この発明は環境試験機器等に使用される恒温恒
湿器の温湿度調節方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for controlling temperature and humidity of a constant temperature and humidity chamber used for environmental testing equipment and the like.
恒温恒湿器の調温調湿室内の通風径路に送風
機、加熱器、除湿器および加湿器をチヤンバ内空
気の循環方向とは逆方向に配置する構成は効果的
な空気調和を行う配列として知られている。 A configuration in which a blower, a heater, a dehumidifier, and a humidifier are placed in the ventilation path in the temperature and humidity control chamber of a constant temperature and humidity chamber in the opposite direction to the circulation direction of the air inside the chamber is known as an arrangement for effective air conditioning. It is being
即ち、従来構成において、加湿器は調温調湿室

と、該加湿パン中に貯溜された（水深の浅い）一
定水位の加湿用水と、該水中に設けられたシーズ
ヒーターとからなるので、水蒸気発生面積が広く
設定され水蒸気発生量が増えると共に水蒸気発生
速度も速まり加湿能力をたかめている。 That is, in the conventional configuration, the humidifier has a flat humidifying pan formed over almost the entire bottom wall surface of the temperature and humidity control room, and a constant level of humidifying water (shallow water) stored in the humidifying pan. , and a sheathed heater installed in the water, the water vapor generation area is set wide, the amount of water vapor generated increases, and the speed of water vapor generation increases, increasing the humidifying ability.

通電により加湿調節を行い温湿度制御を良くして
いる。これは、加湿後に除湿するので飽和速度を
遅らせ余分な水蒸気の循環を抑えるので急激な加
湿が行われないためである。 In addition, this temperature and humidity control is achieved by constantly circulating refrigerant at a constant rate in a dehumidifier with a large heat capacity, and by continuously driving a dehumidifier with a small heat capacity. The PID temperature controller compares and calculates the dry bulb temperature detected by the early temperature sensor and the set dry bulb temperature sent from the controller, and sends the resulting output signal to the SSR unit. Similarly, humidifiers with a small heat capacity adjust the heating by continuously controlling energization to the dry bulb temperature detected by a fast-responsive temperature sensor and the set wet bulb temperature sent from the controller. The PID temperature controller performs comparison calculations and sends the resulting output signal to the SSR unit.
Humidification is controlled by continuously controlling electricity from the SSR unit to the humidifier to improve temperature and humidity control. This is because dehumidification is performed after humidification, which slows down the saturation rate and suppresses circulation of excess water vapor, preventing rapid humidification.
しかしながら、この従来の方法では、加湿器に
より加湿された空気が除湿器の除湿作用を全て受
けるので、加湿器は設定湿度まで加湿するのに得
ようとすする加湿雰囲気以上に循環空気を加湿す
る必要があり、結果として加湿器の加湿能力が損
なわれる。 However, in this conventional method, the air humidified by the humidifier receives all the dehumidifying action of the dehumidifier, so the humidifier humidifies the circulating air more than the humidified atmosphere that it is trying to achieve to humidify the set humidity. as a result, the humidification capacity of the humidifier is impaired.
また、除湿器は常時駆動するので循環空気中の
水蒸気が結露しているが、特に、高湿雰囲気を得
ようとする場合には循環空気も高湿となり除湿作
用が増えるので、送風作用や除湿作用の障碍とな
る。 In addition, since dehumidifiers are constantly driven, the water vapor in the circulating air condenses, but especially when trying to create a high-humidity atmosphere, the circulating air also becomes highly humid and the dehumidifying effect increases, so the blowing effect and dehumidifying effect increase. It becomes an obstacle to the action.
従つて、加湿器や送風機は能力乃至容量の大き
いものを使用する必要があり、機器の大型化は避
けられず、エネルギー消費が多く欠点がある。 Therefore, it is necessary to use a humidifier or blower with a large capacity or capacity, which inevitably increases the size of the equipment and consumes a lot of energy, which is disadvantageous.

湿器の温湿度調節方法を提供するにある。 This invention was newly created as a result of intensive research to solve the above problems all at once, and its purpose is to satisfy all the advantages of the conventional temperature and humidity control method of a constant temperature and humidity chamber. At the same time, it improves the efficiency of heat exchange and saves energy. It also makes it easier to make minute temperature and humidity adjustments during the steady state of the temperature and humidity chamber, improving temperature and humidity control, and improves responsiveness and temperature and humidity during unsteady times (humidifying). An object of the present invention is to provide a method for controlling temperature and humidity in a constant temperature and humidity chamber that improves control.

The purpose is to provide a method for controlling temperature and humidity.

