Title: | Compact and fast temperature-response heat pump water heater | Authors: | Huang B.J. Lin F.H. |
Issue Date: | 1997 | Publisher: | ASME, New York, NY, United States | Source: | American Society of Mechanical Engineers | Abstract: | A compact and fast temperature-response heat pump water heater was designed using multiple tanks and a sequential control device. The supply tank was heated as a priority by a freon-line switching device to increase the temperature recovery speed. A dual-tank prototype with 100-liter capacity was built and tested. The experimental results show that the time for temperature recovery of the supply tank from 42 °C to 54 °C reaches 10-20 minutes and COP reaches 2.0-3.0 during various seasons. The prototype tests show that an energy saving around 50%-70% as compared to the electrical water heater can be obtained. The hot water discharge efficiency of the heat pump is 0.912. |
