(PERMEABLE HEATPUMP SYSTEM WITH EASY INSTALLATION AND OBJECT REMOVAL) < RTI ID = 0.0 >

More particularly, the present invention relates to a tubular heat pump system, and more particularly, to a system for forming a tube in a rock layer, a casing installed inside the tube to allow groundwater to flow into the casing, Exchanged water is supplied to a heat pump through a heart pump to be used as a heat source for heating and cooling the heat pump, and the foreign matter adhered to the magnetization of the tube If the flow rate is reduced to less than 80% due to clogging of the pipeline, it is necessary to remove compressed air or high-pressure water or compressed air and high-pressure water to the magnetized sludge to remove foreign matter. The present invention relates to a pipe-type heat pump system that is easy to operate.

The temperature difference energy is a system that can be used for cooling, heating, and hot water supply.

Since the temperature difference energy can not be directly used, it is used through heat exchange with a heat source such as a heat pump or a freezer. Systems using heat pumps are common to both sea water, surface water (lake) and sewage treatment water.

The temperature difference energy is less than the atmospheric temperature change in the atmosphere. The highest temperature in summer is lower than the maximum temperature, so it is suitable as the cooling water of the heat pump. It is more efficient than the heat sink by using the cooling tower generally used. It is higher than the maximum temperature and is used as the heat source of the heat pump, and the efficiency of the heat pump is better than that of using air.

Therefore, when the temperature difference energy is used as a heat source for heating the evaporator of the heat pump in the winter season and as a cooling heat source for the condenser in the summer season, the hot and cold heat is produced with high efficiency as compared with the heat pump (EHP etc.) .

Compared with the existing heating and cooling system, the energy saving of the temperature difference energy, that is, the unused energy, is expected to be water, the improvement of the urban and global environment, and the power leveling effect. Compared with conventional heating and cooling systems, the amount of carbon dioxide can be reduced by 40 ~ 60% and the production of NOx by 60 ~ 80%.

In addition, surface water and surface water, which are temperature difference energy, have abundant amount unlike other heat sources. Therefore, it is expected that the heat pump system using temperature difference energy as a heat source will be increased along with development of utilization technology.

However, there are technical problems such as the recovery of heat in actual use of unused energy, and various technical problems that can apply such unused energy are required.

In order to meet such a demand, the present applicant has filed and registered with the Korean Patent Registration No. 10-1055350 (a conventional type heat pump system).

The foreign matter removing unit 117 is provided with a plurality of discharge holes 117a on the side surface desirable. Here, the foreign substance removing means 119 is a high-pressure pump for discharging compressed air or high-pressure water for discharging compressed air. In addition, filter saris (soybean gravel) can be filled between the outer casing 111 and the inner casing 113.

The heartbeat pump 120 is installed at the end of the water discharge pipe 115 to supply the groundwater collected in the tube 110 to the heat pump 130. At this time, the installation position of the heartbeat pump 120 is located at the lower end of the water level of the collected groundwater, and the administrator can adjust the position using a separate position adjusting device (not shown).

However, in such a conventional tubular heat pump system, when a crack occurs at the upper portion of the inflow hole due to an external impact when the internal casing is installed, water flows through the cracks and is immediately discharged through the heart pump. There is a problem that actual cooling or heating is not performed.
