2022-04-28SMART Ventilation System with Zoning

SMART Ventilation System with Zoning


What is the SmartAIR system?

SmartAIR heat recovery system with zoning is the most intelligent, efficient system on the market. Why is it intelligent?

The ventilation system works independently, based on readings from sensors. Besides knowing how many people are in the house, the system also knows where they are.

Thus, it provides the right amount of air at the right time and place. A situation like this can be achieved by zoning, i.e. by dividing the house into day and night zones in accordance with the natural cycle of the day of the household members.

Here's how it might look:

  1. At night, we ventilate the night zone, e.g. bedrooms located on the 1st floor.
  2. In the daytime, we ventilate the day zone, which includes the living room and dining room.

Obviously, this is a simplified representation of how the algorithms may work. An intelligent HRV system requires sensors spread across multiple rooms to work (min. 2 sensors).

CO2, humidity, and motion detectors measure the air quality level (IAQ), as well as the presence of household members. Once they determine the air demand in a given zone, they send a signal.

As a result, the heat recovery system blows only as much air as is required by the residents, and not as much as the installer intended.

Would you like to live in a smart house? Choose the SmartAIR system

How about the most efficient system that uses as little energy as possible? Are you interested in smart technologies that minimize energy consumption? This mechanical ventilation system with zoning is the solution for you.

Ventilation designed for people, not buildings 

Control in the ventilation system with zoning is fully automatic. No resident interaction is necessary.

Installation needs to be adjusted only once. It will then regulate itself to meet the actual needs of the household. The sensor readings will be transmitted to the air handling unit in real-time, so the ventilation system operation will reflect actual needs.

Using that information, the heat recovery unit will deliver the right amount of fresh air at the right time and place.

As long as one of the zones is ventilated, the regulating T-piece sends a signal to the air handling unit to proportionally decrease the airflow, drastically reducing the electrical consumption. The reduced efficiency of the air handling unit reduces the power consumption as well as the energy used for heating.

Benefits of the SmartAIR system:

  • Saves energy - the heat recovery unit uses less electricity,
  • Enhanced comfort - the HRU is quieter,
  • High efficiency - a controlled level of fresh air, as required,
  • Less energy needed for heating,
  • ECO - the most energy-efficient way to control a heat recovery system,
  • SMART - the system designed to adapt to your needs,
  • You are always in control - monitor all parameters in the app.

2022-04-22EPP Manifold boxes for MVHR systems

EPP Manifold boxes for MVHR systems

Insulated manifolds at the price of uninsulated ones? 

The efficiency of the ventilation system with heat recovery does not end with the selection of an air handling unit. The air distribution system, including but not limited to ventilation ducts, plenum boxes and distribution boxes, is crucial for the proper operation of the heat recovery ventilation. 

And since the lack of insulation is one of the most common mistakes when installing an MVHR system. Therefore, in our offer, installers will find already insulated EPP plenum and distribution boxes that solve the problem of missing or incorrect insulation. 

EPP manifolds (distribution boxes)

Manifolds FLX-PLO-EPP-R are designed for use in domestic mechanical ventilation systems. They collect 75mm semi-rigid ducting, which is then distributed to the rooms. Typical installations contain from 1 to 2 such manifolds for the supply air and the extract air. Expanded polypropylene (EPP), the material used for the manifolds, is also an insulating material.

Why You should use EPP manifolds?

  • High thermal insulation: EPP is an insulating material with λ = 0.039 
  • Corrosion-resistant 
  • Simple and easy assembly - press-fit 
  • The plenum box body is made of EPP, the spigots are made of ABS
  • Excellent mechanical strength

Air duct humidifier for MVHR system


You want your home to have optimal air humidity, right? Get a HomeEvap duct humidifier!

An air duct humidifier allows you to regulate the relative humidity in your home. It can also solve the problem of dry air. HomeEvap air humidifiers are energy-efficient devices designed to be installed in mechanical ventilation systems with a maximum air volume of 600 m3/h.

Why should you buy a HomeEvap humidifier?

