SR261010SB04 Basic Refrigeration Trainer Educational School Laboratory Workbench Vocational Education Equipment Refrigeration Trainer
Purpose: Fundamental refrigeration cycle trainer permitting direct observation of the refrigerant phase
change.
Compressor: Not less than 1/2 HP,220 V / 1 phase / 50 Hz,reciprocating. Refrigerant R-134a. R-22 and
anyotherHCFC.
Condenser: Air-cooled.Thecondensing process observable by thetrainee,by a transparent
pipe or vessel section, a glass-bodied heat exchanger, a sight window or a sight glass in the condenser
outletline. Themeans ofobservation declared.Thefanmotorrating declared.
Evaporator:Air-cooled. Theevaporatingprocessobservable by the trainee,by the samerange
ofmeans as the condenser. The means ofobservation declared.Thefan motor rating declared.
Transparent Piping: Transparent pipe holder for observing refrigerant phase change at both condenser
and evaporator
Receiver&Separator:bothtransparentor fittedwithasightglass,rated for theoperatingpressureand
provided with a burst shield.
ExpansionValve:3/8"nut-fastening typeorwelded;adjustable
Graphic Module: Agraphic or mimic panel and a control panel, of anodised aluminium or powder-coated
steel. The graphic panel shall cary a complete schematic of the refrigeration circuit with every
componentidentified,legible at aviewingdistanceof2metres,and the physical components
mountedon or adjacent totheir schematic positions. Panel dimensions declared.
Digital Thermometers:Temperature indicatedatnot less than 6points,by panel-mounteddigital
indicator-controllers,by amulti-channel digital indicator,by the host software,or by any combination of
these.Not less than2ofthepointscontrollable set-points.
Control Panel: NFB 15A;magnetic switch; thermal relay; watt meter; timers;lamps (R/G/Y/W)
Data Board/ Software: Measurement points shall cover, as a compressor suction and
discharge,condenser inlet and outlet,expansion device inlet and outlet,evaporator outlet and ambient.
The number,type and location ofsensors declared.Interface:wirednetworkor USBinterface to
a host PC.Software for Windows 10/11 with Mollier and pressure-enthalpy diagram auto-draw and data
logging.
