空调热水一体机制热兼制热水性能研究

Performance of air-conditioner-water-heater in warming with water heating mode

为了解决空调热水一体机在冬季制热时要同时热水连续用水要求与室内供暖要求的问题,就必须对空调热水一体机制热兼制热水模式的控制方式进行研究。首先,对现有的控制方式进行了分析,提出了一种新的控制方式,并进行了试验研究,得出了一些重要的实验数据。通过对实验数据的分析表明,空调热水一体机在此运行方式下能有效地保证热水与供暖的连续性,同时也提高了机组的能效比。

In order to solve the problem that air-conditioner-water-heater provide both continuing hot water and heating in winter,it is necessary to study the control strategy of air-conditioner-water-heater under heating and hot water mode.Based on an analysis of several existing control methods,a new control strategy was proposed and experimented.Results show that with this new control strategy,the sysyems can provide both continuing hot water and heating in winter at the same time.The COP of the system can also be enhanced.
