According to China’s National Standardization Committee, the country’s national energy-saving standard for central air conditioners was approved and will become effective on November 1, 2011.

‘The Technical Specification for Energy-saving Control Device for Central Air-conditioning Chiller System,’ with standard code GB/T 26759 – 2011, was drawn up by an expert committee led by China’s leading central air conditioning company, Guizhou Huitong Huacheng Building Technologies. The standard is China’s first technical standard in the field of central air conditioning control system. The implementation of the standard not only provides a guideline for the control technology of the central air conditioning chiller system, but helps promote the healthy development of the industry. The use of the standard will greatly reduce central air conditioning system energy consumption and bring about social and economic benefits.
