I. Chiller Popular Science: Core Principles and Key Components

1. Core Refrigeration Principles

• Compression Process: The compressor sucks in low-temperature and low-pressure refrigerant vapor, which is compressed into high-temperature and high-pressure gas.
• Condensation Process: The high-temperature and high-pressure gas enters the condenser, transfers heat to the cooling medium (air or water), and condenses into high-temperature and high-pressure liquid.
• Throttling Process: The high-temperature and high-pressure liquid is depressurized and cooled through a throttling device (such as an expansion valve) to form a low-temperature and low-pressure gas-liquid mixture.
• Evaporation Process: The gas-liquid mixture enters the evaporator, absorbs heat from the cooled medium (chilled water) and evaporates into gas. The chilled water, with reduced temperature, is then delivered to the equipment or space requiring cooling, completing the refrigeration cycle.

3. Installation and Daily Maintenance

(1) Installation Notes

• The installation site should be well-ventilated, away from heat sources, and reserve maintenance space (≥ 1.5 meters).
• For water-cooled chillers, ensure the cooling tower is installed stably, and the water pipeline connection is sealed without leakage; for air-cooled types, ensure the air inlet is unobstructed.
• The power supply voltage should match the equipment, install leakage protection devices, and ensure reliable grounding.
• Kaidi provides professional installation and commissioning services, operated on-site by experienced engineers to ensure standardized installation.

(2) Daily Maintenance Key Points

• Daily: Check whether the operating pressure and temperature are normal, and whether there is abnormal noise or leakage.
• Monthly: Clean dust on the surface of condensers and evaporators, and check oil level and oil quality.
• Every 6 Months: Replace lubricating oil and drying filters, and clean pipeline filters.
• Annual: Calibrate safety valves and conduct comprehensive inspection of compressors; Kaidi's after-sales team provides annual maintenance services.

IV. Frequently Asked Questions (FAQ)

1. Q: How to choose between air-cooled and water-cooled chillers?

   A: For scenarios with sufficient water sources, pursuit of high refrigeration efficiency and available installation space, water-cooled chillers are preferred; for occasions with inconvenient water sources, limited installation space or small cooling capacity demand, air-cooled chillers are optional. Kaidi can provide customized suggestions according to actual scenarios.
2. Q: What is the service life of Kaidi chillers?

   A: Under standard installation and regular maintenance, the service life of core components is 10-15 years, and the whole unit can operate stably for 8-12 years, far exceeding the industry average level.
3. Q: Why do laser cutting chillers require high-precision temperature control?

   A: Laser equipment is sensitive to temperature during operation; temperature fluctuations will affect the stability of laser output and processing accuracy. Kaidi's laser cutting chillers, with temperature control accuracy of ± 0.1℃, can ensure processing quality.
