HWAR-L SINGLE EFFECT HOT WATER ABSORPTION CHILLER

Description

HWAR-L - Single Effect Low-temperature Hot Water Driven Absorption Chiller for cogeneration and industrial use.

30~2,000RT (105~7,033kW)
Driving Temperature: 80~120℃

Highest delta T in hot water
Achieved leaving temperature of hot water down to 70℃, by the unique 2-shell structured condenser and generator 

Lowest power consumption and footprint
Reduced absorbent solution flow rate by the unique 2-level structured evaporator and absorber. Less solution flow rate minimized the power consumption of the solution pumps as well as the size of machine. 60% lesser in power consumption, and 20% smaller in dimension compared to the products of other companies.

Highest COP
Achieved COP 0.825, the highest in single effect hot water driven absorption chillers

Application versatility
Designed to suit a variety of applications, from comfort cooling to providing chilled water for process applications, HWAR-L offers versatility for almost any job where hot water is available as the heat source. HWAR-L is sure to be the right choice for either new construction or retrofit applications.

Excellent part load performance
The standard concentration control system allows stable part load operation at cooling water temperatures as low as 17℃ without the need for a cooling water bypass. For maximum efficiency, a variable frequency drive pump (option) automatically maintains optimum solution flow between generator and absorber at all operating condition. This will result in improved part-load efficiency. HWAR-L has a continuous operating range from 100% to 10% of rated machine capacity.

 

*Detailed product explanation

■Refrigerants evaporate from an evaporator and cool cold water flowing inside of evaporator tubes. Refrigerants evaporated at this time go to an absorber and get absorbed into a thick absorption liquid (a concentrated solution) flowing down from a generator.

■Thick solution (a concentrated solution) from a generator and weak solution (a dilute solution) from an absorber exchange heat at an absorption heat exchanger located at the upper part of the absorber to improve absorption power of the concentrated solution and enhance the efficiency of the chiller.

■The concentrated solution coming through the absorption heat exchanger absorbs refrigerant vapor and becomes a weak solution (a dilute solution). Absorption heat generated at this time is conveyed to cooling water.

■Absorption liquid (a dilute solution) diluted at an absorber goes to a generator through an absorption heat exchanger and a heat exchanger. Hot water of 95℃ heats this dilute solution and generates refrigerant steam.

■Solution (a dilute solution) diluted at an absorber goes to a generator through an absorption heat exchanger and a heat exchanger. Hot water of 95℃ heats this dilute solution and generates refrigerant vapor.

■Refrigerant steam generated from the generator gets condensed outside of condenser tubes and flows down to the evaporator. Cooling water absorbs heat generated when refrigerant gas gets condensed at condenser tubes.
