医院弱电竖井高温控制措施探析

Analysis of High Temperature Control Measures for Weak Current Shaft in Hospitals

弱电竖井内温度随着智能化系统设备的增多而不断升高,为了确保设备正常运行,采用经济、可行、安全、稳定的措施将竖井内温度降下来,是大部分弱电竖井改造中的难题之一。该文以北京某医院医疗综合楼弱电竖井为试验点,从施工预算、施工周期、施工难度、耗电量、维护成本、损坏后影响、调控范围、试验性等方面对比了空调制冷降温、通风换热降温,并选择通风换热方案进行试验。试验结果表明:通风换热的方式能够有效降低竖井内温度;与正压送风相比,双风机送排风更适合该医院。

The temperature inside the weak current shaft continues to rise with the increase of intelligent system equipment.In order to reduce the temperature in the shaft and ensure the normal operation of the equipment by economical,feasible,safe and stable measures is one of the difficulties to most weak current shaft renovations.This article takes the weak current shaft of a medical complex building in a hospital in Beijing as a pilot,and compares air-conditioning cooling and ventilation and heat exchange in terms of construction budget,construction period,construction difficulty,power consumption,maintenance cost,impact after damage,control scope,and experimental nature.It selected a ventilation and heat exchange plan for testing.The test results showed that the ventilation and heat exchange method can effectively reduce the temperature in the shaft;compared with positive pressure air supply,dual-fan air supply and exhaust is more suitable for this hospital.
