制冷剂供给装置 Refrigerant supply means

技术领域 FIELD

本发明涉及为向空调机等冷却设备填充制冷剂而使用的制冷剂供给装置。 The present invention relates to a refrigerant supplying apparatus such as air conditioners and the cooling device filled with the refrigerant used.

还有,在上述图8所示的现有技术中,需要向制冷剂容器31放温水的大型供水设备33,液体制冷剂的加热效率也不好。 There are a large water supply equipment, in the prior art shown in FIG. 8, it is necessary to put the heated refrigerant container 3133, the liquid refrigerant in the heating efficiency is not good. 还有,在制冷剂容器31使用金属的场合,由水引起的金属劣化等就成了问题。 Further, in the case of using a metal 31 refrigerant container, metal deterioration caused by water became a problem.

另一方面,在上述专利文献1记载的制冷剂填充装置中,必须对制冷剂贮气瓶设置加热器,这也使设备规模变大,液体制冷剂的加热效率也不好。 On the other hand, the refrigerant filling apparatus described in Patent Document 1, it is necessary to set the heater of the refrigerant storage cylinder, which also makes the device size becomes large, the heating efficiency of the liquid refrigerant is not good. 在这种场合也是,在制冷剂容器31为替换式时,由于有加热器32,替换作业很麻烦。 In this case also, when the refrigerant container 31 is replaceable, since the heater 32, the replacement work is troublesome.

图2详细表示反馈配管9上的制冷剂加热装置10的构成等。 FIG 2 shows in detail a feedback pipe 9 on the refrigerant heating apparatus 10 configured like. 制冷剂加热装置10包括加热器15和在该加热器15的下游侧设在反馈配管9上的减压阀16。 The refrigerant heating apparatus 10 includes a heater 15 and a downstream side of the heater 15 is provided in the feedback pressure reducing valve 16 of the pipe 9. 加热器15相当于用于加热流过反馈配管9的液体制冷剂的本发明的加热装置。 The heater 15 corresponds to the heating apparatus according to the present invention through the feedback of the liquid refrigerant pipe 9 for the heating flow. 加热器15包括卷绕在反馈配管9上的电热线15a。 The heater 15 comprises a heating wire 15a wound on a feedback pipe 9. 图3中以正视图来表示加热器15的外观。 In FIG 3 a front view showing the appearance of the heater to 15. 如图3所示,加热器15包括内装有电热线15a的外罩17、与反馈配管9连接的管18、设在该管18的两端的连接器19、20。 3, the heater 15 comprises a heating wire 15a that has the outer cover 17, and a feedback pipe 9 pipe 18 is connected, at both ends of the tube 18 is a connector 19, 20. 在外罩17的内部中,电热线15a卷绕在管18上。 Inside the housing 17, the electrical wire 15a is wound on the tube 18. 另一方面,减压阀16用于使由加热器15加热而汽化了的气体制冷剂的压力降低。 On the other hand, the pressure relief valve 16 for the gas refrigerant is heated by the heater 15 is reduced and vaporized. 加热器15内装有恒温器,一旦接通,就由恒温器保持在40℃以下的加热温度。 The heater 15 has a thermostat built, once turned on, maintained at a heating temperature of 40 ℃ by a thermostat. 在该实施方式中,减压阀16的设定压力为「约0.9Mpa」。 In this embodiment, the set pressure relief valve 16 is "about 0.9Mpa." 如图2所示,在该实施方式中,压力泵2使「约2.0Mpa」的液体制冷剂通过反馈配管9流到加热器15,液体制冷剂汽化而变为「约2.0Mpa」的气体制冷剂。 As shown, in this embodiment, the pressure pump 2 so that the liquid refrigerant 2 "to about 2.0Mpa" 9 flows to the heater via a feedback pipe 15, the liquid refrigerant becomes vaporized "about 2.0Mpa" gas refrigerant agents. 此后,该气体制冷剂通过减压阀16,使压力下降至作为制冷剂容器1的压力的「0.7~0.8Mpa」。 Thereafter, the gas refrigerant passes through the pressure reducing valve 16, the pressure drops to a pressure of the refrigerant as the container 1 is "0.7 ~ 0.8Mpa."

