The application provides a control device and control method for powering-on / powering-off of an equipment set. The control method for the powering-on / powering-off comprises the steps that when an instruction for powering on the equipment set is received, counting will be started; and when counted time reaches preset powering-on / powering-off delay corresponding to one piece or multiple pieces of specific equipment in the equipment set, the specific equipment corresponding to the moment when the counted time reaches the powering-on / powering-off delay can be powered on / powered off. According to the scheme provided by the application, powering-on / powering-off time sequences of the specific equipment in the equipment set become adjustable; universality of the equipment set and utilization efficiency of each piece of equipment are increased; the system becomes more energy-saving; and in addition, users' demands for different powering-on / powering-off time sequences of the different equipment in the equipment set can be satisfied, and repeated development aiming at different demands is unnecessary.
Description
technical field [0001] The present application relates to the technical field of electric appliance control, and in particular to a device and method for controlling startup / shutdown of equipment units. Background technique [0002] Existing central air-conditioning units usually use a fixed sequence to control the start or stop of each device when starting or shutting down, for example, before the compressor is turned on, the start and stop of chilled water pumps, cooling water pumps, cooling tower fans, etc. The control usually adopts a fixed set of timing. When the unit is powered on, the chilled water pump is turned on first, and then the cooling water pump is turned on after the chilled water pump is turned on, and then the cooling tower fan is turned on after a delay. In the prior art, it is only possible to change the delay start or stop time of each equipment of the air conditioning unit through the parameter setting of the display terminal, but the order of each eq...
