In a refrigerating machine heat rejected is
Did you know?
WebWhen we are interested in the heat energy supplied to the high-temperature space, the device is called a heat pump. In general, the term heat pump is used to describe the cycle as heat energy is removed from the low-temperature space and rejected to the high- temperature space. WebQR = the heat rejected to the cold body W = the work done . e = the thermal efficiency . 1'] = the temperature of the Source of heat ... Refrigerating Machine and Reversed Carnot Cycle 11 . PROBLEMS (1) A reversed Carnot cycle is used for refrigeration and rejects 1,000 kW of heat at 340 K while receiving heat at 250 K. Determine (a) COP, (b ...
WebMar 23, 2024 · The heat rejected to the surroundings equals the heat absorbed from the cold body or refrigeration produced plus the work done or mechanical energy consumed. … WebA Direct Water-Cooled System with Cooling Tower is an effective cooling system for industrial applications. It uses a closed-loop system to transfer the heat generated by the machinery to the cooling tower. The water is then cooled by the heat exchange process, and returned to the machinery for reuse. This system is known for its energy ...
WebAssuming that the machine operates on the reversed Carnot cycle, calculate: (a) The COP of the refrigerator. (b) The refrigerant effect per kW of input work. (c) The heat rejected to the condenser. ii- A compressor manufacturing company manufactures one model of compressor used for air conditioning applications. WebHeat rejected by the condenser (qcond) [kJ/kg] Work done to drive the compressor (wcomp) [kJ/kg] Coefficient of Performance (COP) of the system, either as a refrigerator or as a heat pump. As with the Steam Power Plant, we find that we can solve each component of this system separately and independently of
WebThe temperature in a refrigerator evaporator coil is -6 °C and that in the condenser coil is 22 °C. Assuming that the machine operates on the reversed Carnot cycle, calculate the COPref, the refrigerating effect per kilowatt of input work, and the heat rejected to the condenser. Suggested Answers: [9.54; 9.54 kW; 10.54 kW] Expert Answer
WebRefrigeration Cycle Heat flows in direction of decreasing temperature, i.e., from high-temperature to low temperature regions. The transfer of heat from a low-temperature to high-temperature requires a refrigerator and/or heat pump. Refrigerators and heat pumps are essentially the same device; they only differ in their objectives. slow oofWebJul 13, 2024 · Heat rejection is the excess heat from a cooling system and starts when the cooling tower heat load is reached.
