Abstract
An air conditioner suitable for use in a hazardous environment. The air conditioner, which may be of the conventional window type, is modified in such a manner that sparks are either eliminated, suppressed or contained to the extent that there is no danger of igniting an atmosphere that may contain an excess of dangerous particles. Any switching required in the electrical circuit is done by solid state devices, or with open contacts that carry such low power that sparking cannot occur, with the main load of the air conditioner being carried by the solid state device. The air conditioner is designed to withstand hostile elements such as salt spray from the ocean without excessive corrosion. A bypass valve is included to prevent frost collection on the evaporator coils if the air conditioner is unattended for long periods of time.
