Mashandiro anoita tekinoroji ye "Variable Refrigerant Flow"
Pendauluan
Munyika yanhasi iri kuchinja nekukurumidza, kudiwa kwekunyaradzwa uye kushanda zvakanaka kwesimba mumagetsi emhepo kwakatungamira kukura kwemhando dzakasiyana dzematekinoroji epamusoro. Imwe tekinoroji iri kuramba ichizivikanwa ndeyeVariable Refrigerant Flow (VRF). Iyi tekinoroji inopa mhinduro inochinjika, inoshanda zvakanaka, uye yakasununguka kana tichienzanisa nehurongwa hwemazuva ano hweHVAC (Heating, Ventilation, and Air Conditioning). Chinyorwa chino chichatsanangura zvakadzama mashandiro anoita tekinoroji yeVRF, kusanganisira misimboti yayo yekutanga, zvikamu zvakakosha, uye zvakanakira zvayo.
Nheyo dzekutanga dzeVRF Technology
Variable Refrigerant Flow, kana kuti VRF, isystem yeHVAC inodzora huwandu hwerefrigerant inoendeswa kumayuniti akasiyana-siyana mukati meyuniti imwe chete zvichienderana nezvinodiwa nekupisa kwemukamuri yega yega. Iyi tekinoroji yakagadzirwa kugadzirisa matambudziko ekushaya simba kwesimba anowanzo sangana nawo mumasystem eHVAC akajairwa, ayo anowanzo shanda nechiyero chakatarwa pasina kufunga nezvekuchinja kwemitengo yekutonhodza kana yekudziya.
Nheyo huru yeVRF ndeyekudzora kuyerera kwerefrigerant uye kumhanya kwecompressor zvakasiyana-siyana, zvichibvumira sisitimu kugadzirisa kubuda kwayo kuti ienderane nezvinodiwa nekupisa kwekamuri rega rega. Nenzira iyi, VRF inogona kuvandudza mashandiro esimba uye kunyaradzwa kwevashandisi.
Zvikamu Zvikuru muVRF System
Chikamu cheCompressor neCondenser
Chikamu checompressor necondenser ndicho chiri pakati peVRF system. Compressor inodzvanya refrigerant, ichiishandura kuita gasi rine simba rekupisa kwakanyanya. Refrigerant inobva yayerera nemucondenser, uko kupisa kwayo kunobviswa uye refrigerant inodzokera kumamiriro ayo emvura.
Mumasystem eVRF, compressor inowanzova rudzi rweinverter, iyo inogona kushandura kumhanya kwayo kwekutenderera zvichienderana nezvinodiwa zvekutonhodza kana kudziya. Izvi zvakasiyana nemasystem eHVAC akajairwa, ayo anowanzo shandisa macompressor ane kumhanya kwakagadzika.
Pipe yeRefrigerant
Mapaipi emufiriji anoshanda senzira yekufambisa refrigerant pakati pecompressor/condenser unit ne evaporator unit iri mumakamuri akasiyana-siyana kana nzvimbo dzakasiyana. Mapaipi aya anofanira kugadzirwa kuderedza kudonha kwemvura uye kurasikirwa nekumanikidzwa.
Chigadziko cheEvaporator
Chigadziko che evaporator chinhu chinoiswa mukati mekamuri kana nzvimbo inofanira kugadziriswa. Chigadziko ichi chinoshanda kuti chitore kupisa kubva mumhepo yemukati, zvichiita kuti kutonhore. Izvi zvinoitika kana firiji yapwa mu evaporator, ichitora kupisa kubva mumhepo yakapoteredza.
Mutongi uye Sensor
Masisitimu eVRF anovimba zvakanyanya nemasensa akasiyana-siyana uye macontroller kuti adzore kuyerera kwerefrigerant uye kumhanya kwecompressor. Masensa aya anopa ruzivo nezve tembiricha, kumanikidzwa, uye hunyoro munzvimbo dzakasiyana-siyana mukati mesisitimu. Mutongi anoshandisa ruzivo urwu kugadzirisa mashandiro emavharuvhu ekudzora kuyerera kwecompressor uye refrigerant munguva chaiyo.
Vharuvhu Yekudzora Kuyerera
Mavharuvhu ekudzora kuyerera kwemvura anodzora huwandu hwerefrigerant inoyerera ichienda kuyuniti yega yega ye evaporator. Muhurongwa hweVRF, mavharuvhu aya anodzorwa necentral controller zvichibva padata rakatorwa kubva kumasensa akasiyana-siyana.
Mashandiro eVRF Systems
Mutemo weKuyerera kweRefrigerant
Masisitimu eVRF anoshandisa mavharuvhu ekudzora kuyerera kwemvura kudzora huwandu hwerefrigerant inounzwa kuyuniti yega yega ye evaporator. Izvi zvinobvumira mayuniti e evaporator kushanda ega, achichinja zvinoenderana nezvinodiwa nekupisa kwemukamuri yega yega kana nzvimbo. Semuenzaniso, kana imwe kamuri ichida kutonhodza kupfuura imwe, VRF system inogona kuendesa refrigerant yakawanda kuyuniti ye evaporator iri mukamuri iyoyo.
