First the refrigeration system of embodiment is according to a first aspect of the present invention specifically described by reference to the accompanying drawings below.
As shown in Figure 1 to Figure 3, comprise according to the refrigeration system of the embodiment of the present invention: compressor 10, condenser 30, transfer valve 40, first evaporimeter 21, second evaporimeter 22 and the 3rd evaporimeter 23.
Specifically, compressor 10 comprises air entry 101 and exhaust outlet 102, condenser 30 comprises condenser inlet 301 and condensator outlet 302, condenser inlet 301 is connected with the exhaust outlet 102 of compressor 10, transfer valve 40 comprises condenser port 45, first evaporimeter port 41, second evaporimeter port 42 and the 3rd evaporimeter port 43, condenser port 45 is connected with condensator outlet 302, first evaporimeter 21 comprises the first entrance 211 and the first outlet 212, first entrance 211 is connected with the first evaporimeter port 41, first outlet 212 is connected with the air entry 101 of compressor 10, second evaporimeter 22 comprises the second entrance 221 and the second outlet 222, second outlet 222 is communicated with the first entrance 211 of the first evaporimeter 21, second entrance 221 is communicated with the second evaporimeter port 42, 3rd evaporimeter 23 comprises the 3rd entrance 231 and the 3rd outlet 232, 3rd outlet 232 is communicated with the first entrance 211 of the first evaporimeter 21, 3rd entrance 231 is communicated with the 3rd evaporimeter port 43, wherein, second evaporimeter 22 and the 3rd evaporimeter 23 are connected in parallel or are connected in series.
Thus, according to the refrigeration system of the embodiment of the present invention, by arranging transfer valve and multiple evaporimeter be connected with each port of transfer valve respectively, transfer valve can control the duty of each evaporimeter respectively, the evaporator operation of different number can realize different cryogenic temperatures, thus the alternating temperature amplitude of refrigeration system is got a promotion, fully meet the wide cut alternating temperature demand of user.
It should be noted that, the connected mode of the second evaporimeter 22 and the 3rd evaporimeter 23 can for being connected in series or being connected in parallel, as long as meet the requirement that can realize wide cut alternating temperature by controlling different evaporator operation, the first evaporimeter port 41, second evaporimeter port 42 and the 3rd evaporimeter port 43 can be opened or close to control different evaporator operation as required.Wherein, cold-producing medium is by direction as shown along clockwise flow, and cold-producing medium constantly circulates in systems in which simultaneously, state change occurs, carries out exchange heat with the external world, the liquid evaporation endothermic that each evaporimeter will flow into wherein, play the effect of cooling.Multiple evaporimeter works simultaneously, then recept the caloric larger, cooling extent also can become large.
In an embodiment of the present invention, by regulating the related port of transfer valve 40 to make the second evaporimeter 22 work together with the 3rd evaporimeter 23, the alternating temperature demand of refrigeration system-18 DEG C to-7 DEG C can be realized.By regulating transfer valve 40, when making to only have one to work in the middle of the second evaporimeter 22 and the 3rd evaporimeter 23, the alternating temperature demand of refrigeration system-7 DEG C to 10 DEG C can be realized, thus realizing the wide cut alternating temperature demand of refrigeration system.
Alternatively, as shown in Figure 1, according to one embodiment of present invention, the second evaporimeter 22 and the 3rd evaporimeter 23 are connected in series, and the 3rd outlet 232 of the 3rd evaporimeter 23 is located between the second entrance 221 of the second evaporimeter 22 and the second evaporimeter port 42.
In other words, second entrance 221 of the second evaporimeter 22 exports 232 with the second evaporimeter port 42 with the 3rd of the 3rd evaporimeter 23 respectively and is connected, when only needing use the second evaporimeter 22, open the second evaporimeter port 42, cold-producing medium passes through and is circulated in the first evaporimeter 21 from the second evaporimeter 22, now, the extent of alternating temperature of refrigeration system is between-7 ~ 10 DEG C.When needs use the second evaporimeter 22 and the 3rd evaporimeter 23 simultaneously, the second evaporimeter port 42 and the 3rd evaporimeter port 43 can be opened, some refrigerant directly flows in the second evaporimeter 22 from the second evaporimeter port 42, another part cold-producing medium first flows in the 3rd evaporimeter 23 from the 3rd evaporimeter port 43, then flows into from the 3rd evaporimeter 23 in second evaporimeter 22; Also only can open the 3rd evaporimeter port 43, cold-producing medium flows in the 3rd evaporimeter 23 from the 3rd evaporimeter port 43, then flows into from the 3rd evaporimeter 23 in second evaporimeter 22, and now, the extent of alternating temperature of refrigeration system is between-18 ~-7 DEG C.
Thus, only need the related port by simply opening or closing transfer valve 40, refrigeration system can realize the wide cut alternating temperature demand of-18 DEG C to 10 DEG C very easily, implementation efficiency is high, and owing to being multiple evaporator operation, the time that refrigeration expends is short, and manufacturing cost relative moderate.
As shown in Figure 2, the connected mode of the second evaporimeter 22 and the 3rd evaporimeter 23 also can for being connected in parallel.When the second evaporimeter 22 and the 3rd evaporimeter 23 are connected in parallel, if open the 3rd evaporimeter port 43 and the second evaporimeter port 42 simultaneously, cold-producing medium flows in the first evaporimeter 21 respectively from the second evaporimeter 22 and the 3rd evaporimeter 23, first evaporimeter 21, second evaporimeter 22 and the 3rd evaporimeter 23 work simultaneously, and the extent of alternating temperature of refrigeration system is between-18 ~-7 DEG C.
When only having one to open in the second evaporimeter port 42 and the 3rd evaporimeter port 43, cold-producing medium then can only flow in the first evaporimeter 21 from the second evaporimeter 22 and the 3rd evaporimeter 23, that is, in this condition, only have two evaporimeters to work simultaneously, now, the extent of alternating temperature of refrigeration system is between-7 ~ 10 DEG C.
Be understandable that, the concrete number of evaporimeter can need the alternating temperature amplitude reached to carry out reasonable adjusting according to refrigeration system, alternatively, according to one embodiment of present invention, refrigeration system also comprises: the 4th evaporimeter 24,4th evaporimeter 24 is located between the first evaporimeter 21 and transfer valve 40, and the 4th evaporimeter 24 and the second evaporimeter 22 and the 3rd evaporimeter 23 are connected in parallel or are connected in series.
