PROBLEM TO BE SOLVED: To reduce noise when a temperature control system is installed at an indoor area.SOLUTION: This temperature control system comprises a heat source machine (1) having heat pumps (3, 5, 6 and 8); a tank (16) connected to the heat source machine (1) and at the same time for storing either hot water or cold water got through a heat exchanging with the heat pumps (3, 5, 6 and 8); a cooling or heating unit (2) having a circulation pump (17) for circulating either hot water or cold water in the tank (16); heat exchanging terminals (P1 to P8) connected to the cooling or heating unit (2) where either hot water or cold water circulated by the circulation pump (17) flows; and a pump rotating speed control part (15a) for controlling the number of rotation of the circulation pump (17). The pump rotating speed control part (15a) has, as control modes, a normal mode in which the circulation pump (17) is driven under a predetermined standard rotating speed and a silent mode in which the circulation pump (17) is driven at a lower rotating speed than the standard rotating speed.SELECTED DRAWING: Figure 1 |
