Abstract
A method for determining a pipe diameter of a liquid-side connection pipe in a refrigeration apparatus includes causing a computer to obtain a heating capacity, maximum heating load, and maximum cooling load; causing the computer to determine a pipe diameter of the liquid-side connection pipe by reducing a reference pipe diameter based on either a value obtained by dividing the maximum heating load by the maximum cooling load or a value obtained by subtracting the maximum heating load from the heating capacity; and installing the refrigeration apparatus using the liquid-side connection pipe having the determined pipe diameter.
