保护工人免受热应激环境的影响一直是行业、劳工组织和政府关注的问题。最近提出的OSHA热应力标准证明了这种担忧，该标准已成为行业采取行动的最有效推动力。ASHRAE文献中详细记录了设计全容积空调系统的程序；然而，分层和局部冷却系统的设计人员还存在不足，缺乏可用的基本信息。本文论述了点冷却系统的设计。其目的是确定设计过程所需的基本信息。文中还讨论了如何将这些信息用于以最低能耗设计局部冷却系统的最终目标。引文:德克萨斯州休斯顿ASHRAE学报第88卷第1部分

Protection of workers against exposure to heat stress environments has been a concern of industry, labor organizations, and government. Such concern was demonstrated in the recently proposed OSHA Heat Stress Standards, which have acted as the most effective prod to action by industry.The procedure for designing a total volume air-conditioning system is well documented in ASHRAE literature;however, there are deficiencies and a lack of basic information available to designers of stratified and spot cooling systems. This paper deals with the design of spot cooling systems. Its objective is to identify the basic information needed for the design process. It also discusses how such information can be used with the ultimate objective of designing the spot cooling system with minimum energy usage.
