Product Description
Using ammonia as a refrigerant has the following advantages:
1. Ammonia is the cheapest refrigerant besides air and water.
2. The standard boiling temperature is low, and the pressure is moderate in the condenser and evaporator.
3. A large refrigeration capacity per unit volume requires less refrigerant circulation per unit cooling capacity, high thermal conductivity, and high latent heat of vaporization.
4. Low throttling loss and high operating efficiency.
5. Low operating pressure, low requirements for machines, and low material cost for refrigeration systems.
6. There is a pungent odor, which is easily detected by the odor, leak test paper, and test drug in case of leakage. When the air contains 50mg/m3 of ammonia, the human sense of smell can distinguish it.
7. Insoluble with mineral oil, easily separated from oil at low temperatures, ammonia has a lower density than oil, and refrigeration oil often sinks below the ammonia liquid, making it convenient to return oil to the refrigeration system.
8. Thermodynamic and chemical properties are stable at room temperature and low temperature.
9. ODP=0, GWP=0.
The amount of ammonia filling in the system is closely related to the possibility of danger. In system design, measures such as optimizing the system, using plate heat exchangers and dry shell evaporators, using nitrogen direct expansion supply, and using NH3/CO2 cascade refrigeration cycles can significantly reduce the amount of refrigerant filling. In addition, a large ammonia refrigeration system simplified by using direct expansion supply and lubricating oil that is miscible with ammonia will greatly reduce the amount of ammonia used due to system simplification.
Using high-efficiency air coolers to reduce the amount of ammonia stored in the cold room. The current international trend in the development of ammonia systems is to reduce the amount of ammonia injected into the system and choose efficient and energy-saving air coolers. The high-efficiency variable pitch stainless steel coil air cooler can be used as the evaporator in the warehouse, which only accounts for 5% of the traditional smooth discharge pipe ammonia injection amount at the same cooling capacity, reducing the ammonia injection amount by 95%.
The design of ammonia refrigeration system should adopt automatic control as much as possible to reduce leakage and ensure the safety of operators.

What Are the Key Components of a Screw Compressor?
A screw compressor consists of several key components that work together to compress air or gas. Here’s a detailed explanation of these components:
1. Male and Female Rotors:
The male and female rotors are the primary components of a screw compressor. These helical rotors have specially designed profiles that interlock with each other. The male rotor typically has fewer lobes or threads compared to the female rotor. As the rotors rotate, the interlocking lobes create compression chambers that gradually reduce in volume, compressing the air or gas.
2. Compression Chamber:
The compression chamber is formed by the interlocking lobes of the rotors. It is the space where the air or gas is compressed as the rotors rotate. The volume of the compression chamber decreases as the lobes move towards the discharge end, resulting in the compression of the trapped air or gas.
3. Inlet and Outlet Ports:
The inlet port is the entry point through which the air or gas enters the screw compressor. It is typically located at the suction side of the compressor. The inlet port allows the air or gas to flow into the compression chamber during the suction process. The outlet port is the exit point through which the compressed air or gas is discharged from the compressor.
4. Drive System:
The drive system of a screw compressor consists of a motor and a drive mechanism. The motor provides the rotational power required to drive the rotors. Common types of drive mechanisms include direct drive, belt drive, and gear drive. The drive system ensures that the rotors rotate in opposite directions at the desired speed and synchronization.
5. Oil System (in oil-injected compressors):
In oil-injected screw compressors, an oil system is present to provide lubrication, cooling, and sealing between the rotors. The oil system typically includes an oil reservoir, an oil pump, oil filters, and oil coolers. The lubricating oil is injected into the compression chamber, where it forms a thin film on the rotors, reducing friction and minimizing wear.
6. Cooling System:
Screw compressors often incorporate a cooling system to maintain optimal operating temperatures. The cooling system may include air or water-cooled heat exchangers, which dissipate the heat generated during compression. Cooling ensures that the compressor operates within safe temperature limits, preventing overheating and prolonging the lifespan of the components.
7. Control System:
A control system is an essential component of a screw compressor, providing monitoring and regulation of various parameters. It may include sensors, controllers, and safety devices to measure and control variables such as pressure, temperature, and operating conditions. The control system ensures efficient and safe operation of the screw compressor.
8. Sound Attenuation and Vibration Isolation:
To reduce noise and vibration, screw compressors are often equipped with sound attenuation measures and vibration isolation systems. These components help in minimizing the noise and vibrations generated during operation, making the compressor suitable for noise-sensitive environments.
In summary, the key components of a screw compressor include the male and female rotors, compression chamber, inlet and outlet ports, drive system, oil system (in oil-injected compressors), cooling system, control system, and sound attenuation/vibration isolation components. These components work together to enable the efficient compression of air or gas in the screw compressor.
