2. Maintain the optimum temperature of storage preservation of agricultural products
   As the temperature is in the season of the year and time of day changing, most of the conventional cultivation of agricultural harvest season, temperatures are high, and circadian amplitude is large, extremely inappropriate storage of fresh products. Many simple way is to find a natural temperature is relatively low and stable place for storage of agricultural products, to extend the shelf life of products, such as caves, crypts, shade, these methods can not arbitrarily control the temperature, and preservation of poor preservation period also short. Temperature according to the real long-term product freshness storage requirements, the ultimate solution is to rely on artificially produced a relatively stable low temperatures, namely by mechanical equipment and electronic devices, within a certain range, can artificially control the temperature, a variety of common cold , is one such facility.

3. What is cold
    Cold, generally refers to a variety of refrigeration equipment, can be artificially controlled and stable low-temperature facilities. Its basic components are: refrigeration systems; electronic control device; a certain insulation properties of the Treasury; subsidiary buildings.

    Refrigeration system includes a variety of refrigeration equipment, cold storage refrigeration equipment is the heart of it to create a cold, cold source to ensure the supply within the Treasury. Electric control device is cold brain, which command the refrigeration system to ensure supply of cooling capacity.

    Treasury has a certain insulation properties, is the storage place for the preservation of agricultural products, its role is to maintain a low temperature environment of stability, thermal insulation usually say insulation. Treasury good thermal insulation structure that can maximize their cold refrigeration equipment manufactured in small library leaked out, in turn, is to minimize the heat outside the library to library leak, which is the main cold storage houses and the general the difference.

4. Cold type and construction of rural origin choices
    More types of cold storage, classification lack of uniform standards. Press the origin of the type commonly used briefly as follows:
    (1) classification according to the size of storage capacity large, medium and small points. General information on the commercial terms of large and medium-sized libraries are too large capacity. According to the current cold country of origin are relatively small features as well as customary title of the masses, the storage capacity can be more than 1,000 tons of large-scale library called library, 1000 tons, 100 tons of medium-sized library called library of 100 tons library is called a small library. Origin village is best suited to build 10 tons to 100 tons of a small refrigerator.

    (2) by using a chiller refrigerant cooling mechanism can be divided into ammonia ammonia hangar fluorine and fluorine mechanism cold hangar, country of origin can be used to build a small cold high degree of automation fluorine hangar.

    (3) by low-temperature high and low temperature cold storage library and the library of high temperature points, fruit and vegetable preservation library is typically a high temperature library, the lowest temperature of -2 ℃. Aquatic, carnivorous cold storage library is low, the temperature below -18 ℃.

    (4) in the form of cold in the refrigerator dispenser with an exhaust pipe and cold refrigerator cooling fan. Fresh fruits and vegetables are generally cooler with cold, commonly known as the cold wind.

    (5) by the way into the Treasury building civil cold storage, cold storage and assembly complex civil assembly cold storage. Cold storage construction is generally a sandwich wall insulation, large area, long construction period, the early cold is this way. Assembly of prefabricated cold storage insulation board is fabricated of the Treasury, the short period of its construction work, removable, but the investment is large. Civil composite assembly cold storage, and peripheral load-bearing structure of the Treasury in the form of a civil, insulation in the form of spray foam polyurethane or polystyrene foam board assembly. Wherein polystyrene foam board insulation composite assembly of civil cold most affordable, is the origin of the construction of cold storage preferred form.

5. Small refrigerator suitable refrigeration equipment
    Cold storage cold storage refrigeration equipment is the heart of a very important, a cold running good and bad effects of the most critical conditions of refrigeration equipment.

    Refrigeration equipment refrigerator body is that it has a good variety, divided by the refrigerant and ammonia machine of fluorine machine two kinds. Some fluorine refrigerant machine is more common models, advanced fluorine machine utilization of low environmental impact of refrigerant R22 and other new refrigerants. Fluorine machines generally small size, low noise, safe and reliable, high degree of automation, wide application, suitable for rural small refrigerator use.

    Refrigerator with the condenser and other equipment together often referred to as refrigeration units, water-cooled chiller units and air-cooled unit points. Small refrigerator air-cooled unit as the preferred form, it has a simple, compact, easy to install, easy to operate, less ancillary equipment and so on.

    Refrigerator refrigeration unit is the heart of refrigeration equipment, common compression chiller with open, semi-closed and closed points. Hermetic compressors, small size, low noise, low power consumption, high efficiency and energy saving. It is the preferred model the vast number of small rural cold storage by hermetic compressors mainly composed of air-cooled chiller, can be made as split air-conditioning, as the form of the wall hung installation.

    Now the market is better closed refrigeration compressor developed to imports or joint venture product quality is reliable, but the price is high relative to more than 50% of domestic confidential.

6. Village built a small refrigerator benefits
    The most suitable rural origin to build 10 tons to 20 tons a small refrigerator, small refrigerator investment of 2 million to 4 million households are generally acceptable range. This small cold storage unit capacity is small, easy to control, easy out of storage, a product that is easy to fill the reservoir, cooling rapidly, temperature stability, low power consumption, high degree of automation, as household air conditioners and refrigerators as easy to manage. A plurality of such small refrigerator built together to form a small group of cold storage, with a total capacity of up to several hundred tons, thousands of tons of scale, its total investment in the same scale, similar to large cold storage. But it can more product freshness and variety, according to their different preservation temperature requirements, can be arbitrary control, respectively, which is a large-capacity refrigerator is not easy to do. All in all the flexibility of a small group of cold, operability, degree of automation, energy efficiency and operating results to be much better than medium and large cold storage.

Compared with the general system of cold storage, cold storage Andre has the following characteristics:
(1) Green, odor antibacterial, energy saving, low operating costs
(2) reliable, no maintenance worries, cooling speed, low noise
(3) the use of high-efficiency air-cooled or water-cooled condenser
(4) easy disassembly transport, installation period is short, small refrigerator 2-5 days to delivery.
