本(ben)發(fa)明涉及一種計(ji)費系(xi)統，具體是一種低成本(ben)一拖多(duo)中央空調內機分攤計(ji)費系(xi)統。

背景技術：

隨(sui)(sui)著經濟發展，中央空(kong)調(diao)(diao)(diao)(diao)(diao)，特別是(shi)水(shui)系(xi)統(tong)(tong)中央空(kong)調(diao)(diao)(diao)(diao)(diao)被(bei)廣(guang)泛(fan)應用于辦公樓、商業中心等大型(xing)(xing)(xing)場所(suo)。中央空(kong)調(diao)(diao)(diao)(diao)(diao)水(shui)系(xi)統(tong)(tong)具有溫(wen)濕度舒適、溫(wen)差小(xiao)、老少皆宜等優(you)點。中央空(kong)調(diao)(diao)(diao)(diao)(diao)水(shui)系(xi)統(tong)(tong)是(shi)由室外主機、管道、循環(huan)泵(beng)、風機盤(pan)管和其他(ta)控制設(she)備共同(tong)組成，主機是(shi)整個(ge)系(xi)統(tong)(tong)的(de)核心，利(li)用制冷(leng)劑相(xiang)(xiang)變(bian)原理實(shi)現(xian)(xian)制冷(leng)制熱，產生的(de)冷(leng)熱水(shui)通(tong)過(guo)管道，在循環(huan)泵(beng)的(de)作用下，進入各個(ge)風機盤(pan)管末端與室內空(kong)氣進行冷(leng)熱交換(huan)，實(shi)現(xian)(xian)空(kong)氣調(diao)(diao)(diao)(diao)(diao)節。隨(sui)(sui)著大型(xing)(xing)(xing)中央空(kong)調(diao)(diao)(diao)(diao)(diao)的(de)發展，出現(xian)(xian)了小(xiao)型(xing)(xing)(xing)的(de)戶式中央空(kong)調(diao)(diao)(diao)(diao)(diao)水(shui)系(xi)統(tong)(tong)，相(xiang)(xiang)比大型(xing)(xing)(xing)機組，小(xiao)型(xing)(xing)(xing)戶式中央空(kong)調(diao)(diao)(diao)(diao)(diao)也是(shi)采用一拖(tuo)多結構(gou)，只是(shi)供冷(leng)面積(ji)相(xiang)(xiang)對變(bian)小(xiao)，結構(gou)簡單(dan)。

根據中(zhong)(zhong)央空(kong)(kong)調(diao)(diao)水(shui)系(xi)(xi)統的(de)(de)系(xi)(xi)統結構(gou)(gou)特點(dian)，是采用(yong)(yong)一拖多的(de)(de)結構(gou)(gou)，一臺主(zhu)機(ji)可以為(wei)多臺室內(nei)機(ji)供冷(leng)(leng)供熱，可以有效提高設備的(de)(de)利用(yong)(yong)率，降(jiang)低單位(wei)面(mian)積的(de)(de)安(an)裝(zhuang)成本，因此(ci)中(zhong)(zhong)央空(kong)(kong)調(diao)(diao)水(shui)系(xi)(xi)統相對分(fen)體空(kong)(kong)調(diao)(diao)，具有使(shi)用(yong)(yong)面(mian)積大(da)，制冷(leng)(leng)量大(da)，機(ji)組功耗大(da)等(deng)特點(dian)。因此(ci)，在大(da)型商業(ye)中(zhong)(zhong)心(xin)，辦(ban)公(gong)樓(lou)等(deng)非(fei)同一使(shi)用(yong)(yong)主(zhu)體的(de)(de)公(gong)共場所(suo)，就(jiu)會產(chan)生(sheng)中(zhong)(zhong)央空(kong)(kong)調(diao)(diao)使(shi)用(yong)(yong)費用(yong)(yong)的(de)(de)收(shou)費問題。

目前(qian)，市面上存在(zai)很多(duo)中央(yang)空調的計費方法。

電費計量型中央空調計費方法(fa)：

計(ji)(ji)費原理：電(dian)費計(ji)(ji)量型就是通(tong)過計(ji)(ji)量空調(diao)末端的(de)(de)用(yong)電(dian)量，再根據用(yong)電(dian)量換算為冷量，統計(ji)(ji)中(zhong)央空調(diao)系統中(zhong)各(ge)(ge)用(yong)戶的(de)(de)總冷量，再根據各(ge)(ge)用(yong)戶的(de)(de)冷量比例來分攤(tan)費用(yong)。

優點(dian)：電量(liang)參數容易計量(liang)，管理核算容易。

缺點：沒有考(kao)慮(lv)冷凍水流量，冷量，溫度的變化，沒有考(kao)慮(lv)風機盤管類型，脫離“誰(shui)使(shi)用誰(shui)付費(fei),用多(duo)少(shao)交多(duo)少(shao)”原則，令客戶沒有節能(neng)意(yi)愿。

