Details introduction
Equipment Overview
DLZL-DR05 Domestic Refrigerator Trainer vocational training equipment is made from an actual large domestic refrigerator-freezer, the Basic Refrigeration Learning System is ideal for exploring the typical operational and functional properties of HVAC systems. Principles of operation can be demonstrated as well as basic operational drills performed. Original cabinets are provided, many key components have been relocated and placed next to the equipment for visualization.
The refrigeration learning system functions same as domestic refrigerator/freezer of about 100-200 liters, with a freezer, freezer section. Part of the interior is fitted with a glass panel. Sight glass and high/low pressure gauges are installed in front of the evaporator, which is more convenient for continuous observation of the refrigerant state. The operation of the unit is controlled by a thermostat, and it is possible to monitor the temperature of the refrigerant at various states along the refrigerant line through a multi-point digital thermometer. Temperature readings and pressure readings are used to plot a pressure-enthalpy (P-H) diagram of the refrigerant cycle so that the thermodynamic properties of the refrigerant can be observed.
Equipment Features
-The workbench includes a demo board with the components mounted.
-The refrigeration circuit is shown on a color printed diagram.
-The control panel with instruments includes main switch and leakage circuit protection device, pneumatic key switch, emergency stop button, overload protection device, operation indicating device, also has 6 electrical faults and 1 mechanical fault, voltmeter, ammeter and temperature Display panel gauges serve as the standard for control trainers and ease of measurement.
-Dashboard: circuit breaker and earth leakage protection device, voltmeter, ammeter, indicator light, key selector switch, digital temperature gauge, 10 electrical fault insertion systems and 1 mechanical fault system, 20 electrical measuring points with test points
-Electrical diagrams, clear and color- coded system diagrams and connection schematics.
-The product is set up with four thermocouples capable of measuring the temperature at four different points.
-The RS485 information acquisition system can realize the refrigeration system built by the computer and itself, and transmit the data to the computer through the RS485 information acquisition serial port. The transmitted data includes voltage, current, phase angle, frequency, power, high voltage and low voltage, time and other values.
-Schematic diagram of the refrigeration training equipment, which can be printed through the computer.
