Abstract
A heat-actuated air conditioner/heat pump is disclosed which includes a sealed, rotatable tube. The sealed tube contains a working fluid and includes an evaporator leg and a condenser leg, the condenser leg extending a greater distance from the axis of rotation than the evaporator leg. As the tube is rotated, a vapor pressure differential is created between the evaporator and condenser legs with the higher pressure in the condenser leg. Because of this pressure differential, the working fluid will evaporate in the evaporator leg at a lower temperature than that at which it will condense in the condenser leg. The evaporator leg thus can be used for cooling a stream of house air (house air conditioning) while the condenser leg rejects heat to a stream of ambient air. When all of the working fluid has evaporated, the system may be recharged for another cooling cycle by supplying heat to the condenser leg to drive the working fluid back into the evaporator leg. The sealed tube may also be operated as a heat pump for heating house air.
