\t\t\t\t\t\tIn the\u00a0low temperature\u00a0chiller system, the electronic expansion valve plays a key role in controlling the operating power of the system in cooperation with compressors, condensers, evaporators, water-cooled screw chillers, air-cooled screw chillers, cryogenic screw chillers, central air-conditioning units, chillers, water-cooled chillers and air-cooled chillers. Its operation situation will determine the\u00a0practical\u00a0refrigeration ability and control accuracy\u00a0of the\u00a0low temperature\u00a0chiller system. However, most chillers use electronic expansion valves or thermal expansion valves as a saving arrangement\u00a0of system.\u00a0Controlling\u00a0the superheat of the compressor inlet\u00a0is most primary. However, due to the positioning in this planning, the electronic expansion valve can not fully exert\u00a0the control efficacy\u00a0of system accuracy. During the operation of low<\/strong> temperature<\/strong> K\u00e4ltesystem<\/strong><\/a>, control can complete the optimal output control of system cooling capacity, but as is always the case, it can\u2019t be completely exerted to\u00a0output control system cooling capacity when the temperature is close to the equipment policy. the accuracy of the system\u00a0can\u2019t be ensured. Although the precision has been improved when using the method of PID control, as a whole, there is still a lot of room for improvement. <\/p>\n

Equipment and Planning of Electronic Expansion Valve
\nIn\u00a0the low temperature\u00a0chiller system, the electronic expansion valve is generally used as a general saving arrangement to control the superheat of compressor. It is usually equipped between the evaporator inlet and the\u00a0condenser outlet. According to the superheat of compressor inlet, the size of the adjustable opening is analyzed and judged in real time, and the optimal control of superheat is completed to reach the optimal output of system cooling capacity. However, when the control\u00a0needs to be accurate , due to the constraints of superheat, the best ability of refrigeration output control is often not brought into play, and the system temperature control accuracy is poor. <\/p>","protected":false},"excerpt":{"rendered":"
