The cooling principle of fruit air curtain cabinets is to use cold air blown out from the top and back, with air returning to the bottom. This ensures that the cold air circulates internally, preventing loss of air and evenly covering every corner of the fruit air curtain cabinet, preserving the freshness of the produce. So why do some air curtain cabinets consume so much power?

1. The higher the ambient operating temperature, the greater the power consumption. The operating temperature is directly related to the power consumption of the air curtain cabinet. A high ambient operating temperature reduces the cabinet's heat dissipation efficiency, slowing the cooling process, resulting in longer operating times and increased power consumption.

2. The temperature itself is problematic. Air curtain cabinets have a temperature control switch, and improper temperature settings can also increase power consumption. This is because refrigeration temperatures are much higher than freezing temperatures. Higher temperatures make cooling easier. However, lower temperatures increase the demand for cooling, resulting in higher power consumption.

3. Reduce door openings. When you open a fruit cabinet for a moment, you'll notice a drop in temperature. This is because the cold air inside the cabinet needs to be exhausted. The temperature of the cold air inside the cabinet rises after it is exhausted. If the temperature does not reach the set point, the compressor will continue to run, increasing power consumption.

4. Defrost promptly. Frost and ice will not pass through the cold air. If frost or small ice particles appear on the air curtain cabinet, they must be addressed promptly to avoid increasing the compressor's operating time and power consumption.
