| Abstract | This research work examines the design of an air conditioning process. The various steps in the air conditioning process are described in this paper. A range of air conditioning layouts, mixing proportion of fresh air with re-circulated air, human comfort settings, and estimating the best supply condition is described in the paper. Comfort air conditioning is established based on accepted engineering standards from ASHRAE (The American Society of Heating, Refrigerating and Air-Conditioning Engineers). The cooling coil, an integral part of an air conditioning system, is a finned cross-flow heat exchanger. The design of the cooling coil is modeled using various secondary refrigerants. Secondary refrigerants considered in this work are conventional chilled water and ionic liquid-water mixtures. The use of ionic liquid-water mixtures as a secondary refrigerant in an air conditioning process is a new concept that is yet to be documented in technical literature. The use of ionic liquid-water mixtures as heat transfer fluid in sensible heating and cooling applications has been studied due to the ionic liquid's physical characteristics such as chemical and thermal stability, non-volatility, tunable solubility in water, etc. In this work, four different kinds of ionic liquid-water mixtures are considered as a secondary refrigerants for the cooling coil. The design of the cooling coil is considered on a dimensionless basis, and the parameters relevant to steady-state heat exchanger modeling are applied herein. In the study, for the given operating conditions and cooling load, both chilled water and ionic liquid-water mixtures required a similar number of transfer units (NTU) for achieving the desired heat transfer. |
