(Summary description)The factors of cold storage energy consumption mainly includes the performance of the refrigeration system, refrigerant selection, selection of compressor, condenser and evaporator, cold storage size and layout, type and thickness of the insulation layer of cold storage, cold storage times of the import and export of goods, cold storage door insulation performance, to improve the efficiency of cold storage refrigeration all factors should be taken into account.
The ways of reducing energy consumption in energy saving cold storage are usually divided into two parts: 1) reducing cold storage load of cold storage, and (2) selection of cold storage equipment.
A fruit and vegetable cold storage fruits and vegetables such mini cold storage refers to the base plate and a cold storage refrigeration system, evaporator in the factory prefabricated, installed at the site of origin of agricultural products after the cold or cold storage construction become the assembly or semi assembly semi cold storage construction, and storage capacity is generally less than 200m3, for the cold storage. According to the design temperature, the minitype cold storage of fruit thinning belongs to the high temperature cold storage. The miniature cold storage is composed of the refrigeration system, the storehouse and the control system.
The influence factors of energy consumption of the cold storage and cold storage of fruits and vegetables energy-saving measures
1. the cooling capacity of the cold storage structure is directly proportional to the unit heat flow of the enclosure structure. Therefore, more efforts should be made to reduce the unit heat flow index in the cold storage of cold storage. To reduce the unit heat flow of the envelope, one is that the thermal conductivity of the insulation material is small, and the two is the thickness of the enclosure structure. But the thickness is generally not too thick, otherwise it will increase the cost of construction and waste space and other problems. Therefore, the thermal insulation material should be selected within the appropriate thickness range. Usually, the thermal conductivity of the thermal insulation material is small, the water absorption rate is low, the low temperature resistance is good, and the cost can not be too high. The common cold storage materials are rice husk, polystyrene foam, polyurethane rigid foam, and so on. The rice husk is convenient, but the heat resistance is small, easy to absorb moisture, and a large amount of base construction, the time-consuming, cost is not lower than the polystyrene foamed polystyrene; many manufacturers, purchase convenient, affordable, build a larger thermal resistance, convenient installation; polyurethane rigid foam thermal resistance, thermal insulation performance is best, but the price is high.


2., the damp proof and steam isolation of the cold storage enclosure structure is also necessary for the cold storage enclosure structure to take moisture proof and steam isolation measures, otherwise the insulation performance of the insulation material will become worse. This is the reason that the thermal insulation performance of the cold storage tank is very good at the beginning of use, but the heat insulation effect is worse after a period of time. As the water vapor permeated from the side of the high temperature to the low temperature side, the moistureproof layer should be located on the side of the high temperature of the insulation layer.


3. the evaporation pressure of the cold storage and the evaporation temperature of the temperature are corresponding to the evaporation pressure. After the evaporation pressure is known, the evaporation temperature can be obtained by checking the table. Under the condition of certain temperature, the temperature difference (the difference between evaporative temperature and storehouse temperature) is reduced, and the evaporation temperature can be increased correspondingly. The refrigerating capacity of the refrigerator will be improved, that is, the circulation efficiency is increased, and the power consumption is correspondingly saved.


4. cold storage defrosting operation in general, when the frost on the evaporator surface layer of air resistance is not significant, yet reduce the air flow through the evaporator before the effect of frost is not serious, may not have to defrost; when the air flow was significantly reduced, should be defrosting. The air humidity is high temperature storage, evaporator temperature and cold storage is bigger, more easily in the evaporator frosting, combined with the preservation process, as far as possible the use of packaging can reduce the consumption of fruits and vegetables frozen dry, reduce evaporator defrosting times, actually also played the role of energy-saving refrigerator.

The factors of cold storage energy consumption mainly includes the performance of the refrigeration system, refrigerant selection, selection of compressor, condenser and evaporator, cold storage size and layout, type and thickness of the insulation layer of cold storage, cold storage times of the import and export of goods, cold storage door insulation performance, to improve the efficiency of cold storage refrigeration all factors should be taken into account.

According to the design temperature, the minitype cold storage of fruit thinning belongs to the high temperature cold storage. The miniature cold storage  is  composed of the refrigeration system, the storehouse and the control system.
The influence factors of energy consumption of the cold storage and cold storage of fruits and vegetables energy-saving measures
1. the cooling capacity of the cold storage structure is directly proportional to the unit heat flow of the enclosure structure. Therefore, more efforts should be made to reduce the unit heat flow index in the cold storage of cold storage.

2., the damp proof and steam isolation of the cold storage enclosure structure is also necessary for the cold storage enclosure structure to take moisture proof and steam isolation measures, otherwise the insulation performance of the insulation material will become worse. This is the reason that the thermal insulation performance of the cold storage tank is very good at the beginning of use, but the heat insulation effect is worse after a period of time.

5. the storage temperature of the cold storage and the storage temperature of the fruits and vegetables with different utilization ratio in the cold storeroom are different, and each kind of fruit and vegetable also has the temperature range suitable for its storage. In the case of not affecting the quality of fruit and vegetable, the high storage temperature should be selected for the energy saving cold storage. The cold temperature is high, the evaporation temperature of refrigeration system is also improved, the refrigerating capacity of refrigerator will be increased, it certainly improves the circulation efficiency. Improve the refrigerator temperature but also can reduce the heat transferred outwards through the library. The utilization ratio of the energy saving cold storeroom is the ratio of the volume of fruit and vegetable to the effective volume of the storeroom. The volume utilization ratio of the miniature refrigeratory is generally not less than 0.3, of course, it can not be too high, otherwise the cooling is difficult. When the volume of the fruits and vegetables to be stored is large, it should be separated into two or more cold storage rooms. In addition, we should choose a reasonable storage cycle, which is self-evident to the energy saving of the cold storage.
 
 
Two, frequency conversion technology is used for energy saving in cold storage. In view of the 80% of the electricity consumption of refrigerated storage and refrigerating enterprises, the power consumption of the compressor is about 60%, so the energy saving of the matching motor of the compressor is more significant. Cold storage design, to determine the general assembly machine according to the maximum mechanical load the year, in order to meet the requirements of the peak heat load but in actual operation, due to the existence of food cold processing and other factors, often cold compressor design matching full load operation time is short, low load operation time is long, so that most of the compressor time is less than the design load operation conditions, in our country, widely exists in the low load refrigerator compressor motor.
 
 
Three, mini cold storage of mini cold storage is at present in our country the main agricultural production management mode and rural family economic and technical level, the development of a simple operation, reliable performance, good storage facilities, has won the national patent and eighth Chinese patent new products and Technology Expo
