If you want to use an absorption chiller as the central core of your building's air conditioning system, stay with us until the end of this article to get the necessary information about the features, technical specifications, how to estimate capacity, choose the right brand, and purchase order tips for absorption chillers.
The absorption chiller is one of the refrigeration production equipment in air conditioning systems of buildings, which have much lower electricity consumption than compression chillers of the same capacity but require a lot of thermal energy (such as hot water - steam - direct flame).
This thermal energy evaporates the water dissolved in lithium bromide to create cooling in the absorption chiller generator. The resulting water vapor enters the condenser, where it is distilled due to contact with the water coils of the cooling tower and enters the evaporator.
Due to the presence of vacuum (0.01 atm pressure) in the evaporator, the evaporated distilled water absorbs its latent heat from the fluid coils of the air conditioning system (usually water). Then, the water vapor resulting from this process is absorbed by lithium bromide in the absorber; this diluted lithium bromide enters the generator by the solution pump. The dry lithium bromide is also returned to the absorber in order to absorb water and be diluted.
The refrigerant pump in absorption chillers is responsible for transferring water from the evaporator to the pipes carrying the fluid of the ventilation system.
These four types of absorption chillers in terms of energy consumption:
The following are the main components of an absorption chiller:
Nominal cooling capacity and actual cooling tonnage of the device (TR)
Type of absorption chiller (spa, steam, hot water, direct flame)
For advice and to get more information about how to choose the absorption chiller you need, you can consult with the experts of DamaTajhiz HVAC Group.
In general, facility experts calculate the absorption chiller capacity required in each project, in addition to calculating parameters such as geographical conditions, altitude above sea level, relative air humidity, type of building use, type of materials used, and implementation of the building facade, the direction of the building relative to They pay attention to the sun's radiation angle, the number of floors and the surface of the building's substructure, the number of people and small and large electrical equipment inside the building, etc., the amount of cold water required and sufficient reliability coefficients in the performance of the absorption chiller.
But if you want to use the possibility of calculating the chiller required by residential and office buildings in climatic conditions like Tehran, you can consider the nominal capacity of 5 tons of refrigeration for every 100 square meters of the building. In absorption chillers, ammonia is the main source of energy supply for cooling city gas.
In lithium bromide absorption chillers (capacity above 30 tons of refrigeration), the main energy source is hot water or steam (except for direct flame absorption chillers, where the burner with suitable fuel is installed directly on it).
