Glycol Chillers Working Principle
Glycol Chillers Glycol chillers are one of the many refrigeration systems we can currently find in the market. As the name suggests, this type of chillers base their operation in the use of glycol. But before we learn how they work, let’s understand why glycol. What is glycol? Glycol is a translucid and slightly thick chemical compound [...]
Constant Force Springs Design and Applications
Constant force spring, as the name implies, is used to refer a spring that experience and exhibits near-constant force over its range of motion. The concept behind constant force springs stems from metal strips that have undergone a series of changes. Which in return create tension in the metal strips, enabling them to execute [...]
Working Principles of Vapour Absorption Refrigerant System
Vapor absorption refrigeration is suitable where an inexpensive source of heat energy is easily available. In these cases using the heat directly as the operating energy is the common practice. The powerplants where heat from the co-generation process is available can use VARS. Steam turbine power plants can use the waste heat [...]

What is Draft Tube ? Describe its Functions and Classifications
In hydraulic turbines, the component draft tube is very significant. In impulse turbines, the flow energy of the fluid is converted to kinetic energy by means of the nozzle. In Reaction Turbines, part of the flow energy is converted to K.E but remaining energy is still the pressure energy. Draft tubes are used in Reaction turbines to [...]
