The kitchen fridge, also known as a refrigerator, is designed to keep the food and beverages inside cold. While it does remove heat from its interior to achieve this, it does not make the entire house cold. In fact, the process of refrigeration involves the transfer of heat from the inside of the fridge to the outside.
Refrigerators work by using a compressor and a refrigerant fluid to absorb heat from the interior of the fridge and release it into the surrounding air outside the appliance. This process cools down the contents of the fridge while warming up the surrounding air. However, the amount of heat released by the fridge into the kitchen is generally negligible and won't have a significant impact on the overall temperature of the house.
If you feel a slight increase in temperature around the fridge due to the heat it releases, it would be localized to the immediate vicinity of the appliance and not enough to cool down the entire house. The main purpose of the fridge is to maintain a cold environment inside it, not to cool down the rest of the living space. For cooling the entire house, you would need an air conditioning system or other cooling devices designed for that purpose.
