HVAC & Chilled Water Systems

The challenge

Commercial and industrial HVAC plants move large amounts of heat between chilled water, condenser water and exhaust air. Plant room space is expensive, and part-load efficiency drives operating cost.

How Qingli solves it

• Plate heat exchangers for chilled water exchange, free cooling and loop isolation between clean and dirty circuits.
• Chilled water surface coolers, evaporators and condensers from our second production base cover the cooling side of air handling units.
• Air heat exchangers for fresh air preheating and exhaust heat recovery.

Recommended product types

• Plate Heat Exchanger
• Chilled Water Coil (Surface Cooler)
• Air Heat Exchanger (Steam Coil)

What we need from you

Water flow rates, inlet/outlet temperatures, air volume and entering air conditions, and allowable pressure drop on each side.
