<p>PURPOSE:To reduce noise of a heatpump system for cooling/warming having an engine arranged in a liquid tank by employing a hollow cover and providing an air-cleaner element in the inner space. CONSTITUTION:A liquid tank 2 is contained in an outer tube opening upward while an engine 3 is arranged in the heat medium water W in the liquid tank 2. A pipe P provided in spiral on the innercircumferential face of said tank 2 is coupled to the external hot-water supplier or a warmer. An exhaust heat exchanger 10 and an exhaust silencer 12 are provided below the cylinder head 8. A flange 33 is fixed to the upper end of a flywheel housing 23 and a working machine 31 is fixed to the flange 33. Said flange 33 is supported through a vibration-isolating rubber 42. The outercircumference of an annular cover 47 is fitted to the upper end of the outer tube 1 while the interior is made hollow to arrange an intake silencer 55 having an air-cleaner element 77.</p> |
