ZM7157A Vapor-Compression Refrigeration Unit Vocational Education Equipment For School Lab Condenser Trainer Equipment
Complete refrigeration system allowing demonstration of the vapor-compression refrigeration cycle
Fully instrumented to allow complete analysis of the processes involved and calculation of the changes in performance with operating conditions
Use of water as heat transfer medium in condenser and evaporator allows complete energy balance to be carried out and performance to be measured accurately
Computer controlled system with automatic recording of process variables using an integral USB interface device
Compressor driven by three phase motor with inverter drive giving variable speed and output torque measurement
Measurement sensors include:
9 x Thermistor sensors measuring temperatures throughout the system
2 x Electronic flow meters measuring flow of water through the condenser and evaporator
2 x Electronic sensors and 2x Bourdon type refrigerant gauges measuring pressures before and after the compressor
1 x Variable area flow meter measuring refrigerant flow rate
Supplied with large water reservoir to isolate the process from fluctuations in temperature or pressure in the mains water supply
Comprehensive instruction manual supplied.
