Benefits From Combination of Centralized Ventilation System and Decentralized Conditioning Units

Each building needs to have regulated temperature as well as needs to be ventilated. These two requirements come from one of most important function of the building: create comfortable indoor climate. A human being need fresh air to stay healthy and fit. The building need to be thermal conditioned from one side to protect the construction and the mass of the building and because of thermal indoor comfort for a user’s. The both needs relate to energy consumption but also with a place (volume) in a building. So, there are both investments cost and consumption costs.Benefits for both can bring the system witch splits those to needs – hygienic and caloric – and bring a combination between centralized ventilation system and decentralized conditioning system. In this the air exchange is provided by a single bidirectional ventilation unit. The temperature is adjusted on this system by decentralized equipment in the inside of the room and not via the central ventilation unit (air handling unit).This combines the unbeatable efficiency of decentralized units with the heat recovery capability of a ventilation unit.The basic system will be presented and compared. The central-decentral system will be described in detail and all the benefits for the building energy consumption and other system component like BMSystem, architecture will be mentioned.The presentation will present a separately working centralized ventilation unit and decentralized conditioning units with are connected into one system.
