抄録

For the purpose of evaluating the performance of water saving fixture, water saving and energy conservation effects of thermostatic mixing faucet and shower head with stop valve were examined by object experiment. The effect of thermostatic mixing faucet compared with two valve faucet was that thermostatic mixing faucet could save water when adjusting hot water temperature and flow rate to optimum condition. The effect of shower head with stop valve was that hot water could be saved by using stop valve on shower head to stop hot water easily when unnecessary. As a result of object experiment, water was saved 1.0L by using thermostatic mixing faucet when hot water temperature and flow rate were adjusted each time to optimum condition. Hot water was saved 14.1L by using shower head with stop valve. Hot water was reduced by 27.3% compared with using normal shower head.
