Subtitle: A Must-Have Cooling Equipment for Stores & Supermarkets
Overview: Air curtain cabinets, also known as vertical open refrigerators, are widely used in supermarkets, convenience stores and catering places. They combine display and refrigeration, keeping food fresh while allowing customers to take items easily. This blog introduces its structure, working principle and practical advantages, within 500 words.
Key Structure of Air Curtain Cabinets
Its core structure consists of five parts: cabinet body, refrigeration system, air curtain system, display layer and temperature control system. The cabinet body is made of heat-insulating materials to reduce cold loss. The refrigeration system includes compressor and evaporator, responsible for cold air generation. The air curtain system (built-in fan and air outlet) forms an invisible air barrier.
Working Principle
1. Cold Air Generation: The compressor compresses the refrigerant, which turns into low-temperature liquid after heat release, and then flows into the evaporator to absorb heat and form cold air.
2. Air Curtain Formation: The built-in fan blows the cold air out from the top air outlet, forming a dense cold air curtain at the cabinet opening, isolating the internal cold air from the external hot air.
3. Constant Temperature Maintenance: The temperature control system monitors the internal temperature in real time. When the temperature rises, the refrigeration and air curtain systems start working to keep the temperature stable (usually 2-8℃).
With open design and efficient refrigeration, it balances display effect and fresh-keeping performance, becoming an essential equipment for commercial places to attract customers and preserve food.
