Ubuchwepheshe Bokulawula Ukushisa Kwefriji Okuguqukayo
Emashumini eminyaka amuva nje, umhlaba we-air conditioner (i-HVAC—Ukushisa, Umoya Ongenisayo, kanye ne-Air Conditioning) uthuthuke ngokushesha ukuze uhlangabezane nezidingo ezimbili ezibalulekile: ukwandisa induduzo yokushisa kanye nokusebenza kahle kwamandla okunzima ngokwengeziwe. Phakathi kwalezi zidingo, kuye kwavela izinto ezintsha ezahlukahlukene ezigxile ezindleleni ezihlakaniphile zokuphatha amandla okupholisa nokushisa. Ubuchwepheshe obunye obusetshenziswa kakhulu ezinhlelweni zokupholisa zesimanje—kungaba ezokuhlala, ehhovisi, noma ezentengiselwano—yi-Variable Refrigerant Temperature Control (VRTC).
Lobu buchwepheshe bulawula izinga lokushisa le-refrigerant ukuthi lishintshe ngokuya ngesidingo somthwalo kanye nezimo zemvelo, kunokugcina izinga lokushisa lokusebenza lizinzile njengezinhlelo ezivamile. Umphumela uba ukusebenza okuguquguqukayo, ukusetshenziswa kwamandla okuphansi, kanye nenduduzo yomsebenzisi ethuthukisiwe.
Kuyini Ukulawula Ukushisa Kwefriji Okuguquguqukayo?
Kalula nje, i-Variable Refrigerant Temperature Control iyindlela yokulawula uhlelo lwesiqandisi/lwe-AC oluvumela iyunithi ukuthi ishintshe ngokuguquguqukayo amazinga okushisa ahwamukayo kanye/noma anciphayo esiqandisini. Emjikelezweni wesiqandisi, la maphuzu amabili okushisa anquma kakhulu ukusebenza kahle kwe-compressor kanye nekhono lesistimu lokumunca nokukhulula ukushisa.
Ezinhlelweni zendabuko, amazinga okushisa okuhwamuka kanye nokufiphala avame ukuba sebangeni eliqinile ngoba ukulawulwa komthamo kuvame ukwenziwa ngezinqubo zokuvala noma zesinyathelo ngesinyathelo. Ngenxa yalokho, lapho umthwalo wokupholisa uphansi (isb., ebusuku, lapho igumbi selipholile kakade, noma lapho amanye amakamelo engasetshenziswa), uhlelo alukwazi ukuzivumelanisa kahle. I-compressor ingasebenza kanzima kunokudingekile noma ingavula futhi icime njalo, iphazamise ukuzinza kokushisa futhi ikhulise ukusetshenziswa kukagesi.
Nge-VRTC, uhlelo lungalungisa “izinga lokushisa eliqondiwe” le-refrigerant ukuze i-compressor nezinye izingxenye zisebenze ngezimo ezisebenza kahle kakhulu zomthwalo wamanje.
Indlela Okusebenza Ngayo: Kungani Ukushintsha Izinga Lokushisa Lefriji Kungonga Amandla?
Ukusebenza kahle kwamandla kwesistimu yokupholisa kuthonywa kakhulu umehluko wokucindezela kanye nokushisa phakathi kwezinhlangothi ze-evaporator kanye ne-condenser. Ngokuvamile:
– Uma izinga lokushisa lokuhwamuka likhuphuka (i-evaporator isebenza ngokushisa okuphezulu kancane), ingcindezi yokumunca ye-compressor iyanda, yehlisa isilinganiso sokucindezela. Lokhu kusho ukuthi i-compressor akudingeki "ipompe" i-refrigerant njengoba iqine, okunciphisa ukusetshenziswa kwamandla.
– Uma izinga lokushisa lokuncibilikisa lincishisiwe (i-condenser isebenza ngezinga lokushisa eliphansi, ikakhulukazi uma izinga lokushisa langaphandle liphansi), ingcindezi yokukhipha i-compressor incishisiwe. Umphumela uyafana: isilinganiso sokucindezela siyathuthuka futhi uhlelo luba ngcono kakhulu.
Ngamanye amazwi, i-VRTC ilwela ukugcina uhlelo lusebenza "endaweni enhle" ehambisana nezimo zangempela. Uma umthwalo uphansi noma indawo ivuma, uhlelo luzokhetha izimo zefriji ezisebenza kahle kakhulu. Uma umthwalo uphezulu, uhlelo lunganciphisa izinga lokushisa lokuhwamuka ukuze lufinyelele amandla amakhulu okupholisa.
Izingxenye Eziyinhloko Ezisekela i-VRTC
Ubuchwepheshe bokulawula izinga lokushisa le-Refrigerant obuguquguqukayo buvame ukuhambisana nezingxenye nezici zesimanje, njenge:
1. I-inverter compressor (i-compressor yesivinini esiguquguqukayo)
I-compressor ye-inverter ingalawula ijubane lokujikeleza kwemoto, okuvumela izinguquko ezibushelelezi ekugelezeni kwesisindo se-refrigerant. Ngaphandle kwe-inverter, i-VRTC ingaba nzima ukuyisebenzisa ngokunembile ngenxa yokulawula umthamo okulinganiselwe.
