Abstract
An apparatus provides a high efficiency for refrigerator operation. The inclusion of a separate external evaporator and condenser that draws heat away from the common refrigerator condenser allows an increase in the intensity of the cooling process of the cooling agent, thereby diminishing electrical consumption, and decreasing the size and noise of the condenser. This is achieved by structuring the refrigerator condenser with the one tube for the cooling agent of the common refrigerator and another volume for evaporating the cooling substance of the external evaporator and condenser. Moreover, external system of natural cooling has a condenser that is located in the open air and connected to the evaporator with the help of vapor lines and condensed vapor lines.

A refrigerator condenser assembly, comprising:
- a refrigerator condenser pipe containing a refrigerator cooling agent;
- and
- an additional cooling system for cooling the refrigerator condenser pipe, comprising:
- an evaporator structure enclosing a volume adjacent to the refrigerator condenser pipe, wherein the volume contains an additional cooling substance that is a light boiling liquid, the evaporator structure with the cooling substance therein serving as an evaporator portion for the additional cooling system, the light boiling liquid receiving thermal energy from the refrigerator condenser pipe at the evaporator structure so as to transform the light boiling liquid into a gaseous state;
- a remote condensing unit located remotely from and above the refrigerator condenser pipe, the remote condensing unit condenses the additional cooling substance from the gaseous state to a liquid state;
- and
- vapor and condensed vapor lines that connect the remote condensing unit and the evaporator structure that convey the additional cooling substance in the gaseous state from the evaporator structure to the condensing unit and the condensed vapor line conveys the additional cooling substance from the condensing unit to the evaporator structure,
- a vapor block in the condensed vapor line to prevent vapor from flowing from the evaporator structure to the remote condensing unit through the condensed vapor line so that the additional cooling substance can circulate through the evaporator structure and the condensing unit and the vapor and condensed vapor lines only in a single circulation direction;
- the evaporator structure and the remote condensing unit and the vapor and condensed vapor lines forming a circulatory system that moves the additional cooling substance through the additional cooling system by gravity to provide cooling of the refrigerator condenser pipe when an ambient temperature at the remote condensing unit is at a predetermined temperature differential below a temperature at the evaporator structure.
