Industrial refrigeration Melbourne has become increasingly commonplace in the last few decades. The reason is simple: the city’s industrialisation has created a demand for a more efficient and cost-effective solution to air conditioning and refrigeration systems. However, while the equipment for such use has evolved dramatically, the basic principles of refrigeration remain the same. Fortunately, some excellent solutions are out there to help your business keep its products and processes cool and dry.
Ammonia
Anhydrous ammonia is used in industrial refrigeration in Australia, and it is a colourless gas with a pungent odour, and ammonia is a naturally occurring compound composed of one part nitrogen and three parts hydrogen.
In large-scale refrigeration systems, ammonia is used because of its excellent thermodynamic properties. These properties enable ammonia to achieve higher efficiency than most synthetic refrigerants. Also, ammonia does not damage the ozone layer.
When working with ammonia, be sure to follow all of the safety guidelines and have a plan for dealing with any leaks. Often, a minor leak can be easily detected and investigated and help avoid more severe complications.
Liquid adsorbent
An adsorption refrigeration system is a promising solution for many heating applications. Adsorption chillers can use water as a refrigerant, producing hydrogen as an end product. However, their lifespan is short, and maintenance needs to be regular.
The adsorbent material can be natural or synthetic, and activated carbon is one of the most common adsorbent materials. It has a large surface area and is highly porous.
Choosing an appropriate adsorbent can lead to a more efficient refrigerant uptake. Other factors to consider include pore distribution and chemical properties. Several types of adsorbents are used for industrial refrigeration Melbourne.
One of the most popular adsorbent/refrigerant pairs is zeolite/water. Another type of adsorbent/refrigerant pair is activated carbon/methanol. Besides adsorbents, other materials are added to enhance their performance. These include metal-organic frameworks (MOFs).
Metal-organic frameworks have attractive adsorption characteristics. They also offer high stability. Moreover, they are less susceptible to contamination.
Carbon dioxide
Carbon Dioxide is a naturally occurring gas that can absorb and store heat. It makes it an excellent refrigerant for heat recovery applications.
It is an effective alternative to ammonia and glycol. The advantages of using CO2 are its low Global Warming Potential (GWP) and its non-toxicity. Also, it has low moisture content.
In some industrial refrigeration Melbourne systems, the volumetric efficiency of carbon dioxide is four to twelve times greater than ammonia. However, this is not the case in all cases.
Although CO2 offers many advantages, it is essential to note that it is not suitable for all applications. Therefore, it is necessary to design the system correctly and ensure that the equipment can withstand the industrial environment.
Hydrocarbons
Hydrocarbons are a class of refrigerants that are a natural product of nature. They are made up of hydrogen and carbon atoms. They occur naturally in crude oil and are used in refrigeration and heating applications.
The most common hydrocarbons are propane (R-290) and isobutane (R600a). These are the most widely used in commercial refrigeration and air conditioning systems.
Hydrocarbons offer excellent energy efficiency, resulting in lower energy costs. They can be installed in small and medium-sized systems. Because they are non-toxic, they are an environmentally friendly alternative to CFCs.
Safety is another critical factor. There are flammability restrictions for these refrigerants, so proper training is essential. It is also necessary to follow local and international safety standards to control the risk of explosion.
Fluorocarbons
The refrigeration and air conditioning industry has become more complex over the years. With growing needs from users throughout the economy, it has become necessary to innovate to meet the challenges of today. It includes the use of alternative refrigerants. Hydrocarbons, in particular, have proved to be an adequate replacement for harmful fluorocarbons. These are cheap byproducts of oil and gas and are compatible with other components in many existing systems.
A recent study suggests that 99% of domestic refrigeration models use hydrocarbons. Hydrocarbons are cost-effective and have the thermodynamic advantages of a lower condensing point and more efficient COP. Combined with their lower CO2 emissions, these positively impact the environment.
Preparation counters
Preparation counters, also known as catering prep stations, are necessary for any commercial kitchen. They are designed to be robust and durable and withstand the day-to-day pressures of demanding catering environments.
There are many different types of preparation counters. The fridge, freezer and display options are all available, but which is suitable for you?
Refrigerated prep counters are ideal for quick food prep in a commercial kitchen. These units provide a large work surface, refrigerated storage, and built-in chopping boards.
Food prep counters can be an excellent addition to any business looking to add something extra to their point of sale. Typically they feature a granite or granite-like surface, which prevents the dough from sticking.
