These differ in their characteristics decisively from flow equipment which include the turbo compressors that are common in very large systems. In Piston Compressors the flow rate is mainly dependent on the displaced volume and speed. Smaller refrigeration systems usually have a Piston Compressor. Because the flow rate is a measure for the refrigeration capacity of the refrigeration system, the properties of the compressor are important for the capacity of the whole system. Piston compressors are positive displacement machines. Due to the unavoidable dead space the flow rate drops with increasing pressure ratio.

With this board the students can study the operating principle of the transmission of digital signals using the most common modulations such as ASK(Amplitude shift keying), FSK(Frequency shift keying) and PSK(Phase shift keying) with the aid of encoders decoders NRZ, RZ, Manchester, Bi phase and Duo binary. The design and construction of electronic circuits to solve practical problems is an essential technique in the fields of electronic engineering and computer engineering.
Circuit Blocks:
Bi phase coding and decoding
NRZ (Non Return to Zero) coding and decoding
Duo binary coding and decoding
RZ (Return to Zero) coding and decoding
PSK modulation and demodulation
ASK modulation and demodulation
FSK modulation and demodulation.
The heat generated can be dissipated via cooling water connections, enabling continuous operation. The heat transferred can be calculated. Connections for an external heating circuit are provided on the rear of the boiler. An integrated hot water circuit with plate heat exchanger simulates the heating circuit in a house. This allows them to be expanded into a complete heating system using training panels. Different operating points can be investigated by changing the oil pressure after the preset boiler water temperature has been reached.

The worm gear wheel and worm are ball bearing-mounted. The forces are generated by the sets of weights and can be quickly and easily varied.
The transmission ratio of the gear can be determined. Permits investigations of the torques and the efficiency of the gear unit. Students learn the basic terminology of gearing in a simple manner: numbers of teeth; modulus; reference circle and axle base.
The well-structured instructional material outlines the technological fundamentals and provides a step-by-step guide through the experiments. The model is intended for wall mounting.
The unit is supplied with a number of interchangeable test sections to give a wider knowledge and understanding to the students. The Computer Controlled Air Duct Systems Unit examine how the air can be distributed in a building. The student can plan, design and construct different air duct systems with several components such as pipes, bends, branches, reducers, filters, valves, etc.

Proton Exchange Membrane Fuel Cell incorporates a unique membrane electrode assembly for the stack cells, each of which is internally reinforced and water cooled. The Proton Exchange Membrane fuel cell is one of the current leading contenders as a power source for use in motor vehicles. The fuel cell generates electrical power directly from hydrogen and air producing only pure water and heat as a by-product.
This gives the cell a high watt density and allows students to investigate a practical fuel cell with a realistic output capable of driving significant electrical loads up to 0.75kW. Unlike other educational units on the market the Proton Exchange Membrane Fuel Cell utilises an award winning module that is identical to those used in an actual vehicle power supply currently in production.
