Monitoring device of central air conditioner filter

Abstract

The invention discloses a monitoring device of a central air conditioner filter. The monitoring device comprises a box body, and an air inlet and an air outlet arranged on the box body, wherein a primary efficiency filter, a middle efficiency filter and a high efficiency filter are sequentially arranged at intervals in the box body between the air inlet and the air outlet; a differential pressure detector is arranged between a wind inlet of the primary efficiency filter and a wind outlet of the primary efficiency filter; a differential pressure detector is arranged between a wind inlet of the middle efficiency filter and a wind outlet of the middle efficiency filter; a differential pressure detector is arranged between a wind inlet of the high efficiency filter and a wind outlet of the high efficiency filter; and each differential pressure detector is connected with an alarm. The monitoring device disclosed by the invention can monitor whether various stages of filters namely the primary efficiency filter, the middle efficiency filter and the high efficiency filter are blocked or damaged in real time, can send alarm signals in time, has the characteristics of simple structure, high automation degree and strong practicability, and is beneficial for maintenance and overhaul works of a central air conditioner.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a monitoring device for central air-conditioning filters. Background technique [0002] At present, the filter devices used in central air-conditioning are generally composed of primary effect, medium effect and high-efficiency multi-stage filters. As the filters at all levels accumulate over time, debris and dust in the air slowly accumulate in the filter, making the filtering effect of the filter gradually decrease, or even fail. In order not to affect the normal use of the central air conditioner, special staff members are required to routinely check whether the filter is damaged or clogged, and then clean or replace the filter as appropriate. [0003] In the prior art, the staff judges whether the filter of the central air conditioner needs to be cleaned or replaced mainly by observing the amount of dust contained on the filter. This judgment method is prone to errors, and the degree ...

AI Technical Summary

Problems solved by technology

This judgment method is prone to errors, and the degree of intelligence is low, especially when the central air-conditioning filter is suddenly damaged or blocked during use, it is difficult to find it in the first time, which will affect the purification function of the entire air-conditioning system and cause room pollution. The cleanliness of the air inside does not meet the requirements
