Principle of work of the present utility model is to have adopted seawater refrigerating cycle and refrigerating coil, drives double evaporators with compressor conversion, makes under the fresh-keeping state of the remaining on of fishery products long period+3 ℃～-3 ℃, guarantees not dehydration of fishery products part, fresh, cleaning.At first form one group of fully enclosed seawater refrigeration work system by compressor, damping tube, oil separator, seawater formula condenser, device for drying and filtering, electromagnetic valve, expansion valve, seawater refrigerating evaporator, return-air electromagnetic valve.When system works, obtain+3 ℃～-3 ℃ freezing seawater by programming control, utilize freezing seawater to the strong cooling of fishery products spray, refrigeration, after the fishery products temperature reaches design temperature+3 ℃～-3 ℃, change over to again by threeway, device for drying and filtering, electromagnetic valve, expansion valve, coil evaporator, gas-liquid separator, return-air electromagnetic valve and enter same compressor, sea water condenser, form another group coil pipe sweat cooling system.The coil pipe refrigeration system works on, and makes when temperature fall is to-5 ℃ in the fish hold to quit work.At this moment, the sponge in the fish dish has suctioned the freezing seawater that sprays, and the coil evaporator tube-surface has also been formed bed thickness ice, the ice sheet actv. has been blocked main thermal source from the fish hold top, make fishery products remain on for a long time+3 ℃～-3 ℃ scope in, reached fresh-keeping, the purpose of insulation.
This specification sheets the 5th part and in conjunction with the accompanying drawings 1-14 showed full implementation example of the present utility model.Now be described in further detail: as Fig. 2-3.General conventional deep-sea fishing ship is 130～150T, and 2～3 fishery products cabins are all arranged, and each freezer volume is 40～75M
3, diesel engine that fishing boat is with is 50～75 horsepowers, the electrical generator of drive is 24 kilowatts.According to above condition, join one of the special-purpose refrigerating compressor of fishing boat, electricity consumption is 7.5 kilowatts, and 4 of water service pumps and other electrical equipment electricity consumption are 7 kilowatts, and equipment electric energy configuration aboard ship is rationally.By operating automatic guidance computer, heavy-current control case, compressor, oil extractor, sea water condenser, device for drying and filtering, electromagnetic valve, expansion valve, dry type high-efficiency evaporator, gas-liquid separator, accessory group, being assembled into a fully enclosed seawater refrigerating unit, it is installed in the fishing boat main engine room like this.Operation automatic guidance computer is installed in captain's operator's compartment.Coil evaporator is installed in three tops in the fishing cabin respectively, and couples together, form second sweat cooling system with the accessory group of refrigerating unit.
The filtering type sea water tank is installed on the fishing boat deck, with the APS plastic pipe various water pumps, electromagnetic valve, seawater electronic processors are coupled together, the spray pipeline is installed in the top (coil evaporator following) of three fish holds respectively, and the sense of the electronic temperature control temperature in the fish hold is popped one's head in to install.Connect all electric appliance circuits and enter the heavy-current control case, the equipment installation.
Marine operation begins fishing, but the fish of catching is respectively charged into cold-storage, holds in the fish dish of seawater, puts into the fishery products cabin, begins refrigeration; Refrigeration earlier with the seawater circularly cooling in the water tank to design temperature+3 ℃～-3 ℃.Start spray pump, in fishery products, fish dish, give fish, shrimp cooling freezing seawater spraying.Force when cold by the hydraulic accumulator at the bottom of the fish hold, sea water tank circulates jointly, stops to force cold when all dropping to design temperature up to fish, shrimp body temperature, cabin temperature.Computer program is transformed in the fresh-keeping program (force cold, fresh-keeping two kinds of job procedure can artificially be selected) automatically.When fresh-keeping, first seawater refrigeration, coil pipe freezes again, and coil pipe quits work when making the fish hold temperature reach-5 ℃, long-time insulation.Thereby reach fish, the fresh-keeping purpose of shrimp.When fishing cabin temperature build-up arrives+3 ℃ (space temperature, fishery products body temperature can guarantee below 0 ℃).The automatic job procedure of computer, by the indication of temperature signal, starting outfit begins fresh-keeping refrigeration for the second time automatically.The work refrigeration only needs 2 hours, and fresh-keeping, temperature retention time can reach 6～10 hours, has saved the equipment operation expense greatly.Fresh-keeping effect is safe and reliable, the quality height.Equipment is once break down, and because of good heat insulating, makes a return voyage in 20～36 hours, and fishery products qualitative change can not take place.
