The present invention relates to a geothermal shrinkage heat type heat pump system that enables air-conditioning using geothermal heat. Cold water is stored at 5 ° C. in summer in a shrinkage heat tank that is stratified using midnight power, and 50-55 hot water in winter. The present invention relates to a regenerative heat pump system for improving and stabilizing thermal bridge performance with a geothermal system by separately installing a geothermal shrinkage heat tank having a stratification between a heat and cooling heat pump and a geothermal system.
히트펌프는 압축기, 응축기, 증발기, 팽창밸브로 구성된 냉동사이클를 총칭하는 용어로 사용되어 왔으나, 종래에는 냉동사이클을 이용하여 냉방과 난방이 가능한 시스템을 히트펌프라 하는 것이 보편화 되어 있다. 대표적인 히트펌프는 우리가 많이 사용하는 에어컨이다.
The heat pump has been used as a generic term for a refrigeration cycle composed of a compressor, a condenser, an evaporator, and an expansion valve, but in the related art, it is common to use a refrigeration cycle to heat pump a system capable of cooling and heating. A typical heat pump is an air conditioner that we use a lot.
이러한 냉방기능이 있는 히트펌프에 주위의 폐열이나 공기열원, 태양열을 열원으로 확보하여 난방 기능으로 사용 가능하게 하여 발전시켜 나가고 있는 상황이 현재의 상황이다.
The current situation is that the heat pump having the cooling function is developed by making the surrounding waste heat, air heat source, and solar heat source as a heat source to be used as a heating function.
이러한 히트펌프 시스템은 사용자측과 히트펌프 사이에 직접 연결하거나, 작은 용량의 탱크를 설치하여 사용하므로 주변 여건에 민감하게 반응하고 히트펌프의 잦은 on/off로 히트펌프의 효율을 감소시킬 뿐만 아니라 문제 발생시 사용자측에게 많은 고통을 수반하게 하였다. 또한 여러 가지 열원중 선택한 열원이, 겨울철 냉매 와 증발기에서 열교환하여 난방으로 운전될 때에도 열원의 상황 변동에 따라 히트펌프의 성능이 갑작스럽게 저하되는 불안 요소를 가지고 있었다.
Since the heat pump system is directly connected between the user side and the heat pump or by installing a small capacity tank, the heat pump system reacts sensitively to the surrounding conditions and reduces the efficiency of the heat pump due to frequent on / off of the heat pump. It caused a lot of pain on the user side. In addition, the heat source selected from the various heat sources had anxiety factor that suddenly degraded the performance of the heat pump according to the change of the heat source even when operating by heating by heat exchange in the refrigerant and evaporator in winter.
본 발명의 종래기술인 지열을 이용한 냉난방 시스템의 경우에도 히트펌프의 열교환기(증발기,응축기)와 지열 시스템이 바로 열교환하므로 효율 및 이상발생시 대처 능력에 문제가 있고, 사용자측의 사용율에 따라 운전하므로, 운전비가 상승하여 사용자에게 어려움을 발생시킬 수 있다.
In the case of a conventional heating and cooling system using geothermal heat, the heat exchanger (evaporator, condenser) of the heat pump and the geothermal system directly exchange heat, so there is a problem in efficiency and handling ability when an abnormality occurs, and it operates according to the usage rate of the user. Rain may rise and cause difficulties for the user.
본 발명은 지열을 이용하여 냉난방이 가능하게 하는 지열 수축열식 히트펌프 시스템에 관한 것으로 심야 전력을 이용하여 성층화를 이룬 수축열 탱크에 여름철에는 냉수를 5℃로 저장하고, 겨울철에는 온수를 50~55℃ 저장하여The present invention relates to a geothermal shrinkage heat type heat pump system that enables air-conditioning using geothermal heat. Cold water is stored at 5 ° C. in summer in a shrinkage heat tank that is stratified using midnight power, and 50-55 hot water in winter. ℃ storage
첫째, 사용자가 원하는 냉수와 온수의 온도를 조절하여 사용할 수 있게 하고,First, to allow the user to adjust the temperature of the cold and hot water you want,
둘째, 사용자가 원하는 냉수와 온수량을 냉동기 용량과 상관없이 보다 자유롭게 사용할 수 있는 편리함을 제공한다 Second, it provides convenience that users can freely use the amount of cold water and hot water they want regardless of the freezer capacity.
냉난방용 히트펌프와 성층화를 이룬 지열 시스템 사이에 지열용 수축열 탱크를 별도로 설치하여 A geothermal shrinkage heat tank is installed separately between the heating and cooling heat pump and the stratified geothermal system.
첫째, 지중의 온도변화에 따른 히트펌프의 성능 감소를, 지열 수축열탱크가 완충작용을 하므로 갑작스러운 사태에 대비할 수 있고 예방할 수 있다. First, the performance reduction of the heat pump due to the change in the ground temperature, the geothermal shrinkage heat tank buffers against the sudden situation can be prepared and prevented.
둘째, 난방시 지열 수축열 탱크 하부의 물을 5℃로 일정하게 유지하여 지열 시스템에 공급하므로 열교환효율을 향상 시킬 수 있다.Second, the heat of the geothermal shrinkage heat tank at the bottom of the heating at 5 ℃ to maintain a constant supply to the geothermal system can improve heat exchange efficiency.
셋째, 냉방 운전시 냉온수 수축열조에는 냉수를 저장하고 , 지열 수축열조에는 사용가능한 온수를 저장하므로 냉수와 온수를 동시에 사용할 수 있다.Third, cold water is stored in the cold and hot water shrinkage heat bath during the cooling operation, and hot water is stored in the geothermal shrinkage heat bath, so cold water and hot water can be used simultaneously.
넷째, 온수 저장 온도를 일반 냉각수 온도보다 높게(40~55℃) 유지하므로 지열 시스템(15~25℃)과의 온도차가 크므로 여름철 열교환 효율을 향상 시킬 수 있다.Fourth, since the hot water storage temperature is maintained higher than the normal cooling water temperature (40 ~ 55 ℃), the temperature difference with the geothermal system (15 ~ 25 ℃) can be improved in summer heat exchange efficiency.
또한, 응축수 온도 상승에 따른 히트펌프의 성능 감소를 성층화를 이룬 지열수축열탱크의 하부물을 일정하게 공급하여 예방할 수 있다.
In addition, it is possible to prevent the decrease in the performance of the heat pump according to the rise of the condensate temperature by constantly supplying the bottom of the geothermal heat storage tank stratified.
상기와 같이 본 발명은 기존 지열 시스템과 구분되는 성층화를 이룬 냉온수용 축열탱크와 성층화를 이룬 지열용 축열탱크를 이용한 축열식 히트펌프 시스템에 관한 것이다.
As described above, the present invention relates to a heat storage type heat pump system using a heat storage tank for cold and hot water, which is stratified from a conventional geothermal system, and a heat storage tank for geothermal heat.
