This paper describes a simulation program which was developed for the modelling of air-conditioning systems and conditioned spaces in industrial buildings. The program can be used for a design of systems for new buildings and for analysis of existing ones. By viewing the building as a dynamic entity, it is possible to investigate how thermal capacity of the building elements acts on both the conditioned space and the performance of the air-conditioning system. The program simulates three important aspects of a building.
This paper deals with the elaboration and the validation of a userfriendly numerical program (EOL) for the calculation of the ventilation patterns inside industrial premises. After the running-in. In period, "EOL" will be used by the technical staff in charge of ventilation projects. Here is set out the EOL unit devoted to the calculation of the mean flow inside the rooms. The structure of the software (presently restricted to two-dimensional mean flow configurations) is explained.
The paper compares air infiltration rate measurements with air leakage measurements in a modem industrial building. In each case the tests have been performed firstly with the building 'as-built', and then with the major leakage components sealed. The building investigated was of a cladding wall construdion with U-values of 0.6 W.m^-2.K^-1 for both the walls and roof. It had a floor area of 466 m². The volume was 3050 m³. Tracer decay tests and constant concentration methods (both using N20) were performed in the building to establish the air infiitration rates.
