Title:
A heat supply control device, a heat distribution system, and a heat supply control method
Document Type and Number:
Japanese Patent JP6033674
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heat supply system and a method for reducing the total power consumption of a pump of each supply plant, in a system constituted of a plurality of plants and a plurality of customers.SOLUTION: The number of revolutions at which the power consumption of the pump of each heat supply plant becomes minimum is calculated by using a primary-side necessary flow rate of a heat exchanger of each customer building, a pressure loss equitation, a pump lift curve equitation, and a flow-rate preservation formula, the pump whose increase amount of the power consumption is small with respect to an increase of the number of revolutions is controlled according to a valve opening of the customer building, the pump of the other heat supply plant is controlled with the calculated number of revolutions as a target value, and heat supply is performed.
