Hereinafter, will describe in detail according to the chassis in a kind of off-premises station of air-conditioning of embodiment.
Fig. 3 is the stereogram that illustrates according to the chassis in a kind of off-premises station of air-conditioning of embodiment.Fig. 4 is the viewgraph of cross-section along the A-A ' line of Fig. 3.Fig. 5 is the viewgraph of cross-section along the B-B ' line of Fig. 3.
Referring to Fig. 3 to Fig. 5, chassis 56 comprises: compression support 561, and compressor 21 is seated on this compression support 561; The compressor fixed part 562 of fixing compressor 21; Motor fixing base 563, motor fixed part 35 are seated on this motor fixing base 563; Heat exchanger seat 567, heat exchanger 25 are seated on this heat exchanger seat 567; And the condensed water osculum 568 that is used to discharge the condensed water that results from heat exchanger 25 places.
56 end face protrudes compression support 561 from the chassis.Compressor fixed part 562 is arranged at compression support 561, and by the ccontaining and connection holes (not shown) that is attached to compressor 21 so that compressor 21 is fixed to chassis 56.
Also 56 end face protrudes motor fixing base 563 from the chassis.Motor fixing base 563 is provided with and is used to be attached to the connection part 564 of motor fixed part 35 and be used to guide motor fixed part 35 to make it put the guidance part 565 that puts in place.Part to the end face on chassis 56 is cut, upwards bending then, thus form connection part 564 and guidance part 565.The width of guidance part 565 narrows down towards its end and is long along fore-and-aft direction.Be limited with connection holes 566 in connection part 564, the connection unit (not shown) that is used for motor fixed part 35 is attached to chassis 56 passes connection holes 566.
Also 56 end face protrudes heat exchanger seat 567 from the chassis.The side end of the end face on chassis 56 and rearward end are provided with a plurality of heat exchanger seats 567.When heat exchanger 25 is seated on the heat exchanger seat 567, the bottom end of heat exchanger seat 567 contact heat exchangers 25.Thereby, can heat exchanger 25 vertically below heater 569 is set.
Condensed water osculum 568 is arranged in the rearward end on chassis 56, that is, be arranged between heat exchanger 25 downsides, the heat exchanger seat 567.End face on the chassis 56 except that protuberance (comprising compression support 561, motor fixing base 563 and heat exchanger seat 567) tilts towards condensed water osculum 568 downwards.That is to say that under the situation fixing by securing supports 70 of chassis 56, condensed water osculum 568 is arranged to be arranged in its lowest position of the end face on chassis 56.In addition, the end face except that protuberance can be used as and is used to make condensation flow to arrive the drainage channel of condensed water osculum 568 on the chassis 56.
In addition, except compression support 561, motor fixing base 563 and heat exchanger seat 567, chassis 56 is provided with a plurality of ribs 560.Rib 560 is gone back the flow direction of direct condensed water when strengthening chassis 56.
By means of chassis 56, can more effectively discharge condensed water.Particularly, when the condensed water that results from heat exchanger 25 or refrigerant pipe 27 places collected on the end face on chassis 56, condensed water was because deadweight flow to condensed water osculum 568 along drainage channel, thereby improved the discharging of condensed water.
Because compressor 21 and heat exchanger 25 be by compression support 561 and heat exchanger seat 567 and spaced apart with the end face on chassis 56, thereby prevent to contact with heat exchanger 25 with compressor 21 at the condensed water that heat exchanger 25 or refrigerant pipe 27 places produce and are pooled in the end face on chassis 56.Therefore, prevented by condensed water cause to the corrosion of compressor 21 and heat exchanger 25 and improved the performance of heat exchanger 25.
In addition, even below outside air temperature is reduced to zero degrees celsius and condensed water when on the surface of heat exchanger 25, freezing, also can melt and remove the condensed water that freezes by the operation of heater 569.Particularly, because heater 569 is arranged on the vertical below of heat exchanger 25, therefore the air by heater 569 heating moves upward naturally, thereby heats whole heat exchanger 25.This makes it possible to improve the efficient of defrost operation.
Although invention has been described with reference to a large amount of illustrated embodiment of the present invention, but should be understood that, those of ordinary skills can expect other many remodeling and embodiment, and these remodeling and embodiment all will fall in the spirit and scope.More specifically, can in the scope of this specification, accompanying drawing and claims, aspect the layout of parts and/or main combination layout, make multiple variation and remodeling.Except that variation aspect parts and/or the layout and remodeling, those of ordinary skills also will understand alternative purposes.
