Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for Standardization Work Part 1: Structure and Drafting Rules for Standardization Documents" drafting.

This document replaces GB/T 16732-1997 "Measurement Units and Symbols for Building Heating, Ventilation, Air Conditioning and Purification Equipment". Compared with GB/T 16732-1997, except for structural adjustment and editorial changes, the main technical changes are as follows:

a) Added electric radiators, radiant heating, heat exchangers, electric heating boilers, hot water heat storage devices, phase change heat storage, solar collectors, etc.

Common measurement units and symbols of heating equipment (see 4.1-11~4.1-19, 4.1-22, 4.1-25, 4.1-26, 4.1-32~4.1-41);

b) Deleted the measurement units and symbols of "gravitational acceleration" commonly used in ventilation equipment (see 4.2-3 of the 1997 edition);

c) Added measurement units and symbols for commonly used quantities of ventilation equipment such as "noise of ventilation equipment", "air age", "power consumption per unit air volume" (See 4.2-23, 4.2-26, 4.2-27);

d) Added common units of measurement and symbols for ventilation equipment such as fume hoods (see 4.2-24, 4.2-25);

e) "External static pressure of air-conditioning unit", "power consumption and cooling (heat) ratio", "muffler noise reduction" and "air conditioner (device) reliability life" are added The measurement unit and symbols of common quantities of air-conditioning equipment such as "conventional measurement quantity of cold and heat source equipment of air-conditioning system" (see 4.3-11, 4.3-52~ 4.3-55);

f) The measurement units and symbols of common quantities of air-conditioning equipment such as "air-conditioning equipment medium pressure" and "air-conditioning equipment medium temperature" have been changed (see 4.3-14, 4.3-19, 4.3-13, 4.3-19 of the 1997 edition);

g) Deleted the unit of measurement and symbols of commonly used quantities of air-conditioning equipment in the "air-handling enthalpy difference of air-conditioning equipment" (see 4.3-17 of the 1997 edition);

h) Added cold storage air conditioning system, ground source heat pump system, multifunctional heat pump unit, air conditioning equipment refrigerant, dehumidification, unitary air conditioner, Direct-fired lithium bromide absorption chiller (warm) water unit, steam and hot water lithium bromide absorption chiller, multi-connected air conditioner (heat pump)

Units, water evaporative cooling units, heat pump heat recovery type solution humidity control fresh air units, heat recovery devices, distributed cooling, heating and power energy systems Commonly used units of measurement and symbols for air-conditioning equipment (see 4.3-56~4.3-68);

i) Changed the measurement units and symbols of the commonly used quantities of "efficiency" purification equipment (see 4.4-16, 4.4-18 of the 1997 edition);

j) Increased the usual amount of pollutants such as gaseous pollutants, microorganisms, and viruses, as well as the amount of ultraviolet leakage of purification by-products, and the increase in ozone concentration.

Measurement units and symbols of commonly used quantities of purification equipment such as the addition of volume and designed purification equipment energy efficiency and lifespan (see 4.4-16.9~ 4.4-16.12, 4.4-17.3, 4.4-17.4, 4.4-19.2, 4.4-19.9~4.4-19.14, 4.4-20).
