Japanese Patent No. 2933265

  In the prior art air conditioner disclosed in the above-mentioned Patent Document 1, no matter what temperature or humidity of the outside air is supplied to the heating means, the outside air humidity is in a state suitable for regeneration of the dehumidifying means. In the heating means, the outside air is always heated constantly and supplied to the dehumidifying means. Therefore, in the conventional air conditioner, when the dehumidifying means is regenerated, the outside air may be heated to a higher temperature than necessary by the heating means, and energy loss has been generated accordingly.

  Further, as described above, when the outside air is heated to a high temperature in preparation for the case where the outside air is high in humidity, the outside air whose humidity is excessively low is supplied to the dehumidifying means for regeneration. Dehumidification capacity becomes excessive. On the contrary, if the heating setting temperature of the outside air in the heating means is set low in order to prevent the dehumidifying capability of the dehumidifying means after regeneration from becoming excessively high, when the outside air with high humidity is introduced. The dehumidifying means cannot be fully regenerated. Therefore, if the outside air is heated to a constant temperature and supplied to the dehumidifying means for regeneration without considering the humidity of the outside air, the dehumidifying ability of the dehumidifying means becomes unstable.

  Therefore, the present invention includes an air conditioner capable of minimizing energy loss accompanying heating of the gas supplied for regeneration of the dehumidifying means and exhibiting stable dehumidifying ability after regeneration, and the air conditioner. The purpose was to provide environmental testing equipment.

  The air conditioner of the present invention provided to solve the above-described problem is for heating regeneration while adsorbing and dehumidifying moisture contained in the gas by passing the gas to be processed. The dehumidifying means capable of releasing the adsorbed moisture by allowing the gas to pass therethrough and regenerating the moisture absorption capacity, and heating the gas supplied from the outside to a predetermined set temperature to obtain the dehumidifying gas as a regeneration gas A heating means that can be supplied to the heating means, and an outside air state detection means that can detect either or both of the temperature and humidity of the gas supplied to the heating means from the outside, and is supplied to the dehumidifying means The regeneration gas is set to a higher temperature when the detection temperature or detection humidity of the outside air state detection means is higher than when the detection temperature or detection humidity is low. It is set to (claim 1).

  The air conditioner of the present invention detects the temperature and humidity of the gas supplied from the outside to the heating means by the outside air state detection means. Here, generally, the gas such as outside air supplied to the heating means tends to have high humidity when it is high temperature and low when it is low temperature. Therefore, when the gas supplied to the heating means is high temperature, the regeneration capacity of the dehumidifying means is low due to the high humidity, and if the gas is not heated to high temperature by the heating means and supplied to the dehumidifying means, the adsorbed moisture is sufficient There is a possibility that it cannot be released. On the other hand, when the gas supplied to the heating means from the outside is low in temperature, the humidity is low, so the moisture adsorbed by the dehumidifying means can be reduced without being heated to a high temperature by the heating means and supplied to the dehumidifying means. It can be released sufficiently. Therefore, when the gas supplied to the heating means from the outside is at a low temperature, if the gas is heated to the same temperature as that at the high temperature, an energy loss is generated accordingly.

  If the gas is heated under the same conditions and supplied to the dehumidifying means regardless of the temperature and humidity of the gas supplied to the heating means from the outside, the humidity of the gas supplied for regeneration becomes non-uniform and regeneration is performed. Variations occur in the dehumidifying ability of the dehumidifying means later. Specifically, when the heating means is heated under the same conditions as when the temperature and humidity of the gas are high even though the temperature and humidity of the gas supplied from the outside to the heating means are low, the dehumidification means is used for regeneration. There is a possibility that the humidity of the supplied gas is excessively low and the dehumidifying capacity of the dehumidifying means after the regeneration becomes excessively high. On the other hand, if the heating means is heated under the same conditions as when the temperature or humidity of the gas is low even though the temperature or humidity of the gas supplied to the heating means from the outside is high, As a result, there is a possibility that the dehumidifying ability of the dehumidifying means cannot be sufficiently recovered.

  Therefore, based on such knowledge, the air conditioner of the present invention is provided with an outside air state detection means, and the set temperature of the gas for regeneration when the detected temperature and detected humidity are high is detected by the detected temperature and detected humidity. It is supposed to be higher than the set temperature when the temperature is low. Therefore, in the air conditioner of the present invention, the energy loss when the regeneration gas is heated by the heating means can be minimized.

  Further, with the configuration described above, the humidity of the gas supplied to the dehumidifying means for regeneration after being heated by the heating means can be stabilized. Therefore, according to this invention, it can prevent that the dehumidification capability of the dehumidification means after reproduction | regeneration becomes unstable.

