Recreational vehicle heat transfer apparatus

In a recreational vehicle having an attached refrigeration unit including heat-dissipating coils and heat-collecting coils, the refrigeration unit capable of transferring heat out of the recreational vehicle by moving air into the recreational vehicle through the heat-collecting coils by way of opposing first and second inlets of the refrigeration unit, apparatus comprising:

• a first evaporative cooler disposed adjacent the first inlet capable of pre-cooling air to the heat-dissipating coils by way of the first inlet, the first evaporative cooler including a housing supporting first media, a water source, and a valve coupled in fluid communication with the water source and the first media and movable by the thermostat control assembly between a closed position and an open position permitting water to move from the water source to the first media;
• a second evaporative cooler disposed adjacent the second inlet capable of pre-cooling air to the heat-dissipating coils by way of the second inlet;
• and
• a thermostat control assembly capable of sensing ambient temperature and activating the first and second evaporative coolers when the ambient temperature reaches a threshold ambient temperature providing pre-cooled air to the heat-dissipating coils.

In a recreational vehicle having an attached refrigeration unit including heat-dissipating coils and heat-collecting coils, the refrigeration unit capable of transferring heat out of the recreational vehicle by moving air into the recreational vehicle through the heat-collecting coils by way of opposing first and second inlets of the refrigeration unit, a method comprising steps of:

• disposing a first evaporative cooler adjacent the first inlet;
• disposing a second evaporative cooler adjacent the second inlet;
• associating with the first and second evaporative coolers a thermostat control assembly capable of sensing ambient temperature and activating the first and second evaporative coolers when the ambient temperature reaches a threshold ambient temperature providing pre-cooled air to the heat-dissipating coils by way of the first and second inlets;
• securing the first and second evaporative coolers to each other and to the refrigeration unit with straps.
