What is the significance of Net Refrigeration Effect (NRE) in HVAC system design?

The Net Refrigeration Effect (NRE) is a critical parameter in HVAC system design as it determines the cooling capacity of a refrigeration system. A well-designed system with a high NRE ensures efficient heat removal, resulting in comfortable indoor temperatures and reduced energy consumption. Conversely, a system with a low NRE may struggle to maintain desired temperatures, leading to occupant discomfort and increased energy bills.