時間型中央空調計費(fei)方(fang)法：

計(ji)(ji)(ji)費原理：將風(feng)機盤管的(de)三速(su)開關、電動二(er)通(tong)閥的(de)電源都(dou)接(jie)入采集器，采集器在檢(jian)測到二(er)通(tong)閥及風(feng)速(su)信號數(shu)據上傳計(ji)(ji)(ji)算機監控系統進行分析處理，將各檔位(wei)狀態時(shi)間累(lei)計(ji)(ji)(ji)，通(tong)過給定(ding)(ding)時(shi)間型系數(shu)轉換成基準時(shi)間，按(an)照核定(ding)(ding)的(de)價格(ge)，進行計(ji)(ji)(ji)費。

優點：時(shi)間參數容(rong)易(yi)計量，管理核(he)算容(rong)易(yi)，可(ke)定時(shi)或實時(shi)對終端(duan)進行各種操作(zuo)。

缺點：沒有考慮冷凍水(shui)流量，冷量，溫度的變化(hua)，脫離“誰(shui)使用誰(shui)付(fu)費，用多少(shao)交多少(shao)”原則，令客戶沒有節能(neng)意愿(yuan)。

面積型(xing)中央空調計(ji)費方法：

計費原理：對中央(yang)空(kong)調(diao)系統(tong)計費與節能不(bu)大重(zhong)視(shi)，在空(kong)調(diao)系統(tong)設計與施工中未(wei)考慮實際(ji)使用環境(jing)，收費時采(cai)用“面(mian)積分(fen)攤(tan)法”，簡單(dan)地以使用面(mian)積來分(fen)攤(tan)中央(yang)空(kong)調(diao)主機(包(bao)括水泵、冷面(mian)積平攤(tan)型卻塔等)費用。

優點：面積(ji)參數容(rong)易計量，管理核算(suan)容(rong)易。

缺點：沒有考慮不同工(gong)作(zuo)時(shi)間(jian)的單(dan)位面積用冷(leng)量(liang)的差異。不同工(gong)作(zuo)場所的單(dan)位面積用冷(leng)量(liang)的差異，間(jian)接計費(fei)方法脫離“誰使用誰付費(fei),用多少交(jiao)多少”原則(ze)，令客戶沒有節能意愿。

冷凍(dong)水流(liu)量型中央(yang)空調計費方法：

計費原理：計流表(biao)通過傳感器將信號(hao)傳輸(shu)給采集終端，系統(tong)接收到信號(hao)后進行計數和(he)處理，并把結(jie)果(guo)儲存下來。

優(you)點：計量水流量的變化又克服了時(shi)間型計費不足。可定時(shi)或實時(shi)對下轄的終端進行各種操(cao)作。

缺點：忽視了水(shui)溫(wen)的變化。不能準(zhun)確計算冷量(liang)。脫離“誰(shui)使用誰(shui)付費(fei)，用多少(shao)交多少(shao)”原(yuan)則，令客(ke)戶沒有節能意(yi)愿。

精確(que)能量型中央(yang)空調計費方(fang)法：

計費原(yuan)理：在進(jin)回(hui)水(shui)管(guan)道(dao)各安裝(zhuang)(zhuang)一(yi)支配(pei)對的高精度溫度傳(chuan)感器，并(bing)在回(hui)水(shui)管(guan)道(dao)上安裝(zhuang)(zhuang)一(yi)臺電磁流量(liang)(liang)計。用流量(liang)(liang)計計量(liang)(liang)流經的冷(leng)凍(dong)水(shui)流量(liang)(liang)的大小，用進(jin)水(shui)、回(hui)水(shui)的溫差來計算能量(liang)(liang)的損(sun)耗，同時(shi)將(jiang)溫度信(xin)號(hao)和(he)流量(liang)(liang)信(xin)號(hao)接入能量(liang)(liang)積算儀。監控系統(tong)根(gen)據能量(liang)(liang)積算儀進(jin)行(xing)精確直接計費法精確能量(liang)(liang)型計費。

優點：通(tong)過流量、溫度的(de)瞬間(jian)變化計算精準，方式透(tou)明，更容易為用戶(hu)所接受，實現(xian)“誰使用誰付費,用多少交多少”原則(ze)。

缺點：但(dan)系統復雜設備成本高，傳感器防干擾工(gong)藝有待完善(shan)。

中(zhong)央空(kong)調(diao)計(ji)(ji)(ji)費系(xi)統伴隨著中(zhong)央空(kong)調(diao)的廣(guang)泛應用而出現(xian)了多種不同的計(ji)(ji)(ji)費方(fang)(fang)法，各(ge)種方(fang)(fang)法都可以在一(yi)定程度(du)上解(jie)決收費問題(ti)但又存在各(ge)自不合理(li)(li)的地方(fang)(fang)。中(zhong)央空(kong)調(diao)的計(ji)(ji)(ji)費系(xi)統需要滿(man)足計(ji)(ji)(ji)費原理(li)(li)科學合理(li)(li)，精(jing)度(du)高，系(xi)統結(jie)構不復(fu)雜，整套系(xi)統成本低，計(ji)(ji)(ji)費效果能得到用戶(hu)滿(man)意的必要條件。

