The specific embodiment
Fig. 1 is the structure chart of air conditioner with oxygen enrichment device of embodiment of the present invention.The connecting line (not illustrating among the figure) that air conditioner has indoor set 11, off-premises station 1 and is connected them and refrigerating gas is circulated.Indoor set 11 has the fan 13 as pressure fan.Off-premises station 1 has compressor 20, heat exchanger 22, fan 21 and is installed in oxygen enrichment device 30 in another zone.
Air after oxygen concentration improves is responsible for 6 by discharging, and sends in the indoor set 11.In the framework of indoor set 11 inner or its near, be provided with the outlet 7 of blow out air.In the indoor set 11 of outlet 7 with the air-supply loop configuration in the framework, will be added on from the air of outlet 7 outputs the air-supply that fan 13 blows out, send into the space of conditioned air from blow-off outlet 14 again.
Here, about the formation and the action of the freeze cycle of air conditioner, because of irrelevant with the present invention, its detailed description of Therefore, omited.
Secondly, utilize Fig. 1-Fig. 3 that the work of the oxygen enrichment device of said structure is described.Fig. 2 represents the control method of the oxygen enrichment device of present embodiment.Fig. 3 is the sequential chart of the oxygen enrichment device work of expression present embodiment.
When drawdown pump 3 runnings, by the air shown in the arrow 15a of oxygen enrichment mechanism 2, be responsible for 4 by oxygen supply, be depressurized pump 3 and suck, the air after oxygen concentration improves then is responsible for 6 by discharging, and delivers to indoor set 11.The running ability of drawdown pump 3, promptly the air output of time per unit is variable.
When drawdown pump 3 running, the temperature of the ambient atmos that control device 12 will be detected by temperature sensor 10 compares with predefined temperature T 1 and T2, according to control method shown in Figure 2, as shown in Figure 3, the running ability of control drawdown pump 3.
In Fig. 2, the ambient atmos temperature height that the top is detected, more downwards, then the temperature of ambient atmos reduces.At first, under the situation of temperature high temperature T a than design temperature T1 of the ambient atmos that detects, the running ability of control part 12 control drawdown pumps 3 turns round comprising under the running ability lower than ultimate operational capability.Reduce at extraneous gas temperature, under the situation of the temperature T b lower than design temperature T1, because the running ability of drawdown pump 3 reduces, the possibility that the water that produces in the dewfall of discharging on the person in charge 6 freezes is big.Therefore, control section 12 turns round drawdown pump 3 under its ultimate operational capability, water is not freezed, and discharges from outlet 7.
