Definitions

  • This invention relates to a cooling system for the hold of a container ship.
  • the system is intended for cooling the cargo hold of container ships for carrying refrigerated food containers.
  • Food containers are provided with an intra-container refrigeration system, having its condenser outside the container.
  • the condenser generates heat in the cargo hold, and the resulting heat, as well as its ventilation, limit the number of containers carried in the hold.
  • a cooling system of the invention is characterized in that the cooling system further comprises a fan for blowing refrigerated air along a duct system to the condensers of cooling containers, and a cooling radiator, through which the cooling water chilled by a refrigeration compressor is circulated by means of a cooling water pump.
  • the basic idea is to fit a shipping container inside the cargo hold with refrigeration equipment and fans, capable of blowing refrigerated air along air ducts to the condensers of refrigerated containers constituting a cargo. Cold air chills the condenser and maintains the cargo hold temperature at +45° max.
  • the cargo hold is sealed in a watertight manner by cargo hatches on deck and, thus, constitutes a reasonably tight compartment.
  • the air blown to condensers warms up in a condenser and returns back to the cooling container by way of a recirculation air opening to serve as recirculation air and is refrigerated further and blown back to condensers in the cargo hold.
  • the cooling container's automation can be used for managing cargo hold conditions from the bridge and the engine control room, and for monitoring temperatures of containers carried as a cargo.
  • the cooling container is constituted by a standardized 20- or 40-foot long steel container.
  • the container houses a refrigeration compressor 2, which is fitted sea water condensing pumps 7.
  • a pipework 10 extends to a sea water tank.
  • the refrigeration compressor is provided with a condenser 11 and an evaporator 12. Cooling water chilled by the refrigeration compressor is circulated by cooling water pumps 6 through cooling radiators 5.
  • the cool water refrigerates air circulating from a cargo space by way of a return air duct 8, said air being blown back to the condensers of cargo containers by means of fans 3 along an inlet duct system 4.
  • the container Inside the container 1 is fitted a cooling water pipe system 9, a sea water condensing pipe system and pipe system fittings.
  • the container also houses all actuators or starters required by the pumps, the refrigeration compressor, and the fans.
  • Work stations for system control equipment are set up on the bridge and in the control room (ECR).
  • the work stations and the containers are interconnected by way of a bus.
  • 20-foot long containers used as cooling containers can be set on top of each other, such that the lowermost containers are provided with refrigeration equipment and the topmost containers are provided with fans and cooling radiators.
  • the cooling containers may also comprise 40-foot containers and 20-foot containers in various combinations, depending on the size of a cargo compartment.
  • Refrigeration equipment can also be taken out of the containers and placed outside the cargo compartment in a space provided in a separate system.
