method of work pair in freon refrigerating system , add the back pressure valve on time of high temperature warehouse air tube , add single check valve on time of low temperature warehouse air tube, be representative block of wood energy conservation method of work, do not respond to encourage but suitable abolish. 4 Unexpected turn of events evaporates temperature adjustment Some one work state lower if evaporate temperature can use storehouse hot load and refrigerating system refrigerating output be parameter be in progress adjustment, then now that can reach energy conservation purpose can make energy adjustment be more rational. The sort Er Yan , refrigerating system evaporation implement and refrigeration pression engine equipment can satisfy maximal load need basically all. Load falls off but the refrigerating output can not make corresponding adjustment in time if the cold room is hot, the refrigerating output and hot load being that the refrigerating system evaporation temperature will may act in responses reduces , uses a pression engine reach a new balance burning. The lessening evaporating the temperature has increased but the refrigerating output evaporating an implement conversely but , has faced the hot load that self own cuts down taking form surely frequently opening the consequence staying. Evaporate temperature 10 C per change, electric energy about 3 ~ 5% acting in responses adding or subtracting. Be energy conservation on making system burn in another ideal balance of } if raising the evaporation temperature in time,have avoided freely not having achieved not only, having decreased by the refrigeration pression engine39。 s frequently starts , is the energy conservation measure achieving two things at one stroke. Not changeable fundamental refrigerant rate of flow rate of flow evaporating an implement adjusts. Changeable rate Changeable rate of flow adjustment ammonia in the past refrigerating system。 Freon system evaporates the implement refrigerant rate of flow , great majority achieve simple proportion measures. The air cooler air mass flow great majority do not measure or speed and the electric fan platform number measure only when two. This two kinds parametric rate of flow adjustment all are cold the adjustment assigning the equipment refrigerating output and storehouse temperature direct relevance , one of the content being also that the cold storage energy conservation selfcontrol responds to in taking seriously with the storehouse. Fetch the warehouse taken height Sets up right under the control of accuracy and adds the storehouse temperature setting up the modity and different storage period controlling the different storehouse , different stock out of gauge having no equal to and their under the control of accuracy request. Set off from the energy conservation angle, the storehouse temperature ought to take height not choosing low , the mild highaccuracy controlling accuracy ought to fetch the warehouse taken height , insisted to run after face to face unnecessarily low low controls as long as not affecting the modity quality. To the cold room of many } storehouse temperature under the control of, except original storehouse temperature setting value, suitable add set up Kuwen transfinite controlling value. This pair of factors storehouse temperature adjusts deflect but premature bringing into service being able to achieve when refrigerating system needs bringing into service , incapable because of } pins up the storehouse temperature。 Can not make cold according to reality that time at intervals, refrigerating system stops working untimely Ding , fully utilizes now having energy K avoid equipment or systematic frequently open Ding. Set up avoiding meeting high o peration Interpose avoid meeting high o operation under the control of electric power short。
