Design improvement on temperature and humidity control of medical refrigerator
A medical refrigerator with double doors and a volume of 1099 L,which only controls the temperature inside the refrigerator,is taken as the research object. Through reasonably matching the variable frequency compressor and the adjustable speed evaporator fan,as well as adding the regular hot gas defrosting,the transformation and test verification on the refrigerator are conducted.The results show that when the improved refrigerator operates stably not including defrosting period,the temperature in the box can be stabilized at 4.0-5.5 ℃,and the relative humidity can be stabilized at 45％-55％.
