Abstract

A heat pump system utilizing the domestic waste water was introduced into a gymnasium owned by Hokkaido Electric Power to elucidate the applicability of domestic waste water as a thermal source of heat pump in the cold region. The gymnasium is a two-storied concrete building with the floor space of 2292m{sup 2}. Ground water at temperatures from 10 to 20{degree}C is utilized for the water supply. Made to flow together as waste water, the dirty water and daily exhaust water are discharged at the rate of 100t/day into a river after passing through the septic tank. Higher by 5 to 15{degree}C than the atmospheric temperature, the discharging temperature is kept higher than 10{degree}C even during the very cold period. The domestic waste water is almost neutral in pH, and normal in both SS and BOD. The heat pump was utilized for two stages, i.e., thermal collection and temperature heightening. The capacity of a sewage storage tank tank was made to be 170m{sup 3} to meet the thermal load of 139000kcal/h in the gymnasium. The temperature of 15{degree}C could be kept during the air heating trial. The system is about 2 in coefficient of performance. The K-value of heat exchanger decreased  More>>

The K-value of heat exchanger decreased by about 30% after seven months of operation. Upon its overhauling, its K-value recovered to 2.37, so that it must be overhauled once a year. 5 refs., 15 figs. 4 tabs.}
