Title:
AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2017/030076
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing an air conditioner can take measures against impact sound when switching a four-way switching valve and minimize decreases in heating performance prior to transitioning to defrosting operation. In this air conditioner (1), an indoor fan (35) operates during switching operation of a four-way switching valve (15). As a result, the operation sound of the indoor fan (35) covers the impact sound of the four-way switching valve (15) during switching operation and thereby makes it possible to prevent a user from being disturbed by abnormal noise. In addition, it is possible to minimize decreases in heating operation performance because there is no need to reduce the operating frequency of a compressor prior to transitioning to defrosting operation.
