Should refrigerants be operated at temperatures above or below their critical temperature?
The critical temperature of a refrigerant is the point at which it changes states. In a refrigeration scenario, this happens 2 times per cycle. The refrigerant is a liquid on the high pressure side, and below its critical temp. On the low pressure side it becomes a vapor (gas) and its above its crictal temp.
So the answer is both, depending on what side of the system you are on.

What does mean by thermostat?
A thermostat is a device that senses and regulates the temperature of a system, such as a heating or cooling system, to maintain it at a desired set point. It does this by controlling the flow of heat transfer media to maintain the set temperature.
Why do you need to aftercool compressed air?
Aftercooling compressed air is necessary to reduce its temperature after compression, as compressing air generates heat. Lowering the temperature of compressed air can help prevent damage to downstream equipment, improve air quality, and increase the efficiency of air-operated devices.
What is the transformation of energy of battery-operated radio?
In a battery-operated radio, electrical energy from the battery is transformed into electromagnetic waves by the transmitter circuit. These waves carry the audio signal to the radio's receiver, where they are converted back into sound waves that we can hear through the speaker.
How did a 1920s refrigerator work?
A 1920s refrigerator typically operated using a compressor that circulated a refrigerant through a system of coils. The refrigerant absorbed heat from inside the refrigerator, cooling the interior space. The compressor then compressed the refrigerant, raising its temperature and releasing the absorbed heat outside the refrigerator.
Hands moving on a battery operated click is an example of what kind of energy conversion?
The hands moving on a battery-operated clock is an example of electrical energy being converted into mechanical energy to drive the clock hands.
Why boiler is operated close to critical temperature?
Greatest efficiency at that temperature.
How are gases liquefied?
Gases are liquefied by cooling them below their critical temperature and applying enough pressure to reach their critical pressure. This process causes the gas molecules to come together and form a liquid state. This can be achieved using various methods such as compression or expansion.
What is the normal engine operating temperature for a 3306 cat engine?
The normal engine operating temperature, for a 3306 Caterpillar diesel engine, is 180 degrees. The engine should not be operated at temperatures above 200 degrees.
What is the gas pressure in car ac?
When not operated, around ambient temperatures (70psi), when turned on, low sides are mid 30's-mid 40's and the high side is 180-200psi depending on the outside temperature.
What is the difference between oven temperatures?
The difference between Fahrenheit and Celsius is easily calculated by any number of internet converters. http://www.stabb.com/tools/convert.HTML . The difference between cooking temperatures is less important then one might imagine. In the cooking industry we generally use 3 or 4 standard temperatures. 180 is the big one. it is equivalent to about 350 degrees and is basically used for everything. this is the temperature that most everything is cooked at, if the recipe or instructions don't ask for something else this is what you should use. in professional cooking often there wont be any mention made to temperature because it is generally understood that you cook at this temp "until done".
How hot does a multi fuel stove get?
A multi-fuel stove can reach temperatures between 300°F to 600°F (150°C to 315°C) depending on the type of fuel used, the stove design, and how efficiently it is operated. When burning high-energy fuels like coal or dry wood, the stove can achieve higher temperatures. It's essential to monitor the stove's temperature to ensure safe operation and prevent overheating. Always refer to the manufacturer's guidelines for specific temperature ranges.
What four things does the network of NOAA operated buoys record?
currents, temperature, salinity, wind and waves.by the jimpster
Is Alkaline better than lithium?
Depends on the usage. In low power drain devices operated mostly at room temperature, alkaline batteries are probably better. In high power drain devices sometimes operated at high or low temperatures, lithium is definitely better. It is best to use what the manufacturer of the device the battery will be used in recommends.
Should the temperature be 195 regardless of how old the car is?
Pre-computer operated vehicles could run cooler if needed.
How low in temperature should a commercial freezer be?
freezer temperature should be 8ca refrigerator for safety of food should be operated at 8 degrees or below to prevent contamination
What happens to the hull of a ship if it is operated for long periods of time in water temperatures that are freezing?
The metal gets cold, the water freezes over, and the ship gets stuck.
Can the optic nerve be operated on?
Yes, the optic nerve can be operated on to treat conditions such as tumors, inflammation, or to relieve pressure. However, it is a delicate procedure due to the critical function of the optic nerve in vision. Consulting with an experienced ophthalmologist or neurosurgeon is essential to determine the best course of action.
