• How does an air-cooled portable air conditioner work?
  Air-cooled portable air conditioners are intended to be rolled into a room near the source of the heat. For spot cooling applications, you point the nozzles at the spot that you want to keep cool. For room cooling applications, the nozzle direction is not as important. Since the air conditioner is inside or near the space requiring cooling, you must duct out the warm air that the air conditioner produces. In an office environment this is typically done by ducting the condenser air from the top of the unit up to special ceiling tile that directs the air to the main building cooling system's return air plenum above the ceiling tiles. As the cool air from unit offsets the heat being produced in the room, the temperature in the room will begin to drop. The capacity of the unit, the amount of heat being added to the room, and the size of the room will determine how much the temperature will drop.
• How does an water-cooled portable air conditioner work?
  Water-cooled portable air conditioners are intended to be rolled into a room near the source of the heat. They are intended for room cooling only. Water-cooled units cannot be ducted and do not use nozzles like their air-cooled counterparts. Since the air conditioner is inside the space requiring cooling, you must remove the heat that is produced by the air conditioner. Water cooled units use water instead of air to remove this heat. The unit requires a water supply, water return, and a place to drain condensate. As the cold air from the cooling side of the unit offsets the heat being produced in the room, the temperature in the room begins to drop. The actual temperature drop is determined by the capacity of the unit, the amount of heat being added to the room, and the size of the room.
• What is the difference between a water-cooled and air-cooled portable air conditioner?
  Both types of units are totally self contained air conditioners with refrigerant and compressors. Air conditioners need a way to reject the heat from the room. Air-cooled portables use air to reject the heat out of the room by ducting the unit above the ceiling tiles. A water cooled unit uses water to reject the heat. So, there has to be a water supply and a hot water return. This can be accomplished with chilled water loop, condenser water loop, or process water loop.
