The heat pump includes a compressor, indoor devices that heat or cool an indoor space, outdoor heat exchangers, and switching devices. The outdoor heat exchangers are configured to individually operate as a condenser or an evaporator depending on a ratio of heating to cooling of the indoor devices. When an operation mode is changed, continuous heating and cooling is performed without stopping the system.
