Description

直膨熱回收節能方法及裝置 Direct expansion heat recovery energy saving method and device

本發明屬空調技術領域,特別係指一種直膨多重熱回收節能方法及裝置,尤適於應用在要求溫度、濕度控制之場所,本發明僅需啟動壓縮機,藉由熱回收,即可同時具有冷卻、除濕、再熱與加濕功能。 The invention belongs to the technical field of air conditioners, and particularly relates to a direct expansion multiple heat recovery energy-saving method and device, which is particularly suitable for application in a place where temperature and humidity control are required. The invention only needs to start a compressor, and by heat recovery, it can simultaneously With cooling, dehumidification, reheat and humidification.

我國為海島型氣候的地方,一年四季中,大部份日子為多濕的天氣,各種產業為求達成產品品質的提昇或開發高科技的技術,已認知到空調溫控濕控的重要性。伴隨著時代的進步,各種產業為求達成產品品質的提昇或開發高科技的技術,其工作環境皆需要求恆溫恆濕的狀態,又如設置於資料中心中之諸多電子設備皆設有電路板及電子元件,倘若資料中心之周圍環境過於乾燥,電路板及電子元件之間容易產生靜電而造成損壞,亦或周圍環境過於潮濕,電路板及電子元件長期處於該環境下容易發生鏽蝕之缺失,因此諸如資料中心或其他工作環境均須要設置高效率的恆溫恆濕空調設備。 China is an island-type climate. In most of the year, most of the days are wet weather. Various industries have realized the importance of temperature control and humidity control in order to achieve product quality improvement or develop high-tech technology. . Along with the progress of the times, various industries seek to achieve product quality improvement or develop high-tech technology, and their working environment needs to be in a state of constant temperature and humidity, and many electronic devices installed in the data center are provided with circuit boards. And electronic components, if the surrounding environment of the data center is too dry, the static electricity is easily generated between the circuit board and the electronic components, or the surrounding environment is too humid, and the circuit board and electronic components are prone to rust in the environment for a long time. Therefore, high-efficiency constant temperature and humidity air conditioning equipment must be installed in data centers or other working environments.

一般恆溫恆濕空調設備處理空氣的方式,是將室內空氣通過冷卻除濕盤管,使空氣同時作冷卻除濕兩種處理,直到達到低於室內空氣溫濕度要求的露點溫度後,再送風至室內,使室內空氣溫濕度同時降低。但在運轉過程中,室內空氣溫度比濕度容易先達到設定點。為了維持溫度 恆定,而冷卻除濕盤管可繼續除濕,因此在空氣通過冷卻除濕盤管後,設置加熱器加熱空氣,使室內空氣溫度維持恆定,直到室內空氣濕度達到設定點後,才控制降低冷卻除濕盤管的能量,惟利用電熱作為再熱裝置,其造價雖低,然而運轉電費卻很浪費。即傳統直膨恆溫恆濕系統的壓縮機只有冷卻與除濕功能,再熱與加濕功能都須採用電熱加熱器與電熱加濕器,為其缺失。 Generally, the constant temperature and humidity air conditioning equipment processes the air by passing the indoor air through the cooling and dehumidifying coil, so that the air is simultaneously cooled and dehumidified, until the dew point temperature lower than the indoor air temperature and humidity is reached, and then the air is sent to the room. The indoor air temperature and humidity are simultaneously reduced. However, during operation, the indoor air temperature is easier to reach the set point than the humidity first. In order to maintain the temperature Constant, while the cooling dehumidification coil can continue to dehumidify, so after the air passes through the cooling dehumidification coil, the heater is set to heat the air, so that the indoor air temperature is kept constant until the indoor air humidity reaches the set point, then the cooling and dehumidification coil is controlled to be lowered. The energy, but the use of electric heat as a reheat device, its cost is low, but the running electricity bill is very wasteful. That is to say, the compressor of the conventional direct expansion constant temperature and humidity system has only the cooling and dehumidifying functions, and the reheating and humidifying functions must be replaced by an electric heater and an electric humidifier.

