Independent operation possible

Operable outdoor temperature down to –15°C

Quiet operation

Independent operation of HRV (VKM) type indoor unit is possible (on/off control only) by connecting an optional remote controller.

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.

Reduced pressure loss and quieter operation internally lowers the noise output of the VKM50GMV1 system to 35/36 dB (220–240 V, 50 Hz).

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.

Utilizing the principle of capillary action, water is permeated throughout the humidifier element. The heated air from the DX-coil goes through the humidifier and absorbs the moisture.

Night Purge Operation

Automatic changeover to efficient operation patterns

Energy savingEfficient outdoor air introduction with heat exchangerand cooling/heating 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.

Operation automatically changes to the optimum pattern to suit conditions.

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.

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.

OFF Dust

W i t h C o m p e t i t o r s ' P r o d u c t sWhen conventional total heat exchange units, which are independently operated using a dedicated remote controller, are directly connected by a duct, there is a possibility of dust falling from the air filter of the indoor unit when the air conditioner is OFF.

W ith the H R V (V K M )When the HRV (VKM) is operating independently, the fan in an interlocked indoor unit continues turning, so dust does not fall from the air filter.

Blowing mode No dust is blown out.

S upply F re s h-up: Raising the air supply maintains proper room pressure to prevent back-flow of toilet/kitchen odors or moisture inflow.

E x ha us t F re s h-up: Raising exhaust air decreases room pressure to prevent the leaking of odors or floating bacteria into other rooms.

Note: 1. Cooling and heating capacities are based on the following conditions. Fan is based on High and Ultra-high.The figures in the parenthesis indicate the heat reclaimed from the heat recovery ventilator.When calculating the capacity as indoor units, use the following figures:VKM50GMV1/GV1: 3.5 kW, VKM80GMV1/GV1: 5.6 kW, VKM100GMV1/GV1: 7.0 kW

2. Indoor temperature: 27°C DB, 19°C WB, Outdoor temperature: 35°C DB3. Indoor temperature: 20°C DB, Outdoor temperature: 7°C DB, 6°C WB4. Humidifying capacity is based on the following conditions:

Indoor temperature: 20°C DB, 15°C WB, Outdoor temperature: 7°C DB, 6°C WB5. The operating sound measured at the point 1.5 m below the center of the unit is

converted to that measured in an anechoic chambar built in accordance with the JIS C 1502 conditions. The actual operating sound varies depending on the surrounding conditions (near running unit’s sound, reflected sound and so on) and is normally higher than this value.For operation in a quiet room, it is required to take measures to lower the sound. For details, refer to the Engineering data.

6. The noise level at the air discharge port is about 8–11 dB or higher than the unit’s operating sound.For operation in a quiet room, it is required to take measures to lower the sound.

7. Air flow rate can be changed over to Low mode or High mode.8. In case of holding full water in humidifier.9. OA: fresh air from outdoor. RA: return air from room.

10. Specifications, design and information here are subject to change without notice.11. Power consumption and efficiency depend on the above value of air flow rate. 12. Temperature exchange efficiency is the mean value for Cooling and Heating.

Efficiency is measured under the following condition: Ratio of rated external static pressure outdoor to indoor is kept constant at 7 to 1.

Feed clean water (city water, tap water or equivalent). Dirty water may clog the valve or cause dirt deposits in the water container, resulting in poor humidifier performance. (Never use any cooling tower water and heating-purpose water.)Also, if the supply water is hard water, use a water softener because of short life.* Life of humidifying element is about 3 years (4,000 hours) under the supply water

conditions of hardness: 150 mg/l. (Life of humidifying element is about 1 year (1,500 hours) under the supply water conditions of hardness: 400 mg/l.)Annual operating hours: 10 hours/day x 26 days/month x 5 months = 1,300 hours

• 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)

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.

Group ControlOne air conditioner remote controller simultaneously controls up to 16 air conditioner and HRV (VKM) units.*1: Count HRV (VKM) unit as two air conditioners. For details, see Table 1 on page 13.

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.

Examine fully the installation place and specification for using the electric heater based on the standard and regulation of each country.Supply the electric heater and safety production devices such as a relay and a thermostat, etc., of which qualities satisfy the standerd and regulation of each country at site.Use a non-inflammable connecting duct to the electric heater. Be sure to allow 2 m or more between the electric heater and HRV (VKM) for safety.For the HRV (VKM) units, use a different power supply from that of the electric heater and install a circuit breaker for each.
