Detailed description of the invention
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The present invention proposes a kind of air-conditioner.As shown in Figure 1, this air-conditioner can comprise a processor, at least two group temperature sensors.Wherein one group of temperature sensor machine return air inlet disposed in the interior place, with the temperature T1 in sensing chamber; On another group temperature sensor machine heat exchanger pipeline disposed in the interior, to detect the pipe temperature T2 of indoor heat exchanger.Then processor receives temperature T1, temperature T2, and the Dehumidification controlling scheme pre-set according to processor, dehumidifies accordingly to air-conditioner.The present invention not only eliminates the setting of humidity sensor, and the pipe temperature T2 considering indoor temperature T1 and indoor heat exchanger due to the present invention carries out Dehumidification controlling, thus achieves effective dehumidifying.
Above-mentioned processor will preset multiple dehumidification operating mode, and often kind of dehumidification operating mode is provided with corresponding target humidity RH, controling parameters a and b.This dehumidification operating mode can be selected for user.When user selects corresponding dehumidification operating mode, processor then obtains controling parameters corresponding to user-selected dehumidification operating mode, and according to the Dehumidification controlling scheme preset, carries out corresponding Dehumidification controlling to air-conditioner.The present embodiment by providing the selection of user's dehumidification operating mode, thus make user can oneself demand and make air-conditioner indoor humidity can be controlled in suitable scope, meet the dehumidification of different user.
As shown in Figure 1, the Dehumidification controlling flow process of this processor is shown.The dehumidification control method of this air-conditioner can comprise the following steps:
Step S110, when detecting dehumidifying instruction, periodically obtain the indoor heat exchanger pipe temperature T2 of indoor environment temperature T1 and air-conditioner;
In the present embodiment, equal set temperature sensor in the return air inlet place and indoor heat exchanger coil pipe of indoor set, detects indoor environment temperature T1 and indoor heat exchanger pipe temperature T2 with correspondence.When detecting dehumidifying instruction, then can obtain the indoor environment temperature T1 detected by this temperature sensor and indoor heat exchanger pipe temperature T2.
Under step S120, acquisition target humidity, the instantaneous dew-point temperature Td corresponding with described indoor environment T1;
Obtain the instantaneous dew-point temperature Td corresponding with indoor environment temperature T1, specifically can be: in an example, in air-conditioner, pre-set corresponding dew-point temperature calculate rule, then the parameter of dew-point temperature calculating required for rule is obtained, such as indoor environment temperature, finally again according to obtained parameter, calculates rule according to dew-point temperature, calculate under obtaining target humidity, the instantaneous dew-point temperature Td corresponding with indoor environment temperature T1.In another example, can be prestored a dew-point hygrometer in air-conditioner, this dew-point hygrometer have recorded the mapping relations between target humidity, indoor environment temperature and dew-point temperature, therefore when obtaining indoor environment temperature T1, again according to the dew-point hygrometer that this prestores, table look-up under obtaining target humidity, the instantaneous dew-point temperature Td corresponding with indoor environment temperature T1.
In the present embodiment, if the non-selected target humidity of user, then this target humidity is defaulted as the humidity that air-conditioner pre-sets.
Step S130, calculate the temperature difference △ T of described indoor environment temperature T1 and indoor objects temperature Ts
1, and the temperature difference △ T between the pipe temperature T2 of instantaneous dew-point temperature Td and indoor heat exchanger
2;
Step S140, according to described temperature difference △ T
1and described temperature difference △ T
2, air-conditioner is controlled, to make described temperature difference △ T
1be positioned at default temperature range, and described temperature difference △ T
2for the initial temperature differences threshold value a preset;
Calculating temperature difference △ T
1=T1-Ts, and calculating temperature difference △ T
2=Td-T2.In the present embodiment, this temperature range preset is [-0.2 ,+0.2], even temperature difference △ T
1be positioned at the scope that this is preset, then control air-conditioner and maintain current running status; When indoor environment temperature T1 be greater than user setting indoor objects temperature Ts and temperature difference △ T
1when being positioned at outside this scope preset, then cooling being carried out to air-conditioner and control; When indoor environment temperature T1 be less than user setting indoor objects temperature Ts and temperature difference △ T
1when being positioned at outside this scope preset, then intensification being carried out to air-conditioner and control.Repeated execution of steps S110-step S140, through repeatedly adjusting, until control temperature difference △ T
1be positioned at default temperature range.Because indoor environment temperature T1 changes, then under target humidity, also there is corresponding change in the instantaneous dew-point temperature that this indoor environment temperature T1 is corresponding, therefore, and the temperature difference △ T of instantaneous dew-point temperature Td and indoor heat exchanger pipe temperature T2
2to maintain default initial temperature differences threshold value a, this initial temperature differences threshold value a arranges different values by under different air-conditioners, different humiture environment, and its concrete span can be 1 ~ 12 DEG C.
