How does dichlorodifluoromethane help to keep the temperature in a refrigerator down to freezing temperature?
All refrigerants remove and reject heat in the same way they just do so at different temperature and pressure relationships, for example, water at sea level "boils" or changes state at or above 212F, we can control the boiling point by adding or reducing the pressure exerted upon it. Water in a 30" vacuum will "boil" at room temperature. We can increase the boiling point or temperature by increasing pressure above ambient which is how an autiomotive radiator operates, the radiator cap holds 3 to 12 lbs of pressure and this determines the boiling point. Refrigeration works this same way, R 22 refrigerant at 70 psi will always be at 40F and above or below t will boil or condense. Refrigerant "boils" to remove heat and "condenses" to reject the heat outdoors.
You answered you own question: at freezing. At or near 32 degrees F your pump should be turned to keep water moving. moving water doesn't freeze. It is important that any expo…sed pipes, filter and pump have moving water at freezing as this water will freeze first and cause the item to crack. That's expensive as compared to the few cents it costs to operate the pump. Water starts to freeze at 32 degrees. So it best to turn pump on at approx. 35 degrees & leave on until the tempt. rises to 35
Freon is the registered name for a number of products containinghalocarbons. These refrigerants undergo a process where itcondenses into a liquid and evaporates into a solid, …losing asubstantial amount of heat in the process. Once it's cold enough,the gas is channeled through coils that allow it to absorb heatfrom the air in the fridge.
Generally you want your refrigerator to be no more than 42 degrees and no less than 38 degrees (or things will start to freeze).
fridge temp should not raise above 8, idea fridge temp should be around 3 or 4.
You should keep foods out of the danger zone to prevent bacteria from forming on foods. Bacteria can form on foods in the danger zone after just an hour. The danger zone is un…der 145 degrees and over 45 degrees.
Keep and serve it at room temperature.
At least one degree above freezing?
The best fresh food temperature is 40 degrees Farenheit. If it's any colder then the food is likely to freeze, and any warmer then the food won't keep as long or as safely.
Shouldn't ran in locations under 55 deg. F.
It depends on many things refrigerator, how long you have it open, what you set it at, etc.
temperature keep low the temperature of the refrigerator
3 to 5 Celsius
How does freon help to keep the temperature in a refrigerator down to keep the to freezing temperature?
The refrigerant itself doesn't do all of the work... heat and humidity is also drawn out of the passenger compartment by components of the AC system. In a nutshell, the refrig…erant absorbs heat drawn from the passenger compartment, and cycles through the AC system. It is pressurized, which causes it to heat up even further. When it gets to the condenser, the heat is exchanged to the ambient air through the condenser fins. The refrigerant cools down rapidly and cycles back to the evaporator. By the time it reaches the evaporator, it is extremely cold. The blower fan blows air across the condenser, thus delivering cool air into the passenger compartment. That's a simplified version of it, but covers the essential parts of it.
