| description | An air conditioning apparatus includes an outdoor device that is configured to circulate refrigerant and that includes a compressor, an outdoor heat exchanger and three pipes, a high pressure gas pipe, a low pressure gas pipe and a liquid pipe, a plurality of indoor devices configured to circulate water, and a heat exchange device connecting the outdoor device with the indoor device. The heat exchange device includes a heat exchanger configured to exchange heat between the refrigerant and the water, and a switch device configured to control flow of refrigerant between the indoor devices and the heat exchanger. The switch device comprises a liquid guide pipe connecting the heat exchanger to the liquid pipe, high and low pressure guide pipes connected to the high and low pressure gas pipes and joining at a joining point, and a refrigerant pipe connecting the joining point to the heat exchanger, and comprising a pressure equilibrium pipe branched from the refrigerant pipe and being connected to the low pressure guide pipe to allow pressure equalization between the high pressure refrigerant and the low pressure refrigerant in the refrigerant pipe when an operation mode of the heat exchanger is switched. |
