  Set of Training Panels Expansion

  Consists of 15 different training panels that can be mounted modularly on the basic unit. These panels enlarge the scope of experiments of realised with the basic unit, training panels included in and accessories in comprises more complex refrigerant components as capacity controller, suction pressure controller, defrost timer, four-way reversing valve and case controller. A four-way reversing valve is used to reverse the cycle. A frozen evaporator can be defrosted with a reversed cycle. The evaporator is then temporarily used as a condenser.

  Single Chamber Refrigerator Module

  The experimental set-up is clearly arranged on a metal board which is placed on the base unit. The pipe connection between base unit and auxiliary module is made via self-locking Schrader valves. The individual components of the unit, in this case temperature control, fans, heater, compressor and solenoid valves, are controlled by the software (included in the scope of supply of the base unit). The refrigerating capacity is generated by an evaporator in an enclosed chamber. A blower is used to help achieve the even distribution of temperatures in the chamber. In addition, a heater can be used to simulate a cooling load. Solenoid valves permit the operation of the unit with a capillary tube or with an expansion valve as the expansion element.

  Refrigeration Technology Demonstration Panel

  The system is designed for the demonstration of the cyclic process on the p-h state diagram. The experimental set-up is clearly arranged on a metal panel with a system schematic. The use of commercially available components such as a finned pipe condenser and coaxial evaporator ensure a high degree of relevance to practice. A cooling load can be applied to the evaporator using water connections. Instruments enable the processes in a cooling system to be investigated and the energy transfers balanced.
