Multi type air-conditioner and control method thereof
摘要：
A multi type air conditioner comprises: an outdoor unit (10) including an outdoor heat exchanger (12) heat-exchanged with the outdoor air, a compressor (14) compressing a refrigerant, and a first four-way valve (16) and a second four-way valve (18) switching a refrigerant flow path; indoor units (20) performing at least one of cooling operation and heating operation; and a distributor (30) including a low pressure pipe (50) connected between the first four-way valve (16) and each of the indoor units (20), a high pressure pipe (52) connected between the second four-way valve (18) and each of the indoor units (20), and a refrigerant pipe (32) connected between the outdoor heat-exchanger (12) and each of the indoor units (20). 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 (52) is minimized in cooling operation, thereby improving cooling performance and cooling efficiency.
