The newly built cold storage system should be vacuumized before filling refrigerant. As for the harm of not vacuumizing, we have said many times that the refrigeration encyclopedia public number is not repeated here. First connect the tee gauge to the suction and exhaust Angle valves of the compressor, open the Angle valve, and open the vacuum pump to vacuum. Generally, stop vacuumizing when the temperature reaches -0.1mpa (760mmHg). The vacuumizing time depends on the size of the cold storage and vacuum pump, and the pressure value displayed on the pressure gauge.
Kerak e'tibor bering! It qat'iy taqiqlangan to foydalanish uchun kompressor to vakuum, chunki bilan chuqurlashtirish the vacuum degree in the sovutish kompressor shell, the izolyatsiya o'rta orasidagi yo'qolgan ta'sirlangan bin postlar yoki shamollatish bilan kichkina shikastlanish bilan izolyatsiya qatlami. Bir marta bir marta elektr energiyasi energiya 2c bo'lsa motor bo'lishi mumkin qisqa tutashuv va yonib kirish an an an. Agar qobiq chiqishlari, u bo'lishi mumkin elektr shok.
Keyin vakuumlash, tayyorlang to add sovutuvchi. Biz kerak to tushuning ki to'g'ri miqdor of sovutuvchi to'ldirish sovuq saqlash is the key factor to aniqlash operatsiya efficiency of sovutish tizimi!
Masalan, yetarli bo'lmagan sovutuvchi to'ldirish miqdori in sovuq saqlash bo'ladi emish bosimi va egzoz bosimi 2c ayniqsa uchun qaytish havo sovutish kompressor may shuningdek sabab motor qizib ketish; Agar sovutgich miqdori juda yuqori, bo'ladi kompressor shikastlanishi mumkin shikastlangan tufayli jiddiy sovuq of of the bug'lashtiruvchi, yuqori kondensat bosimi, yoki suyuqlik qaytish bug'lovchi ning bug'lovchi dir. Agar bir xil sovutish uskunalari, chunki the the ichki sovuq saqlash hajmi, bug'lanish harorati, kondensat bosim farq 2c va turli optimal sovutuvchi to'ldirish miqdori.
In the ta'mirlash of sovuq saqlash sovutish tizimi, in eng holatlarda, gazli yoki suyuq sovutuvchi zaryad mumkin dan zaryad olish mumkin the past bosim tomoni. qachon sovutuvchi ning miqdori katta, suyuqlik sovutuvchi mumkin shuningdek be zaryadlangan dan zaryadlangan dan yuqori bosim tomoni. Diqqat kerak! Agar agar siz zaryad suyuq sovutgich dan agar agar siz zaryad suyuq sovutgich dan past bosim yon, be ga ishonch komil qo qo shish asta to qochish suyuqlik zarbasi! Agar agar siz qo'rqsangiz suyuqlik shok, gaz dan qo'rqasiz ham to'ldirilishi mumkin.
Usuli qo'shish sovutuvchi dan past bosim tomoni:
Dan past voltaj yon to'ldirish gaz sovutuvchi operatsiya, past bosim tee birinchi globus spin counterclockwise to the endpoint, then add the fluorine pipe joint in the low pressure of the {{0} }way valf bypass seat, then ochiq shisha of R22 fluorine silindr valflari, to bypass of of the silk of cut-off valve nipple let a oz, will add fluoride tube R22 gaz out of of havo, On eshitish a % 22hissing, hissing" havo oqimi tovush at at the joint, darhol lock it va sovutuvchi zaryadlash boshlanadi.
the in'ektsiya miqdori yetganda the belgilangan sifat, yopish the fluorine bottle stop valve, rotate the low-pressure three-way stop valve to the end end nuqta qarshi ampokokga qarshi, yaqin botiq val of R22 fluorine bottle, remove the fluorine pipe, and the fluorine adding work is finished.