  In the air conditioner of the present invention, the dehumidifying means has a dehumidifying rotor through which gas can pass and can adsorb and release moisture, and the dehumidifying rotor includes a processing side region in which the gas to be processed flows, It may be rotatable so as to pass through the regeneration side region through which the gas flows.

  According to such a configuration, it is possible to continuously perform dehumidification of the gas to be processed by the dehumidifying means and regeneration of the dehumidifying means, and prevent deterioration of the dehumidifying ability of the dehumidifying means over time.

  An environmental test apparatus according to the present invention has the air conditioner according to claim 1 or 2 and an air conditioned space, and is capable of supplying gas that has passed through a dehumidifying means of the air conditioner to the air conditioned space. (Claim 3).

  Since the environmental test apparatus of the present invention includes the above-described air conditioner, there is little energy loss in the heating means. Moreover, when it is set as the above-mentioned structure, after heating with a heating means in an air conditioner, the humidity of the gas supplied to a dehumidification means for reproduction | regeneration can be stabilized. Therefore, according to this invention, the dehumidification capability in an air conditioner is stable, and the humidity in an air-conditioned space can be stabilized.

  According to the present invention, an air conditioner capable of minimizing energy loss accompanying heating of a gas supplied for regeneration of the dehumidifying means and exhibiting a stable dehumidifying ability after regeneration, and the air conditioner are provided. Environmental test equipment can be provided.

  Next, the air conditioner 10 and the environmental test apparatus 100 according to an embodiment of the present invention will be described in detail with reference to the drawings. As shown in FIG. 1, the environmental test apparatus 100 (hereinafter also referred to as the test apparatus 100) includes an air conditioner 10, an air conditioned space 50, and a circulation channel 60. The air conditioner 10 is configured by a so-called desiccant type dehumidifier. As shown in FIGS. 1 and 2, the air conditioner 10 includes a dehumidification rotor 12 (dehumidification means), a heating means 14, an outside air temperature detection means 16 (outside air state detection means), an air supply temperature sensor 18, and a blower 20. ing.

  The dehumidifying rotor 12 has a disk-like appearance, and is constituted by, for example, a roll of a laminate of plate-shaped material paper and corrugated material paper. The dehumidifying rotor 12 has a honeycomb shape, and gas can pass through in the thickness direction. The dehumidifying rotor 12 carries a moisture absorbent such as silica gel, and moisture contained in the gas passing through the dehumidifying rotor 12 can be adsorbed and dehumidified by the dehumidifying agent. Further, the dehumidification rotor 12 can regenerate the moisture absorption capability by allowing the heated regeneration gas to pass through to release the moisture adsorbed by the moisture absorbent as described above.

  The dehumidifying rotor 12 is housed in a casing (not shown) constituting the air conditioner 10, and is rotated at a predetermined speed by receiving power from a power source such as a motor (not shown). Yes. As shown in FIG. 2, the space in the casing (not shown) in which the dehumidification rotor 12 is accommodated is divided into a processing side region 32 and a regeneration side region 34 by a partition 30. As indicated by an arrow in FIG. 2, when the dehumidifying rotor 12 rotates, the processing side region 32 and the regeneration side region 34 are alternately passed.

  The process side area | region 32 is an area | region through which the air (gas) of dehumidification object flows. A circulation channel 60 is connected to the processing side region 32, and a blower 62 is provided in the middle of the circulation channel 60. Therefore, air can be circulated between the dehumidification rotor 12 and the air-conditioned space 50 by operating the blower 62.

  The regeneration side region 34 is a region through which air (gas) for regenerating the moisture absorption capability of the dehumidifying rotor 12 flows. An outdoor air introduction path 36 for introducing the regeneration air into the regeneration side region 34 is provided upstream in the flow direction of air for regenerating the moisture absorption capacity with respect to the regeneration side region 34 (hereinafter also referred to as regeneration air). Is provided. An exhaust passage 38 for exhausting the regeneration air that has passed through the dehumidification rotor 12 is provided downstream of the regeneration region 34 in the flow direction of the regeneration air.

  In the middle of the outside air introduction path 36, the heating means 14, the outside air temperature detection means 16, the supply air temperature sensor 18, and the blower 20 described above are provided. By operating the heating means 14 and the blower 20, the outside is provided from the outside. The taken-in air (outside air) can be heated and introduced as regeneration air into the regeneration-side region 34 described above. The heating means 14 is constituted by a conventionally known electric heater or the like. The output of the heating means 14 is based on the temperature detected by the supply air temperature sensor 18 provided on the downstream side in the flow direction of the regeneration air flowing through the outside air introduction path 36, and the temperature of the air fed into the regeneration side region 34 is the set temperature. Feedback control is performed so as to be T.