Step S150, as described temperature difference △ T
1be positioned at default temperature range, and described temperature difference △ T
2after default initial temperature differences threshold value, judge whether described indoor heat exchanger pipe temperature T2 changes and variable quantity is positioned at outside the first default domain of walker; If so, then proceed to step S170, if not, then proceed to step S160;
As described temperature difference △ T
1be positioned at default temperature range, and described temperature difference △ T
2after default initial temperature differences threshold value, represent that air-conditioner enters stable state.After air-conditioner stable operation and preset time, then judge whether described indoor heat exchanger pipe temperature T2 changes, if change, then judge whether the variable quantity of this pipe temperature T2 is positioned at the first default domain of walker.Be specially: Tube Sheet of Heat Exchanger temperature T2 in Preset Time sensing chamber, and judge whether the pipe temperature T2 of front and back twice changes, and variable quantity is 0.5.If the first domain of walker preset is [-0.5 ,+0.5], then judge that this variable quantity is in the first domain of walker preset.If variable quantity is 1, then judge that this variable quantity is outside the first domain of walker preset.
Step S160, maintenance current operating conditions;
When described indoor heat exchanger pipe temperature T2 does not change, or the variable quantity changed is positioned at the first default domain of walker, then control air-conditioner and remain on current operating conditions.
Step S170, change according to described indoor heat exchanger pipe temperature T2, control the operation of air-conditioner, maintain in the first default domain of walker to make the variable quantity of described indoor heat exchanger pipe temperature T2.
When described indoor heat exchanger pipe temperature T2 changes, and variable quantity is positioned at outside the first default domain of walker, then according to the change of indoor heat exchanger pipe temperature T2, control the operation of air-conditioner, such as, when indoor heat exchanger pipe temperature T2 rises, increase indoor air velocity, or reduce compressor operating frequency, or reduce system throttles etc., maintain in the first default domain of walker to make the variable quantity of described indoor heat exchanger pipe temperature T2.
The embodiment of the present invention, when air-conditioner dehumidifies, by obtaining indoor environment temperature T1 and indoor heat exchanger pipe temperature T2, and calculates the temperature difference △ T between indoor environment temperature T1 and indoor objects temperature Ts
1and the temperature difference △ T between instantaneous dew-point temperature Td and indoor heat exchanger pipe temperature T2
2, then according to described temperature difference △ T
1with temperature difference △ T
2air-conditioner is controlled.And, in the Dehumidification controlling process of air-conditioner, also whether changed, if change by monitoring indoor environment temperature T1 and indoor heat exchanger pipe temperature T2, then air-conditioner is controlled, remain unchanged to make indoor environment temperature T1 and indoor heat exchanger pipe temperature T2.Therefore, the embodiment of the present invention does not need the control that can be realized indoor humidity by humidity sensor, but also indoor humidity can be made accurately to reach target humidity.
Further, above-mentioned steps S170 specifically comprises:
When the pipe temperature T2 of indoor heat exchanger declines, the temperature difference T between the pipe temperature T2 of control room internal object temperature Ts and described dew-point temperature Td and indoor heat exchanger
2for: Δ T
2=a-n*b;
When the pipe temperature T2 of indoor heat exchanger rises, the temperature difference T between the pipe temperature T2 of control room internal object temperature Ts and described dew-point temperature Td and indoor heat exchanger
2for: Δ T
2=a+n*b; Wherein, a and b is default reference constant, and n is for regulating number of times.
