Working principle of piston compressor
When the crankshaft of the piston compressor rotates, the piston will reciprocate through the transmission of the connecting rod, and the working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will periodically change. When the piston of a piston compressor starts to move from the cylinder head, the working volume in the cylinder gradually increases. At this time, the gas flows along the intake pipe and pushes the intake valve to enter the cylinder until the working volume reaches the maximum. , The intake valve is closed; when the piston of the piston compressor moves in the reverse direction, the working volume in the cylinder is reduced, and the gas pressure is increased. When the pressure in the cylinder reaches and is slightly higher than the exhaust pressure, the exhaust valve opens and the gas is discharged from the cylinder , Until the piston moves to the limit position, the exhaust valve is closed. When the piston of the piston compressor moves in the reverse direction again, the above process repeats. In short, the crankshaft of a piston compressor rotates once, the piston reciprocates once, and the process of air intake, compression, and exhaust is realized in the cylinder, which completes a work cycle.
Advantages of piston compressor
1. The applicable pressure range of the piston compressor is wide, and the required pressure can be reached regardless of the flow rate;
2. The piston compressor has high thermal efficiency and low unit power consumption;
3. Strong adaptability, that is, a wide exhaust range, and is not affected by the pressure level, and can adapt to a wider pressure range and cooling capacity requirements;
4. Piston compressors have low requirements for materials, and use common steel materials, which is easier to process and lower in cost;
5. The piston compressor is relatively mature in technology, and has accumulated rich experience in production and use;
6. The device system of the piston compressor is relatively simple.
Note: In the unloading process, the compressor pressurizes the gas from the storage tank and then presses it into the tank car through the gas-phase pipeline, and presses the liquid from the tank car to the storage tank through the gas-phase differential pressure to complete the unloading process. When the gas phase is pressurized, the temperature of the gas phase will rise. At this time, forced cooling is not necessary, because if the gas phase is compressed and then cooled, it is easy to liquefy, and it is difficult to establish the pressure difference of the gas phase, which is not conducive to the replacement of the gas phase and the liquid phase. In short, it will cause the prolongation of the unloading process. If it is necessary to recover the residual gas, the cooler can be selected to forcibly cool the gas phase during the recovery operation, so as to recover the residual gas as soon as possible.The loading process is opposite to the unloading process.

How are air compressors used in refrigeration and HVAC systems?
Air compressors play a vital role in refrigeration and HVAC (Heating, Ventilation, and Air Conditioning) systems, providing the necessary compression of refrigerant gases and facilitating the heat transfer process. Here are the key ways in which air compressors are used in refrigeration and HVAC systems:
1. Refrigerant Compression:
In refrigeration systems, air compressors are used to compress the refrigerant gas, raising its pressure and temperature. This compressed gas then moves through the system, where it undergoes phase changes and heat exchange to enable cooling or heating. The compressor is the heart of the refrigeration cycle, as it pressurizes and circulates the refrigerant.
2. Refrigeration Cycle:
The compression of refrigerant gas by the air compressor is an essential step in the refrigeration cycle. After compression, the high-pressure, high-temperature gas flows to the condenser, where it releases heat and condenses into a liquid. The liquid refrigerant then passes through an expansion valve or device, which reduces its pressure and temperature. This low-pressure, low-temperature refrigerant then enters the evaporator, absorbing heat from the surrounding environment and evaporating back into a gas. The cycle continues as the gas returns to the compressor for re-compression.
3. HVAC Cooling and Heating:
In HVAC systems, air compressors are used to facilitate cooling and heating processes. The compressor compresses the refrigerant gas, which allows it to absorb heat from the indoor environment in the cooling mode. The compressed gas releases heat in the outdoor condenser unit and then circulates back to the compressor to repeat the cycle. In the heating mode, the compressor reverses the refrigeration cycle, absorbing heat from the outdoor air or ground source and transferring it indoors.
4. Air Conditioning:
Air compressors are an integral part of air conditioning systems, which are a subset of HVAC systems. Compressed refrigerant gases are used to cool and dehumidify the air in residential, commercial, and industrial buildings. The compressor pressurizes the refrigerant, initiating the cooling cycle that removes heat from the indoor air and releases it outside.
5. Compressor Types:
Refrigeration and HVAC systems utilize different types of air compressors. Reciprocating compressors, rotary screw compressors, and scroll compressors are commonly used in these applications. The selection of the compressor type depends on factors such as system size, capacity requirements, efficiency, and application-specific considerations.
6. Energy Efficiency:
Efficient operation of air compressors is crucial for refrigeration and HVAC systems. Energy-efficient compressors help minimize power consumption and reduce operating costs. Additionally, proper compressor sizing and system design contribute to the overall energy efficiency of refrigeration and HVAC systems.
By effectively compressing refrigerant gases and facilitating the heat transfer process, air compressors enable the cooling and heating functions in refrigeration and HVAC systems, ensuring comfortable indoor environments and efficient temperature control.
