What is the difference between ammonia clock and caesium clock?

An ammonia clock measures time based on the frequency of microwave radiation absorbed by ammonia molecules, while a caesium clock measures time based on the vibrations of caesium atoms. Caesium clocks are more accurate and stable compared to ammonia clocks, making them the standard for defining the international unit of time, the second.


How does a ammonia purger work?

An ammonia purger removes air and noncondensables from the ammonia system by directing vapor from the condenser, where air collects, through cold liquid ammonia. This condenses the ammonia and separates noncondensables which are then removed from the system.


How do ammonia absorption refrigerators work to cool food and beverages efficiently?

Ammonia absorption refrigerators work by using a combination of ammonia, water, and hydrogen gas to create a cooling effect. The process starts with ammonia evaporating in one part of the system, absorbing heat and cooling the surrounding area. The ammonia gas then travels to another part of the system where it is absorbed by water, releasing the heat and returning to a liquid state. This cycle continues, with the ammonia gas being absorbed and released, creating a continuous cooling effect that efficiently cools food and beverages.


How does a anhydrous ammonia refrigeration system work?

An anhydrous ammonia refrigeration system works by circulating ammonia gas through a closed loop system of pipes. The ammonia gas is compressed into a liquid state, which absorbs heat from the environment as it evaporates back into a gas. This process cools the space or equipment it is designed to refrigerate.
