Air source heat pumps are generally used to heat houses in Urla during winter. They typically have two heat exchangers. The one found in the exterior unit has a coil of tubing filled with a refrigerant. Since the refrigerant liquid is cooler than the surrounding air, heat is drawn into the coil from the surrounding. This warms the refrigerant so that it transitions to a gas. In this form, the refrigerant travels into the house to the heat pump's interior unit. Naturally, the heat is transferred from the refrigerant in the interior unit coil to the house. Consider a house equipped with an air source heat pump in a winter day at an outside temperature of 7 °C. The average room temperature inside the house is 22°C. The house is not well-insulated and therefore loses heat at a rate of 45,000 kJ/h. If the refrigerant temperature decreases by 5°C while it flows through the heat pump's interior heat exchanger unit, calculate the minimum flow rate of the refrigerant in kg/s required to keep…
