Below specifically describe at first by reference to the accompanying drawings the refrigeration system according to first aspect present invention embodiment.
As shown in Figure 1 to Figure 3, according to the refrigeration system of the embodiment of the present invention, comprise: compressor 10, condenser 30, transfer valve 40, the first evaporimeter 21, the second evaporimeter 22 and the 3rd evaporimeter 23.
Particularly, 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, the first evaporimeter port 41, the second evaporimeter port 42 and the 3rd evaporimeter port 43, condenser port 45 is connected with condensator outlet 302, the first evaporimeter 21 comprises the first entrance 211 and the first outlet 212, the first entrance 211 is connected with the first evaporimeter port 41, the first outlet 212 is connected with the air entry 101 of compressor 10, the second evaporimeter 22 comprises the second entrance 221 and the second outlet 222, the second outlet 222 is communicated with the first entrance 211 of the first evaporimeter 21, the second entrance 221 is communicated with the second evaporimeter port 42, the 3rd evaporimeter 23 comprises the 3rd entrance 231 and the 3rd outlet 232, the 3rd outlet 232 is communicated with the first entrance 211 of the first evaporimeter 21, the 3rd entrance 231 is communicated with the 3rd evaporimeter port 43, wherein, the second evaporimeter 22 and the 3rd evaporimeter 23 are connected in parallel or are connected in series.
Thus, refrigeration system according to the embodiment of the present invention, by transfer valve and a plurality of evaporimeters that are connected with each port of transfer valve respectively are set, transfer valve can be controlled respectively the duty of each evaporimeter, the evaporator operation of different numbers can realize different cryogenic temperatures, thereby the alternating temperature amplitude of refrigeration system is got a promotion, fully meet user's wide cut alternating temperature demand.
It should be noted that, the connected mode of the second evaporimeter 22 and the 3rd evaporimeter 23 can be for being connected in series or being connected in parallel, as long as meet, can realize the requirement of wide cut alternating temperature by controlling different evaporator operation, different evaporator operation can be opened or be closed to control to the first evaporimeter port 41, the second evaporimeter port 42 and the 3rd evaporimeter port 43 as required.Wherein, cold-producing medium is by direction as shown along flowing clockwise, and cold-producing medium constantly circulates in system simultaneously, and state variation occurs, and carries out exchange heat with the external world, and each evaporimeter will flow into liquid evaporation heat absorption wherein, plays the effect of cooling.A plurality of evaporimeters are worked simultaneously, and caloric receptivity is larger, and it is large that cooling extent also can become.
In an embodiment of the present invention, by the related port of regulating transfer valve 40, the second evaporimeter 22 and the 3rd evaporimeter 23 are worked together, can realize that refrigeration system-18 ℃ are to the alternating temperature demand of-7 ℃.By regulating transfer valve 40, while making in the middle of the second evaporimeter 22 and the 3rd evaporimeter 23 to only have a job, can realize that refrigeration system-7 ℃ are to the alternating temperature demand of 10 ℃, thereby realize 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 second entrance 221 and the second evaporimeter port 42 of the second evaporimeter 22.
