Abstract
The invention provides a method and a system for automatically adjusting a temperature of an air conditioning unit. The method comprises the steps that an average aperture SV0 of a driving energy valve of the air conditioning unit within the preset time and current outlet target temperatures of the air conditioning unit are detected; subtracting is carried out on the average aperture SV0 and a set aperture corresponding to the current outlet target temperatures to obtain a first difference value; multiple set apertures SVi are arranged on a control disc of the air conditioning unit; one set aperture SVi corresponds to one outlet target temperature Ti; if an absolute value of the first difference value is smaller than or equal to a first preset threshold value delta SVi, the current outlet target temperatures are maintained; and if the absolute value of the first difference value is larger than the delta SVi, the outlet temperatures of the air conditioning unit are adjusted to Tk, and the SVk corresponding to the Tk is the nearest SVi from the SV0. Due to the fact that the detected aperture of the driving energy valve can reflect the refrigerating load of an air conditioning area truly, the adjusted target temperatures of cold water outlets can meet the requirement within the air conditioning load, and the air conditioning unit can save more energy.
Description
Technical field
The present invention relates to automatic temperature-control technical field, particularly a kind of air-conditioner set regulates the method and system of temperature automatically.
Background technology
According to inverse Carnot cycle theorem, in refrigeration machine and heat pump, under meeting user's cold or heat demand, when the cryogenic temperature set or heat temperature close with environment temperature time, the coefficient of performance of air-conditioner set can improve, and operate relative energy-saving under this operating mode.
Therefore, need air-conditioner set work to meet the demand of user shortly, under operating mode as far as possible energy-conservation again.
The control mode taked in prior art is introduced below for the cooling condition of air-conditioner set.Air-conditioner set arranges environment temperature sensor, for detecting outdoor environment temperature T0.Design temperature in T0 and control panel is compared.The drive energy valve opening of adjusting air conditioning group is carried out according to comparative result.
Driven by energy valve refers to and is realizing in certain equipment of running by the various energy as power, is changed various valve or the similar device of its output capacity by the aperture of the change input energy.Fuel valve, steam control valve door, hot-water valve etc. espespecially in absorption cooling and warming water machine or heat pump, and the inlet valve of power supply input in electric refrigerating machine or heat pump, guiding valve even variable-frequency pulse signal etc.
But there is following drawback in this mode: outdoor environment temperature can not react the load condition of air conditioning area truly, namely the demand of user and outdoor environment temperature inconsistent sometimes.Such as, outdoor environment temperature is high sometimes, but air conditioning area load is low; Or outdoor environment temperature is low, but air conditioning area load is larger.The load of air conditioning area depends primarily on the summation of transferring heat in the export-oriented region of intra-zone self-radiating amount and region.Such as, outdoor temperature higher but in air conditioning area personnel less or heat dissipation equipment is less time, do not need the temperature to air conditioning area cooling too low, vice versa.Outdoor temperature is lower, but when air conditioning area personnel are more or heat dissipation equipment is more, needs the temperature lower ability practical requirement to air conditioning area cooling.In addition, environment temperature sensor is disposed in the outdoor, distant with host computer control dish, and affected by environment too large, disturbing factor is more, and the outdoor environment temperature fed back like this is also not too accurate.
Therefore, those skilled in the art need to provide a kind of air-conditioner set automatically to regulate the method for temperature, truly can reflect the load of air conditioning area, not by the impact of outdoor environment temperature, and the outlet target temperature of automatic adjusting air conditioning group.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
For enabling above-mentioned purpose of the present invention, feature and advantage become apparent more, are described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
Outdoor environment temperature is not detected in the embodiment of the present invention, but direct-detection drive energy valve opening, because drive energy valve opening truly can reflect the load of air conditioning area, carry out the outlet target temperature of automatic adjusting air conditioning group according to the drive energy valve opening detected.It should be noted that, refrigeration air-conditioning unit is identical with the control principle of cooling/heating air conditioner unit, is introduced respectively below, first introduces the temperature-controlled process of refrigeration air-conditioning unit.
Embodiment of the method one:
See Fig. 1, this figure is embodiment of the method one flow chart that air-conditioner set provided by the invention regulates temperature automatically.
The air-conditioner set that the present embodiment provides regulates the method for temperature automatically, is applied to refrigeration air-conditioning unit, comprising:
S101: the drive energy valve average aperture SV in the given time detecting described refrigeration air-conditioning unit
0the cooling water outlet target temperature current with described refrigeration air-conditioning unit;
Such as, current cooling water outlet target temperature is 16 degrees Celsius.
S102: by described average aperture SV
0the setting aperture corresponding with described current cooling water outlet target temperature does poor acquisition first difference; Multiple setting aperture SV is set in the control panel of described refrigeration air-conditioning unit
i; A described setting aperture SV
ia corresponding cooling water outlet target temperature T
i; I=1 ... n, wherein n is the integer value of setting;
It should be noted that, the setting aperture in control panel is multiple, such as: SV
1, SV
2, SV
3sV
n.
The cooling water outlet target temperature that different setting apertures is corresponding is different, such as, and SV
1corresponding cooling water outlet target temperature is T
1, SV
2corresponding cooling water outlet target temperature is T
2, SV
3corresponding cooling water outlet target temperature is T
3, SV
ncorresponding cooling water outlet target temperature is T
n.
Such as, 16 degrees Celsius of corresponding setting apertures are 20%, then by SV
0poor acquisition first difference is done with 20%.
