Carrier’s 16JB single effect hermetic

absorption liquid chiller offers a vi-

able alternative to traditional electric

driven chillers. By utilizing low

pressure steam or hot water, the

16JB avoids high cost electricity and

qualiﬁes for utility rebates and in-

centives as a

gas cooling

product.

The utilization of low pressure steam

or hot water in the generator pro-

vides the 16JB with application

ﬂexibility.

• no CFCs; environmentally friendly

• one-stage design for simple, re-

liable operation

• operates using low pressure steam

or hot water

• quiet, vibration-free operation

• few moving parts equates to high

reliability

• Direct Digital Controls (DDC) for

optimum chiller performance.

Features/Beneﬁts

Single effect absorption

provides efficient, economi-

cal water chilling with

minimal use of electricity.

Cost-effective cooling

Alternative-energy chiller — The

16JB offers an alternative for building

owners who want to avoid the high

operating costs associated with electric-

driven chillers. Powered by low pres-

sure steam or hot water, the Carrier

16JB single effect absorption cooling cycle — The 16JB single effect absorption chiller consists of an evaporator, absorber, condenser, steam or hot water generator, solution heat exchanger, refrigerant/solution pumps, purge, controls, and auxiliaries. Water is used as the refrigerant in vessels maintained under low absolute pressure (vacuum). The chiller operates on the principle that under vacuum, water boils at a low temperature (in this case approximately 40 F [4.

Control sequence To start: Local start-up (manual start-up) is initiated by pressing the LOCAL menu softkey which is indicated on the default local interface device (LID) screen. All pre-start safeties are checked to verify that all pre-start alerts and safeties are within limits. If one is not, an indication of the fault will be displayed and the start is aborted. The signal is sent to start the chilled water pump. Five seconds later, the condenser water pump is energized.
