Abstract

PURPOSE:To prevent the freezing thereof by circulating a heat medium when the temperature is low. CONSTITUTION:A heat radiator 1 and a heat source machine 2 are connected by a heat medium circulating pipe 3, having a heat medium circulating pump 4 and an electromagnetic valve 5 and the electromagnetic valve 5 is being opened through a manual switch when the freezing is expected. A freeze preventing thermostat 9 is closed and the pump 4 is operated to circulate the heat medium when the temperature is low.
