The present invention relates to an air conditioning apparatus using underground air. More specifically, the underground air suction pipe is connected to an external air suction duct of the air conditioning unit, but the underground air suction pipe is formed in a porous layer formed of a gravel layer, pine stone, etc. which are not affected by external air. By laying up to the ground, it is related to an air conditioner using underground air to perform humidification or dehumidification as well as cooling and heating by naturally increasing or decreasing absolute humidity according to seasons by using warm underground air in winter and cool underground air in summer.

In general, the building is provided with an air conditioning system for cooling and heating as well as humidity control as necessary to live in a pleasant atmosphere throughout the four seasons (四 季節), which is shown in FIG.

Here, the heating coil 12 heated by the boiler 11 to dissipate heat, and the cooling coil 14 supplied with the refrigerant by the freezer 13 to absorb and heat the surrounding heat to cool the air filter 15 as well. ), A baffle (16), a humidifying spray (17), an eliminator (eliminator) 18, and a blower (19) form one air conditioning unit (10).

The air conditioning unit 10 connects the blower duct 21 with the blower 19 up to the building 20 to be air-conditioned and connects the blower 24 from the building 20 to the air conditioning unit 10. The return duct 23 is connected, and the return duct 23 is provided with a return or exhaust control dampers 25 and 26 for adjusting the return air volume and the exhaust air volume, and the air conditioning unit 10 is provided with the return duct 23. The outside air suction duct 27 for introducing the outside air into the air conditioning unit 10 is provided, and the outside air suction duct 27 is provided with an inflow control damper 28 for controlling the outside air inflow flow rate.

Existing air conditioner configured as described above, when operating the boiler 11 in the low temperature and low humidity, the heat is emitted from the heating coil 12, the heat is operated by the blower 19 through the blower duct 21 Supply to the building 20 to perform a predetermined heating. At this time, when the humidity is low, the humidifying spray 17 may be operated to maintain a comfortable atmosphere in life by supplying proper moisture.

When the air in the building 20 continues to be turbid as described above, the ventilator 24 of the return duct 23 is operated to recover a part of the air to the air conditioning unit 10 through the return duct 23 and the rest of the air. Can be discharged to the outside. At this time, the amount to be recovered to the air conditioning unit 10 and the rest is discharged to the outside while the return control of the return duct 23 or the exhaust control dampers (25, 26) while appropriately adjusting the inflow control damper (27) Adjust (28) to control the inflow air flow.

On the contrary, when the air blower 19 is operated in a state in which the refrigerator 13 is operated to absorb and heat the surrounding heat in the cooling coil 14 during the summer when the temperature is high and humid, the cold air is blown through the air duct 21 Cooling the air in the building 20 through and also dehumidification in the cooling coil 14 while lowering the absolute humidity to maintain a comfortable environment in life. At this time, water droplets form around the cooling coil 14 of the air conditioning unit 10, which is removed by the eliminator 18.

Thus, even during cooling, the air in the building 20 is recovered to the air conditioning unit 10 and the rest is discharged to the outside, and the adjustment thereof is the same as mentioned above, and thus the detailed description thereof will be omitted.

However, in the conventional air conditioner as described above, since the air is cooled and heated by simply inhaling the outside air, the humidification spray 17 or the elimination when the heating coil 12 and the cooling coil 14 of the air conditioning unit 10 are operated. There is a problem that the air conditioner unit 10 becomes complicated because the humidifier 18 must be operated essentially, and thus the air-conditioning unit 10 must be provided with the humidification spray 17 and the eliminator 18. .

In particular, due to the flying yellow dust generated in China during the spring season, not only serious air pollution but also various infectious diseases are occurring throughout the Republic of Korea, and these air pollution have to be filtered by the air filter (15). Of course, the replacement of the air filter 15 as well as to replace the air conditioning unit (10) was a fundamental problem that can not solve the pollution problem of the air conditioning unit 10.

The present invention has been researched and developed in order to solve the conventional problems as described above, the purpose is to connect the underground air suction pipe to the outside air suction duct of the air conditioning unit, but the underground air suction pipe is not affected by the outside air to gravel layer, pine stone, etc. By laying up to the formed porous layer, it is relatively warm compared to outside air in winter and cool air is heated by humidification or dehumidification by increasing or decreasing absolute humidity naturally according to season using underground air that is relatively cool compared to outside air in summer. Accordingly, the present invention provides an air conditioner using underground air to reduce the capacity of the boiler and the refrigerator by eliminating the refrigerator and its cooling coil, as well as the boiler and its heating coil, or minimizing its operation time.