图4以示意图表示控制盘13执行的加热器15的动作。 Figure 4 shows the operation executed by the control panel 13 of the heater 15 to FIG. 控制盘13在制冷剂供给装置的启动后,水箱压力报警信号「接通」的话,就把加热器15的电源「接通」。 The control panel 13 after the start of the refrigerant supplying apparatus, the tank pressure alarm signal "ON", then put the heater power supply 15 is "ON." 此后,控制盘13在来自温度传感器12的容器温度的信号变为「6℃」时,把加热器15的电源「关断」。 Thereafter, the control panel 13 at the tank temperature signal from the temperature sensor 12 becomes "6 ℃", the power of the heater 15 is "off." 通过使加热器15的电源在「接通」到「关断」之间操作,加热器15由温调器反复进行接通和关断。 By making the heater power source 15 in the "ON" operation between the "off" the heater 15 is turned on and off repeatedly by a temperature controller.

图5(a)~(d)以时序图表示与加热器15的控制有关的各种参数变动的一个例子。 FIG 5 (a) ~ (d) shows an example of control of the heater 15 and various parameters relating to variation in a timing chart. 图5(a)表示水箱压力的变动,图5(b)表示水箱压力报警信号的变动,图5(c)表示加热器电源的变动,图5(d)表示相当于环境温度的容器温度的变动。 FIG 5 (a) represents a pressure variation in the tank, FIG. 5 (b) indicates variation in the tank pressure alarm signal, FIG. 5 (c) represents a change in the heater power, FIG. 5 (d) indicates the temperature of the container corresponds to the ambient temperature change. 从图5可知,随着环境温度的降低,容器温度降低的话,水箱压力就会降低。 Seen from FIG. 5, as the ambient temperature decreases, the vessel temperature is lowered, then, the tank pressure will decrease. 于是,水箱压力降低至作为设定压力的「0.5MPa」的话,水箱压力报警信号就「接通」,加热器电源就「接通」。 Thus, as the tank pressure is reduced to a set pressure "0.5MPa" then, the tank pressure alarm signal is "ON", the power supply to the heater "ON." 此后,加热器15就由恒温器保持在40℃以下的加热温度。 Thereafter, the heater 15 is held at the heating temperature of the thermostat 40 ℃. 这样,流过反馈配管9的液体制冷剂就被加热、汽化,通过反馈配管9,气体制冷剂流入制冷剂容器1,制冷剂容器1的内压就被合理保持。 Thus, a feedback pipe 9 flows through the refrigerant liquid to be heated, vaporized by the feedback pipe 9, the gas refrigerant flows into the refrigerant container 1, the internal pressure of the refrigerant container 1 was kept reasonable. 此时,水箱压力上升至作为减压阀16的设定压力的「约0.9MPa」附近。 At this point, the tank pressure rises to the set pressure relief valve as close to 16, "about 0.9MPa." 此后,容器温度变为「6℃」的话,加热器电源就变为「关断」,水箱压力就变为超过「0.5MPa」的容许温度以上。 Thereafter, the vessel temperature was changed to "6 ℃", then the heater power becomes "off", the tank pressure becomes more than an allowable temperature "0.5MPa" in. 此处,容器温度随着环境温度的变化,即季节变化而变化,因而如图5(d)所示,冬季低于「6℃」,到春天就超过「6℃」。 Here, the temperature of the container with changes in ambient temperature, i.e., change of seasons, and thus in FIG. 5 (d) shown below in winter "6 ℃", in the spring is more than "6 ℃." 因此,加热器15在进入冬季时,电源就「接通」,电源保持「接通」,直到容器温度变为「6℃」。 Thus, when the heater 15 into the winter, the power to "ON", the power remains "ON" until the vessel temperature became "6 ℃."

按照以上说明了的该实施方式的制冷剂供给装置,制冷剂供给装置启动,压力泵2进行动作,从而制冷剂容器1中的液体制冷剂被汲起、压送,通过供给配管3和计量·注入机4被提供给制品5,液体制冷剂就被填充到制品5中。 Means refrigerant supplying apparatus starts in accordance with the refrigerant supplied above described manner of this embodiment, a pressure pump 2 is operated, so that the refrigerant containing liquid refrigerant 1 is pumped onwards, pressure-fed by the supply pipe 3 and the metering · injection machine 4 is provided to the article 5, and the liquid refrigerant is filled into the article 5.

