method for controlling the temperature in a bioreactor.

摘要

A temperature maintaining method for a bioreactor is able to maintain constant temperature in a bioreactor (1). A hot water temperature control system (4) and a cold water temperature control system (5) are connected through a heat exchanger (3) to a circulating line for a liquid in the bioreactor (1). Control temperature L1,L2, H1 and H2 are then set, where the control temperature L1 at which the hot water temperature control system (4) becomes on, a control temperature L2 at which the cold water temperature control system (5) becomes off, a control temperature H1 at which the hot water temperature control system (4) becomes off, and a control temperature H2 at which the cold water temperature control system (5) becomes on. With this arrangement, the hot and cold water temperature control systems (4,5) are turned on and off when temperature of the liquid in the bioreactor (1) reaches these control temperatures.
