濃度を上げている。In the heat pump with a heating tower, the antifreeze circulating in the antifreeze path 5 is
, it collects heat from the air, gives heat to the heat pump 4, cools itself, and returns to the heating tower 1. When the antifreeze absorbs more water than the air and its concentration reaches a certain point away from the freezing point, the capacity of the heat pump 4 is reduced by a certain value or the amount of heat collected by the heating tower 1 is reduced. By operating a dedicated antifreeze concentration device 2, the amount of dilution of the antifreeze solution is suppressed, or the concentration is increased by concentrating it.

In this case, there is not much margin for diluting the antifreeze, and the antifreeze concentrating device 2 for concentrating the antifreeze must be made large, resulting in high costs.

。By configuring the operation method of the heating tower as described above, the heating tower bypass piping and control valve, the antifreeze flow rate control device, or the heating tower air volume control device are provided as the outside air heat collection control mechanism, and the outside air humidity detector and It is equipped with an antifreeze temperature detector and controls the outside air heat collection control mechanism so that the antifreeze temperature reaches a predetermined temperature when the outside air humidity is high, so it has a simple configuration, consumes less energy, and prevents excessive dilution of the antifreeze. , stable control of antifreeze concentration in the heating tower can be ensured.
先ず始めに、本発明の前提となる事項に付いて概要を説
明する。本発明者等の経験によれば、ヒーティングタワ
ーにつき下記のことが判明している。First, an overview of the premise of the present invention will be explained. According to the experience of the present inventors, the following has been found regarding heating towers.
外気湿度が高い時はヒーティングタワーの集熱特性が良
く、定格集熱量以上の集熱を行なうことができると同時
に不凍液の希釈が早まる。When the outside air humidity is high, the heating tower has good heat collection characteristics, and can collect more heat than the rated amount of heat collection, while at the same time diluting the antifreeze faster.
１年間で外気湿度が高い気象条件が長期間継続するのは
、１１．１２月、３．４月の期間が大半を占め、この期
間は比較的外気温度が高い期間である。また、外気温度
が高い時にヒーティングタワーの集熱特性が向上するの
は当然のことである。Weather conditions with high outside air humidity continue for a long period of time most of the time in November, December, and March and April, and these periods are periods when the outside air temperature is relatively high. Furthermore, it is natural that the heat collection characteristics of the heating tower improve when the outside air temperature is high.
外気湿度が高い時には、集熱量と希釈量とは略比例し、
集熱量が増加する。また、外気温度が高い時は不凍液温
度も高くなる。When the outside air humidity is high, the amount of heat collected and the amount of dilution are approximately proportional,
The amount of heat collected increases. Furthermore, when the outside temperature is high, the antifreeze temperature also becomes high.
また、ヒーティングタワーにおいて、定格値以上の集熱
を行ない不凍液温度が定格値以上になっている時は、ヒ
ーティングタワーは定格値以上の能力を発揮している。Furthermore, when the heating tower collects heat in excess of the rated value and the antifreeze temperature exceeds the rated value, the heating tower is exhibiting an ability greater than the rated value.
即ち外気湿度が高い時にはヒーティングタワーは定格値
以上の能力を発揮しているが、一方では必要以上に不凍
液の濃度の希釈を早めていることになる。この時、外気
集熱量制御機構を作動させて集熱量を減少させると、不
凍液温度は低下し、不凍液温度が定格値まで低下すると
、ヒートポンプの能力は定格値となりヒーティングタワ
ーの集熱量も定格値となる。In other words, when the outside air humidity is high, the heating tower exhibits a capacity exceeding its rated value, but on the other hand, the concentration of the antifreeze solution is diluted more quickly than necessary. At this time, when the outside air heat collection amount control mechanism is activated to reduce the amount of heat collection, the antifreeze temperature will drop, and when the antifreeze temperature drops to the rated value, the heat pump capacity will become the rated value and the heat collection amount of the heating tower will also be at the rated value. becomes.
本発明は上記事項を考慮して、設備コストが安価で省エ

例を図面に基づいて説明する。The present invention takes the above matters into consideration and is an operating method for a heating tower that is inexpensive in equipment cost, energy saving, and capable of stably controlling the concentration of antifreeze. Embodiments of the present invention will be described below based on the drawings.

る。In the heat pump with a heating tower having the above configuration, when the humidity value detected by the outside air humidity detector 9 is below a certain value, the control unit 10 controls the bypass piping 7 by the control valve 8 regardless of the temperature detected by the antifreeze temperature detector 6. The heating tower 1 is closed and the entire amount of antifreeze is circulated to the heating tower 1. Further, when the humidity value detected by the outside air humidity detector 9 exceeds a certain value, the control valve 8 is activated, and a part of the circulating antifreeze passes through the bypass piping 7, bypasses the heating tower 1, and is distributed to the heating tower 1. It is set to reduce the amount of antifreeze. Therefore, when the detected humidity value of the outside air humidity detector 9 is below a certain value, the control unit 10 circulates the entire amount of antifreeze to the heating tower 1, but when the detected humidity value exceeds a certain value, a part of the antifreeze is circulated. bypass and
Since the amount of heat collected by the heating tower 1 is reduced, the antifreeze temperature is lowered. This bypass amount of antifreeze can be increased until the antifreeze temperature reaches the set temperature of the antifreeze temperature detector 6.

In the figure, 11 is an antifreeze flow control valve that controls the flow rate of antifreeze circulating in the antifreeze path 5, and 12 is the antifreeze flow control valve 11.
This is a control unit that controls the operation of the antifreeze circulation pump P and the drive and rotation speed of the antifreeze circulation pump P.

になるから省エネルギーとなる。In the heat pump with a heating tower having the above configuration, the control unit 12 throttles the antifreeze flow control valve 11 or reduces the rotation speed of the antifreeze circulation pump P when the humidity value detected by the outside air humidity detector 9 is above a certain level. It is set. Therefore, when the humidity value detected by the outside air humidity detector 9, that is, the humidity of the outside air is above a certain level, the control unit 12 throttles the antifreeze flow control valve 11 or reduces the rotation speed of the circulation pump P.
Since the amount of heat collected by the heating tower 1 is reduced, the antifreeze temperature is lowered. This amount of antifreeze circulation decreases until the antifreeze temperature reaches the set temperature. Here, reducing the rotational speed of the circulation pump P reduces the power of the pump P, resulting in energy savings.

Therefore, when the humidity value detected by the outside air humidity detector 9, that is, the humidity of the outside air is above a certain value, the control unit 13 stops or reduces the rotation speed of the fans 1a and 1b, respectively, and reduces the air volume of the heating tower 1. Therefore, the amount of heat collected by the heating tower 1 is reduced. The air volume of the heating tower 1 is decreased until the temperature detected by the antifreeze temperature detector 6 reaches a predetermined value.

In the above case, some of the fans of the heating tower 1 are stopped or their rotational speed is reduced until the antifreeze temperature reaches a predetermined value, and the fan of the heating tower 1 is stopped.
It is sufficient if the structure is configured to reduce the amount of heat collected.
