Refrigeration cycle is a process in which refrigerant absorbs heat from a low-temperature space and rejects it in a high-temperature space.
Refrigerant absorbs heat from the low-temperature space (evaporator)
Refrigerant is compressed to increase its temperature and pressure
High-temperature refrigerant releases heat in the condenser
Refrigerant expands in the expansion valve to lower its temperature and pressure
Cycle repe
Various types of pumps with characteristics curves
Centrifugal pumps: high flow rates, low pressure, used in HVAC systems
Reciprocating pumps: high pressure, low flow rates, used in hydraulic systems
Diaphragm pumps: positive displacement, used for metering and dosing applications
Gear pumps: used for lubrication systems, constant flow rate
Axial flow pumps: high flow rates, low head, used in irrigation systems
The range of a cooling tower typically varies based on the size and capacity of the unit.
The range of a cooling tower can vary from small residential units to large industrial units.
Smaller cooling towers may have a range of a few tons of cooling capacity, while larger industrial cooling towers can have a range of hundreds or even thousands of tons.
The range of a cooling tower is typically measured in terms of cooling ...
Cooling towers are heat rejection devices that use water to transfer heat from a system into the atmosphere.
Cooling towers work on the principle of evaporation to remove heat from the water being circulated through the tower.
The hot water is pumped to the top of the tower and distributed over the fill or packing, where it is exposed to air.
As the water flows over the fill, some of it evaporates, which removes heat from...
Deaerator is placed at higher elevation to create a pressure difference for efficient removal of dissolved gases from feedwater.
Higher elevation creates a pressure difference which aids in the removal of dissolved gases from feedwater
This helps in preventing corrosion in the boiler system
It also improves the efficiency of the boiler by reducing the amount of oxygen in the feedwater
LP dosing refers to the process of injecting a low pressure chemical solution into a system or process.
LP dosing is commonly used in water treatment plants to add chemicals such as chlorine or coagulants to the water supply.
It is also used in industrial processes to introduce additives or inhibitors into pipelines or equipment.
LP dosing systems typically consist of a pump, piping, and injection point where the chemical...
Stroke length of a reciprocating compressor is the distance the piston travels from top dead center to bottom dead center.
Stroke length is an important parameter in determining the displacement volume of the compressor.
It is typically measured in inches or millimeters.
For example, a reciprocating compressor with a stroke length of 4 inches will have a piston that travels 4 inches up and down within the cylinder.
Stroke ...
Surging and choking are two common operating conditions in centrifugal compressors.
Surging occurs when the flow rate through the compressor is reduced to the point where the compressor cannot maintain a stable flow and pressure. This leads to a pulsating flow and can cause damage to the compressor.
Choking happens when the flow rate through the compressor is increased to the point where the compressor cannot handle the ...
