ET 900 enables familiarization with the operation and handling of a refrigeration system. The experimental unit includes all the necessary components for a fully operational refrigeration circuit, such as compressor, condenser, evaporator and a capillary tube as expansion element.
Fundamentals of a simple refrigeration circuit: detection and understanding of the cyclic process, changes of state of the refrigerant, representation the refrigeration circuit in the process schematic, representation of the cyclic process in the log p-h diagram, estimating key figures, refrigeration capacity and heat fluxes.
Different operating modes: air cooling, generating cold water, heat pump (generate hot water).
Practical exercises:draining and filling the refrigeration system (with ET 150.01), fault finding.
