How to caculate heat gain for a lift ?

[HuyLee]

Hello everyone
Today i want to discuss about a problem that is how to caculate heat gain of a lift. I am making a BEM for saving energy. I should determine each part of the elevator (motor, control, light ... ) to caculate heat gain or We may have any solution for this. Can i have your advices, thanks you

Do you mean the energy expended by the lift motor or pump or the heat gain of the lift compartment itself?

I mean the heat gain of the elevator that impact to the cooling load

What data does manufacturer provide? Sometimes they provide a cooling load number that takes into account typical operation or the average of a ride.

Your cooling load basically is a function of electricity used at operation (up or down) and how often it is expected to operate, and what standby consumption is.

Elevator load effect on one floor of building - HVAC/R engineering

As the title of my post suggests, I am looking into whether or not I should be considering any kind of load (and maybe even pressurization) effect that an elevator will have on one floor of a three story building. The elevator has a separate machine room powering the movement of the elevator...

Whatever energy is supplied to the lift will ultimately be converted to heat load.

You may monitor the currents for individual equipment (possibly with temporary ammeters where required) and arrive at average currents with time. With this you can estimate the average heat loads.

Most of the heat will be the motor. Is that inside or outside of your building load?

Also usage has a huge impact as a stationary lift does no work or output heat

possibly with temporary ammeters

It should be kW meters to take care of pf.
