KTE-1000BA
STANDARD REFRIGERATION EQUIPMENT

Equipment Introduction
Composition of Compressor, Condenser (with fan motor), Receiver, Filter-dryer, Sight glass, Solenoid Valve, Manual Expansion Valve, Evaporator (with fan motor), High, Low pressure gauge
These devices run as set up circuit in control panel
The DAQ program supplies tools which measure temperature, pressure, enthalpy and the amount of exchanged heat in each position in real time, and then saves the data in an Excel file, so that data can be shown and analyzed in graphical form
Equipment Characteristics
System Cycle Configuration
Compressor → Condenser → Filter Dryer → Sight Glass → Expansion Valve → Evaporator → Compressor
Operation Modes
The system can be operated in manual control, temperature control, or pump-down modes, using either sequence control circuits or a PLC-based control system.
Performance Measurement & Monitoring
The system provides automatic measurement of refrigeration performance, data acquisition, and real-time system monitoring through dedicated software.
Temperature Measurement
Temperature can be measured using K-type thermocouples at the following points:
Compressor inlet and outlet
Condenser inlet and outlet
Expansion valve inlet and outlet
Evaporator outlet
Inside chamber
Ambient (outside air)
Pressure Measurement
Pressure can be measured within a range of –1 to 35 bar using installed pressure sensors at:
Compressor inlet and outlet
Condenser outlet
Expansion valve inlet
Experimental Parameters
Refrigeration effect
Compressor work
Condensing effect
Evaporating latent heat
Amount of flash gas at expansion valve outlet
Dryness fraction and humidity at expansion valve outlet
Coefficient of Performance (COP)
Measured temperature and pressure data
Data Storage
Measured data can be recorded at one-minute intervals, and saved as an Excel file for up to 1,440 minutes by clicking the “SAVE” button.