  The set temperature T of the regenerating air supplied after being heated by the heating means 14 is a detected temperature (hereinafter referred to as an outside temperature) of the outside air temperature detecting means 16 provided upstream of the heating means 14 and the blower 20 in the air flow direction. (Also referred to as temperature t). Specifically, the set temperature T when the outside air temperature t is high is set to be higher than the set temperature T when the outside air temperature t is low. In the air conditioner 10 and the test apparatus 100 of this embodiment, when the outside air temperature t is higher than the predetermined threshold temperature A (t> A), the set temperature T is set to 140 ° C., and the outside air temperature t is the threshold temperature A. In the following (t ≦ A), the set temperature T is set to 100 ° C.

  Since the test apparatus 100 includes the air conditioner 10 described above, the humidity in the air-conditioned space 50 can be adjusted by operating the air conditioner 10. Specifically, when the humidity in the air-conditioned space 50 is adjusted, the dehumidification rotor 12 receives power from a power source (not shown) such as a motor and rotates. As a result, the dehumidification rotor 12 rotates so as to alternately pass through the processing side region 32 and the regeneration side region 34 divided by the partition 30. Further, when the humidity of the air-conditioned space 50 is adjusted, the blower 62 provided in the circulation flow path 60, the blower 20 provided in the outside air introduction path 36, and the heating means 14 are operated.

  When the air blower 62 is activated, a circulating flow is generated in which the air taken out from the air-conditioned space 50 passes through the processing side region 32 and returns to the air-conditioned space 50. At this time, the air circulating through the circulation channel 60 passes through the dehumidification rotor 12. Thereby, the moisture contained in the air taken out from the air-conditioned space 50 is absorbed by the moisture absorbent carried on the dehumidification rotor 12 and is dehumidified. The dehumidified air is returned to the conditioned space 50 via the circulation flow path 60. As a result, the air-conditioned space 50 is dehumidified.

  On the other hand, when the blower 20 operates, outside air is taken into the outside air introduction path 36. The outside air taken into the outside air introduction path 36 is heated by the heating means 14 to the set temperature T set as described above based on the outside air temperature t detected by the outside air temperature detecting means 16 and is used as regeneration air. The reproduction side area 34 is supplied. That is, the outside air is heated to 140 ° C. when the outside air temperature t is higher than the threshold temperature A, and is heated to 100 ° C. when the outside air temperature t is equal to or lower than the threshold temperature A. 34.

  When the outside air heated by the heating means 14 is supplied to the regeneration side region 34, it is supplied to a portion passing through the regeneration side region 34 in the dehumidification rotor 12. Thereby, the water | moisture content absorbed by the hygroscopic agent carry | supported by the dehumidification rotor 12 is discharge | released, and the dehumidification rotor 12 will be in the reproduced | regenerated state. The moisture released from the dehumidification rotor 12 is discharged together with the air (outside air) that has passed through the dehumidification rotor 12 through the exhaust path 38.

  The air conditioner 10 described above detects the temperature of the outside air (outside temperature t) supplied to the heating unit 14 via the outside air introduction path 36 by the outside temperature detecting unit 16, and whether the outside temperature t is higher than the threshold temperature A. The set temperature T of the outside air supplied for regeneration to the dehumidification rotor 12 is adjusted depending on whether or not. Therefore, in the air conditioner 10, when the outside air temperature t is low and the amount of moisture contained in the outside air is small, the outside air can be supplied to the dehumidifying rotor 12 without excessively heating. Therefore, according to the air conditioner 10 and the test apparatus 100 described above, the energy loss in the heating means 14 can be suppressed to the minimum.

  Further, if the set temperature T is adjusted by assuming the amount of water contained in the outside air taken into the outside air introduction path 36 based on the level of the outside temperature t as described above, the regeneration is performed on the dehumidifying rotor 12. The humidity of the regeneration air supplied for use can be stabilized. Therefore, in the above-described air conditioner 10, the dehumidifying capacity of the dehumidifying rotor 12 after regeneration is stable. Moreover, according to the test apparatus 100 described above, the humidity of the air-conditioned space 50 can be stabilized.

