Title:
HEAT SOURCE SYSTEM, CONTROL METHOD THERFOR, AND PROGRAM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/096265
Kind Code:
A1
Abstract:
Provided is a heat source system for which the system COP is improved without reducing the operating efficiency of the cold source; also provided are a control method therefor and a program therefor.
This heat source system (N1) is one for which pumps (P, P3) which transmit a heating medium to a cold source (R) that cools the heating medium and/or to a heat exchanger that exchanges heat between the cooled heating medium and a load (1), and the cold source (R), and a heat exchanger for the load (1), are connected by pipes (r1, r2) through which the heating medium flows. The heat source system has: load heat amount measurement means (3, 4) that measure the amount of heat which the heating medium exchanges with the load (1); a cooling water circulation temperature measurement means (4) that measures the temperature of the heating medium (R) that exchanges heat with the load (1) and returns to the cold source; and a first control means (2) that lowers the temperature setting for the heating medium at the outlet of the cold source (R) when temperature of the heating medium falls below the temperature setting therefor and the difference with respect to the temperature setting for the heating medium at the outlet of the cold source (R) becomes less than a prescribed amount.
