The hermetically sealed refrigerant compressor incorporates a brushless three phase DC electric motor that is driven by a variable speed controller. Compressor speed and power supplied is displayed on the PC.
The condenser and evaporator are brazed plate heat exchanger and utilize a large common reservoir of water to minimize changes in water temperature during operation. The refrigerant exiting the compressor passes through a condenser, receiver, filter, variable area flow meter, expansion valve and evaporator before retuning to the inlet side of the compressor.

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. This training 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. All components of the trainingsystem have ball valves at the connections. Using the required accessory kit thecomponents are connected into a complete refrigeration system. The base unit Refrigeration Training 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. The refrigerant R513A serves as working medium. A pressure switch protects the compressor against excessivepressure. For the completeexperimental setup laboratory workplace with frame for mounting the componentsand power supply, is required.

Refrigerator Unit Model consists of arefrigeration chamber with a heater as cooling load, evaporator, fan andvarious expansion elements. The fan supports the achievement of an eventemperature distribution in the chamber. Refrigerator Unit Model is part of the HSI trainingsystem for refrigeration and air conditioning technology. In combination withthe base unit HSI training system refrigeration and air conditioningtechnology, base unit the operational model of a domestic refrigerator iscreated. Solenoid valves enable the operation of the systemwith capillary tube or with expansion valve. All components are clearlyarranged on a panel. The model is plugged onto the base unit, secured using fasteners andconnected with refrigerant hoses to become a complete refrigeration circuit. The softwareoffers the option to simulate faults. Temperaturesand pressures in the system are recorded by sensors and displayed dynamicallyin the software. A cooling load can additionally besimulated with the heater. The operation of individual system components, here the temperature control, fan, heater, compressor and solenoid valves, takes place via the software. The effect of parameter changes can be tracked online in thelog p-h diagram.

The solar energy is captured by a cylindrical parabolic solar concentrator in which the parabola axis is constituted by a high thermal conductivity tube and black colour containing an adequate liquid able to capture the solar energy increasing its temperature. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle is one of the most interesting applications of solar thermal energy because it is able to use the solar energy and, via an absorption cycle, to convert the energy in a source of cold that can be used for food conservation chain, air conditioning, chilling water and in general in all the applications of refrigeration and conditioning purposes without the use of electrical energy. The Computerized Educational Equipment On The Thermal Solar Refrigeration Cycle has been designed and manufactured by Italia to allow the experimental study of an absorption refrigeration plant using solar energy as energy source. Owing the peculiarity of the plant able to use the solar energy to convert it in a source of cold, the plant is particularly interesting in all the countries of the equatorial area, where the sun is the main energy source and the coverage of the electrical network is scarce.
