Khoom Description

R407C R407 C refrigerant gas

Raws li cov tub yees nruab nrab thiab kub kub tau dav siv niaj hnub no, R-407C yog siv los hloov R22 thiab R502. Nws muaj cov yam ntxwv ntawm kev huv, tsis muaj tshuaj lom, tsis muaj nplaim taws, thiab ua kom txias txias. Nws yog tsuas yog siv hauv cov tshuab cua txias hauv tsev, cov tshuab cua txias me me thiab nruab nrab (me me thiab nruab nrab chav tsev hom Cua txias, lub tshuab cua hauv tsev hauv nruab nrab, ntau qhov sib cais), lub tshuab cua txias (lub tsheb cua txias, thiab lwm yam) , dehumidifiers, tub yees dryers, marine refrigeration khoom, industrial tub yees thiab lwm yam khoom siv tub yees. Raws li kev hloov mus sij hawm ntev rau R22, R407C feem ntau yog siv hauv cov tshuab cua txias thiab cov tshuab tsis muaj centrifugal.

R407c refrigerant Daim ntawv thov

R-407C yog qhov nruab nrab thiab siab kub tub yees siv dav siv niaj hnub no. Nws yog tsuas yog siv hauv cov tshuab cua txias hauv tsev, cov cua txias me me thiab nruab nrab (me me thiab nruab nrab chav tsev cua txias, chav tsev hauv nruab nrab cua txias, ntau qhov sib cais), lub tshuab cua txias (lub tsheb cua txias, thiab lwm yam), dehumidifiers,

Cov tub yees tshuab ziab khaub ncaws, cov khoom siv tub yees tubrog nkoj, tub yees thiab lwm yam khoom siv tub yees.performance rau R22 thiab tuaj yeem siv los kho cov tshuab cua txias uas tsim los siv R22. R407C kuj tseem tuaj yeem hloov R502 hauv nruab nrab kub nruab nrab uas twb muaj lawm.

ceeb toom

R407C thiab R22 muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg, kev ua haujlwm theoretical voj voog, thiab roj compressor. Yog li ntawd, tom qab kev muag khoom ntawm cov khoom siv tub yees pib nruab nrog R22 tub yees, yog tias koj xav tau ntxiv lossis hloov cov tub yees, koj tseem tuaj yeem ntxiv R22 xwb. Feem ntau R407C tsis tuaj yeem siv los hloov R22 ncaj qha (kev hloov pauv hloov tsis tuaj yeem ua tau; Txawm li cas los xij, rau cov khoom siv tub yees pib nrog R22, R417A tuaj yeem siv los hloov R22 ncaj qha thaum kho lossis hloov).

R407C tuaj yeem siv rau hauv thawj R22 system yam tsis muaj kev rov tsim kho lub system. Nws tsuas yog yuav tsum tau hloov ob peb ntu ntawm cov txheej txheem qub thiab hloov cov roj hauv lub tub yees hauv cov txheej txheem qub nrog cov roj lubricating (POE roj) uas yog miscible nrog R407C, thiab tom qab ntawd nws tuaj yeem sau ncaj qha. R407C, paub txog ib puag ncig tus phooj ywg hloov ntawm cov khoom qub.
