The stroke volume of compressor is the displacement volume of the piston, between the top dead center and the bottom dead center of the compressor. It represents the theoretical maximum volume that the compressor can handle per cycle.
The calculator uses the formula:
Where:
Explanation: This formula calculates the theoretical displacement volume of the compressor based on the actual volume of refrigerant handled and the compressor's volumetric efficiency.
Details: Accurate stroke volume calculation is crucial for compressor sizing, performance evaluation, and system design in refrigeration and air conditioning applications.
Tips: Enter actual volume of refrigerant in m³ and volumetric efficiency as a decimal between 0 and 1. Both values must be positive numbers with volumetric efficiency not exceeding 1.
Q1: What is volumetric efficiency in compressors?
A: Volumetric efficiency is the ratio of the actual volume of refrigerant passing through the compressor per cycle to the stroke volume of the compressor.
Q2: Why is stroke volume important in compressor design?
A: Stroke volume determines the compressor's capacity and helps in selecting the right compressor size for specific refrigeration requirements.
Q3: What factors affect volumetric efficiency?
A: Factors include clearance volume, pressure ratios, valve design, gas properties, and operating conditions.
Q4: How does stroke volume relate to compressor performance?
A: Larger stroke volumes generally indicate higher compressor capacity, but efficiency must be considered for optimal performance.
Q5: Can this calculation be used for all compressor types?
A: This formula is primarily applicable to reciprocating compressors where piston displacement is a key parameter.
