Refrigeration components for advanced experiments
|Name:||Refrigeration components for advanced experiments|
ET 910.11 enables in conjunction with ET 910, ET 910.10, ET 910.05 and the accessory set ET 910.12 the performance of advanced experiments related to refrigeration.
Commercial components are used in practical experiments. These components are mounted on plates ready to be connected and are arranged clearly in the frame of ET 910.05.
The set includes complex refrigeration components, such as capacity controller, intake pressure controller, defrost timer, four-way reversing valve and refrigeration controller. The four-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 interlaboratory thermometers.
