What is a Freon Cold Store?

A freon cold store, is a cooling appliance that utilizes Freon refrigerant within its refrigeration system to achieve and maintain low temperatures. Operating within a range typically between +18 and -45 degrees Celsius, Freon refrigeration cycles are commonly employed in various refrigeration facilities. Today, Freon refrigerants are extensively used in household refrigerators, car coolers, air conditioning units like chillers, and commercial cold stores.

The primary objective of a Freon cold store unit is to establish a controlled and conducive environment for the preservation of perishable goods such as food, medications, and other temperature-sensitive products. The functionality of the Freon cold storage system revolves around extracting heat from the interior space of the cold store, effectively lowering the temperature and ensuring the quality and freshness of the stored items. These systems play a pivotal role in extending the shelf life and ensuring the safety of perishable goods stored within cold storage facilities by efficiently removing heat and maintaining the desired low temperature.

 Introduction to Types of Freons

Freon refrigerants play a pivotal role in various refrigeration and air conditioning systems across different industries. In this overview, we’ll delve into the common types of Freon refrigerants and their distinct characteristics.

1. R22 (Chlorodifluoromethane): Also known as HCFC-22, R22 is a high-efficiency Freon refrigerant. Despite its effectiveness, its production has been halted in many countries due to its ozone-depleting properties. Unfortunately, the release of R22 poses significant environmental risks due to its ozone-depleting nature.
2. R134a (Tetrafluoroethene): R134a is an HFC refrigerant introduced as an alternative to R22. While it has lower efficiency at temperatures needed for cold room, R134a has a lesser environmental impact and plays a minimal role in ozone layer depletion. Operating at moderate pressures, R134a finds suitability in high-temperature applications such as chillers, car air conditioners, and refrigerators. Occasionally, it may be utilized in constructing cold storage units above Safari.
3. R404a (Tetrafluoroethane and Pentafluoroethane Combination): R404a is a blend of HFC refrigerants, comprising Tetrafluoroethane and Pentafluoroethane. It is commonly employed in low and medium temperature refrigeration applications, including subzero cold storage and freezing tunnels. Notably, R404a exhibits exceptional efficiency at low temperatures, making it ideal for sub-zero freezers and freezing tunnels.

Understanding local regulations and industry guidelines is imperative in selecting the appropriate refrigerant for specific applications. Compliance with environmental standards ensures sustainable practices while optimizing system performance for efficient operations.

 Components of a Freon Cold Storage System

Freon refrigeration systems typically cater to small to medium-sized refrigeration facilities. These systems comprise essential equipment such as a compressor, evaporator, condenser, receiver tank, electrical panel, valves, and control devices. These components work cohesively to regulate temperature, ensuring the preservation of freshness and quality for temperature-sensitive goods.

Freon Cold Store Compressor

Within the refrigeration cycle, the compressor serves two primary functions: compressing the refrigerant and facilitating its flow. Compressors come in various types, each with its distinct advantages and disadvantages, selected based on specific usage, requirements, and limitations. Typically, hermetic and semi-hermetic piston or screw compressors are employed in constructing freon cold storage facilities. Additionally, in certain conditions, open-type compressors may also be utilized in Freon cold room construction.

Freon Evaporator

The evaporator functions as a heat exchanger, facilitating the absorption of heat from the interior of the cold store by the refrigerant (Freon), causing the refrigerant to evaporate. This evaporation process occurs within the evaporator coil, utilizing direct expansion (DX) facilitated by the expansion valve. As a result, the temperature within the cold room decreases as heat is absorbed from the surrounding environment and the products stored within. Freon cold storage evaporators typically employ a combination of copper tubing and aluminum fins within a coil, complemented by reverse fans to generate a cold air flow.

 Freon Condenser

The condenser, functioning as a heat exchanger, plays a crucial role in extracting heat from the refrigerant compressed by the compressor, transitioning it from a high-pressure gas to a liquid state. It effectively transfers heat from inside the cold room, as well as heat generated during motor operation, to the surrounding environment. This process allows the refrigerant to release thermal energy, enabling it to condense once more and reenter the cycle. Condensers come in various types selected based on geographical conditions and operational limitations. Air-cooled condensers, comprised of coils with copper tubing and aluminum fins, along with axial fans, are commonly utilized in the construction of Freon cold storage system. Additionally, in situations where water is available, water-cooled condensers and cooling towers may be employed. Water-cooled condensers typically adopt the form of shell and tube heat exchangers.

 Refrigerant Receiver Tank

The receiver tank functions as a storage reservoir for liquid refrigerant within the system. As refrigerant flows throughout the system, the receiver ensures a consistent supply of refrigerant to the evaporator, facilitating efficient and uninterrupted cooling. Typically positioned slightly lower than the condenser, the receiver tank utilizes gravity to accumulate refrigerant gas after it condenses into a liquid within the condenser.

 Electrical Panel

The electrical panel is one of the components of the freon cold storage system, which is responsible for controlling and distributing electrical power to other components of the refrigeration system. The electrical panel actually acts as a center for managing electrical connections, fuses, pressure and temperature switches, and other control devices. The panel manages the safe and efficient operation of various components in cold room such as compressors, evaporators, fans and lighting. The switchboard also provides the possibility of accurate monitoring and, if necessary, remote monitoring, troubleshooting and adjustment of electrical parameters to maintain optimal performance and safety.

 Valves and Control Devices in Freon Cold Storage

Valves and control devices represent integral components within cold storage equipment, essential for the precise regulation and management of refrigerant flow and system performance. Various types of valves, including expansion valves, shut off valves, solenoid valves, filters and strainers, sight glasses, and vibration absorbers, are strategically incorporated into the refrigeration system to oversee refrigerant flow, pressure, and temperature. These valves ensure proper refrigerant distribution, optimize system efficiency, and safeguard against potential issues such as pressure or temperature fluctuations.

Additionally, control devices such as thermostats, pressure and temperature switches, electronic controllers, among others, play pivotal roles in monitoring and supervising the safe operation of Freon refrigeration equipment. Controllers facilitate accurate temperature regulation, system automation, and implementation of safety protocols. They uphold optimal temperature levels within the cold storage environment, issue alerts for any anomalies, and permit adjustments to enhance energy efficiency and operational effectiveness.

Valves and controls collaborate synergistically to uphold the reliable and efficient operation of refrigeration equipment. Through their meticulous integration and configuration, they ensure optimal performance, temperature stability, and safety within Freon cold storage facilities. This concerted effort helps preserve perishable goods and sustain ideal storage conditions for prolonged freshness and quality.
