Description

空调系统有效热量、能效的计算方法和能流图显示方法 技术领域
本发明涉及空调系统领域,具体涉及空调系统有效热量、能效的计算方法和能流图显示方法。
背景技术
在国内,公共建筑面积约占城镇总面积的15%,此比重随着我国城乡一体化建设战略的开展而快速增长。普遍看来,在写字楼、商场、医院、酒店等大型建筑中都采用了中央空调制冷系统。在一座建筑中,中央空调能耗占建筑总能耗的40%~60%,此类建筑的单位空调能耗面积电耗为80~200kwh/m2,为普通住宅建筑的5~8倍。因而在大型公共建筑中,节能显得尤为重要,而对于已成型的中央空调系统节能的主要手段则是能耗的监测与测量。国内外学者针对中央空调系统的能耗测试和节能改造都做了大量的研究和分析。
中央空调系统按照散热介质分为:风冷中央空调系统和水冷中央空调系统。
如图1所示,水冷中央空调系统包括三个子系统:冷冻液(通常采用冷冻水)系统,压缩机2、冷却水系统。在冷冻水系统中,冷冻水流经压缩机2的蒸发器后被制冷,然后流入经过建筑物的管道,并进入末端的风机盘管,在风机盘管中吸收建筑物的热量后,重新流入压缩机2的蒸发器再次被制冷,如此循环,冷冻液泵16提供冷冻水循环的动力。在冷却水系统中,冷却水流经压缩机2的冷凝器被加热,然后流出冷凝器并进入冷却塔进行散热,然后再次回流至压缩机2的冷凝器被加热,冷却水泵提供冷却水循环的动力。压缩机2 工作时,制冷剂不断循环,在蒸发器中吸收热量从而对冷冻水进行制冷,在冷凝器中释放热量从而对冷却水进行加热。
风冷中央空调系统与水冷中央空调系统的不同之处在于:没有冷却水系统,压缩机2的热量直接通过冷凝器散至空气中。
为了评价中央空调系统的能耗性能,业界提出了COP(Coefficient Of Performance,能效),COP=从被制冷区域(例如大厦)吸收的热量/中央空调系统的总耗电量。具体而言,从被制冷区域(例如大厦)吸收的热量=cρVΔt,其中,c表示冷冻液的比热容,ρ表示冷冻液的密度,V表示冷冻液的单位体积流量,Δt表示该制冷区域的入口管路位置的冷冻液的温度与出口管路位置的冷冻液的温度之差。
然而,经过研究发现,这种方法计算得到的COP并不准确,从而导致对中央空调系统的耗能性能评价也不准确。
发明内容
经过研究发现,由于冷冻液在被制冷区域中的管路中流动的过程中与管路存在摩擦力,尤其是管路末端的风机盘管的管径较小且长度较长,冷冻液与管路之间的摩擦力更大,加上冷冻液流动过程中自身摩擦(例如产生涡流而形成冷冻液内部的摩擦等),这些摩擦产生的热量也会引起冷冻液温度的上升,也就是说,现有技术测量得到的上述热量=cρVΔt,并非完全是从被制冷区域吸收的热量,也就是存在一部分无效的热量,从而造成计算得到的能效COP不准确。
另外,从能量守恒的角度来看,当整个冷冻液系统的各种参数保持不变的情况下(例如冷冻液泵的转速、冷冻液的流速等保持不变的情况下),冷冻液的总机械能保持不变,但是由于冷冻液泵对冷冻液做功,因此做功转化为冷冻 液的摩擦热量,如前所述,这种摩擦热量包含了冷冻液与管路的摩擦与冷冻液之间的摩擦。
为了克服现有技术的不足,提高计算得到的冷冻液从被制冷区域吸收的热量的准确度,本发明提供了一种计算装置计算空调系统有效热量的方法,其中,在空调系统中,冷冻液从入口位置流经路过被制冷区域的管路到达出口位置,所述方法包括如下步骤:根据所述冷冻液在所述管路中流动产生的摩擦热量计算所述冷冻液从所述被制冷区域吸收的有效热量。

具体实施方式
现结合附图,对本发明的较佳实施例作详细说明。
如图1所示,是本发明空调系统一种实施例的原理图。该空调系统包括压缩机2、冷冻液泵16、流量计13、第一温度计11、第二温度计14、第一压力计12和第二压力计15,以及路过被制冷区域18的管路17,管路17包括与被制冷区域18进行热交换的末端管路171(例如风机盘管)。在冷冻液泵16的 驱动下,冷冻液从入口位置流经路过被制冷区域18的管路17而到达出口位置。第一温度计11和第一压力计12安装于入口位置,以分别测量入口位置冷冻液的第一温度T1和第一压力P1,第二温度计14和第二压力计15安装于出口位置,以分别测量出口位置冷冻液的第二温度T2和第二压力P2。
