Modern Air-Conditioning Systems without Wiring Duct

Abstract

The calculation involved in the design of integrated heat-hydraulic air-conditioning system in which air is supplied through the raised floor was presented. Calculations were made using the premises of an office building in Yekaterinburg, Russia. Raised floor in the current study was presented in the form of a channel with a concrete wall on one side and chipboard -on the other. It has been successfully established that the loss of pressure during air movement in the raised floor space is minimal, this was suggested as a result of the possible uniformity in air supply to the air distributors. It was also demonstrated that due to transmission losses through the walls of the raised floor, the cooling capacity of the air conditioning system was significantly reduced (up to 15%). Following the results obtained, conclusions were drawn about the main features of such systems. © Published under licence by IOP Publishing Ltd.
