HVAC HVAC CONTROL METHOD USING VAV SYSTEM FOR SHIPS

摘要

The present invention relates to an HVAC control method for a ship using a variable air volume (VAV) method. The HVAC control method for a ship using a VAV method includes a sensor to measure a temperature and an air volume in a plurality of cabins arranged in a ship, uses a plurality of dampers to open and close an opening of a cabin duct installed in a ceiling of the cabins and connected to one or more supply fans and ventilation fans to control air conditioning of individual cabins, and comprises: a step of assigning a unique identification number to each cabin; a step of receiving rank information of a first user corresponding to any one cabin among the plurality of cabins and a work time table dividing a daily schedule of the first user into work time and rest time from the first user; a step of matching the inputted rank information and work time table to the identification information corresponding to the cabin to store the rank information and the work time table; and a step of adjusting an opening degree of the damper corresponding to the cabin to allow an air volume sensed in the cabin to reach a preset minimum air volume if an arbitrary time point is in a range of the work time of the work time table matched to the cabin. Accordingly, air conditioning of each cabin is controlled to be minimally performed during work time of a crew member residing in the cabin to prevent unnecessary energy consumption to reduce energy in the ship.
