Description

Open cooling and heating and cool and hot water system using ground source

The present invention relates to an open air-conditioning and cold / hot water generation system using a geothermal source, and more particularly, to produce hot water and cold water simultaneously as a geothermal source, and to enable heating and cooling as the produced hot / cold water so that the hot water can be cooled. If the temperature does not reach a certain range when the geothermal source is still used in the heat pump, the pumped groundwater is discharged to the outside. If the geothermal source temperature is above a certain temperature, about 80% of the ground is excavated. Discharged to the bottom area, and the remaining 20% of the pumped groundwater is discharged to the upper ground area so that the discharged groundwater is absorbed evenly above and below the excavation site. Open air-conditioning and heating using geothermal sources to facilitate the use of geothermal sources It relates to a cold and hot water generation system.

In general, groundwater refers to water flowing below the surface of the earth, and the outer surface of the earth is covered with rocky crust, and water flows through the rock just below the ground where plants grow. Most groundwater is formed by the gathering of rain and snow melts that seep into the soil. When water reaches the rock, it flows through open gaps between the rocks. The speed of groundwater flow is not constant depending on the environment of the underground, so in some places it flows about 1.5m per day, but some groundwater flows very slowly at an average speed of about 1.5m per year.

In addition, underground heat means that about 47% of solar heat is stored underground through the surface, which is 500% of the amount of energy we use. Such underground heat is free from pollution, can be continuously charged naturally, and can use about 400% of the energy saved during the hot summer during the winter, and most of the energy currently used depends on the generation power. By contrast, it can produce about 48% energy efficiency, and in the case of gas or oil, it can produce around 36% to 43% of heat, but when using underground heat, it can produce about 75% of heat.

Therefore, when the groundwater is discharged to the ground surface, it absorbs the above-mentioned underground heat, and a number of devices that can cool and heat the groundwater heat source by moving the groundwater heat source to the heat pump system by using the groundwater heat source that absorbed the ground heat by underground excavation have been proposed. have.

In the system where cooling and heating is performed by moving the groundwater heat source in the heat pump as described above, the groundwater is moved by the heat pump during heating to absorb and heat the heat source included in the groundwater, and the groundwater from which the heat source is removed is again underground. On the contrary, during cooling, the ground water is moved from the heat pump to absorb the cooling heat source included in the ground water to cool the ground water, and the ground water from which the cooling heat source is removed is moved back to the ground.

Thus, in the conventional system that can move and heat the groundwater heat source by the heat pump system, the cooling and cooling efficiency can be obtained when the amount of groundwater is large, but the groundwater heat source is insufficient when operated under the same conditions in the place where the groundwater is low. This does not move the required heat source in the heat pump is a problem that can not be cooled and heated.

In addition, in the conventional heating and cooling system using a geothermal source, it is possible to produce cold water and hot water, but to produce cold water during cooling. Only the hot water production is used for heating. However, there is no system for producing hot and cold water at the same time. In case of a business that requires hot water, there is a problem that a separate hot water supply device must be installed.

In addition, if the groundwater contains calcite, the calcification generates scale in the heat exchanger, which drastically decreases the heat exchange efficiency and lifespan, and if the groundwater is located near the sea and contains chlorine, (Salt) component is a problem that all the components of the heat pump system corrosion is fast progressed significantly shortening the life of the system.

The present invention is to produce the hot water and cold water at the same time by using the ground water as a heat source in order to solve the above problems to make the heating and cooling as the produced cold and hot water, as well as to enable the use of hot water at all times, the production The technical problem is to provide an open-type hot and cold water tank that can accumulate the hot and cold water is used to prevent the heat pump is frequently stopped when the cooling and heating space is small during the heating and cooling.

In addition, the present invention is to discharge the pumped ground water to the outside when the temperature of the geothermal source in the heat pump does not reach a certain temperature range to increase the efficiency in the production of hot and cold water, and the cooling and heating water circulates in the underground drilling site when not discharged As groundwater is polluted at the time of discharge, it solves the groundwater pollution problem because it discharges externally.When the temperature of geothermal source is over a certain temperature, about 80% is discharged to the bottom of the underground excavation site and the remaining 20% of the pumped groundwater is underground By discharging to the upper area, the discharged groundwater is absorbed evenly above and below the excavation site so that the geothermal source does not reach the required temperature range and the discharged groundwater is absorbed evenly if the cooling and heating efficiency drops. If the cooling and heating efficiency is lowered because the required temperature is not reached, the discharged groundwater is discharged to the outside. It is a technical problem to be able to absorb underground heat evenly.

In addition, the present invention prevents the generation of scale due to the calcification when the groundwater is contained in the open-cold water tank, corrosion even when the groundwater is located close to the sea containing chlorine (saline) component Does not occur, and the heat exchanger composed of `` S '' type zigzag shape is installed to maintain the residence time of the heat exchange medium and increase the surface area, which not only increases heat exchange efficiency and contributes to fuel saving, but also improves the life of the heat pump system. It is technical problem to be able to extend.

Figure 2a is a block diagram showing another embodiment of the open-type heating and cooling and hot and cold water generation system using a geothermal source according to the present invention, Figure 2b is a cross-sectional view of the open-type cold and hot water storage tank shown in Figure 2a, the open-type cold and hot water storage A heat and heat exchanger module having two heat exchangers connected in series to each of the tanks 12 and 13 in parallel to allow the circulating water circulated through the cooling and heating passages 17 and 18 to pass through the heat exchanger module. The water stored in (12) (13) is used as a heat exchange medium.

That is, each of the two types of 'S' type zigzag shape is formed in the open cold water storage tank 12 such that the residence time of the heat exchange medium is kept long and the surface area is increased, so that the efficiency of heat exchange is high, as shown in the cross-sectional view shown in FIG. 2B.
