2019年8月13日 · The MA Board of Elevator Regulations has removed the longstanding amendment to ASME A17.1: Safety Code for Elevators and Escalators requiring a means of elevator ventilation to the outer air from enclosed elevator hoistways and machine rooms. Previously, 524 CMR amended ASME Section 2.1.4 and required natural or mechanical ventilation for all ...

Recent changes to building codes and introduction of new elevator systems have caused some confusion regarding ventilation of elevator hoistways and machine rooms for control of temperature, humidity and smoke for all types of elevators and for control of …

The increased application of machine room-less elevators has resulted in confusion on how to apply code requirements when there is no machine room. This column discusses mechanical design considerations for elevators, code and ASME implications, and architectural coordination.

Elevator machine rooms, machinery spaces that contain the driving machine, and control rooms or spaces that contain the operation or motion controller for elevator operation shall be provided with an independent ventilation or air-conditioning system to protect against the overheating of the electrical equipment. The system shall be capable of ...

Ventilation rates for Storge Room (0.12 cfm/ft2, 0 cfm/person), Electrical Equipment Rooms (0.06 cfm/ft2, 0 cfm/person) and Elevator Machine Rooms (0.12 cfm/ft2, 0 cfm/person) are are now included in Table 6-1, 62.1-2007, whereas 62.1-2004 did not include these spaces in Table 6-1.

2009年10月19日 · ASME A17.1, “The Safety Code for Elevators and Escalators,” requires machine room temperature to be as determined by the elevator manufacturer. Most building elevator mechanics and manufacturers maintain elevator machine rooms between 60°F and 80°F with 35% to 60% relative humidity. The heating system for the machine room also is a built-in unit.

Having appropriate ventilation for your machine room is required by law with certain local code requirements calling for ventilation fans to have a specific velocity, correct fan motor placement and emergency ventilation protocols. Because these regulations vary by location, the best way to improve your machine room ventilation is by asking ...

2005年7月1日 · Usually machine rooms are ventilated with an automatic damper for makeup air, (from the outside), and an exhaust fan w/damper and thermostat control. However an AC unit may be required depending on the climate & heat load produced by the elevator equipment.

2007年8月1日 · Hydraulic and traction elevators require machine rooms adjacent to the elevator hoistway and therefore take up leasable area in buildings, while requiring additional support services that include dedicated HVAC. The mechanical engineer’s design that relates to the elevator system and ventilation requirements for the machine room and elevator ...

2003年1月24日 · In US (MA) code requires elevator machine rooms to be ventilated (not just conditioned). Provisions allow a ventilation substitute of machine room connection via ductwork without a fan (there are requirements regarding duct pitch) to the associated hoistway.
