I mea e pale ai i ke kaiapuni, S&Hoʻopiʻi ʻia kahi ʻāpana hoʻoheheʻe wai ʻo Teyu me nā mea hoʻoheheʻe kaiapuni, me R-410a, R-407C a me R-134a. Eia nō naʻe, i ka lawe ʻana i ka ea, pono e hoʻokahe ʻia ka refrigerant, no ka mea, he pahū a pahū ka refrigerant a pāpā ʻia i ka lawe ʻana i ka ea. No laila, ke loaʻa nā mea hoʻohana i ka ʻāpana chiller wai, pono lākou e hoʻopiha hou i ka chiller me ka refrigerant i kuhikuhi ʻia ma ka wahi lawelawe ea air conditioner.
E pili ana i ka hana, S&Ua hoʻolilo ʻo A Teyu i nā lako hana ʻoi aku ma mua o hoʻokahi miliona yuan, e hōʻoiaʻiʻo ana i ka maikaʻi o ke ʻano o nā kaʻina hana mai nā ʻāpana kumu (condenser) o ka chiller ʻoihana a hiki i ke kuʻi ʻana o ka metala; e pili ana i ka logistics, S&Ua hoʻonohonoho ʻo A Teyu i nā hale kūʻai logistic ma nā kūlanakauhale nui o Kina, me ka hoʻohaʻahaʻa nui ʻana i ka pōʻino ma muli o ka logistic lōʻihi o nā waiwai, a me ka hoʻomaikaʻi ʻana i ka lawe ʻana; e pili ana i ka lawelawe ma hope o ke kūʻai aku, ʻelua makahiki ka manawa hoʻohiki.
