DLZL-DR05 Skills Training Equipment Refrigerator Trainer of vocational education equipment 

Equipment Overview

(1) The DLZL-DR05 Skills Training Equipment Refrigerator Trainer of vocational education equipment is constructed of a movable aluminum profile and sheet metal workbench, which contains a demonstration board for mounting components. These components are neatly arranged in a manner similar to a refrigeration circuit for easy understanding. The refrigeration circuit is shown on the color print. The refrigeration pipeline uses red and blue color coding to indicate the state of the refrigerant. The control panel with instrument includes master switch and leakage circuit protection device, pneumatic key switch, emergency stop button, overload protection device, operation indicator device, 6 electrical faults and 1 mechanical fault, voltmeter, ammeter and temperature The display panel instrument serves as a standard for control trainers and easy measurement. The unit comes with a laboratory manual as a guide for practical exercises.

(2) Instrument panel: circuit breaker and leakage protection device, voltmeter, ammeter, indicator light, key selector switch, digital thermometer, 10 electrical fault insertion systems and 1 mechanical fault system, 20 electrical measurement points Electrical diagrams with test points, clear and color-coded system diagrams and connection diagrams.

(3) The product is equipped with four thermocouples, which can measure the temperature at four different points.

(4) RS485 information acquisition system: After the system is assembled, the computer and its own refrigeration system can be realized, and the data is transmitted to the computer through the RS485 information acquisition serial port. The transmitted data includes voltage, current, phase angle, frequency, and power , High pressure and low pressure, time and other values. It also includes the system schematic diagram, which can be printed on the computer terminal. It is used as HVAC majors training equipment widely.
