Pump Construction (Part1)
In 1689 the physicist Denis Papin invented the centrifugal pump and today this kind of pump is the most used around the world. The centrifugal pump is built on a simple principle: Liquid is led to the impeller hub and by means of the centrifugal force it is flung towards the periphery of the impellers. The construction is fairly inexpensive, robust and simple and its high speed makes it possible to connect the pump directly to an asynchronous motor.
Expansion Valves Selection
The expansion valve regulates the amount of compressed liquid refrigerant moving into the evaporator. It removes pressure from the liquid refrigerant to allow expansion or change of state from a liquid to a gas in the evaporator. In order to properly select Expansion Valves one should pay attention to the items that we mention in this post.
जल ट्यूब बनाम अग्नि ट्यूब बॉयलर
वॉटर ट्यूब बॉयलर और फायर ट्यूब बॉयलर दो अलग-अलग प्रकार के स्टीम बॉयलर हैं जो आमतौर पर औद्योगिक और वाणिज्यिक अनुप्रयोगों में उपयोग किए जाते हैं। दोनों प्रकार के बॉयलर भाप उत्पन्न करने के लिए ट्यूबों की एक प्रणाली का उपयोग करते हैं, लेकिन वे ट्यूबों की व्यवस्था के तरीके और बर्नर से गर्म गैसों के ट्यूबों से गुजरने के तरीके में भिन्न होते हैं।
जल हथौड़ा (भाग 1)
Under unfavorable circumstances, damage due to water hammer may occur in pipelines measuring more than one hundred meters and conveying only several tenths of a liter per second. But even very short, unsupported pipelines in pumping stations can be damaged by resonant vibrations if they are not properly anchored. By contrast, the phenomenon is not very common in building services systems, e.g. in heating and drinking water supply pipelines, which typically are short in length and have a small cross-section.
प्रशीतन सूत्र और गणना
These formulas are commonly used in the field of refrigeration and air conditioning to calculate various performance parameters of a refrigeration system such as compression work, compression power, coefficient of performance, net refrigeration effect, capacity, compressor displacement, heat of compression, volumetric efficiency, and compression ratio. These formulas are based on the thermodynamics principles and are generally used to evaluate the performance of the refrigeration system and to optimize its design.
वेग का गुणांक (Cv)
Cv, or coefficient of velocity, is a measure of the flow capacity of a valve. It represents the number of gallons per minute (GPM) of water at 60°F that will flow through a valve with a one-inch opening at a pressure drop of one pound per square inch (PSI). Cv can be calculated using various formulas, such as the one based on water at 60F and one that takes into account the specific gravity of the fluid. Cv is a theoretical value and it may vary depending on the actual conditions of the valve. When selecting a valve for a specific application, it is important to consider the Cv in relation to the flow rate and pressure drop requirements of the system, as well as other factors such as ease of maintenance, cost, and safety.
पाइप इन्सुलेशन दिशानिर्देश
ऊर्जा दक्षता, तापमान नियंत्रण, संक्षेपण नियंत्रण, शोर में कमी और सुरक्षा बनाए रखने के लिए पाइप इन्सुलेशन महत्वपूर्ण है। ASHRAE अपने मानक 90.1 में विभिन्न पाइप आकारों और तापमान सीमाओं के लिए विशिष्ट मोटाई की सिफारिशें प्रदान करता है। ASHRAE मानकों के आधार पर पाइप इन्सुलेशन का चयन करते समय, तापमान, पाइप आकार, पर्यावरणीय विचार, अग्नि प्रतिरोध और ऊर्जा दक्षता पर विचार करना महत्वपूर्ण है।

In this post, we will be continuing our comprehensive training on how to size refrigerant piping. We will cover all the important aspects of this process, including determining the pipe size, pressure drop, and other factors. We will also discuss topics such as sizing refrigerant lines, equivalent length for refrigerant lines, and how to determine equivalent length. With this training, you will have the knowledge and confidence to size refrigerant piping accurately and correctly in any situation.
