Description

[Detailed description of the invention] This invention relates to an air conditioner.

Conventional heat pump type air conditioners are often used to dry laundry because they blow hot air into the room, but if you try to use it to dry laundry during the mid-season or summer months, it will ruin the room! Therefore, the purpose of this invention is to perform drying and dehumidification without additional heating in the summer or mid-season, in addition to air conditioning. Our goal is to provide an air conditioner that can.

An embodiment of the present invention will be explained based on the drawings. The drawings show a refrigerant circuit diagram of an air conditioner according to the embodiment.

1 is a compressor, 2II'i four-way switching valve, 3 is an outdoor heat exchanger, 5ql is an indoor heat exchanger of 1, and 6 is a JI2 indoor heat exchanger, which are connected in sequence, and N1 is an indoor heat exchanger. A parallel circuit consisting of a throttling device 7 and an on-off valve 8 is inserted between the inner heat exchanger 5 and the second indoor heat exchanger 6, allowing outdoor heat exchange! I3 and j
Between the indoor heat exchange fs5 of ll, the throttle device 4 and the on-off valve 9
A parallel circuit is inserted.

And outdoor heat exchanger 3. The indoor heat exchanger 5 of $1 and the indoor heat exchanger 6 of j12 are equipped with blowers 10, 11, and 12t, respectively.Next, the operation of this air conditioner will be explained. First, during cooling operation, #-i on-off valve 8 is opened and on-off valve 9 is opened.
Therefore, the specific refrigerant discharged from the compressor 1 is transferred from the four-way switching valve 2 to the outdoor heat exchanger 3 to the throttle device 4 to the first
Both $1 and 1X20 indoor heat exchanger 5.6 in the sink in the route of indoor heat exchanger 5 → on-off valve 8 → second indoor heat exchanger 6 → four-way switching valve 2 → compressor 1 The cooling function is achieved by using an evaporator and the outdoor heat exchange @3 as an M# device.On the other hand, during heating operation, the four-way switching valve 2 is switched.

Compressor l] The discharged refrigerant is transferred to the four-way switching valve 2 → second indoor heat exchanger 5-i11 closing valve 8 → indoor heat exchanger 5 of $I11 → throttle device 4 → outdoor heat exchanger 3 →Four-way switching valve 2
→ Let it flow through the path of compressor I, and use both the first and N2 indoor heat exchangers 5.6 as condensers, and outdoor II heat exchange! The heating function is achieved by using I3 as an evaporator.

Next, when performing the drying and dehumidifying function during the intermediate and summer seasons, the on-off valve 9t is opened and the on-off valve 8 is closed, so that the refrigerant discharged from the compressor 1 is transferred to the four-way switching valve 2t-
then enters the second indoor heat exchanger 6, where the blower 12
The refrigerant is liquefied by the indoor air that is blown onto it and gives condensation heat to the air, so the air that has passed through the second indoor heat exchanger 6t has a temperature considerably higher than room temperature.

The pressure is reduced by the throttling device 7, which enters the JII indoor heat exchanger 5, where it cools and dehumidifies the indoor air blown by the blower 11, and the refrigerant evaporates into a gaseous state, which opens and closes the air. At this time, the rotation of the blower 10 corresponding to the outdoor heat exchanger 3 is stopped to avoid heating the room. At the same time, it reduces power loss. Here, the butterfly that exerts the drying function is to utilize the high temperature blown air that has passed through the second outdoor heat exchanger Is6. However, the first indoor heat exchanger 5 cools the air to a low temperature, so if this air is properly minxed, the indoor air as a whole will be slightly higher than room temperature. With this configuration, the result is not only cooling and heating 11, but also
Functions such as drying and dehumidifying laundry can be performed without unnecessary heating during the mid-season and summer months, allowing heat pump air conditioners to be used effectively throughout the year.

As described above, the air conditioner of the present invention includes a compressor, an outdoor heat exchanger having one end connected to one end of the compressor, and one end of the outdoor heat exchanger having one end connected to the other end of the outdoor heat exchanger. A parallel circuit of a connected first throttle device and a $1 on-off valve, and a first indoor heat exchanger whose one end is connected to the other end of the parallel circuit of the first throttle device and a lil on-off valve. , a parallel circuit of the IX2 throttling device and the IIE2 on-off valve connected to the other end of the indoor heat exchanger of this joint 1, and a parallel circuit of the Jll2 throttling device and the N2 on-off valve. One end of the circuit is connected to the other end of the circuit, the other end of the circuit is connected to the other end of the compressor, and then the indoor heat exchanger #I2, the compressor, the outdoor heat exchanger, and the Since it is equipped with a four-way switching valve inserted between the indoor heat exchanger (No. 2), in addition to heating and cooling, it is also possible to perform drying and dehumidification during the summer or mid-season without unnecessary heating.
