Description

  The present invention relates to a temperature adjustment device that includes a refrigeration cycle that circulates refrigerant in the order of a compressor, a condenser, an expansion unit, and an evaporator, and cools temperature-controlled air using the refrigerant flowing in the evaporator as a heat source.

  Such a temperature adjusting device includes, for example, a heating unit in addition to the refrigeration cycle, heats the refrigerant and the temperature adjustment target air in an evaporator to cool the temperature adjustment target air, and the cooled temperature. The temperature of the temperature adjustment target air is adjusted within a target temperature range (for example, a range of target temperature (20 ° C.) ± 0.1 ° C.) by heating the temperature adjustment target air with a heating unit. And the temperature adjustment object air of the target temperature range by which temperature adjustment was carried out is made to supply to the temperature adjustment object space (for example, refer patent document 1).

  In such a temperature adjusting device, drain water is generated when heat exchange is performed between the refrigerant and the temperature adjustment target air in the evaporator. For example, when the temperature control target space is an indoor space where a precision processing machine or the like is installed, steam generated from the precision processing machine is included in the temperature control target air. Therefore, for example, the temperature adjustment target air that has been temperature-controlled by the temperature adjustment device is supplied to the temperature adjustment target space, and the temperature adjustment target air in the temperature adjustment target space is returned to the temperature adjustment device. In a device that circulates temperature control air to and from the target space, steam generated from a precision processing machine is included in the temperature control air that is cooled by the evaporator. Will occur.

  In the conventional temperature control apparatus, since it is necessary to perform some treatment on the drain water, for example, there is provided a drain water drainage facility for discharging drain water generated in the evaporator to the outside of the apparatus. is there. In addition, if a drain water drainage facility is newly provided, the configuration becomes complicated. Therefore, in other conventional temperature control devices, drain water generated in the evaporator is supplied to the evaporation chamber and the heater is heated. There is also one that evaporates the drain water (see, for example, Patent Document 2).

JP 2008-39345 A Japanese Patent No. 3996487

In the thing of the said patent document 2, since it is not necessary to provide a drain water drainage facility newly, the simplification of a structure can be aimed at. However, a new evaporation chamber equipped with a heater has to be provided, which still causes a complicated structure.
Moreover, since the drain water is evaporated by the heating of the heater in the one described in Patent Document 2, heat is newly generated by the heater, and the cold heat of the drain water is simply exhausted. Therefore, the heat already possessed could not be effectively utilized.

  The present invention has been made paying attention to this point, and an object of the present invention is to provide a temperature adjusting device capable of effectively utilizing heat while simplifying the configuration.

In order to achieve this object, the characteristic configuration of the temperature adjusting device according to the present invention is provided with a refrigeration cycle for circulating a refrigerant in the order of a compressor, a condenser, an expansion unit, and an evaporator, and the refrigerant flowing in the evaporator In the temperature adjustment device that cools the temperature-controlled air as a heat source,
Drain water dripping means for dripping drain water generated in the evaporator to the cooling heat exchanger, and a part of the temperature adjustment target air to the drain water dripped to the cooling heat exchanger. A temperature control target fluid different from the temperature control air is passed through the ventilation means and the cooling heat exchanger, and the temperature control target fluid is cooled using the latent heat of evaporation of the drain water. Another temperature adjustment target fluid cooling means to be provided.

According to this characteristic configuration, in the cooling heat exchanger, the drain water is dropped by the drain water dropping means, and a part of the temperature-controlled air is ventilated by the ventilation means to the dripped drain water. As a result, the drain water evaporates, and the air around the cooling heat exchanger is cooled by the latent heat of vaporization at that time. For example, in a factory or the like, in addition to adjusting the temperature of the temperature adjustment target air, it may be required to adjust the temperature of another temperature adjustment target fluid other than the temperature adjustment target air such as compressed air. Therefore, another temperature adjustment target fluid is caused to flow through the cooling heat exchanger by another temperature adjustment target fluid cooling means. As a result, heat exchange is performed between the air around the cooling heat exchanger cooled by the latent heat of evaporation of the drain water and the target fluid for temperature adjustment, or the latent heat of evaporation of the drain water and the target fluid for another temperature control are directly exchanged. Heat exchange can be performed to cool the separate temperature control target fluid. In this way, not only the temperature adjustment target air can be cooled, but also the other temperature adjustment target fluid can be cooled, and the demand for adjusting the temperature of the other temperature adjustment target fluid can be met. And since the heat source at the time of cooling another temperature control object fluid uses the cold heat which drain water has, it is not necessary to newly provide the heat source for cooling another temperature control object fluid. Furthermore, since the drain water is evaporated in the cooling heat exchanger, it is not necessary to newly provide a drain water drainage facility for discharging the drain water to the outside of the apparatus.
From the above, while the structure can be simplified and the cost can be reduced, the temperature control target fluid can be cooled using the cooling heat of the drain water, and the heat can be effectively utilized. A temperature control device can be realized.

