Good day Experts!
I am currently designing a residential VRF system. Since the required indoor temperature is 21C, resulting airflow computed ranges between 600-650 cfm/ton.
Basically, if I select an indoor unit @ medium speed, it will require me to select at 2-3 capacity higher than the computed cooling load. Question, how will I select my outdoor unit? Based on computed cooling capacity? Or based on the selected indoor unit?
If based on cooling capacity, how will the indoor unit or individual zones achieve their desired cooling capacity? Will the outdoor unit distribute the load accordingly based on each individual zone load requirements?
Thank you very much!
