【 摘 要 】

There is a necessity of low cost air conditioning (AC) systems for the agricultural sector of Pakistan e.g. product storage/preservation, greenhouse growing and thermal comfort of animals etc. Solid desiccant air-conditioning (DAC) system can be a handy solution in this regard. The present study gives a detail overview of DAC assisted with the Maisotsenko cycle (M-cycle) system and its applicability for the agriculture sector and livestock applications. Ideal humidity and temperature requirements for the agricultural and livestock applications have been represented on psychometric charts. Comparison between M-cycle assisted DAC and conventional DAC systems has been given which shows the significance of DAC technology in the AC sciences and also represented this difference as graphically. Desiccant AC systems are getting lots of attention in order to control the humidity in various air conditioning applications e.g. product storage, greenhouses and thermal comfort for the livestock. Different materials and arrangements of the desiccant air conditioning system are checked whether which arrangement is suitable for Pakistan situation. Additionally, some analysis has been made to investigate the DAC system assisted with M-cycle and checked the feasibility of system for ambient conditions of Multan. Results show that the DAC system can be low cost heat driven air conditioning system for the human comfort as well as agricultural sector of Pakistan.
