Kuve nekuvandudzwa nesimba rakasvibira uye idzva, OSB yakanga yapa yazvino kupisa pombi R152a.
Unogona kubvunza, chii chinonzi R152a?
Heino ruzivo runogona kubatsira kune imwe pfungwa iri nani.
R152a inowanzo shandiswa sepropellant muaerosols, seanopupa furo, kana sechikamu chemisanganiswa yefiriji, zvisinei, kurongeka kwayo sefiriji inopfuta zvishoma yakaganhurira kushandiswa kwayo mumotokari uye mufiriji yekutengeserana. Nekudaro, ichangoburwa mutero weSpanish we fluoridated greenhouse refrigerants (ine GWP inopfuura 150), pamwe nemiganhu yakaiswa neF-Gas mutemo mukutarisana nekudziya kwepasi, zvakakonzera kufarira patsva mumafiriji anopfuta, uye kunyangwe zvakanyanya. chepfu mafiriji akadai ammonia.
Polyurethane kana R152a yakachena fluoridate hydrocarbon ine maumbirwo akafanana chaizvo neR134a. Iine mhute yekutsikirira curve yakaenzana neR134a, ine kutsauka kwe2K chete, uye ine maitiro emakemikari akaenzana, uye naizvozvo inopindirana nezvose, zvikamu zvefiriji, thermostatic valves, compressors nemafuta ekuzora.
R152a zvakare ine yepamusoro thermodynamic maitiro kune R134a uye Fossa. Iyo yekupisa yekupisa coefficient yefiriji mu evaporator inowedzerwa neinenge 20% nekuda kwehunhu huri nani hwemuviri hweR152a kana ichienzaniswa neR134a. Nekuda kweiyo yakaderera gasi viscosity, kudonha kwekumanikidza mumitsara yekusveta kuchaderedzwa ne30%. Iyo yakaderera molecular huremu hweR152a inoupa yakanyanya kudzika kupisa kwekunyungudika, yakakwirira volumetric kugona kwecompressor, uye zvirinani COP kuita kwefiriji kutenderera, ine tembiricha yekubuda yepamusoro ingangoita gumi kana ichienzaniswa neR134a.
Sei tichida kupisa pombi R152a?
Sezvo iri girinhi uye yakaderera GWP, zvakare ine yakakwira mvura inopisa yekubuda enzanisa neR32.
Uye yakanakira kutsiva iyo R134a yakakwira temp yekupisa pombi.
Bata nesu izvozvi kuti uwane rumwe ruzivo.
