6、RIGERATING EQUIPMENT Section 1. Purpose 1.1 Purpose. The purpose of this standard is to estab- lish, for air-conditioning and refrigerating equipment, preferred symbols to represent the functions of com- monly used electrical and electronic parts in order to facilitate the understanding of electrica

7、l wiring dia- grams. 1.1.1 This standard is intended for the guidance of the industry, including manufacturers, consult- ing engineers, distributors, installers, contractors, servicing personnel and other users. 1.2 Review and Amendment. This standard is subject to review and amendment as the techno

8、logy of the industry advances. Section 2. Scope 2.1 Scope. This standard applies to all electrical and electronic parts of air-conditioning and refrigerating sys- tems including related accessories and controls. Section 3. Definitions 3.1 Graphic Symbols for electrical engineering are a shorthand us

9、ed to show graphically the functioning or interconnections of a circuit. A graphic symbol repre- sents the function of a part in the circuit.* Graphic sym- bols are used on schematic or elementary diagrams, or as applicable on connection or wiring diagrams. Graphic Symbols are correlated with parts

10、lists, descriptions, or instructions by means of designations. A symbol shall be considered as the aggregate of all its parts. 3.1.1 IEC Identification. Symbols that have been recommended by the International Electrotechni- cal Commission are indicated by E 3.1.2 Applications where shown are example

11、s of preferred combinations of symbols. No attempt has been made to list all possible applications. Ad- ditional applications may be devised provided they are a reasonable and intelligible use of other sym- bols (For application of symbols in electrical dia- grams see ANSI Standard Drafting Practice

12、s for Electrical and Electronics Diagrams-Yl4.15- 1966; Y14.15a-1971 and Y14.15b-1973). For example, when a resistor is employed as a fuse, the fuse symbol is used. For reference designation information, see ANSIIIEEE 200- 1975, Reference Designations for Electrical and Electrtiics Parts and Equipme

13、nt. 3.1.2.1 Correlation of Symbol Parts. For sim- plification of a diagram, parts of a symbol for a device, such as a relay or contactor, may be separated. If this is done, provide suitable des- ignations to show proper correlation of the parts. 3.1.2.2 Envelope. An envelope may be used with a symbo

14、l and does not normally indicate evacuation or pressure. However, when used with electron-tube component symbols, the en- velope indicates a vacuum enclosure unless otherwise specified. 3.2 Schematic or Elementary Diagram. A diagram which shows, by means of graphic symbols, the electrical connection

15、s and functions of a specific circuit arrange- ment. The schematic diagram facilitates tracing the cir- cuit and its functions without regard to the actual phys- ical size, shape, or location of the component device or parts. 3.3 Orientation. Except where noted, the orientation of a symbol on a draw

16、ing, including a miiror-image pres- entation, does not alter the meaning of the symbol. Let- ters and numbers that constitute a part of a symbol shall not be presented in mirror-image form. 3.4 Line Width. The width of a line does not affect the meaning of the symbol. In specific cases, a wider line

17、 may be used for emphasis. 3.5 Symbol Size. A symbol may be drawn to any pro- portional size that suits a particular drawing, depending on reduction or enlargement anticipated, If essential for purposes of contrast, some symbols may be drawn rel- atively smaller than the other symbols on a diagram.

18、It is recommended that only two sizes be used.on any one diagram. 3.5.1 Relative Symbol Size. The symbols shown in this edition of the standard are in their correct relative size. This relationship shall be maintained as nearly as possible on any particular drawing, regardless of the size of the sym

19、bol used. 3.5.2 Arrowheads. The arrowhead of a symbol may be closed+or open+unless otherwise noted in this standard. 3,5.3 Angle of Connecting Lines. In general, the angle at which a connecting line is brought to a graphic symbol has no particular significance un- less otherwise noted or shown in th

The standard symbol for a ter- mina

21、l (o) may be added to each point of attachment of connecting lines to any one of the graphic symbols. Such added terminal symbols should not be considered as part of the individual graphic symbol, unless the terminal symbol is included in the symbol shown in the standard. 3.7 Addition of Supplementa

22、ry Data. Details of type, impedance, rating, etc., may be added when required, adjacent to any symbol. If used, abbreviations should be from ANSI Y 1.1 1972(R1984) Standard Abbreviations for Use on Drawings and in Text. Letter combinations used as parts of graphic symbols are not abbreviations. Sect

Contacts, Switches, Contactors, Relays and Solenoids 6.1 Basic Contact Assemblies. The standard method of showing a contact is by a symbol indicating the circ

The actuating de- vice may be of a mechanical, electrical, or other nature, and a clarifying note may be necessary with the symbol to explain the proper point at which the contact func- tions; for exam
