SYSTEM FOR CENTRALLY HEATING AND AIR CONDITIONING ENTIRE BUILDING USING GEOTHERMAL HEAT

摘要

PROBLEM TO BE SOLVED: To solve such a problem that conventional house air conditioning has demerits in cost, the labor of construction and energy consumption since a plurality of air conditioners are installed in units of individual rooms, or the conventional air conditioning takes much labor for constructing duct piping since air is sent from a single air conditioner to the individual rooms through the duct piping, and the conventional air conditioning generally has a high initial cost and a high energy consumption.;SOLUTION: Cool air and warm air generated by an air conditioner are sent using the underfloor space of a first floor to each room, so that the number of air conditioners is reduced and construction labor is saved. Additionally, geothermal heat of a small depth is sent to an upper floor such as a second floor, so that power consumption of the air conditioner of the first floor can be reduced and the labor of installation and construction of equipment is saved. An initial cost (equipment and construction labor) is therefore reduced, and electric power consumption is remarkably reduced to contribute to energy saving since the single air conditioner and natural energy of the geothermal heat are used.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2016,JPO&INPIT
