Lintlha tse Khethehileng

Taolo ea kompressor bakeng sa ho aha moea oa moea le moea

Taolo ea lebelo e feto-fetohang ea chiller e u lumella ho fana ka taolo ea khatello e sa feleng ha u ntse u bapisa bokhoni le tlhoko ea 'nete e ipapisitseng le litekanyo tsa sistimi. Taolo ea lebelo e molemo ha konpresser e sebetsa nako e telele e le moroalo o sa fellang. Fokotsa litšenyehelo tsa ts'ebetso ka ho tsamaisa lits'ebetso ka lebelo le tlase le fokotsang tšebeliso ea matla. Le ho fokotsa litšenyehelo tsa ho kenya ka ho ntlafatsa tsamaiso le compressor ka boeona.

Li-drive tsa Danfoss AC li netefatsa hore ho na le ho qala le ho emisa ho fokolang ho fokotsang ho roala ha mochini. 'Me likarolo tse inehetseng, joalo ka ts'ebetso ea 'skip resonance', li u lumella ho tseba habonolo maqhubu ho thibela lerata le tšenyo.

Lihlahisoa tsa li-compressor li kenyelletsa li-starter tse bonolo, li-drive tse matla haholo, li-drive tse tlase tsa harmonic, li-filters tsa AHF tsa harmonic. Li-drive tsohle li tlisoa ka likhetho tsa "cascade controller" tse hahelletsoeng ka hare, li-coil tsa DC le li-controller tsa PID.

E 'ngoe ea lintlha tse kholo ka ho fetisisa tsa litšenyehelo molemong oa bophelo ba sistimi ea ho pholisa ke matla. Lits'ebetsong tse ngata tsa ho futhumatsa le ho etsa sehatsetsi, matla a feta mocheso ka lebaka la ho fapana ha linako tsa selemo, ho kenya lihlahisoa, ho lula hoa maemo a fapaneng, le lisebelisoa tsa motlakase tse bakang tahlehelo ea matla. Li-drive tsa sejoale-joale tse inehetseng tsa AC li lula li fetola matla a sesebelisoa ho ea ho mojaro oa 'nete 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 compressor le condenser/evaporator fan e bohlokoa tsamaisong efe kapa efe e ntlafalitsoeng ea ho pholisa kapa ea sehatsetsi. Ka tloaelo u ka fumana chelete ea 10–25% tšebelisong ea matla ka ho sebelisa li-drive tsa Danfoss AC ho ntlafatsa taolo ea matla a li-compressor tsa sehatsetsi, li-condensers le li-evaporator. Ka ho theha botsitso ha o ntse o leka-lekanya bokhoni ho mojaro oa sebele, tsamaiso-kakaretso ea coefficient of performance (COP) e ntlafatsa ho fana ka chelete ea bohlokoa ea ho boloka matla.

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

Tokiso ea Cascade e hlahisa tšebelisano e ntle lipakeng tsa ts'ebeliso le mochini oa AC ha o laeloa hanyane. Mojaro oa motheo o sebetsanoa ke kopo e le 'ngoe, e kang compressor, e laoloang ke koloi. Ha mocheso o phahama, koloi e qala li-compressor tse eketsehileng ka nako. Sena se tiisa hore lits'ebetso li sebetsa maemong a tsona a ts'ebetso e nepahetseng, 'me koloi e boloka matla a phahameng a matla ho pholletsa le sistimi.

Taolo ea cascade e reriloeng hantle e boetse e tiisa hore ho na le ho fokola ho fokolang lits'ebetsong tsa motho ka mong. Ka ho potoloha li-compressor tse tsamaisoang ke mains-powered, mohlala, batsamaisi ba tlhokomelo ba ka etsa bonnete ba hore e mong le e mong o qetella a e-na le lihora tse tšoanang tsa ho sebetsa le boemo bo lekanang ba ho apara. Sena se eketsa nako ea bophelo ba lits'ebetso mme se eketsa nako ea litšebeletso ho fokotsa litšenyehelo tsa bophelo bohle.

Selaoli se tsoetseng pele sa Danfoss Drives sa Multi-zone pack se netefatsa hore ho na le phokotso e sebetsang le taolo ea lipakete tse ka fihlang ho tse tšeletseng tsa compressor. Sena se fokotsa tšebeliso ea matla, se qoba ho thella khafetsa le ho theola maemo, se tsitsisa likhatello le mocheso, 'me se fokotsa ho senyeha ha compressor. Ka mokhoa o ts'oanang, Pompo ea Cascade Controller e tsamaisa lihora tse tsamaeang ka ho lekana ho lipompo tsohle ho boloka lipompo tsa motho ka mong li sa sebetse.
