1. A heat transfer unit for use in a location where heat will be transferred by the unit from a heat source in an enclosure to ambient hazardous air, the heat transfer unit comprising:
a housing comprising
a first compartment, configured for coupling to and removing heat from the enclosure, the first compartment having therein
an evaporator,a motor, andany other potential ignition source within the heat transfer unit;a second compartment comprising
an ambient hazardous air inlet, an ambient hazardous air outlet, a condenser and an ambient air movement element located between the ambient hazardous air inlet and ambient hazardous air outlet, the ambient air movement element being located such that, during operation of the heat transfer unit, the ambient air movement element will move and cause ambient hazardous air to pass into the ambient hazardous air inlet, past coils of the condenser, and out the ambient hazardous air outlet; wherein the evaporator and condenser are coupled to each other via piping so as to collectively comprise a cooling circuit for passage of a cooling medium therebetween; wherein the motor is coupled to the ambient air movement element so as to cause the air movement element to move during operation of the heat transfer unit; and wherein the first compartment is sealed off from the second compartment such that, during operation of the heat transfer unit, the first compartment will be sealed off from the hazardous ambient air. |
