Variable speed water circulation system is one of the methods that are used for energy optimization for chiller plants.
Alessandro Beghi reported that significant energy savings can be achieved by optimizing chiller operation. In HVAC plants of medium-high cooling capacity, multiple chiller configurations is more frequently adopted than single chiller. The results of study on 3 hospital in Australia show that the energy consumption by Heating and cooling together constitute 44–47%, for hospital buildings. Air-conditioning, boilers, and lighting systems are the main directions for energy efficiency in hospital buildings. HVAC system accounts for 51.36% total energy consumed by most of hospital buildings. Hospitals have a high energy consumption rate.

The results indicate that the sequence of the chiller function and the way in which they are placed in the circuit during a partial load, is in highest importance in view point of energy saving also by Applying of variable water flow system for optimized chiller loading the more energy saving is achieved for hybrid absorption and vapor compression chiller plant. In order to properly understand the pattern of energy consumption, an existing mechanical room in a hospital in Tehran has been studied for five months, and its energy consumption has been compared with the optimized model. This paper examines the behavior and pattern of energy consumption in a hybrid chiller plant that includes a combination of two air-cooled screw vapor compression and three single effect absorption chillers. Cooling load sharing strategies and apply the variable water flow system in chiller plant have a significant impact on energy consumption and consequently with more productivity and environmentally protected. The highly variable cooling demand of the buildings connected to a hybrid chiller plant included absorption and vapor compression chillers to achieve higher energy efficiencies is one of the important issues. * e-mail: plants are the most energy consuming system during summer season in residential, commercial and hospital buildings.
