上班的第一件事，要打開窗戶還是先開冷氣呢？

根據(jù)哈佛等校的聯(lián)合研究《辦公室強化通風(fēng)系統(tǒng)的經(jīng)濟、環(huán)境與健康影響》，將辦公室的通風(fēng)率提高，對于員工的工作效率及健康皆有顯著提升的效果。

將通風(fēng)率提高兩倍后，員工的決策表現(xiàn)提高了8%，這相當(dāng)于每位員工每年可以多創(chuàng)造6500美元的產(chǎn)值。同時也明顯的提升了員工的工作效率。辦公室通風(fēng)除了為員工帶來新鮮空氣之外，也能減少辦公環(huán)境中揮發(fā)性有機化合物的濃度，經(jīng)由呼吸道傳染的病菌，因此，員工請病假的機率也降低了。

藉由開啟氣窗進行自然通風(fēng)的方式，相較于主動式的通風(fēng)設(shè)備來說成本低，又能帶來有效的換氣效果。

在韓國近畿道的一家電源供應(yīng)器公司，為了解決辦公室長年來通風(fēng)不佳的情況，將辦公室氣窗全面改裝為電動開窗器。

辦公室的窗戶區(qū)分出三個區(qū)段，上方為利用電動百葉窗作為氣窗，可排出室內(nèi)的熱空氣，下方的外推式窗戶，可引進涼爽的冷空氣，而中間的玻璃窗，則可讓室內(nèi)享有良好採光。

工程人員為電動開窗器加裝KST-A01系列電動推桿，利用電動推桿垂直升降的原理，帶動扇葉的開闔。

業(yè)主在電動開窗器內(nèi)側(cè)又加裝了通風(fēng)扇，可以更有效地將積聚在室內(nèi)上方的熱空氣抽出。

The first thing to do is to open the window or turn on the air conditioner first.

According to the joint study of the economic, environmental and health effects of the office intensifying ventilation system, the ventilation rate of the office is improved and the efficiency and health of the staff are significantly improved.

When the ventilation rate is increased by two times, employees' decision-making performance is increased by 8%, which means that each employee can create more than $6500 a year. At the same time, it also significantly improved the efficiency of employees. In addition to bringing fresh air to employees, office ventilation can also reduce the concentration of volatile organic compounds in the office environment, through respiratory infections, so the probability of employee sick leave is also reduced.

By means of natural ventilation by opening the air window, compared with the active ventilation equipment, it has low cost and can bring an effective ventilation effect.

In South Korea's Kinki Road, a DC power supply company has completely converted the office window into an electric window to solve the bad ventilation of the office for the long year.

The window area of the office is divided into three sections. The top is to use the electric shutters as the air window. The hot air in the room can be discharged. The extrapolated window below can introduce cool cold air, and the glass window in the middle can make the room enjoy good lighting.

The engineers installed the KST-A01 series electric push rod for the electric window opener, and used the principle of the vertical push and pull of the electric push rod to drive the opening and closing of the fan blades.

The owner also installed a fan inside the electric window opener, which can effectively extract the hot air accumulated above the room.
