Abstract

An experimental study on subcooling process of a transcritical CO₂
air conditioning cycle working with microchannel evaporator was done. In this
cycle there are two different subcoolers namely S1 and S2 were installed and
tested. The experimental data show that the COP of the cycle working with the
subcooler S2 is better which is at 7.2. The evaporator pressure, the subcooler
pressure, the subcooling temperature and the compressor current corresponding
to the above-mentioned COP are 44 bar, 75 bar, 26 ºC, and 2.4 A, respectively. A total
comparison between the present study and other literatures was also indicated
which confirms that the results gained by the present study look better.
