Abstract
The invention relates to a modular heat exchange unit sequential starting control system and a control method. When a conventional heat exchange unit starting control system is used for control, the temperature and the water level of a water tank and the starting and the stopping of heat exchange units are required to be manually controlled, and the phenomena of misoperation and the like and influence on control over the temperature and the water level of the water tank are easily caused by manual operation. The system comprises an expansion water tank (1), wherein the expansion water tank is connected with a heat exchange unit (2) through a pipeline; one end of the heat exchange unit is connected with a hot water tank (4) through a pipeline, and the other end of the heat exchange unit is connected with a sewage tank (3) through a pipeline; the sewage tank is connected with a variable frequency water pump (5) through a pipeline; the variable frequency water pump is connected with the expansion water tank through a pipeline. The invention provides the modular heat exchange unit sequential starting control system.
