g) The temperature correction coefficient for solid wood floors has been added (see 5.4.2);

h) Increased the annual output correction coefficient of solid wood flooring (see 5.4.1);

i) The calculation of basic energy consumption per unit output of solid wood flooring production has been deleted (see 5.3);

j) The calculation of the comparable comprehensive energy consumption per unit output of solid wood flooring has been added (see 5.3);

k) Deleted the length correction factor (see 5.4.2 of the 2007 edition);

l) The width correction factor is deleted (see 5.4.3 of the 2007 edition);

m) The thickness correction factor is deleted (see 5.4.4 of the 2007 edition);

n) Deleted the correction coefficient of the degree of mechanization based on the proportion of energy consumption in the processing of the plain board (see 5.4.5 of the 2007 edition);

o) Deleted the monthly heating energy consumption correction coefficient in areas where heating facilities are installed in accordance with national regulations (see 5.4.6 in the 2007 edition);

p) Deleted areas where cooling devices are installed in accordance with national regulations, and the monthly cooling energy consumption correction coefficient (see 5.4.7 of the 2007 edition);

q) The heating energy consumption measurement has been deleted (see 6.3.7 of the 2007 edition);

r) The cooling energy consumption metering has been deleted (see 6.3.8 of the 2007 edition).

This document was proposed by the Forestry Energy Management Sub-Technical Committee of the National Energy Fundamental and Management Standardization Technical Committee (SAC/TC20/SC7) Go out and go out.

1 Scope

This document defines the terms and definitions of the comprehensive energy consumption in the production of solid wood flooring, and specifies the grading index and calculation of the comprehensive energy consumption per unit output.

Principles and methods, energy consumption testing and measurement.

This document is applicable to the calculation and index assessment of the comprehensive energy consumption for the production of solid wood flooring production enterprises. Comparable comprehensive energy consumption for the production of underfloor heating can be referred to According to the implementation (reference use).

3 Terms and definitions

The following terms and definitions apply to this document.

Solid wood floor

Floors directly processed from a single piece of wood that has not been spliced or pasted (see 3.1 in GB/T 15036.1).

Unlacquered solid wood floor Unpainted solid wood flooring (see 3.5 in GB/T 15036.1).

Specific yield comprehensive energy consumption of solid solid wood flooring wood floor production the ratio of the total comprehensive energy consumption of solid wood flooring production to the output of qualified solid wood flooring during the same statistical period.

Comprehensive energy consumption of solid wood floor production During the statistical period, the actual amount of energy consumed by the production enterprise in the production of solid wood flooring shall be converted separately according to the prescribed calculation method it is the sum of standard coal.

Comparable comprehensive energy consumption for unit production of solid wood flooring output of solid wood floor when the solid wood floor is produced, the ratio of the material density above 0.6 g/cm3 is 75 >M>=50, and the annual production of solid wood floor is 100<=M <150 the amount of energy consumed to produce 1 m2 of qualified solid wood flooring when the monthly average temperature is 20°C<=T<35°C.

4 Comparable comprehensive energy consumption classification index per unit output of solid wood flooring the grading index of comparable comprehensive energy consumption per unit output of solid wood flooring should meet the requirements of Table 1;

Note. The production of underfloor heating can increase the comprehensive energy consumption by 70% compared with the latter process
