In the box body of electrical box 3, comprise all control assemblies, power supply attaching parts, first power supply introduces electrical box 3 from electrical network, electrical box 3 is interior obtains from this for the required electric drive signal of the indoor set 1 of air-conditioner, off-premises station 2, all electrical connections all complete in this electrical box, the installation of electrical box 3 is to be independently arranged on indoorly, and the attribute of the combustible refrigerant that can use according to air-conditioning products is determined and is arranged on away from indoor set and relative safer position.
The installation site of electrical box 3, is in optimized selection according to the attribute of cold-producing medium that air-conditioner uses, if the relative air of cold-producing medium is heavier, the position of electrical box 3 is concordant with indoor set 1 and keep at least 50cm distance with indoor set 1; Or electrical box 3 is arranged on upper right side or the upper left side of indoor set 1 and keeps at least distance of 50cm with indoor set 1.The cold-producing medium leaking can only sink to assembling, more and more far away with the distance of electrical box 3, thereby more and more safer.
If the relative air of cold-producing medium is lighter, the position of electrical box 3 is concordant with indoor set 1 and keep at least 50cm distance with indoor set 1; Or electrical box 3 is arranged on lower right or the lower left of indoor set 1 and keeps at least distance of 50cm with indoor set 1.The cold-producing medium leaking is due to compared with gently upwards floating gathering of air, more and more far away with the distance of electrical box 3, thereby more and more safer.
As a kind of embodiment, as shown in Figures 2 and 3, the quantity of electrical box 3 is two, be respectively indoor set electrical box 31 and off-premises station electrical box 32, the electric controling part of indoor set 1 is arranged in the box body of indoor set electrical box 31, the electric controling part of off-premises station 2 is arranged in the box body of off-premises station electrical box 32, between indoor set 1 and indoor set electrical box 31, can adopt interior dynamo-electric drive signal line to be connected, between off-premises station 2 and off-premises station electrical box 32, can adopt outer dynamo-electric drive signal line to be connected, between indoor set electrical box 31 and off-premises station electrical box 32, be connected by power supply interconnection line and communication signal line.Indoor set electrical box 31 or off-premises station electrical box 32 connect external power, for powering to indoor set 1 and off-premises station 2.In Fig. 2, indoor set electrical box 31 connects external power by power line, and in Fig. 3, off-premises station electrical box 32 connects external power by power line.
The installation site of indoor set electrical box 31 and off-premises station electrical box 32, be in optimized selection according to the attribute of cold-producing medium that air-conditioner uses, in the time that the relative air of cold-producing medium is heavier, the position of indoor set electrical box 31 and off-premises station electrical box 32 is concordant with indoor set 1 and keep at least 50cm distance with indoor set 1; Or indoor set electrical box 31 and off-premises station electrical box 32 are arranged on upper right side or the upper left side of indoor set 1 and keep at least distance of 50cm with indoor set 1.The cold-producing medium leaking can only sink to assembling, more and more far away, more and more safer with the distance of electrical box 3.
In the time that the relative air of cold-producing medium is lighter, the position of indoor set electrical box 31 and off-premises station electrical box 32 is concordant with indoor set 1 and keep at least 50cm distance with described indoor set 1; Or indoor set electrical box 31 and off-premises station electrical box 32 are arranged on lower right or the lower left of indoor set 1 and keep at least distance of 50cm with indoor set 1.The cold-producing medium leaking is due to compared with gently upwards floating gathering of air, more and more far away with the distance of electrical box 3, also just more and more safer.
There are prerequisite three elements in burning: incendiary source, oxidant, incendiary agent reach combustible concentration, and three conditions lack any one, and combustion phenomena just can not occur.For the air-conditioning products that has used combustible refrigerant, possible burning things which may cause a fire disaster is mainly by indoor electrical box (comprising controller in electrical box, relay, connector etc.), outdoor electric component (compressor wiring terminal, capacitor terminal, power supply terminal, controller etc.).In conjunction with the environment for use of air-conditioning products, for burning three elements: oxidant (oxygen), incendiary source (electrical box, outdoor electric component) possess, use the air-conditioner of combustible refrigerant, in running, refrigrant leakage may occur, once leak the lower limit that reaches combustible refrigerant, in the situation that possessing burning things which may cause a fire disaster condition, can burn rapidly catches fire causes fire incident.Therefore: by the electric controling part of combustible refrigerant and air-conditioning self is completely isolated and separated, just can fundamentally avoid the fire hazard that leakage of refrigerant causes to produce.
The air-conditioner of each embodiment above, electrical box is independent of indoor set and off-premises station and independent installation, fundamentally the electric control system of air-conditioner and indoor set, off-premises station that refrigrant leakage may occur are isolated completely, the fire incident that the combustible refrigerant of avoiding dangerous spot burning things which may cause a fire disaster due to electric control system (cut-offfing of Keep Clear-High Voltage circuit, switch) to light leakage causes, facilitate electric checking, the M R of air-conditioning products, and the size of electrical box is no longer subject to the restriction of the physical dimension of indoor set or off-premises station simultaneously.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
