Absorption chiller capacity control

Conventional absorption mechanism of cold water cooling system USES for to concentrator heat stress adjustment method to control the system implementation capacity. Use of conventional steam for heating system in full load condition, the steam pressure for 12 - commonly About 14 psig, when general capacity, you just need to the pressure of about 6 psig. Steam pressure regulating valve control can be applied. Water and direct heating unit can also adopt the same method to control. Some manufacturers also use other controller to realize the capacity control, can control the fluid flow inside the unit, such as dilute solution flow control to the concentrator is a kind of practical method, because of lower capacity, needs less concentrated solution quantity accordingly.
