Computer Controlled Capacity Control Methods in Refrigeration

Details

The Computer Controlled Capacity Control Methods in Refrigeration, "THARA2C/1", designed by EDIBON, allows to study and to investigate several methods of capacity control. For this purpose a refrigeration circuit with two refrigeration chambers is available in which a cooling load is generated using adjustable heating elements. Several fans in both refrigeration chambers ensure an even temperature distribution. The refrigeration capacity of the refrigeration can be adjusted via the computer controlled speed of the compressor. There also is the option to adjust the refrigeration capacity with the capacity controller situated in the compressor bypass. The unit includes a computer controlled air condenser, two evaporators in insulated refrigeration chambers, an accumulator, a filter, a flow sensor and a high and low pressure control. Each refrigeration chamber includes an computer controlled adjustable heating element, a thermostatic expansion valve, a sight glass and a computer controlled set of fans. In the first refrigeration chamber (refrigeration) a computer controlled solenoid valve and an evaporation pressure regulator control the flow and the pressure of the coolant in the e
