KEY COMPONENTS:

Dynamic evaporator:
Axial fan: Integrated with the evaporator for active air circulation within the chamber, ensuring uniform temperature distribution.
Fins and tubes: Increase the heat exchange surface area, allowing for more efficient air cooling.

Compressor:
Hermetic or semi-hermetic compressors: Used to maintain a constant temperature, designed for operation in positive mode.

Condenser:
Air-cooled condensers: Common for these applications, allowing efficient heat transfer from the refrigerant to the surrounding air.

Expansion valve:
Thermostatic expansion valve (TEV): Precisely controls the refrigerant flow into the evaporator, maintaining optimal cooling conditions.

Control system:
Digital thermostat: Provides precise temperature control inside the chamber.
Temperature sensors: Continuously monitor the conditions and adjust system operation.

ADVANTAGES OF THE DYNAMIC EVAPORATOR:
Uniform temperature distribution: Dynamic evaporators use fans to actively mix the air, resulting in a more consistent temperature profile within the cooling chamber.
Faster temperature stabilization: Due to efficient air circulation, the desired temperature is reached more quickly, reducing the time needed to cool new products entering the chamber.
Reduction in temperature variations: Active air circulation minimizes temperature differences across different sections of the chamber, ensuring consistent storage conditions.
Improved energy efficiency: Better temperature distribution means the compressor operates more efficiently, reducing overall energy consumption.


APPLICATIONS:

Food industry:
Storage of fresh products: Fruits, vegetables, dairy products, meat, and fish require precise temperature control to maintain freshness and quality.
Fermentation and aging: Products such as cheeses and meats need specific conditions for fermentation and aging.

Hospitality:
Restaurants and hotels: Storage of large quantities of food and beverages for daily use, focusing on fast inventory turnover.
Catering: Preparation and storage of food before transport to events.

Retail:
Supermarkets: Refrigerated display cases and storage chambers for fresh food, ensuring products stay fresh and safe for consumption.
Mixed goods stores: Storage of products like milk, meat, fruits, and vegetables.

Pharmaceutical industry:
Storage of medications: Products requiring controlled temperatures above freezing.
Biological samples: Storage of samples that cannot be frozen but need stable cold conditions.


MAINTENANCE:

Regular cleaning: The interior of the chamber, fans, and evaporator should be cleaned regularly to prevent contamination and ensure smooth operation.
System checks: Regular inspections of the compressor, condenser, evaporator, and expansion valve ensure proper operation and early detection of potential issues.
Parts replacement: Timely replacement of faulty parts prevents major failures and ensures continuous system operation.
Calibration of control systems: Ensuring that thermostats and sensors are functioning correctly and precisely controlling the temperature.

This comprehensive approach ensures that dynamic evaporators and the entire cooling system operate at their peak efficiency, providing consistent and reliable performance in various applications.
