Pakusarudza mishonga yemumba inoda mudzimba imwe neimwe - firiji - zvinhu zvakawanda zvinofanira kutorwa munyaya yacho: muumbi, zviyero, mavhenekeri emakamuri ekuvhenekera uye mafiriji, nzvimbo yavo, rudzi rwechando (kunyura uye kwete yechando ), nhamba yemasuwo, ruvara uye kunze kwekugadzira, nezvimwewo. chinhu chakakosha parameter ndiyo simba yekushandisa yefriji. Izvi ndizvo zvatichakurukura munyaya ino: Tichakuudza kuti chii uye kuti chii chinoshandiswa kushandiswa kwesimba chiri nani.
Simba kirasi: zvinorevei?
Kuwedzera kwekucherechedza kushandiswa kwesimba kwemidziyo mumba, takatanga kubhadhara munguva pfupi yapfuura. Asi kilowatt yese yesimba ndiko kushandiswa kwezvinhu zvisingarevi zvisikwa zvepanyika yedu: ingava gesi, mafuta, marasha. Kubvumirana, mudzimba kune zvakawanda zvigadzirwa zvakabatana nemagetsi emagetsi. Uye firiji inongova imwe yemashandisirwo ayo anoshanda nguva yose, mwedzi, makore, "kumhepo" kilowatts pamamita asina rimwe shanduro. Uye shure kwezvose, kubhadhara kwemagetsi gore roga roga kuri kuwedzera, izvo zvinoratidzwa mumaresidzi emwedzi. Nokudaro, vanogadzirisa midziyo yemumba vakatora basa rekuvandudza refrigerators uye simba ravo rinoshandiswa. Sangano reEurope rinoshandisa simba refrijiji rakagamuchirwa, maererano nekushandiswa kwemasimba emashandisirwo kunotsanangurwa netsamba dzechiLatini kubva kuA kusvika kuG. Shanduro yekushandisa simba iyo inoyerwa nehuwandu hwemagetsi hunoenzanisa, kuongororwa kuongororwa uye nedzimwe shanduko yakaoma kunzwisisa zvichienderana nemagadzirirwo akasiyana-siyana-chaiwo mashandisirwo emagetsi egoreji mu kW, kutengesa kwechigadziro chairo, nhamba yemakamera, ivhu razvo, rudzi rwehuwandu uye kushandiswa kwesimba.
Makirasi emagetsi anoshandiswa kwefriji
Kubva pane zvose zviratidzo, zvidzidzo zvinomwe (A, B, C, D, E, F, G) zvakatanga kuziviswa zvichienderana nehuwandu hwemagetsi. Nezvekuti simba rekushandisa rekushandisa A rinorevei, rinofanira kucherechedza kuti firiji ine chimiro chakadai inofanira kunge ine simba rekugadzirisa simba risingaverenge 55%. Icho chaiva firiji neichi chiratidzo chokuti kusvikira munguva pfupi yapfuura yainzi inonyanya kukosha. Zvisinei, kufambira mberi hakusi kumira, uye nekuda kwekushandiswa kwemazuva emitambo, zvigadzirwa zvakanakisisa zvakasikwa. Saka kubva muna 2003, mazano matsva akapinda musimba, maererano nezvakadzidza zvikamu zveA A + uye A ++ zvakanyanya. Uyezve, firiji A + haifaniri kushandisa magetsi zvinopfuura 42%, uye chigadziriswa neA ++ simba rekushandisa girasi hachifaniri kudarika 30% emitemo ye normative. Nenzira, mugove wehuwandu hwekugadzirwa kwefrijiji inenge 70% uye iri kuramba ichiwedzera.
Kana tichitaura pamusoro pesimba rekushandisa B yefriji, ipapo zvigadziro zvekuchengetedza michina ine mazita akadaro zvinoonekwawo sehupfumi, kunyange, kusvika pamwero muduku, kupfuura kirasi A. Nhamba yehuwandu hwemagetsi ayo kubva pa55 kusvika ku75%. Hirijiji rine simba rekushandisa kesitari C rinorevawo nezvehuwandu hwehuwandu hwemagetsi, asi nechokwidziri chepamusoro (75 kusvika 95%).
Kana uri pafiriji unowana ruvara rwechirairo nokuda kwesimba rekushandisa dhidha D, gara uchiyeuka kuti chigadzirwa chakadaro chine uwandu hwepakati pehupfumi (kubva pa95 kusvika ku10%).
Asi firiji yakanyorwa E, F, G inhengo yekirasi ine yepamusoro uye yakasimba zvikuru simba (kubvira 110% kusvika 150%).
Nenzira, nekuda kwesimba ravo risina simba, mafiriji ane simba rekushandisa girasi D, E, F uye G haana kubudiswa mumakumi mashoma apfuura.
Sezvaunogona kuona, paunotenga firiji, unofanirwa kubhadhara kushandiswa kwesimba rayo. Kucherechedza kwaro kunogona kuonekwa pamuviri wechigadziro nenzira yeshoko.
