Heat Reclaim Ventilation VKM-G(M) series
The new HRV lineup features the DX-coil in response to recently diversifying outdoor air introduction requirements.
Efficient outdoor air introduction and temperature adjustment to suit conditions indoors. This is realized by heat exchanger and energy saving technology unique to Daikin. The lineup now includes models with a humidifier, responding to diversifying customer requirements. The features you expect from Daikin are there. The DX-coil contributes to the prevention of cold airflow hitting people directly during heating operation. High static pressure enhances design flexibility. All these cutting-edge technologies are packed in an integrated compact body. Daikin, the top provider of high quality indoor air, offers even more comfortable environment.
Humidifier
The lineup now includes models with a humidifier, in respone to diversifying customer requirements.
DX-coil
The HRV features DX-coil that contributes to the prevention of cold airflow hitting people directly during heating operation, due to the after-cool, after-heat operations done beforehand.
High static pressure
Higher external static pressure means enhanced design flexibility.
A compact unit packed with Daikin’s cutting-edge technologies
Proprietary Developed HEP Element
The heat exchange element uses a High Efficiency Paper (HEP) that has superior moisture-absorption and humidifying properties and doubles the current efficiency of moisture absorption.
The heat exchange unit speedily recovers heat contained as latent heat (vapor). The element is made of a material with superior flame-resistant properties and is treated with an anti-molding agent
Design flexibility
Efficient fan performance produces a high static pressure
Improvements to the fan, including the use of multi-arc blades, a thinner scroll and optimized fan scroll angle, help to boost efficiency.
Dramatically higher static pressure is achieved due to improved fan performance. This reduces limitations on unit placement and allows more flexibility in duct design.
Unique control system
Independent operation possible
Independent operation of HRV (VKM) type indoor unit is possible (on/off control only) by connecting an optional remote controller.
Design flexibility
Operable outdoor temperature down to –15°C
If the outdoor air suction temperature falls below –10°C, the unit changes to intermittent operation to prevent freezing of the heat exchanger element and dew condensation within the unit.
Intermittent operation
A thermistor (standard equipment) within the unit detects the outdoor air temperature. Unit operation varies according to the detected temperature.
Quiet operation
Reduced pressure loss and quieter operation internally lowers the noise output of the VKM50GMV1 system to 35/36 dB (220–240 V, 50 Hz).
Design flexibility
Indoor unit connectable to up to 130% of the capacity of the outdoor units
Energy saving
Night Purge Operation
Night purge is an energy-conserving function that works at night when air conditioners are off. By ventilating rooms containing office equipment that raises the room temperature, night purge reduces the cooling load when air conditioners are turned on in the morning.
- Night purge only works to cool and if connected to Building Multi or VRV systems.
- Night purge is set to “off” in the factory settings, so if you wish to use it, request your dealer to turn it on.
Energy saving
Automatic changeover to efficient operation patterns
Operation automatically changes to the optimum pattern to suit conditions.
Energy saving
Efficient outdoor air introduction with 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.
Easy installation + Space saving
Integrated system includes ventilation and humidifying operations
Rather than using separate ventilation and humidifying components, the system incorporating HRV (VKM) integrates all functions, reducing the total number of indoor units and facilitating a far simpler system. The installation space becomes smaller and the labor required for installation and maintenance is reduced significantly.
Easy operation
Ventilation, cooling/heating and humidifying are possible with one remote controller.
Various air conditioner functions can be managed using a single remote control. This makes it easy to obtain high-quality and energy-efficient outdoor air treatment.
Design flexibility
Slim design
The slim design of only 387 mm in height enables installation inside ceilings with less than 407 mm of clearance.
Clean
- Fresh-up Operation
The user can select between two fresh-up modes using the remote controller.
- Preventing Dust from Falling with Directly Mounted Ducts
- A sign is displayed on the remote controller when the air filter needs cleaning.
Model Line Up
Centralized Control of Air Conditioning and Ventilation
Operation of the air conditioner using the remote controller is interlocked with operation of the HRV, greatly simplifying overall system control. The same remote controller completely centralizes air conditioning and ventilation operations, so no HRV remote controller installation work is necessary. Using a centralized remote controller also frees the user to choose from a wide range of control systems that integrate air conditioning and ventilation. By incorporating a variety of centralized control equipment, the user can build a large, high-grade centralized control system.
Operations and Control with the Air Conditioning Remote Controlle
- Simultaneous ON/OFF of the HRV (VKM) and air conditioner
- Independent operation of the HRV (VKM)
- Airflow rate switching (initial setting)
- Ventilation mode switching (initial setting)
- Self-diagnosis functions
- Filter sign display and reset
- Timer settings (simultaneous control with air conditioner)
- Fresh-up mode switching (Selectable: supply rich mode, exhaust
- rich mode; Initial setting)
A Variety of Contr ol Systems That Can Be Controlled Using Only the Air Conditioner Remote Controller
Centralized Control System
By combining the (optional) centralized control equipment below, the user can achieve a wide range of comprehensive centralized control systems for air conditioning and ventilation.
HRV (VKM) Control Systems
Various Control Systems According to Applications and Conditions
Option
Installation of Optional Pr oducts (For VKM50G (M) V1, VKM80G (M) V1, VKM100G (M)
- PC board adaptor for heater control kit (BRP4A50)
When the installation of an electric heater is required in a cold region, this adaptor with an internal timer function eliminates the complicated timer connecting work that was necessary with conventional heaters.
