Technical Assessment of Advanced Cooling Technologies in the Current Market.
Abstract
This study examined the overall system efficiencies and first costs associated with advanced cooling systems in the current market to provide a tool for estimation of system life cycle costs (LCC) that can be used in selecting systems for a given installation. System first costs and an approach for estimating yearly costs of owning and operating are presented. Energy costs are seen as the central factor in the LCC calculation. A method for comparing the efficiencies of systems rated at different evaporator and condenser temperatures is also provided. With the vapor-compression system as the base line case, sample LCC formulations and calculations for an absorption system and a gas engine driven system are given. Modifications by using unconventional energy supplies, heat sources and sinks are considered. Novel and futuristic systems, and heat pump systems are also reviewed. LCC formulations and calculations for these novel systems were beyond the scope of this study although the methods are given. Both unique application and competing cases are identified.
