Design and Performance of Heat Pipe Air-Conditioning Based on Latent Heat of Water Evaporation

This paper proposes a scheme for creating low-pressure environment to evaporate large amount of water, using the latent heat water evaporation cooling, designing and building test bench pipe air conditioning system, testing working performance negative pressure evaporating conditioner at 30–85°C. COMSOL Multiphysics Establish fluid transfer model analyze internal transfer. Under design condition 40°C, EER is 2.1 cooling capacity 298W. The experimental data results show that system in high-efficiency range 50–75°C 2.5, maximum 376W, actual application temperature 30–40°C 1.4, 221.6W. Basically reached index can run stably.
