Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The scheme is based on a cooling chiller as shown in fig. 1. The cooling chiller includes a pre-cooling section 10 and a cooling section 20. The pre-cooling portion 10 is composed of a pre-cooling fan 110, a pre-cooling spray 120, a heat exchange core 130, a pre-cooling water pan 140 and a pre-cooling spray pump 150. When the precooling fan 110 is started and the precooling spray 120 sprays precooling backwater, precooling and cooling can be performed at the heat exchange core 130. The pre-cooling water receiving tray 140 recovers pre-cooling backwater after pre-cooling, and the pre-cooling spray pump 150 is used for providing pressure for pre-cooling backwater sprayed by the pre-cooling spray 120. The cooling part 20 is composed of a cooling fan 210, a cooling spray 220, a filler 230, a cooling water pan 240 and a cooling spray pump 250. When the cooling fan 210 is started and the cooling spray 220 sprays cooling backwater, cooling at the filler 230 can be realized. The cooling water pan 240 recovers the cooled cooling backwater (i.e., cooling water), and the cooling spray pump 250 is used for providing pressure for the cooling backwater sprayed by the cooling spray 220.
On the premise that the pre-cooling part 10 and the cooling part 20 work, the pre-cooling part 10 pre-cools the outdoor inlet air through the pre-cooling spray 120 and the pre-cooling fan 110, so that the cooling inlet air with equal moisture content is obtained. The cooling unit 20 cools the cooling return water by the cooling air intake and the cooling fan 210, thereby obtaining cooling water. The cooling water can be used for cooling equipment in a data center machine room, and then the cooling water chilling unit simultaneously recovers formed cooling backwater so as to be used for generating cooling water in a recirculating manner.
In the process of generating the cooling water, in order to reasonably set the power of the precooling fan and the power of the cooling fan and avoid unnecessary power loss, the scheme needs to generate a first control parameter combination table and a second control parameter combination table through actual measurement in advance. The first control parameter combination table is used for determining smaller power of the cooling fan, and the second control parameter combination table is used for determining smaller power of the pre-cooling fan.
In a specific embodiment, the process of generating the first control parameter combination table is: at first, any two parameters of cooling spray water temperature Ti1 of cooling backwater, cooling air inlet temperature Ti1 of cooling air inlet and cooling fan power Wf2 of a cooling fan are used as first independent variables, and the rest of parameters are used as first dependent variables. And adjusting the parameter value of the first independent variable a plurality of times, and determining the parameter value of the first independent variable such that the temperature of the cooling water reaches the target cooling water temperature Tw. Finally, the parameter value of the first independent variable and the parameter value of the first dependent variable corresponding to the parameter value of the first independent variable are recorded, so that a first control parameter combination table is generated.
Illustratively, the cooling spray water temperature Ti1 and the cooling intake air temperature Ti1 are used as first independent variables, and the cooling fan power Wf2 is used as a first independent variable. Then, firstly setting the parameter value of Ti1 as ti1_a, simultaneously setting the parameter value of Ti1 as Ti1_a, continuously adjusting the parameter value of Wf2, and when the parameter value of Wf2 is wf2_a, meeting the condition that the temperature of cooling water reaches the target cooling water temperature Tw, and at the moment, not adjusting the parameter value of Wf 2. Then, the parameter value Ti1 is set as ti1_a, the parameter value Ti1 is set as ti1_b, the parameter value Wf2 is continuously adjusted, when the parameter value Wf2 is wf2_b, the temperature of the cooling water reaches the target cooling water temperature Tw, and the parameter value Wf2 is not adjusted. And by analogy, the parameter values of the first independent variables are adjusted for a plurality of times, and the parameter values of the corresponding first independent variables are determined.
Finally, summarizing the parameter values, a first control parameter combination table can be obtained as follows:
| Cooling spray Water temperature ti1 | Cooling inlet air temperature Ti1 | Cooling fan power Wf2 |
| ti1_a | Ti1_a | Wf2_a |
| ti1_a | Ti1_b | Wf2_b |
| ti1_b | Ti1_a | Wf2_c |
| …… | …… | …… |
In a specific embodiment, the process of generating the second control parameter combination table is: firstly, taking any one parameter of outdoor air inlet temperature To1 of outdoor air inlet, precooling spray water temperature To1 of precooling backwater and precooling fan power Wf1 of precooling fan as a second independent variable, taking the rest one parameter as a second dependent variable, adjusting parameter values of the second independent variable for a plurality of times, and determining the temperature of cooling air inlet as the parameter values of the second dependent variable in a first control parameter combination table (see the first control parameter combination table, including Ti1_a and Ti1_b); and recording the parameter value of the second independent variable and the parameter value corresponding to the second dependent variable corresponding to the parameter value of the second independent variable to generate a second control parameter combination table.
