The inside of a Carnot refrigerator is maintained at a temperature of 277 K, while the temperature in the kitchen is 299 K. Using 3930 J of work, how much heat can this refrigerator remove from its inside compartment?
QS. An air-conditioner with a power input of 1.5 kW is working as a refrigerator (B-3) or as a heat pump (B' 4). It maintains an office at 20C year round which exchanges 0.5 kW per degree temperature difference with the atmosphere. There is a range of the outside temperatures for which this unit is sufficient a) Write the expressions that define the coefficient of performance (COP) for a refrigerator (B) and a heat pump (B) b) Calculate the maximum...
A Carnot refrigerator transfers heat from its inside (4.75 oC) to the room air outside (20.4 oC). (a) Find the coefficient of performance of the refrigerator. (b) Determine the magnitude of the minimum work needed to cool 5.61 kg of water from 20.4 to 4.75 oC when it is placed in the refrigerator.
A Carnot refrigerator is used in a kitchen in which the temperature is kept at 309 K. This refrigerator uses 296 J of work to remove 2890 J of heat from the food inside. What is the temperature inside the refrigerator? Kitchen TOH loc! Food in refrigerator
A real refrigerator works between two temperature reservoirs, one at 277 Kelvin, and one at 345 Kelvin. In order to maintain a constant heat flow, during one cycle 350 Joules of heat is transferred from the cold reservoir, while the net work in one cycle is 500 Joules. (a) Obtain the coefficient of performance for this refrigerator. (b) Compare the result in (a) with the ideal case. That is, what is the maximum coefficient of performance if this was an...

What is the possible maximum coefficient of performance for an ideal refrigerator operating between a reserve at a temperature of 2.0 K and another reserve at a temperature of 0.020 K?
1. (10) A refrigerator at home requires an electric power of 200W to operate. Temperature in the room is To=293K what is the temperature inside the refrigerator if the heat extracted by a working gas is five times greater than the work done to the working gas? 2. 10) Solve problem 1 as if it is a heat pump.
