Investing in training and attracting skilled personnel in this field will guarantee the food and pharmaceutical security of the capital.

Technical Competencies Required for Below-Zero Cold Storage Installers and Repair Technicians
The first and most fundamental competency for a professional installer or technician is a full understanding of the vapor compression refrigeration cycle. Knowing how the compressor, condenser, expansion valve, and evaporator work, along with analyzing the relationships between pressure, temperature, and refrigerant flow rate, are essential foundations for precise installation and repair. Any mistake in identifying the fault location or choosing an inappropriate capacity for one of these components can cause system inefficiency or even serious damage.

Skill in Selecting and Installing Proper Capacity Equipment
Below-zero cold storage installers and repair technicians must be capable of performing cooling load calculations to select the appropriate equipment capacity based on the product type, space volume, environmental conditions, and heat load entry and exit rates. This skill includes selecting the right compressor, evaporator and condenser model, refrigerant type, and determining the precise type and thickness of thermal insulation.

Mastery of Refrigerants and Related Safety Considerations
Considering the use of various refrigerants in below-zero cold storages such as R-404A, R-507, R-22, or even newer low-GWP refrigerants, technicians must be familiar with their thermodynamic properties, charging methods, recovery, and discharge procedures. Also, adhering to safety protocols during leak detection, refrigerant charging, or working under high pressure is critical; neglect can lead to irreparable damages.

Ability for Specialized Troubleshooting and Use of Precision Instruments
The below-zero cold storage repair technician must be able to analyze and interpret data obtained from tools such as pressure gauges, multimeters, digital thermometers, electronic leak detectors, and data loggers. Visible signs of malfunction, such as sudden temperature drops, abnormal freezing, or unusual compressor noise, must be quickly linked to precise technical causes to correctly resolve faults. Familiarity with digital controllers and PLCs in advanced systems is also a significant advantage.

Skill in Professional Connections, Piping, and Insulation Work
Proper execution of copper piping with correct slope, allowable distances between units, minimal pressure drop in suction and discharge lines, using flare or standard silver brazing, and precise insulation of piping and cold storage body, are vital skills for every below-zero cold storage installer and technician. Even the slightest defect in these steps can cause leaks, energy loss, and reduce system lifespan.

Understanding Control Concepts and Ability to Work with Electrical Panels and Alarm Systems
Many industrial cold storages use electrical panels equipped with temperature alarm systems, digital thermostats, compressor speed controls, and voltage protection. A professional technician must be able to read electrical diagrams, test components such as fuses, contactors, thermostats, and troubleshoot electrical faults. Also, skill in configuring smart controllers like CAREL or Dixell will enhance the operational efficiency of the cold storage.

In a city like Tehran, where specific environmental factors such as traffic, power outages, space limitations, and high operational load in cold storage facilities are common, installers and technicians must also possess supplementary skills such as high responsiveness, precise planning, familiarity with various equipment brands available in the market, and readiness for emergency services. Additionally, the ability to document operations, provide technical reports, and communicate effectively with employers plays an important role in increasing customer satisfaction and trust.
Ultimately, the technical capabilities of a freezer cold storage installer and technician go beyond merely installing or replacing parts. This profession requires deep scientific understanding, precise execution skills, full adherence to safety, and the ability to interact with modern technologies.

Professional Troubleshooting Techniques by Freezer Cold Storage Installers and Technicians in Critical Conditions
Initial Inspection: Analyzing Signs of Abnormal Operation
Before taking any action, a professional technician must carefully examine initial signs such as temperature fluctuations inside the cold storage, abnormal compressor noise, increased suction or discharge pressure, or unusual evaporator freezing, to identify the troubleshooting path. This stage requires a thorough understanding of pressure–temperature relationships in the refrigeration cycle. Ignoring these signs may lead to overlooking serious issues such as oil return, refrigerant leakage, or compressor overload.

Using Precise Measuring Tools and Data Analysis
Next, the freezer cold storage installer and technician must gather necessary data using specialized equipment such as digital or analog pressure gauges, laser or probe thermometers, multimeters, and, if needed, electronic gas leak detectors.
Analyzing these data (for example, temperature difference between evaporator inlet and outlet, suction pressure compared to normal conditions, or voltage drop in the control panel) plays a key role in locating the exact failure point. For systems with digital controllers, reading error codes is also part of this stage.

Identifying and Fixing Refrigerant-Related Issues
One of the most common disruption factors in freezer cold storages is problems related to refrigerant quantity and quality. Gradual efficiency reduction or sudden temperature drop can indicate gas leakage. The technician checks connections, welds, and valves using a leak detector and, after fixing the leak, vacuums and recharges the system. Also, if moisture or contamination enters the circuit, replacing the filter drier and cleaning the refrigeration circuit is mandatory.

Analyzing Compressor and Moving Parts Performance
In critical conditions, the compressor may overheat, produce abnormal noises, or even experience mechanical lock-up. An experienced technician evaluates compressor health by testing current consumption, checking input voltage, coil resistance, and operating pressure. If necessary, start capacitors, relays, and thermostats are inspected or replaced. Sometimes, oil control problems or liquid refrigerant return can also cause compressor failure.
