Description of the drawings
Fig. 1 is the structural schematic diagram of the air-conditioner outdoor unit detecting system of the present invention.
Specific implementation mode
To keep the embodiment of the present invention, technical solution and advantage more obvious, below in conjunction with attached drawing to the skill of the present invention
Art scheme is clearly and completely described, it is clear that and the embodiment described is a part of the embodiment of the present invention, rather than all
Embodiment.It will be apparent to a skilled person that these embodiments are used only for explaining the technical principle of the present invention, and
It is not intended to be limiting protection scope of the present invention.
Referring to Fig.1, Fig. 1 is the structural schematic diagram of the air-conditioner outdoor unit detecting system of the present invention.As shown in Figure 1, of the invention
Detecting system include standard indoor unit 1, be connected with medium circulation pipeline between standard indoor unit 1 and air-conditioner outdoor unit to be measured
2.That is, after outdoor unit to be measured enters detection production line, formed by medium circulation pipeline 2 between standard indoor unit 1
Refrigerant circulation circuit heats/freezes test for being carried out to outdoor unit to be measured.The present invention detecting system further include：Pressure is examined
Survey device 3 and control device 4.Wherein, pressure-detecting device 3 is used for the pressure of examination criteria indoor unit 1；When to air-conditioning to be measured
Outdoor unit carries out after heating/freezing test, when the pressure for the standard indoor unit 1 that pressure-detecting device 3 detects reaches setting
When pressure, control device 4 can control the disconnection of medium circulation pipeline 2；Wherein, setting pressure is more than standard atmospheric pressure, to protect
The pressure of card standard indoor unit 1 is positive pressure, realizes the purpose of positive pressure getter.So, since the pressure of standard indoor unit 1 is
Positive pressure, even if storing micro- leakage, outside air will not enter standard indoor unit 1, and to effectively prevent, detecting system is mixed to go
The phenomenon that air.
It should be noted that above-mentioned setting pressure can carry out self-defined setting according to actual conditions by operating personnel,
As long as being theoretically higher than external atmosphere pressure.In the present embodiment, setting pressure is illustrated by taking 0.2Mpa as an example.
As an example, several solenoid valves (solenoid valve is not shown in Fig. 1) are provided in medium circulation pipeline 2, control dress
The opening and closing of solenoid valve can be controlled to open/disconnect medium circulation pipeline 2 by setting 4.Specifically, when outdoor unit to be measured enters detection
After production line is ready, control device 4 controls corresponding solenoid valve and opens, to carry out heating/freezing survey to standard outdoor machine
Examination.After carrying out heating/freezing test to air-conditioner outdoor unit to be measured, the pressure of 3 examination criteria indoor unit 1 of pressure-detecting device
Power, when the pressure detected reaches 0.2Mpa, control device 4 controls corresponding solenoid valve and closes, and keeps medium circulation pipeline 2 disconnected
It opens, the pressure of standard indoor unit 1 is locked in 0.2Mpa, delay controls plug and is detached from outdoor unit to be measured, completion pair again after several seconds
The detection of outdoor unit to be measured, the outdoor unit to be measured enter downstream.
Preferably, solenoid valve of the invention is two-way fluid stopping solenoid valve.Further, impurity enters two-way fluid stopping in order to prevent
Solenoid valve installs filter screen (being to show in Fig. 1), the refrigerant warp in medium circulation pipeline 2 at two-way fluid stopping electromagnetic valve entrance
It crosses after the filter screen again by with two-way fluid stopping solenoid valve, having ensured the cleanliness factor in two-way fluid stopping solenoid valve.
With continued reference to Fig. 1, detecting system of the invention further includes display screen 5, and display screen 5 is for showing that pressure detecting fills
Set the pressure and setting pressure that 3 detect.Specifically, in the present embodiment, display screen 5 is touch screen, touch screen connection control dress
4 are set, startupoptions is set on touch screen.Then operating personnel can pass through startup by the self-defined setting pressure of the touch screen
Option starts the detecting system.That is, touch screen is equivalent to human-computer interaction circle between detecting system and operating personnel
Face, operating personnel control detecting system by touch screen and work.
As preferred embodiment, detecting system of the invention further includes pressure gauge 6, and pressure gauge 6 is for detecting and showing
The pressure of the quasi- indoor unit of indicating 1, to which the pressure initiation shown with display screen 5 is mutually examined, further improve detecting system can
By property.
As preferred embodiment, detecting system of the invention further includes warning device 6.It is waited for when detecting system is in
When machine state, i.e., standard indoor unit 1 is not connected with outdoor unit to be measured at this time, if the standard that pressure-detecting device 3 detects
The current pressure of indoor unit less than setting pressure, and set pressure subtract current pressure more than preset value when, warning device 6 is sent out
Alarm sounds.That is, in the state that detecting system is in standby, if the pressure of standard indoor unit 1 is less than
After 0.2Mpa a certain ranges, illustrate detecting system exist leakage the case where, by alarm sounds operating personnel to detecting system into
Row detection, searches dew point in time, the station off-time is reduced, to improve production efficiency.
As a preferred embodiment, the present invention when testing outdoor unit to be measured, first carries out heating test,
Refrigeration test is carried out again, in the test process that freezes, when detecting that the pressure of standard indoor unit 1 reaches 0.2Mpa, control dress
It sets the corresponding solenoid valve of 4 controls to close, delay will control plug for several seconds and be detached from outdoor unit to be measured again, complete to outdoor unit to be measured
Detection, while the pressure in standard indoor unit 1 is locked in setting pressure.
In conclusion pressure of the present invention by examination criteria indoor unit, and reach setting in the pressure of standard indoor unit
When being worth (such as 0.2Mpa), medium circulation pipeline is closed, terminates test, ensures that the pressure of standard indoor unit is positive pressure, to realize
The purpose of positive pressure getter.Beneficial effects of the present invention are as follows：It analyzes, can fundamentally prevent in detecting system from technological angle
In run into air, also eliminating in detecting system secondary refrigerant leakage influences product quality；From global analysis, not only avoid because of inspection
High repair rate, also improves productive temp to a certain extent caused by examining system is bad；It is analyzed from technological layer, it will be original
Human body sense of touch is improved to pressure difference analysis alarm, shows more intuitive by detecting system leakage.The present invention is replacing original technique
Under the conditions of, so that detecting system is more improved and without any hidden danger.
So far, it has been combined preferred embodiment shown in the drawings and describes technical scheme of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific implementation modes.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make the relevant technologies feature equivalent change or replacement, these
Technical solution after change or replacement is fallen within protection scope of the present invention.
