Engineers select units from the Daikin air cooled chiller catalogue by first determining the required cooling capacity and efficiency targets. The official documentation lists performance data for the EWAD series across various ambient conditions.
Proper matching prevents oversizing and reduces operational costs over the equipment lifetime. Site constraints such as available electrical supply and clearance dimensions must also be reviewed during this phase.
Daikin EWAD Chiller Catalogue Data Access
Engineers begin the selection process by gathering the latest Daikin air cooled chiller catalogue along with project design parameters. This step ensures access to accurate capacity tables, efficiency curves, and dimensional drawings for the EWAD series. Cross checking these resources against local codes avoids later revisions during permitting. The catalogue also contains refrigerant charge estimates and sound power data that influence equipment placement decisions.
Daikin selection software forms the core tool in this assembly. Print specification sheets for candidate models before proceeding further.

Daikin Chiller Structural Support and Clearances
Site teams must confirm all safety requirements listed in the Daikin installation manual before any equipment arrives. This includes verifying structural support ratings for the chiller weight and ensuring adequate service clearances around the unit. Electrical disconnects require proper sizing according to the nameplate data supplied in the catalogue. Refrigerant leak detection systems should be planned where local regulations demand them.
Install lockout devices on all power sources during initial setup. Review pressure relief valve locations on the selected model.
Daikin EWAD Capacity Matching Steps
The core engineering task involves entering design conditions into the Daikin selection program to generate viable EWAD options. Start with the calculated cooling load and apply the design wet bulb or dry bulb temperature to narrow the field. Efficiency ratings at part load conditions receive equal weight because most installations operate below full capacity for extended periods. Footprint and weight data then eliminate units that exceed available space or roof loading limits.
Record three candidate models that satisfy both capacity and efficiency thresholds. Compare refrigerant volumes across the short list to identify the lowest charge option.
EWAD Range Electrical Supply Parameters
Power requirements vary across the EWAD range and must align with available site infrastructure. Begin by extracting full load amperage and starting current values directly from the catalogue data sheets. Add allowances for control transformers and any accessory pumps or fans that share the same circuit. Voltage drop calculations over the feeder length prevent nuisance trips during compressor start up.
Size the disconnect switch to handle at least 115 percent of the nameplate current. Coordinate with the utility for any required transformer upgrades.
Daikin EWAD Series Octave Band Data
Sound levels listed in the Daikin catalogue guide final unit placement and possible attenuation measures. Review octave band data rather than single A weighted numbers to predict community impact accurately. Low noise versions of the EWAD series incorporate compressor enclosures and fan speed controls that reduce radiated sound by several decibels. Compare these options against local ordinances before finalizing the model.
Order optional compressor blankets when the base unit exceeds night time limits. Position the chiller away from sensitive receptors during layout planning.
Compare Available Heat Recovery Models
Certain EWAD configurations offer partial or full heat recovery that can offset domestic hot water or heating loads. The catalogue provides entering and leaving water temperatures along with recovered heat quantities at various cooling capacities. Evaluate the economic return by comparing recovered energy value against the added first cost of the heat exchanger bundle. Not every project justifies this feature, so limit consideration to sites with consistent simultaneous heating demand.
Model annual energy savings using local utility rates. Select the heat recovery package only when payback falls inside the project financial criteria.
Daikin Chiller Requisition Lead Time Confirmation
Final documentation packages the chosen model number, options, and accessories into a formal purchase requisition. Include all performance guarantees and spare parts recommendations extracted from the Daikin catalogue. Confirm lead times and shipping weights to coordinate crane and pad preparation on site.
Forward the complete submittal to the mechanical contractor for coordination. Schedule factory startup service at the time of order placement.