ことを要旨とする。 The temperature and humidity control method for a constant temperature and humidity chamber according to the present invention includes dividing circulating air that flows in from a suction port and passing through a dehumidifier into two parts, humidifying one side of the circulating air with a humidifier, and then further humidifying at least part of the air. The main idea is to pass the circulating air through one part of the dehumidifier, to pass the other part of the circulating air through the other part of the dehumidifier directly from the suction port without humidifying it, and to merge the two and discharge it from the ventilation port.
以下、この発明に係る恒温恒湿器の温湿度調節
方法の好適実施例を図面に基づいて説明する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a method for controlling temperature and humidity in a constant temperature and humidity chamber according to the present invention will be described below with reference to the drawings.

されている。 The chamber body 1 of the constant temperature and humidity chamber shown in Fig.
The temperature and humidity control room 3 is divided into a test chamber 2 and a temperature and humidity control room 3. In the meantime, a blower 4 for circulating and stirring the air inside the chamber, a heater 5, a dehumidifier 7, and a humidifier 9 are arranged in this order.

いる。 Next, to control the temperature and humidity of the circulating air E, a dehumidifier 7 with a large heat capacity is operated continuously by constantly circulating a refrigerant at a substantially constant rate, and a heater 5 with a small heat capacity is installed in the test chamber near the air outlet. The dry bulb temperature detected by the fast-responsive temperature sensor S1 and the set dry bulb temperature sent from the controller C1 are
Temperature controller C2 performs comparison calculations and sends the resulting output signal to SSR unit C3, which
Heating is controlled by continuously controlled power supply from C3 to the heater 5, and the humidifier 9, which also has a small heat capacity, uses the wet bulb temperature detected by the quick-response humidity sensor S2 and the controller C1 to control the heating. Compare and calculate the set dry bulb temperature with PID temperature controller C2,
The resulting output signal is sent to SSR unit C3.
The humidification is controlled by continuously controlled power supply from the SSR unit C3 to the humidifier 9.
このような恒温恒湿器において、除湿器７と加
湿器９の間には区画壁８が配設されている。 In such a constant temperature and humidity chamber, a partition wall 8 is disposed between the dehumidifier 7 and the humidifier 9.
この区画壁８は、上端が除湿器底面の中途部に
連設すると共に、調温調湿室３内の循環空気Ｅの
通風路を二分して吸込口３２の中央部迄延出して
いる。 The partition wall 8 has an upper end connected to the middle part of the bottom surface of the dehumidifier, and extends to the center of the suction port 32 by dividing the ventilation path of the circulating air E in the temperature and humidity control chamber 3 into two.
従つて、送風機４の駆動によつて試験室２から

接に除湿器７へ流入する。 Therefore, the circulating air E that flows into the temperature and humidity controlling chamber 3 from the test chamber 2 through the suction port 32 by driving the blower 4 is divided into two parts, and one of the circulating air E1 passes over the humidifier 9. The humidifier 9 generates humidified air containing water vapor, and the other circulating air E2
Since the water is separated from the humidifier 9, it flows directly into the dehumidifier 7 without being humidified.
ここで除湿器７は調温調湿室３の背壁３４との

