According to the said temperature and humidity regulation method of the present invention, there can also be following technical characteristic：

In the above-mentioned technical solutions, it is preferable that the computational methods of the first parameter and the second parameter, specifically include：According to sending Air temperature and blasting humidity calculate air-supply water capacity and air-supply enthalpy, and return air water capacity is calculated according to return air temperature and return air humidity With return air enthalpy, target moisture content and target enthalpy are calculated according to target temperature and target humidity；First parameter is equal to air-supply enthalpy The ratio of value and the difference of the same air-supply water capacity of the difference of return air enthalpy and return air water capacity, the second parameter are equal to target enthalpy and return air The difference of enthalpy is the same as target moisture content and the ratio of the difference of return air water capacity.

In the technical scheme, corresponding water capacity and enthalpy are calculated according to the temperature and humidity of diverse location.Water capacityWherein, saturation vapor pressure P_q·bIt is the monotropic function of temperature, can checks in；For the phase measured To humidity；T is the temperature measured, and the temperature is dry-bulb temperature.Enthalpy h=1.01t+ (2500+1.84t) d.Wherein, t is to measure Temperature, the temperature is dry-bulb temperature；D is the water capacity by being calculated.According to two above formula, it is possible to according to sending Air-supply water capacity d is calculated in air temperature and blasting humidity, return air temperature and return air humidity, target temperature and target humidity_AWith Blow enthalpy h_A, return air water capacity d_BWith return air enthalpy h_B, target moisture content d_CWith target enthalpy h_C.Next, according to calculating The water capacity and enthalpy arrived, it can further calculate the first parameter and the second parameter.From the point of view of perfect condition, to ensure Interior Space Gas, which is finally reached goal-setting parameter C, target component C, can regard present air parameter B and the air-supply after air-conditioning is handled as Parameter A mixing.From conservation of mass and energy principle, there is below equation：

G_Ah_A+G_Bh_B=(G_A+G_B)h_C

G_Ad_A+G_Bd_B=(G_A+G_B)d_C

G in above formula_A、G_BRespectively parameter A and the air quality under parameter B state.Two formulas can obtain more than：

The formula of the above two is parameter state ideally, that is, under the ventilation state, the ambient parameter (phase of computer room When in return air parameter) dbjective state of setting can be reached.Two formulas set the calculating of the first parameter and the second parameter more than Method, wherein ratio of first parameter for the difference of air-supply enthalpy and return air enthalpy with air-supply water capacity and the difference of return air water capacity, I.e.Wherein the second parameter is equal to the difference of target enthalpy and return air enthalpy with the difference of target moisture content and return air water capacity Ratio, i.e.,If the first parameter is equal to the second parameter, then current state just meets the requirement of perfect condition, can be with Reach dbjective state.If the first parameter and the second parameter are simultaneously unequal, then just need according to the comparison knot under different situations Fruit, the air conditioner is controlled to be run according to different mode of operations.

In the above-mentioned technical solutions, it is preferable that control air conditioner is run according to different mode of operations, is specifically included：It is empty Device is adjusted by reducing inner blower rotating speed or improving compressor rotary speed, reduction wind pushing temperature, while air-supply water capacity is reduced, make air-conditioning Device is according to cool drying mode operation；Or air conditioner heats by opening electrical heating to air-supply, wind pushing temperature is improved, together When keep air-supply water capacity constant, make air conditioner according to etc. wet heating mode run；Or air conditioner is by opening isothermal humidification Device humidifies to air-supply, improves air-supply water capacity, while keeps wind pushing temperature constant, makes air conditioner according to isothermal humidification pattern Operation；Or air conditioner humidifies by opening equal-enthalpy humidifying device to air-supply, air-supply water capacity is improved, while keep enthalpy of blowing It is worth constant, makes air conditioner according to equal-enthalpy humidifying mode operation.

In the technical scheme, air conditioner can have multiple-working mode, wherein at least including cool drying pattern, etc. it is wet Heating mode, isothermal humidification pattern, equal-enthalpy humidifying pattern.Specifically, first, cool drying pattern typically passes through wind in reduction The methods of machine rotating speed or raising compressor rotary speed, realizes that the method by reducing inner blower rotating speed or improving compressor rotary speed can While using air conditioner cooling, to make the vapor in air be condensed at air conditioner, by the vapor in air Aqueous water discharge is changed into, realizes the effect of cool drying；Second, wait wet heating mode to be carried out by opening electrical heating to air-supply The mode of heating improves the temperature of air-supply, and it is empty not interfere with air-supply while wind pushing temperature is improved for electrically heated mode of heating The content of vapor in gas, water capacity is not influenceed, the wet mode of heating such as one kind can be considered as；3rd, isothermal humidification pattern Air-supply is humidified by way of opening isothermal humidification device, isothermal humidification device can be the humidifier of steam humidification type, The humidifier of electrode air-humidification method is such as used, because electrode humidification is that directly caused vapor is added in air, the mistake Journey does not interfere with the temperature of air, can be considered as isothermal humidification；4th, equal-enthalpy humidifying pattern is by opening the side of equal-enthalpy humidifying device Formula humidifies to air-supply, and equal-enthalpy humidifying device can be the humidifier of cold water sprays type, such as adding using wet-film humidifying method Wet device, this humidification method flash to the principle of vapor using aqueous water, absorb the heat in air and produce vapor, but During the enthalpy of air do not change, equal-enthalpy humidifying can be considered as.Above-mentioned multiple-working mode corresponds to different works respectively Make situation, air conditioner can choose different mode of operations according to different situations because every kind of mode of operation all to blow into Different adjustment is gone, so comprehensively utilizing these mode of operations, current environmental temperature effectively can be adjusted to what is needed State.

