Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples and the accompanying drawings, and the exemplary embodiments and descriptions thereof are only used for explaining the present invention and are not used as limiting the present invention.
Example one
As shown in fig. 1, an embodiment of the present application provides a machine room load power adaptive control method, which is mainly applied to control output power of an environment conditioning device in a data center machine room, so as to reduce energy consumption of the environment conditioning device in the machine room, and includes:
step 110, collecting air inlet temperature and humidity parameters, air outlet temperature and humidity parameters and total power generated by equipment in a machine room of the wet curtain fan in equal time periods;
in this embodiment, at least one set of temperature and humidity sensors is arranged at the air inlet and the air outlet and is respectively used for detecting air inlet temperature and humidity parameters and air outlet temperature and humidity parameters, and if only one set of temperature and humidity sensors is provided, the air inlet temperature and humidity and the air outlet temperature and humidity measured by the set of temperature sensors at the current moment can be used as temperature and humidity data of the air inlet temperature and humidity and the air outlet temperature and humidity. In order to improve the measurement accuracy and avoid temperature and humidity fluctuation or measurement errors, the average value of the temperature and humidity of the air inlet and the average value of the temperature and humidity of the air outlet, which are measured by the temperature sensors in a period of time, can be used as temperature and humidity data of the temperature and humidity of the air inlet and the temperature and humidity of the air outlet. If M groups of temperature sensors exist, M is more than or equal to 2, the temperature of the M groups of air inlets and the temperature of the air outlets can be collected at the same time, the average value or the highest value of the humiture of the multiple groups of air inlets is used as humiture data of the humiture of the air inlets, and the average value or the highest value of the humiture of the multiple groups of air outlets is used as humiture data of the humiture of the air outlets.
For the total power generated by the devices in the machine room, such as a computer, a server, a gateway and the like, the total power can be obtained by collecting the voltage and the current at the power switch through the reading device.
Step 120, calculating heat taken away by the wet curtain fan according to the air inlet temperature and humidity parameters and the air outlet temperature and humidity parameters;
in this embodiment, the heat of the wet curtain fan is calculated according to the air inlet temperature and humidity parameters and the air outlet temperature and humidity parameters of the machine room acquired in the step 110, and according to a basic physical formula: q is c m Δ t, Q is the ability to take away heat, where c is the specific heat capacity of the object, m is the ventilation volume per unit time (related to the wind speed of the wet curtain fan), Δ t is the temperature difference between the air inlet and the air outlet, and it is known from this formula that c, m, and Δ t need to be added in order to increase Q, which is the principle of the evaporative wet curtain fan; and regarding the humidity, the humidity is expressed by the moisture content in the air, so that the water adding amount of the evaporative wet curtain fan is controlled by a program, and c (the specific heat capacity is large, namely 1030J/(kg DEG C), 4200J/(kg DEG C)) can be increased, the specific heat capacity is increased, m is increased, the ventilation volume per unit time is increased, and the temperature of the air inlet is reduced due to the heat taken away by the evaporation of the water, so that delta t is also increased.
Step 130, calculating the cooling and humidifying capacity of the wet curtain fan when the machine room reaches a preset temperature and humidity threshold value according to the total power and the heat, and setting the wind speed and the humidifying strength of the wet curtain fan according to the cooling capacity;
in this embodiment, it should be noted that the cooling and humidifying capability is a cooling effect and a humidity effect that can be achieved by the wet curtain fan at a certain rotation speed and a certain water addition amount.
At a certain time interval, the total power of the machine room is multiplied by time to generate corresponding heat, and the heat which can be taken away by the wet curtain fan under corresponding operation parameters is quantitative, so that the cooling and humidifying capacity of the wet curtain fan when the machine room reaches a preset temperature and humidity threshold value is calculated according to the real-time heat generated by the real-time power of machine room equipment and the heat which can be taken away by the wet curtain fan under a certain operation parameter, the setting of the wind speed and the humidifying strength of the wet curtain fan is executed according to the cooling capacity, and the popular point is that the environmental parameters in the machine room can be controlled under appropriate conditions only by adjusting the rotating speed and the water adding amount of the wet curtain fan to certain values.
Step 140, obtaining the data slope of the temperature and the humidity in the machine room according to the data collected by the temperature and humidity sensor in the machine room in the equal time period;
in this embodiment, the equal time period is generally set to 1 minute or 2 minutes, which has little influence on the environmental deployment of the machine room, and when calculating the data slope of the temperature and humidity data, the minutes need to be converted into seconds, and some data with obvious deviation need to be discarded, so as to ensure the accuracy of the data slope.
Step 150, analyzing the current cooling and humidifying capacity of the current control parameter of the wet curtain fan according to the trend of the data slope;
in this embodiment, whether the current cooling and humidifying capacity of the current control parameter of the wet curtain fan meets the preset temperature and humidity threshold is analyzed according to the rising or falling trend of the data slope of the temperature and humidity data calculated in step 140, for example, when the change of the rising slope of the temperature data is large, that is, when the change of the current temperature in the previous period is large, that is, the rotation speed of the wet curtain fan needs to be increased, so as to reduce the indoor temperature, and for example, when the change of the rising slope of the humidity data is large, that is, when the change of the current indoor humidity in the previous period is large, the water addition amount of the water curtain of the wet curtain fan needs to be reduced, so as to reduce the water content in the air, if the maximum value of the specified humidity range is exceeded, but the condition that the dehumidification needs to be performed through the air conditioner is not reached, the water addition of the water curtain of the wet curtain fan can be stopped, and the heat in the room is used to melt the water content in the air, therefore, the effect of real-time adjustment is achieved, and the machine room is ensured to be in a proper temperature range and humidity range. It should be noted that, for the case where the data slope change is smooth and is in a descending state, the operation parameters of the wet curtain fan are adjusted by the same control principle.
