The water-cooled single-unit refrigeration equipment is an efficient and energy-saving refrigeration system that utilizes water circulation to remove heat from the condenser. It is suitable for small and medium-sized commercial or industrial settings. Its core components include a compressor, a water-cooled condenser, an evaporator, and an expansion valve. It achieves heat dissipation through cooling water (such as cooling tower water or chilled water). Compared to air-cooled models, it features high heat dissipation efficiency, low operating noise, and strong environmental adaptability, making it particularly suitable for high-temperature or enclosed spaces. Typical applications include data centers, laboratories, production lines, and other places requiring stable refrigeration. During maintenance, attention should be paid to water quality treatment to prevent scaling and corrosion, ensuring long-term stable performance.
