The human environment has a direct impact on the mood, physical condition, how to do it and generally all aspects of his life. Since a major part in the building of modern human life is going to create environmental conditions in the building, whether at work or at home, etc., is most important. If the most beautiful and precious buildings without heating, cooling or air conditioning will not be suitable for settlement. The main functions of this system include controlling temperature, humidity, wind speed, air, removing dust and other air pollution stink and, if necessary, to eliminate germs and bacteria in the air, heating and cooling air is proportional to the season.
The purpose thermodynamic property tables of this industry, providing optimum comfort indoors or under a certain condition is desired. Space seems to be building, residential, office, commercial, military, police, hotel, hospital, inside vehicles thermodynamic property tables (aircraft, cars, trains, thermodynamic property tables etc.), as well as specific areas such as manufacturing facilities, production of electronic thermodynamic property tables chips, pharmaceutical, health and ... is. Therefore, in order to provide favorable conditions and air conditioning in each of the places mentioned, different systems and is designed specifically for that location. Some of the criteria that the comparison of different systems for heating, thermodynamic property tables cooling, air Vthvyh form include:
Therefore, before any action is required to complete information from the budget, the desired degree of comfort, facilities and had the future expansion.
Anshan comfort conditions in different thermodynamic property tables environments through a series of on-air operations, such as an increase or decrease in the heat and humidity of the air and reduce the amount of gases and substances harmful to take hold. Air is a mixture of nitrogen, oxygen, Ar, carbon dioxide, neon, helium and other gases is negligible amounts. In addition to the amount of air that is Hmvarkhrtvbt gas rate is variable. To create favorable conditions it is necessary to examine the impact of these factors Kmtqabl and air conditioning systems thermodynamic property tables suitable to the conditions of the offer.
Relative humidity
It is a very broad topic and to all who enter the details of this topic is outside. Generally, when the temperature difference between two adjacent objects exist, heat from a hot object to a colder body to one of the following ways or a combination of them can Pzyrd:
It operates on natural gas or by blowing air movement is done. Natural thermodynamic property tables air circulation shift is done, the air is heated up and the cold air moves downward and thus a rotational flow is performed.
Depending on the temperature inside the walls of the building is less than or greater than the outside temperature, the amount of heat has to be driven into or out of the building. This value correlates well with wall heat transfer coefficient thermodynamic property tables which is directly related to gender wall.
The outside temperature is the average minimum temperature in summer outside in the winter, with a maximum temperature of outside air that has been recorded by the weather thermodynamic property tables over the past few years. It may be some days Yatabstan winter temperature is lower or higher than the average, but it rarely happens calculation thermodynamic property tables based on the conditions necessary to increase the capacity of heating or cooling thermodynamic property tables devices will be.
The terms of the temperature and relative humidity in residential and commercial building or office determined thermodynamic property tables on the basis of human welfare. In determining the design of the buildings due to the comfort of residents should be used in addition to the changes in the different parts of the air of each other or be done to the out on gradualism health Balancesheet The effects of display is. On the other hand, the relative humidity in the air quality and comfort of residents is important. With increasing drying temperature for the comfort of the residents do not change, we must reduce the relative humidity, and vice versa, in other words, in two different drying temperatures can be created if the human sense of the relative humidity Photos drying temperature change.
Kq usually negligible heat transfer structure and relatively constant throughout the year, because the soil temperature varies little throughout the year. Land should be a good dish to heat which can absorb thermodynamic property tables or lose large amounts of heat without changing temperature to within thermodynamic property tables 8 feet of the surface is substantially. Above this depth as we get closer to the surface soil temperature changes affect the outside air temperature becomes higher. The table below shows the amount of heat loss from the surface of the floor or basement walls are recommended. thermodynamic property tables
Apart from the above two methods for determining thermodynamic property tables the thermal load of the building there is a quick estimate:
Boo Rkly thermal load for most of the buildings between 20 and 60 per square foot, or 200 to 600 per square meter is estimated that an average of 25 to 40 per square foot and average 250 to 400 per square meter The warm climate with cold, he comes to the overall estimate.
Another way to estimate thermodynamic property tables the thermal loads more detailed estimate thermodynamic property tables of the total heat transfer through the wall and the heat load caused by the penetration of air. It can be used in accordance with the thermal load of the lining and then added together to estimate thermodynamic property tables the influence of air:
Seasons of the year when the temperature decreases, the energy thermodynamic property tables due to the temperature difference between indoor thermodynamic property tables air and ambient air from inside to outside of the body. Due to this, if the energy wasted by heating in the building
