The minimum value of Ii, if so, lack of fluorine of air-conditioners.Setting time herein can be arranged according to the actual situation.
Preferably, it is checked for convenience of installation personnel and user, it, will be in selected type Ai in step 1.1 after selection type
All corresponding connection length of tube of ambient temperature Ti and normal air-conditioning current value Ii are shown, are detected in step 2
Current air-conditioning current value I also shows out.
The invention also provides a kind of lack of fluorine of air-conditioners detection devices, use above-mentioned lack of fluorine of air-conditioners detection method to detect empty
It adjusts and whether lacks fluorine.
Wherein, lack of fluorine of air-conditioners detection device includes: control chip, obtains module and display, and control chip is stored with pre-
The mapping table first formulated obtains the temperature detector, defeated for installation personnel that module includes detection environment nowadays temperature T
Enter the input unit of current connection length of tube, the current detector of the current air-conditioning current value I of detection, control chip receives currently
When ambient temperature T, the type Ai where environment nowadays temperature T is selected according to mapping table, by selected type
All corresponding connection length of tube of ambient temperature Ti and normal air-conditioning current value Ii are sent to display and are shown in Ai,
Current air-conditioning current value I display is sent to simultaneously to show, it is normal empty further according to the current connection length of tube selection received
Current value Ii is adjusted, current air-conditioning current value I and normal air-conditioning current value Ii is compared, judges whether air-conditioning lacks fluorine.
In certain practice, the acquisition module in lack of fluorine of air-conditioners detection device can only obtain ambient temperature T and sky
Current value I is adjusted to select environment nowadays temperature according to mapping table when control chip receives environment nowadays temperature T
The type Ai where T is spent, by all corresponding connection length of tube of ambient temperature Ti and normal air-conditioning in selected type Ai
Current value Ii is sent to display and is shown, while current air-conditioning current value I is sent to display and is shown.Installation personnel exists
