Key tekinoroji zvinhu zvinokanganisa kugona kwesimba

Kunzwisisa Kudzoreredza Kwesimba mune inotenderera kupisa inotsinhana- Yakakosha tekinoroji zvinhu zvinokanganisa kushanda kwesimba

Masisitimu ekudzoreredza kupisa anogona kupatsanurwa muzvikamu zviviri zvichienderana neanopisa ma paramita eiyo system: masisitimu ekudzoreredza simba uye kutendeuka kubva mukupisa kwetsvina ine yakakwirira yekupisa paramita (pamusoro pe70.^oC) uye masisitimu ekudzoreredza simba uye kutendeuka kubva kumarara kupisa ane yakaderera thermal paramita (pazasi 70^oC).

Kudzosa kupisa uye simba rekushandura masisitimu pamusoro pe70^oC inoshandiswa mune tekinoroji maitiro anoitika musimba, chikafu, makemikari, uye mamwe maitiro-akavakirwa maindasitiri uko hukuru hwekupisa kupisa hunoburitswa.Uku kupisa kwetsvina ine yakakwira kupisa paramita inogona kushandiswa kuvandudza simba nehupfumi hwemabhizinesi nekudziya kwakananga mweya mumasisitimu ekufemesa kana nekuwedzera tekinoroji nzira dzinoda tembiricha yepamusoro (semuenzaniso sosi yekupisa yemapombi ekupisa anoshandiswa pasteurization muindasitiri yechikafu, kana kugadzirwa kwemagetsi mune organic Rankine Cycle kana Kalina Cycle masisitimu).Kupisa kwetsvina ine maparamendi akakwidziridzwa ekudziya anogona zvakare kushandiswa kuita firiji uye kuita mhepo inotonhorera (semuenzaniso kushandura simba rinopisa kuita mvura inotonhorera uchishandisa absorption kana adsorption chiller).

Kudzosa kupisa uye simba rekushandura masisitimu ari pasi pe70^oC anowanzo shandiswa pakudziisa muzvivakwa zvekugara (semuenzaniso kupisa kwepasi nekushandiswa kwemapombi ekupisa) kana zvivakwa zvekutengesa (semuenzaniso mumhepo inobata mayuniti (AHU) yekudziya mhepo "mutsva" kana "yekunze" nekudzoreredza kupisa kubva ku" kushandiswa. ” kana “kupedza” mweya).Ichi chinyorwa chichatarisa pane zvekutengesa kuvaka zvikumbiro.

Heat recovery systems mumhepo inobata ma units inobva pamasisitimu maviri ayo, zvichienderana nerudzi rwemhinduro yakagamuchirwa mukugadzirwa kweyuniti, inoshandisa magetsi (active systems) kana kwete (passive systems).Active heat recovery systems mumhepo inobata ma units anosanganisira, semuenzaniso, masisitimu akavakirwa pane anotenderera anopisa kupisa kana reversible kupisa pombi.Passive kupisa kudzoreredza masisitimu anosanganisira muchinjiko uye hexagonal heat exchangers.Hunhu hwekudziya kudzoreredza mumhepo masisitimu ndeyekuti kupisa kunodzoserwa pane diki tembiricha mutsauko pakati peyepamusoro tembiricha yemhepo rwizi uye yakadzika tembiricha yemhepo rwizi, uye tembiricha yepamusoro haiwanzo kudarika makumi matatu.^oC (muzvivakwa zvekutengesa, kudzoreredza kupisa kunoitika kunyangwe pakudzika kwemhepo tembiricha).

Kazhinji, kupisa kudzoreredza mumhepo yekufefetera uye mhepo-inogadzirisa zvikamu kunoitwa uchishandisa rotary kana kuyambuka-kuyerera (hexagonal) kupisa kunopisa, kashoma kushandisa kupisa pombi.Rotary heat exchangers anoshandiswa muAHUs uko kuchinjika kukuru pakati pekupinza nemhepo yekubuda muAHU inotenderwa (izvi zvinowanzova zvivakwa zveveruzhinji).Muchinjikwa-kuyerera uye hexagonal heat exchangers anoshandiswa mumhepo inobata mayuniti uko kuwanda kuchinjana pakati pemhepo yakachena uye yakashandiswa haibvumirwe (semuenzaniso zvipatara).Mapombi ekupisa anodzoreredzwa anoshandiswa kana tembiricha yakakwira inopa mweya inodiwa nekuda kwekudziya.

Misa uye simba rekuenzanisa mumagetsi ekupisa anoshandiswa mumhepo inobata zvikamu

Paunenge uchiverenga rotary heat exchanger performance yekudziya kudzoreredza mumhepo inobata mayuniti, kuwedzera kune simba chiyero, yakakodzera misa chiyero inodiwa.Izvi zvinotevera simba uye misara kuenzanisa equations ye steady-state kuyerera mamiriro ane inotevera fungidziro.Periodic parameter shanduko inokonzerwa nekutenderera kweanochinjanisa inoverengerwa musimba rose uye mwando chiyero - ndiko kuti, nguva nenguva shanduko yenzvimbo mutembiricha uye mwando pamusoro pevhiri rinotenderera hazvina kukosha uye nekudaro zvinosiiwa mukuverenga.

a) Misa, kuisa pfungwa, uye simba chiyero chezvinotenderera zvinopisa zvinopisa:
