dc.description.abstract | In Korea two popular water distribution systems—the branch type and the separate type systems—have serious drawbacks. The branch type suffers from temperature instability while the separate type suffers from excessive piping. Neither of them re-circulates water. The system proposed in this paper utilizes a water-conserving piping system with a thermostat valve. This paper compares the proposed system with that of the separate type. Our findings show that the proposed system wastes less water. After re-circulating for 78-87 seconds, water is available at set point temperature (40°C). Also, when multiple water taps are in use, the average temperature deviation is less than 0.6°C. Moreover, the proposed system has 50% less flow rate than the separate type system. | en |
