AE-86-13  aA thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Environment, Resources and Development  aThesis (M.Eng.) - Asian Institute of Technology, 1986  aAs the Asian farmers can not afford to pay for the costly  air conditioned cab on the tractor, it was thought worth  while to investigate the technical feasibility of providing  thermal comfort to the operator , by low-cost methods other  than air-conditioning.  With this view in mind , an experimental low cost  tractor cab was constructed and eight sensible and two  evaporative cooling systems were studied for their technical  feasibility in providing thermal comfort inside a tractor cab  during the summer of1986 in the experimental farm of Asian  Institute of Technology, Bangkok. It was concluded that the  system (cab with four side open , all the sides with  external shade and with fan cooling having air movement from  inside to outside ) was found to be t he most effective  sensible cooling system The cab with shade and evaporative  cooling was found to be the best of all ~he systems. The  later could achieve an average inside temperature of 29-30  degree C with inside heat stress index value below 30 in a  summer environment which has outside dry bulb temperature of  39 - 40 degree C and outside heat stress index of 140  Therefore it is recommended to adopt the evaporative cooling  system with shade both for economy and comfort of the  operator in tropical climate. 0aTractors1 aGupta, Chandra P., eChairpeson1 aGee-Clough, D.,eExamination Committee1 aSingh, Gajendra,eExamination Committee2 aRoyal Norwegian Government, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
