화석연료는 현대사회의 주요 에너지원이지만 CO2 배출로 인한 지구온난화와 기후변화의 중요한 원인이기도 하다. 2022년 전 세계 CO2 배출량은 36.8 기가톤으로 사상 최고치를 기록했다. 전 세계 국가들은 CO2 배출량을 줄이고 이를 산업화 이전 수준으로 유지하기 위해 노력하고 있다. 이에 우리나라는 화력발전을 완전히 중단하고 탄소배출량을 줄이는 등 탄소중립을 달성하기 위해 노력하고 있다. 농업 부문에서는 2018년 대비 탄소 배출량을 37.7% 줄이겠다는 목표를 세웠다. 한국의 대부분 농장은 온실 난방에 화석 연료를 사용한다. 이에 따라 농업부문에서도 온실가스 가열을 위한 화석연료의 대안으로 재생에너지를 활용하려는 관심이 높아지고 있다. 반면, 멜론은 다른 작물에 비해 성장에 더 높은 온도가 필요한 내열성 작물이며, 겨울에 온실에서 재배되는데 겨울철 난방을 위해 상당한 화석 연료가 필요한다. 따라서 멜론의 재배를 위하여 신재생에너지를 활용 화석연료의 소비를 줄일 필요가 있다. 상기와 같은 문제를 해결하고자, 여름 또는 겨울의 온실의 난방부하를 계산하는 작기난방부하 계산단계; 및 상기 작기 난방부하 계산단계에서 계산된 난방부하에 상기 작기 동안에 태양열 난방시스템에서 부담할 수 있는 냉난방�

Embodiments of a solar table mobile transport vehicle capable of carrying multiple solar tables are described. Multiple solar tables may be vertically stacked on a rack. Each solar table may be supported by a pair of cantilevered beams such that the solar table may be unloaded from the rack in an unobstructed manner. The rack may be loaded on a mobile transport vehicle for transportation to a point of installation. Solar tables in the rack may be fetched by the mobile transport vehicle or another installation rover for installation. Such a capability of carrying multiple solar tables increases the installation efficiency of solar tables, especially for large solar farm constructions.

THERMOSYPHON SOLAR WATER HEATER WITH AUTOMATIC BACKFLUSH

Absstract of: WO2025153320A1

A thermosyphon solar hot water heating system specifically designed such that it incorporates an integral, automatic backflush configuration. When hot water is drawn from the system, an automatic backflush valve redirects cold "mains" water through the system's solar collector(s) in a flow direction that is opposite to the normal buoyancy-driven flow direction that occurs during solar heating (i.e., "charging"). This backflushing action is completed passively when heated water is consumed for domestic use and does not require other user intervention. The routine introduction of cold water through the solar collector during the backflush, reduces the formation of mineral deposits in the solar collector's flow passages and the reverse flow scours the interior surfaces of the solar collector's flow channels such that the potential of scaling is significantly reduced.

A technique for recovering power from data center waste heat involves an organic Rankine cycle which includes pumping an organic working fluid through a low-temperature preheater chamber configured to exchange relatively low-temperature waste heat from low-temperature data storage devices to the organic working fluid flowing through the preheater chamber, pumping the working fluid through a high-temperature evaporator thermally coupled with the preheater chamber and configured to exchange relatively high-temperature waste heat from high-temperature CPUs to the working fluid flowing through the evaporator, and pumping the working fluid vapor from the evaporator to an expander for generating power via expansion of the working fluid. The preheater and evaporator may be directly incorporated with the enclosure box housing the various heat-generating components.
