Using when above-mentioned joint operating device of the present invention, according to different instructions for uses, by adjusting the position of mobile thermal-insulation baffle plate and the duty of all Electric air valve, as follows to realize the different operational modes of joint operating device:
The first pattern, it is freezing and refrigeration pattern, the first compressor bank and the first air-cooled evaporimeter are realized heat exchange, the second compressor bank and the second air-cooled evaporimeter are realized heat exchange, the first air-cooled evaporimeter is separately for freezer provides heat exchange, and the second air-cooled evaporimeter is separately for refrigerator provides heat exchange.
As shown in Figure 2: the first Electric air valve 5, the second Electric air valve 6 are in closed condition, the 3rd Electric air valve 7, the 4th Electric air valve 8, the 5th Electric air valve 9, the 6th Electric air valve 10 are in opening, mobile thermal-insulation baffle plate position is in freezer central authorities (between the first air outlet and the second air outlet), the supply air system of two integral type compressor bank is separately independently, the first compressor bank 5HP provides heat exchange for freezer, and the second compressor bank 3HP provides heat exchange for refrigerator.Circulated air enters air-cooled evaporimeter is lowered the temperature by heat exchange and enters in storehouse from air outlet from return air inlet, to realize respectively the effect of the temperature that maintains freezer and refrigerator.
The second pattern, it is fast cooling pattern, the first compressor bank and the first air-cooled evaporimeter are realized heat exchange, the second compressor bank and the second air-cooled evaporimeter are realized heat exchange, the first air-cooled evaporimeter and the second air-cooled evaporimeter provide heat exchange by common air outlet and return air inlet for freezer, and mobile thermal-insulation baffle plate position is in freezer central authorities (between the first air outlet and the second air outlet).
As shown in Figure 3: the first Electric air valve 5, the second Electric air valve 6, the 3rd Electric air valve 7, the 4th Electric air valve 8 are in opening, the 5th Electric air valve 9, the 6th Electric air valve 10 are in closed condition, mobile thermal-insulation baffle plate position is in freezer central authorities (between the first air outlet and the second air outlet), according to using requirement, expand freezer storage capacity, by mobile thermal-insulation baffle plate position near on the position of the second air outlet.When freezer causes storehouse temperature to fluctuate larger in the situation that in fast food freezing, precooling storage and the reason such as artificial, can use this fast-refrigerating pattern.Increase to example with freezer storage capacity, by mobile thermal-insulation baffle plate position near on the position of the second air outlet, can realize freezer by the transformation of 1/3rd to 2/3rds capacity that accounts for freezer total measurement (volume), to meet the storage of new food, now the circulated air of freezer, from return air inlet simultaneously by two typhoon cold type evaporimeter heat exchange coolings, is then all got back in freezer from the air outlet of freezer.The first compressor bank 5HP and the second compressor bank 3HP combine for freezer provides heat exchange, and freezer is carried out to fast cooling.Two-shipper group is combined cooling has increased refrigerating capacity, has reduced the freezing time of cooling of food, and taking cryogenic temperature as-18 DEG C as example, the cooling time 30% of can saving time, has realized quick-frozen effect.When the temperature of freezer reaches after the temperature setting, fast cooling pattern is become to the first pattern (being freezing and refrigeration pattern), use the first compressor bank 5HP to maintain the temperature in freezer.
In freezer fast cooling process, because refrigerator does not carry out exchange heat, can cause refrigerator temperature rise, when refrigerator temperature reaches in limited time, regulate snap frozen pattern to become freezing and refrigeration pattern, after refrigerator temperature drops to target temperature, regulate again freezing and refrigeration pattern to become snap frozen pattern.
The third pattern, it is single freezing or refrigeration pattern, the first compressor bank and the first air-cooled evaporimeter are realized heat exchange, the second compressor bank and the second air-cooled evaporimeter are realized heat exchange, the first air-cooled evaporimeter and the second air-cooled evaporimeter can provide heat exchange for freezer or refrigerator by common return air inlet and air outlet separately, mobile thermal-insulation baffle plate position for example, in a side of freezer (between the first return air inlet and the first air outlet, or between the second air outlet and the second return air inlet).The first air-cooled evaporimeter and the second air-cooled evaporimeter also can be by separately air outlet and return air inlet provide heat exchange for freezer or refrigerator, mobile thermal-insulation baffle plate position is in the rightmost side or the leftmost side of freezer.
In some specific situation, freezer only needs freezing or cold storage function to preserve food, not only can realize the high capacity utilization of freezer by the mobile heat room plate of the online cooperation of two-shipper group for this reason, reduce enclosed structure heat dissipation capacity and save cold, arrange but also can optimize air-flow in storehouse.
As shown in Figure 4: the first Electric air valve 5, the second Electric air valve 6, the 3rd Electric air valve 7, the 4th Electric air valve 8, the 5th Electric air valve 9 are in opening, the 6th Electric air valve 10 is in closed condition, mobile thermal-insulation baffle plate position for example, in freezer one side (between the second air outlet and the second return air inlet), according to using requirement, expand corresponding storage capacity.
Circulated air enters two evaporimeters from the return air inlet of freezer through air-supply passage, after heat exchange cooling, gets back in freezer respectively from the air outlet of freezer and refrigerator, realizes uniform air flow and arranges, reduces the discrete type of temperature of ice house, reduces temperature fall time.
Under single freezing or refrigeration pattern, freezer starts in temperature-fall period under two-shipper group jointly controls, and the first and second compressor bank provide heat exchange jointly; If moveable partition board moves to storehouse body low order end, can be converted to conventional freezing refrigeration pattern, open Electric air valve 7,8,9,10, close Electric air valve 5,6.In the time that storehouse temperature reaches refrigerated storage temperature, close refrigerant condenser group, realize food refrigeratedly, in the time that temperature reaches cryogenic temperature, close refrigeration compressor bank, realize food product refrigeration.
Three kinds of patterns do not isolate, and the optimum performance that has reached freezer is worked in coordination with, switched to three kinds of patterns jointly under certain conditions.For example just start must start fast cooling pattern in food temperature-fall period, while waiting food temperature to reach reserve temperature, opened conventional freezing refrigeration pattern.The operation of this new equipment has certain complexity, can realize the automatic operating that freezer pattern is switched by the control technology of comparative maturity, can carry out by the temperature of PLC controller detection freezer freezer refrigerator the operation conditions of adjusting air valve keying and two-shipper group, save human resources, improve freezer operational efficiency.
Above the present invention is done to exemplary description; should be noted that; in the situation that not departing from core of the present invention, the replacement that is equal to that any simple distortion, amendment or other those skilled in the art can not spend creative work all falls into protection scope of the present invention.
