PURPOSE:To reduce a mechanical noise and suction and exhaust noise, by providing an engine in the inside of a storage water tank filled with a heat medium and coating a driven equipment, containing a mounting part of the engine, by a soundproof case. CONSTITUTION:A storage water tank 1 is constituted by the main unit 2 of a tank filled with a heat medium in the inside and a cover member 5 water-tightly fitted through a vibro-isolating material 3 and a seal material 4. An engine 11 immersed in the heat medium is mounted to a bottom face of the cover member 5. While a compressor 13, being an equipment as driven by the engine 11 further coating the external part by a soundproof case 12, is mounted to an upper face of the cover member 5. In such way, a noise of the engine 11 and the compressor 13 can be decreased, further a noise arising from mechanical vibration can be reduced. |
