Refrigerator Model | PolarX – 588
The Refrigerator Model PolarX – 588 forms a functional domestic refrigerator model when plugged onto the base unit PolarX – 588, part of the HSI training system. This Refrigerator Model features a transparent refrigeration chamber (265x265x265mm) with a 150W electric PTC heater as cooling load, a thermostatic expansion valve, and a capillary tube (1.6~2.2m) selectable via solenoid valves. Sensors monitor temperature (3x, -100~400°C) and pressure (-1~15bar), with optional software enabling fault simulation and p-h diagram tracking.
The Refrigerator Model PolarX – 588 is part of the Hardware/Software Integration (HSI) training system for refrigeration and air conditioning technology. When used with the base unit PolarX – 588, this Refrigerator Model forms a functional model of a domestic refrigerator.
Product Overview The module attaches securely to the base unit with fasteners and connects to refrigerant hoses to create a complete refrigeration circuit. The trainer includes a refrigeration chamber equipped with a heater for simulating cooling loads, an evaporator, a fan, and various expansion elements. The fan ensures even temperature distribution within the chamber, while the heater simulates additional cooling loads. Solenoid valves allow the system to operate either with a capillary tube or an expansion valve. All components are neatly organized on a panel.
System components such as temperature control, fan, heater, compressor, and solenoid valves are managed through the software, which is optional. The software also offers fault simulation capabilities. Sensors monitor and record temperatures and pressures, which are displayed dynamically in the software. Changes in parameters can be tracked online using the p-h diagram.

Construction and Design
The Refrigerator Model PolarX – 588 attaches securely to the base unit using fasteners and connects via refrigerant hoses to complete the refrigeration circuit. The refrigeration chamber measures 265x265x265mm and features a transparent front. An electric PTC heater rated at 150W generates the cooling load, while a fan ensures even air circulation within the chamber. Solenoid valves allow selection between a thermostatic expansion valve and a capillary tube (length 1.6~2.2m). All components are neatly organized on a panel for clear visibility.
