Air conditioning is one of the commonly used household appliances, with the function of cooling and heating. As summer approaches, with the gradual increase in the use of air conditioners, some products will experience cooling attenuation after a period of use. The cooling effect is not good, generally caused by the lack of fluorine, then how to add fluoride to the air conditioner ? Next, the decoration of the home network Xiaobian to introduce the air conditioning and fluoride operation method and the basis of air conditioning and fluoride determination.
First, air conditioning and fluoride operation method
1. Turn on the air conditioner;
In the summer, when the fluorine is added, the air conditioner can be directly operated in the cooling mode. Because the fluorine-adding operation cannot be performed in the heating state, when the fluorine is added in the winter, the method of heating and reversing the valve line is used to force the air conditioner to enter the cooling state.
2. Connect the fluoride equipment;
After the air conditioner is started normally, the fluorine-added equipment is connected from the process port on the low-pressure valve side of the outdoor unit. The air and dirt in the fluoride tube must be drained during this process.
3. Pressure measurement and fluoride;
Observe the low pressure in summer, when the ambient temperature is about 32 degrees Celsius, the pressure is controlled at about 0.45MP;
In the winter, the high pressure during heating is observed, and after the pressure is stabilized, it is controlled at about 1.7 MP.
4. Remove the fluorine-added equipment;
In the state of smashing, the fluorine-added equipment is removed, and the external machine is sealed. If the equipment is heated down, a large amount of fluorinated leakage will be caused.
5. Adding fluoride is completed.
For air conditioners suspected of having leaks, check with detergent foam.
Second, the basis for the determination of air conditioning and fluoride
1. Observation method: When using the observation method for judgment, the air conditioner should first be set in the high-speed operation state of cooling or heating. When the air-conditioning refrigerant is sufficient, the temperature difference between the indoor unit exchanger and the air outlet should be: refrigeration The temperature difference is greater than 12 ° C in the state, and the temperature difference is greater than 16 ° C in the heating state. During cooling, the indoor heat exchanger condensation sounds even and low, while the outdoor shut-off valve is dew condensation, the summer condensation dripping continuously, and the connection between the indoor heat exchanger and the capillary is frost or dew.
2, measuring current: the air conditioning is adjusted in the high-speed operation of refrigeration and heating, at the low-pressure stop valve, while adding fluoride, while observing its current meter changes, when its current is close to the rated current of the air conditioner, close Fluorine bottle valve. After that, let the air conditioner continue to operate for a certain period of time. In the air conditioning and cooling state, the room temperature is close to 27 ° C or the room temperature is close to 20 ° C in the heating state, and the amount of fluorine is finely adjusted in consideration of factors such as the outdoor air temperature and the power grid. The rated current value.
3. Quantitative fluorination: Connect the three-way valve, pressure gauge, fluorinated hose, etc. in the process port of the three-way stop valve, wait until the fluorine is pumped out, start to slowly add fluorine, and use the accurate measuring tools such as platform scale to weigh. When the amount of refrigerant reduction in the fluorine bottle is equal to the standard amount specified on the nameplate, close the fluorine bottle valve.
Through the above introduction, we must be the basis for the air conditioning and fluoride operation method and air conditioning fluoride. Have a certain understanding. If you want to know more about air conditioning and fluoride, please continue to pay attention to the decoration home network.

Conference Interactive Whiteboard
As
a conference all-in-one machine, conference Interactive Whiteboard, microphones
and conference software. The small size contains great momentum, providing
high-quality pictures and sound effects for team video conferences.
In terms of camera hardware configuration, the
electronic Interactive Digital Board uses a 12 million pixel camera and
supports a wide viewing angle of 120 degree. It can be used in small and
medium-sized office spaces and can incorporate more team members into the video
conference scene. 4K high-definition resolution can provide high-quality video
images, adding points to the corporate image.
In terms of sound experience, interactive digital
board has built-in 6 array microphones to bring high-fidelity sound quality,
and conference interactive smart board can achieve up to 8 meters of remote
sound pickup, and can perform accurate sound in every corner of the meeting
room. At the same time, in the remote meeting mode, the tablet will locate the
sound source so that the speaker will not be able to display the picture, automatically gain the voice, eliminate echo and noise, even if the speaker is
far away, the audience can still hear it.
