    来源:http://www.sdyhrs.com 浏览: 发布日期:2020-05-20
      我们都知道,手术室净化对于医院来说是非常重要的,空气净化的选择也是讲究的。如何选择合适的手术室净化空调系统的净化手术室,包括新鲜空气负载和室内湿负荷,和空调机组进行室内显热负荷和冷负荷减少,同时为了避免空调机组除湿再热冷管的过程,和新鲜空气机组再热实际上是使用冷凝器排放的废热。
      As we all know, operating room purification is very important for hospitals, and the choice of air purification is also exquisite. How to select a suitable operating room for purifying the air conditioning system, including fresh air load and indoor wet load, and reduce the indoor sensible heat load and cooling load of the air conditioning unit, and at the same time, in order to avoid the process of dehumidification and reheating of the air conditioning unit and the reheating of the fresh air unit are actually the waste heat discharged by the condenser.
      (1)采用二次回风系统,降低运行成本
      (1) Adopt secondary return air system to reduce operation cost
      医院净化空调系统风量大,送风温差很小的特点,特别是Ⅰ、Ⅱ手术室层流病房,送风温差很小,通常只有1℃~ 2℃,手术室的净化,使用传统的一次回风系统,新鲜的空气冷却除湿与回风混合后应该有足够的热量加热的空气供给条件下,这部分的加热和冷却除湿过程又存在严重的冷热补偿问题,导致运行成本和能源浪费的增加。
      The air volume of the hospital purification air conditioning system is large, and the temperature difference between the air supply and the air supply is very small, especially in the laminar flow ward of the I and II operating rooms, the temperature difference between the air supply and the air supply is very small, usually only 1 ℃ ~ 2 ℃, for the purification of the operating room, using the traditional primary return air system, the fresh air cooling dehumidification and return air mixing should have enough heat to heat the air supply, In this part of the heating and cooling dehumidification process, there are serious hot and cold compensation problems, which lead to the increase of operating costs and energy waste.
      在工程的实际应用中,我们经常采用一次回风与二次回风比例固定的二次回风方式,利用二次回风再热来降低再热负荷。同时,冷盘管处理后的风量减小,冷却量减小。手术室净化系统由于室内负荷的变化,不需要再热复合或只需少量再热即可微调送风温差,足以满足室内温湿度调节的需要。因此,在手术室净化中,二次回风的使用可以达到良好的节能效果,是一种有效的节能方法,在工程实践中得到了广泛的应用。相同级别相同大小的Ⅰ手术室,新鲜空气负载、二次回风系统节约55%的空调机组,冷却能力节省80%以上的电加热。因此,在手术室净化中,二次回风系统是节能的有效途径之一。当然,二次回风系统主要适用于风量大、温差小、室内负荷稳定的高层手术室和层流病房。
      In the practical application of the project, we often use the fixed proportion of primary return air and secondary return air to reduce the reheat load. At the same time, the air volume and cooling capacity of the cold coil tube decrease after treatment. Due to the change of indoor load, the purification system in operating room can adjust the temperature difference of air supply without reheating or with a small amount of reheating, which is enough to meet the needs of indoor temperature and humidity regulation. Therefore, in operating room purification, the use of secondary return air can achieve good energy-saving effect, is an effective energy-saving method, and has been widely used in engineering practice. In operation room I of the same grade and size, 55% air conditioning units are saved for fresh air load and secondary return air system, and more than 80% electric heating is saved for cooling capacity. Therefore, the secondary return air system is one of the effective ways to save energy in operating room purification. Of course, the secondary return air system is mainly suitable for high-rise operating rooms and laminar flow wards with large air volume, small temperature difference and stable indoor load.

      (2)采用新鲜空气深度除湿集中处理
      (2) Deep dehumidification and centralized treatment with fresh air
      空气除湿的深度设置两层表一般冷,个液位计与空调冷7℃冷冻水,将被视为空气湿度的室内空气露点L1点,然后用直接蒸发式冷线圈实现二级除湿,L2点处理,蒸发器用于制冷除湿、冷凝器用于除湿再热,将空气的湿度作为送风空气的露点处理到L1以下。新鲜空气承担所有的湿负荷,手术室的净化,包括新鲜空气负载和室内湿负荷,和空调机组进行室内显热负荷和冷负荷减少,同时为了避免空调机组除湿再热冷管的过程,和新鲜空气单位再热实际上是使用冷凝器排放的废热。在手术室净化中,新风集中深层除湿可节省空调机组25%的制冷量,节省100%的电再热。综合节能达到50%~60%。
      The depth of air dehumidification is generally cold with two layers of meters. The first level gauge and the central air conditioner cool 7 ℃ chilled water, which will be regarded as the indoor air dew point L1 of air humidity. Then, the direct evaporation type cooling coil is used to realize secondary dehumidification, L2 point treatment. The evaporator is used for refrigeration dehumidification, and the condenser is used for dehumidification and reheating, and the air humidity is treated as the dew point of air supply to below L1. Fresh air bears all the wet loads. The purification of operating room, including fresh air load and indoor wet load, and the indoor sensible heat load and cooling load reduction of air conditioning unit. At the same time, in order to avoid the process of dehumidification and reheat of air conditioning unit, the waste heat discharged by condenser is actually used. In operating room purification, centralized deep dehumidification of fresh air can save 25% of cooling capacity of air conditioning unit and 100% of electric reheat. The comprehensive energy saving is up to 50% ~ 60%.
      因此,手术室深度除湿净化新风深度除湿也是一种有效的节能技术措施,但这种形式应根据冷热源的条件及所在地区的特点来确定。首先,新风深度除湿适用于低温冷源的情况。如果没有条件,就无法达到除湿效果。此外,手术室净化新风深度除湿适用于南方潮湿地区,不适用于寒冷地区和寒冷地区。
      Therefore, the deep dehumidification of fresh air in operating room is also an effective energy-saving technical measure, but this form should be determined according to the conditions of cold and heat sources and the characteristics of the area. First of all, deep dehumidification of fresh air is suitable for low temperature cold source. If there is no condition, the dehumidification effect cannot be achieved. In addition, the operating room purification fresh air deep dehumidification is suitable for the humid areas in the south, not for the cold areas and cold areas.
      选择适用于净化空调系统,应用二次回风系统,使用的方法,如除湿和冷却空气深度清洁工程公司净化空调系统的设计可以被认为是应用程序的过程中有效的节能技术措施,在实践中,根据项目的具体特点,地区,冷热源选择和应用。
      The selection of the methods applicable to the purification air conditioning system and the application of the secondary return air system, such as the design of the purification air conditioning system of dehumidification and cooling air deep cleaning engineering company, can be considered as the effective energy-saving technical measures in the application process. In practice, according to the specific characteristics of the project, the region, the selection and application of cold and heat sources.