冷冻液泵16用于提供冷冻液循环的动力,其位置可以设置在冷冻液循环回路的除被制冷区域18之外的任意地方。
如图2所示,计算装置计算空调系统有效热量的方法一种实施例的流程图,该方法包括如下步骤。
S11、计算装置接收第一温度计11、第二温度计14、第一压力计12、第二压力计15和流量计13分别发送的第一温度T1、第二温度T2、第一压力P1、第二压力P2和冷冻液的单位流量。该单位流量可以是单位质量流量或单位体积流量。
如图3所示,计算装置可以通过有线或无线方式与第一温度计11、第二温度计14、第一压力计12、第二压力计15和流量计13进行通信,从而获得第一温度T1、第二温度T2、第一压力P1、第二压力P2和单位流量。本计算装置可以是任何形式的硬件,例如个人电脑、服务器、移动智能设备等,或者专门用于计算空调系统有效热量的硬件设备。
S12、计算装置计算第一温度T1与第二温度T2之差,即,入口位置的冷冻液与出口位置的冷冻液之间的温度差Δt,计算装置计算第一压力P1与第二压力P2之差,即,入口位置的冷冻液与出口位置的冷冻液之间的压力差ΔP。
S13、计算装置基于冷冻液的单位流量以及温度差Δt,计算冷冻液从入口位置到达出口位置过程中吸收的总热量Q。该单位流量可以是单位质量流量 或单位体积流量。具体而言,该单位流量是单位质量流量情况下,则Q=cmΔt,其中,c表示冷冻液的比热容,m表示冷冻液的质量流量。可以理解,在计算Q时还可以利用修正参数对上述公式Q=cmΔt进行修正,以使计算得到的Q与实际值更加接近,该修正参数以及修正算法可以根据实验得到,例如,在一些实施例中Q=kcmΔt,0.95≦k≦1.1。若该单位流量是单位体积流量,则Q=cρVΔt,其中,c表示冷冻液的比热容,V表示冷冻液的单位体积流量,ρ表示冷冻液的密度。可以理解,在计算Q时还可以利用修正参数对上述公式Q=cρVΔt进行修正,以使计算得到的Q与实际值更加接近,该修正参数以及修正算法可以根据实验确定,例如,在一些实施例中Q=kcρVΔt,0.95≦k≦1.1。
S14、基于冷冻液的单位体积流量V以及压力差ΔP,计算冷冻液在管路17中流动产生的摩擦热量W冷冻液。具体而言,W冷冻液=fl=ΔPSv=ΔPV,其中,f表示冷冻液在管路17中受到的摩擦力,l表示冷冻液从入口位置到达出口位置移动的距离,S表示管路17的横截面,v表示冷冻液流速,也即是说,摩擦热量W冷冻液等于压力差ΔP与单位体积流量V之乘积。可以理解,在计算W冷冻液时还可以利用修正参数对上述公式进行修正,以使计算得到的W冷冻液与实际值更加接近,该修正参数以及修正算法可以根据实验确定,例如,在一些实施例中W冷冻液=kΔPV,0.95≦k≦1.1。
S15、将总热量Q减去摩擦热量W冷冻液,得到冷冻液从被制冷区域18实际吸收的有效热量Q有效。可以理解,在计算Q有效时还可以利用修正参数对上述公式进行修正,以使计算得到的Q有效与实际值更加接近,该修正参数以及修正算法可以根据实验确定,例如,在一些实施例中Q有效=k(Q-W冷冻液),0.95≦k≦1.1。
在另一个实施例中,还可以利用压差计替代第一压力计12和第二压力计15,压差计直接测量得到第一压力与第二压力之差ΔP,然后将ΔP通过有线或无线的方式发送给计算装置,因而计算装置不需要再计算ΔP。
本发明首次提出冷冻液从入口位置到达出口位置过程中吸收的总热量中包含了冷冻液摩擦产生的无效的摩擦热量W冷冻液,并依据摩擦热量W冷冻液计算冷冻液实际从被制冷区域吸收的热量(有效热量),而计算有效热量的具体算法还可以有很多,但是均需依据摩擦热量W冷冻液进行计算,因此这些算法均在本发明的保护范围之内。
