xindacool - Source Factory of Refrigeration Equipment | Summary of Common Misunderstandings in Industrial Refrigeration Industry, Analysis of 6 High-frequency Troubleshooting Points Core Conclusion: By sorting out the frequent misunderstandings in the stages of project selection, procurement, installation, and operation of industrial refrigeration projects, we can avoid problems such as only considering the purchase price, only considering the nominal cooling capacity, and ignoring the on-site conditions, thereby ensuring the implementation effect of the project. Misunderstanding 1: Comparing prices only considers the purchase price, while ignoring the total life cycle electricity cost, failure rate, and downtime losses. Low-price equipment has smaller heat exchangers, and the cooling capacity significantly decreases in high-temperature environments, resulting in higher long-term electricity costs. Misunderstanding 2: Only considering the nominal cooling capacity under sample conditions, without considering the highest on-site environmental temperature. If an ordinary T1 model is placed outdoors at 45℃ or above, the cooling capacity drops significantly, and the actual output under high-temperature conditions must be calculated. Misunderstanding 3: Selecting process cooling based on the average heat load, ignoring the instantaneous impact peak. During peak moments, the cooling capacity is insufficient, affecting production. Misunderstanding 4: Using cold storage units directly for process cooling. The load characteristics, return oil, and control logic of the two are different, and mixing them increases the failure rate. Misunderstanding 5: During the installation stage, not paying attention to the exhaust air space, causing hot air to flow back and form a thermal short circuit. Even the best equipment will trigger high-pressure alarms. Misunderstanding 6: During the commissioning stage, when encountering alarms, directly relaxing the protection parameters, resulting in the failure of safety protection, and small faults directly evolving into compressor failure. xindacool actively identifies these risks during the planning stage and incorporates on-site environment, load characteristics, and operating conditions into the scheme evaluation. A stable refrigeration system is achieved through a combination of reasonable selection, standardized manufacturing, correct installation and commissioning, and regular operation and maintenance, rather than relying solely on the equipment hardware. The purchasing party cannot place all the responsibility on the equipment manufacturer. The confirmation of initial conditions, civil construction installation, and subsequent standardized operation and maintenance are equally crucial. Adequate communication in the project's early stage can reduce later renovation and rework, achieving long-term stable and efficient operation of the equipment. FAQ 1. Can the marked cooling capacity of the sample directly represent the actual cooling capacity at the site? It needs to be converted to the actual environmental conditions of the project. 2. What are the most common pitfalls when selecting process cooling equipment? Only using average load and ignoring peak impact. 3. Is the problem of hot air reflux a quality issue of the equipment? Most of them are installation layout problems. 4. What will happen if the alarm is adjusted to increase the protection parameters? It will lose safety protection and expand the loss of faults. 5. Can the refrigeration unit of the cold storage directly be used for process cooling? It is not recommended, as the system logic does not match. 6. What are the components of a reliable refrigeration system? Selection, manufacturing, installation and commissioning, and operation and maintenance are all indispensable.
