Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but not as the limit to the present invention
It is fixed.
Fig. 1 to Fig. 3 shows the exhaust structure of most of air conditioners in the prior art.As shown in Figure 1 to Figure 3, normal
Under state, the gaseous coolant of low-temp low-pressure is sucked into compressor, and the gaseous coolant of HTHP is discharged by exhaust outlet of compressor,
Enter air conditioner air exhausting arrangement simultaneously, circulating heat exchange system is then discharged into by exhaust structure.Wherein, blast pipe 8 is in vertical
The shape directly bent, temperature-sensitive bag 9 is installed to the side of the remote compressor housing of blast pipe 8.To prevent compressor from starting and transporting
Excessive discharge temperature during row, most air conditioners (can be all commonly called as placing detection means at exhaust outlet about 10cm
" temperature-sensitive bag ").
Inventor is found through experiments that, during using prior art shown in Fig. 1 to Fig. 3, under steady state conditions, a reactor temperature detection
Device can accurately reflect compressor exhaust temperature, and error is minimum, as shown in table 1.
Table 1
But under unsteady state condition, Fig. 1 is into Fig. 3, and temperature-detecting device can not accurately reflect the exhaust temperature of compressor
Degree, especially under the conditions of air-conditioner system lacks fluorine, as shown in the data of table 2.
Table 2
Inventor the analysis found that the gaseous coolant of HTHP is discharged by exhaust outlet of compressor, and at right angle, 90 ° turn
Recovered vertical straight length by centrifugal forces affect, outside (i.e. the side away from compressor housing 7) more refrigerant of distribution in crook
Afterwards, gaseous coolant is uniformly distributed again.If now system lacks fluorine operation, then in vertical straight length, tube wall resistance is larger, cold
Matchmaker more can be distributed in pipe, and a small amount of refrigerant flows along tube wall.Now, if temperature-detecting device is positioned over vertical straight length
Outside, due to being influenceed by copper tube heat exchange, the temperature that temperature-sensitive bag is detected can be less than compressor actual exhaust air temperature.
Therefore, the embodiment of the present invention provides a kind of compressor exhaust temperature detection structure, including：Blast pipe and temperature detection
Device 1 (such as temperature-sensitive bag), the blast pipe includes the first pipeline section 2, the second pipeline section 3 and the 3rd pipeline section 4 being sequentially connected, its
In, first pipeline section 2 is obliquely set relative to second pipeline section 3 with the first angle of non-zero, the phase of the 3rd pipeline section 4
Obliquely set with the second angle of non-zero for second pipeline section 3, the temperature-detecting device 1 is arranged on the described 3rd pipe
In section 4.
So, the blast pipe in the present invention has two bending segments, therefore, by vertical straight length of the prior art
It is improved to after the second pipeline section 3 of above-mentioned the second angle with non-zero and the 3rd pipeline section 4, is similarly limited by the influence of centrifugal force,
The outside of 3rd pipeline section 4 can be distributed more refrigerant, and now temperature-detecting device 1 can accurately reflect the temperature of compressor air-discharging.
Preferably, in first pipeline section 2, the second pipeline section 3 and the 3rd pipeline section 4 are generally aligned in the same plane.For example, described first

4 and first pipeline section 2 can be located at second pipeline section 3 phase the same side.Certainly, the first pipeline section 2, the second pipeline section 3 and
Three pipeline sections 4 can also be located in different planes, so that a spatially three-dimensional structure bent is formed, so, also with utilization
The influence of centrifugal force, more refrigerant can be distributed by making the outside of the 3rd pipeline section 4, so as to accurately reflect the temperature of compressor air-discharging.
In all embodiments of the invention, the 3rd pipeline section 4 is included towards the first side of first pipeline section 2 and the back of the body
From the second side of first pipeline section 2, for more accurately measurement temperature, the temperature-detecting device 1 is preferably mounted at described
Second side of 3rd pipeline section 4.
In the embodiment shown in Fig. 4 to Fig. 6, the 3rd pipeline section 4 in the present invention is the constant straight length of caliber.However,
In the embodiment shown in Fig. 7 to Fig. 9, the 3rd pipeline section 4 can then include pipeline section A5 and pipeline section B6, for example, in pipeline section A5
Two ends set respectively pipeline section a B6, the pipeline section A5 diameter be less than the pipeline section B6 diameter, so as to constitute a contracting
Gauge structure, and the temperature-detecting device 1 is arranged on the pipeline section A5.
Preferably, the ratio of the diameter of the pipeline section B6 and the pipeline section A5 diameter is A, and 1 ＜ A≤4.Preferably, A
=2.
In the embodiment shown in Fig. 7 to Fig. 9, during using undergauge structure, temperature-detecting device can more accurately reflect compression
Machine delivery temperature.For example, table 3 shows temperature-detecting device detection temperature and actual temperature difference condition, table 4 under limit
Show temperature-detecting device detection temperature and actual temperature difference table under the conditions of scarce fluorine.
