【摘要】：對上海地區(qū)某高層住宅樓應用的地源熱泵系統(tǒng)的實際性能進行研究,檢測系統(tǒng)逐日、逐月及全年的空調和熱水能耗。結果表明:在現(xiàn)有入住率較低的情況下,3棟樓每戶年平均能耗分別為52.5、72.0和83.4 MWh;空調熱泵和熱水熱泵機組待機率分別超過了58%和81%;供暖、制冷和過渡季熱水能耗分別占總能耗的70%、55%和90%。熱泵機組長期低負荷運行且頻繁啟停,及水泵全年工頻不間斷運行是導致全年能耗偏高的主要原因。如何降低熱水系統(tǒng)能耗是系統(tǒng)節(jié)能的關鍵之一�？刹扇∷袩岜脵C組形成環(huán)網(wǎng)、水泵順序啟停和變頻運行,并根據(jù)熱水器內溫度設定熱水熱泵主機啟停等針對性措施,實現(xiàn)系統(tǒng)節(jié)能降耗。
[Abstract]:The actual performance of the ground source heat pump system applied to a high-rise residential building in Shanghai is studied, and the energy consumption of air-conditioning and hot water is detected on a day-by-day, a month-by-month and a year. The results show that the annual average energy consumption of the three buildings is 52.5, 72.0 and 83.4 MWh, respectively, and the energy consumption of the air-conditioning heat pump and the hot-water heat pump unit is more than 58% and 81%, respectively. The energy consumption of the hot water in the heating, cooling and transition season accounts for 70%,55% and 90% of the total energy consumption, respectively. The long-term low-load operation of the heat pump unit and the frequent start and stop of the pump and the uninterrupted operation of the power frequency of the water pump in the whole year are the main reasons leading to high energy consumption in the whole year. How to reduce the energy consumption of the hot water system is one of the key to the energy saving of the system. All the heat pump units can be adopted to form the ring network, the water pump is in sequence start-stop and variable-frequency operation, and the system can realize energy-saving and consumption-saving of the system according to the specific measures such as the start-stop of the hot-water heat pump host in the water heater.
