The present invention relates to a calculation method of input amount of liquid for cooldown and computer-readable recording medium with computer program for executing the same on a computer. According to an embodiment of the present invention, the calculation method of the input amount of the liquid for cooldown comprises: a step of calculating a vaporized amount of a unit droplet (1) by using a change in a radius (r) of the unit droplet (1) of the liquid for cooldown (10) falling as a first input amount is inputted into a cargo warehouse (100); a step of repeating the step of calculating the vaporized amount of the unit droplet (1) until a reference point of time, and calculating the total vaporized amount of the unit droplet (1); a step of multiplying the total vaporized amount of the unit droplet (1) by the total number of the unit droplets (1) and calculating the total vaporized amount of the liquid for cooldown (10); a step of calculating the internal temperature of the cargo warehouse (100) after the first input amount of the liquid for cooldown (10) is inputted into the cargo warehouse (100) by using the total vaporized amount of the liquid for cooldown (10); and a step of, when the internal temperature of the cargo warehouse (100) is the same as a target internal temperature of the cargo warehouse (100), determining the first input amount of the liquid for cooldown (10) inputted into the cargo warehouse (100) as the final input amount of the liquid for cooldown (10). The present invention aims to provide a calculation method of input amount of liquid for cooldown and computer-readable recording medium with computer program for executing the same on a computer, which are capable of rapidly and precisely calculating the input amount of the liquid for cooldown into a cargo warehouse. 본 발명의 일 실시예에 따른 쿨다운용 액체의 투입량의 계산 방법은 화물창(100) 내에 제1 투입량이 투입되어 낙하하는 쿨다운용 액체(10)의 단위 액적(1)의 반지름(r)의 변화를 이용하여 상기 단위 액적(1)의 기화량을 계산하는 단계; 기준 시점까지 상기 단위 액적(1)의 기화량을 계산하는 단계를 반복하여 상기 단위 액적(1)의 총 기화량을 계산하는 단계; 상기 단위 액적(1)의 총 기화량에 상기 단위 액적(1)의 총 개수를 곱하여 상기 쿨다운용 액체(10)의 총 기화량을 계산하는 단계; 상기 쿨다운용 액체(10)의 총 기화량을 이용하여 상기 화물창(100)에 쿨다운용 액체(10)의 제1 투입량이 투입된 이후의 상기 화물창(100)의 내부 온도를 계산하는 단계; 상기 화물창(100)의 내부 온도가 상기 화물창(100)의 목표 내부 온도와 동일할 경우, 상기 화물창(100)에 투입된 상기 쿨다운용 액체(10)의 제1 투입량을 상기 쿨다운용 액체(10)의 최종 투입량으로 결정하는 단계를 포함한다.
