How to solve the problem of inaccurate temperature in laminar flow operating room
Release time:2019-10-30 source:
Laminar flow operating room is a key department of hospital, which requires high cleanliness and complex control. With the construction and development of modern hospital, it brings new and higher requirements to the daily maintenance and fault maintenance of air conditioning purification system. This paper describes several typical faults of air conditioning and purification system in laminar flow operating room, and provides corresponding treatment methods.
Temperature of laminar flow operating room is not accurate
Because the heat source in the operation room is mainly provided by the heating resistance, the temperature! Value is detected by the temperature sensor, the detection value is input to the display panel and the control system, and then compared with the set value, the start and stop of the multi-stage heating resistance contactor is controlled by the difference value for temperature adjustment. During the operation in winter, the temperature in the operation room was low. The possible reasons are as follows:
1. In case of this kind of fault, we should observe whether the temperature setting of the control panel in the operating room is low. If the setting value is low, properly raise the setting value. The temperature in the laminar flow operating room is generally set between 22-25 ℃. If there is no change in the panel temperature after adjusting the setting value for a period of time, then go to the computer room to check whether the heating system works normally. If the heating system is not correct The main reason for normal operation is that the overheat protection part of the control system acts, or the main circuit trips, etc. at this time, we will deal with it again to eliminate the fault.
2. If the temperature setting value and display value of the control panel in the laminar flow operating room are in the normal range, and the heating system is also in normal operation, but the temperature in the operating room is still low, the most likely cause is the aging of the temperature sensor, the test value is not consistent with the actual value, and the deviation is too large, then the replacement of the temperature sensor can eliminate the fault. When the temperature is high, the method is similar. In summer, we can also use the above ideas to eliminate the related problems of the refrigeration system.
