Chapter 1013

I've seen the cockpit and crew cabin, and then the highlight, the ice cabin.

Deep sea voyage may even be a trip for a year or two. The ice cabin must be reliable, because the catch from fishing is here. If the ice cabin goes wrong, going to sea is a pure waste of money.

The most important thing in the ice cabin is the refrigeration effect. Hanks said that they installed the most advanced refrigerator for the general Kristen according to Qin Shiou's requirements.

The refrigeration methods of fishing boats are similar. Generally, there are three ways to preserve the catch: fresh ice, coil cooling and fresh ice, freezing and refrigeration. The ice cabin of Fengshou can also achieve these three effects. Of course, the power of the refrigerator is different, and the volume of the ice cabin is even different.

The most important refrigeration method for ordinary fishing boats is ice fresh refrigeration. The seafood is iced with crystal clear ice, which can often keep the seafood fresh to the greatest extent, with low cost, simple and easy operation.

On the general Kristen, however, there is only a small ice fresh refrigeration cabin, which is filled with about 100 tons of seafood.

The reason is very simple. The refrigeration effect of ice fresh is the worst, and it can keep fresh for up to 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 temporarily do a sum of money, save some seafood in the ice fresh cabin and sell it ashore.

The next important play is coil cooling, freezing and refrigeration.

The cost of these two refrigeration methods is relatively large, but if the refrigeration is successful, closing the cabin can greatly reduce the energy consumption.

Hanks said, "look, we used polyurethane rigid foam material for the ice cabin of this ship. This material is rarely used in ocean going ships because its cost is too high. However, I have to say that only if we are willing to invest can we make a big profit. The thermal insulation effect of this material is very good. Only a short additional refrigeration is required after one refrigeration. Compared with the traditional polyethylene steel plate material, its thermal insulation effect can be improved by 400%. "

Qin Shiou took people to check the two ice tanks. The way to keep the coil cold and fresh is to continuously spray cold air into the pipe to keep the low temperature all the time. Freezing and refrigeration means that after the seafood is sent to the ice cabin, the temperature is immediately reduced to below minus 10 degrees Celsius and frozen into ice.

The inspection method of freezing and refrigeration is simple. Put a bucket of water in and the machine roars. Qin Shiou can see through the camera installed in the cabin that the water in the bucket is frozen at a speed visible to the naked eye. A bucket of water is full, and the ice finally frozen 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 cold contraction" is well known. However, the same bucket of water has the same mass, and the density of ice is less than that of water. Therefore, when water turns into ice, its volume will become larger.

This characteristic is very important for organisms, because if water, like most substances, has a solid density greater than the liquid density, it will freeze the water at the bottom of rivers, lakes and seabeds in winter, which will make underwater organisms unable to survive.

The early life on earth originated from the ocean. If the ice can't float on the water, even if there is life on earth, it can't survive the ice age safely. Therefore, the characteristics of water and ice play an important role in the survival of life on earth.

Seeing the freezing effect, Qin Shiou nodded to Hanks with satisfaction 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 Kristen is the marine pride from Pratt Whitney group, pp-likv556 engine, which belongs to a new generation of low-speed two-stroke diesel engine. At the same time, it is guided by an electric motor to ensure that the ship can turn around flexibly at any time."

Pratt Whitney group, founded in 1925, is one of the two largest aviation engine manufacturers in the United States and one of the world's major aviation gas turbine engine manufacturers.

Of course, engines are not separated, and Pratt Whitney group has strong strength in marine engines.

The motor guided diesel engine is also the development trend of modern civil ships. In fact, the motor here should be called "azimuth propeller", which can rotate 360 ° to make the ship more controllable and make the hull move in any direction.

However, the most advanced ship engine is the superconductor motor studied by Siemens in recent years. It is super wear-resistant and can adapt to various polar environments, such as the exploration of the Arctic Ocean.

After the inspection, everything is OK. Qin Shiou needs to sign the receipt contract, and then he has to pay the balance.

Qin Shiou looked at the contract, pointed to the name of the ship and said, "I want to change the name of the ship. You can negotiate with the shipping company, and the formalities will be handled with your help. I don't want to call general Kristen, but melon. If the name cannot be registered, it will be changed to melon princess. "

With Hanks's calmness and wisdom, he couldn't help taking a breath after hearing the name: "melon? The name is a little strange. "

Qin Shiou smiled kindly and asked casually, "what would you feel if you heard a little girl named melon?"

Hanks thought about it and said, "if it's a lovely little girl, the name would be great. Melon is a very delicious fruit. When used in the name, it will make me feel that the little girl is like a delicious melon, full of charm."

After hearing this, the senior official of Qin was immediately happy. He patted Hanks on the shoulder and said, "you have good taste. I have to admit, man, no wonder we can always do business together."

When Qin Shiou left, the sea monster looked at Hanks strangely and said, "do you think the name 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 don't I like it? Besides, it's not the first time I've talked nonsense against my conscience. "

The sea monster laughed, then felt wrong and asked, "how do you know Qin's daughter's name is melon?"

"Melon princess, man, if you just had a daughter and named a ship melon princess, what does that mean? Isn't it very simple?" Hanks pointed to his head and felt that the sea monster's IQ was worrying.

Qin Shiou took all-round photos of the fishing boat, then returned to the hospital to show it to Weini, and said proudly, "I decided to name this ship melon princess. What do you think?"

Winnie said excitedly, "great, honey, I really like the name."

"But," as soon as the conversation turned, Winnie deliberately showed a cloudy expression, "when will the queen Winnie come out?"

Qin Shiou immediately took out his mobile phone and said, "I'll add a fishing boat right away. It's called queen Winnie!"

Winnie smiled and grabbed the mobile phone, waved her hand and said, "forget it, I won't argue with my daughter. This fishing boat is named after her. I'm waiting for your luxury cruise ship!"

Qin Shiou picked up Weini and said tenderly, "there will be, honey, there will be this ship."
