R290, propane, irefrigerant itsva yekuchengetedzwa kwezvakatipoteredza.Inonyanya kushandiswa kupakati pemhepo, kupisa pombi air conditioning, imba yemhepo yemhepo uye zvimwe zviduku zvefiriji michina.Kuchena kwepamusoro R290 inoshandiswa sechinhu chekunzwa tembiricha.Iyo yepamusoro uye yekutanga yekirasi R290 inogona kuva inoshandiswa sefiriji kutsiva R22 neR502, inoenderana neyekutanga sisitimu uye mafuta ekuzora, yepakati air conditioning, kupisa pombi air conditioning, imba yekufemesa mhepo uye zvimwe zvidiki midziyo yefiriji.
Ongororo dzinoratidza kuti uwandu hweperfusion hweR290 pasi peiyo system volume volume inenge 43% yeiyo R22. Sezvo kupisa kwakadzikama kwe vaporization kweR290 kunenge kaviri kune R22, kutenderera kwefiriji yefiriji system uchishandisa R290 idiki zvakanyanya. Uchishandisa R290 refrigerant, simba rekuchengetedza simba rinogona kusvika 10-35%.Iyo R290 "inopisa uye inoputika" chirema chinouraya chinouraya zvakanyanya. R290 inogona kusanganiswa nemhepo kuita musanganiswa unoputika, uri munjodzi yekutsva uye kuputika mukati. kuvapo kwechitubu chekupisa uye moto wakazaruka.
1.Evaporation pressure yakakwirira
Iyo evaporation pressure yakakwirira: kana iyo evaporation pressure yefiriji yakaderera pane yemhepo, mhepo iri nyore kupinda muhurongwa uye hurongwa hwakaoma kubata.Naizvozvo, zvinotarisirwa kuti evaporation pressure yefiriji pazasi tembiricha inogona kuva yakakwirira kudarika mhepo yemuchadenga.
2.The latent kupisa evaporation yakakura
Kupisa kwakadzikama kwe vaporization kwakakura: kupisa kwakadzikama kwe vaporization yefiriji yakakura, zvichiratidza kuti huwandu hwekupisa hunogona kubatwa nekushandisa zvishoma kutonhora.
3.The yakakosha tembiricha yakakwirira
Kana tembiricha yakakosha yakakwira, zvichiratidza kuti tembiricha yefiriji coagulation yakakwira, iyo refrigerant inogona kunyoroveswa nekushandisa ambient air kana mvura kuti iwane mhedzisiro ye condensation liquefaction.
4.The condensation pressure yakaderera
Iyo inotonhorera inotonhora yakaderera: iyo inotonhorera kutonhora yakaderera, zvichiratidza kuti refrigerant inogona kunyungudutswa nekudzika kwakadzika, uye iyo compression ratio ye compressor idiki, inogona kuchengetedza simba rebhiza recompressor.
5.The solidification tembiricha inofanira kunge yakaderera
Tembiricha yechando yakadzikira: nzvimbo yekutonhodza yechando yakadzikira, zvikasadaro inotonhorera inotonhora muevaporator uye haigone kutenderedzwa.
6.The gasi coolant idiki pane vhoriyamu
Iyo chaiyo vhoriyamu yegasi inotonhorera idiki: iyo idiki iyo chaiyo vhoriyamu yemhepo inotonhorera, zviri nani, idiki vhoriyamu yecompressor inogona kuderedza mutengo, uye pombi yekukwevera uye pombi yekuburitsa inogona kushandisa diki inotonhorera yekuparadzira pombi.
7.Liquid inotonhorera ine yakakwira density
Iyo yakanyanya kuwanda kwemvura inotonhorera inotonhorera, iyo inowedzera density yemvura inotonhorera, iyo pombi inogona kuva diki.
8.Soluble mumafuta akaomeswa
Inonyungudika mumafuta akaomeswa nechando: Inonyungudika mumafuta akaomeswa nechando: iyo sisitimu haidi kuisa mafuta anoparadzanisa.
9.Chemical kugadzikana
Kemikari kugadzikana: tembiricha yekubuda inosiyana nekushanduka kwetembiricha, senge tembiricha yekubuda yemuchina wemvura yechando iri 0 ~ 5 ℃, kutonhora mufiriji kutenderera system, inotonhora midhiya inongoshanduka yemuviri, pasina shanduko yemakemikari, kwete kuora.
10.No corrosive
The latent kupisa evaporation yakakura: kwete-corrosive kune simbi uye simbi, uye ammonia corrosive kuti mhangura.Good insulation, kana zvikasadaro achaparadza compressor motokari insulation, saka ammonia haifaniri kushandiswa akavharwa compressor, kuitira kudzivisa zvakananga kusangana. necoil yemhangura.
11.Non - chepfu isingabatiki - inopisa isingaputike
