Energy saver for base station machine room air conditioners

Abstract

The invention relates to an energy saver for base station machine room air conditioners. The invention solves the problems of high power consumption and short service life in the existing air conditioner. The energy saver comprises a shell and an automatic control loop assembled in the shell. The invention has the technical points that a temperature acquisition control unit is arranged in the automatic control loop, and a room temperature sensor and a return air inlet temperature sensor and an air outlet temperature sensor transmit the acquired temperature analog values in three ways: the temperature analog value in the first way is converted into a digital signal through an analog-to-digital conversion chip; the temperature analog value in the second way is converted into a voltage signal through a current / voltage conversion chip of an operating mode control unit; and the temperature analog value in the third way is converted into a voltage value through a current sensor in a fault detection and recovery unit, and a pulse driver in a temperature compensation unit emits a pulse signal to drive the semiconductor refrigerator to work, thereby carrying out real-time dynamic compensation control. Due to the reasonable structural design, the invention can automatically adapt to the change of the operating state of the air conditioner, quickly display the fault, realize automatic fault recovery, obviously prolong the service life of the air conditioner and enhance the energy saving effect.

Description

technical field [0001] The invention relates to an air conditioner control device, in particular to a base station machine room air conditioner energy-saving device with functions of real-time fault detection and automatic repair. It is mainly used in communication base stations and computer rooms, especially unattended base stations and computer rooms to keep the temperature stable. It is an energy-saving control device to further improve the operating efficiency of the air conditioner and prolong the service life of the air conditioner. Background technique [0002] In order to keep the temperature of base stations and computer rooms stable, air conditioners are generally installed in existing communication base stations and computer rooms. The automatic adjustment system of existing air conditioner all adopts fixed value adjustment extensively. There is a stagnation zone in the air conditioner itself, because each compressor refrigeration system controls the start or loa...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of air conditioner energy-saving equipment in the base station computer room, which solves the problems of large power consumption and low service life of the existing air conditioner, and does not need to change the internal circuit of the air conditioner except for retaining the existing air conditioner energy-saving device, ensuring In addition to the advantages that air-conditioning manufacturers can continue to maintain the warranty, its structural design is more reasonable, it can automatically adapt to the change of the working state of the air conditioner, optimize and control quickly, real-time diagnosis of the working state of the air conditioner, quick fault display, and automatic fault repair, which is remarkable. Extend the service life of the air conditioner, improve the energy saving effect, high operating efficiency and wide application range
