What is an absorption chiller used for?
Unlike conventional chillers, absorption chillers use the collection of waste heat from other processes or equipment to drive a thermodynamic process that allows water to be chilled and distributed for HVAC needs.
What is absorption chiller system?
For beginners, an absorption chiller is a closed loop cycle that uses waste heat to provide cooling or refrigeration. This absorption cooling cycle relies on three basic principles: When a liquid is heated it boils (vaporizes) and when a gas is cooled it condenses.
How does an absorption chiller work?
Simply put, the absorption chiller does not compress refrigerant vapor; instead, it dissolves the vapor in an absorbent, and transfers the resulting product to higher-pressure environment using a pump with a very low electricity consumption.
How is COP of absorption chiller calculated?
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.
Are absorption chillers efficient?
Absorption chiller technology has evolved dramatically in recent years. 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.
What material is used in an absorption type chiller?
The absorbent is the material that is used to maintain the concentration difference in the machine. Most commercial absorption chillers use lithium bromide. Lithium bromide has a very high affinity for water, is relatively inexpensive and non-toxic.
What are types of chillers?

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)
What is COP for 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 double-effect absorption chiller?
Absorption Chiller Description 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.
What is crystallization in absorption chiller?
Crystallization is most likely to occur when the machine is stopped due to power outage while operating at full load, when highly concentrated solution is present in the solution heat exchanger. 6. Chilled water supply temperature is set too low when the weather and/or exhaust are too hot.
How many Yazaki space chillers are there in the world?
With over 100,000 units operating worldwide, Yazaki is a leading supplier of non-CFC based space cooling. We are proud to announce the arrival of our newest chiller, the WFC-M100. This water-fired chiller produces 100RT of cooling capacity when fed with 194°F hot water at rated conditions.
What is the cooling capacity of a water fired chiller?
This water-fired chiller produces 100RT of cooling capacity when fed with 194째F hot water at rated conditions. It is ideal for larger waste heat applications, whether driven by a solar, microturbine, cogeneration, fuel cell, or other heat source.
What can Yazaki chiller heater be used for?
A Yazaki absorption chiller-heater, using water as the refrigerant, is today’s best choice in air conditioning for protecting the environment and reducing the cost of energy. Capacities of 5 through 200 RT are available to either cool or heat installations such as schools, offices, hospitals, industrial facilities, and hotels.
