Reverse Cycle Refrigeration Training System- Engineering Lab Training Systems Description and Specifications for Lab Tenders
Reverse Cycle Refrigeration Training System- Engineering Lab Training Systems.
Technical Description
The contains a hermetic
compressor, 4 heat exchangers, 3 expansion valves and 4 different
interchangeable capillaries. The unit can be operated in different
modes. 11 manually operated valves allow corresponding changes to be
made to the refrigeration circuit. The relevant measured values are
displayed directly on indicator instruments. Therefore, sequences and
consequences of switching operations within a cooling unit can be
directly investigated. Sight glasses in the refrigerant circuit allow
direct observation of the refrigerant status. A coaxial tube bundle heat
exchanger can be operated as a counterflow condenser or as a parallel
flow evaporator. This heat exchanger is used to heat or cool a
glycol/water mixture circuit. Refrigerating loads are created by
different fan speeds on the finned tube evaporators.
