泾渭分明读音Function
Refrigerating pha Liquid pass through shut-off valve PM 1 (1)kept open by its pilot EVM (2).
Liquid injection occurs through thermostatic expansion valve TE 20 (3). Main valve PM 3 (12) modulates the evaporating pressure in order to maintain the temperature
of the air being cooled.
The function is performed by CVQ pilot (14) which is itlf controlled by electronic regulator EKS
正弦定理余弦定理61 (15) with air nsor AKS 21 M (16). Pilot valve EVM (13) is open. Main valve PM 3 (6) in the high-pressure line is kept open by pilot E~ Defrosting valve PM 1(4) is
kept clod by pilot EVM (5).
Defrosting pha
郁闷什么意思Main valves PM 1 (1), PM 3 (6) and PM 3 (12) are clod -each by their own EVM pilot.
Main valve PM 1 (4) is opened by EVM pilot (5) and feeds hot gas against the direction of flow to the evaporators that need defrosting.
Setting
