Looks like some type of Oncidium to me, Pia-Louise. But I'd like to wait for others to chime in with their opinions. Onc's will like more light and less water than your Phals, but after you re-pot it, I'd keep it in the shady area with the Phals for a couple of weeks to let it recover. Then gradually move it to more light - or just move the curtain aside a little bit for it?
Those shriveling, weeping pseudobulbs do not look good to me, although otherwise, the plant has nice healthy looking leaves and roots. I'd be cutting out those pseudobulbs with a sharp, sterile knife asap, and dust the cuts with cinnamon after you're through. Again, though, please wait for the experts to chime in here.
Normally, Oncidiums shrivel up their pb's when they are asking for water, but they wrinkle lengthwise and stay the same color green, not like those. Are they squishy, too?
