<p><P>PROBLEM TO BE SOLVED: To provide a roof structure for melting snow which is a snow melting device of a roof by hot air circulation in winter and is used as a hot water supply device using solar heat in summer and is a heater for preventing icicle with high heat efficiency and further saves energy. <P>SOLUTION: A heat exchanger with a blower is installed in an attic space and air in the attic is changed to hot air. The hot air is blown from a blowoff port toward eaves, and circulates and melts snow while heating components. In summer air in the attic heated by solar heat is changed to hot water by the heat exchanger to be used in the hot water supply. A far infrared radiation heater is installed in an arabesque member to prevent generation of icicle. A whole roof is divided into halves at a rafter and used as an air duct. The energy-saving snow melting roof enables hot air to circulate through the upper half as a ridge path and the lower half as a returning path. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
