Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figure 1, the utility model embodiment provides a kind of new forms of energy air-conditioning, and this new forms of energy air-conditioning comprises: photovoltaic cell component 10, air-conditioner 20 and photovoltaic lightningproof conflux assembly 30.Air-conditioner 20 comprises air-conditioner shell and is placed in the air-conditioner unit in air-conditioner shell, and above-mentioned photovoltaic cell component 10 is connected with air-conditioner unit.The above-mentioned photovoltaic lightningproof assembly 30 that confluxes is arranged in air-conditioner shell, and the photovoltaic lightningproof assembly 30 that confluxes is connected with photovoltaic cell component 10.Photovoltaic lightningproof in the utility model embodiment confluxes in electrical appliance kit that assembly 30 is placed in air-conditioner 20.
Degree of protection to photovoltaic lightningproof header box of the prior art is higher, reaches the requirement of IP65 easily, not only dust-proof, and also has anti-ability of in any direction spraying water, and usually need design, die sinking separately, cost is higher.The assembly 30 that confluxed by photovoltaic lightningproof in the utility model embodiment is arranged in air-conditioner shell, compared to prior art, photovoltaic lightningproof header box of the prior art can be reduced, the additional floor space that photovoltaic lightningproof header box brings can be avoided, cost-saving, simultaneously without the need to considering the installation fixed form of photovoltaic lightningproof header box, reach the object shortening construction period, save engineering later maintenance expense.
Photovoltaic lightningproof in the utility model embodiment assembly 30 that confluxes is made up of counterflow-preventing diode 31 and lightning protection device 32.This counterflow-preventing diode 31 is arranged on the positive pole line of photovoltaic cell component 10, and lightning protection device 32 and photovoltaic cell component 10 are arranged in parallel.Because photovoltaic cell component 10 directly accesses the bus of air-conditioner unit in the utility model embodiment, night photovoltaic cell component 10 do not generate electricity and air-conditioner unit is in holding state time, the bus of air-conditioner unit still has high pressure to exist, if the two ends that this high pressure continues to put on photovoltaic cell component 10 can cause photovoltaic cell component 10 to decay, also can cause the crossfire between not going the same way during the access of multichannel photovoltaic thus accelerate its degree decayed, therefore must increase the generation that this phenomenon avoided by counterflow-preventing diode 31 when photovoltaic accesses.Simultaneously, because photovoltaic cell component 10 is generally installed on roof, the electrical appliance kit very easily surge voltage being introduced air-conditioner 20 by the power line of photovoltaic cell component at thunderstorm weather causes device failure, therefore must by lightning protection device 32 release surge time energy thus the avoid impact of being struck by lightning.
The assembly such as fuse, Mini-type direct current break is provided with in photovoltaic lightningproof header box of the prior art, expensive due to assemblies such as above-mentioned fuse, Mini-type direct current breaks, account for 40% of whole header box cost, cause the cost price of whole photovoltaic lightningproof header box higher.And the utility model embodiment each assembly made full use of in air-conditioner 20 eliminates this kind of expensive device, the initial investment of engineering therefore can be reduced.
Secondly, owing to needing serial connection counterflow-preventing diode in photovoltaic lightningproof header box in prior art, and work is often with thermal losses, therefore need attaches radiator in photovoltaic lightningproof header box, require photovoltaic lightningproof header box to be installed on the comparatively good place of ventilation simultaneously.And counterflow-preventing diode 31 is positioned in air conditioner electrical box by the utility model embodiment, can dispel the heat by the air blast cooling of air-conditioning itself, not only omit radiator but also the integrity problem that improper ventilation brings can be avoided.
Again, the controller in photovoltaic lightningproof header box of the prior art is powered and is usually provided by photovoltaic panel, adds extra stand-by power consumption.And the utility model embodiment indirectly can improve system effectiveness after eliminating photovoltaic lightningproof header box.
Finally, in prior art, photovoltaic lightningproof header box busbar short-circuit fault not only comprises the female short-circuit between conductors of both positive and negative polarity, also comprises the line between branch switch binding post to bus and the short trouble on any point.When there is such accident, fuse of the prior art performs practically no function.Because sunshine the direct current energy sent out different from common AC network, the capacity that AC network has near endless large does backing, powerful short circuit current can be provided, and solar panel can only provide the electric energy of the part solar energy conversion immediately impinged upon above it, without any energy storage, only a part for the solar energy received is converted to electric energy immediately to send, and internal resistance is large again.Therefore, normal condition might as well, short-circuit conditions, short circuit current substantially without great change, even if under the most harsh condition, its maximum operating currenbt of short-circuit current ratio at the most 10%, in usual cases, short circuit current is but large not as maximum operating currenbt, and fuse of the prior art removes by the utility model, when ensureing that new forms of energy air-conditioning normally works, can save production cost.
Preferably, as shown in Figure 1, the photovoltaic cell component 10 in the utility model embodiment is two, the positive pole line of each photovoltaic cell component 10 is provided with a counterflow-preventing diode 31.Lightning protection device 32 has two wires, and wherein a wire is connected with the negative pole line of one of them photovoltaic cell component 10, and another wire is connected with the positive pole line of another photovoltaic cell component 10.
Further, air-conditioner 20 also comprises the first D.C. contactor 21.First D.C. contactor 21 is placed in air-conditioner shell.The photovoltaic lightningproof assembly 30 that confluxes is connected with air-conditioner unit, and the first D.C. contactor 21 is arranged on photovoltaic lightningproof and confluxes between assembly 30 and air-conditioner unit.Dc-dc is provided with between the first contactor 21 and air-conditioner unit.
The first D.C. contactor 21 in the utility model embodiment is the original parts in the electrical appliance kit of air-conditioner 20, can cut-off device as the photovoltaic side of photovoltaic cell component 10 by the first D.C. contactor 21, therefore the utility model embodiment can omit the miniature circuit breaker in photovoltaic lightningproof header box relative to prior art.
Further preferably, new forms of energy air-conditioning also comprises supplementary energy assembly 40, and supplementary energy assembly 40 and photovoltaic cell component 10 are arranged in parallel, and supplementary energy assembly 40 is connected with air-conditioner unit.This supplementary energy assembly 40 is arranged on outside air-conditioner shell, new forms of energy air-conditioning also comprises the second D.C. contactor 22 be arranged in air-conditioner shell, second D.C. contactor 22 is arranged on the positive pole line of supplementary energy assembly 40, and between supplementary energy assembly 40 and air-conditioner unit.Dc-dc is provided with between second D.C. contactor 22 and supplementary energy assembly 40.
Wherein, the supplementary energy assembly 40 in the utility model embodiment is one or more in energy-storage battery, wind energy assembly, tide energy assembly, geothermal energy assembly or flywheel energy storage assembly.
It should be noted that:
1, the utility model embodiment is not only applicable to the new forms of energy air-conditioner set that the type of alternating current input power supplying shown in Fig. 1 is three-phase, and being also applicable to alternating current input power supplying type is single-phase new forms of energy air-conditioner set.
