DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air-conditioning refrigeration system for recovering underground waste heat and hot water.

[0002]

2. Description of the Related Art At present, well-known exhaust heat systems such as coolers, air conditioners, and freezers are roughly classified into two types. That is, a water-cooled type and an air-cooled type. The air-cooled type discharges the discharged heat into the atmosphere, but the specific heat of air is low, so the speed of discharging heat is low, the temperature of the condenser is high, the consumption of electricity is large, and the cooling effect is not good. . In addition, it causes noise, heat pollution, and pollution. Further, since the heat-removal capacity of the central cooling system of a building is insufficient, such a heat-removal method is suitable only for a small window-type cooler.

A water-cooling system is applied to a building air conditioning system. In the water-cooling system, hot water absorbed by a condenser is pressurized, pumped to a cooling tower on the rooftop, exhausted by air, and then sent back to the condenser again. Endothermic. Since it is repeatedly used in this manner, it is actually an indirect air cooling system. Therefore, in hot and humid weather, the temperature of the water after cooling approaches the temperature, the cooling effect gradually decreases, and complicated facilities, noise, heat pollution, pollution and the like still exist. In particular, it is used in each floor and in each room, so starting it forces the entire building to use it and wastes energy.

[0004]

In view of this, the inventor of the present invention has been working diligently to develop an air-conditioning refrigeration system having a good cooling effect by making use of his experience of designing and manufacturing coolers for many years. After repeated experiments, they finally produced the underground waste heat hot water recovery air conditioning and refrigeration system of the present invention.

An object of the present invention is to provide an underground exhaust hot water recovery air-conditioning refrigeration system which is hardly affected by ambient temperature and can perform heat exchange efficiently.

[0006]

For this purpose, an underground exhaust hot water recovery air-conditioning refrigeration system according to the present invention is provided on the roof of a building, is divided into an upper tank and a lower tank, and a water supply device is provided between them. A cooling tank is extended to the bottom of the lower tank, and a water supply pipe is extended to the upper tank,

[0007]

According to the air-conditioning refrigeration system of the present invention, cooling water serving as a medium for heat exchange is cooled underground, so that it can be efficiently cooled without being affected by the ambient temperature. become.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the air-conditioning refrigeration system for collecting underground waste heat and hot water according to the present invention basically includes a water supply tank 1 provided on a rooftop, and the water supply tank 1 is divided into a lower tank 11 and an upper tank 12 which are separated. The water tank pump 13 and a water level controller of the water supply device 14, for example, a spherical float are provided between them. That is, when the water level falls to the lower limit, the water in the upper tank 12 flows into the lower tank 11 and is replenished. This automatic water supply device is a well-known device, such as a toilet water tank.

On one wall of the lower tank 11 and the upper tank 12, a lower tank exhaust hole 111 and an upper tank exhaust hole 121 for exhaust are respectively opened. In addition, a launch pipe 122 used for supplying water is extended at the upper end of the upper tank 12. A cooling pipe 2 extends on the bottom wall of the lower tank 11, and the cooling pipe 2
Are connected to the condensers of the coolers 3 with cooling branch pipes 21 respectively, and the cooling water is sent to the recovery pipe 4 after absorbing heat.

The recovery pipe 4 is concentrated from a recovery branch pipe 41. In order to use the cooling water that has absorbed the heat flowing therein, a water pipe 42 is additionally provided, and the water pipe 43 is used to control the water pipe 42. A collecting water tank 5 is provided downstream of the main pipe of the collecting pipe 4, and a collecting tank exhaust hole 51 used for exhaust is provided on one wall of the collecting water tank 5.

A cooling pipe 6 is connected to the bottom of the collecting water tank 5 and the cooling pipe 6 is formed by coiling a corrosive-resistant pipe and burying it in the ground. The collected water enters the cooling water tank 7 through the cooling pipe 6, and the cooling water tank 7 is also provided with a cooling water tank exhaust hole 71 for exhaust. Cooling water tank 7
A pumping device 8 is extended therein, and the pumping device 8 is mainly composed of a water supply pipe 81 and a pumping pump 82 for automatically controlling the water level, and one end of the water supply pipe 81 is connected to the lower tank 11 to lower the temperature. The cooled water is sent to the lower tank 11 with the pumping device 8 and is used for circulation.

Therefore, when the present invention is carried out, it flows into the condenser of the cooler depending on the flowing direction of the cooling water,
Since it is known that the hot water has absorbed heat, it is used for washing, bathing and the like as internal warm water by opening the curan. If not used, the hot water flows into the recovery water tank, the temperature is lowered to the underground temperature by passing through the underground cooling pipe, flows again into the cooling water tank, is sent to the lower tank by the pumping device, and is used for recirculation Is done.

[0013] If the cooling water is reduced through use of the circulating curran, fresh water flows from the upper tank and is replenished. Therefore, if the present invention is implemented, the temperature of the underground is a constant temperature not exceeding 15 ° C., so that when the cooling water passes through the cooling pipe, the temperature of the water in the cooling water tank is reduced to, for example, a maximum of 20 ° C. It has a remarkable cooling effect when used for water.

What is disclosed in the present invention is an example of an optimal embodiment. All local changes or modifications that can be easily guessed based on the technical idea of the present invention and those who are familiar with the technology are included in the patent scope of the present invention.

As described above, according to the air-conditioning refrigeration system of the present invention, the purpose, means, and function are all different from those of the known cooling system, and are affected by the ambient temperature. In addition, since the heat exchange of the cooling water can be performed, the cooling performance can be greatly improved.
