A control liquid pump 16 for circulating the control liquid is provided in the middle of 5. The indoor unit 2 will be described below.

Reference numeral 21 denotes a casing of the indoor unit 2, 22
Is an air suction port through which indoor air is sucked, 23 is a filter provided downstream of the air suction port 22, 24 is a blower provided downstream of the filter 23, and 25 is provided downstream of the blower 4 for dehumidification and cooling An air conditioning unit 26 for performing the above is a utilization side heat exchanger that is disposed in the air conditioning unit 25 and regulates the temperature and humidity of the control liquid flowing from above to below.

The use side heat exchanger 26 is located at the upper part of the air conditioner 25 and has an inlet side header 27 into which the control liquid from the cooler 6 flows, and an outlet side header from which the control liquid flows out to the heat exchanger 5. 28, and a plurality of semi-permeable membranes 30 similar to the semi-permeable membrane 12 of the regenerator 4, which are provided between the inlet-side header 27 and the outlet-side header 28, and are provided between the facing semi-permeable membranes 30.

An air flow path 33 is formed. Reference numeral 34 denotes an outside air introduction duct. An outside air suction port 35 at one end of the duct 34 is opened to the outside of the room, and the other end is opened between the air suction port 22 of the indoor unit 2 and the filter 23. A damper 36 that opens every predetermined time during operation of the blower 24 is provided in the outside air introduction duct 34. Reference numeral 37 denotes an opening / closing controller for the damper 36, which includes a timer (not shown).

The outdoor unit 1 and the indoor unit 2 configured as described above are provided with a control liquid outgoing pipe 38 from the cooler 6 of the heat source unit 1A to the inlet side header 27 of the utilization side heat exchanger 26 and an outlet side. It is connected to the heat exchanger 5 from the header 28 by a control liquid return pipe 40. The operation of the air conditioner during dehumidifying and cooling operations will be described below.

At the time of dehumidifying and cooling operation, the control liquid pump 1
By the operation of 6, the control liquid circulates as shown by the solid arrow in FIG. Then, the thin adjustment liquid (hereinafter referred to as a rare adjustment liquid) flowing out from the indoor unit 2 flows to the heat exchanger 5 through the adjustment liquid return pipe 40, and the high temperature adjustment liquid from the regenerator 4 is transferred to the heat exchanger 5. After heat exchange, the temperature rises and flows to the heater 7.

The rare adjustment liquid is heated by the high-temperature heat source from the heat source unit 1A in the heater 7, further rises in temperature and flows to the regenerator 4. The diluted adjustment liquid that has flowed into the inlet-side header 10 of the regenerator 4 flows through the flow path 13 toward the outlet-side header 11. Since the partial pressure of the dilute control solution is higher than the partial pressure of water vapor around the flow path, while the control solution flows through the flow path 13, part of the water in the dilute control solution permeates the semipermeable membrane 12 as water vapor. ,
It moves to the outside air side of the flow path 13. Evaporation of the moved water is promoted by the air flowing around by the operation of the blower 14, and the partial pressure of water vapor around the regenerator 4 is increased by the flow path 13.
It is kept lower than the dilute control solution.

While flowing through the flow path 13, moisture is absorbed by the semipermeable membrane 12
The concentrated control solution (hereinafter referred to as the concentrated control solution) whose concentration has increased due to the decrease in the amount of water after passing through the heat exchanger 5 flows to the heat exchanger 5 and exchanges heat with the rare control solution from the indoor unit 2 to lower the temperature. It flows to the heat source machine 1A. The concentrated adjusting liquid that has flowed to the heat source unit 1A is cooled by the cooler 6, and the temperature thereof decreases, and the concentrated adjusting liquid having a temperature higher than the conventional temperature, for example, at 25 ° C., flows into the indoor unit 2 through the adjusting liquid outgoing pipe 38.

