FIELD: refrigerating engineering. SUBSTANCE: device for regeneration of cooling agent has hot gas discharge pipe line 30 connected with liquid distillation temperature regulator 26 which maintains temperature at lowest level to avoid transfer of moisture and to accurately set level of liquid. Distillation chamber contains heat exchange system and distilled cooling agent discharge system 50, as well as inlet pipe line 12 for supply of contaminated cooling agent. Vapor formed above liquid in chamber 16 is discharged into compressor 36 wherefrom hot gases are evacuated through spiral coil 22 immersed in liquid contained in distillation chamber 16. Compressor 36 may feed gases periodically over pipe line past spiral coil 22 in accordance with control signal of temperature regulator 26. In any case, when flow passes either through discharge pipe line or through coil, heat generated by compressor is dissipated by small air-cooled cooler 46. EFFECT: avoidance of air-cooled or water- cooled coolers used for condensation of cooling agent and/or external electric heaters. |
