Control method and system of heat exchange unit

Abstract

The invention provides a control method and system of a heat exchange unit, relates to the technical field of battery production, and at least solves the problems of high energy consumption, high noise, poor heat exchange effect, short service life and the like due to the fact that fans corresponding to all condensers operate at the same rotating speed in the related technology. The control method comprises the steps that based on load information, a target condenser is determined from at least two condensers; based on the external environment information, a target fan is determined from fan sets corresponding to the target condenser; and based on the current condensation temperature corresponding to the target condenser, operation of the target fan is controlled.
