The structural representation of the refrigeration system of the dispensing cabinet that Fig. 1 provides for the embodiment of the present invention.
Detailed description of the invention
The object of the present invention is to provide a kind of refrigeration system of cabinet of providing and delivering, the structural design of the refrigeration system of this dispensing cabinet can solve the problem cannot carrying out control separately to each bin effectively.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the refrigeration system of the dispensing cabinet that the embodiment of the present invention provides comprises compressor, condenser, knockout, multiple triple valve, multiple evaporimeter and discharge.Wherein, the refrigerant import of condenser is communicated with the refrigerant exit of compressor, and the refrigerant through compressor compression enters in condenser.The import of knockout is communicated with the refrigerant exit of condenser, and refrigerant enters in knockout after condensation within the condenser.Knockout has multiple outlet.Each triple valve has A mouth, B mouth and C mouth, the A mouth of multiple triple valve respectively with multiple outlet of knockout, namely the A mouth of each triple valve all with an outlet of knockout, the A mouth of multiple triple valve and multiple outlet one_to_one corresponding of knockout, refrigerant enters triple valve through A mouth.Triple valve can switch to A mouth and B mouth and be communicated with at least one in C mouth or switch to A mouth and be not all communicated with C mouth with B mouth, and namely refrigerant can flow out from A mouth and/or B mouth after entering from A mouth, or B mouth and C mouth are all closed, and refrigerant can not flow out from triple valve.B mouth and the C mouth of each triple valve are all communicated with evaporimeter, the refrigerant inlet communication of B mouth and C mouth and evaporimeter, and namely each triple valve correspondence connects two evaporimeters, and two evaporimeters that each triple valve is corresponding are communicated with C mouth with the B mouth of triple valve respectively.The import of discharge is communicated with the refrigerant exit of evaporimeter, the outlet of discharge and the refrigerant inlet communication of compressor.
When applying the refrigeration system of the dispensing cabinet that the embodiment of the present invention provides, be connected by multiple triple valve between knockout with multiple evaporimeter, and each triple valve correspondence connects two evaporimeters, triple valve can switch to A mouth and B mouth and be communicated with at least one in C mouth or switch to A mouth and be not all communicated with C mouth with B mouth, whether so can control connected two evaporimeters by triple valve has refrigerant to pass through, and then connected two evaporimeters can be controlled by a triple valve and whether freeze, all evaporimeters can be controlled eventually through multiple triple valve whether to freeze, achieve the independent control to multiple evaporimeter, namely can only freeze by a part of evaporimeter, another part does not then freeze.If there is vacant bin, then the evaporimeter that can control to be connected with this bin does not circulate refrigerant, comparatively saves the energy.
In order to optimize technique scheme further, be wherein all serially connected with throttling element between B mouth and evaporimeter and between C mouth and evaporimeter, namely refrigerant enters in evaporimeter after need flowing through throttling element, so can improve heat exchange efficiency further.For the ease of assembling, throttling element can be capillary, can also be choke valve certainly, in this no limit.
Because multiple bins of cabinet of providing and delivering generally divide multilayer to arrange from top to bottom, therefore the position height of multiple capillary and multiple evaporimeter is also different, so identical in order to ensure the coolant quantity flowed in multiple evaporimeter, can the length of capillary from high to low reduce gradually, and the length being positioned at the capillary of sustained height is equal, the capillary pipe length that the capillary that namely position is the highest is minimum to position reduces gradually.
In the present embodiment, dispensing cabinet comprises multiple bin, multiple bin divides Multi-layers distributing from top to bottom, multiple evaporimeter divides Multi-layers distributing from top to bottom, each evaporimeter correspondence refrigeration bin, the capillary connected by the evaporimeter of the superiors reduces gradually to the length of the capillary that undermost evaporimeter connects, and ensure that the coolant quantity flowed in multiple evaporimeter is identical equally.The length of the capillary that the evaporimeter being wherein positioned at same layer connects is equal.
Particularly, the quantity of bin is six, divides three layers of distribution from top to bottom, and the length of the capillary of the evaporimeter connection in middle level is less than the length of the capillary of the evaporimeter connection on upper strata, and is greater than the length of the capillary of the evaporimeter connection of lower floor.So ensure that the refrigeration of multiple bin is identical, there will not be relatively large deviation, and can fast-refrigerating be realized.Corresponding, the quantity of triple valve is three, and the quantity of evaporimeter is six, and the quantity of capillary is also six.Certainly, the quantity of triple valve can also be more, and the quantity of evaporimeter also can be more, in this no limit.
In addition, triple valve can be specially three-way solenoid valve, and the duty of three-way solenoid valve is by step motor control, namely step motor control three-way solenoid valve is in A mouth and B mouth with at least one state be communicated with in C mouth or switch to all disconnected state of A mouth and B mouth and C mouth.Certainly, triple valve also can Non-follow control, in this no limit.
Wherein, the quantity of discharge can be two, and multiple evaporimeter like this can select suitable discharge to connect, to simplify the layout of pipeline nearby.The quantity of discharge also can be one, three etc., in this no limit.
For the ease of assembling, wherein evaporimeter can be plate pipe evaporator, and certain evaporimeter can also be other form structure, in this no limit.
Further, condenser can be turn fin condenser, to ensure heat exchange efficiency.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
