Trial production of new intelligent temperature-controlled composite cooling vest for ship engineers and evaluation of their cooling effects
Aiming at the problem that the cooling effect of the first generation cooling vest was not obvious when the ambient temperature was above 40℃,the core component,battery and cooling suit of the host of the temperature control system were optimized,and the new cooling vest,a new type of intelligent temperature-controlled composite cooling vest,was made,in order to reduce the heat load of ship engineers during operation.Ten subjects were selected to wear the new intelligent temperature-controlled composite cooling vest in working and non-working state under the high temperature simulated environments of 37,41 and 45℃to test and evaluate their cooling effects.The results showed that,the new intelligent temperature-controlled composite cooling vest still had a significant cooling effect in ambient temperatures above 40℃,and in different experimental ambient temperatures,the physiological indexes of the subjects wearing the new cooling vest in the working state were significantly and very significantly reduced,and the subjective comfort scores were also lower than those of the subjects wearing the new cooling vest in non-working state(P<0.05),and the human comfort was improved.The new cooling vest is reasonably designed,which can effectively reduce the human body heat stress load and has a good cooling effect.
