## Description Générale

The Simple Compression Refrigeration Circuit Unit "TSCR" represents the typical compression refrigeration system with compressor.

The evaporator and the condenser have been designed as a copper pipe coil immersed in a water-filled tank, which simulates the environment.

There is a thermostatic expansion valve working as expansion element and the aggregate state of the refrigerant can be visualized through a sight glass located before the expansion valve.

To make energy balances and calculate the amount of heat removed in the evaporator by the cold water or the amount of heat discharged in the condenser by the hot water to the environment there are:

• Two thermometers that measure the water temperature in the tanks.
• Two manometers that indicate the system pressures in the high and low pressure sides. The evaporation temperature of the refrigerant is indicated in an additional scale in the manometer.

As safety element, the unit includes a pressure switch, which stops the compressor if pressure is high.
