Cooling condition: Chilled water inlet/outlet temperature 12/7 ℃, ambient dry bulb temperature 35℃
Heating condition: Hot water outlet temperature 45℃, ambient dry bulb temperature 7℃, ambient wet bulb temperature 6℃

Application: Large scale air-conditioning systems pump this chilled water to coils in specific areas of, lets say, a high rise building. The air handling systems for each area open and close the water flow through it specific area keeping the air of the rooms at a desired temperature.
