In this work, an opportunity to improve the seasonal utilizability of an indirect evaporative cooler integrated air-conditioning system is presented. The improved design recovers the waste heat from wet air passages by supplying them to the comfort zone of produce commodities whilst supplying the dry air to human-occupantscomfort-zone i.e. operating for dual purposes. The analysis is carried out for three different configurations of indirect evaporative cooler namely counter-arrangement, cross-arrangement, and multi-zonal (advanced) heat and mass exchanging devices. The performance of each integrated air-conditioning system is presented in terms of a 'special' mixing ratio, system capacity, and energy-efficiency-ratio. Results have shown that the waste heat from the wet passages can be exploited and the seasonal utilizability factors of the proposed air-conditioning system can reach up to 1.41, 1.13 and 1.34 for counter, cross, and multi-zonal indirect-evaporative coolers respectively. Afterwards, the system analysis for different climatic conditions has shown that it offers high performance in desert and semi-arid regions.
