The energy-conservation of freezer, with automaticallying control 1 A present freezer of automatic control current situations Though the cold storage self-control 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 self-adjustment and cold storage measuring and controlling, to entire system relates that under the control of seldom or. Even if another aspect, already getting the all-round universal safeguard, before actual condition in working cant admit of no sanguine, } pins up the cold storage self-control facilities having become ear of the deaf person even having become furnishing and decorating decorating front appearance only.

A spot of should inquire into a data as the leopard has reflected current cold storage self-control general situation Form what 1 shows a self-control 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 self-control component is more and more advanced , changeable procedure controller (PLC) and the PC function are more and more strong , self-control 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 composing much better, do well in and be engaged in better the autocontrol vitally needing right away. Above-mentioned example ado
