CO2-heat pump water heater: characteristics, system design

Abstract. The temperature glide at heat rejection contributes to a very good temperature adaptation when heating tap water, which inherits a large temperature glide. This, together with efficient compression and good heat transfer characteristics of CO 2, makes it possible to design very efficient systems.Cited by: 340Publish Year: 1998Author: Petter Nekså, Håvard Rekstad, G.Reza Zakeri, Per Arne SchiefloeRegulating Characteristics Analysis of Boiler Feed-water https://· According to the characteristics of utility-type generator set in variable load sliding-pressure operation, the paper comprehensively analyzes the features of feed-water system, in which variable-speed main feed-water and power frequency booster-pump connect first in series and then in parallel.Cited by: 5Publish Year: 2012Author: Hu Si-ke, Gao Hui-fen, Jia Xue-jingCharacteristics of boiler feedwater - Answers.comIAN M BARRETT BOILER FEEDWATER Feed water have a low mineral content, a low chloride content, a low dissolved oxygen content and a pH of above 7-8.