再者,傳統的熱交換器熱量散熱(或吸熱)均以控制該熱交換 器的冷媒或空氣(或水)的流量,來達到所需的熱傳量,或溫、濕度條件,例如,控制熱交換器一次側流體(冷媒)的流量與溫差,以達到所需的熱交換量(高溫或低溫),或者是控制熱交換器二次側流體(水或空氣)的流量與溫差,以達到所需的熱交換量(高溫或低溫)。但因壓縮機冷媒吐出高壓側屬高壓氣體,一是流量較不易控制,二是控制冷媒流量、壓力變化時,會間接影響到壓縮機的運轉。 Moreover, the heat dissipation (or heat absorption) of the conventional heat exchanger controls the heat exchange. The flow of refrigerant or air (or water) to achieve the required heat transfer, or temperature and humidity conditions, for example, to control the flow and temperature difference of the primary side fluid (refrigerant) of the heat exchanger to achieve the desired heat Exchange volume (high or low temperature), or control the flow rate and temperature difference of the secondary side fluid (water or air) of the heat exchanger to achieve the required heat exchange rate (high temperature or low temperature). However, because the compressor refrigerant discharges high-pressure gas is high-pressure gas, first, the flow rate is difficult to control, and second, when controlling the refrigerant flow rate and pressure change, it will indirectly affect the operation of the compressor.

因冷媒的系統不易控制,故有二次冷媒的系統,例如,冷凍 的滷水系統、空調的冰水系統或熱水系統,以二次冷媒作為冷卻、除濕、加熱之用途,但系統會更複雜而龐大。亦即習用熱交換器散熱(或吸熱)均以控制該熱交換器的一次側流體(滷水、冰水或熱水等二次冷媒)的流量溫差,來達到所需的熱傳量,或溫、濕度條件,為其缺失。 Because the refrigerant system is not easy to control, there is a secondary refrigerant system, for example, freezing The brine system, the air conditioning ice water system or the hot water system uses secondary refrigerant as cooling, dehumidification and heating, but the system is more complicated and bulky. That is, the conventional heat exchanger heats (or absorbs heat) to control the temperature difference of the flow of the primary side fluid (secondary refrigerant such as brine, ice water or hot water) to achieve the required heat transfer, or temperature. , humidity conditions, for which it is missing.

本案發明人鑒於前述習用技術之缺失,積其多年實際從事空 調產品之設計施工等專業知識,經不斷研究、改良後,終有本發明之研發成功,公諸於世。 In view of the lack of the aforementioned conventional techniques, the inventor of the present case actually worked on the space for many years.

請參閱第1圖之傳統基本的冷凍循環壓焓圖,由圖可知其包括有: Please refer to the traditional basic refrigeration cycle pressure map of Figure 1, which can be seen as follows:

1.壓縮過程a-b(壓縮機) W c =G×(h b -h a ) 1. Compression process ab (compressor) W c = G × ( h b - h a )

2.冷凝過程b-c(冷凝器)Q c =G×(h b -h c ) 2. Condensation process bc (condenser) Q c = G × ( h b - h c )

3.節流過程c-d(膨脹閥)h d =h c 3. Throttling process cd (expansion valve) h d = h c

4.蒸發過程d-a(蒸發器)Q e =G×(h a -h d ) 4. Evaporation process da (evaporator) Q e = G × ( h a - h d )

壓縮機的運轉平衡Q c =Q e +W c Operating balance of the compressor Q c = Q e + W c

Qc與Qe若不平衡時,壓縮機會因高、低壓異常而跳機。 If Qc and Qe are unbalanced, the compressor will trip due to high and low voltage abnormalities.

請再參閱第2圖之本發明冷凍循環壓焓圖,由圖可知其包括有: Please refer to the frozen cycle pressure map of the present invention in FIG. 2, which can be seen from the following figures:

1.壓縮過程a-b(壓縮機) W c =G×(h b -h a ) 1. Compression process ab (compressor) W c = G × ( h b - h a )

2.冷凝過程b-c(冷凝器) Q c =Q c1+Q c2 2. Condensation process bc (condenser) Q c = Q c 1 + Q c 2

Q c1=G(h b -h X )=G f1×C f1×△T 1 Q c 1 =G(h b -h X )= G f 1 × C f 1 ×△ T 1

Q c2=Q c -Q c1=Q c -G f1×C f1×△T 1 Q c 2 =Q c -Q c 1 =Q c - G f 1 ×C f 1 ×△ T 1

註:在固定條件下Qc=常數,所以精確控制Qc1的值即可精確控制Qc2的值。 Note: Qc=constant under fixed conditions, so the value of Qc1 can be precisely controlled by precisely controlling the value of Qc1.

3.節流過程c-d(膨脹閥)h d =h c 3. Throttling process cd (expansion valve) h d = h c

4.蒸發過程d-a(蒸發器)Q c =Q e1+Q e2 4. Evaporation process da (evaporator) Q c = Q e 1 + Q e 2

Q e1=G(h r -h d )=G f2×C f2×△T 2 Q e 1 =G(h r - h d )= G f 2 ×C f 2 ×△ T 2

Q e2=Q e -Q e1=Q e -G f2×C f2×△T 2 Q e 2 =Q e -Q e 1 =Q e - G f 2 ×C f 2 ×△ T 2

在固定條件下Qe=常數,所以精確控制Qe1的值即可精確控制Qe2的值。 Qe = constant under fixed conditions, so precise control of the value of Qe1 can accurately control the value of Qe2.

