Uma kuziwa ekufakeni izinto, kubalulekile ukuthi abakhi nabanikazi bezindlu ngokufanayo baqonde amamethrikhi ahlukahlukene asetshenziselwa ukuhlola ukusebenza kwawo. Kulawa mamethrikhi, inani le-K, inani le-U, kanye nenani elingu-R yizona ezisetshenziswa kakhulu. Lawa manani akhombisa ukusebenza okushisayo kwemikhiqizo yokufakelwa, okuhlanganisa ukufakwa kwe-FEF (foam extruded polystyrene). Lesi sihloko sizohlola ubudlelwano phakathi kwalawa magugu nokuthi ahlobana kanjani nemikhiqizo yokufakwa kwe-FEF.
Inani le-K: i-coefficient ye-thermal conductivity
I-K-value, noma i-thermal conductivity, isilinganiso sekhono lempahla lokuqhuba ukushisa. Iyunithi yayo i-Watts imitha-Kelvin (W/m·K). Uma i-K-valu iphansi, i-insulation ingcono, kodwa lokhu kusho ukuthi impahla iqhuba ukushisa kancane ngokuyimpumelelo. Okwezinto ezisetshenziswayo zokuhlanganisa i-FEF, inani le-K libalulekile ngoba lithinta ngokuqondile ikhono lempahla lokumelana nokugeleza kokushisa. Imvamisa, imikhiqizo yokufakwa kwe-FEF inamavelu e-K aphansi, okuyenza iphumelele kakhulu ezinhlelweni ezihlukene, kusukela ezakhiweni zokuhlala ukuya kwezohwebo.
Inani le-U: I-coefficient yokudlulisa ukushisa iyonke
Inani le-U libonisa i-coefficient yokudlulisa ukushisa iyonke yesici sesakhiwo, njengodonga, uphahla noma phansi. Ivezwa ngama-Watts ngemitha-skwele ngayinye-Kelvin (W/m²·K) futhi ayinaki nje into efakwayo, kodwa futhi nemiphumela yezikhala zomoya, umswakama nezinye izici. Lapho i-U-valu iphansi, i-insulation ingcono, njengoba kusho ukushisa okuncane okulahlekile noma okuzuzwa nge-elementi yokwakha. Lapho uhlola imikhiqizo yokuhlanganisa ye-FEF, inani le-U libalulekile ukuze uqonde ukuthi lizosebenza kanjani emhlabeni wangempela, ikakhulukazi uma lihlanganiswa nezinye izinto zokwakha.
Inani lika-R: ukumelana nokugeleza kokushisa
I-R-value ikala ukumelana nokushisa kwento, ekhombisa ukuthi imelana kahle kangakanani nokugeleza kokushisa. Amayunithi ayo ayimitha-skwele-Kelvin ngewathi ngayinye (m²·K/W). Uma liphakeme inani le-R, kuba ngcono ukugqumisa, okusho ukuthi izinto ezibonakalayo zivimba ngempumelelo kakhulu ukudluliswa kokushisa. Imikhiqizo yokufaka i-FEF ngokuvamile inamanani aphezulu e-R, okuyenza ilungele ukwakhiwa okuwonga amandla. I-R-value ibaluleke kakhulu kubanikazi bezindlu abafuna ukunciphisa izindleko zamandla futhi bakhulise ukunethezeka kwezindawo zabo zokuhlala.
Ukuhlobana phakathi kwevelu engu-K, inani elingu-U kanye nenani elingu-R ekufakweni kwe-FEF
Ukuqonda ubudlelwano phakathi kwenani le-K, inani le-U kanye nenani le-R kubalulekile ekuhloleni ukusebenza kwemikhiqizo yokuhlanganisa ye-FEF. Inani le-K ligxile kokokusebenza ngokwayo, inani le-R likala ukumelana kwayo, futhi inani lika-U linikeza isithombe esibanzi sokusebenza kukonke kwesici sokwakha.
Ukuhlobanisa lawa manani ngokwezibalo, le fomula elandelayo ingasetshenziswa:
- **R-value = 1 / K-value**: Lesi sibalo sisho ukuthi njengoba inani lika-K lincipha (libonisa ukuguquguquka okungcono kwe-thermal), inani le-R liyakhuphuka, okusho ukusebenza okuthuthukisiwe kwe-insulation.
- **Inani elingu-U = 1 / (inani lika-R + ezinye izihluthulelo)**: Le fomula ibonisa ukuthi inani lika-U alithintwa nje kuphela inani elingu-R lesendlalelo sokuvala, kodwa futhi nezinye izici ezifana nezikhala zomoya namabhuloho ashisayo.
Emikhiqizweni yokufaka i-FEF, amanani aphansi e-K anikela kumanani aphezulu we-R, nawo asize ukufeza amanani aphansi we-U lapho ehlanganiswa nemihlangano yokwakha. Lo mphumela we-synergistic wenza ukwahlukanisa kwe-FEF kube ukukhetha okudumile kubadwebi bezakhiwo nabakhi abafuna imiklamo eyonga amandla.
Kafushane, inani le-K, inani le-U kanye nenani lika-R yizinkomba ezihlobene ezinikeza imininingwane ebalulekile ekusebenzeni okushisayo kwemikhiqizo yokuhlanganisa ye-FEF. Ngokuqonda lobu budlelwano, abakhi nabanikazi bezindlu bangakwazi ukwenza izinqumo ezinolwazi mayelana nezinto zokufakelwa, ekugcineni bakhe izindawo zokuhlala ezonga amandla nezinethezekile. Njengoba ukusebenza kahle kwamandla kuqhubeka nokuba yinto eza kuqala embonini yezokwakha, ukubaluleka kwalawa manani kuzokwanda kuphela, ngakho-ke kufanele kubhekwe lapho kukhethwa izixazululo zokufaka izinto.
