1. Small cold storage is generally divided into indoor type and outdoor type.

1.
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 storage cold storage: +5 ~ -5 ° C; cold storage cold storage: -5 ~ -20 ° C; low temperature cold storage: -25 ° C

3. Into the cold storage food temperature: L-class cold storage: +30 ° C; D-class, J-class cold storage: +15 ° C.

4. The
effective volume of the stacking cargo of the assembled cold storage equipment is about 69% of the nominal volume, and the correction factor of 0.8 is multiplied when storing fruits and vegetables.

5. The daily purchase volume is 8-10% of the effective volume of the cold storage.

Second, the small cold storage library

Small cold storage is generally made of spray-coated color steel plate, rigid polyurethane foam or high-density polystyrene as insulation material. The storage body has the characteristics of good rigidity, high strength, good thermal insulation performance and flame retardant. The small cold storage warehouse body generally adopts the eccentric hook connection or the on-site foaming and solidification of the embedded parts inside the slab wall, and the sealing property is convenient to assemble and disassemble, and the construction and installation on site is small, labor saving, good quality and quick effect. The small cold storage is equipped with advanced refrigeration unit, the storage capacity is matched with the refrigeration equipment, the cooling speed is fast, the energy saving is energy-saving, and all the automation operations are safe and reliable. The small assembly type cold storage is widely used. The cold storage temperature range is 5°C--23°C, and the special assembly type cold storage can reach below -30°C, which can meet the needs of different applications and is suitable for use in various sectors of various industries.

Third, the choice of small cold storage refrigeration equipment

The heart of the small cold storage refrigeration equipment is the
cold storage door unit. The common type of small refrigeration unit is equipped with advanced fluorine machine refrigeration equipment. The fluorine machine refrigeration equipment uses refrigerant R22 and other new refrigerants with little impact on the environment. Fluorine refrigeration equipment is generally small in size, low in noise, safe and reliable, high in automation, wide in scope of application, and suitable for small-scale cold storage refrigeration equipment in rural areas.

The combination of a small refrigerator and a
cold storage unit such as a condenser is often referred to as a refrigeration unit, and the refrigeration unit is divided into a water cooling unit and an air cooling unit. The small cold storage is the preferred form of air-cooled unit. It is simple, compact, easy to install, easy to operate, and has fewer auxiliary equipment. This kind of refrigeration equipment is also easy to see.

The chiller of the refrigeration unit is the heart of the refrigeration equipment. The common compression chillers are open, semi-closed and fully enclosed. The fully enclosed compressor is small in size, low in noise, low in power consumption, and energy efficient. It is the preferred model for small cold storage. Air-cooled refrigeration units consisting mainly of totally enclosed compressors can be made in the form of split air conditioners and mounted on the wall.

Nowadays, the closed-end refrigeration compressors on the market are relatively reliable. The quality of refrigeration equipment imported from developed countries or Sino-foreign joint ventures is relatively reliable, but the price is 50% higher than that of domestically produced machines. It is more suitable for small-scale cold storage refrigeration equipment in towns.

Fourth, small cold storage design points

The cold storage warehouse temperature is below 0 degrees (-16 degrees). The small assembly type cold storage requires 10# channel steel overhead on the ground (under the storage board) to make it naturally ventilated. Small cold storage, the temperature in the cold storage is 5~-25 degrees, and the
active cold storage board can be directly in contact with the ground, but the ground should be flat. If a high point is required, a wooden strip can be placed under the cold storage, overhead to enhance ventilation; or a channel can be placed under the cold storage to enhance ventilation.

V. Suggestions for design and installation of small cold storage projects

In recent years, the development of cold storage project construction is getting faster and faster, and everyone
's understanding of drug cold storage is getting deeper and deeper. The choice from building materials to various cold storage equipment is becoming more and more mature. There are two common construction methods for ice storage cold storage projects, one is the assembly type cold storage project, and the other is the civil construction cold storage project.

At present, the assembled
cold storage cold storage warehouse selects polyurethane storage body: the cold storage storage board is polyurethane rigid foam (PU) as the sandwich, and the metal material such as plastic coated steel plate is used as the surface layer, and the thermal insulation performance of the cold storage library material is superior. Combined with good mechanical strength. It has the characteristics of long thermal insulation, simple maintenance, low cost, high strength and light weight. It is one of the best materials for the selection of low temperature cold storage insulation board. The thickness of cold storage board is generally 150mm and 100mm. Most of the civil cold storage projects use PU polyurethane foam to make insulation boards.

The selection of refrigeration equipment for cold storage projects mostly uses Freon refrigeration units, large cold storage multi-cooling units, and small cold storage multi-purpose air-cooled units. Currently imported German Bitzer cold storage refrigeration units and French Meyou units, stable operation and low energy consumption, failure rate Low is the
preferred unit for refrigeration equipment .

It is important to pay attention to whether the refrigeration equipment of the cold storage project is properly configured. This is because the refrigeration unit with reasonable matching and reliable performance can meet the requirements of the cold storage capacity and cold storage process required by the product, save energy and low failure rate. Now some enterprises and individuals who want to build cold storages are blindly pursuing low prices, ignoring whether the cold storage equipment configuration matching is reasonable, resulting in failure to achieve refrigeration after use. Reasonable setting of matching cold storage projects to
assemble cold storage equipment, construction of cold storage may increase investment, but in the long run, it saves a lot of money and power.

The after-sales service of the refrigerator equipment is also very important, and the operation and maintenance of the cold storage equipment and technical services are equally important. The vast number of database construction enterprises should conduct various inspections before the construction of the cold storage, listen to other enterprises' opinions on the cold storage refrigeration equipment configuration, and finally determine the practical cold storage plan. Let yourself establish your own electric sliding door with high starting point and high standard , and strive for the best benefit for yourself.
