AHRE160 Decentralized Ventilation

AHRE160 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.

AHRE160 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.
