Benefits of Ammonia in Refrigeration Systems in Pakistan and Globally

No comments

Refrigeration systems have evolved in the recent decades to enhance the effectiveness of cold stores and prefabricated houses. Since then, in Pakistan and many other countries, the use of natural refrigerants has become a norm or practice of many warehouses, cold stores, and supermarkets. This is where ammonia as a refrigerant is becoming a future-oriented choice for and cold stores in Pakistan.

A significant change in the use of refrigeration systems has been a result of changing regulatory regimes and related factors in the market. Moreover, preferences of consumers and societal elements have changed in the past few decades. In most Prefabricated houses in Pakistan, technologies are changing rapidly.

This is where the advantage of ammonia as a refrigerant has been widely embraced in the industry. That offers a wealth of benefits to industrial refrigeration.

Industrial Refrigeration with Glycol Ammonia as a Refrigeration System

Since the late 19th century, Ammonia has been utilized in the industry to meet the needs of refrigeration. Ammonia was introduced back in 1876; since the 1920s, other refrigerants such as CO2 and SO2 have also been used commonly to meet the needs of the industry. The benefits of ammonia as a refrigerant are widely embraced ever since.

Cold stores in Pakistan and advanced countries have evolved significantly. Let us first explore a little history of ammonia systems before discussing benefits in prefabricated houses.

A Little Peek into the History

Before discussing ammonia as a refrigerant benefit, let us discuss a little history.

When Chlorofluorocarbons (CFCs) was developed in the United States in the 1920. The pendulum was swung in the favor of other refrigerants such as Ammonia compared to all other ones. It is because CFCs were deemed to be the most harmless of all refrigerants and were considered extremely stable as chemicals.

However, back in the 19th century, scientists were not fully able to comprehend the consequences of using CFCs to the outer environment. Which is why, CFCs were considered as safe and their demand was increasing rapidly.

As CFCs became God-sent refrigerants for meeting needs, Ammonia was considered somewhat inferior to them and its users came under the pressure. Especially, in the large industrial installations and food preservations storages and warehouses, the harmful impacts of CFCs did not become visible.

In order to stop the depletion of Ozone layer in the environment, CFC refrigerants were finally considered harmful. Moreover, they were also contributing to global warming. In 1989, the Montreal protocol recommended all countries to stop usage of CFCs as refrigerants in cold rooms and prefabricated houses.

No wonder, cold stores in Pakistan and all its major cities are also preferring the use of ammonia as a refrigerant to suit the needs of the industry.

Benefits of Using Ammonia as a refrigerant in cold Stores and Cold Rooms

In the 20th century, the importance of Ammonia as a refrigerant skyrocketed as ammonia was considered as one of the most effective elements used in high and low temperatures. Here are the most important benefits of ammonia as a refrigerant in cold rooms in Pakistan.

Energy efficiency

Ammonia as a refrigerant is one of the most efficient applications out there to suit the needs of the industry. As mentioned, it was is suitable for both low and high range temperatures with an ever-increasing focus on energy saving. Industry experts and cold storage owners consider ammonia systems as the most safe and sustainable choices for the future.

In the recent years, there have been many developments in ammonia NH3 and carbon dioxide CO2 combination. This combination contributed to increase the efficiency of the industry. For instance, the combination of NH3 and CO2 has been extremely efficient for low and very low temperature applications below -40’C.

This seems like a perfect way to meet the requirements of cold stores and cold chains in Pakistan.

Environmentally-friendly

Another benefit of ammonia as a refrigerant is that it is considered as the most environmentally-friendly refrigerant to be used in prefabricated houses. The fact remains that ammonia belongs to the group of so-called “natural” refrigerants. This means that ammonia can have an impact on both GWP (Global Warming Potential) and ODP (Ozone Depletion Potential). If used effectively, it contributes to almost a zero percent increase in Ozone depletion. This makes ammonia as a refrigerant the most desirable choice for cold rooms and stores in Pakistan and globally.

Safety Benefits

Although ammonia is considered a toxic refrigerant and flammable in particular conditions. There is a need to handle it with care. This means that all the ammonia systems will have to be designed with an aim to promote safety instead of harm in cold stores and prefabricated houses.

In ordinary circumstances, ammonia as a refrigerant is unlike most other refrigerants in the industry. For example, it is a special odor that can be identified at even low concentrations. In case of minor leakages, experts can reduce its charge. This why, when use with CO2, this could be a most sought-after solution for the industry. Hence, for cold rooms and cold stores, ammonia is the safest refrigerant used in the industry.

Better Heat Transfer

The heat transfer properties are also considered superior in case of ammonia compared to most other chemical refrigerants. However, the best way to use ammonia is to allow   the use of equipment with a smaller heat transfer area. This way, the cost of the construction of plant will be lower. Moreover, ammonia can also help to reduce the operating cost of the system. This is a benefit to prefabricated houses in Pakistan.

 Conclusive Words

The current landscape surrounding cold stores and supermarkets is changing rapidly. Nowadays, food retailers, warehouse owners, and cold store designers prefer using ammonia as a first preference to meet their industrial refrigeration systems needs. With that said, ammonia as a refrigerant offers many benefits and factors need to be considered to increase its efficiency as a natural refrigerant.

In prefabricated houses, ammonia as a refrigerant will always be the future-oriented substance for meeting the needs of cold stores in Pakistan and refrigeration systems.
