Description

The TCP300 bench allows the study of a refrigeration cycle.

The bench is made of standard elements of a refrigeration circuit. The compressor will first elevate the pressure and the gas temperature (R134a). The condenser will then transform this high pressure gas in the high pressure liquid. The high-pressure liquid will then be stored in a bottle and then be sent towards the expansion valve. This will change the state of the fluid, it will go from a high pressure liquid to a low pressure liquid. This low pressure liquid is now in the evaporator and will draw its energy on the coil (and thus cool it). The fluid is in the form of low pressure vapor, it goes through a suction line accumulator and be compressed again by the compressor. The bench comprises two exchangers, an air exchanger and a water exchanger. The air exchanger is similar to those found on conventional industrial installations.

The water exchanger is an exchanger didactic; students visualize the transformation because the refrigerant condenses between the glass shell and the cooling coil.

The machine cycle is reversible, Each exchanger can be used either as condenser or evaporator. The reverse cycle valve is similar to that found on conventional installations, particularly in the reversible air conditioning.

The bench is autonomous and requires a power supply 230VAC single phase + neutral. The module is set up on a frame made of screwed anodized aluminum profile (dimensions 45x45mm) equipped with directional castors with brake (diameter 100mm).

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

Its anodized aluminum profile frame on multidirectional wheels with brakes makes it extremely robust as well as 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 with 4 wheels. It includes an electrical cabinet with main switch and differential circuit breaker.