  A further characteristic configuration of the temperature adjusting device according to the present invention includes a heating unit that heats the temperature-controlled air that is cooled by using the refrigerant flowing in the evaporator as a heat source, and the ventilation unit is the heating unit. It exists in the point comprised so that a part of said temperature control object air after heating may be ventilated with respect to the said drain water.

  According to this characteristic configuration, the temperature-controlled air to be ventilated with respect to the drain water can be made as dry air as possible with low humidity after being heated by the heating means. As a result, the drain water can be positively evaporated, and the separate temperature adjustment target fluid can be accurately cooled using the latent heat of evaporation of the drain water.

  A further characteristic configuration of the temperature adjustment device according to the present invention is that the ventilation means is configured to freely adjust the ventilation amount of the temperature adjustment target air to be ventilated to the drain water.

According to this characteristic configuration, the ventilation amount of the temperature adjustment target air to be ventilated with respect to the drain water can be adjusted so that the ventilation amount required for cooling the separate temperature adjustment target fluid can be obtained. Cooling of the fluid to be adjusted can be performed reliably.
In addition, since the temperature adjustment target air after being heated by the heating means is adjusted to the target temperature for adjusting the temperature adjustment target space, the temperature adjustment target air is more than necessary for the drain water. When ventilating, the heat for adjusting the temperature of the temperature adjustment target air is wasted. Therefore, for example, when the temperature adjustment target air to be ventilated to the drain water is the temperature adjustment target air heated by the heating means, the minimum required for cooling the separate temperature adjustment target fluid It is possible to adjust the ventilation rate. Thereby, it is possible to prevent the heat for adjusting the temperature of the temperature adjustment target air from being wasted and to further effectively use the heat.

  The temperature control device according to the present invention is further characterized in that a heat transfer liquid cooling means that cools the heat transfer liquid by exchanging heat between the refrigerant and the heat transfer liquid in the evaporator and cooled. A heat exchanger for cooling the temperature adjustment target air that cools the temperature adjustment target air by exchanging heat between the heat transfer liquid and the temperature adjustment target air, and the drain water dripping means is the evaporator. The drain water that is generated and the drain water that is generated in the temperature-controlled air cooling heat exchanger are configured to be dropped onto the cooling heat exchanger.

  When the temperature adjustment target air is cooled by using the refrigerant in the evaporator as a heat source, if the refrigerant and the temperature adjustment target air are heat-exchanged in the evaporator, it is difficult to uniformly cool the temperature adjustment target air. That is, for example, the temperature of the refrigerant flowing throughout the evaporator is different such that the temperature of the refrigerant flowing through the inlet side of the evaporator differs from the temperature of the refrigerant flowing through the outlet side depending on the degree of change in the state of the refrigerant. Difficult to make uniform. Therefore, when the temperature adjustment target air is cooled by the refrigerant in the evaporator, it is difficult to uniformly cool the temperature adjustment target air, and temperature unevenness may occur in the temperature adjustment target air.

  Therefore, according to the present characteristic configuration, the heat transfer liquid cooling means cools the heat transfer liquid using the refrigerant instead of cooling the temperature adjustment target air using the refrigerant in the evaporator. In the heat exchanger for cooling the temperature adjustment target air, the temperature adjustment target air is cooled by exchanging heat between the cooled heat transfer liquid and the temperature adjustment target air. Since the specific gravity of the heat transfer liquid is larger than that of the refrigerant, the heat transfer liquid can be made uniform in temperature when heat exchange is performed between the heat transfer liquid and the temperature adjustment target air. Therefore, the temperature adjustment target air can be cooled to a uniform temperature without temperature unevenness. In addition, drain water is generated in the heat control air cooling heat exchanger, and this drain water is also dropped into the cooling heat exchanger by the drain water dropping means. Thus, the drainage water generated in the evaporator and the cold heat of the drainage water generated in the temperature control target air cooling heat exchanger can be used to efficiently separate the temperature control target fluid in the cooling heat exchanger and It can be cooled accurately.

The separate temperature control target fluid Q is allowed to flow through the cooling heat exchanger 13 and the separate temperature control target fluid Q is cooled using the latent heat of evaporation when the drain water W evaporates.
Since the temperature adjusting device according to the present invention includes the drain water dripping means 14, the ventilation means 15, and the separate temperature adjustment target fluid cooling means 16, each will be described below.

