Kusungirako-kutentha-ku-ku-mphamvu kwa PV padenga

Asayansi ku Spain awunika momwe 'mphamvu-to-heat-to-power storage' imathandizira m'nyumba yoyika dzuwa ku Madrid.Ukadaulo ukhoza kuchepetsa ngongole zamagetsi kuposa 70% ndipo ungakhale ndi nthawi yobwezera ya 12 mpaka 15, malinga ndi ofufuza.

Ofufuza a ku Polytechnic University of Madrid awunika kuthekera kwa kusunga mphamvu yopangidwa ndi sola yapadenga ngati kutentha komwe kumatha kugwiritsidwa ntchito kupanga mphamvu dzuŵa silikuwala - 'kusungira mphamvu kutenthetsa-to-mphamvu,' kapena PHPS luso.

Dongosolo lanyumba ku Madrid lomwe adaphunzira ndi asayansi limaphatikizapo njira yabwino kwambiri,pampu yotenthetsera yoyendetsedwa ndi thermallyndi osonkhanitsa matenthedwe adzuwa.

Tekinoloje ya 'trigeneration', kapena kuphatikiza kuzizira, kutentha ndi mphamvu (CCHP) imaphatikizapo mitundu iwiri yosungiramo kutentha: yotsika kapena yapakatikati yamadzi otentha am'nyumba ndi kutenthetsa malo komanso malo osungiramo kutentha kwapamwamba kophatikiza kutentha ndi mphamvu. m'badwo.Kutentha kopangidwa kale kungagwiritsidwe ntchito kuziziritsa komanso kutenthetsa kufunika.

Kalasi yowunikira idakhazikitsidwa pakugwiritsa ntchito magetsi a gridi kuphatikiza pampu yotenthetsera yoyendetsedwa ndi magetsi kuti izizizirira.

Zinthu

Gulu la Madrid linanena zinthu kuphatikizamtengo wamagetsi a gridi ndi mafutandipo mtengo ndi zokolola za PV arrays zingakhudze kukula koyenera kwa kachitidwe ka trigeneration.Ofufuzawo adayerekeza mtengo wa € 900-1,200/kW pamakina a PV ndikutengera kuyerekeza kwawo kwa phindu la PHPS pazopulumutsa magetsi.

Dongosolo losungiramo mphamvu zapanyumba zopangira mphamvu zamagetsi zimatha kuyendetsa magetsi opitilira 70%, malinga ndi ochita kafukufuku, koma angafune zaka 12-15 kuti azilipira."Izi zimakhala zowona ngakhale pamene kutembenuka kwa kutentha kwa mphamvu [kuchita bwino] kumakhala kochepa kwambiri (20-30%), pokhapokha ngati chuma chili bwino," ofufuzawo anatero.

Gulu la Madrid lidavomereza kutayika kwa kutentha m'malo osungiramo kutentha kwambiri kungatanthauze kuti dongosolo la PHPS lingatanthauze mphamvu ya dzuwa yodzipangira yokha 40-60%."Njira zomwe zingatheke zochepetsera kutayika kumeneku ndi monga kupanga zolemba zatsopano, zosungirako kutentha kwambiri pa kutentha pang'ono, kapena kusungunula kwapamwamba kwambiri [makina]," anawonjezera ofufuzawo.
