Absorption System
US Patent:
7891202, Feb 22, 2011
Filed:
Oct 7, 2009
Appl. No.:
12/575177
Inventors:
Brian T. Gallus - York PA, US
Assignee:
Johnson Controls Technology Company - Holland MI
International Classification:
F25B 1/00
US Classification:
62115, 62476
Abstract:
An absorption system includes a generator, a condenser, an evaporator, and an absorber configured to circulate a solution of an absorber and a refrigerant. A purge system removes a non-condensable gas from the absorber. The purge system includes a first pump to remove the solution from the absorber, a connection to remove the refrigerant vapor and the non-condensable gas from a low pressure region of the absorption system, an eductor to receive and mix the solution, a separator to receive the solution and remove the non-condensable gas from it, a tank to receive the non-condensable gas from the separator, a controller to monitor a pressure level of the tank, and a second pump to remove the non-condensable gas from the tank in response to the monitored pressure level in the tank being greater than a predetermined pressure level.

US Patent:
2009002, Jan 22, 2009
Filed:
Jul 17, 2008
Appl. No.:
12/175123
Inventors:
Curtis Christian CRANE - York PA, US

Brian T. GALLUS - York PA, US
International Classification:
G05D 23/00, G05D 3/00, F25B 1/00
US Classification:
700300, 700302, 62498
Abstract:
A pull-down control process for a chiller system is provided. The pull-down control process can override the capacity control process for the chiller system to pull-down the leaving chilled liquid temperature faster than the capacity control process. The pull-down control process can maintain pre-rotation vanes in a fully open position to pull-down the leaving chilled liquid temperature as quickly as possible to a predetermined setpoint.
