Abstract:

A pump-driven heat pipe loop device was proposed for recycling energy from exhaust air and reducing energy consumption of processing fresh air in air-conditioning systems of public buildings. An experimental setup was built to investigate performances of such device under summer and winter working conditions. Through the study on effect of mass flow rate, heat exchange area and headwind velocity to heat transfer rate, temperature efficiency and coefficient of performance (COP), the optimum mass flow rate, heat exchange area and headwind velocity were obtained. Under summer working condition, the device had achieved the heat transfer rate of 4.09 kW and the COP of 9.26 at the mass flow rate of 250 kg·h^-1, the heat exchange area of 58.0 m² and the headwind velocity of 1.8 m·s^-1. Under winter working condition, the device had achieved the heat transfer rate of 6.63 kW and the COP of 14.20 at the mass flow rate of 300 kg·h^-1, the heat exchange area of 58.0 m² and the headwind velocity of 1.8 m·s^-1.

Key words: pump-driven heat pipe loop, energy recycle, mass flow rate, heat exchange area, headwind velocity
