Method and device for automatically detecting variable air volume system in a hospital

Abstract

The invention relates to a method and device for automatically detecting variable air volume systems in a hospital. The method includes the following steps: S1: obtaining an air supply temperature ofan variable air volume box, an indoor temperature, an indoor relative humidity, an air volume of the variable air volume box, a main air duct pressure, an indoor dew point temperature and an air valveopening signal in real time S2, calculating an air supply temperature change rate, an indoor temperature change rate, an indoor relative humidity change rate, an air volume change rate of the variable air volume box and a main air duct pressure change rate; S3, analyzing and judging the air supply temperature of the variable air volume box, the indoor temperature, the indoor relative humidity, the air volume of the variable air volume box, the main air duct pressure, the air supply temperature change rate, the indoor temperature change rate, the indoor relative humidity change rate, the air volume change rate of the variable air volume box, the main air duct pressure change rate and the indoor dew point temperature according to preset rules, outputting corresponding control signals according to the analysis and judgment results. The method and device for automatically detecting the variable air volume systems in the hospital effectively distinguish the variable air volume systems thatare going to fail in a higher probability or have been failed already and find out the cause of failure timely and efficiently.

Description

technical field [0001] The invention relates to the technical field of hospital variable air volume systems, and more specifically, to an automatic detection method and device for hospital variable air volume systems. Background technique [0002] For the air quality requirements of the hospital, especially whether the variable air volume air conditioning system (VAV, Variable Air Volume) in the office area of ​​the hospital can operate normally, and whether the cooling capacity of the controlled space area can meet the relevant functional requirements during daily maintenance appears to be particularly important. [0003] If the traditional variable air volume air conditioning system fails, it is usually only after on-site user complaints or regular inspections that it can be checked and discovered in a targeted manner. It lacks timeliness, sacrifices the comfort of the air conditioner, and may also cause a great waste of energy and resources. Contents of the invention ...

[0003] If the traditional variable air volume air-conditioning system fails, it is usually only after on-site user complaints or regular inspections that it can be checked and found in a targeted manner. It lacks timeliness, sacrifices the comfort of the air conditioner, and may also cause a great waste of energy and resources.