In the indoor unit 2, the concentrated liquid flows through the use side heat exchanger 26, and the indoor air is blown by the operation of the blower 24 as indicated by the broken line arrow.
Is sucked into the indoor unit 2 through the filter 23, dust and the like are filtered by the filter 23, and the dust and the like flow around the use-side heat exchanger 26. In the use side heat exchanger 26, the concentrated adjusting liquid flows from the inlet side header 27 toward the outlet side header 28 through the flow path 31. In the use-side heat exchanger 26, the water vapor partial pressure of the concentrated liquid is lower than the water vapor partial pressure of the surrounding air, so that the water vapor contained in the air flowing around the semipermeable membrane 30 is semipermeable from the surface of the semipermeable membrane 30. It permeates through the membrane 30, moves to the flow path 31 side, and is absorbed by the concentration adjusting liquid. Then, the water vapor of the air flowing around is reduced and the humidity is reduced to be dehumidified, and is cooled when passing through the use side heat exchanger 26, for example, the temperature is about 25 ° C.
The air having a humidity of about 45% is blown out from the air outlet 32 into the room.

Further, in the indoor unit 2, the opening / closing controller 3
The damper 36 is opened, for example, every predetermined time by the operation of 7, and the outside air is sucked into the indoor unit 2 along with the indoor air by the operation of the blower 24, and the temperature and humidity are adjusted as described above and blown out into the room. . The diluted control liquid which has absorbed water in the utilization side heat exchanger 26 and has become thin flows through the control liquid return pipe 40 to the outdoor unit 1, and the heat exchanger 5 raises the temperature in the same manner as described above.

According to the above-mentioned embodiment, the low-concentration concentrated liquid flowing from the cooler 6 flows through the utilization side heat exchanger 26,
It is possible to dehumidify the room air while absorbing the water from the room air through the semipermeable membrane 30 by the water absorption effect of the concentration adjusting liquid. As a result, it is possible to supply dehumidified air to the room without significantly reducing the temperature, and especially when the humidity is high and the temperature is relatively low, such as in the rainy season, the air that is dehumidified and the temperature is almost the same as the indoor unit It can be supplied from 2 to the room and keep the room comfortable.

Further, the concentrated adjusting liquid cooled by the cooler 6 of the heat source unit 1A is sent to the indoor unit 2, and the concentrated adjusting liquid dehumidifies the indoor air and flows through the use side heat exchanger 26. Since the cooling is performed by the concentrated adjusting liquid, the adjusting liquid can be used for both humidity adjustment and cooling, and the piping between the outdoor unit 1 and the indoor unit 2 can be simplified, which facilitates installation work. It can also be simplified.

Further, since the waste heat of the cooling water or the exhaust gas from the heat source unit 1A is used as the heating source of the regenerator 4, the operating efficiency can be improved and the operating cost of the air conditioner can be reduced. Can be suppressed to In addition, the semipermeable membrane 12 is used for separating water from the regulated liquid in the regenerator 4 in which the outside air flows around, and the semipermeable membrane 30 is used for the use side heat exchanger 26 in which the room air flows around. As a result, it is possible to avoid the control liquid circulating between the outdoor unit 1 and the indoor unit 2 from coming into direct contact with the air, avoiding mixing of impurities such as dust into the control liquid, and using the control liquid for a long period of time. In addition, it is possible to avoid a decrease in the circulating amount of the regulated liquid or a blockage of the regulated liquid circulation path due to impurities, and it is possible to simplify the maintenance management of the air conditioner.

Further, the control liquid that has flowed from the regenerator 4 to the heat exchanger 5 exchanges heat with the control liquid having a low temperature that has flowed from the outdoor unit 2 when flowing through the heat exchanger 5, and the temperature drops and cools. Since it is sent to the cooler 6, the cooling capacity in the cooler 6 can be reduced, and the temperature of the control liquid that has flowed from the outdoor unit 2 is raised in the heat exchanger and sent to the heater 7. The heating capacity of the air conditioner 7 can be reduced, and as a result, the operating efficiency of the air conditioner can be further improved.