壓縮機的運轉平衡Q c =Q e +W c Operating balance of the compressor Q c = Q e + W c

(Q c1+Q c2)=(Q e1+Q e2)+W c (Q c 1 +Q c 2 )=( Q e 1 + Q e 2 )+ W c

Qc1與Qc2,Qe1與Qe2自己形成互補的關係,所以合成總量Qc、 Qc1 and Qc2, Qe1 and Qe2 form a complementary relationship, so the total amount of Qc,

Qe與Wc平衡容易,不易造成壓縮機高、低壓異常而跳機。 Qe and Wc are easy to balance, and it is not easy to cause high and low pressure abnormalities of the compressor and tripping.

The quantity (Qc2), that is to say the total amount of heat dissipation in the condensation cycle condensation process is limited (under fixed conditions), the total amount of heat dissipation - heat dissipation = the required heat dissipation amount, ie Q c -Q c 1 =Q c 2 .

本發明吸熱過程以至少2個蒸發器(EVP1~2)串連,第2蒸發器所需的吸熱量(Q e2),不是控制第2蒸發器的一次側流體(冷媒)的流量溫差,而是比例式控制第1蒸發器的吸熱量(Q e1),也就是在第2圖上的吸熱過程線上形成Y點,讓Y點可以左右移動,進而達到精確地控制第2蒸發器所需的吸熱量(Q e2),也就是說冷凍循環蒸發過程吸熱總量是有限的(在固定條件下),吸熱總量-吸熱量=所需的吸熱量即Q e -Q e1=Q e2Endothermic process of the present invention at least two evaporators (EVP1 ~ 2) connected in series, the heat absorption (Q e 2) required for the second evaporator, the second evaporator instead of controlling the primary-side fluid (refrigerant) flow temperature, Rather, proportionally control the heat absorption (Q e 1 ) of the first evaporator, that is, form a Y point on the endothermic process line on the second drawing, so that the Y point can be moved left and right, thereby achieving precise control of the second evaporator. The required heat absorption (Q e 2 ), that is to say the total amount of heat absorption in the freezing cycle evaporation process is limited (under fixed conditions), the total heat absorption - the heat absorption = the required heat absorption, ie Q e -Q e 1 = Q e 2 .

本發明前述熱回收加濕器加濕量的計算:在一個開放式水箱,水從水表面的蒸發,依賴於水溫對應的飽和濕度比、空氣中的濕度比,空氣與水的接觸面積(含水平面及水面下),以及表面之上的空氣的速度。蒸 發的水的量可以表示為:G h =(θA 1+C3A2)(X s -X) The calculation of the humidification amount of the heat recovery humidifier of the present invention: in an open water tank, the evaporation of water from the water surface depends on the saturation humidity ratio corresponding to the water temperature, the humidity ratio in the air, and the contact area of the air and water ( The water level and the water surface), and the velocity of the air above the surface. The amount of water evaporated can be expressed as: G h = ( θA 1 + C 3 A 2 ) (X s - X )

公式說明: Formula description:

Gh=每小時蒸發的水的量(公斤/小時) G h = amount of water evaporated per hour (kg/hr)

θ=(C1+C2V)=蒸發係數(kg/m2h) θ = (C1 + C2V) = evaporation coefficient (kg / m 2 h)

C1=常數(無單位)在固定條件之下 C1 = constant (no unit) under fixed conditions

C2=常數(無單位)在固定條件之下 C2 = constant (no unit) under fixed conditions

C3=常數(kg/m2h)在固定條件之下 C3 = constant (kg/m 2 h) under fixed conditions

V=空氣的速度在水面上方(m/s) V = the speed of the air above the water surface (m / s)

A1=水平面上空氣與水的接觸面積(m2) A1=contact area of air and water on the horizontal plane (m 2 )

A2=水平面下微氣泡空氣與水的接觸面積(m2) A2 = contact area of microbubble air with water in the horizontal plane (m 2 )

Xs=在該水溫的飽和空氣水的濕度比(kg/kg) X s = humidity ratio of saturated air water at this water temperature (kg/kg)

X=空氣中的濕度比(kg/kg) X = humidity ratio in air (kg/kg)

注意!該單位θ(kg/m2h)、V(m/s)不匹配,因為這是一個經驗公式-實驗的結果。 note! The unit θ (kg/m 2 h) and V (m/s) do not match because this is an empirical formula - the result of the experiment.
