Daikin Heat Recovery Systems for Offices

The Daikin VRV IV Heat Recovery Series stands as one of the most efficient and intelligent HVAC solutions for office buildings.

By reclaiming and redistributing energy within the system, it reduces power consumption dramatically while maintaining precise climate control across multiple zones.

Working Principle

Daikin’s three-pipe heat recovery configuration enables simultaneous heating and cooling.
When one office zone requires cooling, the system captures the extracted heat and delivers it to another area needing heating — effectively recycling energy instead of wasting it.
This allows for substantial reductions in overall power use and carbon footprint.

Performance and Efficiency

• SEER: up to 8.5

• SCOP: up to 5.3

• Energy Class: A+++

• Capacity range: 8 HP – 150 HP

Real-world installations demonstrate 35–45 % annual energy savings compared with standard heat-pump systems.
The system uses R410A refrigerant with future compatibility for R32 low-GWP options.

Zoning and Control

Up to 64 indoor units can connect to one outdoor module via BS (Branch Selector) boxes, allowing each zone to operate independently.
Meeting rooms can be cooled while corridors or north-facing offices are heated — all simultaneously.
Each indoor unit features its own controller, while building managers can supervise operation centrally through Daikin’s Intelligent Touch Manager (iTM).

Smart Integration

The system integrates easily with BMS protocols (BACnet, Modbus, LonWorks) and Daikin Onecta for Wi-Fi control.
Data on temperature, pressure, and refrigerant flow is logged in real time, enabling predictive maintenance and energy analysis.

Noise and Comfort

Indoor units operate at 22–28 dB(A), while outdoor modules in night mode drop to 45 dB(A).
The inverter compressor and fan control ensure smooth modulation, eliminating temperature swings and maintaining comfort with minimal noise.

Environmental Impact

By reusing heat energy internally, Daikin heat recovery systems cut CO₂ emissions by up to 40 % compared with non-recovering VRF models.
All units comply with EU EcoDesign and F-Gas Phase-Down regulations.

Example Application

A 10-floor London office fitted with two VRV IV heat recovery systems achieved a 38 % drop in gas and electricity bills, with ROI reached in 3.2 years.
Occupant comfort scores improved by 18 % in post-installation surveys.

Conclusion

Daikin heat recovery technology provides a practical, sustainable solution for modern offices.
Its simultaneous heating and cooling capability, smart controls, and proven efficiency make it a cornerstone of energy-conscious HVAC design in the UK commercial sector.
