<p>PURPOSE:To make it possible to perform a heating operation which is comfortable and healthy to the human body by a method wherein a floor heating unit and an indoor cooling unit are operated side by side at the time of heating operation. CONSTITUTION:The floor heating unit A having a floor heat exchanger 1, a heat exchanger for cooling, the indoor cooling unit B haveing a blower 3 and an outdoor unit C having heat exchangers 5 and 8 which consitute a cooling cycle by connecting the units A and B are provided and the units A and B are operated side by side at the time of heating operation. That is, cool air blown out by the blower 3 is so adjusted that it is blown out toward the space between the ceiling and one's head at the time of heating operation. Thus, when the heating operation is started, hot air flows along the surface of the floor while the cool air flows along the ceiling so that a head cooling and foot warming heating operation which is pleasant and healthy to the human body can be performed. Further, it is possible to collect heat generating in the space which does not serve to warm the human body and to utilize such heat effectively by radiating it from the surface of the floor so that the efficiency of the entire system is improved to a remarkable degree.</p> |
