Direct Expansion Air Conditioning<\/strong><\/strong><\/h3>\n\n\n\n

Split Air Conditioning, separating the four major components into two equipment groups, including:
1. Outdoor Unit (Compressor, Condenser)
2. Indoor Unit (Expansion Valve, Evaporator)
Transferring the vibration and noise caused by the compressor to the outdoors, providing a quieter environment.<\/p>\n\n\n\n

Chilled Water System<\/strong><\/strong><\/strong><\/h3>\n\n\n\n

\u203bThe chilled water system has no pipe length restriction, and pumps are configured according to the system size.\n
Structure of Air-Cooled Chilled Water System

Simplified Air-Cooled Chilled Water System Architecture
Chilled Water Process:
1. The chiller produces chilled water at 7\u00b0C.
2. The chilled water is pumped to the site, where it exchanges heat with the indoor air through cooling equipment, supplying cool air to achieve a comfortable indoor environment.
3. After absorbing the indoor heat, the temperature of the chilled water rises from 7\u00b0C to 12\u00b0C.
4. The 12\u00b0C chilled water returns to the chiller, where it is cooled back down to 7\u00b0C.
The heat is then dissipated to the atmosphere through the condenser and fan.<\/p>\n\n\n\n

4. The 12\u00b0C chilled water returns to the chiller, where it is cooled back down to 7\u00b0C.

Cooling Water Process:
1. The cooling water pump sends 32\u00b0C cooling water into the chiller, where it absorbs heat and warms up to 37\u00b0C. It then enters the cooling tower, where the heat is dissipated into the atmosphere, cooling the water back down to 32\u00b0C.
2. The 32\u00b0C cooling water returns to the chiller to absorb heat again and warm up to 37\u00b0C.<\/p>\n\n\n\n