And step 160, if the current cooling and humidifying capacity is lower than the cooling and humidifying capacity, adjusting the wind speed and the humidifying intensity of the wet curtain fan to control the cooling and humidifying capacity, and otherwise, waiting for the next time period to acquire the parameters of the wet curtain fan again to control the cooling and humidifying capacity.
In this embodiment, current cooling humidification ability is less than cooling humidification ability, shows that the operating parameter of wet curtain fan can't satisfy the regulation and control of computer lab internal environment at the present moment, then needs the wind speed and the humidification intensity of readjustment wet curtain fan to increase the cooling humidification ability of wet curtain fan. When present cooling humidification ability is greater than or equal to cooling humidification ability, then it is suitable to explain current operating parameter, need wait for the air intake of wet curtain fan of equal time period next time, the air intake humiture parameter of air outlet, air outlet humiture parameter, and the total power that equipment produced in the computer lab, because the total power of computer lab can change, the cooling humidification ability of so wet curtain fan also can follow the regulation change, can accomplish the regulation to cooling humidification ability according to follow-up step again, thereby realize the self-adaptation control to the load power of computer lab environmental control equipment, reach energy-conserving effect to the at utmost.
It is understood that, regarding the current requirements for a data center room, the room temperature is 20-25 degrees, and the room humidity is 40-55%, which is considered to be a more suitable indoor environment.
According to the technical scheme, the self-adaptive control method comprises the steps of calculating the cooling and humidifying capacity of a wet curtain fan when the temperature and humidity of a machine room reaches a preset temperature and humidity threshold value through the total power generated by a server in the machine room and the heat taken away by the wet curtain fan, then collecting data in the machine room at equal time intervals, obtaining the data slope of the temperature and humidity according to the data, analyzing the current cooling and humidifying capacity of the current wet curtain fan according to the change trend of the data slope, and regulating and controlling the operation parameters of the wet curtain fan according to the current cooling and humidifying capacity and the cooling and humidifying capacity when the temperature and humidity threshold value needs to be reached.
In a scheme that probably realizes, if current cooling ability is less than the cooling ability adjusts the wind speed and the humidification intensity of wet curtain fan, realizes the control to the cooling ability, otherwise then waits for next regulation cycle, includes:
and dividing the allowance proportion of the total power and the heat equally, if the rising slope of the temperature and humidity data is greater than a preset temperature and humidity slope threshold value, increasing the divided proportion value on the current allowance proportion, and adjusting the wind speed and the humidification intensity of the wet curtain fan until the rising slope of the temperature and humidity data is not greater than the preset temperature and humidity slope threshold value.
Specifically, the real-time total power of the machine room is collected, and theoretically, the heat is the same as the total power of the machine room, but actually, a certain margin ratio exists: at present, the cooling capacity is controlled by 10% -100%, the cooling capacity is controlled by subdividing according to 10%, if the temperature rising slope is too large, the allowance proportion can be increased, the machine room achieves dynamic balance of temperature, and the coordination controller mainly adjusts the water speed (the moisture added on the wet curtain) and the wind speed of the fresh air of the wet curtain. A (c)
Example two
As shown in fig. 2, in a second embodiment of the present application, on the basis of the first embodiment, the adaptive control method further includes:
acquiring load parameters of a wet curtain fan and temperature and humidity data in a machine room;
if the load parameter of the wet curtain fan reaches the maximum load power, the temperature in the machine room does not meet the temperature threshold value, the air conditioner is started to cool, the wet curtain fan is closed, or the humidity data in the machine room is larger than the maximum humidity threshold value, the air conditioner is started to dehumidify, and the wet curtain fan is closed.
Specifically, it should be noted that the energy consumption of the air conditioner is higher than that of the wet curtain fan at the same time, so that the wet curtain fan is mainly controlled and adjusted and the air conditioner is secondarily controlled and adjusted in terms of temperature and humidity adjustment.
In this embodiment, in one implementation, when the temperature continuously rises and the effective control of the temperature cannot be completed by the wet curtain fan, the air conditioner needs to be started to adjust the environmental parameters of the machine room; therefore, when the rotating speed of the wet curtain fan is the maximum rotating speed, the temperature in the machine room still does not meet the set temperature threshold value, and the air conditioner needs to be started to cool. In another embodiment, when the indoor humidity reaches the maximum humidity threshold, immediate dehumidification is required, because the higher the humidity is, the more the water content in the air is, and when the data equipment in the machine room is in operation, if the water content in the surrounding air is higher, the equipment may absorb the water in the air, so that the rusting condition of components such as the internal circuit board of the equipment may be caused, the service life of the data equipment may be reduced, and therefore, the air conditioning dehumidification may be required to be started.
In a scheme that probably realizes, gather and cool down and dehumidify the current real-time humiture of back computer lab through the air conditioner, judge whether real-time humiture satisfies the start condition of wet curtain fan, if satisfy then close the air conditioner, start the humiture of wet curtain fan to the computer lab and adjust, if unsatisfied then continue to start the air conditioner and cool down or dehumidify.
