Manager Wang, who is in charge of the cold chain area of a logistics warehouse, encountered problems due to improper compressor selection when upgrading the cold storage units last year. The piston compressor previously used in the warehouse was so noisy during operation that it affected the work in the adjacent sorting area. More critically, its cooling capacity was insufficient — during high temperatures in summer, the temperature inside the warehouse always fluctuated between -15℃ and -12℃, failing to meet the -18℃ standard for frozen meat storage. Eventually, two boxes of imported beef spoiled, resulting in a direct loss of nearly 10,000 yuan. This lesson made him realize that as the "heart" of a cold storage unit, the quality of the compressor directly determines the unit's cooling effect, energy consumption, and stability. The core lies in "accurately matching the usage scenario".

           For small and medium-sized businesses, scroll compressors are the first choice for cost-effectiveness. For example, a small cold storage of about 10 cubic meters in a community supermarket is fully sufficient with a 3HP scroll compressor. Manager Wang specifically consulted a friend who runs a convenience store, and the friend uses this type of compressor. Its daily operation noise is as low as 45 decibels, quieter than a household refrigerator, so it will not disturb customers. Its energy consumption is also 15% lower than that of traditional piston compressors, saving nearly 200 kWh of electricity per month, which is a considerable sum over a year. Moreover, maintenance is simple — only the air filter needs to be replaced every quarter, without the need to frequently call technicians for on-site visits.

          However, for large-scale logistics cold storages like the 80-cubic-meter one managed by Manager Wang, screw compressors are a must. He finally decided on a 15HP screw model. In actual use, its cooling capacity is three times that of a scroll compressor. For the room-temperature frozen meat that is batch-stored every morning, it can stably lower the warehouse temperature to -18℃ within one hour, fully meeting the cold chain turnover needs. What's more reassuring is that this compressor has only undergone two regular lubricating oil changes in more than a year of operation, and its failure rate is much lower than that of the previous piston type. Even when operating under high load 24 hours a day, it has never failed.
