Live on a hot day with a high temperature on the ground floor or a high temperature on the upper flo

High-rise bar. If the north and south are transparent, it should be about the same.

The same heat, the height of the floor has nothing to do with the temperature, the heating regulations of various provinces and cities have clear provisions, the heating temperature must reach the specified temperature during the heating period, otherwise it is an illegal act, and the user can claim compensation.

Taking Qingdao City as an example, according to the "Qingdao Heating Regulations", it is stipulated that:

Article 31 The heating period is from November 16 of each year to April 5 of the following year (the people of Chengyang District, Huangdao District and county-level cities can appropriately adjust the heating period). During the heating period, the user's indoor heating temperature shall not be low to 18. The temperature in the kitchen must not be lower than 10.

The heating unit shall conduct a trial heating supply five days before the start of the heating period, and do a good job in commissioning and exhausting.

What are the effects of temperature in <> high-rise buildings?

The high-rise building structure is a high-order superstatically determined structure. When the superstatically determined structure is affected by temperature change and ballast ear, internal forces and deformation will occur in the structure.

Initially, in order to reduce or avoid the effect of temperature changes, people often used thermal insulation measures to hide the structure in the façade wall, so that the structure was placed in a constant temperature environment and was not affected by external temperature changes. However, for reinforced concrete high-rise buildings, the design scheme of exposed structure is generally adopted. In this case, the internal forces of the structure must be affected by the change in the external temperature.

There are three main types of temperature changes that cause the internal force of the temperature of high-rise building structures, namely: indoor and outdoor temperature difference, sunshine temperature difference and seasonal temperature difference.

As a rule. The binding force in the structure caused by the change in dry humidity is proportional to the number of floors in the structure. Structural deformation caused by temperature changes is generally as follows:

1 column bending.

Due to the temperature difference between indoor and outdoor, one side of the outer column expands or the other side shrinks, and the uneven strain in the column section causes bending.

2 Expansion and contraction difference between the inner and outer columns.

The axial expansion and contraction of the outer columns are affected by the temperature outside the room and the temperature of the indoor air conditioner are inconsistent, which causes the out-of-plane shear deformation of the floor structure.

3. The expansion and contraction difference between the roof structure and the lower floor structure.

With the influence of seasonal sunshine, the thermal expansion and cold contraction of the exposed roof structure changes greatly, and the temperature change of the lower floor structure is small, and the shear deformation and shear cracks of the wall will be caused by the unequal expansion and contraction of the horizontal components of the upper and lower floors.

Generally speaking, for buildings with less than 10 floors, and when the building plan length is less than 6om, the effect of temperature change is negligible. For buildings with 10 to 30 floors, the deformation caused by the temperature difference gradually increases. The magnitude of the temperature effect mainly depends on the degree of exposure of the structure, the stiffness of the floor structure and the height of the structure.

As long as the building insulation structure and the structural reinforcement structure are properly treated, the role of temperature can still be ignored in the calculation of internal forces. For super high-rise buildings with more than 30 floors or more than 10om, attention must be paid to the effect of temperature in the design to prevent structural and non-structural damage of the building.

At present, in China, there is no specific regulation on how to consider the role of temperature in the structural design of high-rise buildings. Accurate and practical calculation methods of internal forces and specific and effective structural measures need to be further studied.

Second, what should I do if it's cold, tired and unmotivated?

The most important thing is what you can learn in the company and whether it is beneficial to your development.

This involves the problem of ground radiation, the heat source of the atmosphere is ground radiation, so when the high-level large tank gas is farther away from the ground, the temperature will be lower, but after rising to a certain height, the ground radiation is almost 0, and the upper atmosphere is affected by infrared ultraviolet rays (that is, solar radiation) and cosmic materials, etc., and gradually warms up, so the temperature of the upper atmosphere will first drop and then rise with the increase of altitude.

1. The reason why the temperature in the upper atmosphere first falls and then rises.

1) Temperature drop zone: It is because there is no ozone in this layer, and the temperature drops.

2) Temperature rise zone: This is due to the fact that the sun's ultraviolet radiation, whose wavelength is smaller, is absorbed by atmospheric substances (mainly atomic oxygen) in the layer. The degree of warming is related to solar activity, and when solar activity intensifies, the temperature increases with altitude.

2. Properties of the upper atmosphere.

The thermal state of the upper atmosphere is controlled by the heating of solar ultraviolet radiation, which makes the atmospheric temperature above 80 km increase with the increase of altitude, and change with time, latitude and longitude, solar activity, magnetospheric disturbance, etc. The sun's ultraviolet radiation causes the decomposition of oxygen molecules in the upper atmosphere. The sun's ultraviolet radiation and X-rays in turn ionize the N2, O2 and O to form the ionosphere.

Particles in the upper atmosphere are excited by solar radiation and bombarded by solar energetic particles, which can produce luminous phenomena such as gas glow, noctilucent clouds, and auroras.

1 All must be a little lower.

This is related to two concepts: the rate of decline in wet adiabatic and the rate of increase in dry adiabatic I take a picture of the overall image, a cloud of air has to cross a 1000-meter mountain, and the air is 20 degrees at the foot of the mountain. Then the air climbs, and for every 100 meters of ediabatic dampness, the temperature drops.

In the process of falling temperature, the water vapor in the air condenses, forming precipitation. After precipitation, the air climbs over the top of the mountain and begins to descend, at which point the temperature rises by 1 degree for every 100 meters of altitude drop, according to the dry adiabatic rate. Therefore, the air temperature is 20-6 = 14 degrees Celsius at the top of the mountain, and 14 + 10 = 24 degrees Celsius after descending, which also produces a foehn effect.

Although the above is an explanation for the foehn effect, it also fully shows that the temperature in the higher altitude area is relatively lower than that in the lower altitude area. This is mainly due to the concept of the rate of decline in damp adiabatic.

The water and carbon dioxide in the air in the stratosphere can absorb the long-wave radiation in the sunlight and emit it to the ground in the form of heat, and the ground is reflected to the clouds at night, the clouds in the plateau area are thin, so the temperature is low, and the temperature difference between day and night is also large.

It's not much low, and the estimated temperature difference is only a few degrees.

There are three types of heat conduction: direct heat conduction, convective heat transfer, and heat radiation.

Answer: 1. The high-rise has more solar radiation heat than the low-rise, and the floor of the constructed wall has heat storage. Not only is it hot during the day, but it can also be hot continuously at night.

2. The radiation heat exchange between the high-rise and the earth is less, and the radiation heat transfer between the low-rise and the earth is more. The so-called radiation heat exchange means that I radiate you, and you radiate me; Whoever has a high temperature and who has more radiation; Who has a large three-dimensional angle in space, and who bears more radiation. As a result, the temperature of the ground is more uniform and always lower than the ambient temperature (as usual), so a lot of heat is given to the earth in the lower layers.

Therefore, an answer upstairs gives the conclusion that the mountain is cool. On the one hand, the ambient temperature in the mountains is low, and on the other hand, the house is radiant to the earth, and the radiation heat exchange between the mountains is also cool.

<>3 The influence of wind varies greatly in different areas, and the arrangement of buildings in the community also has a great impact. Therefore, the high-rise areas with many trade winds in summer are also cool, which is important for the characteristics of China's eastern coastal areas. The subject of high-rise heat is eighty percent of the local area, and the summer monsoon is rare.

These three points do not affect each other, and they fundamentally affect the indoor temperature independently.
