The HRV system helps create a comfortable environment by interacting with the air conditioning system. Daikin's HRV (Heat Recovery Ventilation) system recovers thermal energy lost during ventilation and smoothes the change in room temperature caused by ventilation, thereby maintaining a comfortable, clean environment. It also reduces the load on the air conditioning system and saves energy.
In addition, the HRV system works in conjunction with the VRV® system, Sky Air and other systems Daikin air conditioning, automatically switches to ventilation mode, which increases energy saving. The HRV system is controlled centrally from the remote control remote control air conditioner This provides easy general management air conditioning and ventilation.
Current configurations include models with a DX heat exchanger and/or humidifier - the DX heat exchanger helps protect personnel from direct exposure to cold airflow during the heating cycle, and vice versa. High static pressure increases system design flexibility.
1. ENERGY EFFICIENCY
Reduce block size by more than 30%
The use of high quality paper (HEP) element and the optimal design of the fan and airflow channels result in a very compact unit, while maintaining the 28% reduction in air conditioning load achieved by previous models. The height of the main unit has been reduced by 40mm, allowing it to be easily installed in areas where space is limited, e.g. suspended ceilings.
Reducing the load on the air conditioning system by an average of 28% (maximum 40%) includes:
- 20% due to operation in full heat exchange mode (compared to conventional fans)
- 6% due to automatic switching of ventilation mode
- another 2% by regulating pre-cooling and heating (reduces the load on the air conditioning system without the HRV system running, when the air remains clean certain time after switching on air conditioner.)
Note: Above values may vary depending on weather and other conditions environment at the location where the unit is installed
Brand element made from high quality paper (HEP)
The heat exchanger element is made of high-quality paper (HEP), which has excellent moisture-absorbing and humidifying properties. This allows the heat exchanger to quickly recover the heat contained in the latent heat (steam). The element is made of fire-resistant material treated with an agent to prevent deformation.
Heat exchanger element operation
Automatic switching to efficient work patterns
During operation, automatic switching occurs optimal scheme according to current prevailing conditions
2. DESIGN FLEXIBILITY
Operation at outside temperatures down to -15°C
If the outside suction air temperature drops below -10°C, the unit goes into intermittent operation, which prevents the heat exchanger element from freezing and condensation forming in the unit.
Intermittent Operation = A thermistor (standard equipment) in the unit senses the outside air temperature. The operation of the unit changes according to a certain temperature.
Compact dimensions
The compact dimensions of the HRV unit allow it to be easily installed in narrow space between the suspended ceiling and the ceiling, as well as in irregularly shaped spaces.
Compact design
The unit can be mounted horizontally or upside down, depending on the specific installation location. The 450 mm square inspection hatch makes it easy to carry out maintenance and replacement heat exchanger element.
Quiet operation
Levels sound pressure are very low and equal to 20.5 dBA (VAM150FA)
3. CLEAN AIR
Innings fresh air
The user can select 2 fresh air modes using the remote control.
Preventing dust from settling
Prevents dust from settling thanks to direct installation of air ducts.
Cleaning the filter
The remote control signal indicates when the air filter requires cleaning.
VKM SYSTEM CHARACTERISTICS
1. ENERGY EFFICIENCY
Natural cooling at night allows you to save energy at night when the air conditioning system is turned off. By ventilating rooms containing office equipment, which raises the room temperature, night mode reduces the cooling load when the air conditioning system is turned on in the morning.
Nighttime free cooling only works when connected to multi-unit or VRV® systems.
Night free cooling is factory set to “off” but can be enabled by your Daikin dealer at your request.
Efficient preparation of outside air via heat exchanger and cooling/heating switching mode
Indoor unit with outdoor air preparation.
With the help of outside air, the temperature can be brought to a temperature close to the indoor air temperature, with minimal cooling power.
2. DESIGN FLEXIBILITY
High static pressure
Modifications to the fan design, including the use of multi-arc blades, a thinner volute and optimal angle Fan spirals provide increased operating efficiency. Significantly higher static pressure is achieved due to improved fan characteristics. This allows you to reduce restrictions on block placement and provides flexible design air duct.
Connectivity of indoor units
Connectable indoor units can account for up to 130% of the power of the outdoor unit

Additional options and accessories
DAIKIN VAM series heat exchangers are not equipped with frost protection. When operating ventilation units below -10 0 C, it is desirable to install frost protection, which includes:
1. Air heater.
2. Thermostat.
3. Relay.
4. Differential pressure sensor
Installation of an additional air heater is necessary when the structure operates at temperatures below -10 degrees. Its power is initially calculated for maximum air flow. If, as the outside temperature decreases, the air flow decreases, the formula is used to calculate the heater power:
N= -0.33x(T+15)xL
Where: N- heater power, calculated in kW,
T-minimum design temperature for a specific region,
L- air flow in m3/hour.
The heater must be controlled by a capillary thermostat (Shuft NET-5/HY) with an operating temperature range from -30 0 C to +30 0 C, through a solid-state relay or magnetic starter.

