Compressor sizing using R404a
Hi all,
I would like to seek advise on sizing the reciprocating compressor (Carlyle brand). Base on the Heat Load Calculation, the sensible and latent heat gain is about 100kW. Using the psychrometric chart, my required cooling capacity is about 300kW.
I have problem trying to determine refrigerant data such as, the Saturated suction temperature, liquid temperature before and after condenser etc temp related data.
I assume I would need these data to determine the mass flow of refrigerant and in order to determine the size of the compressor.
I have tried using the Carwin software for compressor sizing, however the software required the temperature data to size the compressor too.
Please advise. Many thanks.
