Heat Recovery System

This paper presents a CFD Heat Transfer Analysis of an originally designed system for heat recovery in the building sector. The heat exchanger has a dual role, which means it will produce simultaneously hot water and warm air. The key to the efficiency of the heat exchanger is the heat pipe system which recovers thermal energy from residual hot water and transfers it to the secondary agents. The paper includes a case study structured by different mesh distributions and flow regimes. The purpose of the heat exchanger is to reduce the costs of producing thermal energy and to increase the overall energy efficiency of buildings.

Combining with the energy consumption of air-conditioning system and the characteristics of the cooling and heating load in the hotel, the authors analyse the energy-saving property and necessity of adopting condensing heat recovery from water chillers. Taking the air-conditioning system of a star-hotel as an example, the optimization design for condensing heat recovery system from chillers on raising the temperature difference between supply and return water, the hot-water tanks in series and the water temperature stratification effectively realizes cascade and sequential utilization of hot-water, which keeps the water temperature stable and becomes more energy-saving.
