1.Overview
DLZL-WA02 Lab AC Circuit Trainer (Close Compressor Type) introduces students to the basics of air conditioning and refrigeration using a water cooled condenser system. Students will learn practical knowledge of the operation of vapor compression refrigeration cycles used in air conditioning and refrigeration systems. The water-cooled condenser discharges the heat of the refrigerant into the cooling water, and the refrigerant condenses into a high-pressure liquid. During operation, a pressure map (p-h) diagram of the thermodynamic cycle of a water-cooled condenser was investigated to fabricate a refrigeration system. A number of special control instruments and transparent viewports have been provided to set up and monitor various experiments.
