Description

The bench CRD100 allows the study of the refrigeration cycle. The circuit contains the most common components of a refrigeration installation (compressor, condenser, expansion valve, evaporator and accessories). The condenser and the evaporator are water exchanger.

The students should first start the compressor and then adjust the flow of water in the exchanger.

When the cycle is stabilized, the students can collect manually the data (pressure, temperature).

The teacher can request that the student change the flow of water to show the effect on the efficiency of the cycle.

The robust design of this device makes it suitable for use in schools.
The equipment is set up on an Anodized aluminium frame on feet. This gives it great strength and a flexibility of integration into your premises.
The manufacture of this equipment complies with the European standard for machinery manufacturing

The trainer is installed on a structure in screwed aluminum profile equipped with 4 feet with non-slip pad.
