Why refrigerators and freezers have plastic foam core?
Refrigerators and freezers have plastic foam core as it is the most resistant to the low temp inside the compartment,but even Teflon can be used
How do you measure refrigerator temperature?
Most refrigerators have a thermometer inside that will show the temperature. If there is not one, most stores sell refrigerator thermometers.
Why does the magnet stick to the refrigerator?
Because most refrigerators are made of ferromagnetic materials, and ferromagnetic materials are attracted to magnets.
What type of energy is used to run most refrigerators?
Electrical- there are a few that run on heat energy from gas or kerosene.
When is the most heat removed from the refrigerant in the condensing process?
When the maximum pressure of the refrigerant is achieved in the condensor and the maximum temperature differential is acheived between the condensor coil and the surrounding medium. (air, water, or other)
What is the most common refrigerant in household refrigerators?
R12
Function of expansion valve?
Metering device The metering device controls the flow of liquid refrigerant through the system. The liquid enters at a high-pressure, high-temperature, sub-cooled state and leaves as a low-pressure, low temperature, expanded liquid state. Accurator Piston and Thermostatic Expansion Valves are the most widely used metering devices. Accurator Pistons are widely used because of their low cost and flexibility. The piston can easily be changed to match the capacity of the condensing unit. The Thermostatic Expansion Valve (TXV) is the most efficient type of metering device. The TXV automatically adjusts the flow of the liquid refrigerant based on the superheat of the refrigerant leaving the evaporator coil. As the load on the evaporator increases, the TXV increases the flow of refrigerant. This maintains the proper superheat. The TXV is efficient throughout a variety of system operating conditions, while the accurator is efficient only under designed conditions.
What metering device is most common on apartment air conditioners?
Bulk
Why does my Air conditioner starts by blowing cold air then warm air?
Low on freon, a weak compressor, or a restriction in your metering device.
What metering device is the most efficient for heat pumps?
Thermostatic Expansion Valve (TXV, TEV). Any high efficient system requires one.
Which brand of refrigerators has the most compartments?
The brand of refrigerators that has the most compartments is Samsung. They have a Four Door Fridge. It has 4 separate compartments.
What is most likely the problem with my 2004 Mustang if its not blowing a lot of AC?
If the air flow is weak, the problem could be in your switch, blower motor resistor, blower motor, or cabin air filter - the details of your problem are very vague, and it makes it difficult to try diagnosing it from afar. If the air isn't cold, there are a multitude of possible reasons why - not enough refrigerant (usually due to a leak), too much refrigerant and/or PAG oil, blockage in the system, poor air flow through the condenser fins, faulty metering device, faulty compressor or compressor clutch, faulty high or low pressure switches, electrical faults, etc.
What causes the compressor to turn on and off rapidly on a 2008 Chrysler PT Cruiser?
Low refrigerant is most likely.Low refrigerant is most likely.
Is there dry ice in refrigerators?
No. Most refrigerators use a coolant system similar to air conditioners (which use freon).
Should you replace the coils when getting a new AC unit?
If you are talking about the indoor evaporator coil being replaced when you replace the outdoor condensing unit than yes. Reason being the two are a matched pair. Most of the time the older indoor A coils are fit with an accurator or cap tubes as a metering device for the refirgerant. The newer condensing units are based on the A coil with a TXV metering device. In short a mismatched system will never perfom as it is intended. However many contractors still try to sell only condenser replacements.
Do more Americans own side by side or top freezer refrigerators?
Most people own top freezer refrigerators. Only upper and middle-upper class people usually have side by side refrigerators.
What is the principle of air conditioning?
Evaporation is the primary principle. The three primary components of most residential air conditioners are: # Compressor # Condenser # Evaporator As the refrigerant is compressed in the compressor, lowering the temperatures required to change from liquid to gas and gas to liquid. This is an exothermic, or heat generating, process. The compressed refrigerant, still under pressure, passes through the condenser. For residential systems, this is the "fan in a box" part of the air conditioning system outside. The condenser is actually blowing heat away from the refrigerant. Because the refrigerant is pressurized, the temperature is low enough for the refrigerant to turn liquid. The evaporator is where the cooling actually happens. When the pressure is reduced, the refrigerant evaporates; it turns from liquid to gas. Evaporation is an endothermic, or heat absorbing, process. The refrigerant absorbs heat from the air around it. This leaves the air around the evaporator much cooler and ready to be blown into the house. (Most refrigerators operate using the same process.)
