The small refrigerators designed by the quick-freezing company are generally divided into indoor and outdoor types: 1. The ambient temperature and humidity outside the cold storage: the temperature is + 35 ° C; the relative humidity is 80%. 2. Set temperature in the cold storage: fresh-keeping cold storage: + 5 ～ -5 ℃; refrigerated cold storage: -5 ～ -20 ℃; low-temperature cold storage: -25 ℃ 3. Food temperature in the cold storage: L-level cold storage: + 30 ℃; Grade J and Grade J cold storage: + 15 ℃. 4. The effective volume of the stacked cold storage is about 69% of the nominal volume. When storing fruits and vegetables, multiply the correction factor by 0.8. 5. The daily purchase volume is 8-10% of the effective volume of the cold storage.
Small-scale quick-freezing cold storage generally uses spray-painted color steel plate as the panel, and rigid polyurethane foam or high-density polystyrene as the insulation material. The storage body has the characteristics of good rigidity, high strength, good heat insulation performance, and flame retardancy. Small-scale cold storage warehouses generally use eccentric hook-type connection of embedded parts inside the wall or on-site foam consolidation, good sealing, easy assembly and disassembly and transportation, small amount of construction and installation work on site, labor saving, good quality and quick results. The small-scale cold storage is equipped with advanced refrigeration units. The storage capacity and cooling equipment are fully matched, the cooling speed is fast, power saving and energy saving, and all automatic operation is safe and reliable.
The development of cold storage engineering
is getting faster and faster, and everyone's understanding of cold storage is getting deeper and deeper. The choice from building materials to various cold storage equipment is becoming more and more mature. Small refrigerators are favored by many people due to their small size and easy management. The scope of use is also getting wider and wider, and the small-scale cold storage structure is divided into indoor and outdoor types. The small assembled cold storage is widely used. The temperature range of the cold storage is 5 ℃ --23 ℃. The special assembled cold storage can reach below -30 ℃, which can meet the needs of different uses and is suitable for various sectors and industries. Small-sized cold storage, the temperature in the cold storage is 5 ~ -25 degrees, the cold storage storage board can directly contact the ground, but the ground must be flat.
If a higher point is required, wooden bars can be placed under the cold room to increase ventilation; channel steel can also be placed under the cold room to enhance ventilation.
The heart of the cold storage equipment is the refrigeration unit. The combination of the refrigerator and the condenser is often referred to as the refrigeration unit. The common models of small refrigeration units are generally advanced fluorine refrigeration equipment. The fluorine refrigeration equipment is generally small in size and low in noise. , Safe and reliable, high degree of automation, wide range of applications, suitable for small refrigeration equipment in rural cold storage. For assembly cold storage, many choices of polyurethane storage body: that is, the cold storage board is made of polyurethane rigid foam (PU) as a sandwich, and metal materials such as plastic-coated steel are used as the surface layer. The superior thermal insulation performance and good Mechanical strength is combined. It has the characteristics of long thermal insulation life, simple maintenance, low cost and high strength and lightness. It is one of the best materials for cold storage insulation board selection. The thickness of cold storage board is generally 150mm and 100mm. Most of the civil cold storage projects use PU polyurethane foam to make thermal insulation storage boards. Whether the cold storage refrigeration equipment is properly configured is very important.
