Design method of non-equidistant nozzle air supply air conditioning systems in large-span space

In view of the uneven distribution of load in large-span space, based on the traditional jet formula method, an air supply design scheme of non-equidistant nozzles is proposed in this paper. Combined with the case of a hotel multi-function hall, how to design the non-equidistant nozzles according to the load distribution characteristics of the room is expounded, and the temperature field, velocity field and thermal comfort index (PMV, PPD, DR) of the air conditioning area are simulated by CFD software, and the results show that the scheme has achieved obvious improvement effect, and also verifies the feasibility of the non-equidistant nozzle air supply design method.
