摘　　要：学生公寓热水需求量大且用水时间较为分散,选择少污染且高效的热源形式,对高校的节能减排有重要的意义。空气源热泵辅助太阳能热水系统水温恒定,可全天候供应热水,满足阴雨天及冬季使用热水需求,智能化程度高,节能效果明显且项目回收周期短,可以在高校中推广使用。介绍山东某高校公寓实际运行的空气源热泵辅助太阳能热水系统及其控制原理;并通过对电热水器和单独采用空气源热泵制取热水方式的年耗电量计算,与实际运行项目的年耗电量比较,对其节能性进行分析。由于对系统各设备的启停采用了智能控制系统,能够对系统运行模式进行灵活调控,使得该系统比电热水器节电75%,比独立空气源热泵系统节电30%。根据2021年项目实际年收入,预计该系统回收周期为4.2年。The demand for hot water in student apartments is large,and the water use time is relatively scattered,so choosing a less polluting and efficient heat source is of great significance to the energy saving and emission reduction of colleges and universities.The hot water system of air source heat pump assisted solar has a constant water temperature,which can supply hot water all weather,meet the demand for hot water in rainy days and winter,has a high degree of intelligence,obvious energy-saving effect,and the project recovery cycle is short,and can be promoted in colleges and universities.This paper introduces the air-source heat pump assisted solar water heating system and its control principle in a college apartment in Shandong province.By calculating the annual power consumption of electric water heater and hot water production by air source heat pump alone,and comparing with the annual power consumption of the actual operation project,the energy saving performance is analyzed.Since the intelligent control system is adopted for the start and stop of each device in the system,the system can flexibly regulate the operation mode of the system,which makes the system save 75%electricity than the electric water heater and 30%electricity than the air source heat pump system.Based on the actual annual revenue of the project in 2021,the recycling cycle of the system is expected to be 4.2 years.
