【正文】 2 The energyconservation of freezer, with automaticallying control 1 A present freezer of automatic control current situations Though the cold storage selfcontrol having been popularized all round, but great majority cold storages putting particular emphasis on is only a safeguard face to face , the energy conservation having increased Wenku picking up the selfadjustment and cold storage measuring and controlling, to entire system relates that under the control of seldom or. Even if another aspect, already getting the allround universal safeguard, before actual condition in working can39。t admit of no sanguine, } pins up the cold storage selfcontrol facilities having bee ear of the deaf person even having bee furnishing and decorating decorating front appearance only. The Shanghai cold storage association has done investigation in recent years to Shanghai area ammonia refrigerating system cold storage safeguard and autocontrol condition , concrete conditions has seen that are what form l shows. A spot of should inquire into a data as the leopard has reflected current cold storage selfcontrol general situation Form what 1 shows a selfcontrol interposes and runs status though the very good cold storage only having 5 tidal current and direction accounting for 9% of the number counting, but it is these cold storages to have represented a nowadays. With the development of electron technology, the selfcontrol ponent is more and more advanced , changeable procedure controller (PLC) and the PC function are more and more strong , selfcontrol procedure is more and more perfect, system optimization and the energy conservation consciousness are also more and more strong. The cold storage energy conservation and the autocontrol relation are more and more rapid and intense , need the cold storage energy conservation to be ready for and posing much better, do well in and be engaged in better the autocontrol vitally needing right away. Abovementioned example adopted by five cold storages representing tidal current in the nowadays and advanced level has all got the pretty important effect to realizing cold storage energy conservation. 2 How be ready for cold storage energy conservation autocontrol Fundamental abovementioned content starting point is the cold storage taking ammonia as all together style refrigeration working medium refrigerating system , is that refrigeration working medium decentralization, allows all together style , all together style refrigerating system cold storage to have got very big development , whose selfcontrol degree overtops also sometimes the all together style refrigerating system cold storage taking ammonia as refrigeration working medium on behalf of a hydrocarbon with the thick gravy nowadays. Many working mediums are unlike cold storage of system of all kinds extensive use, content having enriched cold storage autocontrol tremendously, application in energy conservation at the same time also has provided the vast scope for one39。s ability to autocontrol in the cold storage. Cold storage energy conservation autocontrol Cold storage energy conservation autocontrol is energy conservation under the control of procedure establishment and selfcontrol ponent selecting and using from the content ing to study the autocontrol developing cold storage energy conservation39。s relates that mainly whom. The firm, special field designing institute or capable unit as selfcontrol ponent may assume cold storage energy conservation autocontrol research and develop equally. The firm and the designing institute make a contribution to some extent without exception already by now within that field. Cold storage energy conservation autocontrol can be developed exploitation monly by firm and designing institute best (not bad firm give first place to, the designing institute coordin