The second embodiment will be described in detail below with reference to FIG. 2, the same components as those in FIG. 1 are designated by the same reference numerals, and detailed description thereof will be omitted. The heat source unit 1A is, for example, an air-cooled absorption type refrigerator similar to that of the first embodiment, and heats the regulated liquid for heating the regulated liquid by an evaporator in which high-temperature refrigerant vapor flows from a high-temperature generator during heating operation, for example. It operates as a container 6A.

Further, 41 is a high temperature chamber formed airtight with the outside, and a water pool 4 formed under the high temperature chamber 41.

Is connected to the heat source unit 1A via the heat source pipe 18,
By operating the heat source unit 1A, high temperature refrigerant vapor from the high temperature generator or high temperature exhaust gas from a burner provided in the high temperature generator circulates as a heat source fluid.

The absorber 44 has an inlet-side header 45 into which the adjusting liquid flows in and an outlet-side header 46 into which the adjusting liquid flows out.
And a plurality of semi-permeable membranes 47, for example, under the trade name GORE-TEX, provided between the inlet-side header 45 and the outlet-side header 46, and the control liquid flow path is provided between the semi-permeable membranes 47 facing each other. 48 are formed. Further, for example, a replenishment pipe 50 for replenishing city water is connected to the high temperature chamber 41, and city water is replenished from the replenishment pipe 50 to the liquid pool 42. 51
Is an opening / closing valve provided in the middle of the supply pipe 50, and the opening / closing valve 51 is opened / closed based on a signal from a liquid level detector 52 such as a float switch provided in the liquid reservoir 42.

Further, 53 is the outlet side header 4 of the absorber 44.
6 is a control liquid pipe from 6 to the control liquid heater 6A. Further, the indoor unit 2 has the same configuration as that of the first embodiment described above, and the control liquid outgoing pipe 3 is provided between the control liquid heater 6A of the heat source unit 1A and the inlet header 27 of the use side heat exchanger 26.

The operation of the air conditioner during humidification and heating will be described below. During the humidifying and heating operations, the high-temperature heat source fluid flows from the heat source unit 1A to the water heater 43, and the water in the liquid pool 42 is heated. And the puddle 42
Water evaporates and the water vapor partial pressure of the gas phase portion 41A of the high temperature chamber 41 is kept high. Further, by operating the control liquid pump 16, the control liquid circulates as shown by the solid line arrow in FIG.
Then, the concentration adjusting liquid flowing from the indoor unit 2 to the absorber 44 flows from the inlet side header 45 to the outlet side header 46. Since the partial pressure of water vapor around the absorber 44 is higher than the partial pressure of the concentration adjusting liquid flowing in the flow passage 48, the water vapor in the vapor phase portion 41A permeates from the surface of the semipermeable membrane 47 to the flow passage 48 to adjust the concentration. It is absorbed by the liquid.

As described above, when the water vapor in the gas phase portion 41A is absorbed by the concentrated absorption liquid and the water in the liquid pool 42 evaporates, the liquid level lowers and reaches, for example, the lower limit water level.
Detects a drop in the liquid level and outputs an open signal to the on-off valve 51. The open / close valve 51 is opened by this open signal, the city water is supplied to the liquid pool 42, and the water surface rises. Then, for example, when the upper limit water level is reached, the liquid level detector 52 outputs a closing signal to the open / close valve 51, the supply of city water is stopped, and the liquid level is kept substantially constant.

The dilute control liquid, which has become thinner by absorbing water vapor, flows to the control liquid heater 6A through the control liquid pipe 53,
When heated, for example, a dilute control solution at 40 ° C is passed through the control solution piping 3
It flows to the indoor unit 2 via 8. In the indoor unit 2, while the rare adjustment liquid flows through the use side heat exchanger 26,
By operating the blower 24, the indoor air is sucked into the indoor unit 2 from the air suction port 22 as shown by the broken line arrow as in the first embodiment, and the dust and the like are filtered by the filter 23 so that the use side heat is removed. Flows around the exchanger 26.

