Problems solved by technology

Since the coils of the motor are all wound with copper wires, and ammonia has a strong corrosion on copper, therefore, the fully enclosed twin-screw refrigeration compressor with the existing structure cannot use ammonia as the refrigerant

Abstract

The invention discloses a fully-closed double-screw typed ammonia refrigerating compressor, which comprises an air inlet pipe, an exhaust pipe, a motor and a double-screw typed compression device; wherein, a magnetic coupling is connected between the motor and the double-screw typed compression device. The coupling comprises a shield sleeve; an opening part of the shield sleeve is fixedly arranged on an opening part of double-screw typed compression device housing, and forms a sealed cavity body with the compression device housing. The compressor can adopt ammonia as a refrigerant so as not to destroy the atmospheric ozone layer and generate greenhouse effect, thereby having excellent environmental protection and energy-saving performance. The compressor can be applied to the refrigeration of air conditioning, vehicles, boats, small refrigeration storage or other fields requiring air compression.

Description

technical field [0001] The invention relates to a refrigeration compressor, in particular to a fully enclosed twin-screw ammonia refrigeration compressor. Background technique [0002] Most of the current refrigeration compressors use Freon as the refrigerant. In order to reduce the greenhouse effect and protect the atmospheric ozone layer, people are trying to replace Freon with low-pollution, environmentally friendly substances. Ammonia is one of the very few working fluids that have no effect on the ozone layer of the atmosphere and have no effect on the global warming effect, and it is cheap and efficient to use as a refrigerant. However, ammonia vapor has a corrosive effect on copper and copper alloys (except phosphor bronze). Therefore, copper and copper alloys cannot be used in ammonia refrigeration systems. In addition, ammonia is highly toxic. Once leaked, it will pollute the air, food, and irritate people's eyes and respiratory organs. Due to the above disadvant...
