Ngezansi amaphuzu okudingeka akhunjulwe lapho ukhetha iyunithi yokushisa yezimboni yomshini wokulamina:
1. Amandla okupholisa eyunithi yokupholisa yezimboni kufanele ahlangabezane nesidingo sokupholisa somshini wokulamina;2. Ukugeleza kwephampu kanye nokuphakamisa iphampu kufanele futhi kuhlangabezane nesidingo;
3.Khetha umenzi we-chiller onomkhiqizo osezingeni eliphezulu kanye nensizakalo esheshayo ngemuva kokuthengisa.
Ngokuphathelene nokukhiqiza, i-S&A Teyu itshale imishini yokukhiqiza engaphezu kwesigidi sama-yuan, iqinisekisa ikhwalithi yochungechunge lwezinqubo kusukela ezingxenyeni eziyinhloko (i-condenser) ye-industrial chiller kuya ekushiseni insimbi; ngokuphathelene nokuthutha, i-S&A Teyu isungule izindawo zokugcina impahla emadolobheni amakhulu aseShayina, njengoba inciphise kakhulu umonakalo obangelwa ukuthutha impahla ibanga elide, futhi ithuthukise ukusebenza kahle kwezokuthutha; ngokuphathelene nensizakalo yangemva kokuthengisa, isikhathi sewaranti siyiminyaka emibili.
