Regulating Temperature of The Refrigerator

Regulating Temperature of The Refrigerator; There is only one temperature control button on a one-door refrigerator, but on a two-door refrigerator there are two buttons for temperature regulation. These differences can be confusing to the layman. Let's discuss how to regulate the temperature in a single door refrigerator and a two door refrigerator.

One Door Refrigerator Temperature Control

The two-door refrigerator only has one temperature control button. This button is generally found on the part of the freezer, which is the part used to make ice. This button is connected directly to the thermostat, which is a device that is used as a temperature sensor as well as a switch to turn the compressor on and off. For how to set this button, read more in the article How to Set a Refrigerator Thermostat.

The thermostat on this one-door refrigerator will detect the temperature in the evaporator, which is the place used to make ice. The end of the capillary tube (a pipe with a small diameter) is attached to the evaporator. Therefore, the temperature control button on a single door refrigerator will regulate the evaporator temperature.

Double Door Refrigerator Temperature Control

In a two-door refrigerator there are two temperature control buttons, one button on the top and one button on the bottom. Then how do we manage it? Let's discuss.

Two Door Refrigerator Bottom Temperature Control Button

In a two-door refrigerator, the top button when turned will not feel heavy (very light). This button is only connected to a damper. This damper functions as an opening and closing the air duct. What air, why is there a duct, and where does it go? Maybe this is a good question.

In a two-door refrigerator, the cooling that occurs is indirect cooling. This cooling occurs because the evaporator (the cold part) does not directly cool the media (food or beverage). But this evaporator will cool the air that passes through it. This air will be blown through the evaporator by an air fan which causes the air to cool. It is this cold air that is blown into the upper refrigerator (freezer) and used to make ice or to freeze meat.

The air from this cooling chamber will be sucked in and passed to the evaporator again so that the air will always be cold. This air circulation will continue to cool food or drinks in the refrigerator (freezer). This air circulation in the cooling room (upper door) will stop if the temperature of the lower door has been reached and defrost occurs.

In addition to being circulated in the freezer compartment, this cold air will also be channeled into the lower room which is used to cool vegetables, food, or drinks but not until frozen. Very little cold air is channeled into the lower chamber, while the room is larger than the upper chamber (freezer). Therefore, the air temperature in this basement is not too cold and cannot freeze food or drink.

The temperature control button at the top (freezer) is what functions to adjust the amount of air that will be circulated to the lower room. Namely by adjusting the width of the narrow damper.

Two Door Refrigerator Bottom Temperature Control Button

The temperature control button located on the bottom rung is connected to the thermostat. Therefore, whether or not the cooling process stops or the compressor turns on or off will be influenced by the temperature in the lower refrigerator chamber. As long as the lower room temperature setting has not been reached, the compressor will continue to run to carry out the cooling process even though everything in the upper room (freezer) has frozen.

Perhaps this very brief explanation will help to understand why on a double-door refrigerator there are two temperature control buttons. So hopefully this article is useful.
