Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air conditioner that is mainly capable of adding a floor heating function to a heat pump type air conditioner.

Conventional technology As shown in Japanese Utility Model Publication No. 56-32859, a technology has been developed in which a floor heating panel is connected to a separate air conditioner to enable floor heating and ventilation heating during heating. .

Problems to be Solved by the Invention However, in such a conventional configuration, the installation work of the floor heating panel is complicated and involves floor construction, which requires installation by a specialized contractor.

In view of the above-mentioned conventional problems, the present invention provides an air conditioner whose configuration can be simplified without sacrificing the advantages of the prior art.

Means for Solving the Problems In order to solve the above problems, the present invention includes a compressor, an indoor heat exchanger, a pressure reducing device, an outdoor heat exchanger, and a cycle switching means for switching between a heating cycle and a cooling cycle. The refrigeration cycle is provided with a subunit having a three-way switching valve that switches the refrigerant flow path between cooling and heating, and the subunit includes:
A planar carpet equipped with a refrigerant circuit is connected via a connector that can be attached and detached with one touch.

Effect: With this configuration, the planar carpet can be attached and detached freely, improving ease of construction and storage. Furthermore, if the carpet is made flexible, it can be conveniently stored compactly by rolling it up or the like.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is a refrigeration cycle diagram showing one embodiment of the present invention. In the figure, the refrigeration cycle includes a compressor 1, a four-way switching valve 2, a three-way switching valve 3, a self-sealing type removable connector 4, a flat carpet 5, a check valve 6, an indoor heat exchanger 7, and a depressurizer. It is constructed by connecting a heat exchanger 8 and an outdoor heat exchanger 9, respectively. Here, A is an outdoor unit of the air conditioner, B is an indoor unit, and C is a subunit. In the figure, four-way switching valve 2
and the three-way switching valve 3 indicate the heating side, and the refrigerant flow path during heating is from the compressor 1 to the four-way switching valve 2, the three-way switching valve 3, the connector 4, the planar carpet 5, the check valve 6, The pressure reducer 8 and the outdoor heat exchanger 9 are in the direction of the solid line in the same figure.

The refrigerant flow path during cooling is from the compressor 1 to the four-way switching valve 2, the outdoor heat exchanger 9, the pressure reducer 8, the indoor heat exchanger 7, and the three-way switching valve 3 in the direction of the broken line in the figure. . The three-way switching valve 3 cyclically disconnects the connector 4 from the cooling low pressure to prevent condensation. Therefore, by adding the subunit C and the flat carpet 5 to the existing separate air conditioner, an air conditioning system is created that utilizes the indoor unit B for cooling and the flat carpet C for heating.

Next, FIG. 2 shows an installation diagram according to an embodiment of the present invention. The figure shows an example in which an air conditioner is installed in a living room, and an outdoor unit A, an indoor unit B, a subunit C, a connector 4, and a flat carpet 5 are connected. Here, since the connector 4 is detachable, the planar carpet 5 may be removed during the cooling period.

Effects of the Invention As described above, according to the present invention, with the above configuration, by adding subunits and a flat carpet, an air conditioner can be constructed using an indoor unit for cooling and a flat carpet for heating. Therefore, a floor heating system can be configured by simply adding it to an existing separate air conditioner. Furthermore, the low pressure side of the air conditioner is separated from the planar carpet by the three-way switching valve, so there is no possibility of condensation forming on the connector. Furthermore, the connector is self-sealing and can be attached and detached with one touch, so it can be removed and stored during the summer.

As described above, the present invention has a wide range of advantages such as improved comfort, ease of construction, and ease of attachment and detachment.

Furthermore, it is obvious that the present invention is not limited to separate type air conditioners but can also be applied to integrated type air conditioners.
