Final Answer:

The correct liquid line temperature for an R-22 system operating with a liquid pressure of 226 psig and a specified subcooling of 5 degrees Fahrenheit is a) 115 degrees Fahrenheit

Step-by-step explanation:

To determine the liquid line temperature, we consider the saturation temperature and the specified subcooling. The saturation temperature corresponding to a liquid pressure of 226 psig for R-22 is 110 degrees Fahrenheit. Given that the specified subcooling is 5 degrees Fahrenheit, we add this to the saturation temperature:


\[110 + 5 = 115\]

Therefore, the liquid line temperature should be 115 degrees Fahrenheit. The closest match among the provided options is Option A (115 degrees Fahrenheit). This is the accurate and calculated liquid line temperature for the given R-22 system parameters.

The calculation involves understanding the relationship between pressure, temperature, and subcooling in refrigeration systems. In this case, subcooling is added to the saturation temperature to find the liquid line temperature, ensuring the system operates efficiently and reliably.