In the heat exchanger 26 on the use side, the dilute control liquid flows from the inlet side header 27 toward the outlet side header 28 in the flow path 31.
Flowing through. In the use side heat exchanger 26, since the partial pressure of the dilute control liquid is higher than the water vapor partial pressure of the surrounding air, water permeates from the dilute control liquid in the flow path 31 through the semipermeable membrane 30 and the surface of the semipermeable membrane 30. Move to. Then, the water on the surface of the semipermeable membrane 30 evaporates and is contained in the air flowing around the use side heat exchanger 26,
Humidified, for example, the temperature is about 25 ° C and the humidity is about 50%.
Is blown out into the room from the air outlet 32.

In the indoor unit 2, the opening / closing controller 3
By the operation of 7, the damper 36 is opened, for example, every predetermined time, the outside air is sucked into the indoor unit 2 together with the indoor air, the temperature and the humidity are adjusted as described above, and the air is blown out into the room. The concentrated control solution that has become thicker by releasing water in the use-side heat exchanger 26 flows to the outdoor unit 1 through the control solution return pipe 40, absorbs water in the absorber 44, and heats the control solution heater 6A. Indoor unit 2
Flows to

According to the above-mentioned embodiment, the rare control liquid having a high temperature and high humidity which is absorbed by the absorber 44 and heated by the control liquid heater 6A flows through the use side heat exchanger 26 to heat the indoor air. In addition, moisture can be supplied to the room air to humidify it by the action of releasing water from the dilute control liquid via the semipermeable membrane 30. As a result, it is possible to supply dehumidified air to the room while increasing the temperature, and particularly to supply air with high temperature and humidity from the indoor unit 2 to the room even in a dry season when the temperature is low such as winter. Can be kept comfortable.

Further, the rare earth adjusting liquid heated by the adjusting liquid heater 6A of the heat source unit 1A is sent to the indoor unit 2, and the indoor air is humidified by the rare earth adjusting liquid flowing through the use side heat exchanger 26. Since the indoor air is heated, the control liquid can be used for both humidity control and heating, and the piping between the outdoor unit 1 and the indoor unit 2 can be simplified, which simplifies the installation work. It can also be achieved.

Furthermore, since the waste heat of the cooling water or the exhaust gas from the heat source unit 1A is used as the heating source of the water heater 43 in the high temperature chamber 41, the operating efficiency can be improved and the outdoor unit 1 and the operating cost of the air conditioner can be slightly suppressed. Further, since the semipermeable membrane 47 is used for absorbing the moisture of the control liquid in the absorber 44 and the semipermeable membrane 30 is used for the use side heat exchanger 26 in which the room air flows around, the outdoor unit. 1 can avoid direct contact of the control liquid circulating between the indoor unit 2 and the indoor unit 2 with impurities such as dust and the like, and the control liquid can be used for a long period of time as well as the impurities.

Further, a fifth bypass pipe 75 that bypasses the temperature controller 60 is connected between the outlet-side heat source pipe 18 and the inlet-side heat source pipe 18 of the temperature controller 60 via a fifth control valve 76. .

The operation of the air conditioner during dehumidifying and cooling operations will be described below. During the dehumidifying and cooling operation, the discharge side of the first switching valve 61 is switched to the heat exchanger 5 side, the control liquid flows as shown by the solid arrow 77, and the inflow of the second switching valve 63. The side is switched to the heat exchanger 5 side, and the control liquid flows as shown by the solid arrow 78, and circulates through the heat exchanger 5, the heater 7, and the regenerator 4.

Further, both the third switching valve 73 and the fourth switching valve 74 are switched to the heating device 3 side, and the heat source fluid circulates between the heat source device 1A and the heating device 3. During the defrosting and cooling operation as in the air conditioner shown in the first embodiment, the circulation of the control liquid and the heat source fluid, the operation of the temperature controller 60 as an evaporator, and the operation of the blowers 14 and 24 are performed. Is done.