気流入側である底面が区画壁８により２つに区画

ていない循環空気E2が通過することになる。尚、
除湿器７は調温調湿室３の背壁３４に当接して加
湿された循環空気E2が全て通過するものであつ
てもよい。 Here, the dehumidifier 7 is disposed with a gap 7c between it and the back wall 34 of the temperature and humidity control room 3, and its bottom surface, which is the circulating air inflow side, is divided into two by a partition wall 8. , one side (in the case of the illustrated example, the narrow part) 7
A part of the humidified air E1 passes through a and 7a,
The unhumidified circulating air E2 passes through the other (in the case of the illustrated example, the wide portion) 7b. still,
The dehumidifier 7 may be a device through which all the humidified circulating air E2 comes into contact with the back wall 34 of the temperature and humidity control room 3.
また、区画壁８の除湿器７底面への配設位置は
通過空気の除湿器接触面積と相関関係にあるの
で、加湿空気E1の除湿を少なくする場合には接
触面積を狭くするように設定すればよく、この配
設位置につり除湿作用適宜調節しうる。 In addition, the placement position of the partition wall 8 on the bottom of the dehumidifier 7 has a correlation with the contact area of the passing air with the dehumidifier, so if the dehumidification of the humidified air E1 is to be reduced, the contact area should be set to be narrower. If so, the dehumidification effect can be adjusted as appropriate by hanging at this location.
次ぎに、除湿器７をそれぞれ通過した循環空気
E1，E2は合流して送風口より吐出される。この
ように循環を行つて試験室内を所定温湿度の雰囲
気に調整する。 Next, the circulating air that has passed through the dehumidifier 7
E1 and E2 are combined and discharged from the air outlet. By performing circulation in this manner, the atmosphere in the test chamber is adjusted to a predetermined temperature and humidity.
この発明は、上記の如く構成されているので加
湿された空気が除湿器の除湿作用の全てではなく
一部を受けるため極めて効率的且つ短時間に加湿
できると共に、除湿器の除湿も従来に比べ少なく
てすみ、結露も少なくなるので送風や除湿が阻害
されず機器の小型化や省エネルギーを期すことが
できる。 Since this invention is constructed as described above, the humidified air receives some but not all of the dehumidifying action of the dehumidifier, so it can be humidified very efficiently and in a short time, and the dehumidification of the dehumidifier is also faster than before. Since the amount of water required is small and dew condensation is also reduced, air blowing and dehumidification are not hindered, making it possible to downsize equipment and save energy.
また、二分された一方の空気E1は全面的に加
湿された後、一部は除湿器の幅狭部分を通過し、
残りに加湿されたまま除湿されずに循環するので
温湿度制御の精度を高める。 In addition, after the air E1 is completely humidified, part of it passes through the narrow part of the dehumidifier.
The remaining humidified air circulates without being dehumidified, increasing the accuracy of temperature and humidity control.
更に、試験室内が設定湿度と一致した場合に加
湿器への通電が停止するが、余熱により発生する
水蒸気は除湿器を通過して除湿されるので余分に
湿度を高めることがなく湿度制御の精度が一層向
上する。 Furthermore, when the humidity in the test room matches the set humidity, the supply of electricity to the humidifier is stopped, but since the water vapor generated by residual heat passes through the dehumidifier and is dehumidified, the humidity does not increase excessively and the accuracy of humidity control is improved. further improves.

のチヤンバ構造からなつている。 The chamber body 1 of the constant temperature and humidity chamber shown in FIG.
The chamber structure is similar to that of the constant temperature and humidity chamber shown in FIG. 1, except that a cooler (for low temperature cooling) 6 is disposed between the heater 5 and the dehumidifier 7.

ズヒーター９２の加熱により水蒸気を発生させて
加湿する構成からなる。 That is, the blower 4 uses a horizontal shaft fan having approximately the same length as the width of the test chamber 2 to circulate or stir a wide wind. The heater 5 consists of a nichrome strip wire heater. The cooler 6 and the dehumidifier 7 are evaporators of a refrigerator unit (not shown), and are arranged so as to substantially block the ventilation path of the temperature and humidity control chamber 3. In addition, the humidifier 9 stores humidifying water at a constant level in a flat humidifying pan 91 formed on almost the entire bottom wall surface 33 of the temperature and humidity control room using a level controller (not shown). It is configured to humidify by generating water vapor by heating with a sheathed heater 92 provided.
ここで、除湿器７は調温調湿室３の背壁３４に

つて上昇する傾斜姿勢で保持されていると共に、
該除湿器７の底面上で上昇端側寄りに区画壁８の
上端を連設している。 Here, the dehumidifier 7 is disposed on the back wall 34 of the temperature and humidity control room 3 through a gap, and is held in an inclined position rising toward the back wall 34 side.
The upper end of a partition wall 8 is connected to the bottom surface of the dehumidifier 7 near the rising end.
この区画壁８は、順次下降して吸込口３２の略
中央まで延出し、試験室２内のドレーン２１内又
はその近傍に下端が近接している。 The partition wall 8 gradually descends and extends to approximately the center of the suction port 32, and its lower end is in or near the drain 21 in the test chamber 2.
図示例の場合、吸込口３２の略中央から垂下す

い。 In the illustrated example, the lower end portion 83 hanging down from approximately the center of the suction port 32 is close to the drain 21 via the gap S. Instead of this gap S, the lower end 83 is extended to the bottom wall of the temperature and humidity control room, and a known air inlet structure such as a group of ventilation holes is used to direct the circulating air flowing in from the suction port 32. You can divide it into two.
従つて、吸込口から流入した循環空気は第１図
と同様の流通径路を経て効率的に加湿される。 Therefore, the circulating air flowing in from the suction port is efficiently humidified through the same circulation path as shown in FIG.