In addition, another object of the present invention is to prevent the collapse of the underground porous layer and increase the underground air suction area by inserting and pressurizing the underground air suction pipe whose bottom is cut in the longitudinal direction into the underground drilling hole to expand the lower part of the underground air suction pipe into a sphere. It is to provide an air conditioning apparatus using underground air.

Another object of the present invention is to provide an air vent in the upper part of the building, when the air blower of the air conditioning unit is opened and exhausted and closed when stopped, thereby allowing underground air in the building to be naturally ventilated even if the fan is not operated. To provide an air conditioning apparatus using.

The present invention for achieving the above object includes a heating coil that is heated by a boiler to dissipate heat, and a cooling coil that receives a refrigerant by a freezer to absorb heat around and cools the air, as well as an air filter and a blower. One air conditioning unit is provided, and the air conditioning unit connects the blow duct to the blower to the building to be air-conditioned, and the return duct is connected to the air conditioning unit from the building to the return duct, and the return duct and the exhaust air flow rate to the return duct. In the air conditioning unit is provided with a return or exhaust control damper for controlling the air, the air conditioning unit is provided with an external air suction duct having an external air inlet control damper, the external air suction duct to the gravel layer, pine stone, etc. are not affected by the outside air Underground air intake pipes are buried up to the formed porous layer.

In the air conditioner of the present invention, the underground air suction pipe is inserted into the underground excavation hole and pressurized from the upper side, so that the lower part of the underground air suction pipe can be easily expanded into a spherical shape, and a plurality of long grooves in the longitudinal direction are provided in the lower part. . In addition, the end of the cutting groove may be formed in the groove in the circumferential direction of the underground air suction pipe to expand more easily.

In the air conditioner of the present invention, the building is provided with a ventilation opening so that the blower of the air conditioning unit is opened and exhausted and closed when stopped. It features.

Hereinafter, the air conditioner using the underground air of the present invention will be described in detail based on the accompanying drawings.

2 is a schematic configuration diagram of an air conditioning apparatus using underground air according to the present invention, Figure 3 is a structural diagram showing in detail the main portion of the air conditioning apparatus of the present invention, Figure 4 is the air in the air conditioning apparatus of the present invention A structural diagram showing another embodiment of the suction pipe.

As shown in the figure, the air conditioner according to the present invention is a heating coil 12 that is heated by the boiler 11 to dissipate heat, and a cooling unit supplied with a refrigerant by the freezer 13 to absorb heat around and cool it. As well as the coil 14, the air filter 15, the baffle 16, the humidification spray 17, the eliminator 18, and the blower 19 form one air conditioning unit 10.

The air conditioning unit 10 connects the blower duct 21 with the blower 19 up to the building 20 to be air-conditioned and connects the blower 24 from the building 20 to the air conditioning unit 10. The return duct 23 is connected, and the return duct 23 is provided with return or exhaust control dampers 25 and 26 for adjusting the return air volume and the exhaust air volume.

The air conditioning unit 10 is provided with an outside air suction duct 27 having an outside air inlet control damper 28, and the underground air suction pipe 30 is connected to the outside air suction duct 27. ) Is artificially provided in the basement of the depth not affected by the outside air, or buried up to the porous layer 40 formed of a naturally made gravel layer, pine stone and the like.

When the underground air suction pipe 30 is inserted into the underground excavation hole and pressurized, a plurality of cutout grooves 31 long in the longitudinal direction are formed in the lower part so that the lower portion of the underground air suction pipe 30 can be easily expanded in a spherical shape. .

In addition, the base air suction pipe 30 may be formed in the groove 32 in the circumferential direction of the base air suction pipe 30 to be more easily extended to the end of the cutting groove 31 as shown in FIG. At the inner surface of the underground air suction pipe 30 in which the cutout groove 31 is formed, it is necessary to provide a structure or pay attention to prevent the underground air suction pipe 30 from being bent into the inside when pressurized from the top. Since the groove 32 is formed in the cutting groove 31 of the underground air suction pipe 30 as described above, the cutting groove 31 is easily expanded into a spherical shape larger than the diameter of the underground air suction pipe 30. In addition to preventing the collapse of the gravel layer, it is possible to increase the suction area of the underground air.

The building 20 is provided with a ventilation opening 40 which is opened and exhausted when the blower 19 of the air conditioning unit 10 is operated and closed when stopped. The ventilation opening 40 has a horizontal exhaust port 41 and the horizontal exhaust port ( 41 is composed of a damper 43, which is simply suspended vertically through the hinge 42 at the end.

