项目摘要

ABSTRACTPatient room air conditioning is required to meet individual needs and prevent hospital infection. Hospital infection is believed to have an important relationship with the air conditioning system. Various guidelines, for example, CDC (2003), AIA (2001), ASHRAE (2003) and HEAJ (HEAS-02-2004), prescribe that appropriate air conditioning shall keep the air clean in each area of a hospital for sanitation, and control pressure and air currents within the hospital.This study was conducted in order to grasp the actual conditions of the patient room environment, to clarify the ideal patient room environment, and to discuss air conditioning systems for supporting this environment And this reports the results of this survey as well as patient room temperature and humidity measurement, and air quality (number of fungi and bacteria) data. And to know the characteristic of the desiccant air conditioning system is able to decrease of humidity.CONCLUSIONSBased on the survey on HVAC systems i … More n patient rooms, indoor air circulating equipment, such as FCU and Multi-AC, are being utilized at more than 90% of hospitals. In addition, more than 90% of hospitals were found to use cooling dehumidification. Such systems allow fungi generation and propagation to accompany condensation.Based on field measurements, microorganisms (mostly fungi) in FCU blown air and in patient room air were increased markedly at the beginning of the intermediate season. To avoid this type of danger, it is important to suppress fungi generation and propagation accompanying condensation by reducing the FCU water supply temperature, and to suppress fungi dispersion from the FCU into the room by installing a final filter.In the result of the simulation of the energy consumption, the characteristics of the desiccant air conditioning system which reuse of the returned air, decrease the energy consumption. But by only use of the desiccant air conditioning system, it takes the time to decrease the design condition of humidity to the prerequisite condition. Less

摘要为了满足病人的个人需要和防止医院感染，需要对病人房间进行空调。医院感染被认为与空调系统有着重要的关系。各种准则，例如CDC（2003年）、AIA（2001年）、ASHRAE（2003年）和HEAJ（HEAS-02-2004）中规定，适当的空调应保持医院各区域的空气清洁，以达到卫生目的，并控制医院内的压力和气流。阐明理想的病房环境，并讨论支持这种环境的空调系统。本文报告了这次调查的结果以及病房温度和湿度测量和空气质量（真菌和细菌数量）数据。了解除湿空调系统的降湿特性。 ...更多信息在病房中，90%以上的医院使用室内空气循环设备，如FCU和Multi-AC。此外，超过90%的医院被发现使用冷却水。根据现场测量，FCU吹出空气和病房空气中的微生物（主要是真菌）在中间季节开始时显著增加。为了避免这类危险，通过降低FCU的供水温度来抑制真菌的产生和繁殖，并通过安装最终过滤器来抑制真菌从FCU扩散到室内，这是很重要的。在能耗模拟的结果中，除湿空调系统的特点是回风口的再利用，降低了能耗。但单纯采用除湿空调系统，将设计湿度降到必要条件需要一定的时间。少