S103: if the absolute value of described first difference is less than or equal to the first predetermined threshold delta SV
i, then described current cooling water outlet target temperature is maintained;
Be understandable that, the absolute value of the first difference is less than or equal to the first predetermined threshold, then do not need to regulate drive energy valve opening, keeps current aperture and current cooling water outlet target temperature.
S104: if the absolute value of described first difference is greater than described Δ SV
i, then regulate the cooling water outlet target temperature of described refrigeration air-conditioning unit to T
k, described T
kcorresponding SV
kapart from described SV
0a nearest SV
i.
Be understandable that, when the absolute value of the first difference is greater than the first predetermined threshold, represent that current cooling water outlet target temperature does not meet the cooling load of client's air conditioning area, need to regulate cooling water outlet target temperature, the mode of adjustment is the cooling water outlet target temperature by finding the setting aperture nearest with average aperture corresponding.Like this, refrigeration air-conditioning unit can be made more energy-conservation.
In order to the technical scheme making those skilled in the art more clearly understand the introduction of above embodiment, be further detailed below in conjunction with table 1.
Table 1
As can be seen from Table 1, SV
0be 22.0%, suppose that current cooling water outlet target temperature is 16, then the setting of 16 degree of correspondences starts to be 20%.Therefore, SV
0to do the first poor difference be 2%< Δ SV with 20%
i=2.5%; Therefore, keep current cold water outlet temperature constant, namely continue as 16 degrees Celsius.
Be understandable that, suppose that the drive energy valve opening detected is not 22.0%, but 24.0%.Now the 24.0% setting aperture 20% corresponding with 16 degree does the first poor difference is 4%.Due to 4%> Δ SV
i=2.5%; Therefore, need to regulate cooling water outlet target temperature, as can be seen from Table 1, setting aperture 25% is nearest with the average aperture 24.0% detected, therefore, the outlet target temperature of refrigeration air-conditioning unit is adjusted to the cooling water outlet target temperature 14 degrees Celsius of 25% correspondence.Because the drive energy valve opening that detects can the load of actual response air conditioning area, therefore, remain running in the requirement that 16 degrees Celsius have not met air conditioning area load, the cooling water outlet target temperature after adjustment can, under the requirement meeting air conditioning area load, make air-conditioner set more energy-conservation.
The method that the present embodiment provides, detect the drive energy valve opening of refrigeration air-conditioning unit and current cooling water outlet target temperature, the setting aperture that drive energy valve opening is corresponding with current cooling water outlet target temperature is carried out doing difference, if the absolute value of difference is greater than the first predetermined threshold, then need to regulate cooling water outlet target temperature, make it be adjusted to outlet target temperature corresponding to setting aperture nearest with average aperture in control panel.Because the drive energy valve opening detected can reflect the cooling load of air conditioning area truly, therefore, the cooling water outlet target temperature after adjustment can make refrigeration air-conditioning unit under the requirement meeting air conditioning area load, makes air-conditioner set more energy-conservation.
Be understandable that, method provided by the invention does not need to detect outdoor environment temperature, because outdoor environment temperature can not react the load of air conditioning area truly.And also save this device of outdoor temperature sensor, reduce costs.
Embodiment of the method two:
See Fig. 2, this figure is embodiment of the method two flow chart that air-conditioner set provided by the invention regulates temperature automatically.
Concrete control method is introduced in the present embodiment:
S201-S203 is identical respectively with the S101-S103 in embodiment of the method, does not repeat them here.
S204: if described first difference is greater than zero, and judge that the cold water out temperature difference of described refrigeration air-conditioning unit is greater than the first set temperature value; Then reduce the cooling water outlet target temperature of described refrigeration air-conditioning unit to T
k, described T
kcorresponding SV
kapart from described SV
0a nearest SV
i, to increase the cooling load that refrigeration air-conditioning unit exports.
S205: if described first difference is less than zero, and judge that the cold water out temperature difference of described refrigeration air-conditioning unit is less than described first design temperature difference; Then increase the cooling water outlet target temperature of described refrigeration air-conditioning unit to T
k, described T
kcorresponding SV
kapart from described SV
0a nearest SV
i, to reduce the cooling load that refrigeration air-conditioning unit exports.
It should be noted that, S204 and S205 two step is all be greater than described Δ SV at the absolute value of the first difference
iprerequisite under.
Be understandable that, for refrigeration air-conditioning unit, described cold water out temperature difference refers to the difference of cooling water inlet temperature and cold water outlet temperature.
In the present embodiment before the cooling water outlet target temperature regulating refrigeration air-conditioning unit, also judge whether cold water out temperature difference meets Rule of judgment further, when these segmentation symbols match, just regulated, refrigeration air-conditioning unit can be made so more stably to work.
For refrigeration air-conditioning unit, the method that the above embodiment of the present invention provides can make refrigeration air-conditioning unit under the requirement meeting air conditioning area load, make air-conditioner set more energy-conservation, schematic diagram that specifically can be shown in Figure 3, the graph of a relation of drive energy valve opening and cooling water outlet target temperature, as can be seen from Figure 3, drive energy valve opening is larger, and corresponding cooling water outlet target temperature is lower.
Embodiment of the method three:
See Fig. 4, this figure is embodiment of the method three flow chart that air-conditioner set provided by the invention regulates temperature automatically.
The regulative mode of the refrigeration air-conditioning unit that above embodiment is introduced, introduce the regulative mode of cooling/heating air conditioner unit below, the Principles of Regulation of application are identical, but, freeze and the adjustment direction that heats different.
The method that the present embodiment provides, is applied to cooling/heating air conditioner unit, comprises:
