Selection and maintenance of air cooling and direct cooling for beverage cabinet

The choice of air cooling and direct cooling in supermarket beverage cabinet should be comprehensively considered based on the use scenario, maintenance needs and budget. Generally, most shopping malls use air cooling and most households use direct cooling. Why is this choice? The following is a detailed analysis.

1. Core Performance Comparison (Details Table)

As can be seen from the above table, the core features of air cooling and direct cooling are listed below for different scenarios to select the configuration according to the core dimension:

(1) Air-cooled type

It is easy to see from the above performance table that the biggest advantage of air cooling is that it is not easy to frost, while supermarkets and convenience stores need to focus on refrigeration and display effect, so frost can not meet the display of beverages, so the air cooling type display cabinet is the best choice.

Moreover, in high-traffic venues like supermarkets, air-cooled displays can rapidly cool down to prevent beverages from warming. For example, the Nenwell NW-KLG750 air-cooled display cabinet maintains a temperature difference of no more than 1℃ through its three-dimensional airflow system, making it ideal for displaying temperature-sensitive items like carbonated drinks and beer.

There are also many large-capacity models available. The NW-KLG2508 features four-door access and a massive 2000L capacity, with its forced circulation system designed to cover larger spaces. For example, the Haier 650L air-cooled display cabinet supports precise temperature control ranging from-1℃ to 8℃.

For small convenience stores, the NW-LSC420G single-door beverage cabinet is an ideal choice. Featuring a 420L capacity air-cooled unit, it maintains a consistent refrigeration temperature of 5-8°C after 120 door cycles during 24-hour testing.

(2)Select direct cooling scenarios

Direct-cooling beverage cabinets are budget-friendly, making them ideal for households with tight budgets. These units deliver excellent value for money, with Nenwell’s single-door direct-cooling cabinet being 40% cheaper than air-cooled models.

In addition, the main demand of household refrigeration is refrigeration and energy saving effect, a small amount of frost does not affect much, and the frequency of household door opening is low, the temperature is stable and the noise is small.

2.matters need attention

We need to pay attention to the maintenance of beverage cabinets and the differences between different brands. The specific analysis is as follows:

1. Maintenance: Determine the “Life and Energy Efficiency” of Beverage Cabinets

The failure of beverage cabinets is mostly due to long-term neglect of maintenance, and the core maintenance points focus on “refrigeration efficiency” and “equipment wear and tear”.

（1）Basic cleaning (once a week)

Clean glass door stains (to avoid affecting the display), wipe the water in the cabinet (to prevent the cabinet from rusting), clean the condenser filter (dust will slow down the refrigeration and increase power consumption);

（2）Core component maintenance (once a month)

Check the door seal integrity (air leakage may reduce cooling efficiency by 30%; use a paper strip test —— if the paper strip cannot be pulled after closing the door, it is qualified), and inspect the compressor noise (abnormal noise may indicate poor heat dissipation, requiring cleaning of debris around the compressor).

（3）Long-term precautions

Avoid frequent door opening and closing (each opening increases cabinet temperature by 5-8℃, increasing compressor load), do not stack drinks beyond capacity (deformed shelves may compress internal pipes, causing refrigerant leakage), and do not force door opening during power outages (maintain low cabinet temperature to reduce food spoilage risk).

3. Brand differentiation: The key lies in “positioning and details”

Brand differentiation is not merely about price, but rather about “priority of demand” (such as pursuing cost-effectiveness, valuing durability, or requiring customized services). Common differences can be categorized into three types:
