What is the impact of the humidity in the clean operating room that does not meet the specified requirements? Ed pointed out that if the indoor temperature is not reached, it will affect the overall environment of the clean operating room and normal operation. The following is an introduction to the requirements for the detection of room temperature humidity in hospital clean operation and the solutions and existing problems in clean operation room.
Detection requirements of room temperature and humidity in hospital clean operation
1. The working condition in summer shall be tested in the hottest month of the local year, and in winter shall be tested in the coldest month of the local year.
2 the indoor temperature and humidity shall be measured as the center point 0.8m high from the ground, and the test results shall meet the requirements. The testing instrument is a digital temperature and humidity measuring instrument which can display one decimal place. The provisions of this clause are not applicable to the requirements of temperature and humidity fluctuation range.
3 after the indoor temperature and humidity are measured, the outdoor temperature and humidity shall be measured at the same time.
Solution of humidity in clean operating room and existing problems
With the rapid progress of society, we need to make progress in all fields at the same time. Hospital is a place that needs development most, and development is to solve problems. There are some problems in dehumidification of air conditioning system in clean operating room, especially in the transitional season. In order to solve these problems, an air conditioning system of operating room is proposed, which can separate refrigeration and dehumidification. Through analysis and comparison, common air conditioning dehumidification schemes and existing problems in domestic operating rooms.
Generally, the required temperature in the operating room is 22-25 ℃, and the relative humidity is 40% - 60%. Some special types of operation may require lower relative humidity. At present, the common practice in humidity control of operating room air conditioning in China is (hereinafter referred to as the traditional scheme): after the fresh return air is mixed, it is cooled and dehumidified by the surface cooler, and the relative humidity at this time is generally about 90%, which is far from the humidity requirements of operating room, and then it is reheated by the electric heating pipe to reduce the relative humidity. The humidity of this method meets the requirements, but it inevitably has the following problems:
1. Increase in initial investment: considering that electric heating will offset part of the unit's cooling capacity, it is necessary to reserve enough cooling performance margin in the design and selection of air conditioning unit, resulting in an increase in initial investment in equipment. For example: the operating room cooling load of a hospital is 16 kW, but the air conditioning system needs to match about 6 kW of electric heating to meet the requirements of relative humidity, so the cooling capacity of the selected air conditioning unit is 22 kW.
2. Increase in energy consumption: when the wet load in the operating room is large, the electric heating should be turned on, so that the cold and heat will offset each other and the energy consumption will increase.
3. Reduction of equipment utilization rate: when the wet load in the operating room is small and the electric heating is not needed to control the relative humidity, the equipment is considered according to the most unfavorable working condition in the design, and the actual load is small at this time, the equipment utilization rate is reduced. At the same time, the long-term low load operation will cause the surge phenomenon of the refrigeration host.
4. It is difficult to solve the problem of humidity under specific circumstances: when the cooling load in the operating room is small and the humidity load is large, such as the transitional season in the south. In this case, in order to meet the temperature requirements and improve the temperature of chilled water, but in this way, the dehumidification capacity of the unit will be further reduced, the moisture content of the air can not be reduced, and the humidity problem can not be solved.
