Technical and practical skills are only part of what makes a professional repair technician. In addition, familiarity with safety and environmental standards is also crucial.

Using appropriate refrigerants, preventing leaks of hazardous materials, and following safety guidelines when handling high-pressure equipment are essential measures. Since many supermarket cold storage units operate 24/7, technicians must be prepared to work in emergency situations and outside of regular working hours.

In Tehran, due to the high concentration of supermarkets and the extensive need for cold storage maintenance and repair, the demand for skilled technicians remains high. The variety of brands and models of cold storage units requires continuous updating of technical knowledge and familiarity with new technologies.

Ongoing training, knowledge of manufacturer guidelines, and hands-on experience are key factors that can enhance the skills and efficiency of a supermarket cold storage repair technician in Tehran.

Actions Taken by a Supermarket Cold Storage Technician to Prevent Refrigerant Leaks and Reduce Environmental Impact

Refrigerant leaks in cooling systems, especially in supermarket cold storage units, are a common issue that can lead to reduced cooling efficiency, increased energy consumption, and environmental damage. A cold storage repair technician is responsible for using proper methods and professional standards to prevent leaks and minimize their environmental impact.

These measures include regular inspections, using precise tools to detect leaks, employing correct repair techniques, and replacing refrigerants with environmentally friendly alternatives.

One of the most important steps in preventing refrigerant leaks is conducting regular preventive inspections by the cold storage repair technician. Checking the condition of pipelines, connections, and control valves periodically can prevent potential leaks.

Cold storage technicians typically use leak detection devices such as electronic leak detectors, foaming solutions, and gas sensors to accurately identify leak locations. If signs of reduced refrigerant levels or system pressure drops are observed, more detailed inspections are performed, and corrective actions are taken promptly.

In addition to timely leak detection, using standard methods for repairing and maintaining refrigeration systems is crucial. Welding and soldering of pipes should be performed with precision and adherence to safety standards to prevent leaks at connection points.

Furthermore, using high-quality O-rings, gaskets, and sealing materials can prevent refrigerant leakage in critical areas. When refilling the system with refrigerant, maintaining the exact amount and standard pressure is essential, as excess or insufficient refrigerant can cause excessive pressure and lead to leaks.

Choosing the right refrigerant also plays a vital role in reducing environmental impact. Many older refrigerants, such as R22, are being phased out due to their harmful effects on the ozone layer and global warming. Cold storage technicians should be familiar with alternative refrigerants such as R134a, R404A, and other environmentally safer options for use in new systems or during refilling.

Additionally, new technologies such as natural refrigerants, including ammonia and carbon dioxide, are considered viable options for cold storage systems due to their lower environmental impact.

Another effective measure in reducing environmental impact is optimizing system performance to minimize leaks and energy consumption. Proper system settings, condenser and evaporator pressure control, appropriate insulation, and checking expansion valve performance all help reduce excess system pressure and prevent leaks.

In many cases, installing smart monitoring systems can help technicians detect potential leaks before serious issues arise and take corrective actions more quickly.

The Importance of Thermostat Replacement and Adjustment by a Supermarket Cold Storage Technician

The thermostat is a key component in supermarket cold storage refrigeration systems, playing a critical role in temperature regulation and maintaining optimal conditions for food storage. The proper functioning of this component directly affects product quality, energy consumption, and equipment lifespan.

Therefore, a supermarket cold storage repair technician must periodically inspect the thermostat and, if necessary, make adjustments or replace it. Neglecting the performance of this component can lead to temperature fluctuations, reduced cooling system efficiency, and ultimately, food spoilage.

The thermostat measures the cold storage temperature and sends a signal to turn the compressor on or off when necessary. If this component malfunctions, the compressor may overwork, leading to increased energy consumption and mechanical wear.

On the other hand, if the thermostat fails to detect low temperatures correctly, the cooling system will not function properly, potentially causing food spoilage. This is especially crucial in supermarkets, where large quantities of perishable products are stored in cold storage units.

Replacing the thermostat is necessary when its performance is compromised. Before replacing it, the cold storage repair technician must examine the type of thermostat and its operating mechanism. Some thermostats are mechanical, while others are digital and programmable.

Digital models offer greater precision and advanced settings but require regular inspections and updates. When replacing the thermostat, the technician must ensure that the new model is fully compatible with the refrigeration system and is installed correctly for optimal performance.

Precise thermostat adjustment is also highly important. In many cases, incorrect settings result in unnecessary compressor operation and increased operating costs. The technician must determine the appropriate temperature based on the types of products stored in the cold storage unit.

For instance, dairy products require different temperatures than meat or vegetables. Additionally, environmental factors such as humidity and air pressure should be considered when adjusting the thermostat to prevent evaporator freezing or excessive temperature rises.

Supermarket Cold Storage Technician and Compressor Failure Diagnosis

A supermarket cold storage repair technician must diagnose compressor failures by identifying symptoms such as reduced cooling efficiency, abnormal compressor temperature increases, unusual noises, and pressure fluctuations in the refrigeration cycle.

First, the technician inspects the system’s suction and discharge pressures using pressure gauges, and if abnormal pressure levels are detected, issues with internal compressor components like valves or pistons may be suspected.

Additionally, a multimeter is used to check the compressor’s electrical windings and power consumption to determine potential burnout or short circuits. In some cases, the compressor oil is also analyzed, as color changes or the presence of metallic particles may indicate internal wear.

Once the problem is accurately diagnosed, the technician proceeds with repairing or replacing faulty components and tests the system to ensure that cooling efficiency is restored to optimal conditions.