For example, the outdoor intake air temperature To1 and the pre-cooling spray water temperature To1 are taken as second independent variables, and the pre-cooling fan power Wf1 is taken as a second independent variable. Then, setting the parameter value To1 as to1_a, setting the parameter value To1 as To1_a, and continuously adjusting the parameter value of Wf1, wherein when the parameter value of Wf1 is wf1_a, the cooling air inlet temperature Ti1_a in the first control parameter combination table is satisfied, and at the moment, the parameter value of Wf1 is not adjusted. Then setting the parameter value To1 as To1_a, setting the parameter value Ti1 as To1_b, and continuously adjusting the parameter value of Wf1, wherein when the parameter value of Wf1 is Wf1_b, the temperature of the cooling water is the cooling air inlet temperature Ti1_a, and the parameter value of Wf1 is not adjusted. And by analogy, the parameter values of the second independent variables are adjusted for a plurality of times, and the parameter values of the corresponding second independent variables are determined.
Finally, summarizing the parameter values, a second control parameter combination table can be obtained as follows:
| Precooling spray water temperature to1 | Outdoor air intake temperature To1 | Precooling fan power Wf1 | Cooling inlet air temperature Ti1 |
| to1_a | To1_a | Wf1_a | Ti1_a |
| to1_a | To1_b | Wf1_b | Ti1_a |
| to1_a | To1_a | Wf1_c | Ti1_b |
| …… | …… | …… | …… |
The first control parameter combination table and the second control parameter combination table are combined, so that the target fan power combination with the minimum power sum can be obtained, and the aim of saving energy can be achieved to the greatest extent.
As shown in fig. 2, fig. 2 is a flow chart of a method for controlling a blower according to an embodiment. The fan control method is applied to the cooling water chilling unit shown in fig. 2. The method for controlling the fan in the embodiment comprises the following steps:
And 202, determining n groups of control parameter combinations according to the current cooling spray water temperature of the cooling backwater when the current outdoor air inlet temperature of the outdoor air inlet is higher than a first preset temperature, so that the temperature of the cooling water reaches the target cooling water temperature.
Wherein, a set of control parameter combination includes the cooling fan power Wf2 of a cooling fan and the cooling air inlet temperature Ti1 of a cooling air inlet.
When the current outdoor air inlet temperature of the outdoor air inlet is detected to be higher than the first preset temperature, the outdoor air inlet temperature is too high, the outdoor air inlet needs to be precooled and cooled through the precooling part, otherwise, if the outdoor air inlet is directly used as cooling air inlet to cool the cooling backwater, the cooling water with the target cooling water temperature Tw cannot be obtained, or the cooling water with the target cooling water temperature Tw can be obtained only after a long time.
In a specific embodiment, the step of determining n sets of control parameter combinations comprises: in the first control parameter combination table, the power of the cooling fan and the cooling air inlet temperature corresponding to the current cooling spray water temperature are used as n groups of control parameter combinations. Wherein, the number of n refers to the number of all combinations corresponding to the current cooling spray water temperature in the first control parameter combination table. Referring to the first control parameter combination table, when the current cooling shower water temperature is ti1_a, the n groups of control parameter combinations respectively include ti1_a, wf2_a and ti1_b, wf2_b, and do not include ti1_a, wf2_c.
Therefore, all control parameter combinations can be found based on the current cooling spray water temperature, and the cooling part is controlled based on the control parameter combinations, so that the temperature of the cooling water can be reduced to the target cooling water temperature after the cooling part is cooled down.
And 204, determining the power of n precooling fans of the precooling fans according to the current outdoor air inlet temperature and the current precooling spray water temperature of the precooling backwater so that the temperature of the cooling air inlet is the cooling air inlet temperature in the target control parameter combination.
