The two ends, bottom of described two-way heating power expansion valve are connected with indoor heat converter and outdoor heat converter respectively, and the difference with the prior art part is:
Be communicated with a muffler in two-way heating power expansion valve one side, the caliber of muffler is greater than pipeline size that its two ends connected.
As in such scheme, be arranged on the muffler of two-way heating power expansion valve one side, both can be installed between two-way heating power expansion valve and the indoor heat converter, also can be installed between two-way heating power expansion valve and the outdoor heat converter.
During the two-way heating power expansion valve throttling, high pressure liquid refrigerant can reduce flow velocity in muffler, thereby reaches the purpose that reduces noise.
Usually under heating mode, the noise that cold-producing medium produced of an indoor side is more obvious, thereby correspondingly takes following improvement project:
Between two-way heating power expansion valve and indoor heat converter, be communicated with a stop valve, between two-way heating power expansion valve and stop valve, be communicated with a muffler.
For improving being connected and sealing property of muffler and two lateral lines, the pipeline of muffler both sides is inserted in the hush pipe respectively.And at the mouth of pipe place of muffler, muffler carries out spot welding with two lateral lines and is connected.
For further improving the noise reduction process effect under the heating mode, the pipeline of connection stop valve one side is inserted into the distance in the muffler, and the distance that is inserted in the muffler than the pipeline that connects two-way heating power expansion valve one side is long.
As mentioned above, the cold-warm type transducer air conditioning that the utlity model has silencing means has the following advantages:
1, carries out the noise reduction processing as two-way heating power expansion valve one side of restricting element, reducing the running noises of an indoor side effectively, improving the comfortableness that the room is installed.
2, the syndeton of muffler is optimized, muffler is more fastening with being connected of two lateral lines, sealing property is also better.
