Abstract
A multi type air conditioner comprises: an outdoor unit including an outdoor heat exchanger heat-exchanged with the outdoor air, a compressor compressing a refrigerant, and a first four-way valve and a second four-way valve switching a refrigerant flow path; indoor units performing at least one of cooling operation and heating operation; and a distributor including a low pressure pipe connected between the first four-way valve and each of the indoor units, a high pressure pipe connected between the second four-way valve and each of the indoor units, and a refrigerant pipe connected between the outer heat-exchanger and each of the indoor units. Accordingly, flow resistance of a refrigerant is reduced in heating operation, thereby improving heating performance and heating efficiency, and the amount of refrigerant accumulated within a high pressure pipe is minimized in cooling operation, thereby improving cooling performance and cooling efficiency.
