Comparative assessment of annual energy consumption in the central and decentralized air conditioning systems
Annotation
In article the decentralized air conditioning system (ACS) representing a combination of the central conditioner (CC) and local system are considered. The concept of adjacent system of a microclimate is given. As systems of adjacent systems in article air coolers and adiabatic humidifiers are considered. It is shown that use of the decentralized hard currencies allows to reduce significantly dimensions of the Central Committee in comparison with the central hard currencies at the expense of increase in adjusting productivity of adjacent system. But in too time from the given examples it is visually visible, annual expenses of the consumed energy resources how significantly increase if instead of central to use the decentralized hard currency. The importance of use of thermodynamic potential of air of the second recirculation is analysed. On examples it is shown that its use allows to cut down significantly expenses of the consumed warmth and "cold" without increase in dimensions of the Central Committee.
