Construction and Design
The Split AC System Trainer PolarX-552 is built around a real commercial 18000 BTU (1.5 ton) split system air conditioner mounted on a dividing wall. The inner unit, housing the evaporator with variable fan speed, is mounted on the front panel. The outer unit, housing the forced air condenser, hermetic compressor, capillary tube expansion element, and heating/cooling reversing valve, is mounted on the back panel. This construction replicates the split principle as installed in a real building, with both units fully accessible for inspection and instrumentation. Two refrigerant manometers display suction side pressure (-1 to 16 bar) and delivery side pressure (-1 to 25 bar). Six Type-K temperature sensors across the circuit provide digital temperature monitoring over a -40 to 400°C range. A pressure safety switch on both suction and delivery sides protects the compressor. A 1.2 L liquid receiver and filter drier, both rated to 450 psig, are integrated into the high-pressure side of the refrigerant circuit. A digital multifunctional power meter measures AC voltage and current for power consumption analysis. Remote control operation selects operating mode, fan speed stage, desired room temperature, swing grill position, sleep timer, and the 24-hour on/off timer. This split AC system trainer interfaces with optional Software PX-552 developed in National Instruments LabVIEW for DAQ-based measurement and results calculation on any Windows operating system, with electronic sensors included when the software option is selected.

Frequently Asked Questions
Q1: How many operating modes does the Split AC System Trainer PolarX-552 support?
Six operating modes are supported: cooling, heating, dehumidifying, ventilation, automatic, and test. Three additional functions are configurable via remote control: sleep, swing, and a 24-hour timer.
Q2: How does the dividing wall construction of this split AC system trainer work?
The dividing wall mounts the inner unit (evaporator with variable fan speed) on the front panel and the outer unit (forced air condenser, hermetic compressor, expansion element, and reversing valve) on the back panel, replicating the physical separation of a real split AC installation while keeping both units fully accessible.
Q3: What is the cooling and heating capacity of the PolarX-552?
Cooling capacity is approximately 3.3 kW and heating capacity is approximately 3.4 kW. The unit is rated at 18000 BTU (1.5 tons) with a power consumption of approximately 1.7 kW in cooling mode.
Q4: Can refrigerant leak detection be performed with the PolarX-552?
Yes. Leak detection is covered as part of the experiment programme. An optional refrigerant leakage detector (PolarX-552-01) is available as an accessory.
Q5: Is data acquisition software available for the PolarX-552?
Yes. Optional Software PX-552, developed in National Instruments LabVIEW, provides digital data acquisition, measurement, and results calculation. Electronic sensors are included when this option is selected, and the software runs on any Windows operating system.
