Heat exchange, energy conservation, while smoke, exhaust to enhance indoor air circulation effect

The HRV series ventilates and recovers heat energy lost through ventilation. It holds down room temperature changes caused by ventilation, thereby maintaining a high-air-quality environment. The series includes the VKM-GAM models, equipped with a DX-coil and humidifier, to provide further advanced features. Furthermore, it can be interlocked to Daikin's VRV systems and other air conditioning systems

Using a single system

Air conditioning and outdoor air processing can be accomplished using a single system.

Daikin's cutting-edge technologies

Operation of the heat exchanger element

Heating and humidification process

The Outdoor air is heated from 16.6°C to 36.5°C with DX-coil, Natural Evaporating Pan Type Humidifier is passed and humidification capacity is improved.

Heat exchanger and cooling/heating operation

Indoor unit with outdoor air treatment

Using outdoor air, the temperature can be brought near room temperature with minimal cooling capacity through the use of outdoor air.

Interlocking functionality

Daikin's HRV is interlocked to Daikin's VRV and other air conditioning systems and automatically switches over ventilation mode. HRV operation has been centralised into the air conditioner remote controller, giving you total control over to air conditioning and ventilation through a simple configuration

Reduced air conditioning load 

Total heat exchange ventilation

This unit recovers heat energy lost through ventilation and curbs room temperature changes caused by ventilation, thereby conserving energy and reducing the load on the air conditioning system.

Enthalpy efficiency drastically improved by employing thin film element! (VAM-GJ model)

Due to the thinner film... Decreases the moisture resistance of the partition sheets drastically.Realises more space for extra layers in the element, resulting in increased effective area that supply and exhaust air can be exposed to.Moisture absorption increased by approx. 10%! 

Auto-ventilation Mode Changeover Switching

Automatically switches the ventilation mode (Total Heat Exchange Mode/Bypass Mode) according to the operating status of the air conditioner

Pre-cool, Pre-heat Control

Reduces air conditioning load by not running the HRV while air is still clean soon after the air conditioner is turned ON.
