After seeing the cab and crew cabin, the next step is the highlight, the ice cabin.

A long-distance voyage in the deep sea may even be traveling for one or two years at a time. The ice cabin must be reliable because the fishing catches are all here. If the ice cabin is out of trouble, going to sea is a pure waste of money.

The most important thing in the ice cabin is the refrigeration effect. Hanks introduced that they installed the current most advanced refrigeration machine for General Christine in accordance with Qin Shiou's requirements.

The refrigeration methods of fishing boats are similar. There are generally three ways to preserve the catch: chilled, coiled tubes keep cold and fresh, frozen and refrigerated. The ice cabin of Fenghunter can also achieve these three effects. Of course, the power of the refrigerator is different, and the volume of the ice cabin is even more different.

The most important refrigeration method for ordinary fishing boats is to refrigerate freshly. Use crystal clear ice cubes to chill seafood, which can often keep seafood fresh to the greatest extent, and is cheap and easy to operate.

There was only a small chilled refrigeration chamber on General Christan's No. 100 tons of seafood.

The reason is very simple. The cold and fresh refrigeration effect is the worst, and it can be kept fresh for up to ten days. For deep-sea fishing vessels, this period is too short. Unless the ship is ready to go ashore to replenish oil, grain and fresh water, it will be temporarily dried. Save some seafood in the chilled cabin and sell it on the ashore.

The next highlight is to keep the coil cold and freeze and refrigerate.

These two refrigeration methods are relatively expensive, but if they are successfully refrigerated, closing the cabin can significantly reduce energy consumption.

Hanks introduced: "Look, we used polyurethane hard bubble material for the ice cabin of this ship. This material is rarely used on ocean-going giant ships because it is too expensive. But I have to say that you can only make a big profit if you are willing to invest. This material has a good insulation effect. After one refrigeration, you only need to briefly perform additional refrigeration. Compared with traditional polyethyl steel plate materials, its insulation effect can be increased by 400%.

Qin Shiou led people to check these two types of ice cabins. The way to keep the coils cold is to keep air-conditioned in the pipes, and always keep the temperature low. Freeze and refrigerate. After sending seafood into the ice cabin, the temperature will be immediately reduced to below minus ten degrees Celsius and frozen into ice.

The inspection method of freezing and refrigeration is simple. Put a bucket of water in it. The machine rumbling. Qin Shiou could see through the camera installed in the cabin that the water in the bucket freezes at a speed visible to the naked eye. A bucket of water is full, and the frozen ice cube is higher than the edge of the bucket.

This is a very interesting natural phenomenon. As we all know, the principle of "thermal expansion and contraction", but the same mass of a bucket of water, the density of ice is smaller than that of water, so when the water turns into ice, the volume will become larger.

This characteristic is very important to organisms, because if water is as solid-state density as most substances is greater than liquid density, then the water at the bottom of rivers, lakes and seabeds will freeze first, which will prevent the bottom of the organisms from surviving.

Early life on Earth originated from the ocean. If ice cannot float on the water surface, even if there is life on Earth, it will not be able to safely pass the ice age. Therefore, the characteristics of water and ice play an important role in the survival of organisms on Earth.

Seeing the freezing effect, Qin Shiou nodded with satisfaction to Hanks and said, "So, I'll go and see the engine next?"

Hanks took him to the engine room at the stern and proudly introduced: "The engine used by General Christine is the PP-likv556 engine from the Platt-Whitney Group, which belongs to the new generation of low-speed two-stroke diesel engines. At the same time, it is guided by a motor to ensure that the ship can turn around flexibly at any time."

Founded in 1925, the Platt-Whitney Group is one of the two largest aero engine manufacturing companies in the United States. It is also one of the world's leading aviation gas turbine engine manufacturers.

Of course, the engines are not divided, and the Pratt Whitney Group is also very strong in marine engines.

Motor-guided diesel engines are also the development trend of modern civilian ships. The motor here should actually be called the 'azimuthruster'. It can rotate 360°, making the ship more controllable and allowing the hull to move in any direction.

However, the most advanced steamship engine is the superconducting motor that Siemens has been studying in recent years. This thing is super wear-resistant and can adapt to various polar environments, such as the exploration of the Arctic Ocean.

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

Qin Shiou looked at the contract and pointed to the ship's name: "I want to change the name of this ship. You will negotiate with the shipping industry. You will help you handle the procedures. I don't want to call General Christan again, but change it to Melon. If this name cannot be registered, it will be changed to Melon Princess."

With Hanks' calmness and wisdom, he couldn't help but take a breath after hearing this name: "Melon? This name is a bit weird."

Qin Shiou smiled kindly and pretended to ask casually: "What would you feel if you heard a little girl named Mu.?"

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

When Qin Daguanren heard this, Long Yan was very happy. He patted Hanks on the shoulder hard and said, "You are very tasteful, I have to admit, man, no wonder we can always join forces to start a business."

When Qin Shiou left, Hai Wei looked at Hanks strangely and said, "Do you actually think a name like Melon is suitable for a little girl?"

Hanks patted his shoulder and said, "Since my client likes to call his daughter Melon, what reason do I don't like? Besides, it's not the first time I've been talking nonsense against my conscience."

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

"Muzzle Princess, man, if you just had a daughter and then named a ship Melon Princess, then what does that mean is not very simple?" Hanks pointed to his head, feeling that the sea monster's IQ was worrying.

Qin Shiou shot the fishing ferry in all aspects, then returned to the hospital to show it to Winnie, and said proudly: "I decided to name this ship the Melon Princess. What do you think?"

Winnie said excitedly: "Great, my dear, I really like this name so much."

"But," the conversation changed, and Winnie deliberately showed a gloomy expression, "When will the Queen of Winnie come out?"

Qin Shiou immediately took out his cell phone and said, "I will add a fishing boat immediately, and it will be called Queen Winnie!"

Winnie laughed and snatched her phone, waved her hand and said, "Forget it, I won't argue with my daughter. This fishing boat is named after her. I'll wait for your luxury cruise ship!"

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