Commercial refrigerator is an indispensable equipment in the catering, retail, supermarket and other industries. Its core function is to provide a stable low-temperature environment to store and display food, beverages and other commodities.
1. Classification of the main functions of commercial refrigerators
Classification by temperature requirements
Refrigerator (0~10℃): suitable for short-term storage of fruits and vegetables, dairy products, beverages, etc., inhibiting bacterial growth.
Freezer (below -18℃): used for long-term storage of meat, quick-frozen food, ice cream, etc., requiring rapid refrigeration and temperature stability.
Combination refrigerator: partition design, meeting the needs of refrigeration and freezing at the same time.
Classification by use
Display refrigerator: transparent glass door design, taking into account both product display and preservation (such as convenience store beverage cabinets, cake cabinets).
Storage refrigerator: large capacity, closed design, suitable for back kitchen or storage (such as restaurant food cold storage).
Smart refrigerator: equipped with Internet of Things technology, supports remote monitoring of temperature, energy consumption data, etc. (such as chain brand special equipment).
Special function refrigerator
Air curtain cabinet: open design, forming a "wind curtain" through cold air circulation to reduce cold air loss (commonly used in supermarket fresh food areas).
Wine cabinet: precise temperature control (10~18℃) and humidity control to avoid vibration interference and protect the quality of red wine.
Medical refrigerator: meets medical standards and is used to store vaccines, medicines, etc. (strict temperature recording and alarm functions are required).
2. Core design elements of commercial refrigerators
Material and structure
Box material: stainless steel (corrosion resistance, easy to clean), tempered glass (light transmittance, beautiful), environmentally friendly insulation layer (polyurethane foaming, reducing cold loss).
Door design: double door/multi-door independent switch, hollow glass door (anti-fogging), magnetic door seal (sealing).
Refrigeration system
Compressor type: fixed frequency (low cost but high energy consumption) vs. variable frequency (energy saving, low noise).
Refrigeration method: direct cooling (simple structure but regular defrosting required) vs. air cooling (frost-free design, uniform temperature).
Energy consumption and environmental protection
Commercial refrigerators are usually high-energy-consuming equipment, and attention should be paid to the energy efficiency level (such as China Energy Efficiency Label Level 1 is the best).
Environmentally friendly refrigerants: gradually phase out traditional Freon (R22) and adopt low-carbon refrigerants such as R290 (propane) and R600a (isobutane).
Space and humanized design
Adjustable shelves: adapt to different sizes of goods.
Lighting design: LED cold light source (energy-saving and does not generate additional heat).
Drainage system: bottom water guide groove design for easy cleaning.
Safety protection
Anti-fog glass: avoid fogging and affecting the display effect.
Power failure protection: automatic alarm or start backup power supply when temperature is abnormal.
Anti-leakage design: grounding protection, insulating materials.
