Description

The TCP200 bench has been designed tostudy of refrigerating cycle.

The bench is made of standard elements of a refrigerating circuit. The compressor will first elevate the pressure and the temperature of the vapor (R134a). The air condenser will then transform this high pressure vapor  into high pressure liquid.

The high pressure liquid will then be stored in a receiver and then be sent towards the expansion valve. This one will change the state of the fluid, it will change from a high pressure liquid to a low pressure mix (liquid+vapour). This low pressure mix is now in the evaporator and will draw its energy on the water coil (and thus cooling it). The students visualize the transformation because the refrigerant evaporates between the glass shell and the cooling coil. At the outlet of the evaporator, the fluid is in the form of low pressure vapor, it goes through a suction accumulator and will be compressed once again by the compressor.

The robust design of this equipment makes it perfectly suited for use in schools.

Its anodized aluminum structure on wheels makes it extremely robust as well as a great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive

This unit is set up on a frame made of aluminum profile. It includes an electrical cabinet with main switch and a GFCI.
