ShareOptimized design of heat exchangers for "reversible" heat pump using R407C.
Author(s) : BIGOT G., PALANDRE L., CLODIC D.
Summary
Temperature glide of R407C can present either an advantage or a disadvantage depending on the heat exchanger design. There is a need for counter-current heat exchangers whatever the type either air/refrigerant or liquid/refrigerant. For air/water heat pump, perfect counter-current design is possible for liquid/refrigerant heat exchangers whereas crossed current with counter-current tendency design is appropriate for air/refrigerant heat exchangers. The definition of external and internal flow rates permitting the limitation of the mean logarithmic temperature difference is an additional constraint. Tests performed on single row and multiple rows refrigerant/air heat exchangers are presented. Comparisons with R22 performance indicate that higher energy efficiency can be obtained with R407C and appropriate heat exchanger design.
