1. A refrigerant based heat exchange system, the system comprising:
- a furnace heat exchanger;
an evaporating heat exchanger connected in a refrigeration circuit in which a compressor circulates refrigerant between a condenser and an evaporator coil;
wherein both the furnace heat exchanger and the evaporator coil include heat exchange surface areas and wherein air flow from a source of forced air is used to provide a heat exchange effect over the heat exchange surface areas; and
means for temporarily removing at least a selected one of the heat exchange surface areas in response to the detection of a passive heat pipe phenomenon in the refrigeration circuit.

Abstract
The present invention comprises an improved refrigerant based heat exchange system useful in air conditioning and refrigeration applications. The refrigerant based heat exchange system detects the presence of a passive heat pipe phenomenon in the refrigeration circuit and responds by either temporarily shutting off the flow of refrigerant in the circuit, or by temporarily removing the evaporator coil of the air conditioning portion of the system from the path of a forced air flow.
