As a result, it is possible to precisely control the supply air temperature and humidity. And a comfortable indoor space can be provided.

(Embodiment 10) FIG. 10 shows a tenth embodiment of the present invention.

As in the previous embodiment, the same air passage configuration and parts as those in the first embodiment are denoted by the same reference numerals.
The detailed description is omitted.

In FIG. 10, there is provided a hot and cold heat generating device 26 using a Peltier element capable of separating a heating portion and a cooling portion.
The first air supply ventilation passage 10a passes through the total heat exchanger 2, the dehumidifying rotor 3, and the first cooling / heating section 28a from the outdoor-side suction port 8, and communicates with the first indoor-side discharge port 9a. Exhaust air passage 14
a passes through the first indoor-side suction port 12a, the heat generating portion 27, and the dehumidifying rotor 3, communicates with the first outdoor-side discharge port 13a, and the second exhaust ventilation passage 14b connects with the second indoor-side suction port.

Further, by controlling the current flowing through the cooling / heating device 26, the amount of heat in the cooling portion and the heating portion can be precisely controlled. As a result, the supply air temperature and humidity can be controlled with high accuracy. And a comfortable indoor space can be provided.

(Embodiment 11) FIG. 11 shows an eleventh embodiment of the present invention.

As in the previous embodiment, the same air passage configuration and parts as those in the first embodiment are denoted by the same reference numerals.
The detailed description is omitted.

In FIG. 11, a cooling / heating heat generating apparatus 2 using a Peltier element is provided in a flow path passing through a second bypass air path 22b which does not pass through the dehumidifying rotor 3 as a first air supply ventilation path.
6 and the first exhaust air path switching damper 17a is switched, and the third exhaust air path 1
4c, and has a heat generating portion 27 in the air path.

In the above configuration, the cooling operation is performed in a normal operation, but the first and third supply air passage switching dampers 23a and 23c and the first exhaust air passage switching damper 17a are operated during heating in winter. At the same time, by switching the polarity of the Peltier element corresponding to the heat generating section 27 and the first cold / hot section 28a, the first cold / hot section 28a becomes the heat generating section and the heat generating section 27 becomes the cold section, so that the total heat exchange is performed. The air supply after passing through the vessel 2 is further heated to perform heating.

Therefore, cooling and heating while ventilating throughout the year can be obtained with a more compact desiccant air conditioner.

Further, by controlling the current flowing through the cooling / heating device 26, the calorific value of the heat generating portion can be precisely controlled. As a result, the supply air temperature can be controlled with high accuracy, and the comfort can be improved. It is possible to provide a comfortable indoor space.

(Embodiment 12) The amount of air supplied during cooling is equal to or greater than the sum of the amount of exhaust air.

The sum of the exhaust air volumes is the same as in Examples 1, 2 and 5.
And the second exhaust airflow passing through the total heat exchanger 2 or the fourth sensible heat exchanger 5d in the second exhaust air passage 14b and the second exhaust airflow passing through the dehumidifying rotor 3 in the first exhaust air passage 14a. 1
In the third embodiment, the second exhaust air flow passing through the total heat exchanger 2 in the second exhaust air passage 14b and the third exhaust air passing through the third exhaust air passage 14c. In the fourth embodiment, this is the sum of the second exhaust airflow passing through the total heat exchanger 2 in the second exhaust airflow passage 14b, the third exhaust airflow, and the fourth exhaust airflow passage 14d. This is the sum with the fourth exhaust air volume. In this case, by setting the supply air flow rate to be always large, the inside of the room is prevented from being negative pressure, and the inflow of outside air is prevented.

Further, the second exhaust air volume is set larger than the other exhaust air volumes, and the amount of exhaust air passing through the dehumidifying rotor 3 is reduced to about １ ／ of the supplied air volume, so that the moisture adsorption by the dehumidifying rotor 3 is improved. Can be done As a result, the air conditioning load of the desiccant air conditioner 1 can be reduced.

