Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.
According to an aspect of the present invention, provide a kind of liquid feed device, as shown in Figure 2, this liquid feed device comprises: feed tube 10; Separating tube 20, is connected with feed tube 10, and separating tube 20 is flatly arranged vertically; Many drain pipes 30, are connected with the cavity of separating tube 20 at intervals, and the level height of the communications ports be connected with the cavity of separating tube 20 of drain pipe 30 is lower than the floor level height of the liquid level in cavity.
In separating tube 20, liquid refrigerants can be gathered in the bottom of cavity, and gaseous coolant can be gathered in the top of cavity, because the level height of the communications ports between many drain pipes 30 and separating tube 20 is lower than the floor level height of the liquid level in the cavity of separating tube 20, so the liquid refrigerants being gathered in the bottom of separating tube 20 can preferentially enter drain pipe 30.Liquid feed device of the present invention can under the disadvantageous conditions such as lack of refrigerant, feed flow deficiency, pressure drop shwoot normal feed flow; drain pipe 30 is air-cooler feed flow continuously; ensure the normal operation of air-cooler, and gas can be avoided to enter heating power expansion valve, for heating power expansion valve provides protection.
Preferably, the level height of the communications ports of many drain pipes 30 is consistent.Liquid feed device of the present invention is in order to each air-cooler supply liquid refrigerants, so many drain pipes 30 are consistent with the level height of the communications ports of separating tube 20 can ensure that refrigerant can enter each drain pipe 30 equably and be supplied to each air-cooler.
Preferably, the communications ports of drain pipe 30 is connected with the bottom of cavity.Preferably, drain pipe 30 comprises: first paragraph 31, and its first end is connected with the bottom of separating tube 20; Second segment 32, takes the shape of the letter U, and its first end is connected with the second end of first paragraph 31; 3rd section 33, its first end is connected with the second end of second segment 32, and second end of the 3rd section 33 extends upward.Preferably, second end of the 3rd section 33 extends to more than the level height of separating tube 20 upward.After certain air-cooler quits work, the second segment 32 of the U-shaped of the drain pipe 30 corresponding with this air-cooler can also store a part of refrigerant, like this when this air-cooler runs again, directly can suck the refrigerant of second segment 32 storage, and can not suction gas thus affect air-cooler work.
Preferably, liquid feed device also comprises on-off valve 40, and on-off valve 40 is arranged on drain pipe 30.When air-cooler quits work or work abnormal, can close the on-off valve 40 on the drain pipe 30 corresponding with this air-cooler, to cut off the feed flow to this air-cooler, and this operation can not affect the operation of other air-coolers.
Preferably, on-off valve 40 is arranged on the 3rd section 33.
Preferably, liquid feed device comprises four drain pipes 30.Liquid-supplying system is four air-cooler feed flows by four drain pipes 30.
According to another aspect of the present invention, additionally provide a kind of refrigeration unit, comprise condenser and air-cooler, refrigeration unit also comprises above-mentioned liquid feed device, and condenser is to feed tube 10 feed flow of liquid feed device, and the drain pipe 30 of liquid feed device is to air-cooler feed flow.
When refrigeration unit is normally run at full capacity, the separating tube 20 of liquid feed device should be the state being full of liquid, but when refrigeration unit operation at part load or when operating in bad working environments, separating tube 20 is not full liquid status.Liquid feed device of the present invention can ensure that liquid refrigerants can enter into drain pipe 30 under gravity in time, and what to avoid in drain pipe 30 flowing is refrigerant for being mixed with gas, thus ensures that refrigeration unit can reliably, reposefully be run.
Preferably, refrigeration unit also comprises expansion valve, and expansion valve is arranged between liquid feed device and air-cooler.
Preferably, the quantity of drain pipe 30 and the quantity of air-cooler consistent.Many is multiple air-cooler feed flow with drain pipe 30 correspondingly.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
