Operational advantages of mobile refrigeration using a closed loop heat rejection configuration
Abstract
The operational advantages of localised cooling, in particular
moving the cooling source as close as possible to the area where
cooling is required, has been investigated by different authors over
a number of years. A notable advantage is the energy efficiency
potential associated with cooling locally, mainly due to the savings
obtained from a reduction in cooling water and the reduced
dewatering pumping power of water back to surface. The
challenges with supplying water from the cooling source to the
remote areas where the cooling is required led to the development
of mobile refrigeration units capable of providing localised
cooling. The developed mobile refrigeration air cooling unit (ACU)
alleviates some of these problems by increasing the amount of
cooling that can be done per litre of water available. These result
in more effective and energy efficient cooling, but these units do
however still require cooling water to operate. This paper looks
into the possible operational advantages, including energy
efficiency and reliability, when the condenser circuit of the ACU is
not connected to the main cooling water supply, but rather
connected in a closed loop heat rejection configuration with the
return airway (RAW)
