The present invention relates to multi-mode switch type air heat pump system. More specifically, the present invention is not required to have a machine room, and is able to be installed outdoors and to be operated and controlled by automatically switching the operations of air-conditioning, heating, and hot water supply by using a single unit so as to be suitable to the features. Air heat and water heat can be simultaneously used as a heat source. Operations, such as independent air-conditioning, independent heating, independent hot water supply, synchronous air-conditioning and heating, defrosting, and the like, can be separately performed by using a single compressor so as to increase the efficiency of heat pump system. The optimal operation efficiency and safety are ensured by using various safety devices. The system is simply and conveniently controlled and operated by PLC control. A plate around an air heat exchanger in which an outdoor blower fan is installed is made of copper rather than aluminum, thereby preventing the plate from corroding due to the inhaled air and achieving the effects of sterilization and service life extension. |
