Description

Information communication system for geothermal heating and cooling management

The present invention relates to an information communication system for geothermal heating and cooling management, and more particularly to an information communication system for geothermal heating and cooling management based on information communication technology (ICT).

Most commonly used energy sources are fossil fuels such as coal, petroleum, natural gas, or nuclear fuels. However, fossil fuels pollute the environment due to various pollutants generated during the combustion process, and nuclear fuels generate harmful substances such as water pollution and radioactivity, and these energy sources have a limited amount of reserves.

Therefore, in recent years, the development of alternative energy to replace this has been actively progressed. Among these alternative energies, researches on natural energy such as wind, solar, geothermal, etc. have been conducted for a long time and practically installed air conditioning and heating system using them. These natural energies have almost no influence on environmental pollution and climate change. While there is an advantage in obtaining energy, it is a key factor in the development of natural energy technology to increase the density and convert it into a usable form due to the drawback of very low energy density.

One of such natural energy technologies is known as a heat pump system that performs cooling and heating using geothermal heat as a heat source.

Geothermal heat pump system is a technology that uses a heat exchanger to heat the ground heat of 10 ~ 20 ℃ or discharge heat into the ground to use as a heat source of the heat pump.

In general, as a heat source of a heat pump, an air heat source method for obtaining or discharging heat in the atmosphere, such as an air conditioner, and a water heat source method for discharging heat through a cooling tower are used. The use of geothermal sources has the advantage that the energy efficiency is very high compared to air heat sources.

In particular, the year-round air temperature in the region where the four seasons are obviously changed greatly is -20 ~ 40 ℃, while the underground temperature is almost constant at 10 ~ 20 ℃ throughout the year below 5m underground.

Therefore, in the case of cooling in summer, the air heat source temperature is consumed a lot of power to discharge the cooling heat to 30 ℃ or more, while the geothermal heat source is smoothly discharged to 10 ~ 20 ℃ shows a high efficiency. On the contrary, in the case of heating in winter, the air heat source is difficult to supply the heat necessary for heating at the lowest temperature of -20 ° C, while the underground heat source is 10 to 20 ° C, which can stably supply the heating heat to the heat pump.

The geothermal heat pump system is known to have the highest energy efficiency among all air-conditioning technologies. Therefore, it is an essential technology in a situation where energy resources are scarce and energy costs are high.

On the other hand, the conventional geothermal heat pump system is formed of a structure in which the heat medium introduced from the outside stays in the ground for a longer time in order to increase the heat exchange efficiency of the fluid.

For example, the conventional geothermal heat pump system is formed in a spiral heat exchanger buried in the ground to circulate the fluid so that the heat medium flowing from the outside stays in the ground for a longer time.

However, the heat exchanger having such a structure is not easy to manufacture substantially, the shape of the heat exchanger is deformed due to its own weight, there was a problem that the installation is not easy in the ground.

In addition, the conventional heat pump system is driven through a manual operation, after the user checks the temperature of the room one by one, and heat exchanges the fluid through the heat exchanger until the temperature of the room to the appropriate temperature. Therefore, when it is necessary to constantly maintain the room temperature at a constant temperature, the operator had to inconvenience monitoring the room temperature and controlling the heat pump system continuously.

Meanwhile, as the heat exchanger applied to the conventional heat pump system is manufactured to a predetermined standard, the fluid always passes through a predetermined path during heat exchange of the fluid.

However, when the heat exchanger described above is manufactured to a too short length, the heat pump system must be operated for a long time to maintain the heat exchanged fluid at a set temperature, and when the heat exchanger is manufactured to a too long length, the heat exchanged fluid is a heat pump. There was a problem that it takes a long time to return to the unit.

In addition, the control server 140 is a difference value (a) between the set temperature stored in the database 142 and the room temperature of the building (S) is less than -3, or greater than 3 (-3≥a, 3 ≤a) A third control command may be generated and transmitted to the relay device 130. The relay device 130 transmits the control command transmitted from the control server 140 to the underground heat exchanger 120 (S180), and the underground heat exchanger 120 according to the control command transmitted through the relay device 130. The movement path of the fluid is varied (S190).

Thus, according to an embodiment of the present invention, by combining the information communication technology in the building (S) and the underground heat exchanger 120, the user can monitor the room temperature of the building (S) in real time even at a location away from the building (S). Of course, the underground heat exchanger 120 can be controlled remotely to continuously maintain the indoor temperature of the building (S) in a constant state.

In addition, by providing a plurality of heat exchange units (121, 122, 123) that can be connected in the longitudinal direction, it is easy to manufacture and install, and can be assembled in various lengths according to the conditions of the ground can increase the usability.

In addition, depending on the indoor temperature of the building (S) or the temperature of the ground (G), the plurality of heat exchange units (121, 122, 123) connected to each other selectively communicate with each other, it is possible to change the movement path of the fluid, The heat exchange efficiency of the fluid can be maximized.
