ET 410

Refrigeration Technology Demonstration Panel

Technical Description

The system is designed for the demonstration of the cyclic process on the p-h state diagram. The experimental set-up is clearly arranged on a metal panel with a system schematic. The use of commercially available components such as a finned pipe condenser and coaxial evaporator ensure a high degree of relevance to practice. A cooling load can be applied to the evaporator using water connections. Instruments enable the processes in a cooling system to be investigated and the energy transfers balanced.
A supply of water is required.
The panel can be mounted on the HL 100 Universal Stand.
