Refrigeration Training System Base Unit:
Thistraining system practical experiments relating to the operation of arefrigeration system can be implemented by dealing with differently configuredcompression refrigeration circuits. The components used are common inrefrigeration and therefore closely related to practice. The base unit RefrigerationTraining System includes the main components of a refrigeration circuit: acondensing unit with compressor, condenser and receiver and a refrigerationchamber with integrated evaporator, fan for forced ventilation and an electricdefrost heater. A pressure switch protects the compressor against excessivepressure. The refrigerant flow can be modified via shut-off valves. Togetherwith the components from heat exchanger, flow meter or manometer, simplerefrigeration circuits are realised. For continued experiments additionalrefrigeration components from advanced experiments are used post-injectionvalve, capacity controller or defrost timer. All components of the trainingsystem have ball valves at the connections. Using the required accessory kit thecomponents are connected into a complete refrigeration system. For the completeexperimental setup laboratory workplace with frame for mounting the componentsand power supply, is required. The refrigerant R513A serves as working medium.