| Price: 4200 rub. | Price: from 1250 rub. | Price: 2100 rub. | Price: from 2500 rub. |
A magnetic starter, unlike a relay, although it has a lower cost, also has a number of disadvantages, one of which is contact noise when turning the load on and off. To avoid extraneous noise during operation of the installation heater, it is advisable to install a solid-state relay that is completely silent in operation. Just like heaters, relays are selected depending on power.
If the recuperator is planned to be installed in a warm room, then it is advisable to additionally install air dampers at the air inlet and outlet from the unit to the street, which will open when the unit is turned on and closed when it is turned off.
In order to be able to connect electrically driven air dampers to the installation, it is necessary to use a differential pressure sensor, the sensors of which are installed before and after the supply fan. A pressure sensor is also required when a frost protection kit is connected to the installation. As a result of the fan triggering when the unit is turned on, a pressure difference is created and the sensor sends a signal to open the air dampers and to the frost protection device.
PS500B Operating Instructions Control panel for air handling unit DAIKIN
Air handling unit control panel BRC301B61 allows you to remotely control it, switch operating modes with or without a recuperator (relevant in the summer, when the air temperature drops at night and you can cool the room at 
using street air), makes it possible to turn on the unit in FRESH UP mode, when the air inflow exceeds its exhaust by 20%, which is very important for normal operation exhaust ventilation in the kitchen, bathroom and bathroom. Using the control panel, you can set a timer and regulate the volume of air supplied to the room. The display shows information about the operating mode of the unit, set timers, replacing dust filters and the need to clean the heat exchange cassette.
Factory fan speed settings can be changed using service settings. Using the service menu, you can select the maximum and minimum fan speeds from 14 possible.

Installation dimensions
Daikin VAM-FB— supply and exhaust ventilation unit with heat recovery series HRV, which can be used as part of a multi-zone air conditioning system VRV Daikin. Great option for an apartment country house or office. Supply and exhaust ventilation units HRV corporations DAIKIN allow you to create ventilation systems with simple and convenient controls, with heat transfer efficiency of up to 80%. The heat exchange unit included in the installation reduces energy losses to a minimum winter period year, transferring the heat of the exhaust air to the cold (supply) air flow.
The Daikin VAM1000F/FA/FB air handling unit with heat recovery VKM performs not only temperature exchange between air flows, but also humidity, and thereby “stabilizes” the air in the room. The ability to humidify the air is in many cases a decisive factor when choosing Daikin units.
At the same time, it is possible to avoid excessive dryness of the air in the room, since the special material of the heat exchange block leaves not only heat in the room, but also up to 60% moisture. During the summer period, installation HRV reduces the thermal load on the air conditioning system by an average of 20%. This makes it possible to use air conditioners with lower cooling capacity for the same rooms.
Unified control of air conditioning and ventilation will save a few more percent. Additional energy savings can be achieved by using the “Pre-cool/heat” mode. According to this mode, the ventilation system starts with a delay relative to the operation of the air conditioner, which reduces the time required to cool/heat the room.
Distinctive features: The compact and energy-saving HRV ventilation system has a wide range of models (9 models with air flow from 150 to 2000 m3/h). This is very good decision for ventilation of apartments and offices.The permissible outside air temperature range is from -15 °C to +50 °C. The scope of application has been expanded with the possibility of saving energy.
Low noise level. The new Multi Arc Blade Fan provides a noise level of 27 dBA (for VAM150FA), which allows the ventilation unit to be installed even in sleeping areas
More efficient and compact heat exchanger. The transfer rate of latent heat and water vapor has been increased, which has made it possible to reduce the dimensions of the heat exchanger by 25% compared to the previous model.
Fresh Up mode prevents entry into the room unpleasant odors from the toilet and cold air.
Air conditioning and ventilation can work together, which increases efficiency climate system and allows you to control: joint start-up or shutdown; the ability to control ventilation independently of the air conditioner; changing the ventilation mode (auto/heat exchange mode/no heat exchange); indication of filter contamination; changing the air flow speed (high/low); activating the air pre-treatment function before starting the air conditioner.
Ventilation unit Daikin HRV has three ventilation modes that can be selected using the unit's remote control or remote control indoor unit VRV: full heat exchange mode, when supply and exhaust air exchange heat and moisture; bypass mode, when supply air is directly supplied to the premises, bypassing the heat exchange unit; automatic mode, when the room temperature is automatically selected optimal mode work.
Using high quality paper item ( HEP) and the optimal design of the fan and airflow channels result in a very compact unit, while maintaining the 28% reduction in air conditioning load achieved by previous models.
The height of the main unit is reduced by 40mm, allowing it to be easily installed in areas where space is limited, such as suspended ceilings. Reducing the load on the air conditioning system by an average of 28% (maximum 40%) includes: 20% due to operation in full heat exchange mode (compared to conventional fans) 6% due to automatic switching of the ventilation mode another 2% due to pre-cooling control and heating (reduces the load on the air conditioning system without the system running HRV, when the air remains clean for a certain time after turning on the air conditioner.)
Two speeds can be selected using the unit's remote control HRV or indoor unit remote control VRV. Selecting a ventilation mode From the remote control, you can set a ventilation mode in which the supply of supply air exceeds the flow of exhaust air and eliminates the possibility of unpleasant odors from the kitchen or toilet entering the room. By changing the remote control settings, you can set the ventilation mode so that the exhaust air flow rate is greater than the supply air flow. In addition to remote control HRV or indoor unit VRV, installation HRV easily integrated into a centralized management system VRV II.There are pre-cooling or pre-heating modes, according to which the ventilation is turned on with a certain delay relative to the moment the air conditioner starts. This significantly increases system efficiency and reduces energy consumption.
