である。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-efficiency / energy-saving air conditioner / hot water supply method and apparatus for using the wastewater generated in an individual house or an apartment house as an air conditioner and a hot water supply heat source for a house or various heat consuming facilities. It is a suggestion.

Description of the Related Art Conventionally, fossil fuels such as coal and petroleum are usually used as a heat source for an air conditioner / hot water supply device in a heat consuming facility. However, with the recent depletion of fossil fuels and the increase in exhaust gas that affects the global environment, such as carbon dioxide emitted from the combustion of these fuels, there is a strong demand for heat sources to replace fossil fuels. .

いう報告もある。On the other hand, recently, an air conditioning and hot water supply system using a heat pump using air or ground heat as a heat source has been developed and its introduction is promoted. This system has attracted attention because it can use unused energy that has not been used until now, such as geothermal heat, as a heat source, and, unlike conventional boiler systems, it is a clean energy system that does not rely on combustion. It has been reported that the introduction of CO2 can reduce carbon dioxide emissions by about 70-80% compared to gas or kerosene boilers.

である。However, the heat pump used under the prior art has a tendency that the amount of heat supplied is easily influenced by the amount of heat source water and temperature fluctuations. For example, when air is used as a heat source, the amount of heat recovery varies greatly due to changes in the temperature of the air, which makes it difficult to stably obtain a highly efficient operating state. On the other hand, when underground heat is used as the heat source,
Since there is almost no change in the temperature of the underground heat throughout the year, a highly efficient operating state can be stably obtained. There are two main methods for extracting this underground heat. A method of excavating a heat extraction well and circulating a medium such as antifreeze to obtain only underground heat. This is a method of excavating a water well and obtaining heat from the pumped groundwater.

問題点があった。However, in the above method, when the required amount of heat is large, it is necessary to excavate a large number of wells of several tens to several hundreds of meters, which requires a wide excavation area to some extent and a large amount of cost. There was a problem that was required. In addition, the above method has high efficiency of heat extraction from groundwater, so if a large amount of groundwater can be obtained from a small number of wells,
Although the problem of the above method can be solved, there is a problem that the place where a large amount of groundwater is actually obtained is limited to a small number.
