Performance of R-22 Alternative Refrigerants in a System With Cross-Flow and Counter-Flow Heat Exchangers (Classic Reprint) - Softcover

Inhaltsangabe

Explore practical comparisons of refrigerants for residential heat pumps and learn how real-world testing shapes choices. This study experimentally evaluates several hydrofluorocarbon refrigerants as replacements for R-22 in a small, breadboard-style heat pump. It covers cooling and heating performance, different configurations, and how factors like superheat and subcooling affect efficiency and capacity.

This edition details the experimental setup, the range of tested fluids, and how measurements like capacity and COP were obtained. It presents findings on how zeotropic mixtures and single-component refrigerants perform under varied conditions, including the impact of a liquid-line/suction-line heat exchanger. The results offer practical context for selecting refrigerants in residential heat pump design and retrofits.

• Hands-on look at a compact heating/cooling test rig and how it mirrors real systems


• Comparisons among R-22 alternatives: R-134a, R-32/134a, R-407C, and R-410A


• Insights on how superheat, subcooling, and heat-exchanger configurations influence COP and capacity


• Discussion of how charge, oil compatibility, and system layout affect performance

Ideal for readers of technical studies on refrigerants and HVAC system performance, and professionals evaluating replacement options for aging systems.
