A/c Unit for a space with No drain

[Jsf721]

My son rented an apartment and one of the rooms how no outside wall.

I need to air-condition that space so it can be rented as a bedroom. Landlord put in a narrow window 5" x 30" along the top of 2 walls to let light in but it just opens to the living room.

I cannot see how a drain would be run, is there an AC that does not make condensation?

thanks

You will need outside air too my friend.

And there is no place to vent the hot air from a traditional unit.

You're making this really difficult.

A mini-split could be made to work, perhaps with a condensate pump. It will at least need a plumbing path (3" diameter cross section) to outside.

I thought a bedroom had to have a window to be a bedroom -- egress.

you have a few options provided that the landlord allows it...

1) split AC. if you can pull a dedicated 240v line near that opening.

2) portable AC.... they do have a portable air vent to vent hot air via a flexible duct outside (duct is split, 1/2 for incoming and the 1/2 for exhaust) I htink it is $300-$500-ish

3) If you get an ac that have condensate drains, they do have condensate pump that you can wire inline and send the condensate water out via a 1/4 / 1/2 vinyl tube or something.
4) you landlord is not going to like this one... they do have water cooled AC... instead of a traditional condenser that is air cooled evaporator, they have the one with liquid cooled heat exchange... but very very very pricey (about $3000) and waste lots of water, unless you have a water tower (not included).

I have some experience with liquid cooled air conditioning units. There is no call for it here. They make sense if you have a chiller, or need to air condition in the winter (in a data center for example), but recirculating water for the most part carries heat less efficiently than refrigerant plumbed over the same distance.

Good point.

I am just providing an option that would work... maybe OP would go for it and situation would work... Easiest is to cut a windows, but most likely that bedroom is not an original partition to the apartment.

If you are in NYC, most likely that apartment is illegal. one of the sign to look for is the landlord includes Electricity/Gas and that is not a high rise building / co-op / condo build back in the 70s.

I just got as video, may be able to snake a vent line out into the living room and tap into the accordion material in the living room window unit. Need to find a fitting for that, winder if that make one or I need to fabricate something.

Portable a/c units are OK for spot cooling in a shop or something. In an enclosed space they don't work so well. Think about all of that hot air that is being blown outside. It has to come from somewhere. It comes from sucking hot, outside air through every opening in the structure because it is creating negative pressure inside.

There are a few that have dual air tubes, one for intake and one for exhaust, but the ones I've see have pretty bad reviews.

IF the rest of the apartment has adequate cooling, you could get some of that cool air into that bedroom using a transfer fan like this: https://www.sylvane.com/tjernlund-aireshare-room-to-room-transfer-fan.html

Without a window, it’s a closet, not a bedroom.

I would not rent out a room without an emergency egress window. NY code requires natural light and openings for emergency use of specific minimum dimensions in sleeping rooms. In case of an emergency, your son would be 100% at fault if his tenant is injured or killed.