如图4所示,在一个实施例中,为了得到比现有技术更准确的能效COP,本发明还提供了一种计算装置计算空调系统能效的方法,包括如下步骤:根据冷冻液在管路17中流动产生的摩擦热量W冷冻液计算空调系统的总能效或子能效。本计算装置可以是任何形式的硬件,例如个人电脑、服务器、移动智能设备等,或者专门用于计算空调系统能效的硬件设备。
具体而言,本计算装置在步骤S15之后,还进一步执行以下步骤。
S16、获取空调系统的总耗电量或空调系统的子系统的耗电量。
S17、根据摩擦热量W冷冻液计算有效热量,并计算有效热量与空调系统的总耗电量或空调系统的子系统的耗电量的比值,得到空调系统的总能效COP或子能效COP
例如,对于水冷中央空调系统,可以分别获取各个子系统的耗电量E冷冻液系统、E压缩机和E冷却液系统,从而可以分别计算冷冻液系统、压缩机2或冷却液系统的子能效COP,或者空调系统的总能效COP
由于现有技术计算得到的能效是不准确的,因此,现有技术基于其计算的能效对空调系统进行的控制也是不准确的,为了克服现有技术的这个不足,本 发明还提供了一种空调系统的控制方法,包括如下步骤:根据冷冻液在管路17中流动产生的摩擦热量W冷冻液控制所述空调系统的运行,由于考虑了摩擦热量W冷冻液,因此对空调系统的控制更加准确。
具体而言在本控制方法中,根据上述实施例计算得到的总能效COP控制空调系统的运行,即对空调系统的冷冻液泵16、压缩机2、冷却水泵等运行部件的至少一者的运行参数进行控制。
如图5和图6所示,为了更加形象地体现空调系统的能量流动,本发明还提供了一种空调系统能流图的显示方法,包括如下步骤:根据冷冻液在管路17中流动产生的摩擦热量W冷冻液产生空调系统的能流图,具体而言包括如下步骤。
S21、获取上述根据摩擦热量W冷冻液计算得到的有效热量Q有效,以及空调系统产生或吸收的除有效热量之外的无效热量。该无效热量可以包括上述摩擦热量W冷冻液、压缩机2产生的热量中传递到冷冻液、冷却液中的热量,冷冻液泵16传递到冷冻液的热量、冷却液泵31传递到冷却液的热量、冷却液在冷却液管路中摩擦产生的热量等。
S22、在显示设备上显示有效热量带、无效热量带以及有效热量和无效热量的输送方向,其中,有效热量带的宽度和无效热量带的宽度分别表示有效热量的大小(数值)和无效热量的大小(数值)。例如,有效热量越大,则有效热量带的宽度越大,反之,有效热量越小,则有效热量带的宽度越小,无效热量亦然。
如图6所示,是能流图的一种实施例的示意图。其中箭头方向表示各种热量的流动方向,有效热量带Q1表示冷冻液从被制冷区域吸收的有效热量,无 效热量带Q2表示冷冻液摩擦产生的无效热量(包含了摩擦热量W冷冻液)的数值,无效热量带Q3表示压缩机产生的无效热量的数值,无效热量带Q4表示冷却液在冷却液管路段摩擦产生的无效热量的数值,最终,有效热量以及无效热量都经过冷却塔散到大气中。
该能流图可以清楚地显示空调系统的有效热量与无效热量的相对大小,给空调系统的运行维护人员提供决策所需信息。
如图7所示,是空调系统有效热量的计算装置100另一种实施例的框图,该计算装置100包括处理器101和存储设备102,该存储设备102存储有指令,该指令被处理器101执行为计算空调系统有效热量的方法,计算空调系统有效热量的方法可以是上述任一实施例的计算空调系统有效热量的方法。
如图8所示,是空调系统能效的计算装置200另一种实施例的框图,该计算装置200包括处理器201和存储设备202,该存储设备202存储有指令,该指令被处理器201执行为计算空调系统能效的方法,计算空调系统能效的方法可以是上述任一实施例的计算空调系统能效的方法。
如图9所示,是空调系统的控制装置300另一种实施例的框图,该控制装置包括处理器301和存储设备302,该存储设备302存储有指令,该指令被处理器301执行为空调系统的控制方法,空调系统的控制方法可以是上述任一实施例的空调系统的控制方法。
应当理解的是,以上实施例仅用以说明本发明的技术方案,而非对其限制,对本领域技术人员来说,可以对上述实施例所记载的技术方案进行修改,或者对其中部分技术特征进行等同替换;而所有这些修改和替换,都应属于本发明所附权利要求的保护范围。
