About

• Refrigerant: Uses ammonia (

  ), which has zero ozone depletion potential (ODP) and zero global warming potential (GWP).
• Energy efficiency: Offers high energy efficiency, especially at full capacity, with low operational costs.
• Working principle:
  • Evaporation: Ammonia evaporates at low pressure, absorbing heat from the surrounding environment.
  • Compression: A compressor increases the pressure and temperature of the ammonia vapor.
  • Condensation: The hot, high-pressure vapor releases heat to the surroundings in a condenser, turning it back into a liquid.
  • Expansion: The liquid ammonia passes through an expansion valve, which lowers its pressure and temperature, allowing it to return to the evaporator.
• Applications: Widely used for medium to low-temperature applications such as HVAC, cold storage, ice making, pharmaceuticals, and plastics manufacturing.
• Customization: Often customized for specific industrial needs and can operate over a wide temperature range, from positive to negative degrees Celsius.
• Cost-effectiveness: Tends to be cheaper than synthetic refrigerants due to its availability, though prices can fluctuate.
• Compact and adaptable: Modern designs are often skid-mounted and compact, facilitating easier transportation and installation.
