meet and maintain suitable indoor temperature and humidity, especially in public buildings, the centralized primary air return air conditioning system is the most widely used. The hygienic condition of the air supply of the air conditioner greatly affects the air cleanliness of the air conditioner. Unsanitary air supply will promote the growth of Legionella and pollute the entire indoor air. Therefore, when the quality of the air supply is not up to standard, it is necessary to clean and disinfect the relevant parts. [0003] In the current specification, although there are certain regulations and operational requirements for the inspection, cleaning and disinfection of the air supply air su...
