After looking at the wheelhouse and crew cabin, the next thing is the main event, the ice cabin.

Deep-sea voyages may even take a trip for a year or two at a time, and the ice cabin must be reliable, because the catch is in it, and if there is a problem with the ice cabin, then going to sea is a pure waste of money.

The most important thing in the ice cabin is the refrigeration effect, and Hanks said that they installed the most advanced refrigerator on the General Christian according to Qin Shiou's request.

There are generally three ways to preserve the catch: chilling, coiling and keeping it cold and fresh, freezing and refrigeration, and the ice tank of the harvest can also achieve these three effects, of course, the power of the refrigerator is not the same, and the volume of the ice tank is even different.

The most important refrigeration method for ordinary fishing boats is chilled refrigeration, which uses crystal clear ice cubes to chill seafood, which can often maintain the freshness of seafood to the greatest extent, and is low-cost, simple and easy to operate.

There is only one Xiaoice fresh refrigeration cabin on the General Christian, which is filled with about 100 tons of seafood.

The reason is very simple, the chilled refrigeration effect is the worst, at most fresh for ten days, for deep-sea fishing vessels, this period of time is too short, unless the ship is ready to go ashore to replenish oil grain and fresh water, it will be temporarily dry, with the chilled cabin to save some seafood ashore and sell.

The next highlight is coil keeping cold and chill refrigeration.

These two cooling methods are relatively costly, but if they are successfully cooled, the closure of the cabin can greatly reduce energy consumption.

"Lo and behold, we used polyurethane rigid foam for the ship's ice tanks, which is rarely used on ocean-going vessels because it's too expensive to build," Hanks said. But I have to say. Willing to invest in order to obtain big profits, this material has a good thermal insulation effect. After a single refrigeration, only a short period of additional cooling is required, compared to traditional polyethylene steel sheet materials. It retains up to 400% more heat. ”

Qin Shiou led people to inspect these two ice cabins, and the way to keep them cold and fresh was to have a pipe to continuously spray cold air into them, and always keep them at a low temperature. Freezing and refrigeration means that after the seafood is put into the ice cabin, the temperature is immediately lowered to below minus 10 degrees Celsius, and it is frozen into ice cubes.

The inspection method of freezing and refrigeration is simple, put a bucket of water in it, and the machine rumbles, and Qin Shiou can see it through the camera installed in the cabin. The water in the bucket froze at a visible rate, filling the bucket with water, and finally freezing into ice cubes that were higher than the edge of the bucket.

This is a very interesting natural phenomenon, we all know the principle of 'thermal expansion and cold contraction', but with the same mass of a bucket of water, the density of ice is less than that of water, so eventually when water turns into ice, it will become larger.

This property is important for living organisms because water is denser in solid states than liquids in the same way as most substances. In winter, the water at the bottom of the river, lake and bottom will freeze first, and the life below will not survive.

The early life on Earth originated in the oceans, and if the ice did not float on the water, even if there was life on the Earth, it would not be able to survive the ice age safely. So. This property of water and ice plays an important role in the survival of life on Earth.

Seeing the freezing effect, Qin Shiou nodded with satisfaction at Hanks and said, "Then." I'm going to look at the engine next? ”

Hanks took him to the aft engine room and proudly said, "The engine used on the General Christian is Ocean Pride from the Pratt-Whitney Group of Companies. The PP-LIKV556 engine belongs to the new generation of low-speed two-stroke diesel engine. At the same time, it is guided by a motor to ensure that the ship can make a flexible U-turn at any time. ”

Founded in 1925, the Pratt-Whitney Group of Companies is one of the two largest aero-engine manufacturing companies in the United States and one of the world's leading manufacturers of aero gas turbine engines.

Of course, engines are not separated, and the Pratt-Whitney group of companies is also strong in marine engines.

The motor guiding diesel engine is also the development trend of modern civil ships, and the motor here should actually be called the 'azimuth thruster', which can rotate 360° to make the ship more controllable and allow the hull to move in any direction.

However, the most advanced ship engine is the superconductor motor that Siemens has been working on in recent years, which is super wear-resistant and can adapt to various polar environments, such as the exploration of the Arctic Ocean.

After the inspection, everything is fine, Qin Shiou needs to sign the contract, and the next step is to pay the final payment.

Qin Shiou looked at the contract, pointed to the name of the ship and said: "I want to change the name of this ship, you negotiate with the shipping industry, and you will help handle the formalities, I don't want to call General Christian anymore, change it to Melon." If the name cannot be registered, it will be changed to Melon Princess. ”

With Hanks' calmness and wisdom, he couldn't help but gasp after hearing the name: "Melon No. It's a bit weird in the name. ”

Qin Shiou smiled kindly, pretending to ask casually, "How would you feel if you heard a little girl named Melon?" ”

Hanks thought about it for a moment and said, "If it's a cute little girl, then this name is great, melon is a very delicious fruit, and when used in the name, it will make me feel that this little girl is like a delicious melon, full of charm." ”

When Qin Daguan heard this, he patted Hanks on the shoulder and said, "You are very tasteful, I have to admit, man, no wonder we can always work together to make a business." ”

Waiting for Qin Shiou to leave, the sea monster looked at Hanks strangely and said, "Do you think a name like melon is suitable for a little girl?" ”

Hanks patted him on the shoulder and said, "Since my client likes to call his daughter melon, why shouldn't I?" What's more, it's not the first time I've talked nonsense with a clear conscience. ”

The sea monster laughed, then felt wrong, and asked in amazement, "How do you know that Qin's daughter is called Melon?" ”

"Melon Princess, man, wouldn't it be simple if you just had a daughter and you named a ship Melon Princess?" Hanks pointed to his head, feeling that the sea monster was in a state of concern.

Qin Shiou took a full range of photographs of the fishing boat, and then returned to the hospital to show Winnie, and said proudly: "I decided to name this ship the Melon Princess, what do you think?" ”

Winnie excitedly said, "Great, dear, I love the name so much." ”

"But," the conversation turned, and Winnie deliberately showed a dark expression, "when will the Empress Winnie come out?" ”

Qin Shiou immediately took out his mobile phone and said, "I'll add a fishing boat immediately, and it's called Queen Winnie!" ”

Winnie laughed and snatched her phone, waved her hand and said, "Forget it, I won't fight with my daughter, this fishing boat is named after her, I'm waiting for your luxury cruise!" ”

Qin Shiou hugged Winnie and said warmly: "There will be, dear, there will definitely be this ship." (To be continued......)
