What is the maximum allowable leakage rate for stationary refrigeration systems?

The maximum allowable leakage rate for stationary refrigeration systems being typically less than 5% per year is grounded in regulatory guidelines that aim to minimize the environmental impact of refrigerants. This standard reflects a balance between operational efficiency and environmental responsibility.

Systems with a leakage rate of less than 5% per year indicate reasonable performance, ensuring that refrigerants are not excessively escaping into the atmosphere. This threshold is also essential for maintaining the effectiveness of refrigeration systems and ensuring compliance with regulations regarding greenhouse gas emissions.

Maintaining leakage rates above this threshold can lead to significant refrigerant loss, contributing to global warming and other environmental issues. Therefore, targeting a leakage rate below 5% helps in promoting sustainable practices within the refrigeration industry. The options indicating higher rates, such as up to 10% or between 2-3%, do not align with these regulations and objectives, thereby reinforcing the importance of striving for lower leakage rates in stationary refrigeration systems.
