DLZL-DR05 Domestic Refrigerator Trainer

A domestic refrigerator trainer is a specialized educational apparatus designed to provide hands-on learning experiences for students, technicians, and professionals in the field of refrigeration and appliance repair. This trainer simulates the operation and components of a typical domestic refrigerator, allowing users to gain practical knowledge of its construction, operation, maintenance, and troubleshooting.

At the core of the domestic refrigerator trainer is a scaled-down replica of a household refrigerator, complete with key components such as the compressor, condenser, evaporator, expansion valve, and refrigerant lines. These components are arranged and labeled for easy identification, enabling users to understand the refrigeration cycle and the role of each component in the cooling process.

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, and many key components have been relocated and placed next to the equipment for visualization.

The refrigeration learning system functions same a 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.

Dolang domestic refrigerator trainer serves as a valuable educational tool for individuals looking to gain practical skills in refrigeration technology and appliance repair. By providing hands-on learning experiences in a controlled environment, these trainers help users develop the knowledge and confidence needed to succeed in the field of domestic refrigeration maintenance and servicing.

Technical Parameters:

Model: DLZL-DR05 Domestic Refrigerator Trainer

-Power supply: single-phase 220V±10%, 50Hz, 16A;

-Test bench size (mm): 1065 (length) × 900 (width) × 1800 (height);

-Test bench body: movable steel bench body with four casters (two with brakes and two without brakes).

Key Features:

One of the primary functions of a domestic refrigerator trainer is to provide a platform for hands-on experimentation and demonstration of refrigeration principles. Users can manipulate system parameters such as temperature settings, compressor speed, and airflow direction to observe how changes affect the refrigerator’s performance, cooling capacity, and energy consumption.

Furthermore, domestic refrigerator trainers often incorporate instrumentation and sensors to measure critical parameters such as temperature, pressure, and electrical currents. This real-time feedback allows users to monitor system operation and diagnose any abnormalities or inefficiencies that may arise during testing.

In addition to operational training, domestic refrigerator trainers typically include modules on maintenance and troubleshooting. Users can practice routine maintenance tasks such as cleaning condenser coils, checking refrigerant levels, and replacing worn-out components. Moreover, troubleshooting modules simulate common faults and malfunctions, allowing users to diagnose problems such as compressor failures, refrigerant leaks, and defrost system issues.
