1. Melao-motheo ea motheo ea sistimi ea sehatsetsing
Ka mora hore sehatsetsi sa metsi se monye mocheso wa ntho e phodiswang ka hara evaporator, se fetoha mouoane ho ba mouoane ka har'a compressor ya sehatsetsi, se hatellwa ho ba mouoane o phahameng le o tlase, ebe se ntshwa ka har'a condenser. Ka har'a condenser, e fepuoa ho ea sebakeng se phodisang (metsi kapa Moea) se lokollang mocheso, se fetoha mouoane o phahameng, se hatellwa ho ba sehatsetsing se tlase le se tlase ke valve ea throttle, ebe se kena ka har'a evaporator hape ho monya mocheso le ho monya, ho fihlela sepheo sa ho hatellwa ka potoloho. Ka tsela ena, sehatsetsi se phethela potoloho ea sehatsetsi ka mekhoa e mene ea motheo ea ho mouoane, ho hatelloa, ho kolobisoa le ho kobeha tsamaisong.
Sistimi ea sehatsetsing, evaporator, condenser, compressor le throttle valve ke likarolo tse 'ne tsa bohlokoa tsa sistimi ea sehatsetsing. Har'a tsona, evaporator ke sesebelisoa se tsamaisang matla a batang. Sehatsetsing se monya mocheso ho tsoa nthong e pholisitsoeng ho fihlela sehatsetsing. Compressor ke pelo 'me se bapala karolo ea ho monya, ho hatella le ho tsamaisa mouoane oa sehatsetsing. Condenser ke sesebelisoa se lokollang mocheso. Se fetisetsa mocheso o monngoang ka har'a evaporator hammoho le mocheso o fetoloang ke mosebetsi oa compressor ho ea setsing sa ho pholisa. Valve ea throttle e phutholla le ho theola khatello ea sehatsetsing, e laola le ho laola bongata ba mokelikeli oa sehatsetsing o phallang ka har'a evaporator, 'me e arola sistimi likarolo tse peli, lehlakore la khatello e phahameng le lehlakore la khatello e tlase. Litsamaisong tsa 'nete tsa sehatsetsing, ho phaella ho likarolo tse' nè tse kholo tse ka holimo, hangata ho na le lisebelisoa tse ling tse thusang, tse kang li-valve tsa solenoid, baabi, li-dryer, li-collectors, li-fusible plugs, li-pressure controllers le likarolo tse ling, tse sebelisetsoang ho ntlafatsa ts'ebetso. E theko e tlaase, e ka tšeptjoa ebile e bolokehile.
2. Molao-motheo oa ho hatsetsa ka mouoane
Sistimi ea ho hatsetsa ea khatello ea mouoane ea mohato o le mong e entsoe ka likarolo tse 'ne tsa motheo: compressor ea ho hatsetsa, condenser, evaporator le valve ea throttle. Li hokahantsoe ka tatellano ke liphaephe ho etsa sistimi e koetsoeng. Sehatsetsi se potoloha ka linako tsohle tsamaisong, se fetola boemo, 'me se fapanyetsana mocheso le lefats'e la kantle.
3. Likarolo tse ka sehloohong tsa sistimi ea sehatsetsing
Diyuniti tsa sehatsetsing di ka arolwa ka mefuta e mmedi ho ya ka sebopeho sa ho kolobisa: diyuniti tsa sehatsetsi tse phodisitsweng ka metsi le diyuniti tsa sehatsetsi tse phodisitsweng ka moya. Ho ya ka morero wa tshebediso, di ka arolwa ka mefuta e mmedi: yuniti e le nngwe ya ho phodisa le mofuta wa sehatsetsi le wa ho futhumatsa. Ho sa tsotelehe hore na ke mofuta ofe o entsweng, e bopilwe ka tse latelang. E bopilwe ka dikarolo tse kgolo.
Sekontiri ke sesebelisoa se lokollang mocheso. Se fetisetsa mocheso o monyelang ka har'a evaporator hammoho le mocheso o fetoloang ke mosebetsi oa compressor ho ea setsing sa ho pholisa. Valve ea throttle e phutholla le ho fokotsa khatello ea sehatsetsing, 'me ka nako e ts'oanang e laola le ho laola bongata ba mokelikeli oa sehatsetsing o phallang ka har'a evaporator, 'me e arola sistimi likarolo tse peli, lehlakore la khatello e phahameng le lehlakore la khatello e tlase.
