Taolo ea compressor bakeng sa moea o kenang ka har'a moaho le moea o pholileng

Taolo e feto-fetohang ea lebelo la chiller e u lumella ho fana ka taolo ea khatello e sa khaotseng ha u ntse u bapisa bokhoni le tlhoko ea 'nete ho latela litekanyo tse tsamaisong. Taolo ea lebelo e molemo ha compressor e sebetsa nako e telele ka mojaro o sa fellang. Fokotsa litšenyehelo tsa ts'ebetso ka ho sebelisa lits'ebetso ka lebelo le tlase le fokotsang tšebeliso ea matla. Le ho fokotsa litšenyehelo tsa ho kenya ka ho ntlafatsa sistimi le compressor ka boeona.

Di-drive tsa Danfoss AC di etsa bonnete ba hore ho qala le ho emisa ho fokolang, e leng se fokotsang tshenyo ya mechine. Mme dikarolo tse ikgethileng, jwalo ka mosebetsi wa 'skip resonance', di o dumella ho hlwaya habonolo maqhubu a drive ho thibela lerata le tshenyo.

Lihlahisoa tsa li-compressor li kenyelletsa li-starter tse bonolo, li-drive tse matla a phahameng, li-drive tse tlase tsa harmonic, li-filter tsa harmonic tsa AHF. Li-drive tsohle li tlisoa ka likhetho tsa taolo ea cascade tse hahiloeng kahare, li-coil tsa DC le li-controller tsa PID.

E 'ngoe ea mabaka a maholo ka ho fetisisa a litšenyehelo potolohong ea bophelo ba sistimi ea ho pholisa ke matla. Lits'ebetsong tse ngata tsa ho pholisa le tsa sehatsetsing, matla a feta mojaro oa mocheso ka lebaka la liphetoho tsa linako tsa selemo, ho jara lihlahisoa, liphetoho tsa ho ba teng ha tsona, le lisebelisoa tsa motlakase tse bakang tahlehelo ea motlakase. Li-drive tsa sejoale-joale tse inehetseng tsa AC li lula li fetola bokhoni ba lisebelisoa ho latela mojaro oa mocheso le litlhoko tsa ts'ebetso. Melemo ke tšebeliso e tlase haholo ea matla le litšenyehelo tse tlase tsa ts'ebetso le tlhokomelo.

Taolo e bohlale ea fene ea compressor le condenser/evaporator ke ea bohlokoa tsamaisong efe kapa efe e ntlafalitsoeng ea ho pholisa kapa ea sehatsetsing. Hangata u ka fihlella poloko ea 10-25% tšebelisong ea matla ka ho sebelisa li-drive tsa Danfoss AC ho ntlafatsa taolo ea bokhoni ba li-compressor tsa sehatsetsing, li-condenser le li-evaporator. Ka ho theha botsitso ha u ntse u leka-lekanya bokhoni le mojaro oa 'nete, coefficient ea ts'ebetso ea sistimi ka bophara (COP) e ntlafatsa ho fana ka poloko e kholo ea matla.

Taolo ea Cascade e ntlafatsa poloko ea matla le ho fokotsa litšenyehelo tsa potoloho ea bophelo

Tlhophiso ea Cascade e hlahisa tšebelisano e ntle ka ho fetisisa pakeng tsa sesebelisoa le drive ea AC tlas'a ho jarisoa karolo. Mojaro oa motheo o sebetsoa ke sesebelisoa se le seng, joalo ka compressor, e laoloang ke drive. Ha mojaro oa mocheso o phahama, drive e qala li-compressor tse ling ka bonngoe. Sena se netefatsa hore lits'ebetso li sebetsa sebakeng sa tsona se setle sa ts'ebetso, 'me drive e boloka ts'ebetso e phahameng ka ho fetisisa ea matla tsamaisong eohle.

Taolo e reriloeng hantle ea cascade e boetse e netefatsa hore ts'ebetso ka 'ngoe e na le ts'enyeho e fokolang. Ka ho potoloha li-compressor tse tsamaisoang ke motlakase, mohlala, batsamaisi ba tlhokomelo ba ka netefatsa hore e 'ngoe le e 'ngoe e qetella e e-na le lihora tse ts'oanang tsa ts'ebetso le boemo bo lekanang ba ts'enyeho. Sena se eketsa nako ea ts'ebetso ea ts'ebetso 'me se atolosa linako tsa ts'ebeletso ho fokotsa litšenyehelo tsa potoloho ea bophelo.

Taolo e tsoetseng pele ea liphutheloana tsa Danfoss Drives e netefatsa ho theoha le ho laola liphutheloana tse fihlang ho tse tšeletseng tsa compressor ka katleho. Sena se fokotsa tšebeliso ea matla, se qoba ho beha le ho theola liphutheloana khafetsa, se tsitsisa likhatello le mocheso, 'me se fokotsa ho senyeha le ho taboha ha compressor. Ka mokhoa o ts'oanang, Pump Cascade Controller e aba lihora tsa ho sebetsa ka ho lekana ho pholletsa le lipompo tsohle ho boloka ho senyeha le ho taboha ha lipompo ka bonngoe ho le tlase.
