Based on embodiment, present invention is described below, but the present invention is not restricted to these embodiments.In hereafter details of the present invention being described, detailedly describe some specific detail sections.Do not have the description of these detail sections can understand the present invention completely for a person skilled in the art yet.In order to avoid obscuring essence of the present invention, known method, process, flow process, element do not describe in detail.
Present invention also offers a kind of indoor set of multi-gang air-conditioner, comprise indoor heat exchanger, at least one end of described indoor heat exchanger is provided with cut-off equipment, cut-off equipment is used for the refrigerant flow cutting off this indoor set when indoor set power-off.When indoor set power-off, cut-off equipment can cut off the refrigerant flow of power-off indoor set, avoids occurring condensation dripping phenomenon at power-off indoor set place, ensures the normal work running indoor set, improves the functional reliability of multi-gang air-conditioner.
The embodiment of the indoor set of multi-gang air-conditioner provided by the invention is illustrated below in conjunction with accompanying drawing 2 to 5.
Embodiment one:
As shown in Figure 2, indoor set comprises indoor heat exchanger 1 and indoor throttling arrangement 2, one end of indoor heat exchanger 1 is provided with cut-off equipment, in the present embodiment, cut-off equipment is arranged at refrigerant inlet one end when indoor heat exchanger 1 freezes, and cut-off equipment is used for the refrigerant flow cutting off this indoor set when this indoor set power-off, avoids refrigerant to continue to flow in indoor heat exchanger 1 and causes condensation dripping phenomenon, ensure the normal work running indoor set, improve the functional reliability of multi-gang air-conditioner.
As a kind of preferred embodiment, cut-off equipment is the switching device that breakpoint closedown is opened in energising, more preferably magnetic valve 3.
Certainly, be understandable that, cut-off equipment also can heat exchanger 1 disposed in the interior refrigerant exit one end when freezing, and can reach above-mentioned effect equally.
The indoor set of above-mentioned multi-gang air-conditioner, when operation of air conditioner heating mode, although cut-off equipment also can avoid refrigerant to continue flowing after power-off, can accumulate refrigerant in indoor heat exchanger 1, for this problem, provides preferred scheme further.
In a preferred embodiment, as shown in Figure 3, magnetic valve 3 is all set at the two ends of indoor heat exchanger 1, like this, no matter multi-gang air-conditioner is running refrigerating pattern or heating mode, refrigerant all can be avoided to accumulate in indoor heat exchanger 1, further increase the reliability of system.
In a further advantageous embodiment, as shown in Figure 4, one bypass branch 4 is set, bypass branch 4 is for when on refrigerant flow, indoor heat exchanger 1 is positioned at the upstream of cut-off equipment, namely when in the present embodiment, air-conditioning system heats, after indoor set power-off, the refrigerant accumulated in indoor heat exchanger 1 is crossed cut-off equipment and causes in the downstream pipe of cut-off equipment, prevent refrigerant from accumulating in indoor heat exchanger 1 and cause the system failure.
Concrete, bypass branch 4 and cut-off equipment are arranged in parallel.Bypass branch 4 is also provided with check valve 42, and check valve 42 only allows refrigerant to flow to bypass throttle device by indoor heat exchanger 1.
Bypass branch 4 is provided with bypass throttle device, as a kind of preferred embodiment, bypass throttle device is capillary 41, and the length of capillary 41 and caliber set according to indoor heat exchanger 1, thus obtain suitable cold medium flux.Such as, indoor heat exchanger 1 is fin-tube heat exchanger, then the length of its capillary 41 is preferably 100 to 800mm, and internal diameter is preferably 0.9 to 2.4mm.
It is capillary 41 that bypass throttle device is also not limited to, and other can reach the throttling arrangement of restriction effect.
As a kind of preferred embodiment, cut-off equipment is the switching device that breakpoint closedown is opened in energising, more preferably magnetic valve 3.
When multi-gang air-conditioner running refrigerating pattern, the flow direction of refrigerant is magnetic valve 3-indoor throttling arrangement 2-indoor heat exchanger 1; When running heating mode, refrigerant is divided into two-way after indoor heat exchanger 1 and indoor throttling arrangement 2, and a road is through magnetic valve 3, and a road is through check valve 42 and capillary 41.
When the unexpected power-off of indoor set, indoor throttling arrangement 2 keeps the state before power-off, close after magnetic valve 3 power-off, if refrigeration mode, then, refrigerant blocks along the direction of magnetic valve 3, indoor throttling arrangement 2, indoor heat exchanger 1, and capillary 41 and this branch road of check valve 42 are also block under the effect of check valve 42, thus avoids occurring the system failure; If heating mode, then, refrigerant blocks along the direction of indoor heat exchanger 1, indoor throttling arrangement 2, magnetic valve 3, but indoor heat exchanger 1, indoor throttling arrangement 2, check valve 42, this branch road of capillary 41 are circulations, a small amount of refrigerant bypass can be pass by, avoid the accumulation of refrigerant in this indoor heat exchanger 1 and cause the system failure.
In a further advantageous embodiment, as shown in Figure 5, similar shown in its structure and Fig. 4, difference is, refrigerant exit one end when magnetic valve 3 and bypass branch 4 heat exchanger 1 disposed in the interior freeze, when the unexpected power-off of indoor set, indoor throttling arrangement 2 keeps the state before power-off, close after magnetic valve 3 power-off, if heating mode, then, refrigerant blocks along the direction of magnetic valve 3, indoor heat exchanger 1, and capillary 41 and this branch road of check valve 42 are also block under the effect of check valve 42, thus avoid occurring the system failure; If refrigeration mode, then, refrigerant blocks along the direction of indoor throttling arrangement 2, indoor heat exchanger 1, magnetic valve 3, but indoor throttling arrangement 2, indoor heat exchanger 1, check valve 42, this branch road of capillary 41 are circulations, a small amount of refrigerant bypass can be pass by, avoid the accumulation of refrigerant in this indoor heat exchanger 1 and cause the system failure.
For above-mentioned indoor set, present invention also offers a kind of multi-gang air-conditioner, this multi-gang air-conditioner comprises the multiple above-mentioned indoor set be arranged in parallel, and runs more reliable.
Present invention also offers a kind of multi-gang air-conditioner control method, multi-gang air-conditioner comprises the multiple indoor sets be arranged in parallel, when arbitrary indoor set power-off, the refrigerant flow of this indoor set is cut off, avoid occurring condensation dripping phenomenon at power-off indoor set place, ensure the normal work running indoor set, improve the functional reliability of multi-gang air-conditioner.
Further, on refrigerant flow, when the downstream only at indoor heat exchanger arranges the cut-out point cutting off refrigerant flow, the refrigerant in indoor heat exchanger is crossed cut-out point and causes in the downstream pipe of cut-out point, prevent refrigerant from accumulating in indoor heat exchanger and cause the system failure.
