Who makes absorption chillers?

Johnson Controls
Absorption cooling and heating technology acquired by Johnson Controls has served the global market since the 1960s. Having been at the forefront of progress and development in chiller technology for decades, some notable technology milestones include: Parallel flow cycle, double-effect steam chiller (1972)

How much does an absorption chiller cost?

Absorption chillers cost between $500 and $750 per ton. Engine-driven chillers cost up to $1,000 per ton. Electric equipment costs between $300 and $500 per ton.

How does an absorption chiller work?

In short, the absorption chiller chills water via sudden change of pressure. When the water heats up in the generator, the air pressure is high. Water releases the heat and becomes vapor. Then, as it goes through the cooling tower, the vapor cools down in a low-pressure environment and becomes water again.

How is COP of absorption chiller calculated?

Compared to mechanical chillers, absorption chillers have a low coefficient of performance (COP = chiller load/heat input).

Where are absorption chillers used?

Absorption chillers are therefore used mostly for large installations when electricity is limited and/or heat is abundant. Absorption chillers can be used for both heating and cooling purposes simultaneously, by using the process cooling water from the absorber and the condenser.

What is double effect absorption chiller?

Double-effect absorption chillers have two generator/concentrators and the vaporized refrigerant from the high temperature generator/concentrator is the thermal source for the low temperature generator/concentrator, reducing the cooling requirement for the vaporized refrigerant.

Are absorption chillers efficient?

Absorption chillers are being used around the globe as an efficient solution wherever waste heat recovery or a low-cost thermal driving heat source are available, especially as part of a natural-gas or a combined heat and power (CHP) system.

How many types of absorption chillers are there?

three types
There are three types of absorption chillers, each with slight difference from the others: Single-Effect Chiller: regular absorption refrigeration cycle; low-pressure steam (15 psig) or medium-temperature liquids (270°F); COP 0.6 to 0.8 (5.86 to 4.40 kW/ton)

What is direct-fired absorption chiller?

Direct-fired absorption chillers can be used as a primary component for hybrid plants or other applications where electrical demand and consumption are expensive or in short supply. All sizes can act as a chiller and/or heater to supply cold or hot water to condition the building during the summer or winter.

How do I find a real COP?

Coefficient of Performance Formula You can calculate the coefficient of performance by dividing how much energy a system produces by the amount of energy you input into the system.

What is a gas fired absorption chiller?

The chiller uses natural gas or other fuels to fire the absorption refrigeration cycle. Direct-fired absorption chillers can be used as a primary component for hybrid plants or other applications where electrical demand and consumption are expensive or in short supply.

What is steam absorption chiller?

Absorption chillers are used to generate cold water (44F) that is circulated to air handlers in the distribution system for air conditioning. Indirect-fired absorption chillers use steam, hot water or hot gases steam from a boiler, turbine or engine generator, or fuel. cell as their primary power input.

What is an absorption cooling system?

An adsorption or absorption chiller is a cooling system that uses heat instead of electricity to cool something. There are many industrial uses for absorption chillers, including manufacturing plant cooling and wasted heat utilization.
