Experimental Study on a New Type of Shipping Container Refrigeration Unit

Abstract

In this paper the technical features of various representative shipping container refrigeration units were reviewed firstly. A new type of shipping container refrigeration unit was developed. The pull-down experiment was carried out in cool mode (setpoint 0°C) and frozen mode (setpoint-18°C) using the test rig for the refrigeration unit. The experiment results shown that the new type of shipping container refrigeration unit had good pull-down performance respectively in cool mode and in frozen mode. Meanwhile, the control accuracy of the temperature of air inside container can reach ±0.3°C successfully.