The air conditioning apparatus using the underground air according to the present invention configured as described above operates the boiler 11 in winter when the humidity is low and the temperature is low. When the boiler 11 of the air conditioning unit 10 is operated in this way, heat is emitted from the heating coil 12 by steam or heating water supplied from the boiler 11, and when heat is emitted from the heating coil 12. By operating the blower 19, the hot air is supplied to the building 20 through the air blowing duct 21, whereby the cold air (temperature 0 ~ 10 ??) in the building 20 is heated to perform the heating.

Opening the outside air inlet control damper 28 of the outside air intake duct 27 while heating as described above is relatively lower than the underground air in the underground gravel layer, that is, 14 to 16 ?? and the relative humidity is about 100%. Warm underground air is supplied to the air conditioning unit 10 through the underground air suction pipe (30). Since the underground air relatively warmer than the outside air is supplied to the heating coil 12, it can be easily increased to a predetermined heating temperature and the load of the boiler 11 can be minimized.

In this way, the building 20 can be easily warmed to minimize the operating time of the boiler 11, and in a weather where the temperature is not so high, the heating is sufficiently performed even without operating the boiler 11.

In this way, while the heating is continued, the operation of the ventilator 24 is not necessary and the damper 43 of the ventilation port 40 is opened around the hinge 42 to stop the operation of the ventilator 24. When the air in the air 20 is exhausted and it is determined that the air in the building 20 is too cloudy, the ventilator 24 of the return duct 23 is operated to air-condition a part of the air through the return duct 23. The unit 10 may be recovered and the rest may be discharged to the outside. At this time, the amount to be recovered to the air conditioning unit 10 and the rest is discharged to the outside while the return control of the return duct 23 or the exhaust control dampers (25, 26) while appropriately adjusting the inflow control damper (27) By adjusting (28), the amount of inflow air from outside air may also be adjusted.

On the contrary, during the summer when the temperature is high and humid, the refrigerator 13 is operated. The blower 19 is in a state in which the refrigerant or cold water supplied from the refrigerator 13 absorbs and cools the heat around the cooling coil 14. Since the cold air around the cooling coil 14 passes through the blowing duct 21 to cool the air in the building 20 and lowers the absolute humidity according to the temperature to maintain a comfortable environment for living. At this time, water droplets are formed around the cooling coil 14 of the air conditioning unit 10, which is removed by the eliminator 18.

In this way, if the air inflow control damper 28 of the air intake duct 27 is opened during cooling, the underground air intake pipe (underground air in the underground gravel layer having a relative humidity of about 14 to 16 ° and 100% relative humidity) is always used. It is supplied to the air conditioning unit 10 through 30 and then supplied to the building 20 through the air blowing duct (21).

Since the underground air relatively cooler than the outside air is supplied to the cooling coil 14, it can be easily lowered to a predetermined cooling temperature and the load of the refrigerator 13 can be minimized. As a result, it is possible to easily lower the temperature inside the building 20 bar to minimize the operating time of the freezer 13 and in the warm weather is sufficient cooling is achieved even without operating the freezer (13).

Thus, even during cooling, the air in the building 20 is recovered to the air conditioning unit 10 and the rest is discharged to the outside, and the adjustment thereof is the same as mentioned above, so the detailed description thereof will be omitted.

As described in detail above, the air conditioner using the underground air of the present invention by connecting the underground air suction pipe to the outdoor air suction duct of the air conditioning unit by embedding the underground air suction pipe to the underground porous layer not affected by the outdoor air Humidity or dehumidification as well as humidification or dehumidification are carried out by naturally increasing or decreasing the absolute humidity according to the season using warm underground air in summer and cool underground air in summer. It is a useful design that can reduce the capacity of boilers and freezers by eliminating them or minimizing their uptime.

In addition, the present invention is to insert the underground air suction pipe cut in the longitudinal direction in the underground drilling hole and then pressurized to expand the lower part of the underground air suction pipe into a sphere to prevent the collapse of the underground layer and increase the underground air suction area. It works.

And another object of the present invention is to provide a vent in the upper part of the building to open and exhaust when the air conditioning unit blower is closed and closed when stopped, ventilation in the building even when the operation of the ventilator stops because the operation of the fan is not required It is a natural effect and has a unique effect of preventing cold air or hot air from entering the building during the winter season.
