How internal systems work
Wall mounted internal air conditioning systems are plumbed directly into your water supply. They use the cold water in a controlled manner to cool the air through the piping system. Unlike traditional air conditioning systems, water cooled units do not require an outdoor unit. The internal condenser is usually hidden within the property in a concealed space such as a cupboard or under the kitchen sink.
