An air conditioner is a system or a machine that treats air in a defined, usually enclosed area via a refrigeration cycle in which warm air is removed and replaced with cooler air. In construction, a complete system of heating, ventilation, and air conditioning is referred to as HVAC.
Condensers and evaporators are basically heat exchangers in which the refrigerant undergoes a phase change. Next to compressors, proper design and selection of condensers and evaporators is very important for satisfactory performance of any refrigeration system.

Design of Chiller for Air Conditioning of Residential Buildingijtsrd
Ā
The main objective of the project is to design and draft a fully functional Heating, Ventilation and Air Conditional HVAC system for computer center. From residential to commercial structures such as apartments, laboratories, hospitals, etc..., can be designed with HVAC components. HVAC is used to adjust the comfort level of both ambient temperature and air humidity to feel comfortable in enclosed spaces. As we want the heating, cooling, and ventilating system to perform well, we needed to start with an efficient duct design. In this project, we designed a duct system using the protocols based on ISHRAE Indian Society of Heating Refrigeration and Air conditioning Engineers and ASHRAE American Society of Heating Refrigeration and Air conditioning Engineers standards. The underlying principle was to design a duct system, which delivers the correct Cubic Feet per Minute CFM air flow to the residential building against the friction created by the ducts and fittings, with the static pressure available from the blower. When there is more surface area exposed to the air flow from the blower, amount of friction will increase and the blower must work more competently to achieve the required air flow. To provide greater air flow by overcoming the friction, radius elbow ducts are used, which provides smooth radius ensuring uniformity of air flow, reduces turbulence which in turn results in very low pressure drop. For Duct design calculations we used AUTO DESK REVIT design software. For space references and calculations, Autodesk Revit plan was taken from the civil department and the position of duct was identified. Based on the obtained Heat Load Calculations and cubic feet per minute are calculated by using E 20 form sheet and by using ISHRAE handbook, duct sizes were design and chiller size was estimated for residential building.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70Ā°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50Ā°C at 70Ā°C and between 4.83Ć10-07 at 9.04Ć10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
Micro RNA genes and their likely influence in rice (Oryza sativa L.) dynamic ...Open Access Research Paper
Ā
Micro RNAs (miRNAs) are small non-coding RNAs molecules having approximately 18-25 nucleotides, they are present in both plants and animals genomes. MiRNAs have diverse spatial expression patterns and regulate various developmental metabolisms, stress responses and other physiological processes. The dynamic gene expression playing major roles in phenotypic differences in organisms are believed to be controlled by miRNAs. Mutations in regions of regulatory factors, such as miRNA genes or transcription factors (TF) necessitated by dynamic environmental factors or pathogen infections, have tremendous effects on structure and expression of genes. The resultant novel gene products presents potential explanations for constant evolving desirable traits that have long been bred using conventional means, biotechnology or genetic engineering. Rice grain quality, yield, disease tolerance, climate-resilience and palatability properties are not exceptional to miRN Asmutations effects. There are new insights courtesy of high-throughput sequencing and improved proteomic techniques that organismsā complexity and adaptations are highly contributed by miRNAs containing regulatory networks. This article aims to expound on how rice miRNAs could be driving evolution of traits and highlight the latest miRNA research progress. Moreover, the review accentuates miRNAs grey areas to be addressed and gives recommendations for further studies.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
Ā
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

1. Different Types of Chiller
A chiller is a heat transfer device that uses refrigeration system to
remove heat from a process load and transfers the heat to the
environment. They are used to lower the temperatures of all kinds
of equipment and processes.
2. Water Chiller
Water cooled chillers are generally located within the building and
use cooling towers, a pond, or river located near the building to
reject waterās heat from the condenser. A water chiller is a
mechanical device used to facilitate heat exchange from water to a
refrigerant in a closed loop system.
3. Industrial Chiller
Industrial Chillers are normally used as part of a system to cool
Industrial Processes and large scale machinery. The Chillers work
by controlling the Cooling process, helping to regulate
temperatures at an optimum level, to prevent heat-generating
machinery from getting too hot. It is commenly used in
manufacturing industries such as food, beverage, packaging,
automotive etc.
4. Refrigeration Chiller
The refrigeration cycle starts with a low-pressure liquid/gas mix
entering the evaporator. It is based on the principle that a liquid
expanding into a gas extracts heat from the surrounding substance
or area. In which two different pressures exist in the cycle - the
evaporating or low pressure in the "low side," and the condensing,
or high pressure, in the "high sideā.
5. HVAC Chiller
HVAC water chillers play vital role in any HVAC systems along with
other basic components. New designs hvac chiller with better
efficiency and less operation and maintenance costs. An HVAC
chiller works on vapor compression.
7. Chiller Rentals
