Refrigerator compressor double walled safety heating helix - has aluminium powder filled space protecting compressor against overwork

摘要

The double wall safety heating helix is used for refrigerator compresses. This arrangement ensures energy recovery from the refrigerators and freezing systems and warms water used for drinking and other purposes. The refrigerant pipeline is separated before the inlet to the condenser. This pipe is extended and formed into a heating helix and held in a tank for heat releasing to the water. The heating helix consists of double wall copper tube. The space between the two helical pipes is filled with aluminium powder. The latter ensures good conductivity and stability. Ends of the tubes do not require liq. tight joining. This arrangement ensures that excessively high working pressures are not used in the compressor in hot seasons.
