Specific embodiment
Present invention is further described in detail in the following with reference to the drawings and specific embodiments, but not as to limit of the invention
It is fixed.
As shown in Figure 1, the new energy air-conditioning includes: photovoltaic cell the embodiment of the invention provides a kind of new energy air-conditioning
Component 10, air conditioner 20 and photovoltaic lightningproof confluence component 30.Air conditioner 20 includes air-conditioner shell and is placed in air-conditioner shell
Air conditioner unit, above-mentioned photovoltaic cell component 10 connect with air conditioner unit.The above-mentioned photovoltaic lightningproof confluence setting of component 30 exists
In air-conditioner shell, photovoltaic lightningproof confluence component 30 is connect with photovoltaic cell component 10.Photovoltaic lightningproof in the embodiment of the present invention
Confluence component 30 is placed in the electrical appliance kit in air conditioner 20.
It is in the prior art relatively high to the degree of protection of photovoltaic lightningproof header box, reach the requirement of IP65 easily, not only
Want dust-proof, and there are also the anti-abilities in any direction sprayed water, it usually needs individually designed, die sinking, higher cost.The present invention is real
It applies in example and photovoltaic lightningproof confluence component 30 is arranged in air-conditioner shell, compared with the prior art, it is possible to reduce the prior art
In photovoltaic lightningproof header box, can be avoided photovoltaic lightningproof header box bring additional floor space, save the cost is not necessarily to simultaneously
The installation fixed form for considering photovoltaic lightningproof header box achievees the purpose that shorten construction period, saves engineering late maintenance cost.
Photovoltaic lightningproof confluence component 30 in the embodiment of the present invention is made of anti-backflow diode 31 and lightning protection device 32.This is anti-
Counter-current diode 31 is arranged on the positive line of photovoltaic cell component 10, and lightning protection device 32 is in parallel with photovoltaic cell component 10 to be set
It sets.Since photovoltaic cell component 10 is directly accessed the bus of air conditioner unit in the embodiment of the present invention, in night photovoltaic cell group
When part 10 does not generate electricity and air conditioner unit is in standby, the bus of air conditioner unit still with the presence of high pressure, if the high pressure after
The continuous both ends for being applied to photovoltaic cell component 10 will cause the decaying of photovoltaic cell component 10, and multichannel photovoltaic also will cause not when accessing
Degree of the crossfire to accelerate it to decay between going the same way, it is therefore necessary to increase anti-backflow diode 31 in photovoltaic access and avoid
The generation of the phenomenon.Simultaneously as photovoltaic cell component 10 is generally mounted to roof, easily pass through photovoltaic cell in thunderstorm weather
The electrical appliance kit that surge voltage introduces air conditioner 20 is caused device failure by the power supply line of component, it is therefore necessary to be let out by lightning protection device 32
Unrestrained energy when gushing is to avoid the influence of lightning stroke.
The components such as fuse, Mini-type direct current break are provided in photovoltaic lightningproof header box in the prior art, due to upper
The expensive of the components such as fuse, Mini-type direct current break is stated, the 40% of entire header box cost is accounted for, causes entire photovoltaic anti-
The cost price of thunder header box is higher.And the embodiment of the present invention makes full use of each component in air conditioner 20 that this kind of price is omitted
Expensive device, therefore the initial investment of engineering can be reduced.
Secondly as needing to concatenate anti-backflow diode in photovoltaic lightningproof header box in the prior art, and the companion often that works
There is thermal losses, therefore radiator need to be attached in photovoltaic lightningproof header box, while requiring for photovoltaic lightningproof header box to be installed on logical
The better place of wind.And anti-backflow diode 31 is placed in air conditioner electrical box by the embodiment of the present invention, it can be by sky
It adjusts the air blast cooling of itself to radiate, not only omit radiator but also can avoid improper ventilation bring integrity problem.
Again, the controller power supply in photovoltaic lightningproof header box in the prior art is usually provided by photovoltaic panel, is increased
Additional stand-by power consumption.And the embodiment of the present invention can improve system effectiveness indirectly after photovoltaic lightningproof header box is omitted.
Finally, photovoltaic lightningproof header box busbar short-circuit failure not only includes positive and negative anodes mother's short-circuit between conductors in the prior art,
Including branch switch connecting terminal to the line between bus and the short trouble on any point.When such accident occurs,
Fuse in the prior art performs practically no function.Because the direct current energy that sunlight is sent out is different from common AC network, alternating current
The capacity that net has near endless big does backing, is capable of providing powerful short circuit current, and solar panel can only provide immediately
The electric energy for impinging upon the conversion of its part above solar energy only turns a part of received solar energy without any energy storage
It changes electric energy into send out immediately, and internal resistance is again big.Therefore, normal condition, short-circuit conditions, short circuit current is substantially without more
Big variation, even if short circuit current is than its maximum operating currenbt at the most 10%, in general case under conditions of most harsh
Under, short circuit current is but not so good as that maximum operating currenbt is big, and the present invention removes fuse in the prior art, can guarantee new energy
In the case that source air-conditioning works normally, production cost is saved.
Preferably, as shown in Figure 1, the photovoltaic cell component 10 in the embodiment of the present invention is two, each photovoltaic cell group
An anti-backflow diode 31 is provided on the positive line of part 10.Lightning protection device 32 has two conducting wires, wherein a conducting wire
It is connect with the cathode line of one of photovoltaic cell component 10, the anode of another conducting wire and another photovoltaic cell component 10
Line connection.
Further, air conditioner 20 further includes the first D.C. contactor 21.First D.C. contactor 21 is placed in air conditioner shell
In vivo.Photovoltaic lightningproof confluence component 30 is connect with air conditioner unit, and the first D.C. contactor 21 is arranged in photovoltaic lightningproof confluence group
Between part 30 and air conditioner unit.DC-DC converter is provided between first contactor 21 and air conditioner unit.
The first D.C. contactor 21 in the embodiment of the present invention is original component in the electrical appliance kit of air conditioner 20, passes through
One D.C. contactor 21 can be as the device that cut-offs of the photovoltaic side of photovoltaic cell component 10, therefore the embodiment of the present invention is relative to existing
There is technology that can omit the miniature circuit breaker in photovoltaic lightningproof header box.
It is further preferred that new energy air-conditioning further includes supplementary energy component 40, supplementary energy component 40 and photovoltaic cell
Component 10 is arranged in parallel, and supplementary energy component 40 is connect with air conditioner unit.The supplementary energy component 40 is arranged in air conditioner shell
In vitro, new energy air-conditioning further includes the second D.C. contactor 22 being arranged in air-conditioner shell, and the second D.C. contactor 22 is set
It sets on the positive line of supplementary energy component 40, and between supplementary energy component 40 and air conditioner unit.Second direct current
DC-DC converter is provided between contactor 22 and supplementary energy component 40.
Wherein, the supplementary energy component 40 in the embodiment of the present invention be energy-storage battery, wind energy component, tide energy component,
One or more in thermal energy component or flywheel energy storage component.
