Iyunithi engundoqo: Watt (W)
Iyunithi esemgangathweni yamazwe ngamazwe yokutshintsha ubushushu (ekwaziwa ngokuba kukuhamba kobushushu) yi-watt (W). Le yeyona yunithi ixhaphakileyo nekhethwayo kwiimo zorhwebo zamazwe ngamazwe, ukuqinisekisa ukuqondana okungaguqukiyo phakathi kwamaqabane oshishino lwehlabathi.
1. Inkcazelo yeYunithi:Iwathi enye ingqamana nejowule enye ngesekhondi (1W=1J/s), yona isixa sobushushu esidluliswa ngesixhobo sokutshintsha ubushushu ngeyunithi nganye yexesha. Ngokomzekelo, umtshintshi wokushisa kunye nomlinganiselo wokushisa we-5000W uthetha ukuba unokudlulisa i-5000 joules yokushisa ngomzuzwana.
2. IiYunithi eziSetyenziswa ngokuqhelekileyo:Ngenxa yokwahluka okubalulekileyo kumazinga okutshintshana kobushushu kwizicwangciso zoshishino, iiyunithi eziphindaphindwayo zisetyenziswa rhoqo kwizicelo ezisebenzayo. Oku kufuneka kuboniswe ngokucacileyo kumaxwebhu orhwebo lwamazwe ngamazwe:
- I-Kilowatt (kW): 1 kW=1000 W, ilungele abatshintshisi bobushushu abancinci naphakathi{3}}abanjengendawo yokuhlala yokutshintsha ubushushu be-air conditioner, ii-coolers ezincinci zamashishini), kwaye iyiyunithi esetyenziswa rhoqo kwiikowuteshini zorhwebo lwamazwe ngamazwe kunye neetafile zeeparameter.
- IMegawathi (MW): 1 MW=10⁶ W, ilungele izixhobo ezinkulu zemizi-mveliso (ezifana neziguquli zeplanti yombane kunye nezitshintshisi zobushushu zereactor yeekhemikhali), ezidla ngokusetyenziswa{3}}kwixabiso leprojekthi enkulu kunye nezivumelwano zobugcisa.
. IiYunithi ezisetyenziswa ngokuqhelekileyo kweminye iMimandla/Amashishini
Ezinye iimarike zaphesheya (ezifana noMntla Melika kunye namashishini athile emveli aseYurophu) zisenokusebenzisa{0}}iiyunithi zamazwe ngamazwe; ke ngoko, kuyafuneka ukuqonda ubudlelwane benguquko obuhambelanayo ukunqanda iimpazamo zonxibelelwano:
1. Iiyunithi ze-Imperial: iiyunithi ze-thermal zaseBritani ngeyure (BTU/h)
- Inkcazo: I-1 BTU / h imele ukuhanjiswa kweyunithi ye-thermal ye-1 yaseBritani yobushushu ngeyure kwaye iyunithi esetyenziswa ngokuqhelekileyo kwi-HVAC yaseNyakatho yaseMelika kunye namashishini efriji.
- Ubudlelwane bokuguqulwa: 1 BTU / h ≈ 0.293 W, 1 kW ≈ 3412 BTU / h (Le yifomyula engundoqo yokuguqulwa kweeparamitha zorhwebo zamazwe ngamazwe kwaye kufuneka zikhunjulwe ngokuchanekileyo).
- Imeko yesicelo: Xa unxibelelana nabathengi base-US nabaseKhanada malunga ne-air conditioners encinci kunye ne-heater pump exchanger heat, kuyimfuneko ukubonelela zombini iiyunithi ze-W (okanye i-kW) kunye ne-BTU / h ngaxeshanye ukuphucula ukuhambelana koxwebhu.
2. Iikilocalories ngeyure (kcal/h)
- Ingcaciso: I-1 kcal/h imele ukuhanjiswa kwe-kilocalorie e-1 yobushushu ngeyure. Le yunithi yayisetyenziswa kakhulu eYurophu, eJapan, eMzantsi Korea, nakwinqanaba lokuqala lamashishini asekhaya, kwaye isasetyenziswa kwezinye iifektri zemveli namhlanje.
- Ubudlelwane bokuguqulwa: 1 kcal / h ≈ 1.163 W, 1 kW ≈ 859.8 kcal / h.
- Imeko yesicelo: Xa usebenzisana neenkampani zekhemikhali zesintu eJapan, eMzantsi Korea, naseMpuma Yurophu, kubalulekile ukuqwalasela ukuba ngaba baqhelile na ukusebenzisa leyunithi yomlinganiselo. Kucetyiswa ukuba kufakwe iinkcazo zokuguqulwa kumaxwebhu obugcisa.
Iingqwalasela ezibalulekileyo zokuSetyenziswa kweYunithi
Ukubeka phambili ukusetyenziswa kweeyunithi ezisemgangathweni zamazwe ngamazwe
Kwiikontraka zorhwebo zangaphandle, amaphepha eparameter, kunye neencwadana zemveliso, beka phambili ukusetyenziswa kwe-watts (W) kunye nokuphindaphinda kwayo (kW, MW). Iiyunithi{1} ezingezizo zamazwe ngamazwe zinokusetyenziswa njengolwazi olongezelelweyo, kodwa kuphephe ukuzisebenzisa njengeyona yunithi iphambili ukuthintela iimpazamo kwiikowuteshini kunye nokukhethwa kwemveliso ngenxa yokungangqinelani kweyunithi.
Chaza ngokucacileyo isiseko soguqulo
Ukuba umthengi ucela ukusetyenziswa kweeyunithi ezingeyiyo{0}}yamazwe ngamazwe, ifomyula yokuguqulwa kufuneka iboniswe kuxwebhu ukuze kuqinisekiswe ukuba omabini amaqela anengqiqo ehambelanayo yezibonakaliso zokusebenza (umzekelo, "Ixabiso lokutshintsha kobushushu besixhobo yi-5 kW, ephantse ilingane ne-17060 BTU / h").
Ukwahlula phakathi "kwezinga lotshintshiselwano lobushushu" kunye "ne-coefficient yokudluliselwa kobushushu"
Kuphephe ukubhideka kweyunithi-iyunithi yokutshintsha ubushushu yi-W (amandla/ixesha), ngelixa iyunithi yomlinganiso wogqithiso lobushushu (ixabiso le-K) ingu-W/(m²·°C). La magama mabini achaza "ukutshintshwa kobushushu buphela" kunye "nomthamo wokutshintshwa kobushushu kwindawo nganye yeyunithi," ngokulandelelanayo, kwaye kufuneka icace ngokucacileyo kunxibelelwano lwezorhwebo lwamazwe ngamazwe.
