Experimental study on the cooling performance of medical protective clothing coupled with phase-change cold storage materials

Abstract

To solve the problems of poor cooling and moisture permeability of the normal medical protective clothing. A scheme of coupling the phase change cold storage material 1-dodecanol to normal medical protective clothing was proposed. Then the effect of phase change cold storage material on the cooling performance of the normal medical protective clothing internal microenvironment was studied under different conditions. The results showed that compared with normal medical protective clothing, when frontline medical workers wore the phase change medical protective clothing for light labor at 24℃ of the chamber temperature within 1 h, the temperature fluctuation can be effectively reduced by 30 %. One piece of phase change materials package was set up in the head, arm and leg, respectively. And four Phase change materials packages were set up in the chest and back, respectively. The test results showed that the internal temperature of the Phase change medical protective clothing could be sustained reduction of 8 %. The internal relative humidity increased by about 21 % compared with the normal medical protective clothing. The thermal comfort of the MPC was improved by 62.55 %, 26.43 % and 6.37 % for the head, back and chest, respectively. The remaining parts should be considered for future work.
