Air conditioning system and air conditioning system operation control method and device

Abstract

The invention discloses an air conditioning system and an air conditioning system operation control method and device. The annual energy efficiency ratio of the air conditioning system is improved, energy consumption of the air conditioning system is reduced, the indoor water leakage problem of the air conditioning system is solved, and the working reliability of the air conditioning system is improved. The air conditioning system includes a first dividing wall type heat exchanger, a second dividing wall type heat exchanger, a third dividing wall type heat exchanger, a compressor circulation loop, a pump circulation loop, a first cooling water circulation loop and a second cooling water circulation loop, wherein the compressor circulation loop includes a compressor, the hot side of the first dividing wall type heat exchanger, a flow control device and the cold side of the second dividing wall type heat exchanger which are connected with one another sequentially in a closed-loop mode; the pump circulation loop comprises a liquid storage device, a first liquid pump, an indoor unit, the hot side of the third dividing wall type heat exchanger and the hot side of the second dividing wall type heat exchanger which are connected with one another sequentially in a closed-loop mode; and the first cooling water circulation loop and the second cooling water circulation loop can be selected to be opened and closed, the first cooling water circulation loop includes the cold side of the first dividing wall type heat exchanger, and the second cooling water circulation loop includes the cold side of the third dividing wall type heat exchanger.

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 computer rooms 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 most commonly used he...
