What is absorption chiller COP?

The efficiency of an absorption chiller is measured by the coef- ficient of performance (COP), which is defined as useful thermal energy output (i.e., chiller load) divided by heat input. COP is a unit-less number and does not include energy consumed by pumps, fans, or other ancillary components.

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 does a 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, a pipe leads the vapor to the evaporator, where the air pressure is low.

What is cop in Chiller?

Calculating the efficiency of a chiller is fairly simple. It is measured in “COP” which stands for Coefficient Of Performance. The Coefficient of performance is just a ratio of the refrigeration effect produced by the chiller against the amount of electrical energy that went into the machine to produce this.

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 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.

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.
