Development of machine components for air ha

Purpose and goal

With the aid of VINNOVA a project was launched aiming to produce an efficient heat recuperation technology designed to fit the needs of renovation of residential buildings. Simulations suggested a series of optimized designs of a heat exchanger with high efficiency yet compact design. Two air handling units were designed and the performance of these designs were tested at the TÜV test laboratory in Munich. The goal to lay the foundation of a new series of air handling units was completed.

Expected results and effects

Simulations and test optimized the design of two heat exchangers. The result was a series of air handling units with high energy efficiency and low power consumption, specialized for installation in small areas with low ceilings. As a result, VoltAir will be able to provide a solution where energy efficiency is in focus and the installation area is limited. This will strengthen VoltAir system on a large and important segment in the market. Furthermore the knowledge of heat transfer and fluid dynamics was strengthened in the organization.

Planned approach and implementation

A market analysis initiated the project. A performance specification gave rise to a number of possible designs of a compact heat exchanger. As the demands of the production unit of VoltAir was defined the final solution was established. Through numerous simulations the final design was established and these heat exchangers were implemented in two air handling units. These were tested both in the production unit and at an external laboratory. The result of the project was a possible series of air handling units for the intended market segment.
