When a person enters his house, which is completely closed in summer, he sees that the temperature is 34°C. After turning on the air conditioner, the temperature of the house becomes 22 °C within 15 minutes. Since the efficiency coefficient of the air conditioning system is 3.2, a) the electrical power drawn by the system, b) heat dissipated to the environment, and c) Assuming that it works 8 hours a day and the electricity price is 0.6 TL per kWh, find its cost for 4 months. Assume that the entire mass inside the house is equivalent to 1000 kg of air. For air, take Cv = 0.73 kJ/kgK, Cp= 1.0051 kJ/kgK.

3) When a person enters his house, which is completely closed in summer, he sees that the temperature is 34°C. After turning on the air conditioner, the temperature of the house becomes 22 °C within 15 minutes. Since the efficiency coefficient of the air conditioning system is 3.2,
a) the electrical power drawn by the system,
b) heat dissipated to the environment, and
c) Assuming that it works 8 hours a day and the electricity price is 0.6 TL per kWh, find its cost for 4 months. Assume that the entire mass inside the house is equivalent to 1000 kg of air. For air, take Cv = 0.73 kJ/kgK, Cp= 1.0051 kJ/kgK.
