19. Izakhiwo ze-Thermodynamic zika-R134A zisondele kakhulu nalezo ezingama-R12. Usebenzisa u-R134A ukufaka esikhundleni sika-R12 kudinga ukulungiswa okuthile ohlelweni ngoba izakhiwo ezibonakalayo zalokhu zihlukile.
20. Amashubhu wokudlulisa ukushisa we-ammonia condenser ajwayele ukwenziwa ngamashubhu ethusi ngoba i-ammonia nethusi azosabela.
21. I-Amonia inomunyu omuhle wamanzi, kepha emazingeni okushisa aphansi, amanzi azolungisa e-ammonia ketshezi bese eqhwa. Kodwa-ke, okwenzeka ohlelweni akuyona "i-Ice plugging", kepha kungadala ukuvalwa kwamapayipi.
22. Amashubhu ethusi ajwayele ukusetshenziselwa amapayipi esiqandisi esiqandisini e-ammonia afribarey Systems ngoba i-ammonia nethusi azosabela.
23. Kuyiqiniso ukuthi i-freeon ayikhokhisi izinsimbi, kepha iningi lazo lingachithwa emafutheni.
24. Ama-athomu we-chlorine eFreyoni yimbangela eyinhloko yokubhujiswa kwe-amoverric ozone ungqimba, hhayi ama-fluorine.
25
26. Akuwona wonke ama-afriji amasimusi adinga ukufaka owomile. Ziyadingeka kuphela lapho zisebenzisa iziqandisini ezithile kanye ne-Ice blockage kungenzeka zenzeke.
27. Ukufundwa kwegeji yengcindezi kuyingcindezi ehlobene (ingcindezi yegeji), hhayi ingcindezi ngokuphelele.
28. Iphuzu elibilayo loketshezi lihlobene nengcindezi. Ingcindezi ephakeme, ikhuphuka iphuzu elibilayo.
29. Isiqandisi sisezingeni eliphakathi ohlelweni lweqaqa lweqandisi, oluhlukile esiqandisini.
I-30. I-Lesiphirty yinqubo yokwehlisa izinga lokushisa kwesikhala noma into futhi ligcine lokhu kushisa ngezindlela zokufakelwa.
31. Umsebenzi wokwehlukaniswa kawoyela ohlelweni lokuqapha kabusha ukuhlukanisa amafutha okuthambisa kusuka esiqandisini, hhayi ukuvikela amanzi ekuxubeni angena kumafutha okugcoba.
32. I-Evaporator iyithuluzi lokushintshanisa lokushisa elidonsa ukushisa lapho esiqandisini siphuma.
33. Uma uketshezi oluqandisile noma igesi lifudunyezwa kwisilinda, luzokhulisa ingcindezi, lwenze kube nzima ukwandisa nokuthambekela ukuqhuma.
34. I-R134A iyisiqandisi esiphephile. Ukugcoba kwalo akuwona owokumawoyela wamaminerali, kepha owesilisa we-polyeter.
