Abstract
The invention discloses an air-conditioning outdoor machine, which comprises a shell, a chassis, a compressor, a condenser, a fan motor, an outdoor fan, a baffle plate, a top cap, a low-temperature refrigerant pipe and a high-temperature refrigerant pipe, wherein the low-temperature refrigerant pipe is connected with the compressor and enables low-temperature refrigerants flowing out of an indoor evaporator to flow into the compressor, and the high-temperature refrigerant pipe is connected with the compressor and enables refrigerants compressed by the compressor to be changed into a high-temperature and high-pressure state to flow into an outdoor condenser. The low-temperature refrigerant pipe entering the outdoor machine is firstly wound on the shell of the outdoor fan motor and then connected with the compressor, so that the low-temperature refrigerants flowing out of the evaporator flow through the shell of the outdoor fan motor for carrying out heat exchange and then flow into the compressor. The invention enables low-temperature pipe refrigerants to flow through the surface of the motor for carrying out heat exchange with the high-temperature motor before the low-temperature pipe refrigerants enter the compressor, thereby reducing the surface temperature of the motor, simultaneously improving the refrigerant temperature at the inlet of the compressor, prolonging the service life of the motor and the compressor, and simultaneously avoiding the occurrence of the shutdown phenomenon effectively.
Description
Technical field
The present invention relates to a kind of air-conditioning, particularly relate to a kind of air-conditioner outdoor unit.
Background technology
Usually, air-conditioning is a kind of device that makes its inner refrigerant carry out the kind of refrigeration cycle be made up of compression process, condensation process, expansion process and evaporation process.In air-conditioning, the refrigerant that becomes high-temperature high-pressure state through overcompression can dispel the heat to the outside in condenser, and when flowing through expansion valve, significantly reducing its temperature and pressure, this low temperature, low pressure refrigerant can absorb heat when flowing through evaporimeter then, flow back to compressor at last again.Wherein, compression process, condensation process and expansion process are to carry out in the off-premises station of air-conditioning, and evaporation process then is to carry out under the effect of blowing fan in indoor set and evaporimeter.Fig. 1 is the air-conditioner outdoor unit external structure stereogram of prior art.The prior art air-conditioner outdoor unit structural perspective of Fig. 2 for front panel is not installed.As Fig. 1～shown in Figure 2, the air-conditioner outdoor unit of this prior art mainly comprises: constitute four sides of off-premises station, front end face is provided with air discharge grille 1, and rear end face is provided with a plurality of air inlets, and is formed with the housing 4 of inwardly recessed flange on the upper end-face edge; The chassis 5 that is arranged on the bottom of housing 4 and each parts of off-premises station can be installed on it; At least one is arranged on top one side on chassis 5, the low-temp low-pressure gaseous coolant can be compressed into the compressor 6 of HTHP gaseous coolant; The not shown rear part edge place that is arranged on chassis 5, the condenser that can make refrigerant mobile in it and its surrounding air carry out heat exchange; Be arranged on the top in 5 opposite side centres, chassis, after connecting power supply, can produce the fan electromotor 16 of rotary power; Link to each other with the output shaft of fan electromotor 16, thereby can rotate under the revolving force effect of fan electromotor, thereby air discharge grille 1 row of the air that extraneous air is drawn into the inside of housing 4 and will carries out heat exchange with condenser from the air inlet on housing 4 rear end faces from housing 4 front end faces is to the outdoor fan 7 of the exterior space; Be vertically set on the baffle plate 8 between compressor 6 and condenser and the outdoor fan 7; And extend and four edges 10 forming are formed by end face 9 with from end face 9 bending downwards, can be installed in the top cover 11 on housing 4 upper flanges.
In addition, on chassis 5, also be formed with rhone 2, off-premises station maintenance valve and most of pipeline 3 be set in the bottom, side of air-conditioner housing 4 side.
As shown in Figure 3, the air-conditioner outdoor unit of prior art, the low temperature refrigerant pipe 13 that is communicated with indoor evaporimeter (not shown) directly is connected on the fluid reservoir of compressor 6, make the low temperature refrigerant that from evaporimeter, flows out flow directly into compressor 6 through heat exchange, the refrigerant that becomes high-temperature high-pressure state through overcompression flows in the condenser 15 by high temperature refrigerant pipe 14, can dispel the heat to the outside in condenser 15.
But; because when in the long-time high-temperature severe environment of air-conditioner outdoor unit, moving; motor 16 surface temperatures can continue a higher temperature; even reach the overprotection operating point and cause shutting down phenomenon and occur because temperature is too high; not only influence user's normal use, also shortened the life-span of motor.On the other hand, when under similar 21/15 ℃ of state, turning round, it is low excessively refrigerant temperature also often to occur in the low temperature refrigerant pipe 13, cause compressor 6 inlet temperatures low, thereby the compression process that causes the big temperature difference of compressor, increase the compression load of compressor, reduced the service efficiency of energy, also shortened the service life of compressor simultaneously.
