Why can't ammonia compressor be made of copper?

1. Ammonia compressor is the core equipment of ammonia refrigeration system, and the material selection is directly related to the operation safety.

2. Why can't the ammonia compressor be made of copper? This starts with the chemical reaction between ammonia and copper. When ammonia contains moisture, it will react with copper and copper alloys to form copper-ammonia complex. Long-term operation will gradually damage the copper parts of ammonia compressor, which will affect the sealing performance and lead to ammonia leakage, and even lead to equipment failure and even safety accidents. Therefore, in order to ensure the reliable operation of ammonia compressor, copper-containing materials are strictly avoided in its manufacture.
