Description

一种间接蒸发冷冷源泵喷淋控制方法及控制装置Indirect evaporative cold source pump spray control method and control device 技术领域Technical field
本发明涉及制冷技术领域，更具体地说，涉及一种间接蒸发冷冷源泵喷淋控制方法及控制装置。The invention relates to the technical field of refrigeration, and more specifically, to a spray control method and a control device of an indirect evaporative cold source pump.
背景技术Background technique
对于间接蒸发冷机组来说，有三种运行模式。干工况模式、湿工况模式、湿工况模式+压缩机模式的混合模式。干工况模式是通过室外空气直接和室内空气进行换热的模式；湿工况模式是通过喷淋系统给室外空气进行喷淋，先降低室外空气的温度，然后室外空气再和室内空气进行换热，降低室内空气温度；湿工况模式+压缩机模式是通过喷淋系统给室外空气进行喷淋，先降低室外空气的温度，然后室外空气再和室内空气进行换热，降低室内空气温度，然后室内空气再经过蒸发器获取冷量给室内送风。由上述过程可以得出，喷淋系统在湿工况运行和湿工况+压缩机混合模式下，喷淋的开启条件整个喷淋系统的喷淋效率有非常大的影响，对整个系统的节能也有很大的影响。For indirect evaporative chillers, there are three operating modes. Mixed mode of dry working mode, wet working mode, wet working mode + compressor mode. Dry working mode is a mode in which outdoor air is directly exchanged with indoor air; wet working mode is to spray outdoor air through a spray system, first reduce the temperature of outdoor air, and then outdoor air exchanges with indoor air Heat, reduce the indoor air temperature; the wet working mode + compressor mode sprays the outdoor air through the spray system, first reduces the temperature of the outdoor air, and then the outdoor air exchanges heat with the indoor air to reduce the indoor air temperature. Then the indoor air passes through the evaporator to obtain cold energy and supply air to the room. From the above process, it can be concluded that when the spray system is operating in wet conditions and in the mixed mode of wet conditions + compressor, the opening conditions of the spray have a great impact on the spray efficiency of the entire spray system, which has a great impact on the energy saving of the entire system. It also has a big impact.
此外在水喷淋过程中，水会吸收室外空气和室内空气的热量，温度逐渐升高高于室外空气温度，这时继续开喷淋，会出现给室外空气增焓升温的过程，将大大降低喷淋的效果，所以控制水箱喷淋的开启就显得尤为重要。In addition, during the water spraying process, the water will absorb the heat of outdoor air and indoor air, and the temperature will gradually rise higher than the outdoor air temperature. If the spraying is continued at this time, a process of increasing the enthalpy of the outdoor air will occur, which will greatly reduce The effect of spraying, so it is particularly important to control the opening of the water tank spray.

