気調和機。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a refrigeration cycle that performs floor heating using a refrigerant, and is an air conditioner with a floor heating function suitable for keeping the amount of refrigerant enclosed to a small level.

縮機の信頼性にとって大きなマイナスとなる。A refrigeration cycle capable of performing floor heating using a conventional refrigerant is shown in FIG. 1 and will be described. 1 is a compressor, 2 is a refrigerant switching valve, 3 is a check valve, 4 is a floor panel that connects the check valve 3 in parallel, 5 is an indoor heat exchanger, 6 is a pressure reducing device for cooling, 7 is a pressure reducing device for heating device, 8 is a check valve connected in parallel with the heating pressure reducing device, 9 is an outdoor heat exchanger, 10 is an indoor fan, 11
is an outdoor fan. Thereby, the heating operation can be simultaneous operation of floor heating using the floor panel 4 and air heating using the indoor heat exchanger 5 and indoor fan 10, or independent operation of the floor heating by stopping the indoor fan IO. The cooling operation is the same as before. During heating operation, check valve 3
The high-temperature, high-pressure gas refrigerant from the compressor 1 passes through the refrigerant switching valve 2, passes through the floor panel 4, and heats the floor panel 4 with condensation heat.
enters the indoor heat exchanger 5, where the indoor fan 10 causes
Even more condensation makes your nose runny. During floor heating sole operation, the two-phase region refrigerant condensed by the floor panel 4 enters the indoor heat exchanger 5 and exits the indoor heat exchanger 5 only by natural heat radiation. In this heating operation, the internal volume of the floor panel 4 is larger than in the conventional cycle composed of the indoor heat exchanger 5 and the outdoor heat exchanger 9, and the amount of refrigerant enclosed is inevitably increased, which increases the reliability of the compressor. This is a big negative for sex.
本発明の目的は冷媒による床暖房を行なう冷凍サイクル
において、冷媒封入量を少なく抑えることが可能な床暖
房機能付空気調和機を提供することにある。An object of the present invention is to provide an air conditioner with a floor heating function that can suppress the amount of refrigerant sealed in a refrigeration cycle that performs floor heating using a refrigerant.

め、暖房運転時のみ室内熱交換機の内容積を減少する必
要がある。During heating operation, the internal volume of the floor panel is increased to the internal volume of a conventional refrigeration cycle, so the amount of refrigerant sealed increases. If this increase in the internal volume of the floor panel is adjusted by reducing the internal volume of the indoor heat exchanger, the amount of refrigerant sealed will not increase. Furthermore, during cooling operation, the same internal volume as before is required to ensure cooling capacity, so it is necessary to reduce the internal volume of the indoor heat exchanger only during heating operation.

続されている。An embodiment of the present invention will be described below with reference to FIG. Second
In the figures, the same numbers as in FIG. 1 indicate the same items. In Fig. 2, 12 is the front indoor heat exchanger on the windward side, 13
is a rear heat exchanger on the leeward side, and is connected in series with the check valve 14. The front heat exchanger 12 and the rear heat exchanger 13 are connected in parallel, and the floor panel 4 is connected to this.

器に溜まることもないのである。During heating operation, the refrigerant that has passed through the floor panel 4 passes only through the front indoor heat exchanger 12 on the windward side due to the check valve 14, so the internal volume of the refrigeration cycle during heating operation does not increase, and the cooling chamber is closed. The quantity also does not increase. In addition, the refrigerant flows through the heat exchanger 12 on the windward side, and the warm air warmed by this flows into the heat exchanger 12.
The refrigerant that warms the rear heat exchanger 13 does not accumulate in the leeward heat exchanger.

ることが可能である。。According to the present invention, during heating operation, the increase in the internal volume of the floor panel for floor heating is adjusted by dividing the indoor heat exchanger and using only a part of it, thereby suppressing an increase in the amount of refrigerant sealed. Therefore, it is possible to significantly improve the reliability of the compressor. .
