Development and experimental study of a miniature vapor compression refrigeration equipment

摘要

A miniature vapor compression refrigeration equipment prototype was developed for a range of microclimate control applications,including man portable cooling and distributed space conditioning.The miniature refrigeration equipment has dimensions of 260 mm x 250 mm x 120 mm,and weighs approximately 2.85 kg.The optimal motor and its transmission ratio,the optimal dimension of capillary tube and the optimal quantity of refrigerant charge were obtained by matching and operating performance experimental study.Experimental results show that the miniature refrigeration equipment can provide 300 W cooling,and its COPc is above 2.0.