本发明的实施方式Embodiments of the invention
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。In order to have a clearer understanding of the technical features, objectives and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
如图1所示，在本发明的一种间接蒸发冷冷源泵喷淋控制方法第一实施例中，包括以下步骤：S1、获取室外温度Ta；S2、在室外温度Ta高于第一预设温度Tb时，获取进入冷源泵的冷源温度Tc；S3、在冷源温度Tc低于室外温度Ta时，开启冷源泵。具体的，这里冷源可以为各种制冷剂，例如常用的水，这里冷源泵采用水泵进行具体的说明，如果室外温度过低时，室内空气可以与室外空气进行间接换热来获取冷量，此时不需要开启水泵喷淋给室外空气进行降温，这样可以充分的节约水资源，减少系统的能耗。当室外温度Ta高于第一预设温度Tb时，如果进入水泵的水温过高，一般造成水泵水温过高的原因：水系统在运行过程中，喷淋水在换热器中要和室外空气和室内空气都会发生热量的交换导致水温升高，那么再进行喷淋来降低室外空气温度，由于两者的温差较小，热量交换的动力会变小，喷淋效率会降低，所以只有当水温即可以理解为水泵泵的水温Tc低于室外温度Ta时，水泵喷淋装置即可以理解为水泵才会开启，而在水泵泵的水温Tc高于室外温度Ta时，水泵喷淋装置即可以理解为水泵关闭，可以大大提高喷淋效率。As shown in Figure 1, in the first embodiment of the indirect evaporative cold source pump spray control method of the present invention, the method includes the following steps: S1, obtain the outdoor temperature Ta; S2, when the outdoor temperature Ta is higher than the first preset When the temperature Tb is set, the cold source temperature Tc entering the cold source pump is obtained; S3, when the cold source temperature Tc is lower than the outdoor temperature Ta, the cold source pump is turned on. Specifically, the cold source here can be various refrigerants, such as commonly used water. Here, the cold source pump uses a water pump for specific instructions. If the outdoor temperature is too low, the indoor air can exchange heat with the outdoor air indirectly to obtain the cold. At this time, there is no need to start the water pump to spray to cool the outdoor air, which can fully save water resources and reduce the energy consumption of the system. When the outdoor temperature Ta is higher than the first preset temperature Tb, if the temperature of the water entering the water pump is too high, the general reason for the high water temperature of the water pump is: during the operation of the water system, the spray water in the heat exchanger should be combined with the outdoor air The heat exchange with indoor air will cause the water temperature to rise, then spray to lower the outdoor air temperature. Because the temperature difference between the two is small, the power of heat exchange will be smaller and the spray efficiency will be reduced, so only when The water temperature can be understood as when the water temperature Tc of the water pump is lower than the outdoor temperature Ta, the water pump spray device can be understood as the water pump will be turned on, and when the water temperature Tc of the water pump is higher than the outdoor temperature Ta, the water pump spray device can It is understood that the water pump is closed, which can greatly improve the spray efficiency.
进一步的，本发明的种间接蒸发冷冷源泵喷淋控制方法还包括：Further, the indirect evaporative cold source pump spray control method of the present invention further includes:
S21、设置一基本温度T,并设置冷源泵的工作模式；S21. Set a basic temperature T and set the working mode of the cold source pump;
S22、当冷源泵工作在第一模式时，第一预设温度Tb小于基本温度T；S22. When the cold source pump is working in the first mode, the first preset temperature Tb is less than the basic temperature T;
S23、当冷源泵工作在第二模式时，第一预设温度Tb大于基本温度T。S23. When the cold source pump works in the second mode, the first preset temperature Tb is greater than the basic temperature T.
具体的，依然以水泵为例，可以根据水泵的工作模式进行第一预设温度Tb的设置，根据水泵的一般工作情况设置水泵的基本温度T，当水泵工作在第一工作模式即节电模式时，可以设置为第一预设温度Tb小于基本温度T，当水泵工作在第二工作模式即节水模式时，可以设置为第一预设温度Tb高于基本温度T。可以理解，节水模式和节电模式主要是针对水泵喷淋开启的最小温度来确定的，比如一般的喷淋开启的最小温度设置为15℃即基本温度T，如果要控制水泵工作在节水模式，可以将水泵开始开启的最小温度设置为高于T，即Tb>15℃，例如可以设置为16℃、17℃、18℃等等，通过调高喷淋最小温度的值来达到节水模式的主要原因是：在一段时间中，喷淋的最小温度设置的越高，喷淋系统开启的次数越小，那么所需要要喷淋的水量就越小，总体喷淋过程中所蒸发的水量和室外风机带出的水量就越小，所以所消耗的总体水量就会越小，故设置喷淋的最小温度越高，所消耗的水资源就越小，故能达到节水的目的；而对于节电模式而言：比如一般的喷淋开启的最小温度设置为15℃即基本温度T，那么如果现在要进行节电模式，可以将水泵开始开启的最小温度设置为低于T，即Tb<15℃，例如可以调节到14℃、13℃、12℃等等，通过调低喷淋最小温度的值来达到节点模式的主要原因是：在一段时间中，喷淋的最小温度设置的越低，那么喷淋系统开启的次数就多，那么喷淋水就可以把更多的冷量给室外空气，然后室内空气与室外空气进行换热也会获得更多的冷量，这样系统开启压缩机的次数就会变少（一般压缩机的功率较大），整体系统所消耗的电能也就越少，故设置喷淋的最小温度越低，所消耗的电能就越小，故能达到节电的目的。可以基本温度T为常规模式设置的冷源泵的开启温度，也可以理解为冷源泵的默认工作模式，如果不调节节水模式和节电模式，那么冷源泵的工作模式就常规的工作模式。Specifically, still taking the water pump as an example, the first preset temperature Tb can be set according to the working mode of the water pump, and the basic temperature T of the water pump can be set according to the general working conditions of the water pump. When the water pump is working in the first working mode, the power saving mode When the first preset temperature Tb is lower than the basic temperature T, when the water pump works in the second working mode, that is, the water saving mode, the first preset temperature Tb may be set higher than the basic temperature T. It can be understood that the water-saving mode and the power-saving mode are mainly determined for the minimum temperature at which the spray of the water pump is turned on. For example, the minimum temperature of the general spray opening is set to 15℃, which is the basic temperature T. If you want to control the pump to work in water saving Mode, you can set the minimum temperature at which the pump starts to be higher than T, that is, Tb>15°C, for example, it can be set to 16°C, 17°C, 18°C, etc., and save water by increasing the minimum spray temperature The main reason for the mode is: in a period of time, the higher the minimum spray temperature setting, the smaller the number of times the spray system is turned on, the smaller the amount of water needed to spray, and the overall spraying process will evaporate The smaller the amount of water and the amount of water brought out by the outdoor fan, the smaller the overall amount of water consumed. Therefore, the higher the minimum temperature of the spray, the smaller the water consumption, so the purpose of water saving can be achieved; For the power saving mode: for example, the minimum temperature of the general spray opening is set to 15℃, which is the basic temperature T. If you want to use the power saving mode now, you can set the minimum temperature at which the pump starts to be lower than T, that is Tb<15°C, for example, it can be adjusted to 14°C, 13°C, 12°C, etc. The main reason for reaching the node mode by lowering the minimum spray temperature is: in a period of time, the minimum spray temperature is set The lower the value, the more times the sprinkler system will be turned on, then the sprinkler water can give more cold to the outdoor air, and then the indoor air and outdoor air will exchange heat to obtain more cold, so that the system is turned on The number of compressors will be less (generally the compressor has a higher power), and the overall system will consume less electricity. Therefore, the lower the minimum temperature for spraying, the less electricity will be consumed, so it can reach The purpose of power saving. The basic temperature T can be the starting temperature of the cold source pump set in the normal mode, or it can be understood as the default working mode of the cold source pump. If the water saving mode and power saving mode are not adjusted, then the working mode of the cold source pump will be normal. mode.

The purpose of this is mainly that the heat exchange channels of outdoor air and indoor air are closed to each other under wet conditions.
