Outdoor environment temperature is not detected in the embodiment of the present invention, but directly detects drive energy valve opening, because driving
Energy source valve opening can truly reflect the load of air conditioning area, be automatically adjusted according to the drive energy valve opening of detection
The outlet target temperature of air-conditioner set.It should be noted that refrigeration air-conditioning unit is identical with the control principle of cooling/heating air conditioner unit,
It is introduced separately below, introduces the temprature control method of refrigeration air-conditioning unit first.
Embodiment of the method one：
Referring to Fig. 1, the figure is the flow chart of embodiment of the method one that air-conditioner set provided by the invention automatically adjusts temperature.
The method that the air-conditioner set that the present embodiment provides automatically adjusts temperature, applied to refrigeration air-conditioning unit, including：
S101：Detect the average aperture SV of the drive energy valve of the refrigeration air-conditioning unit in the given time0And institute
State the current cooling water outlet target temperature of refrigeration air-conditioning unit；
For example, current cooling water outlet target temperature is 16 degrees Celsius.
S102：By the average aperture SV0Setting aperture corresponding with the current cooling water outlet target temperature makes the difference
Obtain the first difference；Multiple setting aperture SV are set in the control panel of the refrigeration air-conditioning uniti；One setting aperture SVi
A corresponding cooling water outlet target temperature Ti；I=1 ... n, wherein n are the integer value of setting；
It should be noted that aperture is set to be multiple in control panel, such as：SV1、SV2、SV3SVn。
Cooling water outlet target temperature corresponding to different setting apertures is different, for example, SV1Corresponding cooling water outlet mesh
It is T to mark temperature1, SV2Corresponding cooling water outlet target temperature is T2, SV3Corresponding cooling water outlet target temperature is T3, SVnIt is corresponding
Cooling water outlet target temperature be Tn。
For example, aperture is set corresponding to 16 degrees Celsius as 20%, then by SV0Made the difference with 20% and obtain the first difference.
S103：If the absolute value of first difference is less than or equal to the first predetermined threshold delta SVi, then remain described and work as
Preceding cooling water outlet target temperature；
It is understood that the absolute value of the first difference is less than or equal to the first predetermined threshold, then driving need not be adjusted
Energy valve opening, keep current aperture and current cooling water outlet target temperature.
S104：If the absolute value of first difference is more than the Δ SVi, then the cold of the refrigeration air-conditioning unit is adjusted
Water out target temperature is to Tk, the TkCorresponding SVkIt is apart from the SV0A nearest SVi。
It is understood that when the absolute value of the first difference is more than the first predetermined threshold, current cooling water outlet is represented
Target temperature is unsatisfactory for the cooling load of client's air conditioning area, it is necessary to which cooling water outlet target temperature is adjusted, the side of regulation
Formula is by finding cooling water outlet target temperature corresponding with the closest setting aperture of aperture that is averaged.So, system can be made
Cold air-conditioner set is more energy efficient.
In order that those skilled in the art are more clearly understood that the technical scheme of above example introduction, with reference to table 1
It is further detailed.
Table 1
From table 1 it follows that SV0For 22.0%, it is assumed that current cooling water outlet target temperature is 16, then 16 degree correspond to
Setting start as 20%.Therefore, SV0It is 2% with 20% the first difference made the difference<ΔSVi=2.5%；Therefore, keep current
Cold water outlet temperature it is constant, that is, continue as 16 degrees Celsius.
It is understood that the drive energy valve opening for assuming detection is not 22.0%, but 24.0%.Now
24.0% corresponding with 16 degree sets the first difference that aperture 20% makes the difference as 4%.Due to 4%>ΔSVi=2.5%；Therefore,
Need to adjust cooling water outlet target temperature, as it can be seen from table 1 setting aperture 25% and the distance of average aperture 24.0% of detection
Recently, therefore, that the outlet target temperature of refrigeration air-conditioning unit is adjusted into cooling water outlet target temperature 14 corresponding to 25% is Celsius
Degree.Because therefore the drive energy valve opening of detection, it is Celsius can to remain running in 16 with the load of actual response air conditioning area
Degree has not met the requirement of air conditioning area load, and the cooling water outlet target temperature after regulation can meet air conditioning area load
Requirement under, make air-conditioner set more energy efficient.
The method that the present embodiment provides, detects the drive energy valve opening of refrigeration air-conditioning unit and current cooling water outlet
Target temperature, drive energy valve opening setting aperture corresponding with current cooling water outlet target temperature is made the difference, such as
The absolute value of fruit difference is more than the first predetermined threshold, then needs to adjust cooling water outlet target temperature, makes its regulation into control panel
Outlet target temperature corresponding with the setting aperture that average aperture is closest.Because the drive energy valve opening of detection can be with
Truly reflect the cooling load of air conditioning area, therefore, the cooling water outlet target temperature after regulation can make refrigeration air-conditioning unit
In the case where meeting the requirement of air conditioning area load, make air-conditioner set more energy efficient.
It is understood that method provided by the invention need not detect outdoor environment temperature, because outdoor environment temperature
The load of air conditioning area can not truly be reacted.And outdoor temperature sensor this device is also saved, reduces cost.
Embodiment of the method two：
Referring to Fig. 2, the figure is the flow chart of embodiment of the method two that air-conditioner set provided by the invention automatically adjusts temperature.
Specific adjusting method is introduced in the present embodiment：
S201-S203 is identical with the S101-S103 difference in embodiment of the method, will not be repeated here.
S204：If first difference is more than zero, and judges that the cold water out temperature of the refrigeration air-conditioning unit is poor
Value is more than the first set temperature value；Then reduce the cooling water outlet target temperature of the refrigeration air-conditioning unit to Tk, the TkIt is corresponding
SVkIt is apart from the SV0A nearest SVi, to increase the cooling load of refrigeration air-conditioning unit output.
S205：If first difference is less than zero, and judges that the cold water out temperature of the refrigeration air-conditioning unit is poor
Value is less than the first design temperature difference；Then increase the cooling water outlet target temperature of the refrigeration air-conditioning unit to Tk, the Tk
Corresponding SVkIt is apart from the SV0A nearest SVi, to reduce the cooling load of refrigeration air-conditioning unit output.
It should be noted that S204 and the steps of S205 two are to be more than the Δ SV in the absolute value of the first differenceiBefore
Put.
It is understood that for refrigeration air-conditioning unit, the cold water out temperature difference refers to cooling water inlet temperature
The difference of degree and cold water outlet temperature.
In the present embodiment before the cooling water outlet target temperature of regulation refrigeration air-conditioning unit, cold water has also been determined whether
Whether out temperature difference meets Rule of judgment, when these segmentation symbols match, just adjusts, so can make refrigeration air-conditioning unit more stably
Work.
