Explanation/Annotation:Electronic. Means of automatic monitoring for the automation of àìèà÷íûõ or halon refrigerator machines (units) with screw-type compressor by the refrigeration capacity from 125 up to 400 kilowatts.
Detailed model description:Application area - refrigerating installations, applied to enterprises of food and process industries, as much as on ships of sea fleet.
The administration of refrigerator machine shall be effected by instruction input on
Short-circuit or breaking of circuit of compressor starters, oil pump,
EM AND elements of tons. D.
Duties on automation:
- launch, stop motion of refrigerator, engines on specified algorithm;
- protection on reaching of limiting values controlled parameters
With number indication of parameter;
- indication running values of controlled parameter - coolant temperatures , portions of slide valve of compressor;
- automatic regulation of compressor output on is proportional to - integral or three-position law from åñThis is only test. Phleboid signal (coolant temperatures of refrigerating chamber) or from unitized input signal;
- stop motion of refrigerator machine upon the achievement preassigned value of controlled parameter in case of minimal compressor output followed by all-automatic launch;
- level control of coolant in evaporator on portion of slide valve.
Is composed of ýëåêòðîííî-ðåëåéíîãî block of ÝÐÁ-ÊÑÀ-01 and pressure sensors
