<p>PURPOSE:To contrive to save heating energy and permit to establish freely an installing condition on location and operating hours by a method wherein a heating temperature required for floor heating is obtained from 2-steps of the temperature increase by arrangement of 2-stages of heat pumps, while, a well water is utilized as a heating source. CONSTITUTION:The heat pump of the first stage A and the same of the second stage B are comprise evaporators 1A, 1B, absorbers 2A, 2B, heat generators 3A, 3B, and condensers 4A, 4B. As a concentrated heating source of sulfuric acid in the heat generator 3A for the heat pump in the first stage A, the well water 13 near by the building is utilized. And hot waters obtained indirectly from heat exchanging with sulfuric acid solution in the absorber 2A and or the same solution flowing out from the absorber 2A to the heat generator 3A, is utilized as the heating source for evaporating in the absorption type heat pump (B) of the second stage and for the concentrated heating source of a sulfuric acid in the heat generator 3B. The hot water obtained from the second stage of the absorption type heat pump B, are actuated for the floor heater 35.</p> |
