Abstract
The invention discloses a liquid circulation control system for communicated containers. The liquid circulation control system for communicated containers adopts circulating hydraulic pressure of two ice water machines to conduct linkage control, so as to enable circulating liquids at two different temperatures to have the same pressure in the interior of the two cavities that are communicated by capillary tubes. The state of pressure balance enables the two circulating liquids to be in a dynamic isolation state (the two circulating liquids do not circulate in the capillary tubes or the flowing quantity is reduced); the temperatures of the two circulating liquids are controlled, circulating fluid storage tanks are further prevented from overflow caused by excessive liquid or machine halt caused by excessively insufficient liquid. The manufacturing cost is reduced and the working efficiency is improved.
