Answer :
The rate at which heat is being rejected from the air is 1.75 kW
In this scenario, the automotive air conditioner is producing a cooling effect of 1 kW while consuming 0.75 kW of power. This means that the air conditioner is removing 1 kW of heat from the air inside the car, and expelling it outside.
In order to calculate the rate at which heat is being rejected from the air, we can use the formula:
Heat rejected = Cooling effect + Power consumed
Heat rejected = 1 kW + 0.75 kW
Heat rejected = 1.75 kW
. This means that for every hour of operation, the air conditioner is removing 1 kW of heat from the air inside the car and expelling 1.75 kW of heat outside.
It is important to note that this calculation assumes ideal operating conditions and does not account for any losses or inefficiencies in the system.
