No, you cannot use ice-cold water as a replacement for refrigerant in a portable air conditioner unit. Refrigerant is a specialized substance designed to transfer heat efficiently. It undergoes a phase change from a gas to a liquid and vice versa, absorbing heat from the indoor air and releasing it outside.
Ice-cold water, on the other hand, cannot replicate the properties and functions of refrigerant. While it may initially provide a cooling effect, it cannot effectively absorb and transfer heat like refrigerant does. Additionally, using water instead of refrigerant can cause damage to the air conditioner and its components.
If your portable air conditioner unit requires refrigerant replacement, it is best to consult a professional technician who can safely handle the task. They will have the expertise to properly handle refrigerants and ensure that the air conditioner functions optimally.
