[Patent Document 1] JP-A-200-289533 [Patent Document 2] JP-A-2003-20 71 74 SUMMARY OF INVENTION [Problems to be Solved by the Invention] Boiler, in the above heat exchanger , because the boiling water machine (and chiller) is not used, the running cost can be reduced.

2098-7382-PF 5 1310076 The source is getting tighter and therefore requires more energy savings. However, in order to obtain the necessary heat in the above-described underground heat exchanger, it is necessary to excavate the vertical pit for a long time in a deep portion by a special excavating machine. In order to prevent the collapse of the vertical pit, it is necessary to post-treat the excavated mud too. There will be a problem that the number of work items is too large and the manufacturing cost is increased. At least the manufacturing cost is reduced, and the capacity of the U-shaped earth-bottom rail exchanger inserted into the κ-pit is increased, and the policy of inserting a plurality of U-shaped ground-bottoms is used. However, in the narrow range of the underground, the number of collections is concentrated. = During the winter season, since the volume per unit volume taken from the underground soil is increased, the recovery of the underground temperature takes a long time, and the amount of picking decreases: However, the operation of the air conditioner cannot be continued, or it is necessary to use an anti-liquid that prevents the junction from being caused by environmental pollution. Further, in the U-shaped underground heat exchanger, since the superheated medium flows in the same path as the forward path and the re-route, for example, during the winter season, the return of the hot medium to the valley, the heat release from the hot heat medium will generate a large amount. The problem of heat loss is not limited to this. The purpose of the present invention is to provide a bottom heat exchanger and a heat pump type air conditioner using geothermal heat, which can suppress the manufacturing cost and can be used. Inhibition of heat loss. [Means for Solving the Problem] In order to achieve the above object, the underground heat exchanger of the first invention is characterized in that it can be buried in the ground, and the heat of the heat medium of the long η# can be exchanged with the soil. The sentence includes: •, 々 Α 4 g g °卩' is spiral, the above heat medium is

The heat pump type air conditioner using the geothermal heat according to the invention of the third aspect of the present invention, wherein the name is the same as that of the water supply side heat exchanger and the water coil The heat transfer tube is an elliptical tube. <Twelfth, the present invention relates to a geothermal heat-dissipating air-conditioning apparatus characterized in that, in the invention of the above-mentioned water heat source heat pump and the water Ig, the passage of the conduit is connected Air supply fan unit. According to the first aspect of the invention, the pipe portion is tapered and has a long spiral shape and is buried in the vicinity of the earth's surface. By causing the heat medium to flow back to the geothermal flow, the heat exchange efficiency is improved, and the ground is dispersed over a wide range and surrounding the soil. Do a heat exchange. Thereby, in order to adjust the temperature of the heat medium to obtain the necessary amount of heat, the amount of heat per unit volume obtained from the soil may be good. In general, the temperature of the ground to a depth of 1 meter is affected by the external air, a _; Li low and summer. However, the temperature difference between the heat medium (winter) or the heat release (summer) depends on the soil in the ground, and the temperature of the π soil in the ground is easy to recover. 'Long-term continuous air conditioning operation is possible J. Continuous heating - even if you use no environmental pollution, q water will not freeze 2098-7382-PF 8 1310076 knot, no need to use high-priced non-leaching. Moreover, since the road Α s is formed in a spiral shape and is easy to process, the structure of the spring is flexible, so that it has excellent vibration-proof property, and it is sufficient for earthquakes to prevent leakage of heat due to breakage. . On the other hand, the road management department only respects the shackles, and the media returns to the ground, no matter how long or short, and then crosses the ground with _ Μ ϋ 4σ <4· η . ', , the heat exchange of the 乂 change is less, and the temperature of the heat medium is stabilized by the heat exchange efficiency. In addition, it is possible to reduce the excavation time and reduce the cost by using the excavation of the ordinary excavator (power_shovel) or the like. According to the second aspect of the invention, the spiraling diameter of the spiral pipe portion is changed to be larger than the heat exchange region of the escaping pipe portion, so that heat exchange is not distributed over a wide range of the ground, and the bottom temperature is desired. Early reply, so that the hot father change efficiency. For example, when the coil diameter is sequentially expanded downward to form a pipe line, the heat transfer amount is increased by increasing the diameter of the forward pipe portion 1 as the depth of the bottom pipe portion is increased. Further, in the case where the road pipe portion is buried, the shape of the hill formed by the shape of the pipe from the diameter of the central portion to the pipe portion can be buried without breaking the shape of the pipe portion. On the other hand, when the diameter of the spiral is gradually reduced to form the pipe portion, the hole for the embedding is formed into a mortar shape in accordance with the shape thereof, and construction is easier. According to the third aspect of the invention, the heat transfer medium can be dispersed in a wide range by the spiral shape of a circle, an ellipse or a polygon, and the temperature of the ground can be easily recovered by dispersing the heat generation. Further, when the road pipe portion is a polygon such as an ellipse or a rectangle, it can be easily buried in a land having a narrow length of 2098-7382-PF 9 1310076. According to the fourth invention, the pipe portion is made thinner, and the field is caused to sneak around the squadron. At the same time, the heat medium is induced downward and the shape is changed from t, and Φ is formed into a shape that can be arranged at a predetermined interval. Cheng-to-pair (two) to the road management department. Through the shape of the pipe portion, the heat medium is reversed with respect to the geothermal flow, whereby the exchange rate of the crucible is changed, and the ground is dispersed over a wide range for heat exchange. Thereby, the temperature of the heat medium can be adjusted to obtain the necessary amount of ground heat. The amount of heat per unit volume obtained from the ground soil can be reduced. One is protected by a eve version, and the ground temperature at a depth of 1 meter is high in winter and low in summer due to external air. However, the temperature difference due to heat medium heating (during winter) or exothermic (during summer) corresponds to the underground bottom temperature being easy to recover, allowing for long-term continuous air conditioning operation. Further, since heat can be continuously extracted, water having no environmental pollution can be used as a heat medium without freezing, and it is not necessary to use an expensive antifreeze. Further, in the pipe portion, the heat medium is serpentine inside and has a shape that can flow downward, and has a spring-like elasticity, which is sufficient for the durability of the earthquake, and can prevent leakage of the heat medium due to breakage. On the other hand, as long as the heat recovery medium can return the heat medium to the surface, the length can be shortened, and /, the heat exchange of the soil of the ground can be reduced, and the heat loss is reduced by the heat exchange rate k. stable. In addition, it is sufficient to perform shallow excavation near the surface of the earth with a general excavation machine such as a single bucket excavator, which is sufficient for the excavation time to reduce the cost. Further, the two road sections are opposed to each other and the width of both is narrowed, whereby the land can be easily buried in a narrow and slender land. According to the fifth invention, each time the road pipe portion extends downward, a pair of roads

