High temperature and moisture in the work place is a big concern in various industries. In extreme work condition with high temperature and moisture, work productivity is reduced because of increased human body and also it can lead to severe side effects. Hence it is necessary to create some personal cooling systems in order to these systems can keep body temperature in a suitable condition. These systems should be such that be used simply and easily in different places, nowadays some different types of personal cooling garments have been produced. One of which is cooling garment with vapor compression system. Preliminary researches on these garments focused more on some cases such as where cooling is exerted in body, intermittent cooling or be sequential tube types, tube liquid flow, garment productivity and other cases. And used fabric material in this garment is not being paid attention and mostly cotton fabrics are used in these garments. Also in previous models for these garments, these were produces as one layer and used tubes were located directly on skin surface. In this project, most applied fabric temperature transfer coefficients in this system have been investigated. In this investigation, first a vapor- compression system is constructed with a compressor having 1/8 vapor horse power and also and also refrigerator R-132a has been used as cooling liquid. Then fabric having various materials with knitting circular texture and is result from combination of tubler and Milano textures were produced and then a copper tube external and internal diameters inside these fabrics are 6 and 4 respectively. Eventually, these fabrics were placed in an environment in which temperature was set ranges 20 to 55 c so that these fabrics are studied in terms of temperature transfer coefficient and the best fabric type be selected in this view point. Also in this work, refrigerator flow was regulated and experiments have been conducted out in three stages. Finally by these experiments it was evident that nylon fabric has the most and acrylic fabric has the least temperature transfer coefficient among tested fabrics and also the more refrigerator mass flow, the more temperature transfer coefficient will be.
