There are several low-cost options to increase the compressor capacity, including the following: Install a large diameter main fractionator overhead vapor line, or parallel line, if the pressure drop across this line is more than 0.5 psi (0.034 bar). Welch, in Refrigeration, Air Conditioning and Heat Pumps (Fifth Edition), 2016. Infinite capacity reduction from 100% to 10% (RWF II) or 25% (RXF) of full load is provided by a slide valve control—one of the most efficient methods of capacity control for screw compressors. As shown in Figure 9, the power almost decreased linearly with capacity. Power consumption and capacities are propotional speed. The refrigeration capacity of a compressor is the product of the evaporator enthalpy rise and the compressor mass flow rate. The primary control methods are external recycle and unloaders, which either hold open the suction valves or add clearance volume to the cylinder. It is because that the compression processisassumedasan adiabatic process in theoretical model, but in actual situation, the compressionprocessisa polytropic process. 4. 0.0 ˚C Model UP/UX150 Displacement 146 cc/rev Cylinders 10 Max speed 4500 rpm. From the diagrams, it can be found that the pressure pulsation in discharge stroke can not be found in suction stroke, which could be explained that suction valves are held steady by hydraulic actuators in suction stroke. Motor-driven reciprocating compressors above 75 kW in size are usually equipped with a step control. This is generally accomplished by throttling the discharge valve. Constant speed characteristics of various types of compressors. h = h lc - h ec (7) where . However, large low-speed machines are generally driven by large synchronous motors at fixed speeds. It may seem that speed control would be the logical control method for reciprocating compressors. The results are shown in Figure 8. Theoretical and experimental study on stepless capacity control system of reciprocating compressor, 7th International Conference on Compressors and their Systems 2011, Based on the theoretical models mentioned above, the pressure in cylinder in situations of different, Dynamic characteristics of rolling piston machines.

The design of the pulsation dampening equipment is based on acoustical analog evaluation which takes into account the specified operating speed range, conditions of unloading, and variations in gas composition. Generalized compressor control methods, Saeid Mokhatab, William A. Poe, in Handbook of Natural Gas Transmission and Processing, 2012, The compressor capacity is a critical component in determining the suitability of a particular compressor. Xie, in 7th International Conference on Compressors and their Systems 2011, 2011. Fig 9. And the compressor capacity is zero in this situation. The importance of this is obvious when one remembers that while a tool or appliance may use a considerable amount of air, it is only working intermittently, whereas any leakage, even from a small hole, is both continuous and significant. Reciprocating compressor capacity calculation formula. The importance of this is obvious when one remembers that while a tool or appliance may use a considerable amount of air, it is only working intermittently, whereas any leakage, even from a small hole, is both continuous and significant. Around 3% and 5% increase in volumetric efficiency and COP, respectively, can be achieved with the optimized design. Cut away view of small commercial six-cylinder compressor (Bitzer). Pulsation is inherent in reciprocating compressors because suction and discharge valves are open during only part of the stroke. It is defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours. Compressor capacity-control methods are utilized to maintain a required delivery under variable process conditions. We use cookies to help provide and enhance our service and tailor content and ads. When the effective compression stroke length Sc is 0.02m, the capacity reaches to zero exactly, and this is called zero capacity point. The design variables to be optimized are the cylinder radius, the rotor radius, the shaft radius, the eccentric radius, the vane thickness and the spring constant. Based on the theoretical models mentioned above, the pressure in cylinder in situations of different compressor capacity has been calculated by changing the duration of reverse flow stroke, and theoretical p-V diagrams of compressor operation cycle that are compose of the calculated data of each stroke were plotted.
