What is the purpose of the coils under a refrigerator?
The purpose of the coils under a refrigerator are to allow the refrigerant to cool down before being turned back into a liquid. This allows the compressor to function properly.
Can a room be cooled by leaving the door of refrigerator open?
No, leaving the door of a refrigerator open will not cool a room, but will actually make the room hotter. A refrigerator cools its own interior by pumping heat to the heat exchange coils in the back (some models do not have exposed heat exchange coils, but the sides or back of the refrigerator have coils just underneath them, and they get hot). Those heat exchange coils pump heat into the room. Since the process is not 100% efficient, the amount of heat produced includes a certain amount of waste heat. As a result, pumping heat from one part of the room to another part of the room results in a net increase in heat.
What form of energy does a refrigerator produce?
In a refrigerator, electrical energy is converted into mechanical energy by a motor. The motor drives a compressor, and this compresses and heats the refrigerant. Mechanical energy is converted into thermal energy in this process. The hot refrigerant is cooled in the cooling coils behind or beneath the appliance, and the cooler gas is "sprayed" through an expansion valve connected to the cooling coils inside the unit. The releasing of the pressure of the refrigerant allows expansion, and with expansion comes cooling.
Why are the cooling fins at the back of the refrigerator usually painted black and have a rough surface?
Usually it is rough so anything in there or by the inside can be broken up, I think.
Where does the energy come from to warm the pipes at the back of the fridge?
Ammonia gas is compressed until it becomes very hot from the increased pressure. This heated gas flows through the coils behind the refrigerator, which allow excess heat to be released into the surrounding air.

Dude.. because copper is a insulators of heat so they prevent heat\warmth to reach through it thus letting the coils cool.

Why is your home refrigerator not cold but the freezer section is extremely cold?
There are several possible reasons why a home refrigerator may not be cold while the freezer section remains extremely cold: Thermostat issue: The thermostat controls the temperature settings for both the refrigerator and freezer compartments. If the thermostat is faulty or set incorrectly, it could result in the refrigerator section not cooling properly while the freezer section continues to chill. Damaged or blocked air vents: The refrigerator and freezer compartments are connected by air vents that allow cold air to circulate. If these vents are blocked by food items or damaged, it can disrupt the airflow and prevent proper cooling in the refrigerator section. Defective evaporator fan: The evaporator fan is responsible for circulating cold air throughout the refrigerator. If the fan malfunctions or stops working, it can lead to inadequate cooling in the refrigerator while the freezer section still receives cold air. Condenser coil issues: The condenser coils, located at the back or bottom of the refrigerator, release heat from the system. If these coils are dirty or covered in dust, they may not be able to dissipate heat efficiently, resulting in inadequate cooling in the refrigerator section. Refrigerant leak: A refrigerant leak can cause an imbalance in the cooling system, resulting in the freezer section becoming excessively cold while the refrigerator section remains warm. This is a more serious issue that may require professional repair. If you're experiencing this problem with your refrigerator, it is advisable to consult a qualified appliance technician to diagnose and fix the specific issue.

Is the depth of a refrigerator taken based on the unit dimensions or how far it protrudes from the wall?
Refrigerator depth is measured from the front of the cabinet (not including the handle) to the back of the coils. You will also need to allow for at least 1" clearance to the wall.
How do refridgerators work?
Refrigerators and air conditioners are heat pumps. They move heat from one place to a different place. They use a working fluid with a low boiling point to do this, e.g. hydrofluorocarbons like HF3C. This working fluid is compressed by a compressor until it liquifies. However it also becomes hot, so the compressed liquid is passed through radiator coils to dispose of the unwanted heat (typically on the back of a refrigerator or the outside part of an air conditioner). The liquid working fluid, now at about room temperature, passes through a small hole as it enters the cooling coils which are at low pressure. The working fluid evaporates inside the cooling coils, reducing their temperature. The gaseous working fluid is then compressed back to liquid by the compressor and the cycle continues.
How to Repair a Refrigerator?
The first thing that you should always check if your refrigerator is malfunctioning is your power. You can do this by opening your refrigerator door and checking to see if the light is on. Even if the light is not on, you should also listen to see of you can hear the motor humming. If you have been unable to see or hear any sign of life, you should check to see if the power cord is plugged into a power socket. If this does not work, you need to check the circuit breaker. Temperature Controls If there is nothing wrong with the power, then perhaps you should check your refrigerator’s temperature controls. In some cases, the controls can change easily. You need to make sure that it is set at the right temperature. If the controls have been moved accidentally, then you can make the proper adjustments. You can even use a permanent marker to make a note of where it needs to be. If you are worried that it may be accidentally moved again, you can use tape to make sure that the controls stay in place. This will prevent the controls from moving easily again. Coils In some cases, you may need to clean your refrigerator coils with a brush or vacuum. There may be too much dust and pet hair around your coils. If your coils are too clogged, there will not be enough airflow through the coils to allow your refrigerator to cool correctly. If you cannot find the coils behind the refrigerator, you can usually find them at the bottom front of your refrigerator. You will need to remove the kick plate that is found below the door. You may also need to make sure that nothing has fallen behind your refrigerator that may be blocking the coils. Running Fan If your refrigerator has the coils at the bottom, you may also need to make sure that the fan is running properly. You need to gain access to the panel that is normally found in the back of the refrigerator. Open the panel and look for paper, dust, or anything else that could potentially be keeping the fan from turning as it should. You might need to use your vacuum to clean this out.
Can you lay a refrigerator down for transport?
Most cannot be safely moved or even positioned on their sides or backs. Certainly, units with coils in the back should never be rested on their backs. Some units have fragile copper refrigerant lines that might be damaged by a shifting compressor if the unit is laid on its side. If you can, you should call tech support or customer service and ask them about your model. After transport you must be sure to leave the refrigerator upright for several hours upon reaching your destination before plugging it in and turning it on.
In a refrigeration system with chilled water running to coils what type of system is this?
Behind the crispers bins and sometimes under the cover for the lights in the back of the refrigerator you will find either a tank or a coil of plastic one quarter inch pipe which is supplied with water from another line exiting the refrigerator from the back . There is another line that comes from the tank or coil of one quarter inch plastice pipe into the ice maker and the chilled water dispenser on the front of the refrigerator
