Cooling system of refrigeration top car using phase-change material and control method thereof

摘要

This invention relates to a cooling system of a refrigerator truck using phase change material. The invention comprises a ground cold storage delivering cooling power of a refrigerant cooled with AC refrigerator to PCM (Phase Change Material) through a heat exchanger of a ground cold storage tank; an on-board cold storage installed on the truck to deliver the cold in the ground cold storage to PCM through the heat exchanger of the on-board cold storage using brine circulation; and a cargo box cooling system that supplies the cold of the on-board cold storage to a heat exchanger in a cargo box through brine circulation to maintain a constant temperature inside the cargo box using forced convection.