  The separate temperature adjustment target fluid cooling means 16 allows the separate temperature adjustment target fluid Q to flow through the cooling heat exchanger 13 and cools the separate temperature adjustment target fluid Q using the latent heat of evaporation of the drain water W. It is configured. As shown in FIG. 2, the cooling heat exchanger 13 is configured by, for example, a fin tube type heat exchanger, and the separate temperature adjustment target fluid flow path 21 through which the separate temperature adjustment target fluid Q flows. Are connected to the inlet side and the outlet side of the tube 13a of the cooling heat exchanger 13, respectively. As a result, the ambient air around the cooling heat exchanger 13 is cooled by the latent heat of evaporation of the evaporated drain water W, and the temperature is separately adjusted to flow through the cooled air and the tube 13a of the cooling heat exchanger 13. The target fluid Q is subjected to heat exchange, or the latent heat of evaporation of the drain water W and the separate temperature adjustment target fluid Q are directly exchanged to cool the separate temperature adjustment target fluid Q. The separate temperature control target fluid cooling means 16 includes a separate temperature control target fluid passage 21.

  The temperature adjusting device is provided with a third reheater 22 for exchanging heat with another temperature adjustment target fluid Q cooled by the cooling heat exchanger 13 and a part of the refrigerant A discharged from the compressor 1. Yes. As a result, the separate temperature adjustment target fluid Q is cooled by the cooling heat exchanger 13 using the drain water W as a heat source, and then heated to the desired temperature by the refrigerant A in the third reheater 22 to be supplied as intended.

In the refrigerant circuit 5, a branching / merging passage 23 branched from between the compressor 1 and the condenser 2 and joined between the condenser 2 and the expansion valve 3 is provided. The branching / merging channel 23 includes a first branching / merging channel 24, a second branching / merging channel 25, and a third branching / merging channel 26 connected in parallel with each other.

A third refrigerant regulating valve 29 and a third reheater 22 are provided in the third branch joint channel 26 in order from the upstream side in the flow direction of the refrigerant A, so that the refrigerant A can be intermittently adjusted and the flow rate of the refrigerant A can be adjusted. Yes.

The operation when the temperature adjustment target air P and the separate temperature adjustment target fluid Q are adjusted will be described.
First, in order for the heat transfer liquid B to acquire the cold heat of the refrigerant A flowing through the evaporator 4, the refrigerant A and the heat transfer liquid B are exchanged in the evaporator 4, and the heat transfer liquid B is used in the refrigerant A. Is cooled to the desired temperature. For example, the heat transfer liquid B is cooled to a desired temperature by adjusting the flow rate of the refrigerant A flowing through the evaporator 4 and the flow rate of the heat transfer liquid B. For example, the temperature of the heat transfer liquid B supplied to the evaporator 4 is 20 ° C., and the temperature of the heat transfer liquid B that has passed through the evaporator 4 is 17 ° C.

  In this way, the temperature control target air P is cooled to a desired temperature by the heat transfer liquid B in the temperature control target air cooling heat exchanger 7 using the cold heat acquired by the heat transfer liquid B. For example, by adjusting the flow rate of the heat transfer liquid B based on detection information of a temperature sensor (not shown) that detects the temperature of the temperature adjustment target air P that has passed through the temperature adjustment target air cooling heat exchanger 7. Then, the temperature adjustment target air P is cooled to a desired temperature of 18 ° C. ± 1 ° C., for example. At this time, for example, the temperature of the heat transfer liquid B supplied to the temperature adjustment target air cooling heat exchanger 7 is 17 ° C., and the heat transfer liquid B that has passed through the temperature adjustment target air cooling heat exchanger 7 The temperature is 18 ° C. On the other hand, the temperature of the temperature control target air P supplied to the temperature control target air cooling heat exchanger 7 is set to 25 ° C.

  Then, the temperature adjustment target air P cooled by the temperature adjustment target air cooling heat exchanger 7 is heated to a desired temperature by the second reheater 12 and supplied to the temperature adjustment target space. For example, the temperature adjustment is performed by adjusting the opening degree of the second refrigerant adjustment valve 28 based on detection information of a temperature sensor (not shown) that detects the temperature of the temperature adjustment target air P that has passed through the second reheater 12. The target air P is precisely adjusted to a desired temperature of 20 ± 0.1 ° C., for example.

In the evaporator 4, the heat transfer liquid B is cooled by exchanging heat between the refrigerant A and the heat transfer liquid B. At this time, since the drain water W is generated, the drain water W is recovered by the drain pan 17. . Further, in the heat exchanger 7 for cooling the temperature adjustment target air, the heat transfer liquid B and the temperature adjustment target air P are heat-exchanged to cool the temperature adjustment target air P, but at this time, drain water W is generated. The drain water W is collected by the drain pan 17. For example, when a precision processing machine or the like is installed in the temperature control target space, steam generated from the precision processing machine is included in the temperature control target air. Therefore, if the temperature adjustment target air P is circulated between the temperature adjustment target space and the temperature adjustment device, a large amount of drain water W is generated in the heat adjustment target air cooling heat exchanger 7.
The drain water W collected in the drain pan 17 of the evaporator 4 and the temperature control target air cooling heat exchanger 7 is guided to the cooling heat exchanger 13 through the drain water supply path 18, and the cooling heat exchanger 13. It is dripped at the heat exchanger 13 for cooling from above.

