圖1是環境空氣壓力調解方法的流程圖。 Figure 1 is a flow chart of the ambient air pressure adjustment method.
圖2是具壓力調節之自然空調系統之內部示意圖。 Figure 2 is an internal schematic diagram of a natural air conditioning system with pressure regulation.
請參閱圖1為本發明進行環境空氣壓力調節的作業流程圖，主要可區分為初始設定階段、氣體流量調整階段以及氣壓維持階段，分別具體描述如下。 Please refer to FIG. 1 for a flowchart of the operation of adjusting ambient air pressure according to the present invention. It can be mainly divided into an initial setting stage, a gas flow adjustment stage and an air pressure maintenance stage, each of which is described in detail below.
於初始設定階段，包含步驟S1至S3。首先執行步驟S1設定為於建築物內部之目標環境的壓力環境相較於對比環境的氣壓為正壓或負壓，以醫院內部的負壓隔離病房為例，負壓隔離病房的氣壓通常比外部對比環境的氣壓低6至8帕斯卡(Pa)，負壓病房外的走道空間則相對為正壓。接著執行步驟S2，偵測目標環境的管制氣體濃度與實際氣壓值，以及對比環境的對比氣壓值，前述管制氣體通常為二氧化碳(CO2)或一氧化碳(CO)，因為過高的二氧化碳將會對人體健康造成危害，故為維持空氣品質的基本條件。因此，進入步驟S3，藉由決定最大進氣量來進行進氣，同時以一排氣量進行排氣，將管制氣體濃度降低至容許濃度值以下，確保目標環境內使用者的健康，此時目標環境的實際氣壓值通常偏高於步驟S1預設的正壓或負壓。 The initial setting phase includes steps S1 to S3. First, step S1 is performed to set the pressure environment of the target environment inside the building to be positive or negative compared to the air pressure of the comparison environment. Take the negative pressure isolation ward inside the hospital as an example. The air pressure in the negative pressure isolation ward is usually higher than that outside. Compared with the ambient air pressure, the air pressure is 6 to 8 Pascals (Pa) lower, and the corridor space outside the negative pressure ward has a relatively positive pressure. Then step S2 is performed to detect the controlled gas concentration and actual air pressure value of the target environment, as well as the comparative air pressure value of the comparison environment. The aforementioned controlled gas is usually carbon dioxide (CO2) or carbon monoxide (CO), because too high carbon dioxide will be harmful to the human body. It causes harm to health and is therefore a basic condition for maintaining air quality. Therefore, step S3 is entered, by determining the maximum air intake volume to carry out air intake, and at the same time exhausting air at a certain exhaust volume, reducing the concentration of the controlled gas below the allowable concentration value to ensure the health of users in the target environment. At this time The actual air pressure value of the target environment is usually higher than the positive pressure or negative pressure preset in step S1.
為了達到所設定的正壓或負壓，兼顧節省能源的目的，於氣體流量調整階段執行步驟S4至S7。首先進行步驟S4來減少進氣量，同時維持排氣量，使得目標環境內的實際氣壓值下降，且避免管制氣體濃度高於容許濃度值，接著在步驟S5來偵測與比較目標環境的實際氣壓值與對比氣壓值是否形成設定的正壓或負壓，且兩者氣壓差的絕對值小於一壓力門檻值時(即目標環境的實際氣壓值開始趨近於形成所設定正壓或負壓的氣壓值，設定為正壓時目標環境的實際氣壓值大於對比環境的氣壓值，設定為負壓時目標環境的實際氣壓值小於對比環境的氣壓值)，進入步驟S6來減少排氣量並維持進氣量，使得目標環境的實際氣壓值略為回升，再執行步驟S7偵測並比較目標環境的管制氣體濃度是否低於容許濃度值，且管制氣體濃度趨近於容許濃度值(即兩者的差值小於一濃度門檻值)，若比對結果為否，則回到步驟S4來減少進氣量，反之 則結束氣體流量調整階段，進入步驟S8的氣壓維持階段，維持調整後的進氣量與排氣量，維持目標環境的實際氣壓值直到結束。 In order to achieve the set positive pressure or negative pressure while taking into account the purpose of saving energy, steps S4 to S7 are performed in the gas flow adjustment stage. First, step S4 is performed to reduce the air intake volume while maintaining the exhaust volume, so that the actual air pressure value in the target environment decreases and prevents the controlled gas concentration from being higher than the allowable concentration value. Then, in step S5, the actual air pressure in the target environment is detected and compared. Whether the air pressure value and the comparison air pressure value form a set positive pressure or negative pressure, and the absolute value of the difference between the two air pressures is less than a pressure threshold (that is, the actual air pressure value of the target environment begins to approach the set positive pressure or negative pressure (when set to positive pressure, the actual air pressure value of the target environment is greater than the air pressure value of the comparison environment; when set to negative pressure, the actual air pressure value of the target environment is less than the air pressure value of the comparison environment), enter step S6 to reduce the exhaust volume and Maintain the air intake volume so that the actual air pressure value of the target environment rises slightly, and then perform step S7 to detect and compare whether the controlled gas concentration of the target environment is lower than the allowable concentration value, and the controlled gas concentration approaches the allowable concentration value (i.e. both The difference is less than a concentration threshold), if the comparison result is no, return to step S4 to reduce the intake air volume, otherwise Then the gas flow adjustment phase ends, and the air pressure maintenance phase of step S8 is entered to maintain the adjusted intake air volume and exhaust volume, and maintain the actual air pressure value of the target environment until the end.

