Maintenance trend analysis of air conditioning systems for ship operations in the Arabian Gulf

Emerson, Bradley E. 12 1900 (has links)
In December 2000, Program Budget Decision (PBD) 096 changed the way the Department of the Navy (DoN) budgets for Arabian Gulf operations. The cost of operations is now required to be submitted as part of the annual budget vice funded as contingency operations. In order to justify increased funding of incremental costs for operations in the Gulf, a method to justify such budget requests must be developed. This research developed a regression model targeted at the intermediate and depot level maintenance cost trends for Air Conditioning (A/C) systems based upon the assumption that the severe weather factors of the Gulf would impact the maintenance of A/C equipment. The model used ship age, deployed operational tempo (OPTEMPO), and temperature factors as explanatory variables in the model. The results of the regression analysis indicate the model does not provide evidence of increased maintenance costs of A/C systems for operations in the Gulf. Based on the inconsistencies in the maintenance data and the limitations of the explanatory variables, it is recommended that this approach be excluded from further research to justify increased budget requests for operations in the Gulf. / US Navy (USN) author

Economic analysis of various ground-source heat pumps compared to air-source airconditioners in South Africa

29 September 2015 (has links)
M.Ing. / In this study, alternative heat pump systems are compared for use in South African climatic conditions. Monthly heating/cooling capacities and coefficients of performance for air, vertical and several horizontal ground-source systems are calculated for Pretoria and Johannesburg. The desired type of heat exchanger is determined by considering economic factors such as the total costs, comprised of the capital and operating costs. The cost-effectiveness on investments of each system is calculated, with parameters such as the payback period, net present value and internal rate of return ...
