Ukuthetha ngokuthe ngqo, akukho mgangatho ufanayo kakhulu wokubala phakathi komthamo wokupholisa kunye nommandla weamanzi apholisa umoya, kuba kuxhomekeke kwindawo apho i-cooler yomoya isetyenziswa khona. Ngamanye amazwi, idinga umthamo omncinci wokupholisa, kwaye amagumbi aqhelekileyo ahluke kwigumbi lokuhlala. Kwakhona, umzekelo, igumbi elinokuvela entshona kwiindawo ezitshisayo kufuneka linyuse umthamo wokupholisa ngokwentelekiso.

Okwangoku, umthamo wokupholisa oqhelekileyo weamanzi apholisa umoyakwimarike ayingqinelani kakhulu kwaye umgangatho. Ukuthetha ngokuthe ngqo, umthamo wokupholisa wemveliso yamanzi opholileyo kufuneka ubonakaliswe nge-W (watts), kwaye amahashe ahlala esetyenziswa kwimarike ukuchaza amandla okupholisaamanzi apholisa umoya. Ubudlelwane bokuguqulwa phakathi kwezi zibini kukuba: amandla okupholisa i-1 hp malunga ne-2000 kcal, ekufuneka iphindwe nge-1.162 xa iguqulelwe kwiiyunithi zamazwe ngamazwe. Ngale ndlela, umthamo wokupholisa we-1 hp kufuneka ube yi-2000 kcal × 1.162 = 2324W. I-W (watt) apha ithetha amandla okupholisa, kunye nomthamo wokupholisa we-1.5 hp kufuneka ube yi-2000 kcal × 1.5 × 1.162 = 2486W.

Kwiimeko eziqhelekileyo, umthamo wokupholisa ofunekayo ngemitha yesikwere kwigumbi lentsapho eliqhelekileyo li-115-145W, kunye nomthamo wokupholisa ofunekayo ngemitha yesikwere kwigumbi lokuhlala kunye negumbi lokudlela yi-145-175W.

Ngokomzekelo, igumbi lokuhlala losapho linommandla weemitha ezili-15 zesikwere. Ukuba umthamo wokupholisa ofunekayo ngemitha yesikweri nganye yi-160W, umthamo wokupholisa ofunekayo we-cooler yamanzi yamanzi ngu: 160W×15=2400W.

Ngale ndlela, i-XK-20S ifakwe eludongeniamanzi apholisa umoyange-2500W amandla okupholisa anokuthengwa ngokuhambelana nomthamo ofunekayo wokupholisa we-2400W.

Into ebizwa ngokuba yi-eneji yokusebenza kakuhle, ekwaziwa ngokuba yi-coefficient of performance, ngumlinganiselo wesakhono sokupholisa esiqhelekileyo sombane.amanzi apholisa umoyaekusetyenzisweni kwayo kwamandla. Ngesiqhelo, umlinganiselo wokwanelisa amandla omoya opholileyo wamanzi usondele kwi-3 okanye ungaphezulu kwe-3, kwaye yeyomoya opholileyo wamanzi ogcina amandla.

Umzekelo, amandla okupholisa omnyeamanzi apholisa umoyayi-2000W kunye nosetyenziso lwamandla olulinganisiweyo yi-640W, kunye nomthamo wokupholisa kwenye indawo yokupholisa umoya wamanzi yi-2500W kunye nosetyenziso lwamandla olulinganisiweyo yi-970W. Umlinganiselo wokusebenza kakuhle kwamandla we-air conditioners ezimbini ngokulandelanayo: umlinganiselo wokwanelisa amandla omoya opholileyo wamanzi wokuqala: 2000W / 640W = 3.125, kunye nomlinganiselo wokwanela kwamandla omoya opholileyo wesibini: 2500W / 970W = 2.58. Ngale ndlela, ngokuthelekisa umlinganiselo wokonga amandla omoya opholileyo wamanzi amabini, kunokubonwa ukuba i-air conditioner yokuqala sisisonga samanzi esipholileyo samanzi. Inani lokupholisa umoya wamanzi libhekiselele kumandla okufaka umoya opholileyo wamanzi, onxulumene ngokungathanga ngqo kwindawo esebenzisekayo, kwaye ehambelana ngqo nommandla osebenzisekayo ngumthamo wokupholisa. Kwilizwe lam, umthamo wokupholisa omnye wamanzi opholileyo ngokuqhelekileyo malunga ne-2300W. Kukho umahluko kubungakanani.

Uyilo olupholileyo lomoya lwamanzi luyilwe ngokweecubic metres yendawo, oko kukuthi, imitha enye ye-cubic inomthamo wokupholisa we-50W, kwaye abathengi banokubala indawo esebenzayo yokupholisa umoya wamanzi ngokobude bezindlu zabo.

Umzekelo: ihanger enye, amandla okupholisa ngama-2300W

Umthamo wayo osebenzayo ngu-2300/50=46 cubic metres

Ukuba ubude begumbi buziimitha ezi-3, indawo esebenzayo yi-46/3 = 15.3 square metres.

Xa ukhetha, ukuqhelaniswa kwendlu kunye nokuba kumgangatho ophezulu kufuneka kuqwalaselwe. Umthamo wokupholisa kufuneka unyuswe ngokufanelekileyo kumgangatho ophezulu. Kucetyiswa ukuba ukhethe i-2500W.
