Determination the installation efficiency of the evaporative air cooling in the greenhouse by temperature-moisture regime

Abstract

The results of theoretical studies and experiments of the developed exhaust ventilation system with direct evaporative air- cooling with using “wet mats” are given. It has shown sufficient efficiency with increasing quality of flower cutting in the summer months. The effect of moisture on the operation of this system was studied. It is established that the heat absorption capacity of air directly depends on its temperature and relative humidity. It is also determined that the temperature of leaves and flowers in summer is usually 2 ÷ 7 °C greater than the air temperature in the greenhouses. In an experimental greenhouse, according to the results of experiments, the effectiveness of the developed installation for evaporative cooling of its operation was determined.

Mathematical modeling of heat and mass exchange processes in the evaporative cooler

“…Today, great attention is being paid to one of the country's most important economic sectors -the construction of technological equipment for the energy industry, which takes into account modern requirements, such as air conditioning and cooling systems [1,2]. Energy efficiency is a key component of Uzbekistan's 2017-2021 Strategic Action Plan, which emphasizes reducing energy and resource consumption in the economy through widespread adoption of energy-saving technologies in production.…”

Development of an experimental facility for cooling circulated water of industrial plants

“…In the Republic of Uzbekistan, one of the main areas of the economy is currently receiving a lot of attention: the development of technological equipment for the energy industry that meets modern standards, such as the modernization of cooling systems for circulating water and air conditioning [1,2]. The 2017-2021 Strategy of Actions for the Further Development of the Republic of Uzbekistan emphasized the necessity of reducing the economy's energy and resource intensity through widespread use of energy-saving technologies [3][4][5][6].…”

“…The following tasks are set: to describe the structure of the layer at different operating modes of the apparatus, to determine the rates of the beginning of fluidization and the rate of carryover depending on the irrigation density L [11]. The intensification of air conditioning and cooling systems operation is one of the urgent problems in the practice of evaporative cooling of water [1,2]. Many developers have proposed a number of solutions for intensifying the cooling process based on this method.…”

Assessment of damage during the formation and passage of mudflows in the Tashkent region

“…Based on a digital map made on the Arc View 3.2 and ArcGIS 10 platforms, the most dangerous areas of mudflow manifestations were identified, and settlements located in the area of high mudflow activity were identified [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”
