The specific embodiment
The invention discloses a kind of acquisition methods of cross valve startup value, the application being worth by cross valve startup, avoided cross valve within it portion be full of under the state of liquid refrigerants and start, improved the service life of cross valve.The present invention also provides a kind of acquisition device of cross valve startup value and the air-conditioning that application has above-mentioned cross valve startup value.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 2, the schematic flow sheet of the acquisition methods of the cross valve startup value that Fig. 2 provides for the embodiment of the present invention.
As shown in Figure 2, the embodiment of the present invention provides a kind of acquisition methods of cross valve startup value, comprises step:
S1: start compressor;
Open the compressor of air-conditioning.
S2: the refrigerant state of observing the entrance point of cross valve;
At the entrance point of cross valve, observe the state of the refrigerant that flows into cross valve, because compressor is opened, the refrigerant that flows into cross valve is liquid refrigerants.
S3: duration when detection liquid refrigerants has been flowed by entrance point and/or the operating mode of entrance point, and as cross valve startup value;
After detecting liquid refrigerants and being opened by compressor to the entrance point by cross valve flow duration of process, and/or, the operating mode of entrance point when detection liquid refrigerants has been flowed by entrance point.And the operating mode of entrance point can be for one in the pressure and temperature in entrance point etc. or all.And using the operating mode of duration or entrance point as cross valve startup value.Wherein, in duration when cross valve startup value can have been flowed by entrance point for liquid refrigerants or the operating mode of entrance point one, can be also the total data of the operating mode of duration and entrance point.

In the 4th kind of embodiment, step S3 is specially: duration when detection liquid refrigerants has been flowed by entrance point and the operating mode of entrance point, and as cross valve startup value.The temperature value of entrance point when the force value of entrance point and liquid refrigerants have been flowed by entrance point when duration, liquid refrigerants when detection has been flowed by entrance point to liquid refrigerants by compressor start flowed by entrance point, and be applied in air-conditioning, when three's condition all meets, cross valve starts to start and complete conversion.Further avoided the liquid hit phenomenon in cross valve transfer process.
Any two kinds when while also can duration, liquid refrigerants when having been flowed by entrance point to liquid refrigerants by compressor start having been flowed by entrance point, the force value of entrance point and liquid refrigerants have been flowed by entrance point in the temperature value of entrance point are worth as cross valve startup, and all can reach above-mentioned effect, at this, introduce no longer one by one.
The embodiment of the present invention also provides a kind of acquisition device of cross valve startup value, comprising: for being arranged on the liquid checkout gear of the entrance point of cross valve; With the communication connection of liquid checkout gear, the logger of the cross valve startup value while having been flowed by entrance point for recording liquid refrigerants, cross valve startup value is the duration of liquid refrigerants while having been flowed by entrance point and/or the operating mode of entrance point.
Acquisition device by cross valve startup value that the embodiment of the present invention is provided is applied in air-conditioning to be detected, measure the cross valve startup value of this air-conditioning, and complete the commutation of cross valve while making cross valve in air-conditioning reach cross valve startup value, the situation of effectively having avoided having a large amount of liquid refrigerants in cross valve and damaged by refrigerant liquid hammer, the service life of having improved cross valve.
Further, also comprise that environmental detection set is connected with recorder communication for obtaining the environmental detection set of environmental information.Also can, using the master control borad of air-conditioning to be measured and corresponding temperature-detecting device as environmental detection set, by air-conditioning direct-detection, go out environmental information.
In the first embodiment, liquid checkout gear is liquid-sighting glass; The time regulator of duration when logger has been flowed by entrance point to liquid refrigerants by compressor start for record.By liquid-sighting glass direct-detection, go out the duration, be recorded in time regulator.
