Unitary air conditioners; Air conditioning machines, comprising a motor-driven fan and elements for changing the temperature and humidity, including those machines in which the humidity cannot be separately regulated. (HS 8415). Energy and heat transfer engineering in general (ICS 27.010)
National Standards of the P.R.C., Minimum Allowable Values of Energy Efficiency and Energy Efficiency Grades for Unitary Air Conditioners (4 page(s), in Chinese)
The standard is mandatory and specifies the minimum allowable values of the energy efficiency, energy efficiency grades and test methods for unitary air conditioners. The standard applies to unitary air conditioners that use motor-driven compressor, with indoor static pressure of 0 pa (gauge pressure) , including unitary air conditioners used in computer and data processing room, unitary air conditioners used in communication base stations, and constant temperature and humidity machines.
