The heat load to the space will equal the steam consumption of the equipment, unless the equipment is hooded and extracted.

As with you, the larger laundry facilities were in 4 and 5 star resorts with large chilled water capacities - which was a plus.

RE: laundary air conditioning
the load dissipated to air which the cooling coil shoul handle = hfg steam x steam mass flow rate is that right
hfg steam =2133.4 kj/kg @ 3 bar
is this right??
RE: laundary air conditioning
"hfg steam =2133.4 kj/kg @ 3 bar" - (gauge) yes. Note that the tables are usually in absolute figures.

If you have large dryers, and you are responsible for exhausting them, allow for lint build up in the extraction ducts. Make sure there are clean out doors installed so the ducts can be checked and cleaned.
I recently did a rip out, and re-install on a bank of 4 large dryers in a laundry room of a hotel and found 15 inches of lint in a 30"x 30" duct for a distance of 30 feet.
It was not supposed to be there because the dryers had pre filters. However the maintenance practices at the hotel left a lot to be desired. I will not say any more than that.
