How is polypropylene staple fiber related to refrigerators? Polypropylene staple fiber cannot be directly applied to the refrigerator, but the filler made of polypropylene staple fiber can affect the performance of the refrigerator.

Today, let's talk about the impact of polypropylene staple fiber on the cooling performance when used as a filler.

The operating frequency of the regenerator during the filling of polypropylene staple fiber is also one of the important parameters affecting the performance of the refrigerator. So what is the frequency characteristic? We have studied this. If the frequency is too high, sufficient heat exchange between the working medium in the regenerator and the regenerator packing cannot be achieved, causing the irreversible loss of the regenerator to increase, thereby affecting the overall efficiency . If the operating frequency is too low, a large-sized regenerator needs to be matched with it on the premise of achieving the same cooling capacity.

Under different inflation pressures, the polypropylene regenerator has a better operating frequency. When the inflation pressure is 3.5MPa, 120K performance can be obtained. When the operating frequency is 50Hz, the compressor input power is low, and the corresponding preferred operating frequency is also 50Hz, and the compressor input power is 87.82W and 82W, respectively. In the case of a pressure of 2.8MPa, the frequency characteristics do not change significantly, but the input power at 50Hz is 69.77W. The working frequency of 2.0MPa corresponds to a preferred frequency of 49Hz and 65W input power. The inflation pressure is 1.5. The working frequency corresponding to MPa is 48Hz, and the input power is 55W. In terms of refrigerant performance, frequency is a key issue that directly affects operation, so filled polypropylene staple fibers are essential to pay attention to.