The control liquid whose temperature has risen in the heater 7 releases moisture in the regenerator 4 to become a concentrated control liquid, which lowers in temperature in the heat exchanger 5 and further in temperature in the temperature controller 60. It falls and flows to the use side heat exchanger 26 of the indoor unit 2.
In the use-side heat exchanger 26, water vapor in the air flowing around is absorbed by the control liquid through the semipermeable membrane 30, and the air is cooled, and the dehumidified and cooled air is blown out into the room.

The control liquid that has absorbed water vapor from the surrounding air and cooled the air flowing around it to have a low concentration and a high temperature is supplied from the use side heat exchanger 26 to the control liquid pump 16 and the first switching. Flows to the heat exchanger 5 via the valve 61,
The heat exchanger 5 exchanges heat with the control liquid having a high temperature from the heater 7 to increase the temperature and flows to the heater 7. After that, similarly, the control liquid circulates between the indoor unit 1 and the outdoor unit 2, and the defrosting and cooling operation is performed.

Although the defrosting and cooling operation is performed as described above, for example, when the temperature of the indoor air is low and the temperature of the control liquid sent to the indoor unit 2 is desired to be high, the first control valve 66 is operated at the first temperature. By increasing the opening on the side of the bypass pipe 65 and decreasing the opening on the side of the temperature controller 60, the amount of the control solution flowing through the temperature controller 60 is reduced and the amount of the control solution bypassing the temperature controller 60 is reduced. The amount increases. Therefore, the temperature of the control liquid flowing into the indoor unit 2 rises, the temperature drop of the air in the use side heat exchanger 26 decreases, and the temperature of the air blown out from the indoor unit 2 rises.

Further, for example, when the dehumidifying capacity of the indoor unit 2 is decreased because the humidity of the indoor air has decreased, the opening degree of the second control valve 68 on the heater 7 side is decreased and the second bypass By increasing the opening on the side of the pipe 67,
As the amount of control liquid flowing through the heater 7 decreases, the amount of control liquid biasing the heater 7 increases. Therefore, the amount of water released from the control liquid in the regenerator 4 decreases, and the concentration of the control liquid flowing from the outdoor unit 1 to the indoor unit 2 decreases.

When the concentration of the control liquid flowing through the use side heat exchanger 26 decreases, the ability of the control liquid in the use side heat exchanger 26 to absorb water vapor from the air decreases, that is, the dehumidifying capacity decreases, and The humidity of the air blown from the unit 2 increases. In addition, the first control valve 66 and the second control valve 6
By simultaneously performing the control of 8 and increasing the temperature of the control liquid flowing to the indoor unit 2 and decreasing the concentration, both the cooling capacity and the dehumidifying capacity of the indoor unit 2 decrease.

When the fifth control valve 76 is adjusted to increase the amount of the heat source fluid flowing through the fifth bypass pipe 75, the amount of the control liquid flowing through the heating device 3 is decreased, and the amount of the control liquid flowing through the heating device 3 is reduced. The temperature rise of the control liquid is small. Then, when the temperature of the control liquid flowing through the regenerator 4 decreases, the amount of water released from the control liquid decreases, the concentration of the control liquid decreases, and the dehumidifying ability of the control liquid in the indoor unit 2 decreases.

Further, the first control valve 66 and the second control valve 6
When the eighth or fifth control valve 76 is adjusted in the opposite direction, the cooling capacity or dehumidifying capacity is improved, contrary to the case where the cooling capacity or dehumidifying capacity of the indoor unit 2 is reduced. The operation during the humidifying and heating operation will be described below. The discharge side of the first switching valve 61 is the absorber 44.
In addition to being switched to the side, the inflow side of the second switching valve 63 is switched to the absorber 44 side, and further, the third and fourth switching valves 73 and 74 are switched to the water heater 43 side.

