For a refrigerator let us consider the following quantities: The absolute value of the amount of heat that a refrigerator absorbs from the cold reservoir (its internal part): |Q₁| The absolute value of the amount of heat that the refrigerator releases to the environment: |Q₂1. We can state that: a) 1Q₁1=1Q₂1 b) 1Q₁1>1Q₂1 c) IQ₂|>1Q11 d) whether | Q₁ | is greater than, less than or equal to Q₂ | depends on the performance of the cooler.
