Experimental study on cooling effect and improving comfort of cooling vest

Abstract

In order to provide a comfortable working space in a warm or hot environment, it is necessary to cool these spaces to consume energy. In the context of global warming, the ability to provide comfort is becoming more and more challenging. With the increase of energy consumption, the demand for cooling is also increasing [1]. In previous studies, different types of individual and local cooling methods have been used to reduce the thermal stress of outdoor workers [1-7] and improve the comfort of indoor workers in office and commercial buildings. Local cooling can improve the macro climate air temperature, because the microclimate of workers is cooled, so the space air conditioning system needs less energy [1]. In addition, the thermal comfort of the transition space can be improved by using local passive cooling technology.
