[Abstract]:With the rapid development of electronic information technology, the size of electronic components is becoming smaller and smaller, and the integrated density and working frequency of chips are increasing, which leads to the characteristics of high power and high heat flux in modern computer. As the key part of computer environment control, the reliability, stability and energy saving of high performance computer-specific air conditioning and refrigeration system are paid more and more attention. According to the requirement of all-weather temperature control of a high performance computer, the design and research of special air conditioning and refrigeration system for computer are carried out. This paper introduces the development background and design basis of computer special air conditioning, investigates the application environment, technical requirements, structure characteristics and heat load status of the application object, which provides the basis for the design and optimization of the air conditioning system. According to the actual overall design requirements, combined with the widely used design methods at home and abroad, the airflow organization scheme of horizontal air supply in the closed cabinet is optimized, and the airflow field in the closed cabinet is simulated by using ANSYS software. According to the characteristics of the design object, the design scheme of using three refrigerating compressors, "dual-use one standby" and rotating operation is put forward. Based on the calculation of the parameters, the compressor is selected scientifically and the design size and structure of the evaporator and condenser are determined. The research shows that the design scheme is especially suitable for the all-weather temperature control of high performance computer, which can achieve high reliability and stability, and make energy efficient utilization, energy saving and consumption reduction, and save the user's running cost.
