In air conditioning and refrigeration systems, evaporating heat transfer is crucial. The
most popular substitute refrigerant in refrigeration devices, including air conditioners
and home refrigerators, is HFC 134a. Despite HFC134a's relatively significant potential
for global warming, several nations have confirmed that it is a long-term substitute
refrigerant. The performance of the refrigeration system is enhanced by the addition of
nanoparticles to the refrigerant, which improves the thermophysical and heat transport
characteristics of the refrigerant. In this experiment, CFD heat transfer analysis utilizing
the FLUENT program was used to examine the impact of CuO-R134a in the vapour
compression system on the evaporating heat transfer coefficient. In accordance with
Indian national norms, an experimental equipment was constructed. According to the
experimental research, the nanorefrigerant refrigeration system operates as intended.
Using nano CuO concentrations ranging from 0.05 to 1% and particle sizes ranging
from 10 to 70 nm, heat transfer coefficients were assessed using FLUENT for heat flux
ranging from 10 to 40 kW/m2. The findings show that using nanoCuO enhances the
evaporator heat transfer coefficient.
