夏季(ji)，利用保溫(wen)遮蔭(yin)幕(mu)遮擋(dang)陽(yang)光，阻止(zhi)多余的(de)(de)太陽(yang)輻射能(neng)(neng)進入溫(wen)室(shi)(shi)，既保證作(zuo)物(wu)(wu)能(neng)(neng)夠正常生長，又降低(di)(di)(di)室(shi)(shi)內(nei)能(neng)(neng)量聚(ju)集，從(cong)而降低(di)(di)(di)溫(wen)室(shi)(shi)內(nei)溫(wen)度(du)(du)，保護作(zuo)物(wu)(wu)免受強(qiang)光灼傷，并使(shi)室(shi)(shi)內(nei)溫(wen)度(du)(du)下降3-5℃；冬(dong)季(ji)，保溫(wen)遮蔭(yin)幕(mu)有反射室(shi)(shi)內(nei)紅外(wai)線，防止(zhi)其外(wai)逸(yi)的(de)(de)作(zuo)用，減少(shao)熱量散失，從(cong)而提高室(shi)(shi)內(nei)溫(wen)度(du)(du)，降低(di)(di)(di)能(neng)(neng)耗，降低(di)(di)(di)冬(dong)季(ji)運(yun)行成本。
