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...

Refrigeration solutions for the meat industry

RADIRAN has designed wall-mounted evaporators for deep-freezing tunnels with high-flow motor fans and high static pressure available together with high-efficiency coils, in order to reduce freezing time and promote the formation of smaller crystals. To service these high cooling capacity demands, RADIRAN offers solutions and refrigeration systems using natural refrigerants (such as ammonia (R-717), propane (R-290) or CO2 (R-744) ready for commissioning thanks to their Plug & Play configuration. Cutting or processing rooms are among the areas with the highest risk of contamination, being classified...

Refrigeration as a quality and safety contribution to the meat industry

“In order to contribute to the availability of food for a constantly growing population, demanding with the quality of the products of the meat industry" Meat becomes an ideal culture medium for the growth of almost any micro-organism. This is due to its nutritional qualities, neutral post-mortem pH (pH = 6.5), high water activity (aw = 0.98), and extrinsic factors such as temperature and oxygen concentration. Meat and meat products are perishable by nature and easily susceptible to microbial contamination and chemical...

فرآیند دیفراست بخش دوم Defrost Process

Defrost Process – Part two

Air defrosting In refrigeration, air defrost is an effective method of combating ice build-up in evaporators. This process uses the air in the chamber itself to defrost the frost efficiently. Its suitability is intensified in chambers above 4ºC, as at lower temperatures its effectiveness is reduced. The system starts with the closing of the liquid solenoid valve, which stops the refrigerant flow to the evaporator and to be emptied by the compressor until it stops. In this case the fans recirculate the air...

Defrost Process

The defrost process in refrigeration systems is crucial for the correct operation of the equipment and allows the removal of the frost generated after dehumidification and subsequent freezing of the humidity in the air.     First, we plan a defrost schedule, where we agree on the frequency of defrosting. Initially, by closing the refrigerant solenoid valve to prevent the refrigerant from entering the evaporator, the compressor sucks the remaining refrigerant until it stops due to low pressure. This process allows the system...

Cold rooms according to their size

Panels, floors and roofs, usually made of sandwich panels. The sandwich panel is composed of two steel sheets protecting an insulating core of high density polyurethane. This panel is responsible for the most efficient and durable cooling of the cold room. Airtight door. It can be sliding or pivoting, and incorporate an air curtain, or louvres to mitigate cold losses with each door opening. Humidifiers or dehumidifiers. These allow humidity (relative humidity) to be added to or removed from the cold room in such...

Cold rooms Definition

Cold rooms are spaces where, thanks to a refrigeration system that establishes certain climatic conditions, the conservation or manufacturing process of different products is favored. They are a fundamental element in many sectors. From the food and HORECA sector for the correct preservation of food, to the industrial sector for production processes where refrigeration is involved. For example, in a vehicle test tunnel, where a cold room simulates certain climatic conditions, or in the manufacturing process of medicines such as insulin. Cold rooms can...

Performance study of spiral finned tubes on heat transfer

The study titled "Performance study of spiral finned tubes on heat transfer and wake flow structure," published in the International Journal of Heat and Mass Transfer, investigates the turbulent flow and heat transfer characteristics of heat exchangers utilizing spiral finned tubes (SFT). The research employs large eddy simulation (LES) to analyze the flow dynamics and temperature distribution around these tubes, aiming to enhance the understanding of how vortex structures influence heat transfer efficiency. Objectives and Methodology The primary objective of the...
