Apartment Buildings Solution

Ventilation with heat recovery has become an important topic for apartment building development as well. It is in fact quickly becoming the cornerstone of any low-energy development. WAFE smart solutions combines centralised and decentralised elements and its coherent with standards and fire regulations. Centralised ventilation preserves the architectural design, decentralised placement of units provides easy maintenance and individual responsibility. Among the key benefits of WAFE units are the possibility of universal positioning, user-friendly control, simple maintenance and no condensate drainage requirement. WAFE will provide you with a full service from project design and project management to installation and set up.

 

 

The optimal solution for developers

Any real-estate developer usually deals with the question, how to find a balance between the customer's requirement for simplicity and comfort and his own interests as an investor such as construction cost, reliability and space taken up by the technology itself. All these needs have been taken into consideration when it comes to WAFE 200 E unit. It is designed to ventilate each apartment individually, which means that each family can fully control the ventilation level without an effect on their neighbor's system. The slim shape of the unit allows for an intimate hidden ceiling installation that neither disturbs the silence nor the interior design. The best perk of all is the enthalpy heat exchanger that helps preserve the natural humidity, so important for any healthy environment.

 

Enthalpy heat exchanger

Common heat recovery units focus primarily on the transfer of heat from the waste air towards the fresh air. The first drawback of many units may be low efficiency that produces low temperature of the incoming fresh air causing lower comfort and the feeling of draft or the necessity for electricity demanding air heater. Units with high efficiency on the other hand suffer from frost of condensate inside the exchanger and require the use of an electric preheater for outside temperatures below zero. One way or the other, most of the common heat recovery units neglect one of the most important quality parameters of the air - the relative humidity. During the heat exchange in any counter-flow exchanger, condensation occurs taking the humidity of the interior down the drain. This leads to excessive drying of the interior air. The enthalpy exchanger technology of WAFE 200 E eliminates these risks. The heat as well as the natural humidity is recovered through the fine membrane of the exchanger while unwanted odors, CO2, volatile substances and other pollutants are ventilated out of the building.

 

Smart combination of the centralised and decentralised ventilation system

  • The unit is placed in the apartment – the primary responsibility lies with the owner or the tenant

  • Simple maintenance – filter exchange only

  • Thanks to centralised air intake and air discharge there is no need of neither facade nor fire dampers. That prolongs local filters’ lifetime.

  • This solution is coherent with the standard for fire safety and hygiene. Also it does not influence the design and static properties.

  • Thanks to unit's parameters and the parameters of the air distribution system, there is no need for other components for noise or dust reduction in the building.

Main benefits for the resident

  • No matter the weather, smog or noise, there is still fresh air in your apartment.

  • Better sleep thanks to reduced outside noise and fresh air even with the windows closed.

  • Optimal relative humidity reducing various health risks.

  • Apartments retain higher value as heat recovery ventilation becomes the market standard.

  • Heat recovery ventilation can be part of the “smart home” concept.
