6.Effect yekuvaka maitiro
Kushandiswa kwesimba kweHVAC system kunoenderana kwete chete nekuita kwayo uye maparamita ekushanda, asiwo pane hunhu hwekudziya uye kutonhora kudiwa uye thermo inosimba maitiro echivako.Iwo chaiwo mutoro weHVAC masisitimu ishoma pane iyo yakagadzirwa munguva zhinji dzekushanda nekuda kwemaitiro ekuvaka.Naizvozvo, izvo zvakanyanya kukosha zvinokonzeresa kuderedzwa kwesimba rekushandisa kweHVAC muchivakwa chakapihwa kutonga kwakaringana kwekudziya uye kutonhora kudiwa.Kudzora kwakabatanidzwa kwezvivakwa zvekutonhodza zvinhu zvinoremerwa, zvakaita semwaranzi yezuva, mwenje uye mweya mutsva, zvinogona kukonzera kuchengetedza kwakakosha kwesimba muchirimwa chekutonhodza chechivakwa.Zvinofungidzirwa kuti zvinosvika makumi manomwe muzana ekuchengetedza simba zvinogoneka kuburikidza nekushandisa zvirinani dhizaini tekinoroji kuronga kudiwa kwechivako neHVAC system yayo.Korolija et al.yakaongorora hukama pakati pekuvaka kudziyisa uye kutonhora mutoro uye inotevera kushandiswa kwesimba neakasiyana maHVAC masisitimu.Mhedzisiro yavo yakaratidza kuti kuita kwesimba rekuvaka hakugone kuongororwa chete zvichibva pakudziya kwekuvaka uye kutonhora kudiwa nekuda kwekutsamira paHVAC yekupisa hunhu.Huang etal.yakagadziridzwa uye yakaongorora mabasa mashanu ekutonga kwesimba rekutonga akarongwa zvinoenderana nemaitiro ekuvaka uye akashandiswa kune ariabl yemhepo vhoriyamu HVAC system.Mhedzisiro yavo yekufananidza yakaratidza kuti kuchengetedza kwesimba kwe17% kunogona kuwanikwa kana sisitimu ichishandiswa neaya mabasa ekutonga.
Masystems eHVAC akajairika anotsamira zvakanyanya pasimba rinogadzirwa kubva kumafuta ezvicherwa, ari kukurumidza kupera.Izvi pamwe chete nekukura kuri kudiwa kwezvivakwa zvinodhura uye midziyo yemagetsi yave kuda kuisirwa kutsva uye kudzoreredzwa kukuru muzvivakwa zvakagarwa kuti uwane simba resimba uye kuchengetedza kwezvakatipoteredza.Naizvozvo, kutsvaga nzira dzinoverengeka dzekuenda kune zvivakwa zvakasvibirira pasina kukanganisa kunyaradza uye mukati memhepo mhando inoramba iri dambudziko rekutsvaga nekusimudzira.Kudzikiswa kwese kunowanikwa mukushandiswa kwesimba uye kukwidziridzwa kwekunyaradza kwevanhu muzvivakwa zvinoenderana nekuita kweHVAC masisitimu.Imwe nzira yakapupurirwa yekuwana simba rekushandisa muHVAC masisitimu ndeyekugadzira masisitimu anoshandisa novel masisitimu eiyo iripo sisitimu zvikamu.Tsvagiridzo yenguva pfupi yadarika yakaratidza kuti musanganiswa uripo tekinoroji yekufemesa mhepo inogona kupa mhinduro dzinoshanda dzekuchengetedza simba uye kunyaradza kwekupisa.Mubepa rino nzira dzakasiyana dzekuchengetedza simba dzeHVAC masisitimu dzakaongororwa uye kugona kwavo kugadzirisa mashandiro ehurongwa kwakakurukurwa.Zvakaonekwa kuti zvinhu zvakawanda zvakadai semamiriro ekunze, zvinotarisirwa kupisa kunyaradza, mari yekutanga uye mari, kuvapo kwemasimba emagetsi uye kushandiswa.
