Performance of an air-conditioning water heater system with four modes.

Author(s) : LIU F., ZHUANG R., CHEN B., et al.

Summary

The working principles and the basic features of a domestic air conditioning water heater system are introduced in this paper. The air conditioning water heater system can be operated in four modes: cooling with heating water, heating water only, cooling and heating. Comparatively, the system can provide much better energy performance and higher equipment utilization throughout a year, cause less thermal pollution than the heat-pump water heater and the domestic air conditioner. A prototype with four modes was assembled and its operation performance was tested with the ambient temperature from -7 to 43°C, especially when frosting. The results indicate that the new system can save energy through multi-duties, and it can work stably under the four work modes with high efficiency. Compared with other system models, the new system also includes air-conditioning unit and water heater unit, but with fewer components and better reliability. Based on a common air conditioner, this system can offer a practicable solution coupling domestic air conditioner and water heater parts. It will change the markets of both air conditioner and water heater equipment.