(Thirteenth Embodiment) As in the twelfth embodiment, the air supply air volume is set to be equal to or greater than the sum of the exhaust air volumes even during heating. This prevents the inside of the room from becoming negative pressure, prevents outside air from entering, reduces the air-conditioning load, and also enables efficient heat exchange in the total heat exchanger 2. As a result, the air conditioning load of the desiccant air conditioner can be reduced.

(Embodiment 14) At least a part of the electricity supplied to the desiccant air-conditioning system is operated using electricity from a generator that generates electricity using fuel such as gas or oil. These power generations have higher power generation efficiency than power supply using a normal commercial power supply because there is no power transmission loss.

That is, the primary energy consumption is small, and as a result, the carbon dioxide emission is also small. Therefore, by using the electricity obtained by these power generations, it is possible to perform air-conditioning that is energy-saving and friendly to the global environment.

(Embodiment 15) At least a part of the electricity supplied to the desiccant air-conditioning system is operated using electricity generated from the fuel cell, particularly from the polymer electrolyte fuel cell. This power generation has a higher power generation efficiency as compared to the case of using a normal commercial power supply as in the fourteenth embodiment, because there is no power transmission loss.

That is, the primary energy consumption is small, and as a result, the carbon dioxide emission is also small. In particular, in the case of a fuel cell, especially a solid polymer type, there is no emission from the main body, and only a small amount is emitted when a reformer that generates hydrogen from city gas or the like is used, and the influence of global warming is small. Therefore, by using the electricity obtained by this power generation, it is possible to perform air-conditioning that is energy-saving and that is friendly to the global environment and less affected by global warming.

(Embodiment 16) A so-called cogeneration system in which the heating / regenerating means 4 and the heating means 24 of the desiccant air-conditioning system generate power using fuel such as gas or oil instead of electricity such as an electric heater, or a gas engine heat pump And so on. These heats have a temperature of about 80 ° C. to 120 ° C. and are used for hot water supply. In summer, however, heat used is not particularly used and is discarded as waste heat.

Also, in the conventional desiccant type dehumidification and cooling, electric heaters and the like are often used for regeneration, so that more energy is required than in a refrigeration cycle type cooling or dehumidifier using a refrigerant, and thus it has been widely used. Did not.

For this reason, since waste heat originally discarded is used as renewable energy and heating means, the inputs are a blower, a motor for a dehumidifying rotor, and a water supply pump. If it is used, it will be more effective as an energy-saving air conditioner that is more environmentally friendly and does not use Freon.

In addition, an electric heater or a heat source such as a Peltier element may be used in combination with the above-described exhaust heat.
There is no difference in the effects.

(Embodiment 17) Similarly, the heat regenerating means 4 and the heating means 24 of the desiccant air-conditioning system are provided with exhaust heat from the main body generated during power generation of the fuel cell, particularly of the polymer electrolyte type, and hydrogen for generating hydrogen. Either or both of the exhaust heat from the reformer is used.

The operating temperature of a polymer electrolyte fuel cell is 80 ° C. to 100 ° C., which is near normal temperature, compared with other fuel cells, and the waste heat is used for reheating means and heating means. Cooling and heating by desiccant air-conditioning while generating electricity can be performed with energy saving while performing ventilation.

When the temperature of the exhaust heat from the polymer electrolyte fuel cell is about 80 ° C., regeneration by the dehumidifying rotor may not be performed sufficiently. In recent years, the performance of the dehumidifying rotor has been improved, and cooling can be sufficiently performed even at a performance of about 80 ° C., but a higher regeneration temperature is required to obtain further performance.
In a fuel cell such as a polymer electrolyte fuel cell, hydrogen is generated from city gas or the like using a reformer.

Most of the reformers used here generate high-temperature exhaust heat from catalytic reactions and the like. Of course, the waste heat is used in the reformer itself and the fuel cell system.
Waste heat exceeding ℃ is generated.

By utilizing this for reheating means and heating means, cooling and heating in desiccant air-conditioning while generating power in the fuel cell can be further improved while performing ventilation and energy-saving. I can do it.

