Uyini umehluko phakathi kwesiqandisi sika-R22 no-R410A?

1. Isifriji esingu-R410 sidinga ukusebenzisa uwoyela wokwenziwa esiqandisini (POE), ngoba uwoyela we-POE une-hygroscopicity ephezulu futhi uthambekele ku-hydrolysis. Uma kuqhathaniswa no-R22, uhlelo lwe-R410A lunezidingo eziqinile zokuqukethwe komswakama.

2. Ngokuya ngevolumu yokugcoba, ngemuva kokuncishiswa kwesakhiwo sokushintsha ukushisa, umthamo wamandla wohlelo lwe-R410A wehliswe cishe ngo-20% kuya ku-30% uma kuqhathaniswa nohlelo lwe-R22. Izici zokudlulisa ukushisa ngokuphelele kohlelo lwe-R410A zikhulu kunalezo ze-R22, ukusebenza kahle kokudlulisa ukushisa kuphezulu, futhi umshini wokushisa ungashintshwa ube mncane.

3. I-R410A iyisiqandisi esihlanganiswe ne-HFC-32 (R32) ne-HFC-125. I-R410A inezidingo eziphakeme zamashubhu wethusi, kanti i-R22 ingasebenzisa amashubhu wethusi ajwayelekile; ingcindezi yokusebenza ka-R410A ingu-50 ~ 70% ephakeme kunaleyo ka-R22, cishe izikhathi eziyi-1.6.

4. I-R410A inobuthi obuphansi, ayinakho ukusakazeka komlilo, futhi ayibhubhisi ungqimba lwe-ozone. I-R22 iyabulala futhi iyalimaza ungqimba lwe-ozone; Uhlelo lwe-R410A lunamandla okupholisa kangcono, uma i-R22 ingu-100% wokupholisa umthamo, i-R410A ingu-147% wokupholisa umthamo;

5. Yize i-R410A ingaluqedi ungqimba lwe-ozone, igesi yokushisa engakhiqizi ekhiqizwayo, umphumela wayo wegesi obamba ukushisa ungaphezu kwengxenye idlula u-R22. Ngakho-ke, i-R410A ayisona isixazululo sokugcina esiqandisini semvelo somkhakha wokupholisa umoya waseChina. Haha, bonke labo bangani abathi i-R410A iyisiqandisi esingakulungeli imvelo, ungaphumula.

6. I-R410A inesibalo esiphezulu somhwamuko kuno-R22, ngakho-ke izinga lokugeleza komhwamuko lika-R410A cishe liba ngu-30% kancane kunalelo lika-R22; I-R410A incibilika kakhulu kuno-R22. Lapho izinsalela zintanta ku-R410A, ingazungeza kahle ohlelweni.

Ezinye izindaba ezidinga ukunakwa

1. Amapayipi ethusi angu-R410A kufanele asebenzise amapayipi akhethekile ethunyelwa ukumelana nokuqina kokuqina, futhi izingxenye ezisele nazo kufanele zisebenzise amapayipi ethusi enhloso ekhethekile. Kungasetshenziswa amashubhu wethusi angama-R410a esikhundleni samashubhu ejwayelekile ethusi angama-R22, kodwa akunakwenzeka neze ukufaka amashubhu ethusi angu-R410a ngamabhubhu ejwayelekile e-R22.

2. Lapho kufakwa i-refrigerant split engu-R410A entsha, akumele ididaniswe nepayipi lokuxhuma nefriji esetshenziswa kuma-air conditioner angama-R22.

3. I-R410A air conditioner idinga umthamo ophezulu ofakiwe. Ungaconsi umjuluko kumbhobho wokuxhuma, futhi ungahlanganisi okunye ukungcola okungancibiliki ohlelweni. Kule Refrigeration Encyclopedia, kunconywa ukuthi uhlelo lukhishwe ukuze lungabangeli ukungcoliswa okuxubile kweziqandisi.

4. Ngesikhathi sokulungiswa, uma uhlelo lwefriji luvulwa luvulwe, isihlungi sesihlungi kufanele sishintshwe, futhi uhlelo lwefriji akumele lubekwe emoyeni isikhathi esingaphezu kwemizuzu emihlanu.

5. Isiqandisi esingu-R410 kufanele sigcinwe endaweni engaphansi kuka-30 ° C. Uma igcinwe endaweni ephakeme kuno-30 ° C, kufanele igcinwe endaweni engaphansi kuka-30 ° C ngaphezu kwamahora angama-24 ngaphambi kokuthi isetshenziswe.

6. I-valve yezindlela ezine esetshenziswe ohlelweni lwe-R410A inezidingo ezicacile zenhlanzeko, kanti i-valve enezindlela ezine esetshenziswe ku-R22 system ayinazidingo zenhlanzeko.

7. Ingcindezi enkulu yokusebenza eyenzelwe ukuvalwa kwe-valve evaliwe yehlukile, ukusetshenziswa kwefriji R22 kungu-3.0MPa, kanti ukusetshenziswa kwefriji R410A ngu-4.3MPa. I-R22 iyisixhumi se-3.0 MPa zethusi, kuthi i-R410A isixhumi sensimbi engagqwali esingu-4.3.

8. Inani lengcindezi lokushintshwa kwengcindezi lihlukile, uhlelo lwe-R22 luvame ukukhetha i-3.0 / 2.4MPa, uhlelo lwe-R410A luvame ukukhetha i-4.2 / 3.6MPa.

9. Ngaphansi kwamandla kagesi alinganisiwe, amandla okufuduswa ngakunye (1cc) we-R22 system compressor acishe abe yi-175W, futhi amandla okufuduswa ngakunye (1cc) we-R410A ye-system compressor ecishe ibe ngu-245W, okuyi-65% kuya ku-70% wohlelo lwe-R22. mayelana.

10. Iyunithi engaphandle yohlelo lwefriji imakwe ukuthi hlobo luni lwefriji olusetshenziswa imishini, nokuthi isiphi isiqandisi esisetshenziselwa isiqandisi esimakiwe. U-R22 awunakushintshwa u-R410a uqondiswe ngqo.
