Analysis of Hydrodynamic Behavior of Windbreaks in the Average Internal Temperature of Semi-Warm and Arid Climates in Kashan with the Aim of Greater Efficiency

One of the ways to achieve a building with higher energy efficiency and an efficient system is to use local architectural experiences. In the meantime, a windbreak is one of the elements used in the past to create comfort in Kashan's hot and dry climates. The interior of these settlements in this climate aims to greater efficiency of this element by CFD software, Energy Plus, and Open Studio with a descriptive-analytical method and then analyzed the results.  It has water spray, and one of the leading causes of temperature drop in these wind deflectors is the proportionality of the dimensions-the air inlet valve to the wind deflector, water temperature, dimensions, and height of the wind deflector column. Iranian indigenous architecture's interaction with the climate is a deep and ancient interaction that has long been using its experiences and techniques to create an architecture with maximum energy savings in Iran's climatic areas. The process of formation of these techniques in the length of time and in order to adapt to the climate while utilizing the natural force in the environment has created a suitable natural space for users. Innovative technology reduces the long-standing concern of architects in saving and optimizing energy consumption in buildings. In the meantime, the windbreak is one of the elements used in the past to create comfort in Kashan's hot and dry climates. They were used to move and cool the air in the building. The primary function of the wind deflectors was to direct the outside air into the building, relative cooling by establishing a flow at work and people living in different cities and places. Research has proven that the wind deflector is a suitable device for natural ventilation of the indoor air to reduce the internal temperature of the building and create thermal comfort for the residents. Traditional windbreaks are correctly designed according to the day's needs and have been widely used in hot and dry areas of Iran. What is certain is that the use of this element in today's world requires its adaptation to today's life. Today's cities and buildings have different faces, and windbreaks are limited. And analyze how it operates in terms of form and function. Comparison of the results of the analysis of wind speed in wind turbines and how the wind is oriented in the interior shows. Due to the low thermal mass of the windbreak walls compared to the room, the temperature fluctuation is always higher than the room. To reduce the room temperature further, the priority is to use a spray windshield over windshield wipers. Especially, windshields with water spray in which most of the room has a temperature of 298 K are approximately equal to 25 degrees Celsius and are in Kashan city's thermal comfort range. One of the main factors in this Temperature drop proportionality of dimensions- air inlet valve to the windshield, water temperature, measurements, and height of the windshield column.
