Daikin VRV IV RXYQ16U 45 kW Outdoor Air Conditioning Unit

Daikin RXYQ16U 45 kW

The Daikin RXYQ16U is a high-capacity VRV IV+ outdoor heat-pump unit designed for commercial and large-scale multi-zone heating and cooling applications.

With a 45.0 kW nominal cooling capacity and 50.0 kW nominal heating capacity, the RXYQ16U provides the capacity required for demanding commercial HVAC installations. Daikin’s European VRV catalogue identifies the RXYQ16U as a 16 HP outdoor unit in the RXYQ-U range.

The system is designed for professional HVAC applications where multiple indoor units and individually controlled zones are required.

45 kW Commercial VRV Air Conditioning

The RXYQ16U provides:

• 45.0 kW nominal cooling capacity
• 50.0 kW nominal heating capacity
• 16 HP capacity class
• VRV IV+ heat-pump technology
• Multi-zone commercial climate control
• European technical documentation
• R-410A refrigerant for this VRV IV+ generation

Daikin’s European catalogue confirms the 45.0 kW cooling and 50.0 kW heating ratings for the RXYQ16U.

Daikin VRV IV+ Heat Pump Technology

The RXYQ-U series is part of Daikin’s VRV IV+ heat-pump range.

Daikin developed VRV IV+ with technologies intended to improve efficiency, especially during partial-load operation. The range incorporates Variable Refrigerant Temperature control and inverter compressor technology.

This makes the RXYQ16U suitable for projects where efficient centralized heating and cooling are required across multiple zones.

Designed for Commercial HVAC Projects

Unlike residential split air conditioners, the RXYQ16U is intended for larger HVAC installations.

Potential applications include:

• Office buildings
• Hotels
• Retail properties
• Commercial developments
• Schools and educational facilities
• Healthcare buildings
• Apartment developments
• Mixed-use buildings
• Large residential projects
• Hospitality projects
• Renovation projects
• Commercial HVAC replacement projects

The exact suitability of the system should be established through professional HVAC design and heat-load calculations.

Daikin VRV Multi-Zone Climate Control

VRV technology allows a single outdoor system to serve multiple indoor units and zones.

Daikin’s VRV documentation provides indoor-unit connection information and system capacity ranges for the RXYQ-U platform. For the RXYQ16U, the catalogue lists an indoor-unit index connection range of 200 / 400 / 520 and up to 64 connected indoor units within the relevant system configuration.

The final number and combination of indoor units must be designed according to Daikin’s approved combination rules and the requirements of the project.

45 kW Cooling Capacity

The RXYQ16U has a nominal cooling capacity of 45.0 kW.

This makes it suitable for commercial projects requiring substantial cooling capacity from a VRV outdoor unit.

The appropriate system capacity should always be calculated by a qualified HVAC designer based on factors such as:

• Building size
• Occupancy
• Solar gain
• Insulation
• Glazing
• Internal heat loads
• Climate
• Required indoor temperatures
• Building usage

50 kW Heating Capacity

The RXYQ16U provides a nominal heating capacity of 50.0 kW according to Daikin’s European RXYQ-U documentation.

This allows the VRV system to provide both heating and cooling from the same outdoor platform, making it suitable for buildings requiring year-round climate control.

Variable Refrigerant Temperature Control

One of the technologies associated with Daikin’s VRV IV+ platform is Variable Refrigerant Temperature control.

This technology is designed to optimize refrigerant temperature according to operating requirements, helping improve seasonal efficiency and comfort compared with conventional fixed refrigerant-temperature operation. Daikin identifies Variable Refrigerant Temperature and inverter compressors among the VRV IV+ technologies.

Inverter Compressor Technology

The RXYQ-U platform uses inverter compressor technology.

Inverter operation allows the system to adjust capacity according to demand rather than continuously operating at a fixed output.

This is particularly useful in commercial buildings where heating and cooling requirements can change throughout the day.

RXYQ16U Dimensions and Weight

The European Daikin catalogue lists the RXYQ16U outdoor unit at approximately:

1,685 mm high × 1,240 mm wide × 765 mm deep

The RXYQ16U is listed at approximately 275 kg in the European RXYQ-U catalogue.

Because of its size and weight, installation planning should include suitable access, lifting equipment, structural support and service clearances.

R-410A Refrigerant

The RXYQ-U VRV IV+ generation uses R-410A refrigerant. European technical information for the RXYQ16U identifies R-410A as the refrigerant used by this generation.

Because refrigerants and F-Gas requirements are regulated in Europe, installation, refrigerant handling, commissioning and servicing should be carried out by appropriately qualified professionals and in accordance with applicable regulations.
