Description
Technical field
The present invention relates to the straight-expansion type air conditioner system of field of Refrigeration and Air-conditioning, the particularly balanced liquid separation of energy.
Background technology
At present, the direct-expansion-type heat exchanger used in large-scale refrigerated air-conditioning system, this mode directly to blow into
Row cooling, eliminates a set of refrigeration system, reduces initial cost, while reduces the energy consumption of freezing conveying.But this kind of air-conditioning
The refrigerating capacity of system is all bigger, and the evaporator size of individual system also can be bigger, therefore refrigeration system liquid branch number meeting
Increase, and two-way liquid height difference is larger up and down, has had a strong impact on the uniformity of each pipeline refrigerant inlet liquid distribution, has caused
Heat exchanger performance significantly declines.So cause integral air conditioner system refrigerating capacity and efficiency all than relatively low, directly affects straight
Extensive use and popularization of the expansion type air conditioner system in large public building air-conditioning system.
The content of the invention
For above-mentioned problems of the prior art, it is an object of the invention to provide a kind of direct-expansion type of the balanced liquid separation of energy
Air-conditioning system.It while ensureing that straight-expansion type air conditioner system liquid separation is uniform, can improve the refrigerating capacity and efficiency of air-conditioning system.
The invention will be further described with reference to the accompanying drawings and detailed description.
A kind of straight-expansion type air conditioner system of the balanced liquid separation of energy, it is structurally characterized in that, it includes the feed liquor collector being disposed vertically
With return-air collecting main.Multiple subsystems, each subsystem are equipped with successively from top to bottom between the feed liquor collector and return-air collecting main
System includes expansion valve, distributor, direct-expansion type heat exchanger, return-air collector, temperature sensor and the pressure sensing being sequentially connected respectively
Device.Return-air collecting main cooled via return air pipe is drawn.
In above-mentioned straight-expansion type air conditioner system, the distributor includes a liquid-dividing head and multiple separating tubes, separating tube
Quantity is no more than 30.
In above-mentioned straight-expansion type air conditioner system, the position of the muffler is placed in the middle and upper part of return-air collecting main.
Compared with the existing technology, its advantage is the present invention：
（1）It can guarantee that the uniformity of straight-expansion type air conditioner system liquid separation.
（2）Improve the precision of expansion valve control.
（3）Improve the area utilization of heat exchanger.
The invention will be further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Referring to Fig. 1, a kind of straight-expansion type air conditioner system of the balanced liquid separation of energy of the present invention, it includes the feed liquor collector being disposed vertically
1 and return-air collecting main 7.It is equipped with multiple subsystems, each subsystem between feed liquor collector 1 and return-air collecting main 7 successively from top to bottom
System includes expansion valve 2, distributor 3, direct-expansion type heat exchanger 4, return-air collector 5, temperature sensor 6 and the pressure being sequentially connected respectively
Sensor 8.Distributor 3 includes a liquid-dividing head and multiple separating tubes, and the quantity of separating tube is no more than 30.Return-air collecting main 7
Cooled via return air pipe 9 is drawn, and the position of muffler 9 is placed in the middle and upper part of return-air collecting main 7.
In present system, condensed fluid enters from feed liquor collector 1, then flows into each subsystem.Liquid refrigerant is flowing
After the expansion valve 2 of each subsystem throttles, become gas-liquid two-phase state, then the allocated device 3, which flows, enters direct-expansion type heat exchanger
4.It is changed into overheated gas after endothermic gasification in direct-expansion type heat exchanger 4 and enters return-air collector 5.Superheated refrigerant in each subsystem
Gas is finally aggregated into return-air collecting main 7 and flowed out.
In structure of the present invention, the expansion valve 2 in each subsystem can carry out independent control according to the subsystem return-air degree of superheat
System, and the control parameter of each expansion valve 2 can be set equally, can also be separately provided according to actual conditions, between each other
Do not interfere with.Distributor 3 includes liquid-dividing head（Restricting element）And separating tube, the separating tube quantity of each subsystem is no more than 30
Root, and the refrigerating capacity of each subsystem is also no more than 30 standard tons.
The liquid separation technology of the above-mentioned subsystem independent control of the present invention can ensure to enter liquid refrigerant in each subsystem
It is basically identical, and two-way difference in height is more or less the same each subsystem up and down, and branch number is moderate, ensure that distributor liquid separation
Uniformity.Meanwhile this liquid separation technology it is also ensured that air-conditioning system at part load the regulating power of expansion valve and precisely
Degree, the area utilization of heat exchanger is improved, increase exchange capability of heat.