Kumhanya kweCompressor Kunoshanduka
Imwe mukana weVRF system kugona kudzora kumhanya kwecompressor. Inverter compressor inogona kushandura kumhanya kwayo zvichienderana nezvinodiwa zvekutonhodza kana kupisa zvakaverengerwa necentral controller. Nenzira iyi, compressor haifanirwe kumhanya nekumhanya kwakazara nguva dzese, izvo zvinochengetedza simba uye zvinoderedza kupera simba pacompressor.
Kudzora Kwakabatana
Masisitimu eVRF ane masystem akabatanidzwa anotarisa nekugadzirisa maparameter ekushanda panguva chaiyo. Masensa ari musystem yese anotumira data pamusoro pekupisa, kumanikidzwa, uye hunyoro kune central controller. Iyi controller inozogadzirisa data uye inoita shanduko dzinodiwa, dzakadai sekuchinja kumhanya kwecompressor kana mavharuvhu ekuvhura/kuvhara ekudzora kuyerera.
Kupisa uye Kutonhodza Panguva Imwe Chete
Chimwe chezvinhu zvepamusoro zveVRF systems kugona kwavo kupa kupisa nekutonhodza panguva imwe chete munzvimbo dzakasiyana-siyana. Izvi zvinobvumira chikamu chimwe chechivako kutonhodzwa nepo chimwe chikamu chichidziiswa, zvichienderana nezvinodiwa nemunhu mumwe nemumwe. Iyi tekinoroji inonyanya kubatsira muzvivakwa zvikuru zvine zvinodiwa zvakasiyana-siyana zvekupisa munzvimbo dzakasiyana-siyana, zvakaita semahotera, mahofisi, uye nzvimbo dzekutenga.
Mabhenefiti eVRF Technology
Efisiensi Energi
Chimwe chezvakanakira zvikuru zvemasystem eVRF ndechekuti anoshanda nesimba zvakanyanya. Kugona kudzora kuyerera kwerefrigerant uye kumhanya kwecompressor zvinobvumira system kushanda zvakanaka kupfuura masystem eHVAC. Zvidzidzo zvinoratidza kuti masystem eVRF anogona kuchengetedza simba rinosvika 30-40% zvichienzaniswa nemasystem ekare.
Kunyaradzwa Kwakakwirira
Nekukwanisa kudzora tembiricha munzvimbo dzakasiyana, masisitimu eVRF anopa nyaradzo yakakura kune vanogara muchivako. Hapana chikonzero chekunetseka nezvenzvimbo "dzinopisa" kana "dzinotonhora" mukamuri, sezvo kamuri rega rega richigona kugadziriswa kuti rienderane nezvinodiwa nemushandisi waro.
Kuchinjika uye Kugona Kukura
Masisitimu eVRF anochinjika zvakanyanya uye anogona kukura. Izvi zvinoreva kuti anogona kuwedzerwa kana kugadziriswa zviri nyore kuti aenderane nezvinodiwa nechivako. Mamwe mayuniti anogona kuwedzerwa pasina chikonzero chekugadzirisa kana kutsiva sisitimu yese, zvichiita kuti ive yakakodzera zvivakwa zviri kuramba zvichikura kana kuti zvichichinja mashandisirwo.
Dhizaini Yakamanikana
Masisitimu eVRF ane dhizaini diki zvichienzaniswa nemasisitimu eHVAC akajairwa, ayo anoda mapaipi makuru uye anowanzo kuve akaomarara. Izvi zvinoita kuti masisitimu eVRF ave nyore kuisa uye anochengetedza nzvimbo mukati mezvivakwa.
Mhedziso
Tekinoroji yeVariable Refrigerant Flow (VRF) inopa mhinduro inochinjika, inoshanda nesimba, uye yakasununguka zvichienzaniswa nehurongwa hweHVAC hwemazuva ano. Nekukwanisa kudzora kuyerera kwerefrigerant uye kumhanya kwecompressor zvakasiyana-siyana, tekinoroji iyi inogadzirisa mashandiro ayo zvichienderana nezvinodiwa nekupisa kwekamuri rega rega kana nzvimbo panguva chaiyo. Zvimwe zvakanakira zvinosanganisira kushanda nesimba, kunyaradzwa kwakawedzerwa, kuchinjika, uye dhizaini diki, zvichiita kuti VRF ive sarudzo yakakodzera kune akasiyana mashandisirwo, kubva kuzvivakwa zvemabhizinesi kusvika kune zvekugara. Sezvo tekinoroji ichifambira mberi uye kudiwa kwesimba rakawanda kuri kuramba kuchienderera mberi, VRF inotarisirwa kuramba iri sarudzo inozivikanwa mumasisitimu emhepo anotonhodza mune ramangwana.
