Patent number: 11796211Abstract: A constant temperature air circulation system is provided. Air valves are installed behind two three-way nodes of a main circulation loop and parallel bypasses to adjust a flowing amount of gas of each branch. When a compressor keeps a current state unchanged, a draught fan and air valves do not change. When the compressor needs to be turned on and then to be turned off, an air volume of the draught fan is adjusted, and the flowing amounts of the bypasses and a main circuit are simultaneously adjusted until the air valves that control a flowing amount of an evaporator are all closed and the air valves of the bypasses are all opened. Adjustment of the air valves and state switching of the compressor are made at the same time, so that the flowing amount flowing through a heater to a chamber is ensured to always remain unchanged.Type: GrantFiled: June 11, 2021Date of Patent: October 24, 2023Assignee: Wuhan Micro-Environment Control Technology Co., Ltd.Inventors: Xiaoping Li, Di Cao, Jianhui Wang, Jinchun Wang