此处,在压力泵2的下游侧,流过供给配管3的液体制冷剂的一部分流向反馈配管9而返回制冷剂容器1。 Here, the downstream side pressure of the pump 2, flows through the supply pipe flow to the feedback portion of the liquid refrigerant pipe 3 and return the refrigerant container 9 1. 还有,在压力泵2的上游侧,供给配管3中的制冷剂压力,即水箱压力由第2压力计11来测量,制冷剂容器1的温度(容器温度)由温度传感器12来检测。 Further, the upstream side pressure of the pump 2, the pressure of the refrigerant supply pipe 3, i.e., the tank pressure measured by the second pressure gauge 11, the temperature (container temperature) of the refrigerant vessel 1 detected by the temperature sensor 12. 此时,控制盘13根据被测量的水箱压力,使加热器15接通,从而流过反馈配管9的液体制冷剂就被加热、汽化。 At this time, the control panel 13 according to the tank pressure is measured, the heater 15 is turned on, so that the flow through the feedback pipe 9 to the liquid refrigerant is heated, vaporized. 还有,在加热器15的下游侧,汽化了的气体制冷剂由减压阀16减压。 At the downstream side of the heater 15, the gas refrigerant vaporized by the pressure reducing valve 16. 因此,减压了的气体制冷剂返回制冷剂容器1中,制冷剂容器1中由气体制冷剂来补充液体制冷剂由于汲起而容积减少了的量。 Thus, a pressure gas refrigerant returns the refrigerant vessel 1, the refrigerant gas from the container 1 to replenish the refrigerant pumped from the liquid refrigerant because of the reduced amount of volume. 因此,根据需要,即水箱压力变为「0.5MPa」以下时,能把气体制冷剂确实提供给制冷剂容器1,能保障对制品5的液体制冷剂的提供动作。 Therefore, if necessary, that the tank pressure becomes "0.5MPa" less refrigerant gas can indeed provide to the refrigerant container 1 can provide protection against the action of liquid refrigerant products 5. 另一方面,控制盘13根据被测量的水箱压力,使加热器15关断,从而流过反馈配管9的液体制冷剂的加热就会停止,液体制冷剂就直接返回制冷剂容器1。 On the other hand, the control panel 13 according to the tank pressure is measured, the heater 15 is turned off, so that the flow through the feedback pipe 9 of the heating will stop the liquid refrigerant, the liquid refrigerant returns directly to the cryogen vessel 1. 因此,容器温度充分高时,制冷剂容器1中的气体制冷剂不会增加到超过必要的量。 Thus, when the container temperature is sufficiently high, the refrigerant in a refrigerant gas in the container does not increase more than necessary amount. 因此,容器温度变为「6℃」以上时,能确实停止对制冷剂容器1的气体制冷剂的提供,能控制制冷剂容器1中的压力过度上升。 Accordingly, the temperature of the container becomes more "6 ℃", can be reliably stops supplying the gas refrigerant to the refrigerant container 1, to control the refrigerant pressure in the container 1 rises excessively. 这样,就能够根据水箱压力和容器温度使加热器15高效地动作。 Thus, the heater 15 can be efficiently operated according to a pressure tank and temperature of the vessel.

在该实施方式中,用气体制冷剂来补充制冷剂容器1,因而在反馈配管9上仅设有加热器15和减压阀16,所以与以前例那样用大型设备加热制冷剂容器31的情况相比,简化了构成。 In this embodiment, the refrigerant gas container 1 to replenish the refrigerant, thus only a feedback 9 is provided on the pipe heater 15 and the pressure reducing valve 16, so, as with the previous embodiments a large apparatus for heating refrigerant container 31 where compared to simplify the constitution. 并且,加热损失按构成简化了的量而减少了。 And, by heating loss amount constituting a simplified reduced. 因此,能够使用于对制冷剂容器1之中以气体制冷剂来补充的构成相对紧凑化,能够提高液体制冷剂的加热效率。 Thus, it is possible to use a refrigerant in a gas container to replenish the refrigerant is relatively compact configuration, it is possible to improve the heating efficiency of the liquid refrigerant. 并且,能够通过对返回制冷剂进行加热来提高制冷剂容器31内的气体压力,在冬季等气温低时也能够很快汲起制冷剂。 And it is possible to increase the gas pressure within the cryogen vessel 31 through the refrigerant return heating temperature is low like in the winter it is possible to quickly drain from the refrigerant.

还有,在该实施方式中,反馈配管9、加热器15和减压阀16的构成与制冷剂容器1分开设置,还容易从制冷剂容器1拆下反馈配管9。 In addition, in this embodiment, the feedback pipe 9 constituting the heater 15 and the refrigerant container 16 and the pressure reducing valve 1 is provided separately, a feedback pipe 9 is also easily removed from a refrigerant container. 因此,即使制冷剂容器1是替换式的场合,也能够使制冷剂容器1的替换作业变得容易。 Thus, even if the refrigerant is a replaceable container 1 occasion, it is possible to replace the refrigerant container 1 becomes easy job.

另外,本发明不限于上述实施方式,在不越出发明的宗旨的范围内,也可以变更构成的一部分,按以下方式来实施。 Further, the present invention is not limited to the above embodiments, in a range not beyond the gist of the invention, part of the configuration may be changed, be implemented in the following manner.
