This study aims to analyze the thermal output and downward heat loasses according to the pipe pitch of the floor heating panels for the design of a radiant floor heating system in a zero-energy apartment to compare the design heating load in zero-energy apartment housing unit. The thermal output and downward heat losses were analyzed according to the pipe pitches, flooring and pipe materials by using the universial single power function method in ISO 11855-2. The results showed that the heating load could be removed even if the pipe pitch of the existing radiant floor heating system is changed to around 350 mm as the thermal insulation and airtightness in the zero-energy apartment building has been greatly improved. The thermal output in individual heating was about 30% higher than that of district heating. In addition, it was found that it was necessary to consider the thermal resistance of flooring materials for the design of the radiant floor heating panel because it would affect the thermal output through the room air. When the lowerest floor was exposed to the outside air, downward heat losses greatly increased, so it would be necessary to increase the outside thermal insulation thickness for the energy saving during heating operation. |
