Technical field
The utility model relates to the air conditioner technical group field, relate in particular to a kind of be used for the air-conditioning unit vacuumize the fluoridize device.
Background technology
Manufacturing in the process of air-conditioning unit, vacuumizing fluoridize is a very crucial procedure, has only incoagulable gas and the moisture content extracted out as much as possible in the Crew Cooling System, could guarantee the high efficiency and the stability of unit operation.Because when containing too much incoagulable gas in the Crew Cooling System, the pressure at expulsion during unit operation can be higher, thereby cause the refrigerating capacity of unit to descend, and the operation power consumption increases, and the efficient of unit operation reduces.When containing too much moisture content in the Crew Cooling System, not only can reduce the efficient of unit operation equally, also can corrode unit compressor electric motor coil, make the compressor lubrication deterioration of oil, have a strong impact on the service life and the operation stability of compressor, it is stifled that too much moisture content also can cause Crew Cooling System that ice takes place, and causes the consequence that can't move.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of air-conditioning unit to vacuumize the fluoridize device, do not exist to vacuumize the dead angle, vacuumize fluoridize efficient height, guarantee the efficient operation of air-conditioning unit.
For solving the problems of the technologies described above, the technical solution of the utility model is: the air-conditioning unit vacuumizes the fluoridize device, comprises first branch road that is used to connect refrigerant cylinder, and described first branch road is provided with first valve; Be used to connect second branch road of air-conditioning unit low-pressure port, described second branch road is provided with second valve; Be used to connect the 3rd branch road of air-conditioning unit high pressure port, described the 3rd branch road is provided with the 3rd valve; Described first branch road, second branch road and the 3rd branch road are connected in parallel, and are provided with the 4th valve between second valve of described second branch road and the 3rd valve of the 3rd branch road, are connected with vavuum pump by pipeline between described the 3rd valve and the 4th valve.
As a kind of improvement, the pipeline between described vavuum pump and the 3rd valve and the 4th valve is provided with the vacuscope that is used to detect vacuum in the described pipeline.
As further improvement, be provided with the 5th valve between described vavuum pump and the vacuscope.
After having adopted technique scheme, the beneficial effects of the utility model are: owing to designed first branch road that is connected in parallel, second branch road and the 3rd branch road, and first branch road, second branch road and the 3rd branch road are respectively equipped with first valve, second valve and the 3rd valve, be provided with the 4th valve between second valve of second branch road and the 3rd valve of the 3rd branch road, be connected with vavuum pump by pipeline between the 3rd valve and the 4th valve, vavuum pump is in the process that vacuumizes, unlatching that can be by valve or close the break-make of controlling branch road, vacuumize in order, and can guarantee the vacuum between each branch road valve and the vavuum pump, do not have and vacuumize the dead angle, and be that vavuum pump is being taken out always under the state of negative pressure at machine set system, in machine set system, added and just stopped vavuum pump after a certain amount of cold-producing medium reaches malleation, so the probability that outside air infiltrates in the machine set system in the whole process drops to minimum, guarantee the requirement of unit condition of high vacuum degree, guaranteed the efficient operation of whole air-conditioning unit simultaneously.
Owing to be provided with vacuscope between vavuum pump and the 3rd valve and the 4th valve, the vacuum that can reflect system intuitively, feed back to the clear and definite information of operator, the operator can make different reactions according to this information, to guarantee the performance of whole vacuum extractor.
Owing to be provided with the 5th valve between vavuum pump and the vacuscope, can be after vacuumizing end, close the 5th valve, after waiting for a period of time, change numerical value by the detected vacuum of vacuscope, can judge whether the amount that contains incoagulable gas and moisture content in the system is up to standard, and can judge in advance whether system has leakage.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the fundamental diagram of the utility model embodiment;
Among the figure: 1, vavuum pump, 2, the air-conditioning unit, 21, low-pressure port, 22, high pressure port, 3, refrigerant cylinder, 4, first valve, 5, second valve, the 6, the 3rd valve, the 7, the 4th valve, 8, vacuscope, the 9, the 5th valve.
The specific embodiment
As shown in drawings, a kind of air-conditioning unit vacuumizes the fluoridize device, comprises first branch road that is used to connect refrigerant cylinder 3, and described first branch road is provided with first valve 4; Be used to connect second branch road of air-conditioning unit 2 low-pressure ports 21, described second branch road is provided with second valve 5; Be used to connect the 3rd branch road of air-conditioning unit 2 high pressure port 22, described the 3rd branch road is provided with the 3rd valve 6; Described first branch road, second branch road and the 3rd branch road are connected in parallel, and are provided with the 4th valve 7 between second valve 5 of described second branch road and the 3rd valve 6 of the 3rd branch road, are connected with vavuum pump 1 by pipeline between described the 3rd valve 6 and the 4th valve 7.As long as according to the order Open valve, just can in operating process, realize vacuumizing thoroughly, fluoridize is effective.
