Table 1 is crossed to understand, it is necessary to which the current frequency F for controlling compressor operating is 60Hz.Each value in upper table 1 can be according to specific circumstances
And flexibly set, do not limit the present invention.Determine temperature difference Tf, temperature difference TCAfterwards, then compressor operating can be determined according to upper table 1
Current frequency.
Further, in order to pass through temperature difference Tf, temperature difference TCThe wind speed that can rationally control indoor fan to run, respectively
By temperature difference TfWith temperature difference TCIt is divided into four temperature difference intervals, and the wind speed formation mapping relations run with indoor fan.As schemed
Shown in 9, wind speed determining module 400 includes in above-mentioned air conditioner constant temperature dehumidification control device:
Temperature difference TfInterval determination unit 410, for by the temperature difference TfWith the progress of default first temperature difference interval
Match somebody with somebody, determine the temperature difference TfThe temperature difference at place is interval;
Temperature difference TCInterval determination unit 420, for by the temperature difference TCWith the progress of default second temperature difference interval
Match somebody with somebody, determine the Δ TCThe temperature difference at place is interval;
Wind speed determining unit 430, for according to first temperature difference is interval, second temperature difference it is interval with indoor fan wind
The mapping relations of speed, will be with the temperature difference TfThe temperature difference at place is interval, the Δ TCThe interval corresponding wind speed of the temperature difference at place is true
It is set to the current wind speed of indoor fan operation.
By detecting indoor environment temperature T1With outdoor environment temperature T4, obtain indoor environment temperature T1With outdoor environment temperature
Spend T4Temperature difference Tf=T4-T1Afterwards, by temperature difference TfMatched with default first temperature difference interval, determine the temperature difference Tf
The temperature difference at place is interval;Obtain indoor environment temperature T1With indoor target temperature TSTemperature difference TC=T1-TS, by temperature difference TCWith
Default second temperature difference interval is matched, and determines Δ TCThe temperature difference at place is interval.It should be noted that first temperature difference is interval
For by temperature difference TfIt is divided into Δ Tf2 DEG C of <, 2 DEG C≤Δ Tf4 DEG C of <, 4 DEG C≤Δ Tf6 DEG C of <, 6 DEG C≤Δ TfFour of 8 DEG C of <
The temperature difference is interval;Second temperature difference interval is by temperature difference TCIt is divided into Δ TC2 DEG C of <, 2 DEG C≤Δ TC4 DEG C of <, 4 DEG C≤Δ TC< 6
℃、ΔTC>=6 DEG C of four temperature difference intervals.Reflected according to first temperature difference interval, second temperature difference interval with compressor operating frequency
Relation is penetrated, will be with temperature difference TfThe temperature difference at place is interval, Δ TCThe interval corresponding wind speed of the temperature difference at place is defined as indoor fan fortune
Capable current wind speed.
In the present embodiment, temperature difference Tf, temperature difference TCMapping relations between the current wind speed V run with indoor fan
As shown in table 2:
The temperature difference T of table 2f, temperature difference TCThe current wind speed V run with indoor fan mapping relations
From upper table 2, each temperature difference TfInterval and temperature difference TCInterval Corresponding matching has a wind speed V, in interval Δ
TCIn 2 DEG C of <, the current wind speed V of indoor fan operation is not by temperature difference TfInfluence, and maintain 1% wind speed it is constant;In interval
ΔTfIn 2 DEG C of <, the current wind speed V of indoor fan operation is not by temperature difference TCInfluence, and maintain 1% wind speed it is constant.Can be with
Understand, the interval division and each value in above-mentioned table 2 can be set as the case may be and flexibly, not limit the present invention.
According to temperature difference Tf, temperature difference TCMapping relations between the wind speed run with indoor fan obtain indoor fan fortune
Capable current wind speed V, the indoor fan of control air conditioner runs wind speed in this prior.For example, the indoor objects temperature that user is set
Spend for 24 DEG C, the indoor environment temperature that indoor temperature transmitter is detected is 26 DEG C, the outdoor that outdoor temperature sensor is detected
Environment temperature is 30 DEG C, then obtains the temperature difference T of indoor environment temperature and outdoor environment temperaturefFor 4 DEG C, with interval 4 DEG C≤Δ Tf
6 DEG C of matchings of <;The temperature difference T of indoor environment temperature and indoor target temperatureCFor 2 DEG C, with interval 2 DEG C≤Δ TC4 DEG C of matchings of <;
Understood by table 2, it is necessary to which the current wind speed V for controlling indoor fan to run is 10%.Each value in upper table 2 can be according to specific
Situation and flexibly set, limit the present invention.Determine temperature difference Tf, temperature difference TCAfterwards, then can be according to upper table 2, it is determined that indoor wind
The current wind speed of machine operation.
Further, as shown in Figure 10, a kind of air conditioner constant temperature dehumidification control device second embodiment of the invention is proposed.Base
In above-described embodiment, the air conditioner constant temperature dehumidification control device of the embodiment also includes:
Loop detection module 600, after the preset time of air conditioner continuous service second, detection indoor environment temperature and room
External environment temperature, and obtain the temperature difference of indoor environment temperature and outdoor environment temperature, and indoor environment temperature and indoor objects
The temperature difference of temperature.
According to the current wind speed for current frequency and the indoor fan operation for determining compressor operating, control air conditioner operation;
In order that air conditioner stable operation it is determined that compressor operating current frequency and indoor fan operation current wind speed, meanwhile,
The frequency of the compressor operating of control air conditioner and the wind speed of indoor fan operation are monitored and adjusted in real time;Air conditioner needs to continue
Run after the second preset time, then indoor environment temperature is detected by indoor temperature transmitter, and pass through outdoor temperature sensor
Outdoor environment temperature is detected, the temperature difference T of indoor environment temperature and outdoor environment temperature is obtainedf, and indoor environment temperature with
The temperature difference T of indoor target temperatureCCirculation performs above-mentioned steps S20 to step S60.Second preset time is preferably 2 minutes,
It can also flexibly set according to actual needs, not do further limitation herein.
The preferred embodiments of the present invention are these are only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