In recent years, from the viewpoint of reducing carbon dioxide and harmful substances, an electric vehicle using a polymer electrolyte fuel cell as a power source for a vehicle has attracted attention. The exhaust heat from the reformer can be used as a heating and regenerating unit and a heating unit of the desiccant air conditioning system, and used as an air conditioner for a vehicle.

It is to be noted that an electric heater or a heat source such as a Peltier element may be used in combination with the exhaust heat as described above.
There is no difference in the effects.

(Embodiment 18) Exhaust heat from an absorption-type air conditioner is used for the heating / regenerating means 4 and the heating means 24 of the desiccant air conditioning system. Absorption type air conditioners (refrigerators) are also attracting attention as non-fluorocarbons in recent years, and generate relatively high-temperature exhaust heat (120 ° C.) generated when power is generated using gas or oil or power generated by a fuel cell. Above), and is used as a so-called cogeneration system, but exhaust heat is also generated from the absorption type cooling machine.

By utilizing this in the same manner as in Examples 16 and 17, it is possible to operate not only the absorption-type cooling device but also the desiccant cooling device. In particular, the absorption temperature is 120 ° C or higher for desiccant, but lower than 1 ° C for desiccant.
Since the temperature is about 20 to 80 ° C., heat cascade can be used, and energy-saving air conditioning can be performed as a total system.

(Embodiment 19) At least a part of the supply-side cooler 6, the exhaust-side cooler 7, and the humidifying means 25 is in direct contact with water and utilizes the latent heat of evaporation of water. This is achieved by spraying water in fine particles, evaporating water from non-woven fabric, etc., and using ultrasonic waves. By cooling, energy-saving air conditioning can be performed.

Further, since a cooling system using a refrigerant such as chlorofluorocarbon is not used for the cooler, an air-conditioning system that is friendly to the global environment can be provided.

(Example 20) At least a part of the water used for the supply-side cooler 6, the exhaust-side cooler 7, and the humidifying means 25 is a fuel cell, especially a polymer electrolyte type fuel cell, and is generated from the cell body or the like. Utilize the water that is produced. Since the fuel cell originally performs the reverse process of electrolysis of water, water is naturally produced.

[0131] Water is also generated on the reformer side. Most of these waters are used to protect the membrane of the cell body.However, the water discharged afterwards is cooled once and used for coolers and humidifying means to provide a total fuel cell and desiccant system. The system can be operated without waste.

Further, since the generated water is clean water having relatively few impurities, the possibility of causing troubles such as dirt and clogging of the water spray mechanism and the humidifying mechanism is reduced, and a highly reliable system is provided. Can be obtained.

(Example 21) As cooling of a target space, cooling by a desiccant air-conditioning system and cooling operation by a heat pump type air conditioner using electricity from a generator that generates electricity using fuel such as gas or oil. Air conditioning.

This is because power generation using fuel such as gas or petroleum is more efficient than a commercial power supply due to the power transmission loss, operates a highly efficient heat pump type air conditioner, and further discharges heat to the desiccant air conditioner. By using the system, energy saving and comfortable air conditioning can be performed as a total system.

(Example 22) Similarly, cooling of a target space is performed by cooling with a desiccant air-conditioning system and cooling operation with a heat pump type air conditioner using electricity obtained from a fuel cell such as a polymer electrolyte fuel cell. Perform air conditioning.

This is because power generation using a fuel cell of a solid polymer type or the like is more efficient than a commercial power supply due to the power transmission loss, and a high efficiency heat pump air conditioner is operated by the power generation. By using the system, energy-saving and comfortable air conditioning can be performed as a total system.

Although a schematic diagram of a cross-flow type is shown as a total heat exchanger in Examples 1 to 22, a stationary counter flow or a rotary heat exchanger may be used as the total heat exchanger. No difference in effect.

Similarly, the first, second, third, and fourth sensible heat exchangers may be any of a rotary type, a stationary type, and a heat pipe, so that there is no difference in operation and effect.

The position of the air supply and the plurality of exhaust blowers is not limited to the position shown in the drawing, but may be anywhere in each flow path as long as the function is satisfied.
