Based on this, the test analysis was performed on the lines before and after the replacement of the first stainless steel line in table 1 in this example:
1. analyzing the overall capacity of the air conditioner:
the replacement of condenser pipelines is very critical to the influence of the capacity of the air conditioner, and the calculation formula of the air conditioner capacity in engineering is as follows: q K F (t-t2) wherein, Q-air conditioning capacity; k heat exchange coefficient; f-heat exchange area; t-the surface temperature of the pipeline; t 2-evaporation temperature;
1) according to the above calculation formula, when the pipeline is replaced, the heat exchange coefficient is influenced on the premise of the same configuration, so that the capacity is influenced, and the calculation formula about the heat exchange coefficient is as follows: the heat transfer coefficient K is 1/(1/h1+ R +2/h2, wherein R-total thermal resistance, the heat conduction thermal resistance Rc is L/lambda S, the thickness of the L-material and the heat transfer area of the lambda-material heat conduction coefficient S-material.
At present, the pipeline used by the household air conditioner is basically a copper tube, and the heat conductivity coefficient of the copper tube is larger than that of an SUS304 material. However, the copper tube is thick in wall thickness, the SUS304 heat exchange tube can be a thin-wall tube, and the formula shows that the overall heat conduction resistance Rc of the copper tube is different from that of the SUS304 stainless steel tube, and the heat resistance is the capability of obstructing heat transfer to heat flow, so the smaller the heat resistance is, the better the heat resistance is, the heat resistance is in direct proportion to the thickness.
2) And the convective heat release thermal resistance Rw is that the roughness of the stainless steel pipe is small, the surface of the copper pipe is provided with oxide, the two pipes have the same size, and the convective heat release thermal resistance of the stainless steel pipe is less than the convective heat release thermal resistance of the copper pipe under the condition of the same flowing state.
3) And (3) the condensation heat release thermal resistance Rm is that the roughness of the stainless steel pipe is small, the surface of the copper pipe is provided with oxides, the sizes of the two pipes are the same, and the condensation heat release thermal resistance of the stainless steel pipe is less than that of the copper pipe.
To summarize the above: the total thermal resistance of the stainless steel pipes with the same size is slightly lower than that of the copper pipes, and the total heat exchange coefficient is inversely proportional to the thermal resistance, so that the heat exchange coefficient of the stainless steel pipes is larger than that of the copper pipes, and an air conditioning capacity calculation formula can know that under the condition that the sizes of the stainless steel pipes and the copper pipes are different, the air conditioner of the embodiment only adopts the copper pipes to connect the air conditioner of the components in the refrigeration rate, and the overall capacity of the air conditioner is improved compared with the air conditioner of the prior art.
2. Analysis of anti-vibration intensity
Mechanical property test, namely measuring the mechanical properties of the two pipes on a universal material testing machine for the tensile strength and the yield strength to obtain the parameters of the table 2 and the stress-strain curve table 2-mechanical test experiment results of the graph 3 and the graph 4
As can be seen from fig. 3 and 4 in conjunction with table 2, the yield strength and tensile strength of the SUS304 stainless steel pipe are higher than those of the copper pipe, the service life of the SUS304 stainless steel pipe is inevitably longer than that of the copper pipe, and the vibration resistance and deformation resistance are inevitably enhanced in the same vibration and bounce during the operation or transportation of the air conditioner outdoor unit. SUS304 stainless steel pipe intensity is big, and shape at the beginning of the pipeline design, structure, return bend length, return bend radius etc. can effectually guarantee not take place very big change, in compressor 1 working process or in the transportation, use the utility model discloses the pipeline can effectively improve the vibration fracture risk.
3. Corrosion resistance
Salt spray corrosion test: the SUS304 stainless steel tube and the copper tube are respectively placed in an experimental box under a salt spray condition to be stored for a certain time and then the surface corrosion degree is observed, wherein the copper tube can change color, the surface of the stainless steel tube is good, no rust and corrosion trace exist, and the color is bright, and specifically shown in Table 3:
TABLE 3 Corrosion resistance measurement results
| Sample (I) | General corrosion | Impact erosion |
| SUS304 |
5 | 6 |
| Copper tube | 2 | 2 |
As can be seen from the above table, the SUS304 stainless steel tube has good erosion resistance and corrosion resistance, and has good performance under the conditions of common air moisture and impact and salt spray corrosion, and the copper tube is easy to oxidize and the appearance is easy to blacken.
