Techno-Economic Analysis of Air-to-Water Heat Rejection Systems
Abstract
The challenge of an effective heat rejection is a key problem in air-conditioning design. Air-based heat rejection systems are the most widespread technologies in cooling applications, but even though these provide a mature technology, a better knowledge of products available on market is desirable in order to support design phases. In this paper a market survey on more than 1300 systems has been carried out within the activities of Task 48 of the International Energy Agency. The result has the form of a database and the collected data have been used for conducting a technical, energetic and economic comparison. A set of performance figures and dimensionless parameters has permitted to characterize heat transfer phenomena for different system technologies. A crosscheck with previous literature works has guaranteed the soundness of the outcomes.
