Description
Technical field
Field of Refrigeration and Air-conditioning is the utility model is related to, particularly the straight-expansion type air conditioner device of the 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 seriously affected 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, the purpose of this utility model is to provide a kind of the straight of the balanced liquid separation of energy
Expansion type air conditioner device.It while ensureing that straight-expansion type air conditioner system liquid separation is uniform, can improve the refrigerating capacity and energy of air-conditioning system
Effect.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
A kind of straight-expansion type air conditioner device of the balanced liquid separation of energy, it is structurally characterized in that, it includes the feed liquor collector being disposed vertically
With the total collector of return-air.Multiple subsystems, each subsystem are equipped with successively from top to bottom between the total collector of the feed liquor collector and return-air
System includes sequentially connected expansion valve, distributor, direct-expansion type heat exchanger, return-air collector, temperature sensor and pressure sensing respectively
Device.The total collector cooled via return air pipe of return-air is drawn.
In above-mentioned straight-expansion type air conditioner device, 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 device, the position of the muffler is placed in the middle and upper part of the total collector of return-air.
Compared with the existing technology, its advantage is the utility model：
（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 utility model is described in further detail with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
Referring to Fig. 1, a kind of straight-expansion type air conditioner device of the balanced liquid separation of energy of the utility model, it includes the feed liquor being disposed vertically
Collector 1 and the total collector 7 of return-air.Multiple subsystems are equipped with successively from top to bottom between feed liquor collector 1 and the total collector 7 of return-air, each
Subsystem includes sequentially connected expansion valve 2, distributor 3, direct-expansion type heat exchanger 4, return-air collector 5,6 and of temperature sensor respectively
Pressure 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 always collects
7 cooled via return air pipe 9 of pipe is drawn, and the position of muffler 9 is placed in the middle and upper part of the total collector 7 of return-air.
In the utility model device, condensed fluid enters from feed liquor collector 1, then flows into each subsystem.Liquid refrigerant
After the expansion valve 2 for flowing through each subsystem throttles, become gas-liquid two-phase state, then the allocated device 3 is flowed changes into direct-expansion type
Hot device 4.It is changed into overheated gas after endothermic gasification in direct-expansion type heat exchanger 4 and enters return-air collector 5.System is overheated in each subsystem
Refrigerant gas is finally aggregated into the total collector 7 of return-air and flows out.
In the utility model structure, the expansion valve 2 in each subsystem can carry out only according to the subsystem return-air degree of superheat
Vertical control, and the control parameter of each expansion valve 2 can be set equally, can also be separately provided according to actual conditions, mutually
Between do not interfere with.Distributor 3 includes liquid-dividing head（Restricting element）And separating tube, the separating tube quantity of each subsystem should not surpass
30 are crossed, 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 utility model can ensure to enter liquid system in each subsystem
Cryogen is basically identical, and two-way difference in height is not much different each subsystem up and down, and branch number is moderate, ensure that distributor point
The uniformity of liquid.Meanwhile this liquid separation technology it is also ensured that air-conditioning system at part load the regulating power of expansion valve and
Precision, improves the area utilization of heat exchanger, increases exchange capability of heat.
