What is Hand-Operated Expansion Valve? A hand-operated expansion valve refers to a type of expansion valve that can be manually controlled or adjusted by hand. Expansion valves are crucial components in refrigeration and air conditioning systems, regulating the flow of refrigerant into the evaporator coil. The hand-operated aspect allows for manual adjustment of the valve …
What is Hydrocarbon Refrigerant? A hydrocarbon refrigerant is a type of natural refrigerant that consists of compounds made up of hydrogen (H) and carbon (C) atoms. Hydrocarbon refrigerants are organic compounds that belong to the broader category of natural refrigerants, which also includes substances like ammonia (NH3), carbon dioxide (CO2), and water (H2O). Hydrocarbon refrigerants …

What is Compound Vapour Compression Refrigeration System? A compound vapor compression refrigeration system is an advanced configuration of the traditional vapor compression refrigeration system. It involves multiple stages of compression and expansion, often utilizing multiple compressors and evaporators, to achieve improved performance, higher efficiency, and the ability to handle a broader range of operating conditions. …
What is Induced Draft Cooling Towers? Induced draft cooling towers are a type of cooling tower that operates on the principle of creating a negative pressure or draft within the tower, drawing air through the structure. Unlike forced draft cooling towers, induced draft towers have mechanical fans located at the tower’s exhaust or discharge section, …
What is Refrigerant Compressors? Refrigerant compressors are essential components in refrigeration and air conditioning systems. Their primary function is to compress and circulate the refrigerant gas within the system, allowing it to undergo a phase change from a low-pressure, low-temperature gas to a high-pressure, high-temperature gas. This process is crucial for the overall refrigeration cycle, …

What is Mechanical Draft Cooling Tower? A mechanical draft cooling tower is a specialized heat rejection device used in industrial processes and power generation to dissipate excess heat from water systems. Unlike natural draft cooling towers, which rely on the natural buoyancy of warm air for convection, mechanical draft towers actively use mechanical fans to …
What is Capillary Tube? A capillary tube is a narrow, thin-walled tube used in refrigeration and air conditioning systems as a metering device to control the flow of refrigerant from the high-pressure side (condenser) to the low-pressure side (evaporator). It is a simple and cost-effective component that serves as an alternative to more sophisticated expansion …
