Description

technical field [0001] The invention relates to a constant temperature control system based on flow control, and more particularly relates to a constant temperature control device for solar heat utilization based on fluid flow control. It is suitable for research and application fields such as laboratories, electronics, medicine, chemicals, food processing, agricultural scientific research, and environmental protection. Background technique [0002] In the fields of medical and scientific research, especially in the research of materials, a lot of research work needs to heat and dry materials and objects under constant temperature conditions, which puts forward higher requirements for constant temperature control technology. [0003] The existing constant temperature control technology at home and abroad mainly has two implementation methods: 1. In terms of electric heating energy supply, it mainly relies on the temperature controller system PID to control the heating resist...

AI Technical Summary

Problems solved by technology

However, the above two methods have the following problems: for the first method, its application is limited to electric energy as the energy supply form; for the second method, the price of the finished product of the electric control valve is relatively high, and it is easy to cause thermal protection of the motor, deceleration, etc. The gears are easy to be damaged, the module thyristor is easy to burn out and other faults, while the self-operated control valve has the disadvantages of low adjustment accuracy, not suitable for occasions with drastic temperature changes, and the fluid viscosity cannot be too high.

However, the above methods are not only very difficult to realize, but also cause huge waste of solar energy

Existing constant temperature control technology cannot achieve accurate constant temperature control effect by using solar energy for heating under the premise of ensuring greater economic benefits
