  Domestic Refrigeration Trainer PC

  The system demonstrates the operation of a compression refrigeration unit. A closed, insulated chamber is cooled using a refrigeration circuit comprising a compressor, condenser, evaporator and capillary tube. A special feature is the ability to enlarge the heat exchange area of the condenser by switching in a 2nd stage. It is possible to use the unit to simulate faults.The intake and delivery pressure of the compressor are indicated on pressure gauges with an additional temperature scale for the refrigerant and recorded using pressure transducers. Temperature sensors measure the relevant temperatures. Their values are indicated on a digital display with selector switch. A further switchable display indicates the voltage, current and power consumption of the compressor. At the same time, the measured data can be displayed and processed on a PC. A data acquisition card with appropriate software is included.

  Domestic Air Conditioning Controls

  The unit facilitates the investigation of electrical components used in air conditioning. This includes fault simulation and faultfinding on a compressor and fan motor. These devices are simulated with this unit. During this process the switch state of the equipment is indicated by signal lamps that are arranged on the display and control panel. The related starting, safety and control devices are also clearly laid on the front panel. Laboratory sockets facilitate access to measured points in the electrical circuit. The simulation of 15 faults that can be enabled via the electrical system is performed using push buttons. The series was designed primarily for training on refrigeration and air conditioning systems and is particularly suitable for use in small student groups.

  Refrigerant Compressor Fault Simulator

  The table unit is part of a series designed for training in refrigeration engineering. The unit addresses electrical faults as they can occur in the operation of a commonly available refrigerant compressor. The faults are simulated using pushbuttons on the front panel of the unit. Other components as, a switch box with the starting relay, running capacitor, starting capacitor and motor protection circuit breaker are also arranged on the front panel. The measured points in the electrical circuit are accessed using laboratory sockets. A circuit diagram printed on the front panel provides information on the circuit.

  Gas Heated Absorption Refrigeration Unit

  Unlike mechanically driven compression refrigeration systems, absorption systems use thermal energy directly. There are three circuits in the system a water circuit, an ammonia circuit and a hydrogen circuit. The system comprises a generator, a condenser, an evaporator with a downstream gas heat exchanger, an absorber and a liquid heat exchanger. The generator is heated with gas not electricity. The unit can therefore be operated independent of the mains electricity.
