Abstract
The invention discloses a safe operation performance test method for an air-conditioning compressor used in a high-speed car. The method comprises the following steps: (1) testing the performance of the air-conditioning system under severe conditions in a performance laboratory; (2) covering the compressor of the air-conditioning system with dry ice under atmospheric conditions, vaporizing and cooling the compressor by the dry ice to keep the refrigerant of the lubricating oil in the compressor in a sleep state; (3) restarting the refrigerating system of the air-conditioning system after the compressor is cooled by the dry ice; (4) stopping the air-conditioning system and recording the oil mass and the concentration of the lubricating oil in the compressor; and (5) the oil mass and the concentration of the lubricating oil in the compressor are not less than the minimal values of the oil mass and the concentration of the lubricating oil needed for safe operation of the compressor. In the method, effective actions for preventing the refrigerant from sleeping and effective oil return actions can be taken according to the test results, thus ensuring the lubricating oil concentration essential for normal operation of the compressor and ensuring the operation reliability of the compressor.
Description
Technical field
The present invention relates to a kind of air-conditioning system performance test methods, especially a kind of method for testing safe running performance of high speed vehicle air conditioner compressor.
Background technology
In the speed car air-conditioning system, the compressor lubricant oil course of work is: compressor operation, and parts of lubricating oil sucks from compressor bottom oil groove, is transported to bearing of compressor, Moving plate etc. through oil guide groove and locates lubricate; Parts of lubricating oil flows the discharge compressor with cold-producing medium, participates in the refrigerant system circulation.Whether lubricating of compressor be good, is decided by concentration of lubricating oil, and insufficient lubrication will increase the failure rate of compressor.
Compressor and freeze oil circulating system designing quality usually after equipment puts into operation for a long time, by to system the operation troubles record analysis reach a conclusion, the hidden danger of insufficient lubrication can not be able to prior control in the design phase.
Summary of the invention
When the technical problem to be solved in the present invention provides in a kind of speed car air-conditioning system compressor and unit matching running, the method for testing safe running performance of high speed vehicle air conditioner compressor of the concentration of lubricating oil of test compression machine is to verify and to guarantee the reliability of compressor operating.
For solving the problems of the technologies described above, the technical solution used in the present invention is: (1), in the performance of performance test indoor test air-conditioning system under abominable situation; Described abominable situation is meant that air-conditioning system turns round respectively under the situation of 10 ℃～15 ℃ and 32 ℃～50 ℃;
(2), under atmospheric conditions, the compressor of air-conditioning system is covered, the dry ice evaporates cooling compressor makes the cold-producing medium of compressor inside be in slumber with dry ice; Described slumber is meant under low temperature condition, makes the condensation of refrigerant in the compressor and incorporates in the lubricating oil fully;
(3), above-mentioned compressor after dry ice cooling, the refrigeration system of air-conditioning restarts operation;
(4), above-mentioned air-conditioning system is shut down the oil mass of lubricating oil and the concentration of lubricating oil in the recording compressed machine;
(5), above-mentioned compressor lubricant oil oil mass and concentration should be not less than the required lubricating oil oil mass of compressor safe operation and the minimum of concentration.
Adopt the beneficial effect that technique scheme produced to be: the present invention is the performance of testing air conditioner system under abominable situation at first, whether reach design standards to test it, make cold-producing medium be in slumber under dry ice cooling then, whether the supply/demand of testing its lubricating oil conformance with standard.The present invention passes through compressor lubricant oil oil mass and measurement of concetration result; can take effectively to prevent that cold-producing medium is sunk into sleep and effectively oil return measure according to test result; as increase the liquid way solenoid valve, improve effective measures such as refrigeration system cloth form of tubes; guarantee the refrigeration system good oil return and prevent that cold-producing medium from moving when unit is shut down for a long time in compressor; thereby guarantee the necessary concentration of lubricating oil of the normal operation of compressor, guarantee the functional reliability of compressor.
Embodiment
This method for testing safe running performance of high speed vehicle air conditioner compressor adopts following step:
(1), in the performance of performance test indoor test air-conditioning system under abominable situation, promptly air-conditioning system turns round under the situation of 10 ℃～15 ℃ and 32 ℃～50 ℃ respectively, judges whether it reaches designing requirement.Air-conditioning system has certain performance index under abominable situation when design, by detecting the working order of air-conditioning system under above-mentioned two temperature, can learn whether this air-conditioning system reaches designing requirement.When every index of air-conditioning system reaches design objective, carry out following further test.
(2), under atmospheric conditions, the compressor of air-conditioning system is covered, the dry ice evaporates cooling compressor makes the cold-producing medium in the lubricating oil of compressor inside be in slumber with dry ice; Described cold-producing medium slumber is under low temperature condition, and the condensation of refrigerant in the compressor is also incorporated in the lubricating oil fully.When cooling off with dry ice; can pass through the switching of the electromagnetic valve coil of control system liquid pipe; management to liquid pipe solenoid valve enforcement " pass " and " opening " two kinds of patterns can detect under stopped status, and " pass " of liquid pipe solenoid valve and " opening " are to the lubricated influence of system.
(3), above-mentioned compressor after dry ice cooling, the refrigeration system of air-conditioning restarts operation; Detect the operational situation of compressor when the cold-producing medium slumber.
(4), above-mentioned air-conditioning system is shut down the oil mass of lubricating oil and the concentration of lubricating oil in the recording compressed machine; The oil mass of lubricating oil can be by the view window range estimation of compressor in the compressor.
(5), above-mentioned compressor lubricant oil oil mass and concentration should be not less than the required lubricating oil oil mass of compressor safe operation and the minimum of concentration.Be that cold-producing medium is when being in slumber, within the index that compressor lubricant oil oil mass after the running and concentration are positioned at design.Compressor lubricant oil oil mass and concentration can be analyzed the defective that compressor operating may exist by the difference of oil mass or concentration when being lower than required lubricating oil oil mass of compressor safe operation and concentration minimum, and with its solution.
Claims (2)
1. method for testing safe running performance of high speed vehicle air conditioner compressor is characterized in that this method adopts following step:
