hvac control system 中文意思是什麼
hvac control system
解釋
從事暖通空調自控系統-
In a conventional hvac control system, only air temperature and air humidity are controlled. as a result, the air - conditioned room is always not thermal comfortable enough, and the energy - conservation potentials is ignored either
傳統的空調控制系統以室內空氣的溫濕度為控制對象，結果是空調系統不僅不能提供滿足人體熱舒適需求的熱環境，並且常常忽略了系統的節能潛力。 -
In this programme, the database of many stored foods and experiential database are described by using production system, and, inexact reasoning is settled down with the method of fuzzy logic, finally, by separating the control knowledge and field knowledge, the design clue of expert in field is incarnated in the form of rules - base. the expert system created can simulate the thought and decision - making of expert in hvac field, and get the anticipative results
該程序中用產生式規則系統建立了冷藏食品信息庫和經驗數據庫，並運用模糊邏輯方法進行不精確推理，採用控制知識和領域知識分離控制流的方法，以規則庫的形式，體現了領域專家設計思路。該專家系統模擬專家進行符號推理及選取經驗數據，得到了較好的設計結果。 -
As we all know, occupants " thermal sense is mainly dependent on the six factors : inside air temperature, humidity, air velocity, mean radiant temperature, clothing and metabolism rate. the traditional hvac control system, neglecting other factors concerned with human comfort, only considering the inside air temperature and air humidity and indirectly impacting on occupants by the two parameters control, cannot satisfy the comfort requirement of occupants and is energy wasting as well
傳統的空調控制系統以室內空氣的溫濕度作為控制對象，而實際上影響人體熱舒適的因素不僅包括溫度與濕度，還有風速、平均輻射溫度、人體的衣著熱阻和人體的新陳代謝率，人體對環境的冷熱感受是這些因素綜合作用的結果，因此在很多時候系統並不能滿足人體對熱舒適的需要而且節能性較差。 -
The so - called comfort index - based control ( ci control ) is defined as the control of hvac system, which takes thermal comfort index as the control parameter
熱舒適指標控制（ ci控制）是以熱舒適指標為控制目標的hvac系統運行控制方式。 -
On the basis of the study on the thermal comfort theory and thermal comfort index, the so - called comfort index control ( ci control ) is defined as the control of hvac system, which takes thermal comfort index as the control parameter
於是人們在對傳統空調系統的反思以及對熱舒適理論和熱舒適指標的研究基礎上，提出了一種新型空調控制模式：熱舒適指標控制，又名舒適控制。 -
So if we convert the simple inside air temperature and humidity control into the thermal comfort index such as pmv as the control target in the hvac control system which evaluates the synthetic effects of th e thermal environment on human bodies, therefore, the hvac system control will change with the human sense, which will bring us a real " comfortable " hvac system
所謂舒適控制是以熱舒適指標作為hvac系統控制目標的運行控制方式。採用舒適控制后，空調系統的作用點從室內空氣轉移到了人體，使空調系統的控制隨著人體舒適感的變化而變化。 -
The main products include condensers, evaporators, radiators, heaters, oil - coolers, air - cooler, crf cooling modules, automobile hvac assembly, a c control panel assembly and automatic auto a c control system, widely applicable to mini vans, sedans, mpv, trucks and buses
目前主要產品有：汽車空調hvac系統a c控制面板總成冷凝器總成蒸發器總成散熱器總成加熱器總成自動汽車空調控制器總成等。 -
Chaoli adopts 5s, jit to realize lean manufacturing and set up perfect production control system and organization system. we import top - ranking manufacturing and testing equipments from japan, south korea, us such as evaporator with inner fin production line, condenser production line, hvac production line, heater production line, bus a c production line, automatic a c controller, so that the production capacity is 600, 000 units per year along with sub - assemblies and parts
超力高科從日本韓國美國等國家引進世界一流的生產設備和在線檢測設備與製造技術，擁有帶內翅片蒸發器芯體總成生產線冷凝器芯體總成生產線hvac總成生產線散熱器芯體生產線客車空調生產線自動空調控制器生產線，形成年產60萬套汽車空調系統的生產能力，可為用戶提供各種汽車空調系統分總成零部件。 -
In hvac system, the control is of complicacy, nonlinear, lagging and all kinds of interrupting factors, resulting in the traditional control method based on the precise mathematics model cannot reach the satisfactory dynamic - static effect
由於pmv指標的多變量、非線性特點以及hvac的復雜性，在實現上採用基於精確數學模型的經典控制理論有一定的難度，一般採用智能控制理論實現。
