Abstract
An apparatus for heating and cooling includes a solar collector for transferring heat energy from incident solar rays to a liquid refrigerant material thereby changing a first portion to a gaseous state. An eductor-venturi reduces a pressure of the gaseous refrigerant material and a condenser removes the heat energy thereby changing the refrigerant material back to the liquid state. A heat exchanger associated with the condenser receives the heat energy removed from the refrigerant material. A float evaporator mounted in a cold chamber transfers heat energy from the atmosphere to the liquid refrigerant material thereby changing a second portion to the gaseous state and cooling the cold chamber atmosphere. A float actuated valve connected to the float evaporator is responsive to a level of the liquid refrigerant material in the evaporator for regulating a flow of the liquid refrigerant material into the evaporator.
