What are Refrigeration Systems

A refrigeration system is a mechanism that helps lower the temperature of a specific area. This lowering of temperature prevents spoilage of products such as medicine & food. The purpose of the refrigeration system in cold storage is to maintain precise temperatures. 

It helps to keep products and goods fresh. The system works by allowing the refrigerant to circulate through various components, from a condenser and compressor to an evaporator. They together absorb and release heat to lower the temperature.

A precise consideration is important while choosing a refrigeration system for your cold storage. Their energy efficiency and available temperature ranges, along with their environmental impact, are some important points to consider. 

These factors create a powerful effect on your decision-making process. We’ll discuss various types of refrigeration systems and important factors here that help you choose the right one.

Types of Refrigeration Systems for Cold Storage

Every refrigeration system comes with its advantages. Which type suits different cold storage requirements best? We will find out by looking at the main types.

Vapor Compression Systems

It is the most common refrigeration system in cold storage. Vapor compression systems are highly efficient and flexible in controlling both low and medium-low temperatures.

How It Works

1. Compressors at the first spot compress the refrigerant. It raises its temperature and pressure.
2. The condenser does the second step. It releases the trapped heat from refrigerant into the surrounding environment.
3. The expansion valve is responsible for lowering the pressure of the refrigerant. The purpose is to cool it down.
4. The evaporator helps to absorb the heat from the cold storage area. 

Vapor compression systems are mostly common and are perfect for supermarkets, warehouses, and small-scale cold storage.

Absorption Refrigeration Systems

These refrigeration systems work on an absorption mechanism that requires heat rather than electricity. People prefer it in areas where the energy supply is expensive and not reliable. These systems need an absorbent in the equipment to absorb the refrigerant vapor. The most used absorbents are water and lithium bromide. 

Benefits:

1. It can run on various alternative energy sources, from steam and natural gas to solar power. 
2. Designed for use in remote sites lacking reliable electricity.

Cascade Refrigeration Systems

This refrigeration system is best for achieving ultra-low temperatures in cold storage stores for pharmaceutical or scientific research. It has various stages to cool down the refrigerant further. 

How It Works

1. One refrigeration cycle helps to cool down the refrigerant for another cycle. It further lowers the temperature.
2. This system is specifically helpful in cold storage facilities that require temperatures below -50°C.

CO₂ Refrigeration Systems

CO₂ is an eco-friendly refrigerant with a low global warming potential (GWP). It is commonly known as carbon dioxide. They offer environmental benefits and excellent energy efficiency, which is why these refrigerant systems are becoming increasingly popular. 

Why Choose CO₂?

1. CO₂ refrigerant is helpful because it reduces carbon emissions and complies with environmental regulations. 
2. It is also effective in warmer climates due to its ability to work efficiently at high pressures.

Ammonia Refrigeration Systems

Ammonia or NH₃ is a highly efficient refrigerant, which is why it is best for industrial refrigeration setups. These systems are cost-effective and can provide higher cooling capacity as compared to other refrigerants.

Drawbacks:

1. What makes it unsuitable is it requires careful handling due to ammonia’s toxic and flammable nature. 
2. It is most suitable for large-scale operations, including food processing plants or large warehouses. 

Choose The Refrigeration System Wisely

Keenly check and then pick the refrigeration system to make your cold storage unit operation successful. Before selecting the refrigeration system for your cold storage units, the following factors need your attention. 

Require Temperature

The first thing you understand and record is the temperature range required to store your goods. The optimal cold storage temperatures typically fall into one of the following categories:

• 0°C to 5°C is chilled storage, which is the perfect temperature for fruits, vegetables, dairy, etc.
• -18°C to -25°C is frozen storage. It works best for meats, frozen foods, etc.
• Below -50°C is an ultra-low temperature. This is suitable for pharmaceuticals and sensitive biological products.

It is important to know the optimal temperature requirements. It helps you to choose a refrigeration system with the right specifications.

Energy Efficiency

Energy consumption costs too much in cold storage operations. The rate gets high because refrigeration systems continuously run. To keep the prices lower, one should pick an energy-efficient refrigeration system, which helps lower operational costs. Some points to check are

1. It is important to look for a system with high Coefficient of Performance or COP ratings.
