ammonia is used as a cooling agent mainly because it easily transfers heat.In addition to this there are several reasons why ammonia is used as a cooling agent in refrigerators.
Urea, a compound found in urine, has antimicrobial properties and can act as a mild cleaning agent. It has been used historically in some cultures for cleaning purposes.
Ammonia is considered an oxidizer, particularly in fertilizer. The oxidation of the ammonia produces nitric acid. Adding chlorine to ammonia increases the oxidizing capabilities, but is also extremely dangerous.
Sulfuric acid (H2SO4) is commonly used as a drying agent for ammonia gas. It reacts with ammonia to form ammonium sulfate and helps to remove moisture from the gas.
It is regular old ammonia -- NH3. "Ammonia-D" is a trademarked name for ammonia in Windex.
Ammonia is a reducing agent because it can donate electrons to other substances. It has a lone pair of electrons on the nitrogen atom that can be used in redox reactions, where it reduces another substance by transferring its electrons to it. This ability to donate electrons makes ammonia a strong reducing agent in certain reactions.

CFC's are mainly there in refrigerators only. They act as cooling agent i.e. they perform the main work.

Refrigerators use a refrigerant as a cooling material to absorb heat from the inside of the refrigerator and release it outside. Common refrigerants used in refrigerators include hydrofluorocarbons (HFCs) and hydrochlorofluorocarbons (HCFCs).

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.
A Dometic fridge typically uses ammonia gas as the cooling agent in its absorption refrigeration system. This gas is circulated through the fridge's coils to help cool the interior and maintain a cold temperature.
The common name for NH3 is ammonia. Ammonia is often used as a household cleaning agent in a solution of ammonium hydroxide.
RV refrigerators do not use freon but rather ammonia. The ammonia is in a sealed unit called the cooling unit and you cannot add ammonia to this unit. If it goes bad it has to be replaced.
