Abstract
The utility model relates to an air-conditioning fresh-keeping refrigerator. The air separation device comprising air compressor, sterilizing filter, nitrogen-oxygen membrane separator or pressure swing adsorption separator and the refrigerating device comprising refrigerant compressor, condenser, evaporator, cold storage chamber or freezing chamber and humidifier constitute one kind of air conditioning and fresh keeping refrigerator with air separation device inlet and cold storage chamber or freezing chamber outlet connected together via pipeline. The refrigerator has effects of regulating aseptic component gas, keeping food fresh, and prolonging storage period.
Description
The utility model relates to a kind of refrigerator.
In practical refrigerator, give food with cold by transfer of air by refrigerating plant earlier usually, make food be cooled to refrigeration or cryogenic temperature, realize the purpose of storage.Because oxygen content is higher in the air, and spread germs, microorganism, food can produce brown stain, rot at duration of storage, and storage period is shortened.
The purpose of this utility model is to provide a kind of controlled atmosphere formula refrigerator.This refrigerator is isolated the nitrogen component gas more earlier with airborne bacterium, microorganism filtering, by refrigerating chamber in the refrigerating plant or refrigerating chamber circulation, to food fresh keeping, guarantee the quality, prolong storage period.
The utility model is to realize so in conjunction with the accompanying drawings.The refrigerating plant that the air separation unit of being made up of air compressor machine 1, sterilizing filter 2, nitrogen oxygen film separator (film group) or transformation adsorbing separation device (PSA) 3 and cold medium compressor 4, condenser 5, evaporimeter 6, refrigerating chamber or refrigerating chamber 7, humidifier 8 are formed, with refrigerating chamber or refrigerating chamber outlet in the inlet of air separation unit and the refrigerating plant, refrigerating chamber or refrigerating chamber enter the mouth and fuse respectively in the outlet of air separation unit and the refrigerating plant by pipeline.
According to said apparatus, with refrigerating chamber or freezing room air through the air compressor machine 0.6Mpa that boosts, by the sterilizing filter degerming, through nitrogen oxygen film separator or transformation adsorbing separation device, air separation is adjusted in nitrogen 98%, oxygen 2%, carbon dioxide 3% component gas, step-down 0.04Mpa gets back to refrigerating chamber or refrigerating chamber, the refrigerating plant of being made up of cold medium compressor, condenser, evaporimeter, refrigerating chamber or refrigerating chamber, humidifier simultaneously provides cold, make the interior food of refrigerating chamber or refrigerating chamber be cooled to 0 ℃, humidifier humidification to 90%.Realization to food fresh keeping, the purpose of guaranteeing the quality, prolonging storage period.
Description of drawings:
A kind of controlled atmosphere formula of Fig. 1 refrigerator
Embodiment: 1, with total dischargeable capacity 100L, 2 the direct-cooled controlled atmosphere formula refrigerators in Room 2 are example, and its important technological parameters design is as follows:
Air separation unit is selected the nitrogen oxygen film separator for use, controlled atmosphere component nitrogen 98%, oxygen 2%, carbon dioxide 3%, discharge rate 3L/min.Power consumption 0.06kw.h/24h.
In the refrigerating plant, one of refrigerating chamber 50L, 0 ℃ of temperature, humidity 90%.One of refrigerating chamber 50L, temperature-10 ℃.Power consumption 0.20kw.h/24h.
100L controlled atmosphere formula refrigerator total power consumption 0.26kw.h/24h.
With refrigerating chamber, refrigerating chamber outlet in air separation unit inlet and the refrigerating plant, refrigerating chamber, refrigerating chamber inlet fuse respectively in air separation unit outlet and the refrigerating plant by pipeline.