Then, the control liquid is circulated by the operation of the control liquid pump 16 as shown by the broken line arrow in FIG. Further, the temperature controller 60 operates as a heater for the control liquid for heating the control liquid, for example, a high temperature refrigerant vapor flows from the high temperature generator. That is, the control solution circulates in the same manner as in the second embodiment, and the diluted control solution whose concentration is lowered by absorbing water in the absorber 44 flows to the temperature controller 60, and the control solution heated and raised in temperature is It flows to the indoor unit 2. Indoor unit 2
Then, the diluted control solution whose temperature has risen flows through the use side heat exchanger 26, and the water in the diluted control solution moves to the surface through the semipermeable membrane 30 and evaporates. Therefore, the sucked air is humidified and heated while flowing around the utilization side heat exchanger 26, and the air whose humidity and temperature have risen is discharged into the room.

The control liquid whose moisture has been released from the utilization side heat exchanger 26 to become thicker and which has radiated heat to lower the temperature is absorbed by the absorber 44.
Flow to the temperature controller 6
Flows to 0, is heated and rises in temperature, and then flows to the indoor unit 2. As described above, when the humidifying and heating operation is performed, for example, when the heating capacity of the indoor unit 2 is reduced, the opening degree of the first control valve 66 on the temperature controller 60 side is decreased and the first control valve 66 is opened. By increasing the opening degree on the bypass pipe 65 side, the amount of the control liquid flowing through the temperature controller 60 decreases, the heating amount decreases, and the temperature of the control liquid flowing into the indoor unit 2 decreases. Therefore, the air heating capacity of the use side heat exchanger 26 is lowered, and the temperature of the blown air is lowered.

Further, for example, when the humidity in the room rises and the humidifying capacity of the indoor unit 2 is lowered, the opening degree of the third control valve 70 on the absorber 44 side is decreased and the third control valve 70 is opened.
By increasing the opening degree of the bypass pipe 69 side of
The amount of the control liquid flowing through the absorber 44 decreases, the amount of water absorbed decreases, and the concentration of the control liquid flowing into the indoor unit 2 increases. For this reason, the humidification capacity of the use side heat exchanger 26 is reduced, and the humidity of the blown air is reduced.

Further, when the heating capacity and the humidifying capacity of the indoor unit 2 are reduced, the heating capacity and the humidifying capacity are reduced by performing the above-mentioned operation for lowering the heating capacity and the operation for lowering the humidifying capacity in parallel. Both the moisturizing capacity is reduced. In addition, when the heating capacity of the indoor unit 2 is improved, the first
By increasing the opening of the control valve 66 on the temperature controller 60 side and decreasing the opening on the first bypass pipe 65 side, the amount of the control liquid flowing through the temperature controller 60 increases and the heating amount increases. The temperature of the control liquid that increases and flows to the indoor unit 2 rises. Therefore, the air heating capacity of the use side heat exchanger 26 is increased, and the temperature of the blown air is increased.

When improving the humidifying capacity, the opening of the third control valve 70 on the absorber 44 side is increased and the opening on the third bypass pipe 69 side is decreased to reduce the absorption of the absorber 44. The amount of the control liquid flowing increases, the amount of absorbed water increases, and the concentration of the control liquid flowing to the indoor unit 2 decreases. Therefore, the humidification capacity of the use side heat exchanger 26 is improved, and the humidity of the blown air is improved.

Further, when the heating capacity and the humidifying capacity of the indoor unit 2 are improved, the heating capacity and the humidifying capacity are improved by performing the above-mentioned operation for improving the heating capacity and the operation for improving the humidifying capacity in parallel. Both the humidifying ability is improved. According to the above-described embodiment, during the dehumidifying and cooling operation, as in the case of the air conditioner of the first embodiment shown in FIG. 1, the concentrated control liquid having a low temperature flowing from the temperature controller 60 is used side heat exchange. It is possible to dehumidify the room air by cooling the room air while absorbing the water from the room air through the semipermeable membrane 30 and absorbing the water by the concentration adjusting liquid. As a result, it is possible to supply dehumidified air to the room without significantly reducing the temperature, and especially when the humidity is high and the temperature is relatively low, such as in the rainy season, the air that is dehumidified and the temperature is almost the same as the indoor unit It can be supplied from 2 to the room and keep the room comfortable.

