에너지 절감형 건축물 공조관리시스템{Energy saving building air conditioning management system}Energy saving building air conditioning management system {Energy saving building air conditioning management system}

본 발명은 히트펌프를 이용한 건축물 공조관리시스템에 관한 것이다. The present invention relates to a building air conditioning management system using a heat pump.

히트펌프는 냉매가 냉매배관에 따라 순차적으로 형성된 압축기, 응축기, 팽창기, 증발기 등을 순환하면서, 열을 방출하거나 흡수하는 시스템이다.A heat pump is a system in which refrigerant circulates sequentially through a compressor, condenser, expander, and evaporator along refrigerant pipes, releasing or absorbing heat.

아래 선행기술문헌에 기재된 종래발명에도 히트펌프를 이용한 건축물 공조관리시스템이 개시되어 있다.A building air conditioning management system using a heat pump is also disclosed in the prior invention described in the prior art literature below.

종래발명의 히트펌프를 이용하여 건축물을 효율적으로 냉난방 할 수 있지만, 히트펌프의 열원으로 전기를 사용하고, 또한 히트펌프에서 에너지 소비를 절감시킬 수 있는 기술적 수단이나 구성이 효율적으로 구비되어 있지 않다.Although the heat pump of the prior invention can be used to efficiently cool and heat a building, electricity is used as a heat source for the heat pump, and technical means or configurations that can reduce energy consumption in the heat pump are not efficiently provided.

따라서, 히트펌프 작동과정에서 많은 에너지가 소비되고, 결국 지구환경에 악영향을 끼칠 수 있는 문제점이 있다.Therefore, there is a problem that a lot of energy is consumed during the operation of the heat pump, which may ultimately have a negative impact on the global environment.

일본특허공보 6345088호(2018.6.20. 공고)Japanese Patent Publication No. 6345088 (announced on June 20, 2018)

그리고, 지중케이싱 내부에 설치·회전되어, 전기 에너지를 생산할 수 있는 터빈이 설치되고, 상기 터빈의 회전에 의해, 전력이 생산될 뿐 만 아니라, 상기 터빈의 회전에 의해 와류가 발생되어, 열효율을 배가시키고, 와류에 의해 지중케이싱 내부의 공기를 건축물에 바로 공급하여, 건축물 공조관리시스템의 열효율을 높일 수 있다.In addition, a turbine is installed and rotated inside the underground casing and can produce electrical energy. Not only is power produced by the rotation of the turbine, but also a vortex is generated by the rotation of the turbine, thereby improving thermal efficiency. By doubling the amount and supplying the air inside the underground casing directly to the building through eddy currents, the thermal efficiency of the building's air conditioning management system can be increased.

그리고, 히프펌프을 기본으로 하는 냉난방장치는, 가역의 2개의 사이클에서 각각 필요로 하는 냉매량이 차이가 있는 것을 발명인은 연구과정중 알게 되었고, 냉매량은 많이 필요로 하는 사이클에 맞추어서 냉매 충진을 하고 있다. 또한, 본 발명의 히트펌프 공조 관리시스템의 경우에도, 히트펌프의 열효율을 높이기 위해서는, 난방사이클에 비해 냉방사이클의 냉매순환량이 많이 필요한 것을 본 발명인은 연구과정 중 알게 되었다.In addition, the inventor discovered during the research process that there is a difference in the amount of refrigerant required in the two reversible cycles of the heating and cooling device based on the hip pump, and the refrigerant is charged according to the cycle that requires the largest amount of refrigerant. In addition, in the case of the heat pump air conditioning management system of the present invention, the present inventor learned during the research process that in order to increase the thermal efficiency of the heat pump, a larger amount of refrigerant circulation in the cooling cycle is required than in the heating cycle.

The flexibility of the circulation pipe can be greatly improved, and the thermal insulation and corrosion resistance can be excellent even after installation in the ground, thereby doubling the thermal efficiency of the heat pump and maximizing the lifespan of the underground water circulation pipe.

그리고, 본 발명의 지중케이싱(30)은, SUS304 스테인레스 스틸로 내부케이싱과 외부케이싱과의 사이에 충진되는 황토로 이루어져서, 내식성이 우수하면서, 열효율성이 우수하고, 인간의 건강에 기여하는 친환경적인 케이싱의 제작이 가능하게 한다.In addition, the underground casing (30) of the present invention is made of SUS304 stainless steel and is made of red clay filled between the inner casing and the outer casing, and has excellent corrosion resistance, excellent thermal efficiency, and is an environmentally friendly material that contributes to human health. It makes the production of casing possible.

또는, 본 발명의 지중케이싱(30)은, 미세하게 분말가공 처리된 다수의 성분으로 된 자기 재료를 진공에서 반죽, 반죽 내부에 기포 형성을 방지하여 케이싱의 형상을 형성한 후, 2500℃ 이상의 고온에서 소성하여 고강도와 내구성 및 내수성을 갖는 지중케이싱으로 활용할 수 있다.Alternatively, the underground casing 30 of the present invention is made by kneading finely powdered magnetic material made of a number of components in a vacuum, forming the shape of the casing by preventing the formation of bubbles inside the dough, and kneading it at a high temperature of 2500°C or higher. It can be fired and used as an underground casing with high strength, durability, and water resistance.

또한, 상기와 같이 지중케이싱(30)을 친환경적인 재질인 자기(30-CE)로 제작하여, 지중공기를 보다 친환경적으로 냉각 또는 가열할 수 있다.In addition, as described above, the underground casing 30 is made of porcelain (30-CE), an environmentally friendly material, so that underground air can be cooled or heated in a more environmentally friendly manner.