2098-7382-PF 10 1310076

The distance between the pipe sections changes 'avoiding the heat exchange zone between the pipe sections'. It is not necessary to fill the entire range of the ground to exchange heat, so that the underground temperature can be recovered early, and the efficiency of heat exchange can be improved. For example, when the distance between the two is sequentially expanded downward to form the road pipe portion, when the road pipe portion is buried, the soil is piled up from the vicinity of the intermediate portion, and the hill is formed along the shape of the pipe portion. The shape can be buried without damaging the shape of the pipe portion. On the other hand, when the distance between the two is narrowed downward to form the forward pipe portion, the shape of the hole can be formed into a v-groove shape in accordance with the shape thereof, and construction can be facilitated. According to the sixth aspect of the invention, the forward pipe portion is flat, and the heat transfer rate of the heat medium flowing in the central portion of the pipe is increased, and the heat exchange efficiency can be further improved. Further, since the flat tube is easily bent, the forward tube portion can be easily processed into a spiral shape or a serpentine shape. According to the seventh aspect of the invention, the duct portion is a flat tube, and the long-diameter side end portion of the cross-section has a pointed shape, so that the heat medium flowing inside is likely to generate turbulent flow, and the convection is forced to promote heat transfer, thereby improving heat exchange efficiency.

According to the eighth aspect of the invention, the pipe portion is a round pipe, and the cross section of the pipe wall is wavy. The turbulent flow of the heat medium flowing inside is more ", and the heat exchange can be performed. The efficiency is even higher.

According to the ninth invention, the water source heat pump is used to cool or heat the air supply air to a set temperature, and the water coil:: the air supply air (four) source heat pump load or cool down. By this, it can reduce the heat of the water and save energy by reducing the load. Also, in the cold and what period, only the water supply air is cooled by the water coil, and the water is hot.

2098-7382-PF 11 1310076 The source heat system does not need to be operated, and can expect more energy-saving effects. " Moreover, the pipe section becomes thinner and the long pipe is snaked in the left and right direction, and at the same time, the pipe line is matched with two = shape to form a pair of geothermal flows at a predetermined interval for countercurrent flow...::: Compared with the surrounding area, the efficiency is better and the ground is scattered in the vast range of ::: hot father. By this, because of the heat of the heat medium?
