PURPOSE:To improve comfortable property by a method wherein the heat exchanger of a heat pump is arranged in the underfloor of a house and cool air is circulated through the spaces of the underfloor and the rear side of ceiling so that the air is introduced into rooms when the temperature thereof becomes close to a room temperature and it has turned mild. CONSTITUTION:When the heat pump is operated to warm a condenser or an underfloor radiator 1 and a fan 1' is rotated, warm air circulation is begun. The fans 9, 10 at the rear side of the ceiling of first and second floor are operated and a damper 3 is closed, then, warm air circulates from the underfloor to a duct 11 as shown by arrow signs 2, 4, half of it flows to a passage through the arrow signs 31, 12, 12' and remain-half of it flows to the passage as shown by the arrow signs 32, 13, 13', both of them join in the passage and stair case, enter into the underfloor through the floor lattice of the passage of first floor as shown by the arrow sign 33 and sucked by the fan 1' to return to the radiator 1. Thus, warm air circulates through the whole of the spaces in the house. |
