ZM6161 Split unit cooling heating system station training inverter laboratory equipment Refrigeration Trainer Equipment
I Introduction
This trainer is designed for the in-depth study of vapour-compression cycle. It enables to vary the load conditions of condenser and of evaporator, to use alternative devices for gas expansion, to handle successfully unexpected operating situations, such as the block of the refrigerant flow or a wrong gas charge inside the circuit. Students can become familiar with the refrigerant pressure-enthalpy diagram and evaluate the heat balances corresponding to the different cycle components, by using the set of industrial instruments of the equipment.
