HYTM Direct Fired Absorption Chiller

• The chiller is equipped with a fully automatic air purging system, 3-stage protection of the chiller vacuum.
• The auto-purge system collects the non-condensable gas inside the chiller to the gas tank automatically by the injector. A pressure sensor monitors the pressure inside the gas tank in real time. When the gas pressure reaches the preset value, the vacuum pump will run automatically to purge the non-condensable gas out of the chiller. No manual operation is required during this whole process.

The chiller is designed with a VFD control system for the LiBr solution pump to adjust the LiBr solution recycling volume during part load operation. This design shortens the chiller startup time and improves the chiller efficiency in part load.

The shell cylinder and water chamber are designed based on stress analysis method, meeting the safety use requirements of the customers in various pressure ranges.

• The solution is dropped and distributed over the tube surface by gravity, eliminating the need for spray pumps and reducing chiller power consumption.
• The solution is distributed in 4 stages to make the entire liquid distribution system more scientific and the liquid film on the heat transfer tube more uniform, improving the absorption and evaporation efficiency.
• The liquid distributor is designed with high-quality stainless steel, never blocked during operation and the chiller life span is much extended.
