Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further details.
In winter, sea ice acquisition system carries out adopting ice, and is transported in the interior each storage chamber main body 306 of ice storing car by sea ice by the defeated ice bank of plough 203.
Summer, the cold of cascade utilization sea ice and freshwater resources, sea ice modularization in each storage chamber main body 306 uses, namely the sea ice cold in a storage chamber main body 306 uses complete laggard row desalination process, sea ice simultaneously in another one storage chamber main body 306 carries out the utilization of cold, and cold uses complete laggard row desalination process.
Lower mask body describes sea ice cold and freshwater resources utilize process:
First, cryogenic energy utilization is carried out to the sea ice in storage chamber main body 306.Icehouse back-water valve (BWV) 421, water compensating valve 422 are opened, other valve closings; Feeding spraying pump 415 is opened, and other water pumps cut out.By carrying out moisturizing in moisturizing water inlet 417, sprayed in storage chamber main body 306 by feeding spraying pump 415.
When partition 308 with holes and lower floor partition with holes 309 is middle on upper strata for the water level of storage chamber main body 306, close water compensating valve 422, open the water pump 416 that draws water, icehouse feed water valve 420, frozen water direct-furnish feed water valve 411, frozen water direct-furnish back-water valve (BWV) 412, user's supply-water pump 408.Drawing water under water pump 416 and feeding spraying pump 415 effect, frozen water in storage chamber main body 306 is after filter 423 filtration, enter in heat exchanger 407 and form circulation, by heat exchanger heat exchange, by user's cold water supplying pipe 409, user's cold-water return pipe 410 and user's supply-water pump 408 externally cooling.
Along with the carrying out of cooling process, the sea ice in storage chamber main body 306 melts gradually and becomes water, constantly heats up.When the coolant-temperature gage in storage chamber main body 306 is elevated to uniform temperature, close frozen water direct-furnish feed water valve 411 and frozen water direct-furnish back-water valve (BWV) 412, open the freezing feed water valve 405 on frozen water indirect feed valve 413, the indirect back-water valve (BWV) of frozen water 414, freezing feed pipe 403, the freezing back-water valve (BWV) 406 on freezing return pipe 404, chilled water pump 402, handpiece Water Chilling Units 401.Water in storage chamber main body 306 feeds handpiece Water Chilling Units 401 condenser and serves as cooling water, and handpiece Water Chilling Units 401 carries out cooling by heat exchanger 407 couples of users under chilled water pump 402 acts on.
When the coolant-temperature gage in storage chamber main body 306 is elevated to more than local outdoor air wet bulb temperature, close handpiece Water Chilling Units 401, chilled water pump 402, freezing feed water valve 405, freezing back-water valve (BWV) 406, frozen water indirect feed valve 413, the indirect back-water valve (BWV) 414 of frozen water, icehouse feed water valve 420, icehouse back-water valve (BWV) 421, feeding spraying pump 415.Open simultaneously desalination water valve 419, the water pump 416 that draws water the water in storage chamber main body 306 is retracted to fade out the mouth of a river 418 carry out desalination process.
Next storage chamber externally carries out cooling simultaneously, and flow process is with above-mentioned storage chamber.When the cold in storage chamber main body 306 uses completely, desalination process is carried out to the water in storage chamber main body 306, re-uses the sea ice in next storage chamber main body, by that analogy simultaneously.
In autumn, in each storage chamber, carry out the sanitized concentrated.Upper strata partition with holes 308 and lower floor partition 309 with holes rides on supporting traverse, and conditioning in Transition Season detachably gets off, and enters storage chamber main body 306 and carries out hygienic cleaning to it, finally utilize slush pump to be discharged by sewage by workman.
Above with reference to drawings and Examples, schematically describe the utility model, this description is not restricted.Those of ordinary skill in the art will be understood that in actual applications, and in the utility model, some change all may occur the set-up mode of each parts, and other staff also may make the similar Design of various ways under its enlightenment.It is pointed out that only otherwise depart from design aim of the present utility model, all apparent changes and similar Design thereof, be all included within protection domain of the present utility model.
