Blast Auxiliary Portable AC A mobile unit does not require a power-hungry cooling circuit using chemical refrigerants and an evaporator or compressor. Instead, the units use ice cubes, cooling batteries or cold water. This also allows the temperature in a room to be reduced considerably. This is achieved with these units by means of evaporative cooling. The physical fact is used that a certain amount of heat (energy) from a liquid creates a gaseous state of aggregation. The mobile air conditioners, such as the Blast Auxiliary Portable AC system, are equipped with practical functions.