在本實施例中，第一熱交換器32安裝於排風道20鄰近第二水熱交換器45，第二熱交換器33安裝於進風道10鄰近第一水熱交換器44，使得預冷水熱交換器41、水蒸發器42、第二水熱交換器45、第一熱交換器32沿著排風道20的一出風方向依序設置。 In this embodiment, the first heat exchanger 32 is installed in the exhaust duct 20 adjacent to the second water heat exchanger 45, and the second heat exchanger 33 is installed in the air inlet duct 10 adjacent to the first water heat exchanger 44, so that the preset The cold water heat exchanger 41 , the water evaporator 42 , the second water heat exchanger 45 , and the first heat exchanger 32 are arranged in sequence along an air outlet direction of the exhaust duct 20 .

藉由上述組件形成的能量轉換裝置具有空調冷氣供應，可以依據作用空間的需求調整空調能量。例如，在室內溫度值大於冷氣供應設定值時，室內空氣自排風道20排出，室內空氣會先經過排風道20的入風口通過濾網21過濾，流經預冷水熱交換器41進行熱交換，預冷水熱交換器41會對空氣產生預冷作用，獲得第一次的降溫效果。預冷水熱交換器41內的水從出水端至高處的噴水頭，並噴灑於水蒸發器42，經過水蒸發器42的過濾、蒸發作用，會與通過之空氣產生水蒸發吸熱效應，以轉移空氣中的顯熱，使空氣產生第二次的降溫，同時水蒸發器42所送出之水也獲得降溫，再藉由水泵46傳送至第一水熱交換器44。而通過水蒸發器42的空氣，在流經第二水熱交換器45時，可以將第一水熱交換器44所傳來之熱移除，在水蒸發器42所得到的水分，將可在第一熱交換器32再次進行濕熱的轉換，因此，使得排出於室外的空氣溫度，係遠較傳統直接由冷凝氣排放於室外之空氣溫度為低，可降低廢熱排放對環境之熱污染。 The energy conversion device formed by the above components has an air-conditioning cold air supply and can adjust the air-conditioning energy according to the needs of the working space. For example, when the indoor temperature is greater than the air-conditioning supply set value, the indoor air is discharged from the exhaust duct 20. The indoor air will first pass through the air inlet of the exhaust duct 20, be filtered by the filter 21, and then flow through the pre-cooled water heat exchanger 41 for heating. Exchange, the pre-cooling water heat exchanger 41 will produce a pre-cooling effect on the air and obtain the first cooling effect. The water in the pre-cooled water heat exchanger 41 flows from the water outlet end to the water spray head at the top, and is sprayed on the water evaporator 42. After the filtration and evaporation of the water evaporator 42, it will produce a water evaporation and endothermic effect with the passing air to transfer The sensible heat in the air causes the air to cool down a second time. At the same time, the water sent out by the water evaporator 42 is also cooled down, and is then sent to the first water heat exchanger 44 through the water pump 46 . When the air passing through the water evaporator 42 flows through the second water heat exchanger 45, the heat transferred from the first water heat exchanger 44 can be removed, and the moisture obtained in the water evaporator 42 can be Moisture and heat are converted again in the first heat exchanger 32, so that the temperature of the air discharged to the outside is much lower than that of the traditional air discharged directly from the condensed air to the outside, which can reduce the thermal pollution of the waste heat discharge to the environment.
此外，自水蒸發器42所送出之循環水，藉由水泵46傳輸至第一水熱交換器44，而第二水熱交換器45出水端的水溫已接近室內側空氣的露點溫度，因此，當自進風道10進入之空氣流經第一水熱交換器44，也因循環水已接近室內側空氣的露點溫度，使空氣先預冷降溫，而當空氣通過第二熱交換器33時，主動式能量轉換機組的熱負荷已降低，故可增強其運轉效率，以供應室內所需之低溫且新鮮的空氣，並達到節能之目的。 In addition, the circulating water sent from the water evaporator 42 is transmitted to the first water heat exchanger 44 through the water pump 46, and the water temperature at the outlet end of the second water heat exchanger 45 is close to the dew point temperature of the indoor air. Therefore, When the air entering from the air inlet duct 10 flows through the first water heat exchanger 44, because the circulating water is close to the dew point temperature of the indoor air, the air is pre-cooled and cooled first. When the air passes through the second heat exchanger 33 , the heat load of the active energy conversion unit has been reduced, so its operating efficiency can be enhanced to supply the low-temperature and fresh air required indoors and achieve energy saving.
當目標環境設定為正壓而使得進氣量較大時，主動式能量轉換機組也會對進風道的氣體進行升溫或降溫，以達到使用者所設定的溫度值。 When the target environment is set to positive pressure and the air intake volume is large, the active energy conversion unit will also heat or cool the gas in the air inlet duct to reach the temperature value set by the user.
