Nigeria is an African country with a population of over 200 million, making it the largest country in Africa by population. With such a large population, temperatures over much of the country reach very high levels.
This is why it is important to have access to cooling technology such as refrigeration and air conditioning, in order to keep homes and offices cool. Refrigeration is the process of cooling air or food by removing both heat and moisture.
Although the country has very limited access to refrigeration and air conditioning, it is essential for the welfare of its citizens.
Refrigerant gases serve many purposes when it comes to keeping a space cool. We can use them to refrigerate our food, to keep indoor climate controlled and to cool down electronics and electrical components. Even with efficient and effective refrigerants, refrigeration is an energy intensive process, which means it can be costly to implement.
However, the benefits that come from using renewable energy to power a refrigeration system far outweigh the costs, as renewable energy helps reduce emissions, improve air quality and reduce energy costs.
In Nigeria, there is an urgent need for high-efficiency refrigerant systems that use a wide variety of renewable energy sources. This is why in recent years, the country has begun to invest in renewable energy projects in order to make these refrigeration systems more accessible.
For instance, Nigeria signed an agreement to build a 50MW solar PV plant and a 10MW wind plant.
The importance of effective refrigeration cannot be overstated. It is essential to food safety, energy efficiency, and human health as it helps reduce the spread of diseases via food spoilage. It also helps reduce the level of indoor air pollution.
This is why for many African countries, the introduction of advanced refrigerants is extremely important. Not only can they provide a much-needed cooling effect to Nigerians, but they also help reduce the amount of pollutants released into the air.
This is why Nigerians are increasingly turning to advanced refrigerants in order to meet their cooling needs.
The NIgeria refrigerant market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The system produces solar-powered freezers that rely more on solar energy than on public power to power the devices.
They claimed that Koolboks provides an inexpensive off-grid solution that can produce refrigeration continuously for up to four days—even in the event of a power outage or low sunlight.
The refrigerant-charged integrated solar water heater’s thermal performance was examined to demonstrate its suitability for use in Nigeria. This unit was built and tested side by side and contains three identical small-scale solar water heating systems that use ethanol, R-134a, and R12 as refrigerants.
About 14:00 hours were needed to reach the maximum water temperature increases of 28°C, 37°C, and 40°C for R12, ethanol, and R-134a, respectively. The maximum collection efficiencies calculated were 40.63%, 50.78%, and 56.59% for R12, ethanol, and R-134a, respectively.
R134a provided the best results, most likely as a result of its increased liquid thermal conductivity, higher latent heat, and improved capillary pumping through lower viscosity and higher surface tension.
