An Empirical Study on the Ways of improvement in Chiller Efficiency by Variation of Various Performance Parameters

As well known, A chiller is a refrigeration system that cools a process fluid typically water, which is further used in commercial and industrial ways for process cooling or air-conditioning. With the help of such systems water can be cooled to temperatures as low as 5°C (~40°F) and pumped through a hydraulic circuit to reach the process equipment or the air handling units. Rather than water some other suitable primary and secondary refrigerants are also be used for such refrigeration purposes. For still lower temperatures glycol or brine solution may be used (also known as secondary refrigerants). A chiller would use either a vapour compression or absorption cycle to cool. Once cooled or chilled water is used in air-conditioning applications for cooling/dehumidification and thus creating comfortable and productive environments. A large amount of power is required to operate these system. This paper represents the possible and suitable ways of improving the performance of such systems because of maximization in performance is the key requirement of current running refrigeration chillers for energy saving point of view
