Cooling Coil (Direct Expansion)
Direct Expansion Cooling Coil Input Dialog
Input Summary:
- Condenser Type : The type of condenser for a Direct Expansion (DX) cooling system. In DX, the options are air and water
- Fuel source : The fuel source of the cooling coil.
- Stages : The number of mechanical cooling stages for a DX cooling coil. This applies to DX systems with more than one stage of DX cooling. This system is typically a packaged unit with multiple compressors and a two-speed or variable-speed fan.
- Net Capacity (Btu/h) : The net total (both sensible and latent) cooling capacity (both sensible and latent) of a cooling coil in unitary system at AHRI conditions. The net capacity is the total cooling capacity of the coil after adjusting for fan heat at rated conditions. The gross capacity is the total cooling capacity without adjustments for fan heat.
- SEER (Input) : The Seasonal Energy Efficiency Ratio (SEER) is a term used to describe the seasonal performance of a DX cooling system. It is determined in accordance with AHRI standards.
- EER (Input) : The cooling efficiency of a DX cooling system at AHRI rated conditions.
- IEER (Input) : The integrated part-load efficiency of a DX cooling system at AHRI rated conditions