As in the first embodiment, the control liquid flowing from the regenerator 4 to the heat exchanger 5 is the control liquid having a low temperature flowing from the outdoor unit 2 when flowing through the heat exchanger 5. Since it exchanges heat with and the temperature drops and is sent to the cooler 6,
The cooling capacity of the cooler 6 can be reduced, and the temperature of the control liquid flowing from the outdoor unit 2 is increased by the heat exchanger and sent to the heater 7. Therefore, the heating capacity of the heater 7 can be reduced. As a result, the operating efficiency of the air conditioner can be further improved.

During the humidifying and heating operation, the above second
In the same manner as in the embodiment described above, the diluted control liquid that absorbs water by the absorber 44 and is heated by the temperature controller 60 flows through the heat exchanger 26 on the utilization side, heats the room air, and heats the semipermeable membrane 30.
It is possible to replenish the room air with water and humidify it by the action of releasing water from the dilute control solution via the. As a result, the humidified air can be supplied to the room while increasing the temperature, and the air having the high temperature and the high humidity is supplied from the indoor unit 2 to the room, especially in the dry season when the temperature is low such as winter. Can be kept comfortable.

Further, the first, second, third and fourth switching valves 6
By switching 1, 63, 73, and 74, it is possible to easily switch between the dehumidifying and cooling operation and the humidifying and heating operation by one outdoor unit 1.
It is possible to operate in response to changes in humidity and temperature throughout the year. Further, the concentrated adjustment liquid or the rare adjustment liquid cooled or heated by the temperature controller 60 of the heat source device 1A is sent to the indoor unit 2, and the adjustment liquid dehumidifies the indoor air or humidifies the indoor air. Since cooling or heating is performed by the control liquid flowing through the use side heat exchanger 26, the control liquid can be used for both humidity control and temperature control, and piping between the outdoor unit 1 and the indoor unit 2 can be used. Can be simplified, and the installation work can be simplified.

Further, since the waste heat of the cooling water or the exhaust gas from the heat source unit 1A is used as the heating source of the heating device 3 and the water heater 43, the operation efficiency can be improved and the air conditioner It is possible to slightly reduce the operating cost. Further, the semipermeable membrane 12 is used for separating water from the adjusted liquid in the regenerator 4 in which the outside air flows around, and the closed high temperature chamber 41 is provided with the absorber 44 constituted by the semipermeable membrane 47.
Moreover, since the semipermeable membrane 30 is used for the use-side heat exchanger 26 through which the indoor air flows around, it is possible to avoid direct contact of the control liquid circulating between the outdoor unit 1 and the indoor unit 2 with the air. In addition, it is possible to avoid mixing impurities such as dust into the control liquid, to use the control liquid for a long period of time, and to avoid a decrease in the control liquid circulation amount or blockage of the control liquid circulation path due to impurities. Maintenance management can be simplified.

The present invention is not limited to the above-mentioned embodiments, and various implementations are possible without departing from the gist of the present invention. For example, in the embodiment of the air conditioner shown in FIGS. 1 to 3, the heat source unit 1A is, for example, an absorption refrigerator, but the heat source unit 1A is, for example, an engine driven air conditioner. Also, when the heat of the exhaust gas from the engine and the heat of the cooling water are used as the heat source of the heating device 3 or the water heater 43, the same effect can be obtained.

In the embodiment of the air conditioner shown in FIGS. 1 to 3, the outdoor unit 1 and one indoor unit 2 are connected by piping, but a plurality of indoor units 2 are connected. When the pipes are connected, the indoor unit 2 can keep the room comfortable, and the operating efficiency of each indoor unit can be improved to further reduce the operating cost of the air conditioner.

Further, the indoor unit 2 may be installed indoors or may be embedded in the ceiling or the like.
