Experimental evaluation of local air temperature and heat transfer of a serpentine copper pipe heat exchanger.

Central air conditioning systems are employed to regulate air quality to an ideal level. Nevertheless, these systems can consume a significant quantity of energy when tasked with conditioning a sizable area. The aim of this project was to manage the ambient air temperature in the vicinity of a plantation area, and a cooling serpentine copper pipe heat exchanger was established. Furthermore, an analysis of heat transfer and the local air temperature distribution in the surrounding area was carried out. Results indicated that the cooling serpentine heat exchanger effectively lowered indoor local air temperatures below those of ambient air. The local air temperature was notably influenced by the inlet water temperature when the volume flow rate remained constant. The local air temperatures experienced a decrease ranging from 5 °C to 9 °C. Additionally, it is evident that both volume and temperature of water flowing through the system had significant impacts on heat flux, condensation, and convection heat transfer.
