With the AG-328 unit we can examine and study a refrigeration circuit under an adjustable load. Refrigeration circuit with water circuit as load. Defined cooling load by controlled water temperature.The purpose of this refrigeration circuit is the production of cold water.This unit is mounted on an anodized aluminium structure and panels in painted steel.Main metallic elements in stainless steel.Diagram in the front panel with similar distribution to the elements in the real unit.Refrigeration circuit with:Compressor, computer controlled.Condenser with fan, computer controlled.Thermostatic expansion valve.Evaporator.Water circuit with:Pump, computer controlled.Tank with heater as cooling load at the evaporator.The heater is computer controlled to adjust the tank temperature.Pressure switches.Temperature sensors distributed at key points of the unit, to measure the coolanttemperature, the water temperature and the air temperature.Pressure sensors and Manometers.Coolant and water flow sensors.Power measurement from the computer (PC).This unit has been designed for the use with SES36 refrigerant, CFC-free.The complete unit includes as well:
Advanced Real-Time SCADA.Open Control + Multicontrol + Real-Time Control.Specialized EDIBON Control Software based on Labview.National Instruments Data Acquisition board (250 KS/s , kilo samples per second).Calibration exercises,which are included, teach the user how to calibrate a sensor and theimportance of checking the accuracy of the sensors before taking measurements.Projector and/or electronic whiteboard compatibility allows the unit to be explained and demonstrated to an entire class at one time.Capable of doing applied research, real industrial simulation, training courses, etc. Remote operation and control by the user and remote control for technical support, are
always included.Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic & Software).Designed and manufactured under several quality standards.Optional CAL software helps the user perform calculations and comprehend the results.This unit has been designed for future expansion and integration. A common expansion is the Scada-Net (ESN) System which enables multiple students to simultaneously operate many units in a network.
