Abstract
This study clarifies the simulation on freezing of remaining water in the Z-trap set up in the PVC sewage bay to control malodor. It made use of commercial FEM LAB program(ver. 3.2) well known as a solution of the problems arising in the flow of various fluid, heat transfer and mass transfer. Simulation results under the temperature $-20^{\circ}C$ outwards show that the water in the Z-trap set up in the sewage bay to control malodor freeze in the 60cm under the ground level after 14 days in the wet ground, and after 17 days in the regular ground. On the other hand, if the soil is dry even after the 42 days does not go down below freezing. Therefore, the water in the Z-trap was confirmed that it does not freeze.