When the pipe temperature T2 of indoor heat exchanger changes, judge that this pipe temperature T2 declines or rises according to variable quantity.Drop to example with the pipe temperature T2 of indoor heat exchanger, the adjustment process that the pipe temperature T2 of indoor heat exchanger rises is implemented with reference to it.When the pipe temperature T2 of indoor heat exchanger declines, then temperature difference T will be made
2for a-b, namely make the pipe temperature T2 of indoor heat exchanger be Td-a+b, therefore according to the pipe temperature T2 of this indoor heat exchanger, air-conditioner is controlled.First time if the pipe temperature T2 of indoor heat exchanger still declines, then will make temperature difference T after controlling
2for a-2*b, namely make the pipe temperature T2 of indoor heat exchanger be Td-a+2*b, therefore according to the pipe temperature T2 of this indoor heat exchanger, air-conditioner is controlled.The like, until the variable quantity of described indoor heat exchanger pipe temperature T2 maintains in the first default domain of walker.When after controlling, when the variable quantity of described indoor heat exchanger pipe temperature T2 maintains in the first default domain of walker, then n is reset.
The embodiment of the present invention is based on indoor environment temperature T1, indoor heat exchanger pipe temperature T2, indoor objects temperature Ts, instantaneous dew-point temperature Td and reference constant a, b, automatically the running frequency of compressor, the delivery temperature of compressor and rotation speed of fan etc. can be regulated, thus realize dehumidification process can relative humidity effectively in control room, and then improve air conditioning comfortableness.
Further, as shown in Figure 2, also comprise after above-mentioned steps S170:
Step S180, judge whether indoor environment temperature T1 changes and variable quantity is positioned at outside the second default domain of walker; If so, then step S190 is proceeded to; If not, then step S160 is proceeded to;
When the change according to described indoor heat exchanger pipe temperature T2, after controlling the operation of air-conditioner, by judging whether indoor environment temperature T1 changes, if change, then judge whether the variable quantity of this pipe temperature T2 is positioned at the second default domain of walker.Be specially: detect indoor environment temperature T1 every Preset Time, and judge whether the indoor environment temperature T1 of front and back twice changes, and variable quantity is 0.5.If the second domain of walker preset is [-0.5 ,+0.5], then judge that this variable quantity is in the second domain of walker preset.If variable quantity is 1, then judge that this variable quantity is outside the second domain of walker preset.
Step S180, air-conditioner to be controlled, to make the variable quantity of described indoor environment temperature T1 maintain in the second default domain of walker, and described temperature difference △ T
2maintain current state.
When described indoor heat exchanger T1 does not change, or the variable quantity changed is positioned at the second default domain of walker, then control air-conditioner and remain on current operating conditions.When described indoor environment temperature T1 changes, and variable quantity is positioned at outside the second default domain of walker, then according to the change of indoor environment temperature T1, control the operation of air-conditioner, maintain in the second default domain of walker to make the variable quantity of described indoor environment temperature T1.Based on the change of indoor environment temperature T1 to the control of air-conditioner, the existing control program of air-conditioner can be adopted, just repeat no more at this.
In order to the Dehumidification controlling scheme of above-mentioned air-conditioner can be described better, below specific explanations will be carried out by 3 examples.
Example one
During air-conditioner start, the indoor objects temperature Ts of user's setting is 24 DEG C, and user-selected air-conditioner dehumidification operating mode is M1, and target humidity corresponding to operational mode M1 is 60%, a=5 DEG C, b=1.The indoor environment temperature T1=30 DEG C of current air-conditioner, relative humidity is 70%.After air-conditioner start, first air-conditioner according to T1=30 DEG C and relative humidity 60%, calculates existing dew point temperature Td=23.9 DEG C.Because current indoor environment temperature T1 is higher than indoor objects temperature Ts, therefore air-conditioner carries out cool-down dehumidification, i.e. refrigeration mode routinely, to control the temperature difference of indoor environment temperature T1 and indoor objects temperature Ts in the first temperature range preset, control the temperature difference △ T of the pipe temperature T2 of existing dew point temperature Ts and indoor heat exchanger simultaneously
2=Td-T2 is (when such as temperature difference control is 5 DEG C, then T2=18.9 DEG C) in the second temperature range preset.Due to after indoor environment temperature T1 declines, dew-point temperature Td will follow decline, △ T
2, indoor heat exchanger pipe temperature T2 also synchronous adjustment.After said process adjusts repeatedly, such as, by controlling the temperature difference of indoor environment temperature T1 and indoor objects temperature Ts in the first temperature range preset, T1=TS=24 DEG C, dew-point temperature Td=18.7 DEG C now, if ensure △ T
2=Td-T2=5 DEG C, then the pipe temperature T2=13.7 DEG C of indoor heat exchanger.