  In the present embodiment, the dehumidification rotor 12 is a target of dehumidification processing, and a processing side region 32 in which air circulating through the circulation channel 60 flows, and a regeneration side region 34 in which air (outside air) heated by the heating means 14 flows. It is set as the structure rotated so that it may pass. Therefore, in the above-described air conditioner 10, the dehumidification rotor 12 can continuously perform dehumidification of the air and the regeneration of the dehumidification rotor 12, and the dehumidification capability of the dehumidification rotor 12 can be prevented from deteriorating with time.

  In the above-described embodiment, an example in which the set temperature T is switched between two stages of 100 ° C. and 140 ° C. depending on whether or not the outside air temperature t detected by the outside air temperature detecting unit 16 is high with respect to the predetermined threshold temperature A is exemplified. The present invention is not limited to this, and further, the threshold temperature A is provided in multiple stages, and the outside air is heated by the heating means 14 to be supplied to the dehumidifying rotor 12 so that the set temperature T is set according to the threshold temperature A. It is good. The set temperature T is not limited to the above-described 100 ° C. and 140 ° C., and can be appropriately set so that the air supplied for regeneration has a humidity suitable for the regeneration of the dehumidifying rotor 12.

  The set temperature T does not necessarily have to be set stepwise according to the outside air temperature t, but is a mathematical formula set based on the relationship between the outside air temperature t and the amount of moisture contained in the outside air. Alternatively, the set temperature T may be set based on the correlation, and the output of the heating unit 14 may be adjusted based on the set temperature T. Even in such a configuration, the dehumidification rotor 12 can be regenerated by supplying air heated to the regeneration side region 34 in a state suitable for regeneration as in the above embodiment.

  In the above embodiment, the configuration in which the set temperature T is set based on the outside air temperature t detected by the outside air temperature detecting means 16 is exemplified, but the present invention is not limited to this. More specifically, instead of the outside air temperature detecting means 16, an outside air humidity detecting means 22 (outside air state detecting means) capable of detecting the humidity of the outside air taken from outside for regeneration is provided upstream of the heating means 14. It is good also as a structure. In the case of such a configuration, when the humidity detected by the outside air humidity detection means 22 is high, it is set as compared with the case where the humidity is low (corresponding to the case where the outside temperature t is low) as in the case where the outside temperature t is high. By setting the temperature T high, the energy loss in the heating means 14 can be suppressed and the dehumidifying capacity of the dehumidifying rotor 12 can be stabilized as in the case of the above-described embodiment.

  As described above, in the case where the outside air humidity detection means 22 is provided, as in the case where the set temperature T is adjusted based on the outside air temperature t, the humidity w of the taken outside air is higher than the predetermined threshold humidity B. The set temperature T may be set to a high temperature, and the set temperature T may be set to a low temperature when the humidity w is equal to or lower than the threshold humidity B. Alternatively, the threshold humidity B may be set in a plurality of stages, and the set temperature T may be set for each stage. Furthermore, the set temperature T may be set as a function in relation to the humidity w, and the output of the heating means 14 may be adjusted based on this result.

  The air conditioner 10 is configured to include both the outside air temperature detection unit 16 and the outside air humidity detection unit 22 described above, and sets the set temperature T using both the outside air temperature t and the humidity w detected by these. It is good to do. Specifically, the set temperature T when the outside air temperature t and the humidity w are high may be set to a higher temperature than when the outside air temperature t and the humidity w are low. According to such a configuration, the level of the set temperature T can be adjusted with higher accuracy, energy loss in the heating unit 14 can be minimized, and the dehumidifying ability of the dehumidifying rotor 12 can be stabilized.

  In the said embodiment, the example which employ | adopted the dehumidification rotor 12 which rotates so that it may alternately pass the process side area | region 32 and the reproduction | regeneration side area | region 34 as a dehumidification means for dehumidifying the air which circulates through the circulation flow path 60 was illustrated. However, the present invention is not limited to this, and other types of dehumidifying means that can be dehumidified and regenerated by ventilation instead of the dehumidifying rotor 12 may be adopted.

  In the above embodiment, the configuration in which both the gas to be dehumidified and the gas heated by the heating means 14 for regeneration of the dehumidification rotor 12 (regeneration gas) is air is exemplified. It is not limited to, and any one gas may be other than air.

  In the said embodiment, although the example which provided the outside temperature detection means 16 and the outside air humidity detection means 22 in the apparatus of the air conditioner 10 was illustrated, this invention is not limited to this, The outside temperature detection means 16 or The outside air humidity detection means 22 may be provided outside the apparatus. Moreover, the air-conditioned space 50 shown in the above embodiment may include an air-conditioning device such as a heater, a cooler, and a humidifier.
