The invention provides a high-accuracy multi-zone temperature control system. At least one carbon fiber heating device is arranged in each space; an adjusting space is divided into a plurality of zones; a carbon fiber heat supply network in each zone is connected with a corresponding temperature control adjuster; and at least one temperature sensing probe is distributed in each zone, and is connected with a corresponding temperature control adjuster of the zone. The invention further provides a high-accuracy multi-zone temperature control method. Each temperature sensing probe acquires temperature information in each zone and feeds back the temperature information to the corresponding temperature control adjuster; each carbon fiber heat supply network heats above air purified by an air conditioner box according to a command of each temperature control adjuster; and a one-way air flow with required temperature is obtained and is sent to a corresponding area. According to the high-accuracy multi-zone temperature control system provided by the invention, the temperature adjustability of each zone in the space is realized, zoning temperature control and maintaining can be realized under the condition of different loads in the space, the temperature adjustment is more accurate, reliable and energy-saving, and the heating efficiency and the stability are improved.

technical field [0001] The invention relates to a temperature control system, in particular to a high-precision multi-zone temperature control system. Background technique [0002] Carbon fiber is a pure black body material. In the process of electricity and heat conversion, visible light is very small, and the efficiency of electrothermal conversion is over 95%. The heat loss in the heat transfer process is small, which saves energy. The heat radiation of carbon fiber is high, which can improve the design directional heat radiation. Due to its porous characteristics, carbon fiber can achieve uniform heating of the air passing through the heating device. [0003] At present, the high-precision temperature control required in the space is generally realized by precision air conditioners. Most precision air conditioners use electric heating devices. The airflow near the heating wire is heated to a high degree, and the airflow between the two heating wires is heated to a low d...

[0003] At present, the high-precision temperature control required in the space is generally realized by precision air conditioners. Most precision air conditioners use electric heating devices. The airflow near the heating wire is heated to a high degree, and the airflow between the two heating wires is heated to a low degree. The unevenness of the airflow sent out is uneven

[0004] With the development of science and technology, the temperature requirements of the process production workshop are becoming more and more accurate. Due to the large space of the workshop, the functions of each area are different, and the uneven distribution of heat production results in different loads in each area. It is difficult for existing precision air conditioners to achieve high temperature in each area. Precision Temperature Control Requirements
