Isimiso sokusebenza samaphampu okushisa ezindaweni ezibandayo
Iphampu yokushisa yomthombo womoya iwuhlobo oluvame kakhulu lobuchwepheshe bephampu yokushisa.Lawa masistimu asebenzisa umoya we-ambient ovela ngaphandle kwesakhiwo njengomthombo wokushisa noma irediyetha.
Iphampu yokushisa isebenza kumodi yokupholisa isebenzisa inqubo efanayo neye-air conditioning.Kodwa kumodi yokushisa, uhlelo lusebenzisa umoya wangaphandle ukushisa isiqandisi.Iphampu yokushisa icindezela isiqandisi ukuze sikhiqize igesi eshisa kakhulu.Amandla ashisayo ahamba ngaphakathi kwesakhiwo futhi akhishwe ngamayunithi angaphakathi (noma ngamasistimu amapayipi, kuye ngesakhiwo sohlelo).
Iphampu lokushisa endaweni ebandayo izokugcina ufudumele ubusika bonke.
Lapho isiqandisi siphansi kakhulu kunokushisa kwangaphandle, iphampu yokushisa inikeza ukushisa okuthembekile.Esimweni sezulu esipholile, amaphampu okushisa ezindaweni ezibandayo angasebenza ngempumelelo efinyelela ku-400% - ngamanye amazwi, akhiqiza amandla aphindwe kane amandla asetshenzisiwe.
Yiqiniso, lapho kubanda kakhulu, kuba nzima nakakhulu ukuthi iphampu yokushisa isebenze ukunikeza ukushisa.Ngaphansi komkhawulo othile wokushisa, ukusebenza kahle kwesistimu kuzokwehla.Kodwa lokhu akusho ukuthi amaphampu okushisa awafanele amazinga okushisa angaphansi kwendawo yokuqandisa.
Amaphampu okushisa kwesimo sezulu esibandayo (owaziwa nangokuthi amaphampu okushisa asezingeni eliphansi) anezici ezintsha eziwenza akwazi ukusebenza kahle emazingeni okushisa angaphansi kuka-30 degree.Le misebenzi ihlanganisa:
Isiqandisi sezulu esibandayo
Wonke amaphampu okushisa omthombo womoya aqukethe isiqandisi, inhlanganisela ebanda kakhulu kunomoya wangaphandle.Amaphampu okushisa ezindaweni ezibandayo ngokuvamile asebenzisa iziqandisi ezinamaphoyinti abilayo aphansi kuneziqandisi zephampu zokushisa ezivamile.Lezi ziqandisi zingaqhubeka nokugeleza ohlelweni emazingeni okushisa aphansi asendaweni futhi zimunce ukushisa okwengeziwe emoyeni obandayo.
Idizayini ye-Compressor
Kule minyaka eyishumi edlule, abakhiqizi benze intuthuko kuma-compressor ukuze banciphise amandla adingekayo ukuze basebenze futhi bathuthukise ukuqina.Amaphampu okushisa ezindaweni ezibandayo ngokuvamile asebenzisa ama-compressor ahlukahlukene angalungisa isivinini sawo ngesikhathi sangempela.Ama-compressor esivinini endabuko angaguquki “avuliwe” noma “acishiwe”, angasebenzi ngaso sonke isikhathi.
Ama-compressor aguquguqukayo angasebenza ngephesenti eliphansi lesivinini sawo esiphezulu esimweni sezulu esipholile abese eshintshela esivinini esiphezulu emazingeni okushisa aphezulu.Lawa ma-inverters awasebenzisi zonke izindlela noma azisebenzisi nhlobo, kodwa kunalokho akhipha inani elifanele lamandla ukuze kugcinwe indawo yasendlini isezingeni elifanele.
Okunye ukulungiselelwa konjiniyela
Nakuba wonke amaphampu okushisa asebenzisa inqubo efanayo eyisisekelo ukudlulisa amandla, ukuthuthukiswa kobunjiniyela okuhlukahlukene kungathuthukisa ukusebenza kahle kwale nqubo.Amaphampu okushisa kwesimo sezulu esibandayo angasebenzisa ukugeleza komoya okuncishisiwe, ukwanda komthamo we-compressor, kanye nokucushwa okuthuthukisiwe kwemijikelezo yokucindezela.Uma usayizi wesistimu ulungele ukusetshenziswa, lezi zinhlobo zokuthuthukiswa zinganciphisa kakhulu izindleko zamandla, ngisho nasebusika obubandayo baseNyakatho-mpumalanga, lapho amaphampu okushisa ehlala esebenza khona.
Ukuqhathaniswa phakathi kwamaphampu okushisa namasistimu okushisa endabuko ezindaweni ezibandayo
Ukusebenza kahle kokushisisa kwephampu yokushisa kukalwa nge-Heating Season Performance Factor (HSPF), ehlukanisa inani eliphelele lokukhipha ukushisa phakathi nenkathi yokushisisa (okukalwa ngamayunithi ashisayo ase-British noma ama-BTU) ngesamba esisetshenziswa amandla ngaleso sikhathi (okukalwa nge-kilowatt amahora).Uma iphezulu i-HSPF, ingcono ukusebenza kahle.
Amaphampu okushisa ezindaweni ezibandayo angahlinzeka nge-HSPF ka-10 noma ngaphezulu - ngamanye amazwi, adlulisa amandla amaningi kakhulu kunalawo awasebenzisayo.Phakathi nezinyanga zasehlobo, iphampu yokushisa ishintshela kumodi yesiqandisi futhi isebenze kahle (noma ngokuphumelelayo) njengeyunithi yesiphephetha-moya esisha.
Amaphampu okushisa aphezulu e-HSPF angakwazi ukubhekana nesimo sezulu esibandayo.Amaphampu okushisa ezindaweni ezibandayo asenganikeza ukushisa okuthembekile emazingeni okushisa angaphansi kuka -20 ° F, futhi amamodeli amaningi asebenza kahle ngo-100% emazingeni okushisa angaphansi kwendawo yokuqandisa.Ngenxa yokuthi amaphampu okushisa adla ugesi omncane esimweni sezulu esipholile, izindleko zabo zokusebenza ziphansi kakhulu uma kuqhathaniswa nezinhlelo zendabuko ezifana nezithando zomlilo nama-boilers.Kubanikazi bezakhiwo, lokhu kusho ukonga okukhulu ngokuhamba kwesikhathi.
Lokhu kungenxa yokuthi amasistimu omoya aphoqelelwe njengeziko legesi yemvelo kufanele akhiqize ukushisa, kunokuba akudlulise kusuka endaweni eyodwa kuya kwenye.Isithando somlilo esisha sha esisebenza kahle kakhulu singafinyelela izinga lokusebenzisa uphethiloli elingu-98%, kodwa ngisho nezinhlelo zephampu yokushisa ezingasebenzi kahle zingafinyelela ukusebenza kahle okungama-225% noma ngaphezulu.
