How expensive is it to cool warm air from +25°C down to - 5°C ?

Hi

Hoping someone can help me as I need to know how much energy its going to take to cool air volume of 41.99m3/hr. from 25degC to -5degC then convert it to a daily dollar value. Power rate is 31.32 cents per kilowatt hour.

Thanks in advance

is 41.99m3/hr on hot side or cool side ???

If cool side of Air at 1013 mBar have density of 1.3166 kg/m3 and enthalpy shift from 424.17 kJ/kg on 25 degree to 393.99 kJ/kg on -5 degree C give difference of 30.18 kJ/kg and 41.99m3 -5 degree C air have weight of 55.284 kg and with 30.18 kJ/kg give 1668 kJ energy to remove from air per hour or 463.5 Watt if you using machine with COP 1.0

if you using machine with higher COP, you save more money.
