Abstract
The present invention relates to a kind of air-conditioner fan control methods, comprising the following steps: 1) outdoor environment temperature is divided into multiple sections, outdoor heat exchanger middle of target temperature T3 is arranged；2) outdoor environment temperature T1 is detected, determines current T3；3) outdoor heat exchanger portion's temperature T2 in practice is detected；△ T=T2-T3 is calculated simultaneously；4) set temperature difference range [T4, T5]；If △ T < T4, goes to step 6)；If T4≤△ T≤T5, fan keeps current gear；If △ T > T5, goes to step 8)；6) whether detection fan is most high-grade, if so, then going to step 11)；7) fan adds 1 grade；Then, step 10) is gone to；8) whether detection fan is most to keep out, if so, then going to step 11)；9) fan subtracts 1 grade；10) after the continuous service S time, return step 2)；11) unit frequency reducing is run, and is alarmed.
Description
Technical field
The present invention relates to a kind of air conditioning control method, especially a kind of method of control air-conditioning fan operating, specifically
It is a kind of air-conditioner fan control method.
Background technique
Air-conditioning is when refrigeration (heating) is run, in order to guarantee condensation (evaporation) effect of outdoor heat exchanger.In different rings
At a temperature of border, revolving speed is slow, and condensation effect is poor, and high pressure is high, and system effectiveness is low, and revolving speed is too fast, and motor fret is big, and energy-saving effect is poor,
Therefore under different circumstance temperatures, heat exchange efficiency is not only can be improved in suitable rotation speed of fan, guarantees the ability of system, and make
The lifetime of motor, energy-saving effect are good.
In current air-conditioning products, fan is to set different fixed rotating speeds according to different circumstance temperatures.This control method cannot
Environment in changeable air-conditioning system is adapted to, causes outdoor heat exchanger degree of supercooling insufficient, unit capacity is made to be not in full use.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of air-conditioner fan control methods, can make wind
The adjusting of fan is more accurate, more matches with the operation of unit, thus, fully play the ability of unit.
The technical scheme is that
A kind of air-conditioner fan control method, comprising the following steps:
1) outdoor environment temperature is divided into multiple sections, 1 outdoor heat exchanger is arranged in corresponding each outdoor environment temperature section
Middle of target temperature T3；
2) outdoor environment temperature T1 is detected, determines current outdoor heat exchanger middle of target temperature T3；
3) outdoor heat exchanger portion's temperature T2 in practice is detected；△ T=T2-T3 is calculated simultaneously；
4) set temperature difference range [T4, T5]；If △ T < T4, goes to step 6)；If T4≤△ T≤T5, fan is kept
Current gear；If △ T > T5, goes to step 8)；
6) detection fan whether be it is most high-grade, if so, then going to step 11)；
7) fan adds 1 grade；Then, step 10) is gone to；
8) whether detection fan is most to keep out, if so, then going to step 11)；
9) fan subtracts 1 grade；
10) after the continuous service S time, return step 2)；
11) air-conditioner set frequency reducing is run, and is alarmed.
Further, the S in the step 10) is 10 seconds.
Beneficial effects of the present invention:
The present invention has rational design, and control is simple, the adjusting of fan can be made more accurate, and match closely with the operation demand of unit
It closes, thus, unit performance can be given full play to, user's impression is promoted.
Specific embodiment
Below with reference to embodiment, the present invention is further illustrated.
A kind of air-conditioner fan control method, comprising the following steps:
1) outdoor environment temperature is divided into multiple sections, 1 outdoor heat exchanger is arranged in corresponding each outdoor environment temperature section
Middle of target temperature T3；
2) outdoor environment temperature T1 is detected, determines current outdoor heat exchanger middle of target temperature T3；
3) outdoor heat exchanger portion's temperature T2 in practice is detected；△ T=T2-T3 is calculated simultaneously；
4) set temperature difference range [T4, T5]；If △ T < T4, goes to step 6)；If T4≤△ T≤T5, fan is kept
Current gear；If △ T > T5, goes to step 8)；
6) whether detection fan is most high-grade, if so, then going to step 11)；
7) fan adds 1 grade in current gear；Then, step 10) is gone to；
8) whether detection fan is most to keep out, if so, then going to step 11)；
9) fan subtracts 1 in current gear grade；
10) after continuous service 10 seconds, return step 2), start new detection cycle；
11) air-conditioner set frequency reducing is run, and is alarmed, and can be debugged by artificial detection.
Fan gear in the present embodiment is 24 grades total.When unit starting, fan is generally in 1 grade.The T1 is by setting
The temp probe being placed in beside outdoor unit obtains.The T2 is obtained by the temp probe being set in outdoor heat exchanger mid-game.
Part that the present invention does not relate to is the same as those in the prior art or can be realized by using the prior art.
