Fonctionnement

Refrigeration system uses Tecumseh compressor with SWEP plate heat exchanger and R404A refrigerant; finned condenser (with fan motor) and finned multi-stage evaporator with auto-load capacity adjustment. Auto refrigerant flow modulation matches heat load. PID-controlled heating, humidification and dehumidification with PT100 dry/wet bulb sensors. Same-temperature-layer structure prevents top-of-chamber condensation; double-seal insulated door, polyurethane plus glass-wool insulation 100 mm thick.
