The cooling procedure of extremely cold storeroom 10 to the embodiments of the invention with said structure describes.
First, input temperature for extremely cold instruction or extremely cold storeroom if be judged as higher than design temperature, automatically carried out utmost point blowdown firing.Utmost point blowdown firing refers to that cold-producing medium is converted to the freeze cycle running of cold-producing medium to above-mentioned extremely cold evaporimeter 13 1 side flow to the freeze cycle of main evaporator 18 1 side flow.Above-mentioned extremely cold evaporimeter 13 is connected side by side with above-mentioned main evaporator 18, thereby by switch operating or the regulation of transfer valve, controls cold-producing medium to above-mentioned extremely cold evaporimeter 13 1 side flow.Or, also need to be undertaken refrigerant circulation by above-mentioned main evaporator 18 at the state of the load increase in refrigerating chamber and refrigerating chamber, can be by the aperture of control valve, make a part for cold-producing medium to above-mentioned main evaporator 18 1 side flow, and make a residue part for cold-producing medium to above-mentioned extremely cold evaporimeter 13 1 side flow.As other method, before beginning is extremely cold, first, make cold-producing medium to above-mentioned main evaporator 18 1 side flow, temperature of refrigerating chamber is carried out to supercooling with the temperature lower than design temperature, by extremely above-mentioned extremely cold evaporimeter 16 1 sides of the flow transition of cold-producing medium, carry out extremely cold afterwards.
If cold-producing medium is to above-mentioned extremely cold evaporimeter 16 1 side flow, by cooling with design temperature the temperature of the inside of above-mentioned extremely cold vaporization chamber 13, the above-mentioned extremely cold storeroom fan 14 that is contained in said fans case 131 will be worked, along with above-mentioned extremely cold storeroom fan 14 is worked, the cold air of the inside of above-mentioned extremely cold vaporization chamber 13 is discharged to the inside of above-mentioned extremely cold storeroom 10.The cold air of now, discharging is directed into above-mentioned receiver 121 1 sides by the back side of above-mentioned housing 11.And the part in the cold air hole 124 forming at the back side of above-mentioned receiver 121 can play the function of cold gas exhausting outlet.Here, above-mentioned extremely cold vaporization chamber 13 temperature can be dropped to the operation time that the design temperature moment is afterwards made as above-mentioned extremely cold storeroom fan 14, also cold-producing medium can be started to be made as to the above-mentioned extremely cold mobile moment of evaporimeter 16 operation time of above-mentioned extremely cold storeroom fan 14.
On the other hand, the cold air that is supplied to above-mentioned receiver 121 returns to above-mentioned extremely cold vaporization chamber 13 by above-mentioned cold air hole 124 and above-mentioned return-air grid 132.And above-mentioned extremely cold vaporization chamber 13 separates completely with the evaporator main chamber 31 of accommodating above-mentioned main evaporator 18.Therefore, the cold air of the above-mentioned evaporator main chamber 31 that temperature is relatively high can not flow into above-mentioned extremely cold vaporization chamber 13, can at short notice extremely cold vaporization chamber 13 be cooled to design temperature.
Fig. 4 is the longitudinal section that the refrigerator of the extremely cold vaporization chamber structure of another embodiment of the present invention is shown.
With reference to Fig. 4, the structure of the extremely cold vaporization chamber of the present embodiment is identical with embodiment above, is just all contained in the structure of inside of above-mentioned extremely cold storeroom 10 difference to some extent at above-mentioned extremely cold vaporization chamber 13.
Particularly, the back side and the above-mentioned main grate 15 that form the housing 11 of above-mentioned extremely cold storeroom 10 are close to, and above-mentioned extremely cold vaporization chamber 13 is contained in the inside of above-mentioned housing 11 completely.Therefore,, because above-mentioned extremely cold vaporization chamber 13 is positioned at the inside of above-mentioned housing 11, have advantages of that heat-insulating property improves.
In other words, in the structure shown in Fig. 3, the vaporization chamber wall of accommodating above-mentioned extremely cold evaporimeter 16 contacts with the inner air of above-mentioned refrigerating chamber 20 substantially, thereby can be by a part for the cold air of above-mentioned extremely cold vaporization chamber 13 for cooling above-mentioned refrigerating chamber 20.But in the present embodiment, above-mentioned extremely cold vaporization chamber 13 is completely only for the inside of cooling above-mentioned housing 11, i.e. extremely cold storeroom.
On the other hand, main evaporator illustrated in the embodiment of above-mentioned Fig. 1 to Fig. 4 18 can be considered as to the first evaporimeter, extremely cold evaporimeter 16 is considered as to the second storeroom.And, above-mentioned refrigerating chamber 20 can be considered as to the first storeroom, the above-mentioned extremely cold storeroom 10 that is formed at above-mentioned refrigerating chamber 20 is considered as to the second storeroom.
