There are two ways to implement refrigeration in the refrigeration and purification area 9 of the first air duct, taking a refrigerator as an example:
first, the original refrigeration cycle of the refrigerator is divided into a refrigerant flow through the second condenser 3 and the throttling structure 5, the refrigerant is throttled, a part of the refrigerant enters the refrigerating purification area 9 through the refrigerator inlet 81 of the purification device to be purified, the refrigerant in the refrigerating purification area 8 is evaporated to absorb heat, the refrigerating purification area 9 reaches the required low temperature, and the refrigerant returns to the original refrigeration cycle of the refrigerator again through the refrigerator outlet 82 after the refrigerant is evaporated.
Second, the refrigerant is obtained from the refrigerating chamber (at the first evaporator 6) or the freezing chamber (at the second evaporator 7) of the refrigerator, which in the present embodiment can be obtained from the freezing chamber; directly enters the refrigerator 8 through the refrigerator inlet 81, so that the low-temperature environment of the refrigeration and purification area 9 is realized, and after the refrigerant entering the refrigerator 8 exchanges heat, the refrigerant returns to the original refrigeration cycle of the refrigerator through the refrigerator outlet. As shown in fig. 1, the refrigerator 8 of the freeze purification section 9 has a communication relationship with the second evaporator 7 of the refrigerator, through which the refrigerant can be returned to the refrigeration cycle of the refrigerator.
The air which is subjected to primary purification through the freezing and purifying zone 9 is subjected to secondary purification through the filtering device 12, and then the air enters the energy-saving heat exchange zone 10; the cold in the purified cryogenic gas is recovered at the first condenser 2. The first condenser 2 may also take the form of other heat exchangers.
In the economizer heat exchange zone 10, the refrigerant flowing through the first evaporator 6 or the second evaporator 7 and the refrigerator 8 has higher heat energy due to heat absorption, and part or all of the refrigerant enters the first condenser 2 through the first condenser inlet 21; after exchanging heat with the low temperature gas purified in the economizer heat exchange zone 10, the refrigerant flows back to the refrigeration cycle of the refrigerator through the first condenser outlet 22. As shown in fig. 1, the first condenser 2 has a communication relationship with the first evaporator 6 of the refrigerator, through which the refrigerant can realize a refrigeration cycle back to the refrigerator.
The purified and heat-exchanged gas is discharged to the external space of the refrigerator through the air outlet 112; therefore, air is continuously purified, and air purification of the whole refrigerator external space is completed.
