a single stage compressor, with constant (isothermal) temperature during the process, would remove the problems, but is impossible to achieve. multi-stage air compressor units with various cylinder configurations and piston shapes (figure above) are used in conjunction with intermediate and after cooling...
arrangements to avoid having an extended refrigeration circuit for cargo cooling, a brine system can be used. the brine is cooled by the evaporator and in turn cools grids or batteries. grids provide cooling which relies on convection and conduction but air circulated through brine batteries provides...
