PROBLEM TO BE SOLVED: To provide an air conditioner which can selectively perform, in cooling operation either a cooling operation with preference to temperature and another cooling operation with preference humidity by switching, increase a dehumidifying amount at the time of cooling operation with preference to humidity and reduce consumption of electrical power. SOLUTION: This heat pump type air conditioner is constructed in such a manner that a filter 4, an indoor side heat exchanger 6, and a cross-flow fan 7 are arranged in an air passage 5 connecting a front surface suction port 2a, upper surface suction port 2b and outlet port 3 of a main body 1 so as o constitute a freezing cycle communicating with a compressor, a four-way valve, an outdoor heat exchanger, an electronic expansion valve and an indoor heat exchanger in sequence through a refrigerant pipe. In this case, a part of the indoor heat exchanger is shut off with a shut-off plate q during the cooling operation with preference to humidity, the electronic expansion valve is throttled to increase a dehumidifying amount, In turn, since the shut-off plate 9 and the electronic expansion valve are released during the cooling operation with preference to temperature and the heating operation, the prior art cooling or heating capacity can be maintained. In addition, during the cooling operation with preference to humidity, a dehumidifying amount is increased, resulting in that a comfortable feeling can be attained even if the temperature is not lowered down to a set temperature for the cooling operation with preference to temperature and so power consumption is reduced. |
