Operation principle of the present utility model as shown in Figure 1, oxygen-enriching device A discharges the power of the rich nitrogen B of high pressure as pneumatic refrigeration compressor D, E regulates the room temperature by refrigerating plant.The isolated low pressure oxygen rich air of oxygen-enriching device A C can be used as oxygen rich source and is directly used in oxygen content in the conditioning chamber.The rich nitrogen F of low pressure that is discharged by rich nitrogen B of high pressure or pneumatic refrigeration compressor D can directly send into nitrogen preservation cabinet G and use.

Fig. 2 is the utility model one embodiment, and it utilizes transformation absorption carbon molecular sieve gas separation, and air separation is become nitrogen and oxygen.Oxygen (being oxygen rich gas) enters indoor, and the room air oxygen content is increased, and nitrogen (gases at high pressure) is used for driving pneumatic refrigeration compressor, forms pneumatic air-conditioning system.The low-pressure nitrogen of discharging enters and carries out food fresh keeping in the nitrogen preservation cabinet, is discharged in the outside atmosphere by antistaling cabinet at last.Specifically, the utility model is by air compressor machine (1), Pressure gauge (2), filter (3), middle envelope formula 3 position-5 way magnetic valve (4), adsorbing cylinder (5), (6), blowback control valve (7), center-leakage type 3 position-5 way magnetic valve (8), flow control valve (9), oxygen content control valve (13), muffler (14) are formed the oxygen enricher system, air compressor machine (1) sucks room air, behind oxygen enricher, oxygen rich gas enters indoor by muffler (14), when indoor oxygen content reaches setting value, control valve (13) commutation, oxygen rich gas is arranged to outdoor.Nitrogen pressure (0.5Mpa) enters pneumatic type air-conditioning system or nitrogen preservation cabinet by control valve (9), and pneumatic air-conditioning system is made up of reversal valve (10), pulse valve (11), pneumatic type refrigeration compressor (12), safety valve (15), condenser (16), ventilating fan (17), capillary (18), evaporimeter (19), centrifuge (20), the warm switching valve (23) of refrigeration/system.The nitrogen preservation cabinet is made up of antistaling cabinet (21), evaporimeter (22).

Its course of work is as follows: indoor fresh air is compressed to the Compressed Gas [being shown by Pressure gauge (2)] of 0.8 MPa through air compressor machine (1), through entering transformation absorption oxygen-enriching device behind filter (3) the filtering mist of oil, this device mainly utilizes carbon molecular sieve to have oxygen molecule is adsorbed when the high pressure, the characteristic of desorb during low pressure, making air separation is nitrogen and oxygen, is used.Its process is as follows, when central envelope formula 3 position-5 way magnetic valve (4) and center-leakage type 3 position-5 way magnetic valve (8) all are positioned at left chamber state, compressed air enters adsorbing cylinder (5) by valve (4), carbon molecular sieve adsorb oxygen molecule nitrogen molecular in the adsorbing cylinder (5) then enters air-conditioning system or nitrogen preservation cabinet by valve (8) and control valve (9), adsorbing cylinder (6) is owing to the path with valve (8) is in closed state, and with valve (4), path is in opening state, again oxygen content control valve (13) is in opening state, then adsorbing cylinder (6) is in the low pressure desorption state.Formerly be adsorbed on oxygen molecule on the carbon molecular sieve by desorb, reduction and the next blowback nitrogen formation oxygen rich gas of a small gangs of process blowback control valve (7) with pressure enter indoor through muffler (14), the pure content of indoor oxygen is increased, indoor oxygen content was above 40% o'clock, commutate by electronics oxygen analyser system control valve (13), oxygen rich gas is discharged to outdoor, valve (4) and valve (8) state that all mediates then, between adsorbing cylinder (5) and (6) by the outside UNICOM of valve (8), carry out the high and low pressure balance, valve (4) and valve (8) all commutate and are in right chamber state then.Adsorbing cylinder (6) pressurization absorption, adsorbing cylinder (5) decompression desorb, the course of work is the same, so circulation.The nitrogen of being discharged by the oxygen enricher system is that thick nitrogen (nitrogen content is 98%) pressure is 0.5Mpa.High pressure nitrogen enters reversal valve (10) by flow control valve (9), when reversal valve (10) is in left chamber state, nitrogen enters air-conditioning system, air-conditioning work, high pressure nitrogen drives pneumatic refrigeration compressor (12) by pulse valve (11) and moves back and forth the compression work of carrying out cold-producing medium, the low-pressure nitrogen of being discharged by pulse valve (11) blows to evaporimeter (22) in the antistaling cabinet (21) after cooling, enters fresh-keeping chamber, discharges outdoor then.Make to be full of low temperature nitrogen in the antistaling cabinet, fresh keeping time and effect can be more far better than simple deepfreeze refrigerator in low temperature nitrogen for various food, vegetables, fruit, meat etc.The pneumatic type refrigeration compressor utilizes high pressure nitrogen for power, with after the refrigerant compression, lean on fan (17) air-cooled (or by water-cooled) through condenser (16), behind the condensation liquefaction,, enter the indoor evaporator (19) and the antistaling cabinet evaporimeter (22) of air-conditioner by capillary (18) decompression.Centrifuge (20) through evaporimeter (19) circulation cooling, is regulated indoor temperature with room air, and evaporimeter (22) then is used for cooling off the nitrogen that enters in the antistaling cabinet (21).Cold-producing medium after the evaporation is compressed by pneumatic refrigeration compressor more again, enters recirculation.When room temperature reached needed temperature, reversal valve (10) commutation was in right chamber state, and nitrogen enters in the antistaling cabinet after decompression, and air-conditioning is quit work.The filter of air-conditioning part, control device is identical with former air-conditioning technical, the working cycles automatic control system of oxygen enricher and the test control system of indoor oxygen content are realized by electrical system, can be when winter by warm switching valve (23) commutation of refrigeration/system, condenser (16) becomes evaporimeter, evaporimeter (19) becomes condenser and realizes conversion, and it is warm that room air conditioner begins system.Evaporimeter (22) still is an evaporimeter, and keeping in the cabinet is low temperature.

Both the utility model has the advantages that and the interior temperature of conditioning chamber to use as air-conditioner, again could Increase the content of oxygen in the room air, build one to the very favorable oxygen enrichment of people space, stopped The generation of air conditioner disease. Simultaneously, isolated nitrogen can also be used to fresh-keeping fruit, food, vegetables etc. Be not suitable for the thing of freeze preservation. In the antistaling cabinet of Ultra Low-oxygen or anaerobic, freezing bar can not needed Under the part, keep the fresh of article, and the original nutrition of not broken ring. The utility model is simple in structure, Easy to manufacture, cost is also cheaper, and consumers in general are easy to accept.