湿用水W2の水質劣化を防ぎ、一定純度を維持し
うるので加湿ヒーター乃至空焚防止センサー等の
機器に悪影響を及ぼすことがない。 In addition, the water droplets W1 condensed on the dehumidifier 7 fall or flow down the partition wall 8 along the slope of the dehumidifier 7, and flow down the partition wall 8 to the drain 21 in the test chamber. This prevents the quality of the humidifying water W2 from deteriorating due to water falling into the water tank 91, and maintains a certain level of purity, so there is no adverse effect on equipment such as the humidifying heater or the dry firing prevention sensor.
次ぎに、本実施例においては除湿器７は除湿と
共に冷却も行うが、このほかに低温冷却用の冷却
器６をも設けている。 Next, in this embodiment, the dehumidifier 7 performs cooling as well as dehumidification, but in addition to this, a cooler 6 for low-temperature cooling is also provided.
ここで、従来の方法では、この低温冷却用の冷
却器６と除湿器７とを一台の冷却除湿器で兼用し
ていた。 In the conventional method, a single cooling dehumidifier is used as both the low-temperature cooling cooler 6 and the dehumidifier 7.
そのため、この冷却除湿器を低温冷却に用いる
場合には熱容量を低温冷却用の冷却器と同様大き
く設定しなければならず、この冷却器と除湿器と
における熱交換器の所有能力の違いにより、その
除湿作用を甚だしく大きくなる。 Therefore, when this cooling dehumidifier is used for low-temperature cooling, the heat capacity must be set as large as a cooler for low-temperature cooling, and due to the difference in the heat exchanger capacity between this cooler and dehumidifier, The dehumidification effect becomes extremely large.
従つて、加湿器の加湿能力が前述の従来構成に
みられる、除湿作用を全てうけることからくる障
碍よりも更にその能力が損なわれ、益々エネルギ
ー消費が増大する。 Therefore, the humidifying ability of the humidifier is impaired even more than the problem caused by receiving all the dehumidifying action in the conventional configuration described above, and the energy consumption is further increased.
更に、熱交換器の所有能力の違いにより恒温恒
湿器の持つ能力としての制御範囲も、その上限及
び下限がせばめられてくる。 Furthermore, due to differences in the capabilities of the heat exchangers, the upper and lower limits of the control range of the capabilities of the constant temperature and humidity chamber become narrower.
そこで、この発明では、除湿試験を伴わない低
温試験と、除湿試験を伴なう温湿度試験をそれぞ
れ冷却器６と除湿器７とに区分して別々の冷凍機
ユニツトを用いて行つている。 Therefore, in the present invention, a low temperature test without a dehumidification test and a temperature/humidity test with a dehumidification test are divided into a cooler 6 and a dehumidifier 7, respectively, and are conducted using separate refrigerator units.
これにより、前記兼用の弊害を回避することが
でき、加湿器の小型化やエネルギー消費の省力化
が可能となつた。 This makes it possible to avoid the above-mentioned disadvantages of dual use, making it possible to downsize the humidifier and save energy consumption.
この冷却器６は試験室２を低温冷却する際に駆

ある。 This cooler 6 is driven when cooling the test chamber 2 at a low temperature, and is operated at a predetermined temperature (0 in this embodiment).
℃) is the boundary range, and when cooling to this temperature, the dehumidifier 7 is driven, and when cooling beyond this temperature (in this example, 0°C to -40°C), the cooler 6 is driven. Since the test chamber is cooled at a low temperature, it is possible to easily adjust the test chamber to a constant temperature and humidity atmosphere.
本実施例においては、加湿器を調温調湿室の底
壁面に配設したが、この加湿器は除湿器の下方で
あればその配設位置をとわない。 In this embodiment, the humidifier is placed on the bottom wall of the temperature and humidity control room, but the humidifier can be placed anywhere below the dehumidifier.

A blower, a heater, a dehumidifier, and a humidifier are sequentially installed in the ventilation path of a temperature and humidity control chamber provided in the chamber body of a constant temperature and humidity chamber in the opposite direction to the circulation direction of the air inside the chamber. At the same time, the temperature and humidity of the constant temperature and humidity chamber is controlled continuously according to the set temperature and humidity and the measured value of the sensor that measures the temperature and humidity inside the chamber while continuously driving the dehumidifier. In the humidity control method, circulating air that is drawn into a temperature and humidity control room and passing through a cooling dehumidifier is divided into two parts, one of which is humidified by a humidifier, and then at least a portion of the humidified circulating air is transferred to a portion of the cooling dehumidifier. A constant temperature/humidifier characterized in that the dehumidifying effect of the dehumidifier on the circulating air humidified by the humidifier is reduced by passing the other part directly through the other part of the cooling dehumidifier without humidifying it. How to control humidity. 2. A partition wall that divides the circulating air that is sucked into the temperature and humidity control room and passes through the cooling dehumidifier into two, so that the water dehumidified from the dehumidifier is not guided to the drain and recycled to the humidifying pan of the humidifier.
