This device is connected to air-conditioning system and inserts electric expansion valve and capillary, interior hexagonal in first stop valve 20,24,28,30,34 and 38 control port is separately tightened, thereby electric expansion valve and capillary are isolated from the outside, and then utilize vavuum pump that whole matching system (comprising the inside and outside machine of air-conditioning and this air-conditioner matching device) is vacuumized.When carrying out the capillary match and regulate, the high-pressure stop valve 44 and the low-pressure shutoff valve 46 of reservoir 14 to be closed, disconnection reservoir 14 is connected with air-conditioning system.When carrying out the coupling of cooling medium charging amount, open high-pressure stop valve 44 and low-pressure shutoff valve 46, make reservoir 14 be connected into air-conditioning system.Should note; should be before reservoir 14 is mounted to matching system with air emptying wherein; and the internal pressure when reservoir 14 pressure inside should be shut down with the air-conditioning model machine that will mate is approaching; specifically should remain within the pressure limit according to designing requirement; be the high pressure that reservoir 14 pressure inside should not be higher than this particular pressure range, also should not be lower than the low pressure of this particular pressure range.In addition, before being installed to reservoir 14 in this air-conditioner matching device, also to measure and record the initial weight of reservoir 14.
Carry out the capillary coupling when (capillary is used for the refrigerated medium heat of air-conditioning is carried out throttling control), only open a pair of first stop valve at every turn.For example can at first open first pair first stop valve 20 and 30, utilize electric expansion valve that the combination property of air-conditioning system is mated accurately earlier, after meeting design requirement, close first stop valve 20 and 30, open second pair first stop valve 24 and 34, the capillary that is connected between them is mated, if mate defective, can close this a pair of first stop valve 24 and 34 again, open the 3rd pair first stop valve 28 and 38, the capillary of another size is mated.If the capillary of this size mates qualified then finishes coupling, if capillary defective then that need to change other size mates.When changing the time capillaceous,, and install the capillary of new size with the capillary removal on first stop valve of having closed.After more finishing changing capillary, open any (for example first stop valve 24 being opened) in first stop valve at the capillary two ends in the new connection by control port 24b, and the connectivity port 24a that will link to each other with the other end capillaceous unscrews, utilize the refrigerant in the reservoir 14 that the air in the capillary of this new replacing is discharged, tighten connectivity port 24a subsequently, guarantee that the capillary two ends do not leak, and first stop valve at capillary two ends is all opened.So just finished once replacing capillaceous, in this replacing process, air-conditioning need not to shut down, and has eliminated the stabilization time after air-conditioning is started shooting once more, and because the effect of first stop valve makes that not having extraneous air in the replacing process enters.
When carrying out the adjusting of cooling medium charging amount, increase the cooling medium charging amount if desired, then open second stop valve of the reservoir 14 of capillary low pressure one end that is connected into the coupling path, for example low-pressure shutoff valve 46, and the cold media gas in the reservoir 14 is entered in the air-conditioning system; When needs reduce the cooling medium charging amount, just open second stop valve of the reservoir 14 of capillary high pressure one end, for example high-pressure stop valve 44, and the cold media gas in the air-conditioning system is entered in the reservoir 14.By the various performance parameters of real-time monitored air-conditioning, constantly regulate (increase or reduce) cooling medium charging amount, till the performance that finally reaches the designing institute expectation.This mode of utilizing the cooling medium charging amount in 14 pairs of air-conditioning systems of reservoir to regulate; not only can control the groundwater increment of refrigerant accurately; and prevent to increase or make when reducing refrigerant the probability of air entrained gas; and need not shutdown operation; thereby eliminated the stabilization time of start back air-conditioning once more; simplify the step of matching operation, improved matching efficiency.
After the coupling of cooling medium charging amount finishes, weight to reservoir 14 is carried out weighing, the difference of reservoir 14 weight when relatively initial weight and coupling finish, this difference (recruitment or reduction) is counted in the initial cooling medium charging amount of the air-conditioning model machine that is mated, thereby can determine the cooling medium charging amount that the air-conditioning of model therewith mates most.
Above-mentioned is exactly to utilize the air-conditioner matching device of this preferred embodiment to carry out capillary coupling and the flux matched detailed process of cooling medium charging, and in fact, these two processes are not to carry out according to sequencing, but carry out according to actual match situation intersection.Just should note having only a pair of unlatching in three pairs first stop valves, and at this moment two second stop valves 44 of reservoir 14 and 46 close, just reservoir 14 is isolated outside the coupling path carrying out capillary when coupling.And carrying out cooling medium charging when flux matched, just need two second stop valves 44 and 46 of reservoir 14 be regulated, to increase or to reduce the cooling medium charging amount in the air-conditioning system.In addition, also should pay special attention to, when changing capillary, need temporarily use reservoir 14, just as described above mode with the air emptying in the new capillary.
Be the preferred embodiments of the present invention only below, be not limited to the present invention, for a person skilled in the art, the present invention can have various changes and variation.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
