Title:
FLOW PATH SWITCHING VALVE AND AIR CONDITIONER WITH SAME
Document Type and Number:
WIPO Patent Application WO/2012/086746
Kind Code:
A1
Abstract:
Provided is an air conditioner performing dehumidification operation even if cooling operation is performed using a reduced amount of refrigerant circulation. When a flow path switching valve (51) is disposed at the inlet or the outlet of an evaporator for cooling having paths through which the refrigerant flows, if a first mode by a first path (21) is set, cooling can be performed using the entire evaporator, and if a second mode or a third mode is set, cooling can be performed by a portion of the evaporator by causing the refrigerant to flow to some of the paths. Accordingly, in the air conditioner provided with the flow path switching valve (51), when a control unit (8) switches the flow path switching valve (51) to the second mode in order to perform cooling operation, the refrigerant can flow only to a first indoor heat exchanger (40a) and a second indoor heat exchanger (40b), and as a result, only a portion of the indoor heat exchanger (40) serves as the evaporator. Accordingly, the use capacity of the indoor heat exchanger (40) is reduced. When the capacity of the indoor heat exchanger (40) is reduced without a change in the amount of air supply to the indoor heat exchanger (40), sucked air is dehumidified without a large amount of sensible heat being drawn from the sucked air.
