TRAB — Absorption Refrigeration Unit

Brand: EDIBON | Category: Scientific & Laboratory

The EDIBON TRAB Absorption Refrigeration Unit is a didactic bench designed to demonstrate the absorption refrigeration cycle using an ammonia-water working pair. Unlike vapour-compression systems, absorption refrigeration uses heat (rather than mechanical work) as the primary energy input, making it ideal for waste-heat recovery and solar-driven cooling applications. The unit allows students to measure COP, analyse the thermodynamic cycle on a P-h diagram, and study the roles of the absorber, generator, condenser, evaporator and heat exchanger.
