Experimental Assessment of a Domestic Split Type Air-Conditioner Working with R410A

Abstract

The objective of the present work is to assess experimentally the performance characteristics of a R410A domestic air conditioner under different in-door operating conditions. In order to achieve this objective, a test facility of the investigated system is developed and experiments are conducted. Experimental results on R410A air conditioning system are obtained over a wide range of in-door operating conditions. Experimental results confirmed that the cooling capacity, compressor power and COP increase by 90.9%, 5.2% and 81.5%, respectively, as air humidity ratio increases from 8 to 25.5[Formula: see text]gw kg[Formula: see text]. The cooling capacity, condenser heat load, compressor power and COP increase by 7.2%, 6.1%, 2.8% and 4.1%, respectively, when the evaporator air inlet temperature increases from 28[Formula: see text]C to 34[Formula: see text]C for a given humidity ratio. COP increases by 25.6% while pressure ratio decreases by 2.5% as the air volume flow rate increases from 400 to 550[Formula: see text]m3 h[Formula: see text].
