Abstract

PURPOSE: To deal with the change of cooling load by selectively using the multi number of expansion valves, which are connected in parallel and which are connected with the electromagnetic valve in series, in accordance with the conditions of the load.
CONSTITUTION: Multi number of circuits of the reducing devices 4,7,9 and the electromagnetic valves 3,6,9 which are connected in series are arranged in parallel to open or cloe the electromagnetic valves 3,6,9 in accordance with the condition of the load to use reducing devices 4,7,9 selectively. By doing so, increase or decrease of the cooling load can be taken care of by sensing the temperature and the pressure changes according to the condition of the load and selectively using each device.
