Air conditioner working state feedback system and method

Abstract

The invention discloses an air conditioner working state feedback system and method which are used for feeding back the running state of an air conditioner. The feedback system comprises an intelligent control panel connected with the air conditioner. The air conditioner comprises an inner draught fan. The feedback system further comprises a detection module connected between the inner draught fan and the intelligent control panel. A pressure difference switch or a pressure difference sensor can serve as the detection module. The air conditioner working state feedback system and method have the advantages that the pressure difference switch or the pressure difference sensor serves as the detection module in the air conditioner working state feedback system, a connection line connected to the intelligent control panel can be a passive line, the safety performance is high, and the problem that when the energy-saving updating and refitting are conducted on a traditional base station, due to the problems of the intelligent control panel, a null line and a live wire of the base station are short circuited is solved. In addition, the work complexity of the operation, maintenance and on-site installation of the base station is lowered, an existing base station air conditioner does not need to be refitted, and the air conditioner working state feedback system and method can be well compatible with different brands and types of base station air conditioners.

Description

technical field [0001] The invention relates to the field of air conditioners, and more specifically relates to an air conditioner working state feedback system and method for communication base stations. Background technique [0002] The communication base station is an important part of the communication system. Its internal temperature and cleanliness and other environmental parameters directly affect the reliable operation and service life of the communication equipment, and the communication equipment belongs to the uninterrupted high-load operation throughout the year and generates a lot of heat. Even in winter Refrigeration is also required. Therefore, the air conditioner must also run uninterrupted throughout the year. In the base station where the air conditioner is installed, the power consumption of the air conditioner accounts for 45% of the total power consumption. [0003] At present, the temperature in the base station is generally set at 28°C. The heat excha...

Problems solved by technology

[0004] The current control methods of linked air conditioners include power supply, buttons, and infrared, and the control of linked air conditioners needs to detect the feedback of the air conditioner to judge whether the control is effective. The current feedback method of the combined air conditioner is to detect the voltage signal of the fan inside the air conditioner of the base station. The method has the following problems: 1) It is necessary to disassemble the air conditioner of the base station, and lead the connecting wire of the internal fan of the base station to the intelligent control board, so it is necessary to extend the strong electric signals such as the live wire and the neutral wire of the power supply to the intelligent control board, which is easy to Potential safety hazards may result in the power outage of the entire communication base station; 2) The internal unit of the air conditioner has a small space and the wiring inside is complicated, and the installer may easily damage the original air conditioning system during operation; 3) The DC used by some air conditioners Fan, the voltage signal is inconsistent, resulting in poor system compatibility
