Assume A Heat Pump With Reverse Operation Of The Carnot Cycle The Efficiency Of The Carnot Cycle Is Determined Only By 1 (123.68 KiB) Viewed 56 times

Assume a heat pump with reverse operation of the Carnot cycle. The efficiency of the Carnot cycle is determined only by the temperatures on the hot and cold sides. T, T₁ At this time, note that each temperature needs to be considered in Kelvin units. e=1- The low temperature side T₂ is 25°C indoors. The outside air on the high temperature side T₁ is 30°C or 40°C. Calculate the efficiency of the Carnot cycle in two cases. In the cooling operation, the heat on the low temperature side is pumped up to the high temperature side. When pumping the same amount of heat, the required work (electric power) is proportional to the efficiency. How many times does the power consumption increase when the outside temperature changes from 30°C to 40°C?
