مبدأ العمل
Refrigeration: Tecumseh hermetic compressor(France) with R404A refrigerant; SWEP plate heat exchanger; finned condenser with fan motor; multi-stage finned evaporator with auto-load capacity adjustment. Capacity-controlled expansion valve modulates refrigerant flow to match heat load. PID-controlled heating, humidification/dehumidification with PT100 dry/wet bulb sensors. Same-temperature-layer design prevents top-of-chamber condensation; double-seal door with triple-vacuum glass viewing windows.
