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.

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 unit, 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 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
Air handling unit control panel 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 
outside air), makes it possible to turn on the unit in the FRESH UP mode, when the air supply exceeds its exhaust by 20%, which is very important for normal operation exhaust ventilation in the kitchen, c / a and bathroom. Using the control panel, you can set a timer and adjust the volume of air supplied to the room. The display shows information about the operating mode of the unit, set timers, replacement of dust filters and the need to clean the heat exchange cassette.
The factory fan speed settings can be changed using the service settings. Using the service menu, you can select the maximum and minimum fan speeds out of 14 possible.

Unit dimensions
The HRV system helps create a comfortable environment by interacting with the air conditioning system. The HRV (Heat Recovery Ventilation) system returns thermal energy lost during ventilation and smooths out 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, automatically switches to ventilation mode, which increases the energy saving level. The operation of the HRV system is centrally controlled from the console remote control conditioner. This provides simple overall control of air conditioning and ventilation.
These configurations include models with a DX heat exchanger and/or - a DX heat exchanger helps protect personnel from direct action cold air flow during the heating cycle and vice versa. The high static pressure increases the design flexibility of the system.
1. ENERGY EFFICIENCY
More than 30% block size reduction
The use of a high quality paper (HEP) element and optimized design of the fan and airflow channels resulted in a very compact unit while maintaining the 28% reduction in A/C 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% by pre-cooling and heating control (reduces the load on the air conditioning system without an operating HRV system, when the air remains clean for a certain time after switching on.)
Note: The above values are subject to change depending on the weather and other conditions. environment at the location of the unit

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 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 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: 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 a very good solution 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 noise level. 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, which can be selected by the remote controller of the unit or the remote controller 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; auto 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 changeover of 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 VRV II.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 with high demands to energy efficiency. When developing equipment, the thermophysical properties of heat exchange surfaces, the efficiency of electric motors, the degree of filtration, insulation, reduction of friction and pressure drops of the air flow are taken into account. 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.
