ZM7157 Vapor-Compression Refrigeration Unit Teaching Equipment Refrigerator Training 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.
