Fully Fresh Air Air-conditioning System Equipped with Double Heat Pipe Based Heat Recovery Technology

The using of double heat pipe based heat exchanger (HPHX) in a conventional fully fresh air air-conditioning (AC) system was examined in the present study. The fabricated HPHXs were tested under the actual conditions and the measured data were used to study the performance of the existing AC system (System A) and AC system equipped with the double HPHX (System B) for a yearly operation through ...

Energy-Efficient Air-Cooled DX Air-Conditioning Systems with Liquid Pressure Amplification

The objective of this study is to explore an optimal strategy on energy consumption for a direct expansion (DX) air-conditioning system by using a refrigerant pump in the liquid line to allow the system to operate at a lower condensing pressure. An existing DX rooftop package of a commercial building located in a hot and dry climate zone is used for data collection. The theoretical-empirical mo...

Study On Energy Efficient Operation of Air-conditioning Cooling Water System

The control logic of frequency adjustment for pump and cooling tower fan has been presented in this paper, based on the operation mode of a chiller with one pump and one cooling tower. Optimum outlet water temperature control of cooing tower has been put forward through analysis and comparison among factors influencing it based on measured data. A mathematical model of energy consumption has be...