  • improves home comfort by regulating relative humidity,
  • the process of air humidification is natural - water evaporation,
  • suitable for direct installation in an HRV  system,
  • the automatic and energy-efficient operation,
  • easy to install and maintain,
  • EPP is used for the housing, and fibreglass for the matrix.
  • built-in PTC heater,
  • Legiosafe® water filter prevents bacteria growth
  • duct sensor (included) measures RH and prevents condensate from forming in ventilation ducts,
  • a wireless room controller and a duct sensor control the humidifier,
  • HRQ-HUM-HomEvap-200 set includes wireless controller, duct sensor, heater, legionella filter, matrix and valve.

How do duct humidifiers work?

A duct humidifier is installed in the supply duct behind the heat recovery unit, thus becoming part of the ventilation system. As soon as the relative air humidity falls below a certain level (we set the value ourselves), the humidifier kicks in.

Here is how the humidification process works:

  1. Humidity levels in our home are decreasing
  2. Dry warm air passes through the HomEvap humidifier
  3. Filtered water (Legiosafe®) naturally evaporates on a special matrix
  4. Then, the humidified air is distributed to the ventilation duct system and to connected rooms.
  5. The humidification process is regulated by a wireless room controller and a duct sensor.

Single room mvhr unit with WiFi - Energy efficient ventilation unit


Can a Single Room Heat Recovery Unit be controlled via WiFi? 

It can NOW! With the new HRU-WALL-WI model, You control the wall-mounted heat recovery unit via a free app.

 A single room heat recovery unit is a heat recovery ventilation system designed to effectively ventilate a single room (by supplying fresh air and removing used air while reducing condensation). Because these single room mvhr units are compact, they can be installed in an apartment or in an older building where the installation of a traditional ventilation system is impossible or too expensive.

The advantages of the HRU-WALL-WI heat recovery unit include:

  • Wi-Fi module allows you to connect the device to a local wireless network
  • With the WallAIR application, you can control:
    • Select a speed (3 speeds)
    • Select operation mode (alternating with recovery, unidirectional, temporary boost)
    • Wireless synchronization of several units
    • Temperature and relative humidity sensors readings
    • Grouping of heat recovery units, e.g. by rooms (wireless synchronization)
    • Automatic dehumidification mode
    • Statistical distribution of humidity over time
    • Filter replacement timer
  • Up to 82% heat recovery
  • 3 speeds
  • Airflow 20/40/60 m3/h
  • Easily installed and maintained
  • Ultra-quiet fan with a low sound power level of 38 dB (A)
  • Low power consumption (max 3.8W)
  • Integrated temperature and humidity sensors

Why You should choose NEWEST single room
 mvhr unit? 

We offer 3 variants of HRU-WALL heat recovery units. The main advantage of the HRU-WALL-WI wall-mounted mvhr unit is the integrated Wi-Fi module.

With the Wifi module, you can operate the device through a mobile application. The WallAIR app can also synchronize the work of multiple units:

  1. You can assign each unit to different groups,
  2. Switch modes simultaneously for all of them,
  3. Or you can control each unit separately.

This method of ventilation control allows the device to be customized to the needs of each household member. In other words, if one of your household members uses boost mode to ventilate their bedroom, then the rest of the apartment can be ventilated in daily mode 2 at the same time.

Synchronization is done using Wi-Fi, which minimizes heat recovery ventilation installation costs. In this case, You don’t need to connect the units via cables if we install several units.

2021-05-17PV system = 702 tons of CO2 less

PV system = 702 tons of CO2 less

Alnor Ventilation Systems reduces the carbon footprint! We just completed the installation of solar panels on our warehouse roof. 12,500 m2 of roof area was covered with 2,542 solar panels. The installed power of the PV system is 966kWp.

A photovoltaic system will generate an average of 865,000.0kWh (865MWh) of power annually to power our factory. This is roughly equivalent to the average annual electricity consumption of 360 households, while at the same time preventing 702 tons of carbon dioxide from entering the atmosphere per year.

What are the benefits of photovoltaics?

The use of solar energy is one of the most environmentally friendly methods of producing energy. As opposed to traditional energy sources such as coal, oil and natural gas, solar energy is renewable and "clean", which means it does not pollute the environment or release greenhouse gases.