  The temperature adjustment target air P heated to the desired temperature by the second reheater 12 is not only supplied to the temperature adjustment target space but also partly branched by the ventilation path 19 to the cooling heat exchanger 13. The water is guided and drained to the drain water W dropped into the cooling heat exchanger 13. Thereby, although the temperature of the drain water W dripped at the heat exchanger 13 for cooling is 9-15 degreeC, for example, this drain water W evaporates and the surroundings of the heat exchanger 13 for cooling by the latent heat of vaporization at that time The air is cooled and heat is exchanged between the cooled air and the target fluid Q for another temperature control, or the target temperature is controlled separately by direct heat exchange between the latent heat of evaporation of the drain water W and the target fluid Q for temperature control. The fluid Q is cooled. Then, the ventilation amount of the temperature adjustment target air P to be ventilated with respect to the drain water W is adjusted by adjusting the opening degree of the ventilation amount adjustment valve 20. For example, the temperature of the separate temperature adjustment target fluid Q supplied to the cooling heat exchanger 13 is 25 ° C., and the temperature of the separate temperature adjustment target fluid Q that has passed through the cooling heat exchanger 13 is the target temperature (for example, 18 ° C.). The ventilation rate of the temperature adjustment target air P to be ventilated with respect to the drain water W is adjusted so as to be. Thereby, for example, it is possible to adjust to the minimum ventilation amount necessary for cooling the separate temperature adjustment target fluid Q, and wastefully exhausting the heat for adjusting the temperature of the temperature adjustment target air P. This makes it possible to further effectively use heat. Such adjustment of the air flow rate of the temperature control target air P is performed, for example, at the initial stage of use of the apparatus, and thereafter, the adjusted constant air flow rate is set.

  The separate temperature control target fluid Q cooled by the cooling heat exchanger 13 is heated to a desired temperature by the third reheater 22 and supplied to a target location where the separate temperature control target fluid Q is used. . For example, by adjusting the opening degree of the third refrigerant adjustment valve 29 or the like based on detection information of a temperature sensor (not shown) that detects the temperature of the separate temperature adjustment target fluid Q that has passed through the third reheater 22, The temperature adjustment target fluid Q is adjusted to a desired temperature of 20 ° C., for example.

  Incidentally, since the first reheater 9 is provided in the liquid circuit 6, the first refrigerant adjustment valve is in a no-load state where it is not necessary to adjust the temperature of the temperature adjustment target air P or the separate temperature adjustment target fluid Q. By opening the valve 27, the heat transfer liquid B is heated with the refrigerant A in the first reheater 9. Then, by supplying the heat transfer liquid B heated by the first reheater 9 to the evaporator 4, freezing or the like in the evaporator 4 is prevented.

[Another embodiment]
(1) In the above-described embodiment, each of the first reheater 9, the second reheater 12, and the third reheater 22 can be implemented instead of a heating means such as an electric heater, for example. Further, the first reheater 9 and the third reheater 22 can be omitted.

(2) In the above-described embodiment, the ventilation means 15 ventilates a part of the temperature adjustment target air P after being heated by the second reheater 12. The temperature control target air P after being heated by the second reheater 12 is not limited. For example, in FIG. 1, as indicated by a two-dot chain line, a part of the temperature adjustment target air P before being supplied to the temperature adjustment target air cooling heat exchanger 7 can be ventilated to the drain water W. . In this case, as shown by a dotted line in FIG. 1, a flow path for leading a part of the temperature adjustment target air P before being supplied to the temperature adjustment target air cooling heat exchanger 7 to the cooling heat exchanger 13. A valve is provided in the valve, and the ventilation amount of the temperature adjustment target air P to be ventilated to the drain water W by the valve can be adjusted.

(3) In the above embodiment, the separate temperature adjustment target fluid Q is compressed air, but the temperature adjustment target air and the separate temperature adjustment target fluid may be different fluids, for example, for cooling various devices. It is also possible to use the cooling water to be used as another temperature control target fluid Q.

(4) In the above embodiment, the liquid circuit 6 is provided, and the heat transfer liquid B cooled by the refrigerant A in the evaporator 4 is supplied to the temperature adjustment target air cooling heat exchanger 7, thereby providing a temperature control target. Although the air P is cooled, for example, the refrigerant A and the temperature adjustment target air P may be heat-exchanged in the evaporator 4 so that the temperature adjustment target air P is directly cooled by the refrigerant A. In this case, the drain water dropping means 14 drops only the drain water W generated in the evaporator 4 to the cooling heat exchanger 13.
