Chiller technology and energy efficiencyA chiller is largecapacity cooling equipment—180000 Btuh and up—used in commercial and industrial applicationsThe chiller removes heat from a liquid ewater or another refrigerant via a vaporcompression or absorption refrigeration cycleThe liquid can then be circulated through a heat.
Chillers are subject to Canadarsquos Energy Efficiency Regulations which set a performance standard for their energy efficiencyThis helps to eliminate the least efficient products from the Canadian market.
Chillers consume more than 50 of electrical energy during seasonal periods of building useMore than 120000 chillers in the UAre expending more than 30 in additional energy through operational inefficiencies.

FEMP has calculated that a 175ton aircooled chiller meeting the required 107 EER efficiency level saves money if priced no more than 27100 above the lessefficient modelThe best available model saves the average user more it is costeffective up to a price premium of 128200 above the less efficient model.

FEMP’s acquisition guidance and efficiency requirements apply to aircooled chillers that provide space cooling in federal buildingsProduct performance must be measured in accordance with AHRI 550590 test proceduresFreecooling and combination chillerheat pump units are excludedWatercooled electric chillers are covered by FEMP efficiency requirements under a separate product category.
First aircooled chillers from Trane to offer customers the choice of either R134a or R513A a nextgeneration low global warming potential GWP refrigerantThis gives customers the option to choose when to transition to a lower GWP alternative that is convertible and compatible.
HVAC HESS Heating Ventilation amp AirConditioning High Efficiency Systems Strategy 1 Factsheet Chiller Efficiency PEOPLE PRACTICES SYSTEMS The HVAC and common area lighting systems of a 45 year old 5400m 2 commercial office building in Canberra Figure 1 were upgraded in 2010 resulting in a NABERS Energy Rating improvement from 2 to 4.
No matter how efficient your process is there will always be some waste heat producedRemoving this waste heat from the product and process equipment quickly and efficiently is the job of a central chiller system however not all chillers are the sameThe age of the chiller the type of components it uses and the control technology all contribute to the chiller system efficiencyAs production levels rise and fall the chiller system must adjust to meet the actual process load.
Project Description The overall global environment objective of the Chiller Energy Efficiency project in India is to reduce greenhouse gas emissions while simultaneously supporting the phaseout of consumption of Ozone Depleting Substances required under the Montreal ProtocolThe project will accelerate the replacement of centrifugal chillers with efficient nonCFCbased centrihgal chillers in order to promote deployment of energy efficient technologies and products to reduce GHG emissions and support the phaseout of CFC demand in India.
Chiller a machine with or without an integral refrigerant condenser that is designed to use a refrigerant cycle to remove heat from a liquid and to reject the heat to a cooling mediumFor the purposes of the verification mark provision of information and the energy efficiency standard a chiller is not considered to.
The Ascend™ model ACS chiller is the right balance of energy efficiency and quiet operation making it an ideal solution for schoolsAround the world— including over 250000 air and watercooled helical rotary compressors.
The Federal Energy Management Program FEMP provides acquisition guidance for watercooled electric chillers a product category covered by FEMP efficiency requirements.
The function of a process water chiller is to make cold water to cool a mold or other process equipmentAs heat transfers from the process to the water the water warms upThe chiller uses the warm water as a heat source to boil refrigerant in a part of the chiller called the evaporator.
Todayrsquos industrial chillers are designed to cool the refrigerant with water from a cooling tower rather than with ambient airWatercooled chillers are 15 percent more energy efficient than aircooled unitsSince they use smaller condensers and require no fans watercooled units are also smaller and less noisy than aircooled models.
