The air-conditioning cold storage is based on the increase of gas composition in the cold storage. By controlling the temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, the respiration and self-consumption of fruits and vegetables are reduced to reduce the water loss. Reducing the occurrence of diseases and delaying its metabolic process, so as to maintain the texture, color, taste and nutrition of the storage materials for a long period of time, to maintain the freshness of fruits and vegetables, and to extend the storage period of fruits and vegetables, the most common use in the world is currently the best. One of the most advanced storage and preservation technologies
The traditional method of storage and preservation of fruits and vegetables has simple storage, ventilation storage, radiation preservation, chemical preservation, cold storage, fresh storage, simple storage, ventilation storage, simple storage, low storage, but poor storage. Short storage time, short decay, severe radiation and chemical preservation. Sexual but there are radiation and chemical residual pollution. Not all the fruits can be used. The modified atmosphere can be used to create the optimal environment for the storage of fruits and vegetables by changing the relative temperature of the gas components under the appropriate low temperature conditions. The effect is as follows: Hypoxia (usually 02 content of 1% 5%) The appropriate CO2 concentration can effectively inhibit the respiration and reduce the loss of nutrients in fruits and vegetables while inhibiting the growth and reproduction of pathogenic bacteria to control the occurrence of certain physiological diseases. In order to inhibit the ripening effect of fruits and vegetables, the relative humidity in the ambient gas is increased to reduce the transpiration of fruits and vegetables, thereby achieving the purpose of long-term storage and preservation of fruits and vegetables.
The air conditioning library is generally composed of a pressure balance system of the air conditioning system air conditioning system refrigeration system humidification system and temperature and humidity, 02.Co2 gas automatic detection and control system
Inhibition of respiration reduces the consumption of organic matter and maintains the excellent flavor and aroma of fruits and vegetables
Inhibit water evaporation to maintain freshness of fruits and vegetables
Inhibit the breeding of pathogenic bacteria, control the occurrence of certain physiological diseases, reduce the rate of fruit decay
Inhibition of certain post-mature enzyme activities inhibits ethylene production delays Post-ripening and senescence processes maintain long-term fruit firmness for a long shelf life
To make the air-conditioned storage reach theand maintain the relative stable， it is required to equip es apart from the airtight storage that meets with em，carbon dioxide deprivation system，ethylene defection and control system.
After the barrel pump unit is used, the gas return to the gas in the barrel is realized, and the working medium entering the compressor is realized as a dry gas to avoid the possibility of the compressor running on the wet stroke.
The use of a fluorine pump to force the liquid supply method to multiply the full liquid supply due to the increase in the flow rate of the liquid supply in the evaporator, so that the cooling efficiency of the evaporator is improved, thereby improving the heat exchange effect of the through-type equipment. The heat exchange (gas superheated liquid is too cold) has achieved the effect of double bottom, which effectively solves the oil return problem of the compressor fluorine system.
The barrel pump unit is equipped with an automatic manual oil return system in the heat exchanger of the oil university and returns to the compressor to effectively solve the oil return problem of the compressor fluorine system and improve the reliability of the system operation.
