Embodiment Construction

[0044] Next, an embodiment of the air conditioner 1 according to the present invention will be described.

[0045]

[0046] Such as figure 1 and figure 2 As shown, the air conditioner 1 of this embodiment includes: an indoor unit 2 installed indoors; an outdoor unit 3 installed outdoors; and a remote controller 4 (refer to image 3 ). The indoor unit 2 includes: an indoor heat exchanger 20; an indoor fan 21 disposed near the indoor heat exchanger 20; Figure 4 and Figure 5) the radiation heat exchanger 22 set; the indoor electric valve (valve mechanism) 23; and the indoor temperature sensor 24 for detecting the indoor temperature. Furthermore, the outdoor unit 3 includes: a compressor 30 ; a four-way switching valve 31 ; an outdoor heat exchanger 32 ; an outdoor fan 33 disposed near the outdoor heat exchanger 32 ; and an outdoor electric valve (pressure reducing mechanism) 34 . The indoor unit 2 and the outdoor unit 3 are connected through an annular refrigerant circu...

Abstract

In order to improve comfort, this air conditioner is provided with a refrigerant circuit having a compressor, an indoor heat exchanger, a radiant heat exchanger, a pressure reduction mechanism, and an outdoor heat exchanger. The indoor heat exchanger is disposed inside an indoor unit in such a manner as to face an indoor fan, and the radiant heat exchanger is disposed on the outer surface of the indoor unit. In addition, the air conditioner has an indoor electrically-operated valve for adjusting the amount of refrigerant supplied to the radiant heat exchanger. The air conditioner is controlled in such a manner that, when a refrigerant is flushed through the indoor heat exchanger to carry out warm-air heating, and the refrigerant is flushed through the radiant heat exchanger to carry out radiant heating, the opening of the indoor electrically-operated valve becomes larger after the frequency of the compressor drops.

Description

technical field [0001] The present invention relates to an air conditioner provided with an indoor heat exchanger, a fan, and a radiation heat exchanger. Background technique [0002] As an indoor unit of an air conditioner, an indoor unit including an indoor fan, an indoor heat exchanger arranged to face the indoor fan, and a radiation panel (radiant heat exchanger) arranged on the surface of the indoor unit is known. [0003] For example, in the air conditioner described in Patent Document 1, a radiation panel and an indoor heat exchanger are connected in series. When performing both warm-air heating and radiant heating, high-temperature and high-pressure refrigerant discharged from a compressor provided in the outdoor unit is supplied to the radiant heat exchanger, and then supplied to the indoor heat exchanger. This air conditioner controls the operating frequency of the compressor according to the room temperature when performing both warm air heating and radiant heati...
