A liquid-to-air heat exchanger was tested to determine the suitability of the system for use in preheating winter ventilation air in livestock confinement buildings. Maximum air temperature rise and heat transfer rate achieved under test conditions were 51.1°C and 86.1 kW, respectively. Relationships were developed to predict heat transfer rate, heat transfer coefficient and exchanger heat transfer effectiveness as functions of inlet air and liquid temperatures, and air and liquid flow rates.
