28、OUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover nonducted, stationary or xed heat recovery ventilators for household, commercial, or industrial use and intended to be employed in accordance with the National Electrical Code, ANSI/NFPA 70. 1.2 These requirements cover heat re

29、covery ventilators rated 600 volts or less. 1.3 These requirements cover heat recovery ventilators that may be mounted through a wall or ceiling, or in a window. 1.4 These requirements cover heat recovery ventilators that may employ short ducts intended to bring air to and from the equipment. These

30、requirements do not cover heat recovery ventilators employing ducts intended to supply conditioned air for environmental heating and/or cooling or distribute air throughout a building; such units are judged under the requirements in the Standard for Ducted Heat Recovery Ventilators, UL 1812. These r

31、equirements do not preclude a preheater provided as part of the air exchange system. 2 Undated References 2.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 3 Units of Measur

32、ement 3.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 4 Glossary 4.1 For the purpose of this standard the following denitions apply. 4.2 CONTROL, AUTOMATIC A control in which at least one aspect is non-manual. 4.3 CONTROL,

33、AUXILIARY A device or assembly of devices that provides a functional utility, is not relied upon as an operational or protective control, and therefore is not relied upon for safety. For example, an efficiency control not relied upon to reduce the risk of electric shock, re, or injury to persons dur

34、ing normal or abnormal operation of the end product is considered an auxiliary control. 4.4 CONTROL, MANUAL A device that requires direct human interaction to activate or rest the control. 4.5 CONTROL, OPERATING A device or assembly of devices, the operation of which starts or regulates the end prod

35、uct during normal operation. For example, a thermostat, the failure of which a thermal cutout/limiter or another layer of protection would mitigate the potential hazard, is considered an operating control. Operating controls are also referred to as “regulating controls”. FEBRUARY 29, 2012 NONDUCTED

36、HEAT RECOVERY VENTILATORS - UL 1815 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.6 CONTROL, PROTECTIVE A device or assembly of devices, the operation of which is intended to reduce the risk of electric shock, re or injury to persons du

37、ring normal and reasonably anticipated abnormal operation of the appliance. For example, a thermal cutout/limiter, or any other control/circuit relied upon for normal and abnormal conditions, is considered a protective control. Protective controls are also referred to as “limiting controls” and “saf

38、ety controls”. 4.7 CONTROL, TYPE 1 The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain conditions) of its operating value, operating time, or operating sequence has not been declared and tested under this standard. 4.8 CONTROL

39、, TYPE 2 The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain conditions) of its operating value, operating time, or operating sequence have been declared and tested under this standard. 4.9 DUCT FAN A straight-through ventilat

40、or provided with anges for connection to a duct and which may be used with heated air. 4.10 ENCLOSURE That part of a unit which by itself or in conjunction with barriers reduces the risk of contacting all or any parts of the unit that may otherwise present a risk of electric shock or injury to perso

41、ns and/or prevents propagation of ame initiated by electrical disturbances occurring within. 4.11 FIELD WIRING TERMINAL A terminal to which a wire may be connected in the eld, unless the wire and a means of making the connection such as a pressure terminal connector, soldering lug, soldered loop, or

42、 crimped eyelet that is factory assembled to the wire are provided as part of the heat recovery ventilator. 4.12 FUNCTIONAL PART A part other than an enclosure or structural part that is necessary for the intended operation of a unit. 4.13 HEAT RECOVERY VENTILATOR A product intended to remove air fr

43、om a building, replace it with air outside the building and in the process transfer heat from the warmer to the colder air. 4.14 MOTORS: a) Open Motor A motor having ventilating openings that permit passage of external cooling air over and around the windings of the motor. b) Totally Enclosed Motor

44、A motor that is enclosed so as to prevent the free exchange of air between the inside and outside of the case but not sufficiently enclosed to be termed airtight. c) Totally Enclosed Fan-Cooled Motor A totally enclosed motor with external cooling by a fan or fans integral with the motor but external

45、 to the enclosing parts. 4.15 POWER VENTILATOR A ventilator that consists of an impeller which may be of the centrifugal, axial, or propeller type and an integral driver. A power ventilator is: a) Installed in a weather-resisting base intended to t, usually by a curb, over a wall or roof opening, or

46、 b) Provided with anges for connection to a duct. 4.16 STRUCTURAL PART A part used in such a manner that failure of the part may present a risk of electric shock or injury to persons.

47、REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.17 USER SERVICING Any form of servicing, such as routine cleaning, changing a lter or a heat exchange medium, and the like, that might be performed by personnel other than those trained to maintain the appliance. CONSTRUCTION 5 General 5.1 An

48、 appliance shall employ materials that are acceptable for the particular use. 6 Component 6.1 A component of a product covered by this standard shall: a) Comply with the requirements for that component; b) Be used in accordance with its rating(s) established for the intended conditions of use; c) Be

49、 used within its established use limitations or conditions of acceptability; d) Additionally comply with the applicable requirements of this end product standard; and e) Not contain mercury. Exception No. 1: A component of a product covered by this standard is not required to comply with a specic component requirement that: a) Involves a feature or characteristic not required in the application of the component in the product; b) Is superseded by a requirement in this