As the temperature difference T of indoor environment temperature T1 and described indoor objects temperature Ts
1remain in the first default temperature range, and after continuing a preset time, will judge whether the pipe temperature T2 of indoor heat exchanger changes.When the pipe temperature T2 of indoor heat exchanger remains unchanged, control air-conditioner and maintain current operating conditions; When the pipe temperature T2 of indoor heat exchanger changes, such as, when the pipe temperature T2 of indoor heat exchanger rises, then control △ T
2=Td-T2=a+b=6 DEG C, i.e. T2=12.7 DEG C.Deterministic process is above repeated again, if the temperature difference △ T of indoor environment temperature T1 and indoor objects temperature Ts after a period of time
1in the first temperature range preset, and when the pipe temperature T2 of indoor heat exchanger still rises, then control △ T
2=Td-T2=a+2b=7 DEG C, i.e. T2=11.7 DEG C.Deterministic process is above repeated again, if the temperature difference △ T of indoor environment temperature T1 and indoor objects temperature Ts after a period of time
1in the first temperature range preset, and when the pipe temperature T2 of indoor heat exchanger still rises, then control △ T
2=Td-T2=a+3b=8 DEG C, i.e. T2=10.7 DEG C.After said process adjusts repeatedly, the temperature difference △ T of indoor environment temperature T1 and indoor objects temperature Ts will be controlled
1in the first temperature range preset, the pipe temperature T2 controlling indoor heat exchanger remains unchanged.
Example two
During air-conditioner start, the indoor objects temperature Ts of user's setting is 24 DEG C, and user-selected air-conditioner dehumidification operating mode is M1, and target humidity corresponding to operational mode M1 is 60%, a=5 DEG C, b=1.The indoor environment temperature T1=30 DEG C of current air-conditioner, relative humidity is 70%.After air-conditioner start, first air-conditioner according to T1=30 DEG C and relative humidity 60%, calculates existing dew point temperature Td=23.9 DEG C.Because current indoor environment temperature T1 is higher than indoor objects temperature Ts, therefore air-conditioner carries out cool-down dehumidification, i.e. refrigeration mode routinely, to control the temperature difference of indoor environment temperature T1 and indoor objects temperature Ts in the first temperature range preset, control the temperature difference △ T of the pipe temperature T2 of existing dew point temperature Ts and indoor heat exchanger simultaneously
2=Td-T2 is (when such as temperature difference control is 5 DEG C, then T2=18.9 DEG C) in the second temperature range preset.Due to after indoor environment temperature T1 declines, dew-point temperature Td will follow decline, △ T
2, indoor heat exchanger pipe temperature T2 also synchronous adjustment.After said process adjusts repeatedly, by controlling the temperature difference of indoor environment temperature T1 and indoor objects temperature Ts in the first temperature range preset, control the temperature difference △ T of the pipe temperature T2 of existing dew point temperature Ts and indoor heat exchanger simultaneously
2=Td-T2 is in the second temperature range preset.Such as T1=TS=24 DEG C, dew-point temperature Td=18.7 DEG C now, if ensure △ T
2=Td-T2=5 DEG C, then the pipe temperature T2=13.7 DEG C of indoor heat exchanger.
As the temperature difference T of indoor environment temperature T1 and described indoor objects temperature Ts
1remain in the first default temperature range, and after continuing a preset time, will judge whether the pipe temperature T2 of indoor heat exchanger changes.When the pipe temperature T2 of indoor heat exchanger does not change, control air-conditioner and maintain current operating conditions; When the pipe temperature T2 of indoor heat exchanger changes, such as, when the pipe temperature T2 of indoor heat exchanger declines, then control △ T
2=Td-T2=a-b=4 DEG C, i.e. T2=14.7 DEG C.Deterministic process is above repeated again, if the temperature difference △ T of indoor environment temperature T1 and indoor objects temperature Ts after a period of time
1in the first temperature range preset, and when the pipe temperature T2 of indoor heat exchanger still declines, then control △ T
2=Td-T2=a-2b=3 DEG C, i.e. T2=15.7 DEG C.Deterministic process is above repeated again, if the temperature difference △ T of indoor environment temperature T1 and indoor objects temperature Ts after a period of time
1in the first temperature range preset, and when the pipe temperature T2 of indoor heat exchanger still declines, then control △ T
