AI Technical Summary
Existing temperature control units have poor cooling and heat dissipation capabilities in biopharmaceutical applications, affecting the accuracy of temperature control.
The system adopts a structural design that includes a first cycle, a second cycle, and a third cycle. Temperature control is achieved through a liquid storage heating tank, the second cycle removes the heat from the first cycle, and the third cycle removes the heat from the second cycle. Combined with an evaporator and a condenser, temperature control is achieved, thereby improving the cooling and heat dissipation function.
While possessing a heating function, it effectively improves the accuracy of temperature control and ensures the temperature stability of the bioreactor.
