Hi,
I am interested to find out the equation to work out how much it costs to run electrical equipment.
The particular unit i'm interested in is a mitsi 15 kw cassette.
I want to assess the cost of a both a 3 phase and single phase system when the system is running, also i'd like to to know the generally assumed average running time per hour for a properly sized A/C motor.
Shall we take the supplies as 415v and 230v respectively use the standard powerfactor and the unit price per kwh as £0.10
A woman told me today that the unit in question cost there organisation £60,000 a year to run and i'd love to stick a properly worked equation under her nose or up it. :D
Regards Steve
