Sister Liu, who runs a community convenience store, recently planned to install an additional small cold storage unit. However, faced with a wide variety of products on the market, she was stuck in a dilemma—worried that a unit too small would be insufficient and one too large would waste electricity. Finally, under the guidance of a refrigeration technician, she considered three dimensions and quickly finalized a suitable plan.

         The first dimension is capacity demand. Sister Liu's convenience store mainly stores beverages, ice cream, and a small amount of ready-to-eat food. Previously, with ordinary refrigerators, she had to restock twice a day. The technician suggested choosing a 12-cubic-meter unit, which can store enough goods for 3 days. This not only eliminates the need for frequent restocking but also avoids increased energy consumption due to excessive space. Sister Liu did a quick calculation: she used to spend 1 hour restocking every day, but now with restocking once every 3 days, she saves more than 20 hours a month and also reduces losses during transportation.

         The second dimension is cooling speed. The convenience store has a concentrated customer flow in the evening. If the cooling speed is slow after restocking in the afternoon, the ice cream tends to melt. The technician recommended a unit with a cooling capacity of 3HP. This type of unit can lower the temperature from room temperature to -10℃ within 30 minutes. Even if the store is fully restocked before the evening rush, it can quickly reach the required storage temperature. After trying it out, Sister Liu found that previously, the ice cream restocked in the afternoon would be slightly soft, but now, no matter when she restocks, the texture is as good as when it was just delivered from the manufacturer.

         The third dimension is installation conditions. The height of the back kitchen in Sister Liu's convenience store is only 2.3 meters, which cannot accommodate ordinary vertical units. The technician recommended a horizontal unit to her. This type of unit is only 1.5 meters high, can be installed against the wall, and does not take up operating space. During installation, the technician also specially adjusted the unit's position to point the heat dissipation port towards a well-ventilated area, further improving cooling efficiency.

Now, Sister Liu has been using the small cold storage unit for more than a month. She said with a smile: "I used to think choosing equipment was difficult, but I didn't expect that by considering these three dimensions, there's no hesitation at all, and it's really easy to use!"
