Proposed project is dealing with design of innovative air handling unit for local air treatment which is using thermoelectric modules. The aim of the project is to develop unit prototype including smart control module with measurement of indoor air quality and control algorithms taking available renewable energy into account. Using the support from the technical agency the project development will speed up and more personal capacities will be assigned to the development. The functional prototype will be developed within the project and will be introduced in the last year of the project 2023. Intellectual property will be also protected within the project.
