inner machine of air conditioner, simultaneously each humidity transducer equipartition respectively locates in the communication computer lab, in the outdoor many places region real time collection communication computer lab, outdoor each regional humidity, send to the CPU of communication computer lab air conditioner energy-saving control system and calculate the real-time total power consumption of each air conditioner operation in the communication computer lab, judge the operating condition of compressor, actual refrigerating capacity, air conditioner air outlet temperature, near space temperature of inner machine of air conditioner and near temperature of outer machine of air conditioner, by the CPU of communication air conditioner energy-saving control system with each time the real-, The working state of an air conditioner compressor, the actual refrigerating capacity, the air conditioner air outlet temperature, the space temperature near an air conditioner inner unit and the temperature near an air conditioner outer unit are compared and analyzed with corresponding category parameters stored in an experience database, when a certain parameter detected in real time is not within a threshold value of normal operation of the air conditioner, a fault prediction alarm is immediately and actively pushed, the active prediction alarm of the air conditioner fault can be realized by combining an existing communication machine room air conditioner energy-saving control system, so that the communication machine room accurately positions the air conditioner fault, meanwhile, the performance reduction and the potential fault of the air conditioner are early warned by adopting active analysis, the existing machine room energy-saving control system is fully utilized in system design, the air conditioner fault diagnosis and early warning function is realized at low cost, and meanwhile, through further setting, the energy consumption of various devices in the communication machine room and the energy consumption of the, Storing various data of outdoor temperature change into an experience database, combining various data calculated by a CPU according to parameters collected by the experience database to predict the temperature dynamic change trend of each area in the communication machine room, implementing advanced active control of the air conditioner based on the principle of heat energy balance in the communication machine room, wherein the active control correctly predicts the development trend of the temperature of a monitoring point for controlling the operation of the air conditioner in the communication machine room by quantitative detection and calculation of various cold and heat sources inside and outside the communication machine room, actively and in advance makes a control command for controlling the operation of the air conditioner according to the optimal efficiency operation state of the air conditioner, and starts the air conditioner to start the air conditioner to refrigerate at the monitoring point or stops the air conditioner to refrigerate in advance to ensure the internal environment requirement of the communication machine room when the refrigerating capacity reaches the requirement of quitting the monitoring point according to the heat energy balance principle, and simultaneously leads the, the active control is realized by accurately predicting the temperature of the monitoring point in the communication machine room, meanwhile, the accurate prediction is realized by the experience database of the pre-detected historical experience and the heat and temperature prediction algorithm, the problem that the energy-saving effect is influenced by the poor balance of cold and heat quantity due to the fact that the passive energy-saving control has the problem of high-low threshold overshoot of temperature regulation and control caused by the fact that the communication machine room, the space of the communication machine room, the equipment in the communication machine room, the equipment operate and the like have large heat capacity in the conventional air-conditioning energy-saving mode is solved, the required temperature of the internal environment of the machine room is accurately ensured by implementing the active control of the air conditioner according to the principle that the dynamic variation trend of the temperature of each area in the communication machine room is predicted and the heat energy balance is based on the principle, The temperature regulation and control performance is good, the purpose of high efficiency and energy saving is effectively achieved, the dual system integration of large-scale energy saving of the air conditioner of the communication machine room and automatic prediction diagnosis and alarm of the air conditioner fault of the communication machine room is realized, the manufacturing cost of air conditioner fault detection and diagnosis of the communication machine room is greatly reduced, and the communication machine room air conditioner fault detection and diagnosis system can be widely popularized and applied.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
