Title:
REFRIGERATING APPARATUS USING NON-AZEOTROPIC MIXED REFRIGERANT
Document Type and Number:
WIPO Patent Application WO/2021/034135
Kind Code:
A1
Abstract:
A refrigerating apparatus using a non-azeotropic mixed refrigerant may include a compressor operable in a continuous operation mode and configured to compress the non-azeotropic mixed refrigerant, a condenser configured to condense the refrigerant compressed by the compressor, an expander configured to expand the refrigerant condensed by the condenser, and an evaporator configured to evaporate the refrigerant expanded by the expander. A pressure difference (△P) of the non-azeotropic mixed refrigerant has a value included in a range of 340 kPa <△P < 624.7 kPa. Therefore, reliability of components, such as a piston, in the refrigerating apparatus using the non-azeotropic mixed refrigerant may be further improved.
