Abstract

Since global warming has reached critical levels, limitations have
been placed on the use of certain fluoride-containing refrigerants by F-Gas
regulations. The EU F-​​Gas Regulation has introduced quotas for the use of
refrigerants with a global warming potential(GWP) greater than 150. Hydrofluorocarbons(HFCs)
from restricted refrigerants are widely used in heat pump systems. Considering
the environmental impact of these refrigerants, it is important to look for
long-term alternatives to comply with F-gas regulations. Hydrocarbon(HC)
refrigerants are shown as suitable alternatives for heat pump applications. R290
as HC refrigerant is a potential refrigerant suitable for existing HFCs systems
due to zero ODP and low GWP. In heat pump systems, there are many system
components or parameters that are effective in condensing the air passing
through the evaporator. It is very important to know how these elements affect
the condensation performance in different design situations. In this study, the
effect of different parameters such as capillary length, charge amount and
evaporator tube volume on the condensation performance of a R290 hydrocarbon
refrigerant heat pump was investigated by the experimental design approach. The
experimental results obtained was compared with the theoretical model. It has
been determined that the most effective parameter on the condensation
performance is the capillary tube length with the effect of 35%.
