WebA refrigerator (or heat pump) absorbs heat Q c from the cold reservoir at Kelvin temperature T c and discards heat Q h to the hot reservoir at Kelvin temperature T h, while work W is … WebAs with heat pumps, work input is required for heat transfer of energy from cold to hot. The quality of air conditioners and refrigerators is judged by how much energy is removed by heat Q c from a cold environment, compared with how much work, W, is required.

WebApr 21, 2024 · A refrigerator performance is measured by the co-efficient of performance: Heat removed from the cold reservoir (ie inside) divided by the Work input: The CP … WebA simple heat pump has four basic components: (1) condenser, (2) expansion valve, (3) evaporator, and (4) compressor. In the heating mode, heat transfer Qc occurs to the working fluid in the evaporator (3) from the colder outdoor air, turning it into a gas. The electrically driven compressor (4) increases the temperature and pressure of the gas ... shutdown -r windows cmd

WebAug 12, 2024 · asked Aug 12, 2024 in Physics by Juhy (63.1k points) A refrigerator uses a power input of 2.5 kW to cool a 5°C space with the high temperature in the cycle as 50°C. The Q H is pushed to the ambient air at 35°C in a heat exchanger where the transfer coefficient is 50 W/m 2 K. Find the required minimum heat transfer area. WebThe basic mechanism of a refrigerator works like this: The compressor compresses the refrigerant vapor, increasing the temperature and pressure of the refrigerant vapor. The high-temperature and high-pressure refrigerant vapor dissipates heat to the ambient when it flow through the fin coil unit outside the refrigerator. WebA refrigerator is a physical device that makes use of mechanical work to transmit heat from a cold area to a hot area. What are the applications of a refrigerator? A refrigerator is used for the separation of gasses, condensation of gasses, dehumidification of air, and cooling for preservation. Test Your Knowledge On Refrigerator Heat Pump! thep48.cn
