How Does Refrigeration Work?Leave a Comment
Most manufacturers are accustomed to using CFC-based or even older Freon-based refrigeration systems. However, these refrigerants may not be ideal in industrial settings because of their expense and the damage they exert on the environment. One of the preferred alternatives is ammonia as a refrigerant.
Ammonia refrigeration is a trusted, effective system with a long history of reliable and proven use. Ammonia is used to transfer heat from one place to another for dissipation. Concentrated ammonia is useful for keeping things cool due to its high latent heat value meaning it has the ability to pick up large amounts of heat from a space.
What Is Refrigeration?
Refrigeration lowers and maintains the temperature of a space, material, or system below that of the surrounding air, while the heat extracted is rejected at a higher temperature. Therefore, this process is a type of mechanical cooling.
Four essential parts must be present in a system for the refrigeration cycle to function. These include the following:
The compressor is the principal part of the system, as it is the main driver of the refrigerant. It compresses the gas and generates a pressure differential that propels the refrigerant through the system in a constant cycle.
The refrigerant gas leaving the compressor is de-superheated, condensed, and transformed from a vapor to a liquid by the condenser, thus allowing it to do work once again.
The expansion valve limits the flow of liquid refrigerant while creating a pressure differential with the evaporator.This pressure differential creates what is called flash gas and allows the refrigerant to cool itself prior to entering the evaporator. Since it determines the amount of refrigerant entering the evaporator, it is more frequently referred to as a metering device.
Before returning to the compressor, the heat from the room enters the evaporator and transfers into the refrigerant by boiling the liquid refrigerant inside of the cooling coil.
How Does Refrigeration Work?
In a nutshell, the following describes the path of a fully functioning refrigeration system:
- The refrigerant’s low-pressure vapor form is introduced into the compressor.
- The compressor compresses the gas, resulting in a high-pressure, superheated gas.
- The super-heated gas starts to cool down inside the condenser and transform into vapor. The refrigerant vapor is further cooled within the condenser, condensing into a high-pressure liquid.
- The ammonia is then metered through an expansion valve cooling down the liquid refrigerant and preparing it to do work once again.
- The evaporator allows the transfer of heat from the room into the refrigerant where it is once again compressed by the compressor, thus repeating the cycle.
Ammonia Refrigeration System: Key Points To Ponder
To ensure that the right processes and standards are followed while starting up ammonia industrial refrigeration systems, remember that this process could be influenced by the kind of equipment used, where it is located, and what each refrigeration system does.
Before proceeding, ensure the following have been checked:
- The insulation, electrical components, and plumbing have all been installed properly.
- All safety measures have been evaluated and established.
- The devices and associated piping have undergone pressure testing.
- Sufficient connections have been made for the test and startup equipment.

Understanding Food and Beverage Refrigeration ComponentsLeave a Comment
Refrigeration systems are necessary for food and beverage establishments, including supermarkets, and restaurants, but also manufacturing facilities, breweries, and processing plants. . Your entire business might be jeopardized if your refrigeration system fails. Therefore, it is critical to understand refrigeration components for food and beverage applications.
The purpose of refrigeration in the industrial setting is to maintain the optimal temperature for processing, packaging, and storing food and beverages.
Main Refrigeration Components
To understand how refrigeration systems work to keep food and beverages cool, it is crucial to look at their inner workings. The following are the main components of refrigeration:
The compressor is the principal part of the procedure, as it is the main driver of the refrigerant it works like a pump to circulate the refrigerant. It compresses the gas and generates a pressure differential that propels the refrigerant through the circuit in a constant cycle.
Next, the condenser is filled with superheated, pressurized refrigerant. Then, it cools the refrigerant and converts it to a liquid form.
Condensers are classified into three categories:
This type of condenser is often found in smaller refrigerators and is also known as a coil condenser because of its aluminum or copper coils at the back. These coils help increase the surface area of the refrigerant for cooling.
Air-cooled condensers are divided into two types: the natural convection condenser — which uses the natural flow of air to chill the refrigerant — and the forced convection condenser, which employs a fan to draw in cold air.
This type of condenser is utilized in large factories. They use water to cool the refrigerant, often performing better in higher ambient temperatures. It is further subdivided into three types: tube-in-tube or double pipe type, shell and coil type, and shell and tube type.
Evaporative condensers are the primary condenser used for industrial applications. The evaporative condenser leverages not only air cooling, but the added effect of evaporative cooling utilizing water. Evaporative condensers are the most efficient and allow for lower head pressure to run a system more efficiently.
The expansion valve helps lower refrigerant pressure and temperature. The abrupt reduction in pressure produces a cooling effect called “flash gas” bringing the refrigerant down in temperature. The expansion valve also controls how much refrigerant is needed to fulfill load requirements.
Expansion valves come in various types: capillary tube, constant pressure, automatic throttling valve, thermostatic expansion valve, float valve, and motorized valve
An evaporator is tasked with absorbing heat inside the refrigeration system. It also serves as a medium for heat transfer from the stored load to the refrigerant. This refrigerant is then transformed into a vapor where it is later compressed by the compressor.
