Everything you need to know about refrigeration evaporators Part 1
Refrigeration evaporators play a fundamental role in any refrigeration or freezing system, whether incorporated in a compact system or as a stand-alone unit. But do you really know what an evaporator is or how it works? What is a refrigeration evaporator and what is it used for? In refrigeration, an evaporator is the heat exchanger where the refrigerant circulating inside the refrigeration circuit absorbs the thermal energy from the environment, which is then cooled. This is how the state of the refrigerant...

Direct and indirect cooling systems
Refrigeration systems have more than one application, such as food preservation, equipment cooling, etc. It extracts heat from one environment and transfers it to another, thus cooling it first. We have a wide variety of refrigeration systems, all of them different, which gives us the possibility to choose the cooling system that best suits our needs, what we are looking for. In order to know which is the best in each situation, we must define them at various levels, and identify their...

Other food preservation processes
In addition, there are other types of preservation processes which, although with different qualities, also aim to preserve the optimum conditions for food consumption, among which the following stand out: • Ultra-freezing: consists of subjecting food to temperatures below -40ºC for relatively short periods of time (

The importance of refrigeration in food
Most of the foodstuffs consumed daily nowadays need to be refrigerated because they are perishable (meat, fish, fruit, vegetables, etc.). For this reason, it is essential to guarantee their safety for as long as possible, thus avoiding possible health problems. What is the importance of refrigerating food? It has been proven that refrigeration of food at an optimum temperature plays a fundamental role in maintaining food safety. In many cases it is necessary to control and maintain the storage temperature, which will...

Food Refrigeration
Nowadays, refrigeration and freezing are the two most widespread methods of food preservation. Food refrigeration is a preservation process based on the reduction or maintenance of a controlled temperature for a given time and space, usually in cold rooms. This process is based on the extraction of energy from bodies with high thermal energy, thus reducing their energy, and consequently bacterial activity, in this case, in the preservation of foodstuffs. When we talk about thermal energy, we refer to the temperature of...

Industrial or Commercial Refrigeration Compressors
Industrial or commercial refrigeration compressors are the fundamental part of the equipment and systems responsible for supplying and satisfying the refrigeration needs of a specific space, chamber, process… Compressors: the core of refrigeration systems What is a refrigeration compressor? The compressor is the main component of refrigeration equipment. its function is to compress the refrigerant gas or fluid, thus allowing pressure changes to occur in the refrigerant gas or fluid, causing it to move along the refrigerant circuit.These changes in pressure and temperature...

Reciprocating or Piston Compressors
The refrigerant is compressed inside a cylinder thanks to the reciprocating motion of a piston by means of a crankshaft driven by an electric motor. This type of compressor is characterised by: • They have inlet and exhaust valves that allow a more constant flow. • The use of silent-block, in order to mitigate the high vibrations to which this type of compressor is subjected. • Oil level sight glass and crankcase resistance. • Connection for oil balancing. • Possibility of individual, tandem, trio or...

How should we defrost food
Defrosting is just as important a process as freezing if we want to obtain quality food. In this case, the rules are just the opposite of those for a freezing process. While freezing processes should ideally be carried out in the shortest possible time, when it comes to thawing, the ideal is just the opposite, that they should be as slow as possible (within reasonable limits). A very common practice to avoid whenever possible is to defrost food at room temperature, as...

Radairan 20,000 CFM Air Handling Unit
The Radairan 20,000 CFM air handling unit is a device responsible for filtering air, controlling air speed, regulating air humidity, and more. Additionally, it is also used for cooling the environment. Therefore, it can be said that the price of the air handling unit is very cost-effective given its numerous applications. Air handling units can be broadly classified into two categories: building air handling units and industrial air handling units. These devices do not differ structurally; they only vary...
