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 control, with a heat exchange efficiency of up to 80%. The heat exchange unit included in the unit minimizes energy losses in the winter period of the year, transferring the heat of the exhaust air to the cold (supply) air flow.
The Daikin VAM1000F/FA/FB air handling unit with VKM heat recovery performs not only temperature exchange between air flows, but also humidity exchange, and thus “stabilizes” the air in the room. The possibility of air humidification 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 unit leaves the room not only warm, but also up to 60% moisture. During the summer season, the installation HRV reduces by an average of 20% heat load to the air conditioning system. This makes it possible to use air conditioners with a lower cooling capacity for the same rooms.
A single control of air conditioning and ventilation will save a few more percent. Additional energy savings can be achieved by using the "Precool/Heat" mode. Under this mode, the start of the ventilation system is delayed in relation to the operation of the air conditioner, which reduces the time required for cooling / heating the room.
Distinctive features: The compact and energy-saving HRV ventilation system has a wide the lineup(9 models with air flow from 150 to 2000 m3/h). This is very good decision for ventilation of apartments and offices.Permissible outdoor air temperature range from -15 °С to +50 °С. Expanded scope with the possibility of saving energy.
Low level noise. The new Multi Arc Blade Fan provides a noise level of 27 dBA (for VAM150FA), which allows you to install a ventilation unit even in bedrooms
More efficient and compact heat exchanger. The rate of latent heat and water vapor transfer 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 eliminates entry into the room unpleasant odors from the toilet and cold air.
Joint operation of the air conditioner and ventilation is possible, which increases the efficiency of the climate system and allows you to control: joint start-up or shutdown; the possibility of ventilation control independent of the air conditioner; changing the ventilation mode (auto/heat exchange mode/no heat exchange); indication of filter contamination; change in air flow rate (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 remote control remote control installation or remote control of the indoor unit VRV: full heat exchange mode, when the 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 a bond paper element ( HEP) and optimized design of the fan and airflow ducts resulted 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, making it easy to install in space-constrained areas such as false 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 a running system HRV when the air remains clean for a certain time after the air conditioner is turned on.)
Two speeds can be selected using the installation remote control HRV or indoor unit remote control VRV. Selecting the ventilation mode The remote control can be used to set the ventilation mode, in which the supply air supply exceeds the exhaust air flow rate and excludes 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 extract air flow is greater than the supply air. In addition to remote control HRV or indoor unit VRV, installation HRV easily integrated into the centralized control system VRVII.Pre-cooling or pre-heating modes are provided, according to which ventilation is switched on with a certain delay in relation to the moment the air conditioner is started. This significantly improves system efficiency and reduces power consumption.

energy efficiency
All installations are designed to meet high energy efficiency requirements. When developing equipment, the thermophysical properties of heat exchange surfaces are taken into account, the coefficient useful action motors, degree of filtration, insulation, reduction of friction and pressure drops of the air flow. The energy efficiency of installations can be further increased by heat recovery.
Efficient air treatment
Depending on the requirements for air purity, central air conditioners are equipped with filters of various degrees of efficiency:
- synthetic corrugated
- flat in aluminum steel mesh
- compact and soft bag
- absorption
- deodorizing
All filters are mounted on commercially available frames with seals.
To prevent dust from entering the air passage when performing Maintenance, the filters are removed from the contaminated side.
The units can be equipped different types and models of humidifiers. Options are available with fully removable humidifiers or with a removable surface evaporation humidifier section.
The units may include heat exchangers with an intermediate coolant or freon, electric heaters, fans, heat recuperators, gas-burners, silencers, controls, automation and security.
D‑AHU units can be combined with chillers and large condensing units, including Daikin inverter condensing units with ozone friendly R‑410A refrigerant.
Variety of designs
The overall dimensions of the central air conditioner can be selected depending on the actual installation conditions. The design is based on a supporting frame and profiles made of aluminum (or anodized aluminum, which is best suited for working in aggressive environments) with a section of 40x40 or 60x60 mm. There are modifications of profiles with a section of 60x60 mm with a thermal insulating insert to reduce heat loss. Profiles with oval inner surface recommended for use in the food industry, medicine, and other areas with special hygiene requirements.
Panels can be flat, 25 and 46 mm thick, or stepped, 42 and 62 mm thick.
Stepped panels allow you to get flat surface inside the product. Insulation is made of polyurethane foam (40-50 kg/m3) or fibrous mineral wool(90 kg/m3).
Daikin central air conditioners use components produced by companies that are world leaders in their fields: Daikin, Siemens, Belimo, Nicontra, Comefri, Gebhardt.
Modern management
The units are completed with a control cabinet based on a digital controller with all power and control connections. Upon request, the units can be supplied with sensors, servo drives and protective devices.

Additional options and accessories
DAIKIN VAM series recuperators 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 is operating at temperatures below -10 degrees. Its power is initially calculated for the maximum air flow. If the air flow decreases with a decrease in the temperature outside, the following 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 particular region,
L- air consumption in m3/h.
The heater must be controlled by a capillary thermostat (Shuft NET-5/HY) with an operating temperature range of -30 0 С to +30 0 С, via a solid state relay or a magnetic starter.
| Thermostat | Solid state relay | Differential pressure transmitter PS500B | Duct heater | |
 |  |  |  |
|
| Price: 4200 rub | Price: from 1250 rubles. | Price: 2100 rubles. | Price: from 2500 rubles. |
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 the load is turned on and off. To avoid extraneous noise during the operation of the plant heater, it is desirable to install a solid state relay that is completely silent in operation. Just like heaters, relays are selected depending on the power.
If the heat exchanger is planned to be installed in a warm room, then it is advisable to additionally install air dampers at the air inlet and outlet of the unit to the street, which will open when the unit is turned on and close when it is turned off.
In order to be able to connect motorized air dampers to the installation, it is necessary to use a differential pressure sensor, the sensors of which are installed before and after supply fan. A pressure sensor is also required when a frost protection kit is connected to the system. As a result of the operation of the fan when the unit is switched 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
DAIKIN air handling unit control panel
Remote Control air handling unit BRC301B61 allows you to remotely control it, switch operating modes with or without a heat exchanger (relevant in the summer, when the air temperature drops at night and you can cool the room when
