In order to further improve the convenience of the air-conditioning indoor unit, a valve which can be opened and closed by the remote control of the air conditioner can be arranged on a heating and radiating pipeline or an external connecting pipeline in the shell of the air conditioner to carry out on-off operation on a radiating system, and a manual valve can be installed to carry out manual opening and closing. When a heater needs to be used in winter, the valve is opened, hot water flows to circulate for heat dissipation, and when an air conditioner needs to be used for refrigeration in summer, the valve is closed, so that the cold energy of the air conditioner heat pump system is prevented from being influenced.
Furthermore, in order to improve the heat dissipation efficiency in winter heating use, a circulating pump is arranged at the water inlet pipe end or the water outlet pipe end of the heating heat dissipation pipeline. The circulation frequency of hot water in the fin radiator is accelerated, so that the radiating efficiency is improved.
The air inlet and the air outlet of the original air-conditioning indoor unit, the installation positions of the fan and the fin radiator are not changed, only a set of heat dissipation pipeline for heating is added in the original fin radiator, the heat dissipation pipeline is communicated with an indoor heating pipeline, indoor heating is realized by utilizing the efficient heat dissipation efficiency of the fin radiator of the air-conditioning indoor unit in winter, occupation of an installation radiator and a radiator in the background technology to an indoor space is avoided, meanwhile, the air-conditioning indoor unit is basically idle in winter, the installation cost of the radiator or the radiator is reduced, and multiple purposes are achieved.
