Abstract
The utility model discloses a water flow control structure of a water-cooling multi-split type unit, the water-cooling multi-split type unit comprises a sleeve pipe, a water inlet pipe and a water outlet pipe are installed on the sleeve pipe, the sleeve pipe is connected with an exhaust pipe of a compressor through an exhaust communicating pipe of the compressor, the water flow control structure comprises a by-pass pipe and two-way valves, the by-pass pipe and the two-way valves are installed on the water outlet pipe connected with the sleeve pipe, and the two two-way valves are arranged at the two ends of the by-pass pipe in a bridge connection mode. Due to the fact that the two two-way valves are arranged at the two ends of the by-pass pipe in the bridge connection mode and are parallel with the by-pass pipe, when an environment changes and condensing pressure of the unit needs adjusting, the adjustment of the condensing pressure can be achieved through controlling the water flow passing through the sleeve pipe, moreover the control of the water flow is completed through the by-pass pipe and the two two-way valves, so that the condensing pressure of the system can be controlled accurately, the effect that the unit operates in an optimal state is ensured, and not only is temperature control accuracy of the unit improved, but also unit efficiency is improved, unit safety is ensured, energy consumption is reduced, and energy is saved.
Description
Technical field
The utility model relates to the air-conditioning products technical field, is specifically related to a kind of discharge control structure of Water-cooling multi-connected unit.
Background technology
The multiple unit is to drag many modes, it is that a main frame drives several indoor sets, what adopt is frequency-changeable compressor, and most of multiple central air conditioner unit can be regulated between 10-130% automatically, and it has the advantages such as effective, that efficient is high, power consumption is low.Present employed Water-cooling multi-connected unit, special design is not used for control through the scheme of the discharge of sleeve pipe, and therefore, the discharge of sleeve pipe is basicly stable.So just may cause following problem: because the working environment of air-conditioning unit changes, therefore, unit may need sometimes that in the course of the work larger condensing pressure is arranged, and just needs less discharge and will obtain larger condensing pressure; In the time of other, then need less condensing pressure, obtain the discharge that less condensing pressure then will be larger.Conventional rack can not be regulated owing to discharge, therefore condensing pressure can not correspondingly be regulated, so just may cause the unit can not be with the state work of coupling, not only cause unit that temperature controlled accuracy is decreased, control accuracy such as conventional rack is generally ± and 1 ℃, one twice the temperature difference almost can be ignored really for the impact of common life area, yet but is very large for the impact in some accurate places, as to strict laboratory of temperature requirement etc.; Also can increase in addition the energy consumption of unit.
The utility model content
The technical problems to be solved in the utility model provides a kind ofly makes that the unit control accuracy is higher, better effects if, more energy-conservation Water-cooling multi-connected unit discharge control structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Water-cooling multi-connected unit discharge control structure, this Water-cooling multi-connected unit comprises sleeve pipe, sleeve pipe is equipped with water inlet pipe and outlet pipe, sleeve pipe is also by being connected with the blast pipe of compressor compressor air-discharging communicating pipe, and be provided with cold-producing medium effuser for the cold-producing medium water conservancy diversion, it is characterized in that: this discharge control structure partly comprises bypass pipe and two-port valve, on the outlet pipe that bypass pipe and two-port valve are installed in sleeve pipe is connected, two ends and bypass pipe that two-port valve is connected across bypass pipe form parallel construction.
Preferably, described two-port valve comprises two, is respectively two-port valve one and two-port valve two, and two-port valve one and two-port valve two independently are connected across separately the bypass pipe two ends and form parallel construction with bypass pipe.
Preferably, the bore of described two-port valve one is less than the bore of bypass pipe.
Preferably, the bore of described two-port valve two is less than the bore of two-port valve one.
The utility model passes through at two two-port valves arranged side by side with bypass pipe of the two ends of bypass pipe cross-over connection; change and when need regulating the condensing pressure of unit at environment; discharge by control process sleeve pipe can realize regulating condensing pressure; make condensing pressure satisfy the requirement of environment; and control discharge is finished by bypass pipe and two two-port valves; condensing pressure that so can accuracy-control system; guarantee that unit always moves with the state of the best; both can improve unit to the control accuracy of temperature; can improve unit efficiency again; guarantee unit safety, reduce energy consumption, energy savings.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, 1 is compressor air-discharging communicating pipe, and 2 is that sleeve pipe two, 3 is that sleeve pipe one, 4 is the cold-producing medium effuser, and 5 is water inlet pipe, and 6 is outlet pipe, and 7 is bypass pipe, and 8 is that two-port valve two, 9 is two-port valve one.
The specific embodiment
In the present embodiment, with reference to Fig. 1, described Water-cooling multi-connected unit discharge control structure, this Water-cooling multi-connected unit comprises sleeve pipe 1, sleeve pipe 22, two groups of sleeve pipes are equipped with water inlet pipe 5 and outlet pipe 6, two groups of sleeve pipes also are provided with the cold-producing medium effuser 4 for the cold-producing medium water conservancy diversion in addition also by being connected with the blast pipe of compressor compressor air-discharging communicating pipe 1; The discharge control structure partly comprises bypass pipe 7 and two-port valve, and bypass pipe 7 is installed on the outlet pipe 6 that is connected with sleeve pipe, and two ends and bypass pipe 7 that two-port valve is connected across bypass pipe 7 form parallel construction.
Two-port valve comprises two, is respectively two-port valve 1 and two-port valve 28, and two-port valve 1 and two-port valve 28 independently are connected across separately bypass pipe 7 two ends and form parallel construction with bypass pipe 7.
The bore of two-port valve 1 is less than the bore of bypass pipe 7.
The bore of two-port valve 28 is less than the bore of two-port valve 1.
When cooling system moves, control the opening and closing of two-port valve 1 and two-port valve 29 by the condensing pressure of detection system.
When condensing pressure was higher, two-port valve 1 was opened, and discharge increases, and condensing pressure descends, if condensing pressure still fails to meet the demands, then continued to open two-port valve 28, and discharge further increases, and condensing pressure is met the demands;
When condensing pressure is relatively lower, close two-port valve 1, discharge reduces, and condensing pressure improves, if condensing pressure fails to meet the demands, continues to close two-port valve 28, and discharge further reduces, and condensing pressure is met the demands; So, but the condensing pressure of accuracy-control system, assurance unit safety, efficiently operation.
Below the utility model is described in detail, the above only is the preferred embodiment of the utility model, when not limiting the utility model practical range, be allly to do impartial change and modify according to the application's scope, all should still belong in the utility model covering scope.
