What Is The Performance Of Ammonia Evaporator?
Jan 19, 2018

Liquid ammonia is liquefied ammonia, also known as anhydrous ammonia, is a colorless liquid, corrosive, and easily volatile. It is formed when gaseous ammonia is pressurized to 0.7 ~ 0.8MPa, and emits a large amount of heat at the same time. In contrast, liquid ammonia evaporates to absorb a large amount of heat. Because of its good thermodynamic properties, liquid ammonia is widely used as a refrigerant in refrigeration systems.


The evaporator of the direct evaporative cooling system is replaced by the condensing evaporator, the refrigerant of the direct evaporating system absorbs the heat of the refrigerant through the condensing evaporator, and the temperature of the carrier gas decreases; the carrier of the cryogenic refrigerant enters the accumulator and is pumped by the pump to the evaporator, after the heat absorption temperature, re-enter the condensing evaporator, for the cooling process


Ammonia, as a green natural refrigerant, has zero ozone depletion potential (ODP) and zero global warming potential (GWP). Due to its good thermodynamic properties and its absence of any adverse effects on the atmosphere, it is inexpensive and is used in about 80% of the world's largest cold storage facilities


In the course of special treatment, the environmental problems caused by the simplification of "replacing Freon with ammonia" should be strictly avoided. Scientific performance and safety should be fully demonstrated through scientific technical, focusing on improving ammonia-related refrigeration technology, management, and promote the health-related development of ammonia-related refrigeration enterprises.
