Chapter 062 Temperature Control

Both ends of the evaporator are connected with a chilled water circulation system. The heat absorbed by the refrigerant will lower the temperature of the chilled water, so that the low-temperature water flows to the user end, and then passes through the fan coil for heat exchange, and the cold air is blown out.

Working principle of wind system:

The transmission method of fresh air adopts the replacement type, rather than the internal circulation principle of air-conditioning air and the unhealthy practice of mixing old and new air.

The outdoor fresh air will be automatically sucked into the room through negative pressure, and when it enters the room through the fresh air outlet installed on the window of the bedroom, living room or living room, it will automatically remove dust and filter.

At the same time, the corresponding indoor pipelines are connected to the exhaust outlets in several functional rooms to form a circulation system that will take away the indoor exhaust gas and concentrate it on the exhaust outlet to "exhale", and the exhausted exhaust gas will no longer be recycled. Old and new wind form a good cycle.

Working principle of the coil system:

The working principle of the fan coil air conditioning system is to continuously circulate the indoor air with the help of the fan coil unit, so that it can be cooled or heated through the coil, so as to maintain the required temperature and certain relative humidity of the room.

The cold or hot water used by the coil is supplied by a centralized cold source and heat source.

At the same time, the fresh air that has been centrally processed by the fresh air air-conditioning machine room is sent to each air-conditioned room through a special fresh air duct to meet the hygienic requirements of the air-conditioned room.

Compared with the centralized system, the fan coil air conditioning system has no large air ducts, only water pipes and small fresh air ducts. It has the advantages of convenient layout and installation, small building space occupation, and good individual adjustment. It is widely used in temperature and humidity accuracy. Comfortable air conditioners with low requirements, many rooms, small rooms, and individual control.

Why did Zhou Wenwen suddenly want to do this?

In short, as long as you know that Zhou Wenwen failed to make this thing, but after doing so much, Zhou Wenwen is not easy to destroy directly, so he transformed it into a positioning GPS that can sense temperature, and now, there is nothing to stop it .

After receiving the signal from the chip, Zhou Wenwen on the ground took the flying sword and arranged the transmission towers on the top of the mountains, and immediately transmitted the signal to the communication satellite in geostationary orbit.

What, you ask why there are communication satellites here?

And this...well, the answer to the question is actually not that complicated. Zhou Wenwen intercepted it while watching the dawn world next door, and when he turned on the satellite, he didn't exhaust Zhou Wenwen to death.

Zhou Wenwen didn't expect geostationary orbit and communication satellites to be so difficult to get.

Geostationary orbit (or "Geostationary Synchronous Orbit", "Geostationary Satellite Orbit", "Clark Orbit") refers to a perfect circular geosynchronous orbit in which satellites or artificial satellites are perpendicular to the Earth's equator.

Geostationary orbit is a type of geosynchronous orbit.

Synchronous orbit means that the orbiting object (usually a satellite) has the same average orbital period as the orbiting object (usually a planet), and the direction is the same.

A circular orbit located at the equator is called a geostationary orbit.

Above the equator, the geosynchronous orbit has an altitude of 35,900 kilometers.

A concept in satellite orbit theory.

That is, a satellite orbit that is close to synchronous motion with the earth's rotation, or a satellite orbit in which the orbital period of a satellite around the earth is the same as that of the earth's rotation period.

The orbit of this satellite is close to a circle with a radius of about 36000km.

When a satellite orbits the earth, there is almost no relative motion relative to the ground, as if it is suspended in the air at rest, so it is called a geostationary satellite. Flying objects such as intercontinental communication satellites, meteorological satellites, and solar power stations planned to be launched in the 21st century are all is to take advantage of this orbital property.

The first person to propose the use of geostationary satellites for communications was Hermann Potosinik in 1928 (but not widely known).

GeeO.Smith mentioned geostationary orbit in the first story in the series of science fiction Veeral, which is the first time geostationary orbit has appeared in popular literature, but Smith did not discuss it in depth.

In 1945, the famous British science fiction writer Arthur C. Clarke published an article entitled "Extra-Terrestrial – Rocket Give Worldwide Radie?" in Wireless World, which explained the principle of geostationary orbit in detail, which also made geostationary orbit The concept spread widely.

Clark admitted that the concept of geostationary orbit he introduced was related to Smith's ThepleteVeral.

Clark was the first to clarify the role of the geostationary orbit for broadcasting and relaying communications satellites.

Therefore, sometimes the geostationary orbit is also called the Clark orbit.

Correspondingly, there is an area 35,786km above sea level called the Clark belt, which is located in the equatorial plane and can be used as a quasi-stationary orbit.

In addition, the circumference of the Clark orbit is about 265,000km.

A satellite or artificial satellite orbiting the Earth in this orbit is always at the same position on the Earth's surface.

Its orbital eccentricity and orbital inclination are both zero. The motion period is 23 hours, 56 minutes and 04 seconds, which coincides with the earth's rotation period, and the orbital radius is 42164.169km.

Since the sub-satellite track of a satellite moving in a stationary orbit is a point, observers on the surface can always observe the satellite at the same position in the sky at any time, and will find that the satellite is stationary in the sky, so many artificial Satellites, especially communication satellites, mostly use geostationary orbits.

On-orbit service technology in geostationary orbit is of great significance in promoting the development of economy, national defense and space technology.

The artificial satellite is relatively stationary with the ground ~lightnovelpub.net~ fixed above the equator. The prograde circular orbit is 35,786 kilometers above the ground, and the speed of the satellite is 3.07 kilometers per second.

A single satellite can cover about 40% of the Earth's area.

Meteorological satellites, communication satellites and broadcasting satellites often use this orbit.

In addition, some satellites of my country's Beidou satellite navigation system also use this orbit.

Radius comparison chart for Geostationary Orbit, Galileo, Global Positioning System (GPS), GLONASS, Beidou, International Space Station, and Hubble.

In addition, the lunar orbit radius (385,000 km) is about 9 times that of the geostationary orbit.

Satellites in geostationary orbit must all be distributed on the same circle over the equator.

During the operation, in order to avoid the satellites from bad frequency interference, the geostationary orbit satellites need to be placed separately, which means that the orbital position is limited, therefore, the number of satellites operating in the geostationary orbit is also certain.

Different countries will have conflicts in order to obtain the same geostationary orbit position (such as countries with the same longitude but different latitudes) and frequency resources. Such conflicts can be coordinated and resolved through the orbit allocation mechanism of the International Telecommunication Union.

In 1976, eight equatorial countries adopted the Bogotá Declaration, declaring that these countries have sovereignty over geostationary orbits over their territories, but this declaration has never been recognized by the international community.
