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

Polypropylene staple fiber requires one of the important parameters of the performance of the refrigerator when it needs to be refilled. Then what is the characteristic of the frequency? We have studied this. The frequency is too high, and there is no sufficient heat exchange between the working medium and the regenerator packing in the regenerator, which causes the irreversible loss of the regenerator to increase, thus affecting the efficiency of the whole machine. . If the operating frequency is too low, a large regenerator is required to match the same cooling capacity.

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