Wherein the target control parameter combination is any one of n groups of control parameter combinations, namely Ti1_a, wf2_a, ti1_b, wf2_b, or other control parameter combinations
In a specific embodiment, the step of determining the n precooling blower powers is: in the second control parameter combination table, the precooling fan power corresponding to the current outdoor air inlet temperature and the current precooling spray water temperature of precooling backwater is taken as n precooling fan powers. For example, when the target control parameter combination is ti1_a, wf2_a, the current outdoor air inlet temperature is to1_a, and the current pre-cooling spray water temperature of the pre-cooling backwater is To1_a, referring To the second control parameter combination table, the corresponding pre-cooling fan power is wf1_a. For example, when the target control parameter combination is ti1_b, wf2_b, the current outdoor air inlet temperature is to1_a, and the current pre-cooling spray water temperature of the pre-cooling backwater is To1_a, referring To the second control parameter combination table, the corresponding pre-cooling fan power is wf1_c. Similarly, as n groups of control parameter combinations exist, on the premise that the current outdoor air inlet temperature and the current precooling spray water temperature are known, n precooling fan powers can be determined through the second control parameter combination table.
And 206, combining the cooling fan power in the target control parameter combination with n precooling fan powers to obtain n groups of fan power combinations, determining the target fan power combination with the smallest power sum from the n groups of fan power combinations, and controlling the precooling fan and the cooling fan to work by using the target fan power combination.
Specifically, based on steps 202 and 204, it may be determined that on the premise that the current pre-cooling spray water temperature is To1_a, the current outdoor air inlet temperature is To1_a, the current cooling spray water temperature is ti1_a, and the target cooling water temperature is Tw, the n sets of fan power combinations include wf2_a, wf1_a, wf2_b, and wf1_c, and of course, based on actual measurement, other sets of fan power combinations should be included. And adding the two parameter values in each group of fan power combinations, and taking the fan power combination with the minimum parameter value as a target fan power combination. The target fan power combination is used for controlling the work of the precooling fan and the cooling fan, so that the aim of saving energy to the greatest extent can be fulfilled.
According to the fan control method, when the current outdoor air inlet temperature of the outdoor air inlet is detected to be higher than the first preset temperature, the current cooling spray water temperature of the cooling backwater and the target cooling water temperature of the cooling water are obtained, n groups of control parameter combinations are determined according to the current cooling spray water temperature, and the temperature of the cooling water after cooling reaches the target cooling water temperature; wherein, the set of control parameter combinations comprises a target cooling fan power of a cooling fan and a target cooling air inlet temperature of a cooling air inlet; determining n target precooling fan powers of the precooling fans according to the current outdoor air inlet temperature, so that the temperature of the cooled air inlet after precooling is the target cooling air inlet temperature in the target control parameter combination; and then taking the target cooling fan power in the target control parameter combination and the target precooling fan power corresponding to the target control parameter combination as a group of fan power combinations to obtain a group of fan power combinations, so that all feasible fan power combinations can be obtained. And finally, determining that the power sum is the minimum from n groups of fan power combinations as a target fan power combination, and controlling the work of the precooling fan and the cooling fan by using the target fan power combination so as to achieve the aim of saving energy.
In a specific embodiment, when the temperature of the outdoor air intake is detected to be lower than or equal to the first preset temperature, the temperature of the outdoor air intake is lower, and at this time, the outdoor air intake is not required to be precooled and cooled through the precooling part, and can be directly used as cooling air intake to cool the cooling backwater, so that the cooling water with the target cooling water temperature Tw can be obtained quickly. And the precooling part is closed, the current outdoor air inlet temperature is directly used as the cooling air inlet temperature, and the independent working power of the cooling fan is determined according to the current cooling spray water temperature and the cooling air inlet temperature, so that the temperature of the cooling water reaches the target cooling water temperature, and the cooling fan is controlled to work by the independent working power.
Specifically, when the current cooling spray water temperature is ti1_a and the cooling air inlet temperature is ti1_a, referring to the first control parameter combination table, the independent working power of the cooling fan is set to wf2_a. Therefore, the cooling water with the target cooling water temperature Tw can be obtained on the premise of not starting the pre-cooling part, and energy conservation is realized to the greatest extent.
In one embodiment, as shown in fig. 3, a fan control apparatus is provided, the apparatus comprising:
