1. What is the Actual Volume of Refrigerant?

The actual volume of refrigerant (V_s) is the volume occupied by the refrigerant in the compressor during the suction stroke. It represents the actual amount of refrigerant that the compressor handles per cycle.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V_s \) — Actual volume of refrigerant (m³)
• \( \eta_v \) — Volumetric efficiency of compressor (unitless)
• \( V_p \) — Stroke volume of compressor (m³)

Explanation: The formula calculates the actual volume of refrigerant by multiplying the volumetric efficiency with the stroke volume of the compressor.

3. Importance of Actual Volume Calculation

Details: Accurate calculation of the actual volume of refrigerant is crucial for determining compressor performance, system efficiency, and proper refrigerant charge in refrigeration and air conditioning systems.

4. Using the Calculator

Tips: Enter volumetric efficiency (between 0 and 1) and stroke volume in m³. Both values must be valid (η_v ≥ 0, V_p > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is volumetric efficiency?
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: What factors affect volumetric efficiency?
A: Factors include compressor design, operating conditions, refrigerant properties, and system pressure ratios.

Q3: What is typical range for volumetric efficiency?
A: Volumetric efficiency typically ranges from 0.6 to 0.9 for most refrigeration compressors under normal operating conditions.

Q4: Why is stroke volume important?
A: Stroke volume represents the maximum displacement capacity of the compressor and serves as the basis for calculating actual refrigerant flow.

Q5: How does this calculation help in system design?
A: This calculation helps determine the actual refrigerant mass flow rate, which is essential for sizing system components and evaluating system performance.