電費(fei)計量(liang)型：根據(ju)用電量(liang)大小轉化為用冷量(liang)大小，然后再根據(ju)用冷比(bi)例進行分配電量(liang)，過程(cheng)復雜(za)精度(du)低(di)。

時間(jian)(jian)計量型：根據(ju)用戶使(shi)用時間(jian)(jian)的(de)大小進行(xing)轉換，利用時間(jian)(jian)進行(xing)計費，雖然方法簡單但是精(jing)度低，不科學。

面積計量型：根據用(yong)(yong)(yong)(yong)戶(hu)的(de)使用(yong)(yong)(yong)(yong)面積進行計算收費，是相對(dui)落后的(de)一種計量方法，用(yong)(yong)(yong)(yong)多用(yong)(yong)(yong)(yong)少都(dou)一樣，與系統使用(yong)(yong)(yong)(yong)情況無關(guan)，用(yong)(yong)(yong)(yong)戶(hu)不(bu)認可。

冷(leng)(leng)凍(dong)(dong)水流量型：根(gen)據進(jin)(jin)入用(yong)戶(hu)的冷(leng)(leng)凍(dong)(dong)水的流量大小進(jin)(jin)行(xing)計算(suan)，類似水表一(yi)樣，沒(mei)有結(jie)合冷(leng)(leng)凍(dong)(dong)水的溫度有效性進(jin)(jin)行(xing)綜合計算(suan)，不合理。

精確能量型：根據溫(wen)度和流量等綜合(he)計算，精度高，但是整套系統復雜，成本高，穩定性差。

綜上所述，現有(you)中央空(kong)調計費系(xi)統存在各種不(bu)合理、不(bu)科學的情(qing)況。

技術實現要素：

本發明(ming)的工(gong)作原理是(shi)：

1、采用分戶接入電源的(de)結構(gou)設計

傳統(tong)中央空調采用主(zhu)機(ji)(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)設(she)計，主(zhu)電(dian)(dian)(dian)(dian)源(yuan)(yuan)直接接入(ru)主(zhu)機(ji)(ji)(ji)，風(feng)機(ji)(ji)(ji)盤(pan)(pan)管末端(duan)由(you)室內溫控(kong)(kong)器控(kong)(kong)制，電(dian)(dian)(dian)(dian)源(yuan)(yuan)就近接入(ru)，即(ji)主(zhu)機(ji)(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)(yuan)與風(feng)機(ji)(ji)(ji)盤(pan)(pan)管供(gong)(gong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)不(bu)同(tong)(tong)(tong)(tong)(tong)，中央空調運行(xing)時(shi)，主(zhu)機(ji)(ji)(ji)耗電(dian)(dian)(dian)(dian)量需(xu)采取一定(ding)方法進行(xing)均(jun)分(fen)。采用分(fen)戶接入(ru)電(dian)(dian)(dian)(dian)源(yuan)(yuan)的(de)結構設(she)計，每個(ge)(ge)房間的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)零火相(xiang)(xiang)(xiang)性相(xiang)(xiang)(xiang)同(tong)(tong)(tong)(tong)(tong)，由(you)同(tong)(tong)(tong)(tong)(tong)一電(dian)(dian)(dian)(dian)源(yuan)(yuan)分(fen)出，各個(ge)(ge)房間電(dian)(dian)(dian)(dian)源(yuan)(yuan)零火相(xiang)(xiang)(xiang)同(tong)(tong)(tong)(tong)(tong)，接入(ru)控(kong)(kong)制器，共(gong)同(tong)(tong)(tong)(tong)(tong)為主(zhu)機(ji)(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)，即(ji)主(zhu)機(ji)(ji)(ji)供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)(yuan)由(you)所有風(feng)機(ji)(ji)(ji)盤(pan)(pan)管末端(duan)共(gong)同(tong)(tong)(tong)(tong)(tong)供(gong)(gong)電(dian)(dian)(dian)(dian)。針對小型中央空調主(zhu)機(ji)(ji)(ji)功率(lv)相(xiang)(xiang)(xiang)對較小，只有一個(ge)(ge)末端(duan)運行(xing)時(shi)，主(zhu)機(ji)(ji)(ji)電(dian)(dian)(dian)(dian)源(yuan)(yuan)由(you)該末端(duan)所在(zai)用戶提(ti)供(gong)(gong)。當有多個(ge)(ge)末端(duan)同(tong)(tong)(tong)(tong)(tong)時(shi)使(shi)用時(shi)，系統(tong)供(gong)(gong)電(dian)(dian)(dian)(dian)由(you)所有運行(xing)末端(duan)共(gong)同(tong)(tong)(tong)(tong)(tong)提(ti)供(gong)(gong)。