In the above-mentioned technical solutions, it is preferable that when built-in humidifier is isothermal humidification device, it is characterised in that：When first When parameter is more than the second parameter, further relatively blow water capacity and target moisture content, if air-supply water capacity is more than or equal to mesh Water capacity is marked, then starts cool drying pattern, if air-supply water capacity is less than the wet heating mode such as target moisture content, startup；When When first parameter is less than the second parameter, further compare wind pushing temperature and target temperature, if wind pushing temperature is more than or equal to target Temperature, then start cool drying pattern, if wind pushing temperature is less than target temperature, start isothermal humidification pattern.

In the technical scheme, it is proposed that the control method when air conditioner built-in humidifier is isothermal humidification device.First Judge the relation of the first parameter and the second parameter.When the first parameter is more than the second parameter, then compare air-supply water capacity and target Water capacity, it thus further determined that the specific difference of the parameters currently blown and target component.If air-supply is containing wet Amount is more than or equal to target moisture content, then should start cool drying pattern, blasting humidity is reduced using cool drying pattern. Because when blow excess moisture when, if do not reduce air-supply water capacity be unable to reach dbjective state.If air-supply is containing wet Amount is less than target moisture content, then explanation air-supply water capacity has been in a suitable state, as long as at this moment improving wind pushing temperature, It can just make the first parameter and the second parameter equal, reach perfect condition, so the wet heating mode such as operation.When the first parameter is small When the second parameter, because using isothermal humidification device in the program, wind pushing temperature will not be changed when carrying out humidification work, So first to judge whether wind pushing temperature meets the requirements, then judge whether to need to humidify.Further compare wind pushing temperature and mesh Temperature is marked, if wind pushing temperature is more than or equal to target temperature, it is necessary to first carry out other operations again to air-supply cooling, so, now Run cool drying pattern.If wind pushing temperature is less than target temperature, illustrate that current wind pushing temperature has met the requirements, only need To increase air-supply water capacity in the case of temperature-resistant, so starting isothermal humidification pattern.

In the technical scheme, it is proposed that the control method when air conditioner built-in humidifier is equal-enthalpy humidifying device.First Judge the relation of the first parameter and the second parameter.When the first parameter is more than the second parameter, then compare air-supply water capacity and target Water capacity, it thus further determined that the specific difference of the parameters currently blown and target component.If air-supply is containing wet Amount is more than or equal to target moisture content, then should start cool drying pattern, blasting humidity is reduced using cool drying pattern. Because when blow excess moisture when, if do not reduce air-supply water capacity be unable to reach dbjective state.If air-supply is containing wet Amount is less than target moisture content, then explanation air-supply water capacity has been in a suitable state, as long as at this moment improving wind pushing temperature, It can just make the first parameter and the second parameter equal, reach perfect condition, so the wet heating mode such as operation.When the first parameter is small When the second parameter, because using equal-enthalpy humidifying device in the program, air-supply enthalpy will not be changed when carrying out humidification work, So first to judge whether air-supply enthalpy meets the requirements, then judge whether to need to humidify.Further compare air-supply enthalpy and mesh Enthalpy is marked, if air-supply enthalpy is more than or equal to target enthalpy, it is necessary to first carry out other operations again to air-supply reduction enthalpy, so, Cool drying pattern is now run, cool drying pattern can reduce wind pushing temperature and air-supply water capacity, can be effectively reduced Air-supply enthalpy.If air-supply enthalpy is less than target enthalpy, illustrate that current air-supply enthalpy has met the requirements, it is only necessary in enthalpy Increase air-supply water capacity in the case of constant, so starting equal-enthalpy humidifying pattern.

As shown in figure 14, when A ' water capacities are less than C points, air-supply can be heated by electrical heating, this operational mode For etc. wet heating mode, i.e. A '-A processes.Air-supply point A ' can be adjusted by this process to set point A.

Read actual air supply parameter A ', return air parameter B and goal-setting parameter C.A ' positions are judged according to formula, whenThink A ' above BC straight lines (as shown in FIG. 15 to 18).Entered according to A ' position Row judges, for the type of air conditioner built-in humidifier, there is different Rule of judgment.

When air conditioner built-in humidifier is isothermal humidification device, such as during the electrode humidification of steam humidification type, now may be used It is isothermal humidification to be approximately considered the humidification.

As shown in figure 15, when A ' temperature is more than or equal to C points, typically compressed by adjusting to reduce inner blower rotating speed or improve The methods of machine rotating speed, realizes cool drying pattern, i.e. A '-A " process.Continue to judge whether A " temperature is more than or equal to C points, if so, Then think now to be unable to reach goal-setting operating mode, air conditioner Tip element is prompted and remained on, if it is not, then entering such as Working condition shown in Figure 16.

As shown in figure 16, when A ' temperature is less than C points, air-supply can be humidified by humidifier, this operational mode is Isothermal humidification pattern, i.e. A '-A processes.Air-supply point A ' can be adjusted by this process to set point A.
