How can the capacity of an ammonia receiver be affected by temperature?

The capacity of an ammonia receiver is significantly influenced by temperature, primarily due to the properties of gases and the principles of thermodynamics. As temperature increases, the vapor pressure of ammonia also rises. This phenomenon typically results in a reduction in the capacity of the receiver to hold liquid ammonia. Consequently, the higher the temperature, the greater the amount of ammonia that will vaporize, leading to a situation where the liquid ammonia that can be stored is decreased.

This is crucial for operational efficiency, especially in applications where ammonia is used as a refrigerant. Understanding the relationship between temperature and capacity helps in designing systems that maintain optimal conditions for ammonia storage, ensuring safety and effectiveness in refrigeration processes. Thus, a rise in temperature will indeed lead to a reduced capacity in the ammonia receiver, validating the choice that higher temperatures decrease capacity.
