Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2014/103172
Kind Code:
A1
Abstract:
An air conditioner (1), which is configured in such a manner that an outdoor unit (2) and indoor units (3) are connected via two connection pipes (11, 12) and an operation in which heating and cooling are mixed can be performed, wherein switching mechanisms (23) that switch the direction that a refrigerant flows through the connection pipes (11, 12) during a main heating operation is disposed in a first load region having a small cooling load and a second load region having a larger cooling load than the first load region. The air conditioner (1) is further configured in such a manner that, in the second load region, a low-pressure refrigerant flows from the indoor units (3) to the outdoor unit (2) via the second connection pipe (12), which is larger than the first connection pipe (11), thus minimizing a reduction in capacity due to pressure loss during the main heating operation.
