Kungekudala, kwakudingeka ukuba uphuphe ukuphuza iziphuzo ezipholileyo kwimvelo, kodwa ngokufika kwezifriji eziphathekayo, ukuthanda abantu abathandwayo kwindalo, ukuhamba, ukuloba nokuzingela banikezwa ithuba, kwaye baqala ukungabi nangoyika ukuthabatha ukutya okunokutsha. Malunga neentlobo zezi zixhobo kufuneka zifunde ngokusondeleyo.
Iindidi zezixhobo zokupholisa eziphathekayo:
- izikhwama ezifudumele;
- izitya;
- iifriji ezizenzekelayo;
- iifriji zokufakela;
- imizekelo yoxinzelelo.
Izikhwama kunye nezitya
Ngokomgaqo wesenzo, bafana kakhulu. Iingxowa ze-thermal zenziwa ngongqinileyo kwaye zenziwe ngeendonga ezimbini, phakathi kweso sakhiwo sokubeka ukutshisa ukushisa, esenziwe, njengokulawula, i-polyethylene foam. Enyanisweni-i-friji-thermos ephathekayo, eyenzelwe ukugcina ukushisa kokutya, ngoko ingasetyenziselwa ukugcina ubanda, kodwa nokushisa. Ngokomyinge, igcina ubushushu beeyure ezili-10. Isikhundla siyahluka, ukususela kwi-3 ilitha ukuya kuma-70 ilitha. Isikhwama esilungeleyo esilungeleyo sineenkomfa kakhulu kwaye sinokuphangwa kwaye sisuswe ngokungadingekile.
Izikhuni zelanga zizinzileyo, ezinokuthi zenziwe ngeplastiki, insimbi engenasici, njl. Iindonga zayo zinyene, kwaye ngoko izakhiwo zokukhupha izitshalo ziphezulu. Bagcina ubushushu bokuqala besiselo kunye nezitya ukuya kwiiyure eziyi-15. Iinqwelo zixhotywe ngesiphathi esifanelekileyo nesigxina, kwaye zingasetyenzisi nje kuphela njengetafile, kodwa nokuba sihlalo.
Iifriji ezizizenzekelayo kunye nezinye izinto
Iifriji ezincinane eziphathekayo zeemoto zixhunyiwe kwigridi yamagunya ayi-12-volt. Zidla malunga nomlinganiselo ofanayo wamandla njengebhuru elidlula. Kuyilo lwedivayisi kukho iiplati ze-thermoelectric zecala. Xa ugunyaziso lwamandla kagesi ludlula kubo, uhlangothi lwangaphakathi lwamacwecwe luyacima, kwaye igumbi leemveliso licolile. Xa kuthengiswa kunokwenzeka ukuba ufumane imodeli kunye nomsebenzi wokufudumeza, owenza utshintsho kwi-polarity of voltage. I-friji ye-friji ye-auto-friji ayikwazi ukuhwankqisa ukutya, kodwa isebenza ixesha elide kunezinye ezimbini. Ndimele ndithi ixesha lokusebenza lazo zixhobo ezintathu ezichazwe ngentla zinganwetshwa ngokusebenzisa i-accumulators ezibandayo - izitya zeplastiki ezine-saline, isisombululo esidlulileyo.
Ukuqhwala ngokukhululekile kunokwenza i-gas-electric okanye i-refrigerators ezincinane eziphathekayo. Indima yefriji kwiimodeli zidlalwa yisisombululo se-ammonia. Ukusasazwa kwayo ngekimu ekhethekileyo kunika umbane okanye ugesi, kunye nokukwazi kwamanzi ukufumana i-ammonia. Ngoko, ibhotile kunye ne-butane okanye i-propane ye-5 liters amandla iyakwazi ukubonelela ngefriji ukuya kwiintsuku eziyi-8, kodwa iyakwazi ukusebenza kumbane. Iiyunithi zeCompressor zisenokuqhathaniswa neefriji eziqhelekileyo, kuba i-compressor inoxanduva lokusasazwa kwefriji. Zizococa kwaye zipholisa iimveliso ngokukhawuleza, kodwa i-berry ephosayo ephathekayo iyayikhathalela ukutshatyalazwa kunye neentshukumo.
Imiba yokusebenza
Ukuthetha ngamabhethri okugcina abandayo, kubalulekile ukuba uqaphele ukuba bafika kwimilinganiselo eyahlukeneyo, kuxhomekeke kumandla webhegi okanye isitya. Ingxube ngaphakathi kwisisombululo setyuwa, ehambelana nebhetri "esebenzayo", inokuthi ihluke. Ngaloo ndlela, ibhetri ye-300-ml ingakwazi ukugcina ubushushu beelitha ezili-10 zokutya nokusela, kunye nebhegi enkulu, kufuneka uthenge amabhetri amakhulu. Abavelisi batusa ukuba basebenzise yonke ivolumu yokusebenza yesiqandisisi.
