The Oil Return In Refrigeration Systems is of key importance for the service life of the compressor and thus for a secure constant supply of refrigeration. In the vaporised refrigerant the oil remains liquid in the lower parts of the system. This can result in lack of oil in the compressor. To return the oil to the compressor, a minimum velocity must be maintained in the pipes. A small diameter of the rising pipe results in a high velocity and ensures the return of the oil even under partial load. However, at full load the pressure loss increases due to the small diameter. The velocity in the rising pipe depends on the pipe diameter and the refrigerant mass flow. In most compressors some lubrication oil is carried along with the compressed refrigerant. In the liquid refrigerant the oil is dissolved in the refrigerant and is transported without problems. If the velocity in the rising pipe on the intake side of the compressor is too low (partial load), the oil is not returned to the compressor due to its higher density.

Demonstrates the electrical circuit of a complex full conditioning system with heat pump function. The control circuits are actually present. The components in the load circuits are simulated (e.g. compressor, heater, 4-way reversing valve). Identifying electrical faults in air conditioning systems requires comprehensive knowledge. This knowledge includes the design and operation of the individual electrical components as well as the reading of circuit diagrams. Helps to acquire this knowledge. At very low outer temperatures an electrical auxiliary heating is activated during heating operation. With low air humidity the hygrostat activates the humidifying function. The air conditioning system with heat pump function cools in the summer and heats in the winter. During heating operation the defrost timer introduces a hot gas defrosting by briefly switching the 4-way reversing valve. The operating state of the simulated components is indicated via lamps in the circuit diagram on the front panel. Typical protection devices, such as circuit breaker and frost protection monitor, complete the electrical circuit.

It is suitable for technical andprofessional training at different levels. It consists of a trolley mounted structure with a hydraulic power supply unit and two panels, one for the basic oil power components and one for On/Off and proportional electrical control. The panels can be used independently, using an external hydraulic power supply with suitable characteristics. Modular Oil Power Hydraulic Trainer is a modular system specially designed to test out the techniques for the transfer of fluid power and electro hydraulic control techniques. The two panels are functionally independent, but can be coupled so as to form a double-faced structure, whichis installed onthe trolley mounted frame.
The trainer is supplied with anexhaustive manual, including a technical description of all the components, operating and maintenance instructions and many exercises. The Modular Oil Power Hydraulic Trainer can be easily interfaced with PLC or anotherprogrammable logic controller available to theuser in order to program complex operating cycles.

The heat extracted is transferred to the hot reservoir, together with heat generated by the electrical supply to the peltier device. This heat is removed by a water-cooled heat exchanger. The flow rates can be adjusted to provide a range of operating temperatures. By varying the electric power into the system, the behaviour of the system at different operating points and temperatures can be established. The thermo-electric Peltier device is positioned in a heat transfer path, between two copper blocks, extracts heat from one block (cold reservoir) and transfers it to the other block (hot reservoir). In order to measure the heat transfer rate, the cold reservoir is fitted with an electric heater.
Instrumentation is provided to measure the temperatures of the blocks, the electric power supplied to the Peltier device, the cooling water flow rate and the cooling water temperature rise.
The Peltier device can also be used to generate a small quantity of electric power when a temperature difference is applied. This effect can also be demonstrated. The heater power is measured , and so it is possible to establish a complete energy balance for the system.
The voltage is set by means of a variable auto transformer with rotary knob and the output is floating by means of an isolating transformer with subdivided secondary winding. Variable Three Phase Transformer suitable for fine Âstep adjustment of three phase voltages from zero to maximum value. Fitted with mains lamp and motor circuit breaker.
