Description
It enables in conjunction with the accessory set 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
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.
