一种新型高效环保空调服的提出

The Introduction of a New Effective Cooling Vest

文中回顾了空调服概念的提出和发展历程,着重介绍了Green系统、液体循环空调服、PCM空调服等具有代表性的空调服,集中论述和比较了各个系统之间的优势和不足。在已有空调服的基础上,文中提出一种新型空调服。它利用涡流管制冷的基本原理,由电池组驱动小型空压机为涡流管提供压缩空气,涡流管产生的冷气进入空调服,并通过喷深系统喷射到人体躯干的热敏感部位,达到高效制冷的目的。与已有的几种空调服相比,新型空调服在调节性能、制冷效果、使用时间等方面都具有优势。除此之外,新型空调服不采用任何有毒材料或制冷剂,是一个较为完善的、绿色环保的解决方案。文中根据人体热力学实验结果,计算出新型空调服系统所需制冷量,并以此制冷量为基础,本着便携、高效的原则,对空调服核心部件-涡流管、空压机、电池组等提出技术要求,未来的研究方向将围绕着部件选型、实验验证制冷效率、搭建产品平台等方面展开。

This paper reviews the development of cooling vest, and introduces some typical cooling vest system, such as Green System, circulatory cooling vest and PCM cooling vest. The advantages and disadvantages of those systems are compared and contrasted. Based on existing systems, a new cooling vest is presented, which utilizes the theory of vortex tube ; producing compressed air by a small air compressor driven by battery pack. The cold air coming out of the vortex tube goes into the vest, and then spread to the thermal sensitive area of human trunk through high - speed nozzles. Compared to the existing cooling vest products, the new cooling vest adopts non - poisonous material and refrigerants, which is a complete and environmental solution. The overall refrigerating effect of the cooling vest was calculated by using human thermal experiment, and then the specifications of vortex tube, air compressors and battery pack were determined. The future study will focus on the equipment selection, experimentation of cooling effect, product commercialization, etc.
