Air conditioner system and running control method and device of air conditioner system

Abstract

The invention discloses an air conditioner system and a running control method and device of the air conditioner system. A closed-loop control logic is adopted for adjusting a refrigeration mode of the air conditioner system, so that the working state of various modules can be adjusted accurately, and the energy efficiency of the air conditioner system is further improved. The running control method of the air conditioner system comprises the following specific steps: adjusting a first output rotating speed of a compressor according to an indoor first return air temperature at first, and thengradually adjusting a first fan rotating speed of a fan arranged at an evaporator; adjusting the working state of a throttling element according to a superheat degree and an evaporation temperature ofthe compressor; then, after fans arranged at the compressor and the evaporator respectively work at the first output rotating speed and a first fan rotating speed and the throttling element stably outputs under a determined working state, acquiring the condensation pressure at the compressor and an indoor second return air temperature at the moment, and determining the refrigeration required rotating speed of the compressor at the moment according to the second return air temperature; and finally, adjusting the working state of the compressor according to the condensing pressure and the refrigeration required rotating speed.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to an air-conditioning system, an operation control method and device for the air-conditioning system. Background technique [0002] The rapid development of the information industry and digital construction has promoted the rapid growth of the number and construction scale of data centers and communication base stations. According to statistics, the energy consumption of air conditioners in computer rooms and base stations accounts for about 40% to 50% of the total energy consumption. The sensible heat load of computer rooms and base stations is relatively large, and continuous cooling operation is required throughout the year. Therefore, how to improve the annual energy efficiency ratio of the air conditioner and reduce the energy consumption of the air conditioner is a technical problem to be solved urgently. [0003] In addition, the current heat dissipation sch...
