ァン１０の運転をも停止させるように形成する。A primary thermostat 20 is installed in the piping that sends water from the outlet header 4 to the evaporator 15, and the equipment 1
For example, set the temperature range of the water sent to 8 from 20℃ to
In the case of 25°C, when the temperature of the outside air is low and the temperature of the water cooled by the cooling unit 1 falls below the upper limit of the setting range of 25°C, the primary thermostat 20 operates to stop watering from the watering tank 5. In order to stop the pump 7, the operation of the pump 7 is stopped, and if the temperature of the water becomes even colder, the operation of the fan 10 is also stopped.

When the temperature of the water sent to the equipment 18 becomes 25°C or higher, the secondary thermostat 21 is activated, and the compressor 1 is operated until the water sent out reaches 25°C or lower.

ことができる。When the temperature of this water falls below the set temperature range of 20° C., the fan 10 can also be stopped to prevent further cooling. In addition, in summer when the temperature of the outside air is high, when the cooling section 1 is naturally cooled, the water is
Operate the compressor 12 only when cooling to 5°C or less is not possible,
Since the evaporator 15 only needs to cool the temperature to the set range, the energy for cooling can be minimized.

。[Effects of the Invention] Since the present invention is configured as described above, when only a reciprocating refrigerator is used, the compressor must be operated at all times regardless of changes in the outside air temperature, which results in a lot of wasted energy. Moreover, it also eliminates the drawback that depending on the natural cooling system that takes heat from outside air or water, the cooling may not reach the desired temperature range depending on the outside air temperature. It is. As a result, the fluid to be cooled can be cooled to a set temperature range with minimum energy in accordance with the temperature of the outside air.

きな温度範囲での冷却が可能になる。In other words, there is a cooling section 1 having a plurality of layers of cooling pipes for cooling the fluid to be cooled, a water sprinkling tank 5 provided above the cooling section 1 for sprinkling water on the cooling section 1, and a water sprinkling tank 5 provided below the cooling section 1. A water sprinkling mechanism consisting of a water receiving tank 16 that receives water, a water supply channel 8 that sends water from this water receiving tank 6 to a water sprinkling tank 5, and a cooling unit 1.
In the cooling device, a cooling device consisting of a fan 10 that generates ventilation to forcibly exhaust the heat released by By forming the cooling fluid from the section 1 to be sent to the outside via the evaporator 15, the cooling device and reciprocating refrigerator (chilling unit) cool the cooling fluid with air or water through a cooling pipe. ) are connected in series, so if these cooling devices and coolers are controlled and operated appropriately, cooling can be achieved over a very wide temperature range.

ことができる。A primary thermostat 20 adjusts the amount of water sprayed and the operation of the fan 10 when the temperature of the fluid to be cooled sent from the cooling unit 1 to the evaporator 15 falls below a set range; By installing a secondary thermostat 21 that operates the cooler appropriately when the temperature of the fluid to be cooled sent out to the outside exceeds a set range, when the temperature of the outside air is low such as in winter, the The temperature of the fluid to be cooled is kept within the set range by cooling only with the cooling device, and if the temperature of the fluid to be cooled falls below the set range using only the cooling device, the primary thermostat 20 stops water sprinkling from the water sprinkling tank 5. It can be adjusted by stopping the operation of the fan 10. On the other hand, when the temperature of the outside air is high such as in the summer and the temperature of the fluid to be cooled cannot be cooled down to the set range by the cooling device alone, the temperature of the fluid to be cooled can be forcedly cooled by operating the cooler to bring the temperature within the set range. The fluid to be cooled can be cooled up to

きる。On the other hand, if an attempt is made to cool the device using only the cooling device, there will be an inconvenience that it will not be able to cool the device completely when the outside air temperature rises to around 30° C. in summer or the like. This inconvenience occurs particularly in the latest equipment that requires cooling water at low temperatures (25°C or lower), but these inconveniences can also be solved by using the above-mentioned cooler that can be forced to cool. .
