Studies on the planning of the saving energy, the architectural building design and the air conditioning facilities for the prevention of the spray infection in the hospital

摘要病房空调是满足个性化需求和预防医院感染的必要条件。医院感染被认为与空调系统有重要关系。各种指导方针，例如CDC（2003年）、AIA（2001年）、ASHRAE（2003年）和HEAJ （HEAS-02-2004年）规定，适当的空调应保持医院每个区域的空气清洁，以达到卫生目的，并控制医院内的压力和气流。本研究是为了掌握病房环境的实际情况，明确理想的病房环境，并讨论支持该环境的空调系统，并报告本次调查结果以及病房温度和湿度测量，以及空气质量（真菌和细菌数量）数据。并了解了干燥剂空调系统的特性，从而达到降湿的目的。结论通过对我院病房暖通空调系统的调查，90%以上的医院采用了FCU、Multi-AC等室内空气循环设备。此外，发现90%以上的医院采用冷却除湿。这样的系统允许真菌的产生和繁殖伴随着冷凝。根据现场测量，在中期季节开始时，FCU吹出的空气和病房空气中的微生物（主要是真菌）明显增加。为了避免这种危险，重要的是通过降低FCU供水温度来抑制真菌的产生和伴随冷凝的繁殖，并通过安装最终过滤器来抑制真菌从FCU扩散到房间。在能耗模拟的结果中，发现了干燥剂空调系统对回风进行再利用的特点，降低了能耗。但仅使用干燥剂空调系统，将设计湿度降至前提条件需要一定的时间。少

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
