Mumakore achangopfuura, kushanda kwesimba uye kuzvipira kwezvakatipoteredza kwakatora kukosha kusati kwamboitika muchikamu chemhepo yekupisa. Chinhu chakakosha mukushanduka uku chave chiri simba remhepo, kupisa uye kutonhora sisitimu inoshandisa mhepo sechitubu chesimba. Muchirevo chechinyorwa chino, R290 refrigerant yakawana mukurumbira nekuda kwekubatsira kwayo kwezvakatipoteredza uye kuita kwakanyanya.
R290, inozivikanwawo se propane, ifiriji yechisikigo iyo iri kuwedzera kushandiswa mumapombi ekupisa uye aerothermal system. Nekudaro, kupisa kwayo kunounza mamwe matambudziko ehunyanzvi uye ekuchengetedza ayo anofanirwa kutariswa kana uchizviita. Muchinyorwa chino chese, tichatarisa zvakadzama kune zvese zvakanakira, kuenzanisa nemamwe mafiriji, uye mirairo inodzora kushandiswa kwayo.
Chii chinonzi R290 refrigerant?
R290 igasi refiriji rechisikigo riri reboka rehydrocarbon. Kuumbwa kwayo kwakanyatso kuchena kwepropane uye inoratidzwa nekuve yakanyatsoshanda refrigerant ine kushoma kwemamiriro ekunze. Nekuda kwezvivakwa izvi, yave imwe nzira inoshanda kune fluorinated magasi echinyakare anoshandiswa mumhepo yekufemesa.
Imwe yemabhenefiti ayo makuru ndeye yakaderera Global Warming Potential (GWP). Nepo mamwe mafiriji, akaita seR32, ane GWP ye675, R290 ine GWP ye3 chete, zvichireva kuti kukanganisa kwayo mukushanduka kwemamiriro ekunze kunenge zero. Uyezve, haina mishonga yakadai seklorini kana fluorine, saka haisi kukuvadza kune ozone layer.
Kuenzanisa pakati peR290 nemamwe mafiriji
Kuti unzwisise zviri nani kukanganiswa kweR290 pane aerothermal simba, zvakakosha kuienzanisa nemamwe mafiriji anoshandiswa zvakanyanya, akadai seR32 uye R410A. Iwe unogona kuwana rumwe ruzivo nezve izvi kuenzanisa mune yedu gwara kune aerothermal brand.
| Zviratidzo | R32 | R290 |
|---|---|---|
| Global warming potential (GWP) | 675 | 3 |
| Infrastructure | Pakati nepakati (A2L) | Pamusoro (A3) |
| Kubudirira kwesimba | Alta | Pamusoro soro |
| Kuenderana nemidziyo iripo | Zvaive zvakanaka kwazvo | Zvingada kugadziriswa |
| Kuwanikwa kwemusika | Wide | Kuwedzera |
Sezvauri kuona, R290 inodarika R32 maererano nekukanganisa kwezvakatipoteredza uye kushanda nesimba. Zvisinei, kupisa kwayo kwakanyanya kunoda mamwe matanho ekuchengetedza, izvo zvinogona kuita kuti kushandiswa kwayo kuve kwakaoma. Kuti uwane mimwe mienzaniso yefriji, unogona kutarisa chikamu chedu chekuongorora pane zvakanakisisa aerothermal systems.
Zvakanakira kushandisa R290 mune aerothermal simba
1. Kushanda kwesimba kwakanyanya: R290 inopa yemhando yepamusoro yekupisa kuita kana ichienzaniswa nemamwe mafiriji, ichibvumira aerothermal masisitimu kuti awane. tembiricha yepamusoro ine simba shoma rinoshandiswa.
2. Kuderera kwezvakatipoteredza: Yayo GWP ye3 inoita kuti ive imwe yemafiriji ane hushamwari hwezvakatipoteredza aripo. Uyezve, nekusava ne fluorine kana chlorine, haina kukanganisa pane ozone layer.
3. Kufambirana kukuru nemamiriro ekunze anodziya: Kusiyana nemamwe mafiriji, R290 inochengetedza kushanda zvakanaka kunyangwe pasi pekumanikidzwa kwakanyanya. yakakwirira ambient tembiricha. Zvakanakira simba reaerothermal mumamiriro ekunze anodziya zviri kuwedzera kuzivikanwa.
4. Kuwedzera hupenyu hwemidziyo: Kuve gasi rakachena, pasina chikonzero chekubatanidza nemamwe makemikari emakemikari, inoderedza kuparara kwemaitiro emukati yemidziyo yeaerothermal.
Kuipa uye matambudziko eR290
Pasinei nemabhenefiti ayo, R290 inewo zvimwe zvinokanganisa. zvipingamupinyi izvo zvakakosha kuyeuka:
1. Kupisa: Yayo A3 flammability classification inoreva kuti inoda yakasimba kuchengetedza matanho. Kana yadonha, inogona kumiririra a njodzi kana matanho akakodzera akasatorwa. Zvakakosha kuziva mabatiro emhando iyi yefiriji.
2. Mitemo yakasimba: Kune mitemo inodzikamisa huwandu hweR290 refrigerant inogona kushandiswa mune mamwe akavharwa masisitimu uye nharaunda, nekuda kwekugona kwayo. ngozi kana ukapukunyuka. Kuti uwane rumwe ruzivo nezve iyi mirau, ona yedu aerothermal mitemo gwara.
3. Kudiwa kwekugadzirisa michina: Kunyangwe ichienderana neakawanda aerothermal masisitimu, kumwe kuisirwa kungangoda zvigadziriso kuti ive nechokwadi chekushanda kwayo uye kuchengeteka.
Mitemo uye kuchengetedza mukushandiswa kweR290
Kushandiswa kweR290 kunodzorwa pamativi ese eEurope uye enyika. Mimwe yemitemo inonyanya kukosha inosanganisira:
- Mutemo (EU) No 517/2014: Inozivikanwa seF-Gas Regulation, inoisa zvirambidzo pakushandiswa kwe fluorinated magasi uye inokurudzira dzimwe nzira dzakasimba dzakaita seR290.
- Standard EN-378:2017: Inogadzirisa iyo firiji yekuchajisa zvisingakwanisi muzvivakwa uye inotangisa mitemo yekuchengetedza pakubata nekuchengetedza.
- Royal Decree 115/2017: Inogadzirisa kushambadzira, kubata uye chitupa chevashandi vanoshanda navo inopisa refrigerant magasi.
Nekuda kwekupisa kwayo, zvinokurudzirwa kuti chete nyanzvi dzakatenderwa dziise nekuchengetedza masisitimu vachishandisa R290. Izvo zvakakosha kuve nechokwadi chekufefetedza kwakaringana uye kutevedzera zvakasimbiswa zvekuchengetedza zvinodiwa. Mugwaro redu rekushandisa aerothermal, unogona kuwana kurudziro pakuisa kwakaringana.
R290 yave iri kuramba ichigoneka uye yakakurumbira sarudzo muchikamu cheaerothermal nekuda kweiyo ecological mabhenefiti uye kugona kwakanyanya. Pasinei ne matambudziko ane chekuita nekupisa kwayo, kutorwa kwayo kunoramba kuchiwedzera. Nekumisikidzwa nekugadzirisa kwakaringana, R290 inogona kuve yakagadzikana uye inoshanda imwe nzira yemhepo yekumisikidza masisitimu nemapombi ekupisa. Mhedzisiro yaro yakanaka mukuderedza kudziya kwepasi inoisa iyo seimwe yeakanakisa sarudzo yeramangwana reanoshanda uye ane mutoro air conditioning.
