About Refrigeration Components For Advanced Experiments

REFRIGERATION COMPONENTS FOR ADVANCED EXPERIMENTS

Commercial components are used in practical experiments. These components are mounted on plates ready to be connected and are arranged clearly in the frame.

The set includes complex refrigeration components, such as capacity controller, start-up controller, defrost timer, 4/2-way reversing valve and refrigeration controller. The 4/2-way reversing valve, for example, is used to reverse the circuit. This allows for the defrosting of an iced-up evaporator by operating it temporarily as condenser. Manometers provide an insight to the pressure ratios in the refrigeration circuit.

Via pressure and temperature measurements the changes of state of the refrigerant can be tracked and entered into the log p-h diagram. The temperature is measured by inter laboratory thermometers.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.

The unit shall perform the following experiments and investigations:
