側熱交換器８と同じ作用をさせるようにしている。As shown in FIG. 7, the refrigerant cycle of the air conditioner includes a compressor 4, a four-way valve 5, an outdoor heat exchanger 6, and a pressure reducing device 7.
Then, the indoor heat exchanger 8 is sequentially connected to the piping, and the four-way valve 5 is connected to perform cooling/heating operation. ? At the same time, the refrigerant vibe 9 branched from the indoor heat exchanger 8 is made to have the same effect as the indoor heat exchanger 8.

を汚損してしまうという欠点がある。That is, during heating operation, the refrigerant vibrator 9 acts as a condenser in the same way as the indoor heat exchanger 8.
The front panel 1 is heated to constitute a radiant panel. However, during cooling operation, the refrigerant vibrator 9 acts as an evaporator like the indoor heat exchanger 8, so the front panel 1 is cooled, and moisture in the air forms water droplets in front of the front panel 1. This has the disadvantage that it drips from the front panel 1 onto the floor and stains the carpet, for example.

Further, between the refrigerant passage 15 and the indoor heat exchanger 8, a long first shutoff valve 17 is provided on the indoor heat exchanger 8 side, and a long first shutoff valve 17 is provided for discharging the refrigerant.
5. A second on-off valve 18 is provided in parallel with the 117i1!1 valve 17 to allow the refrigerant to flow to the four-way valve 5 side.

、パネル＋温風運転、パネル＋冷風運転になる。In other words, if the compression Ia4 is of the normal type, it is turned on.
It is turned off, and if it is an inverter type, it is frequency controlled. In addition, if only panel operation is used, for heating, high pressure
There is a risk of an abnormal drop in low pressure during cooling, and to prevent this, the temperature sensor 19 or 20 detects this.For example, when the temperature reaches approximately 60°C during heating operation, or 0°C during cooling operation, the panel + hot air operation is activated. , it becomes panel + cold air operation.

凝縮器として作用する。In the case of warm air + panel operation, which is the operation mode during heating operation, the on-off valve 17 opens and the inter-n valve 18 opens. As shown in FIG. 4, the refrigerant flows through the four-way valve 5 -> refrigerant passage 15 -> first chamber 111 valve 17 -> indoor heat exchanger 8, so the refrigerant passage 15 receives heat from the indoor side. Like exchanger 8, it acts as a condenser.

In addition, the air sucked in from the suction port 12 by the air blower 13i16 passes through the suction side air passage between the front panel 11 and the indoor heat exchanger 8, is heat exchanged by the indoor heat exchanger 8, and becomes hot air. The airflow passes through the blow-off side air passage between the indoor heat exchanger 8 and the blow-off port 3, and is blown out from the blow-off port 3 into the room.

にする。In the case of operation mode panel operation, the indoor blower of Akebono 16 is stopped or super-stopped, the warm air heating function is stopped,
The front panel 11 is heated by high-temperature cold water flowing through the refrigerant passage 15. Since the front panel 11 radiates heat by natural convection heat transfer and radiant heat transfer, the heat exchangeability is low and the temperature of the front panel 11 increases considerably.However, the front panel 11 is provided with a panel temperature sensor 19. , the frequency (H7) of the compressor is controlled according to the detection signal of the panel temperature sensor 19, and the temperature rise of the front panel 11 is kept within a predetermined set value range. If the compressor is a regular type, the temperature rise on the front panel will be controlled by turning it on and off.

できる。In the case of the operation mode cold air + panel operation during cooling operation, the refrigerant is transferred to the indoor heat exchanger 8→
The refrigerant flows through the first on-off valve 17 → refrigerant passage 15 → four-way valve 5, and the front panel 11 is cooled. The temperature of the front panel 11 is detected by a panel temperature sensor 19, and freezing of the front panel can be prevented by controlling the compressor.
運転モードパネル運転の場合には、室内ファンを止め、
冷風冷房機能を停止し、冷媒通路１５を流れる低温冷媒
により前面パネル１１を冷却する。In the case of operation mode panel operation, stop the indoor fan,
The cold air cooling function is stopped, and the front panel 11 is cooled by the low-temperature refrigerant flowing through the refrigerant passage 15.

The temperature of the front panel 11 drops considerably, but the front panel 11 is equipped with a panel temperature sensor 1-19, and the frequency of the compressor changes depending on the detection signal of the panel temperature sensor 19. i(
H,) to prevent the front panel from freezing.
なＪ３、冷媒通路１５に冷媒を流さないようにするには
、開開弁１７を開じ、開開弁１８を開く。J3, to prevent the refrigerant from flowing into the refrigerant passage 15, open the on-off valve 17 and open the on-off valve 18.

損することもなくなる。As a result, the refrigerant does not flow into the refrigerant passage 15, but only into the indoor heat exchanger 8. Therefore, the front panel 11 is not cooled, moisture in the air does not adhere to the front surface of the front panel 11 in the form of water droplets, and there is no possibility of staining the jutan or the like.

１〔Ｉられる。Further, in an air conditioner that uses the front panel only for heating operation, the opening/opening valve may be a check valve. In this case, the refrigerant in the refrigerant passage 15 is blocked on the inlet side by a check valve,
Since the outlet side communicates with the low pressure side, the refrigerant is recovered to the low pressure side of the compression 114, and no refrigerant accumulates in the refrigerant passage 15. Therefore, the refrigerant in the main circuit tends to be insufficient, the capacity of the indoor heat exchanger 8 decreases due to excessive superheating, frosting occurs on the inner unit due to excessive superheating, and overheating of J3 and compressor 4 occurs. Effect 6 such as prevention of
