Window Refrigerator

Abstract

A refrigerator having its heat exchanger outdoors. In one embodiment, a thermos is attached to the front of a window air conditioner. In another embodiment, the refrigerator has gated conduits to allow cold outdoor air into the refrigerator. The refrigerator has a compressor that circulates refrigerant in an auxiliary evaporator adjacent to the refrigerator compartment to freeze the water in the refrigerator at night and to allow the ice to keep the refrigerator cold. In another embodiment, the refrigerator is combined with a heat pump such that the outdoor heat exchanger of the heat pump and the outdoor heat exchanger of the refrigerator are in close thermal contact. Another embodiment includes a heat pump having a second evaporator near the refrigerator compartment to cool the inside of the refrigerator compartment and heat the home simultaneously by transferring the heat from inside the refrigerator to the indoors.

I claim: 
     
         1 . A combination of a window in a building having an inside and an outside, a device comprising an air conditioner passing through the window and having a front side toward the inside of the building, which front side has a control panel, and a thermos attached to the front of the air conditioner, which thermos has a rear wall facing the air conditioner, which rear wall contains an opening of such size as to allow cooled air from the air conditioner to enter the thermos. 
     
     
         2 . A combination of an opening between indoors and outdoors in a building having an inside and an outside and a refrigerator device, in which the refrigerator device has a cooling compartment, a door, an evaporator coil and a condenser coil wherein the condenser coil is outdoors, and a heat pump device, which heat pump device has a compressor, an indoor heat exchanger, and an outdoor heat exchanger wherein the outdoor heat exchanger of the heat pump is in thermal contact with the condenser coil of the refrigerator device. 
     
     
         3 . The combination of  claim 2 , wherein the opening is a window. 
     
     
         4 . The combination of  claim 2 , wherein the evaporator coil and the cooling compartment are inside the refrigerator device. 
     
     
         5 . A combination of an opening between indoors and outdoors in a building having an inside and an outside and an air conditioner having an evaporator coil, a time-sensitive device and a condenser coil wherein the condenser coil is outdoors, wherein the evaporator coil is adjacent to a reservoir wherein the reservoir is adjacent to a heat-conducting grate for air passage and contains heat-conductive phase-change material inside the reservoir, and wherein the time-sensitive device controls the operation of the evaporator coil so that the evaporator coil produces a solidified phase change in the phase-changing material in the reservoir at night when ambient temperature outdoors is colder than during day and the solidified phase-change material will later be used to cool the heat-conducting grate during day when ambient outdoor temperature is warmer than during night. 
     
     
         6 . The combination of  claim 5 , wherein the opening is a window. 
     
     
         7 . The combination of  claim 5 , wherein the evaporator coil and the reservoir are inside the air conditioner. 
     
     
         8 . The combination of  claim 5 , wherein the heat-conducting grate is an air duct. 
     
     
         9 . The combination of  claim 5 , wherein the phase change material is water and the solidified phase change material is ice. 
     
     
         10 . The combination of  claim 5 , wherein the air conditioner is an evaporative cooler.
