Function of the ventilation system with heat recovery

A ventilation system with heat recovery ensures optimal air exchange in houses and apartments. It transports old, used and pollutant-rich air from the rooms and exchanges it for fresh, oxygen-rich air from outside. Heat recovery makes it possible to transfer a large part of the heat from the old air to the fresh outside air without incurring additional heating costs. The heat recovery rate indicates how efficiently the heat recovery works and how much of the heat can be transferred to the fresh air.

In addition to heat, some ventilation devices can also recover moisture and thus ensure a healthy indoor climate. Controlled ventilation with a ventilation system with heat recovery ensures high air quality as used air is removed and fresh air is supplied. This ensures a pleasant and healthy indoor climate in living and working spaces.

Controlled ventilation system and air supply

A ventilation system with heat recovery is one controlled ventilation system, because the air exchange is controlled specifically. Ventilation takes place through a Ventilation unit, which is equipped with special filters to remove particles and pollutants from the air. The filtered outside air is led into the rooms via a pipe system, while the used air is exhausted outside via a separate pipe system.

The ventilation system with heat recovery ensures constant, sufficient and well-controlled air supply in the rooms. The use of heat recovery systems also saves energy, as the existing heat from the extracted air is transferred to the fresh supply air.

The ventilation system with heat recovery not only ensures optimal air quality, but also efficient use of the available energy.

Advantages of a ventilation system with heat recovery Disadvantages of a ventilation system with heat recovery
– High air quality – Initially high acquisition costs
– Energy saving through heat recovery - Regular Maintenance necessary
– Healthy indoor climate – Space required for ventilation devices
– Controlled air supply – Installation during renovations is often complex

Types of ventilation heat recovery

Depending on the structure and function of the ventilation technology, there are different technologies for heat recovery. A common type is this recuperative heat exchangers, in which the cold outside air flows directly past the warm exhaust air, with partition walls preventing the air flows from mixing. This allows the heat from the old air to be transferred to the fresh outside air without transferring odors, particles or moisture. An example of this type of heat recovery is the plate heat exchanger, which is used in many devices for controlled living space ventilation.

Another approach to heat recovery is this regenerative heat exchangers. Here, two air streams are passed through a storage element that absorbs the heat energy from the old air and later releases it into the fresh outside air. This method can achieve higher efficiency because the thermal energy is stored and transferred directly.

Another innovative technology is the Air heat exchanger with heat pump. The thermal energy from the exhaust air is used to heat the cold outside air. A heat pump further strengthens this process so that even more heat energy can be recovered. This type of heat recovery is particularly suitable for use in energy-efficient buildings.

Type of heat recovery Benefits Example
Recuperative heat exchanger – Transfer of heat energy without mixing odors and particles
– High efficiency in heat recovery
Plate heat exchanger
Regenerative heat exchanger – Direct storage and transmission of thermal energy
– High efficiency in heat recovery
-

Central or decentralized ventilation

When choosing a ventilation system with heat recovery, you have the option of choosing between a centralized and a decentralized system. One central ventilation system organizes all air movements from a central device, usually installed on the roof or in the basement. It transports air from outside and inside to each connected room via a branched network of ducts. One central ventilation system offers high levels of heat recovery and good sound insulation. In addition, other functions such as: heat, cooling or humidification and dehumidification.

On the other side is this decentralized ventilation system, where each room or apartment has its own Ventilation unit has. These devices are independent of each other and do not require ducts as they draw in fresh air directly from outside and exhaust stale air to the outside. Decentralized ventilation systems are more flexible in their installation and are particularly suitable for smaller apartments or rooms where a central solution is not possible. They are characterized by simple Maintenance and lower investment costs.

The choice between a centralized or decentralized ventilation system depends on various factors and needs.

    What is the difference between a ventilation system with and without heat recovery?

    1. Customer Support - Advisor says:

      Hello Isabella,

      We are grateful for your feedback and your interest in our ventilation system with heat recovery test & comparison. Your support means a lot to us!

      This is an important question! A heat recovery ventilation system, also known as a decentralized ventilation system, has the advantage of being able to recover the heat that escapes through ventilation. With a ventilation system without heat recovery, the used air is simply discharged and replaced with fresh air from outside without recovering the thermal energy. A ventilation system with heat recovery, on the other hand, uses special heat exchangers to use the thermal energy in the exhaust air and to preheat the incoming air. As a result, less energy is required to heat the space, resulting in energy savings and lower heating bills.

      From our department: Greetings from the support team to Geesthacht.
