Air curtain cooler introduction

The windscreen cooler is commonly used in large supermarkets, KTVs, and fruit shops for storing KTV beers and imported fruits in supermarkets. It offers excellent display, luxury, and convenience for customers to select their choices.

The air curtain cooler, also known as a vertical air curtain, operates by blowing cool air from the back, evenly covering every corner of the cooler to achieve product preservation.

The normal temperature setting for the windscreen cabinet is between 2~8 degrees Celsius. It is primarily used in supermarkets for storing beverages, yogurt, milk, vacuum-packed meats, ready-to-eat foods, fruits, etc., and is not suitable for unpackaged food items.

The windscreen cabinet is available in two models: built-in and external. The built-in model's advantages include ease of movement, but its drawback is noise (similar to the noise level of a residential air conditioner's outdoor unit). It is suitable for small supermarkets, convenience stores, fruit chain stores, etc. The external model's advantages are its low noise level, the ability to be extended in length, and its overall aesthetic and generous appearance.

Drawbacks: Not convenient for mobility and repair. Suitable for large supermarkets, hotels, etc.

The energy consumption issue of wind curtain cabinets: Under normal use, a wind curtain cabinet consumes approximately 8 to 9 degrees of electricity every 24 hours.

Commercial customers new to purchasing windscreen cabinets often have many uncertainties and misconceptions about the selection process.

Firstly, the price of wind curtain cabinets: the higher the price, the better the quality. In fact, whether it's when selecting wind curtain cabinet products or other products, there is often this thought: the higher the price of the product, the better it must be. However, this is not necessarily true. When purchasing cold cabinet products, customers should consider technical parameters and quality factors more than price. For instance, consider the preservation performance of the refrigerator, the convenience of storing food in the freezer, and whether the temperature control is ideal.

Common preservation technologies used in the wind curtain cabinet market include sterilization preservation, high humidity preservation, and ice temperature preservation. Bacteria, molds, and other microorganisms are the causes of food spoilage. By addressing the impact of these microorganisms on food, the main issue of food preservation is resolved. For vegetable preservation cabinets, preservation is achieved by treating the microorganisms on the food surface with gas sterilization technology, ensuring the freshness of the stored food in the cabinet.

Vegetable preservation involves storing food close to its freezing point. As the use of wind curtain cabinets becomes widespread, more attention is being paid to their maintenance. However, incorrect maintenance methods often lead to a decline in the performance of the refrigerators. Today, Yuanlong will educate you on proper maintenance of wind curtain cabinets. 1. When wiping the cabinet, use cotton towels or fabrics with good absorbency. Avoid using rough fabrics, threads, or buttons. Do not use dry cloths to wipe the surface dust, as dust is composed of fibers and sand. When dry cloths are used to wipe, these fine particles will repeatedly rub against the cabinet surface, potentially damaging the Zhejiang fruit wind curtain cabinet. The moisture content of the cloth should not be excessive, as too much water can渗透 into the wood, causing the surface material to mildew and deform, thus reducing the lifespan of the cabinet. 2. Properly arrange the preserved dishes; more is not always better. Only fill 80% of the cabinet with dishes. 3. Lowering the temperature is not always the best solution; adjust the temperature controller based on the current conditions. This is more energy-efficient and provides better preservation effects.

Why the Windscreen Cooler Is Not Cooling

1. Incorrect adjustment of the expansion valve and liquid outlet valve in the supermarket curtain cabinet cooler, excessive refrigerant in the system, air in the refrigeration system, poor sealing of the valve plate assembly, and wear on the compressor cylinder sleeve piston. 2. Breakage of the high-pressure output buffer pipe inside the compressor, or loosening of the screws securing it, causing the high-pressure pipe to not exhaust and the low-pressure pipe to not intake, thus the compressor operates but does not cool. 3. Leakage in the refrigeration system, with all the refrigerant escaping, although the compressor runs, there is no refrigerant evaporation and heat absorption in the system, so the temperature inside the refrigerator does not drop. 4. Blockage in the capillary tube, preventing refrigerant from entering the evaporator to evaporate and absorb heat, resulting in the temperature inside the refrigerator not decreasing. 5. Due to improper welding or use, the supermarket curtain cabinet cooler has a leakage point in the refrigeration system, and if all the refrigerant in the system leaks out within a certain period, the cooler will not cool. 6. Check if the usage setting of the supermarket curtain cabinet cooler is correct, as different settings affect the power consumption and temperature of the cooler.
