AHR160 Decentralized Ventilation
.png)
AHR160 is a new generation of decentralized ventilation devices facilitating ventilation while reducing heat loss. Thanks to the use of an accumulation heat exchanger, the AHR retains and stores heat energy to transfer it to the cooler, supplied air. The difference between the AHR and HRV series lies in the solutions used to automate its operation. The applied electronics control the operation of the device and adjusts its parameters depending on the conditions in the room where the AHR is installed.
AHR160 has the ability to connect several devices installed in one or more rooms with the possibility of pairing them via wireless communication. No hassle of connecting devices with a power cord. Connection possible in various modes, e.g. both units only supply or only exhaust and alternate operation, one unit blows in and the other blows out.
Principle of operation
The main function of the AHR160 device is to ensure air exchange in the room while reducing heat loss. The recovery of heat lost in the ventilation process is possible thanks to the use of a ceramic accumulation exchanger, which retains and accumulates thermal energy and then warms the cooler air supplied from the outside. If the supplied air has a higher temperature than that in the room, the exchanger will lower it using the temperature of extracted air.
Exhaust
During exhaust operation, the heat is stored in a ceramic heat exchanger. After the exchanger is completely warmed up, it automatically changes the direction of operation.
The optimal one-way operation time is determined by the temperature readings from sensors located upstream and downstream of the heat exchanger.
Airflow
The heat accumulated in the exchanger is collected by the supply air stream and then transferred to the room. After the exchanger cools down, it automatically changes the direction of operation.
The optimal one-way operation time is determined by the temperature readings from sensors located upstream and downstream of the heat exchanger.
Communication
Wireless communication
AHR160 has the ability to connect several devices installed in one or more rooms with the possibility of pairing them via wireless comunication. No hassle of connecting devices with a power cord. Connection possible in various modes, e.g. both units only supply or only exhaust and alternate operation, one unit blows in and the other blows out.
Arrangement example
AHR160 has been designed so that it is possible to create a network of devices operating simultaneously in many rooms in one house. The more of them are installed, the more fresh air is supplied to the interior. The lower heating costs during the heating seasons is the additional value of having AHR installed.
Display
The LED display located on the bottom of the fan provides to the users the important information about the device itself and surrounding conditions, such as humidity level, air temperature, fan speed (gear), air flow direction, time remaining until the device is turned off (if TIMER has been set) and also the current time.
All five display modes are presented in the above graphic.
Device components
The ceramic exchanger
The ceramic exchanger is the heart of the device and one of its most important elements. In AHR, a hexagonal exchanger was used, thanks to which one of the highest heat recovery rates in decentralized ventilation devices available on the market was obtained.
Motor
AHR is equipped with 24V DC Energy-saving brushless motor.
Duct
Duct was made of PVC with addition of silver ions to prevent proliferating of bacteria inside of it. Additional insulation was used to reduce condensation and heat loss.
Remote control
The AHR160 is equipped with an infrared remote control, enabling the device to be operated in the full range of changing operating modes, operating speed as well as switching on and off.
More information in section ‘EQUIPMENT’.
Filtres
The AHR is equipped with two air purifying filters.
Temperature and humidity sensor
The wireless temperature and humidity sensor enables automatic operation of the device, which, based on the measurements, adjusts the operating speed.
Automatic shutters
Automatic shutters that cut off the air flow when the device is turned off and a soundproofed internal panel increase the comfort of use.
Equipment
Terminal block
The fan is switched on and off by means of a switch (not included in the device) being a part of the building’s electrical system.
Humidity sensor AHR
AHR160 is standardly equipped with a humidity sensor (HIGRO mode), thanks to which, the device is turned on when the humidity level in the room where it is installed exceeds the set value. This value can be set by the user in the range from 10% to 90% in 10% increments. In the HIGRO mode, the device compares the measured value of room humidity with the value set by the user. If the measured value is greater than the set value by 0-10%, the device will turn on in the first gear, by 10-20% - in the second, more than 20% - in the third gear. The device will be turned off when the actual humidity level is equal to the set one.
Activation of the HIGRO mode is signaled by the flashing symbol on the device screen.
Function operated by remote control.
Timer AHR
The device has the ability to automatically turn off after 5, 10, 15, 30, 45, 60, 120 and 180 minutes from turning on. The display shows the time remaining until shutdown. Shifting the gear does not affect the clock operating. After the set time has been counted down, the device will turn off and the last used gear will be remembered.
Activation of the mode is signaled by the sequential lighting of the LEDs (from top to bottom) in the central part of the display.
Function operated by remote control.
Three-speed
The three speed option is available in the AHR decentralized fan model, only. The gears are switched up/down with a remote control or automatically - the operating parameters of the device are adjusted to the prevailing conditions thanks to the temperature and humidity sensor.
Remote control AHR
The remote control for AHR160 allows the device to work in the following modes:
* RECUPERATION (The flow direction is changed automatically based on the measurement temperature)
* TIMER (enables automatic shutdown of the device after 5-180 minutes)
* HUMIDITY (the speed depends on the settings and currently measured humidity)
* EXHAUST (continuous operation in the exhaust direction)
* AIRFLOW (continuous operation in the airflow direction)
* NIGHT (silent)
In addition, the remote control allows you to synchronize an infinite number of AHR devices, set the clock time and reset the filter contamination counter.
