HOT WATER SUPPLIER UTILIZING SOLAR HEAT

摘要

PURPOSE:To prevent the change of radiant heat quantity from a collector or the like in keeping with the change of quantity of insolation, feed water temperature and outside temperature and keep hot water temperature constant by a method wherein the quantity of discharging hot water is controlled in accordance with the temperature of the hot water leaving the collector. CONSTITUTION:The inlet 11 of a hot water storage tank 7 is connected through a flow controller 14 to the discharging hot water port 3 of the collector 1 equipped with a heat collecting tube 4 therewithin and with a feed water port 2 and the discharging hot water port 3 at the lower and upper ends thereof. The flow controller 14 is actuated by the output of a hot water temperature detector 15 arranged at the discharging hot water port 3 so as to control the quantity of discharging hot water in response to the temperature of the hot water leaving the collector 1.
