<p><P>PROBLEM TO BE SOLVED: To provide a hot water heat supply system and the like capable of efficiently supplying water into the system without using power of a high-pressure pump and the like. <P>SOLUTION: This hot water heat supply system comprising a hot water boiler producing the water of a prescribed temperature higher than 100°C, a heat supply device for supplying the heat of the water supplied from the hot water boiler to the external, a water circulating passage for circulating the water between the hot water boiler and the heat supply device, a bypass passage for mixing a part of the water cooled by providing heat in the heat supply device with the water supplied from the hot water boiler, a pressure-resistant container receiving the water supplied from the hot water boiler before mixed with a part of the water providing heat in the heat supply device to keep the water supplied from the hot water boiler to the heat supply device under a saturated steam pressure at the prescribed temperature, and a hydrate vaporizer for pressurizing the vaporized water produced by vaporizing hydrate by a gas produced by vaporizing hydrate of water hardly-soluble gas, and pressure-feeding the same to the circulation passage, is sealed up. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
