Daikin VRV

Currently, only the R-32 indoor units that have information publicly available are shown. Contact your local Daikin representatives for preliminary information and selections for other R-32 VRV systems. You may use the "R-32" and "R-410A" tabs at the top of the page to toggle between the R-32 and the R-410A lineups. Note that many R-410A systems are approaching or already beyond their last order dates. IMPORTANT: Only R-410A indoor units can be used with R-410A outdoor units, and only R-32 indoor units can be used with R-32 outdoor units. They cannot be mixed and matched.

VRV indoor units should be sized to meet both the cooling and heating load of the zone they are service. Indoor unit nominal capacities, shown in these tables as well as on submittal data sheets, are at AHRI nominal conditions (80/67F EAT in cooling and 70F EAT in heating). These capacities will change as entering air conditions vary. Specifically, cooling capacities tend to drop as the entering wet bulb temperature drops. Work with your Daikin manufacturer's representative and use Daikin WebXpress software to understand the actual capacity of each indoor unit at design condition. Daikin does not de-rate indoor units based on outdoor condition. In heating, select the indoor units assuming the outdoor unit will be sized properly to provide enough heating to all of its fan coils on design day. Then, the outdoor unit selection gets done accordingly to ensure all fan coils are properly fed, even on design day.

First, we generally always recommend pre-treating any outside air with some type of energy recovery unit for energy performance, reduced operational cost, and occupant comfort. In humid regions, or in cold climates, relying solely on VRV indoor units to treat outside air usually results in major energy penalties and occupant comfort issues. Any ducted unit can generally accept any amount of outside air, treated or untreated, as long as the estimated mixed air temperature in both heating and cooling are within the entering air range of the indoor unit (shown in the notes below table on each indoor unit page). Ductless indoor units present more of a challenge. Cassettes do have options for integration of outside air, but normally the amounts allowed are low, and the air needs to be power ventilated into the unit. Pre-treatment of the air is highly recommended for integration with cassettes. Wall mounted, floor mounted and ductless ceiling suspended units do not have any outside air integration options.
