【正文】 e parison of the lack of parability of operating expenses: first, the room where the floors, the room toward, wall insulation status, size, and whether to adopt the double glazing insulating glass, etc., causing the house insulation, thermal conditions vary widely, such as single house multifaceted wall direct contact with the outside world more heat, if the insulation does not do well, the room to achieve the same temperature, the heat may be required for the multiply. Second, each family used to working with different families need the fort of the temperature difference between 2 ~ 5 ℃ , while others sooner or later, the family used two halfhour window for natural ventilation, which are the impact on the running costs. Floor heating method using radiation heating, heating, consistent with physiological demand curve, an indoor set temperature even lower than the convective heating and 2 ~ 5 ℃ , also enable people to have the same warm feeling, while floor heating using lowtemperature heat source, temperature transmission greatly reduced heat loss, heat efficient than convection heating, greatly improved, which makes the system operating costs reduced by 20 ~ 30%. If selected, the control system used properly, can not only improve room fort, but also make the system operating costs be reduced to 40% or even more. 4, the plot is the central heating can be installed in heating system? Heating or central airconditioning central heating in residential hot water supply temperature of 60 90 ℃ , if they are directly connect to the regular (PERT) temperature of the floor heating 無錫職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說明書（論文） 7 system is clearly too high, not only because of high surface temperatures caused by the human body disfort, but also reduces the ground heating system life. To warm the pany imported mixed center in the central heatinghomeside bypass to connect the establishment of mixedfloor heating system, floor heating system to warm the water temperature was controlled at the required 30 50 ℃ temperature, or using high temperature (95 ℃ ) ground heating pipe (PEXb, Pb), you can use the floor heating system. 地板輻射采暖的運(yùn)行費(fèi)用怎么樣？ 地板輻射采暖的運(yùn)行費(fèi)用通?？梢员葘α鞴┡到y(tǒng)降低 20%40%。 控制系統(tǒng)的 配備取決于用戶想達(dá)到的舒適度和性價比，為達(dá)到不同的控制性能，選取的系統(tǒng)價格可能相差數(shù)十倍，現(xiàn)在不少地暖隊(duì)伍沒有設(shè)計(jì)能力，不是沒有控制系統(tǒng)，就是盲目選取某一單項(xiàng)高端產(chǎn)品，使系統(tǒng)不匹配，達(dá)不到應(yīng)獲得的控制效果。 地下隱蔽結(jié)構(gòu)中的管材、保溫材料及各種輔材，選材不同價格相差很大，相同的選材，價格差別一般不會很大，過低的價格只能意味著選取了偽劣甚至不能達(dá)到基本性能要求的材料。 PEX 無論在國內(nèi)、國外因其性能穩(wěn)定、價格適中被廣泛應(yīng)用， PEXb 是地暖系統(tǒng) 中應(yīng)用最早也是最廣，最為成熟的地暖管材，其中綜合性能 pexb 為優(yōu)，地暖管材的生產(chǎn)符合標(biāo)準(zhǔn)，設(shè)計(jì)和使用在正常的產(chǎn)品標(biāo)準(zhǔn)范圍內(nèi)，實(shí)際壽命都超過 50 年，可以認(rèn)為：地暖系統(tǒng)基本與建筑物壽命相當(dāng)。 現(xiàn)在用于地暖系統(tǒng)的管材一般為 PERT、 PEX（ a、 b、 c）、Pb 管材等， PERT 的使用在 65 度以下，工作壓力不超過 ， PEX、 Pb 管材的無錫職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說明書（論文） 6 使用工況（耐壓、耐高溫 )都優(yōu)于 PERT，長期工作溫度可在 95 度至零 70 度范圍內(nèi)。行業(yè)專家提示，要想享受沒有后顧之憂的地板采暖，一定要 選擇專業(yè)正規(guī)，有一定規(guī)模資質(zhì)的地暖公司施工，而不要以圖一時便宜，花了不必要的 “學(xué)費(fèi) ”。部分地暖公司不是以長遠(yuǎn)眼光經(jīng)營市場，而是能撈一把就撈一把的思想，致使很多用戶深受其苦，不是施工半截地暖公司不知去向，就是施工完畢供暖不熱不暢，一方面由于地暖公司自身問題造成，另一方面也反映出很多用戶圖一時便宜造成。地暖系統(tǒng)設(shè)計(jì)是否合理， 地暖管 材、發(fā)熱電纜鋪裝位置、環(huán)路間隔是否合理，施工質(zhì)量是影響地暖使用功效的主要原因，兩者均不能忽視，才能高枕無憂。 ⑤ 運(yùn)行費(fèi)用低：較其它供暖設(shè)備節(jié)能約 20%,可充分利用低 溫?zé)崴Y源或利用電價政策 ,降低運(yùn)行費(fèi)用。 ③ 高效節(jié)能：輻射供暖方式較對流供暖方式熱效率高，熱量集中在人體受益的高度內(nèi)；傳送過程中熱量損失??；低溫地面輻射供暖可實(shí)行分層、分戶、分室控制，用戶可根據(jù)情況進(jìn)行調(diào)控，有效節(jié)約能源。 lowtemperature floor radiant heating may apply stratified, household, subroom control, users can Depending on the situation to control, effective energy conservation. ④ thermal stability: the ground floor and concrete floor heating on the ground build heat, thermal stability, in the intermittent heating conditions, the indoor temperature change is slow. ⑤ operating costs low: energyefficient than other heating equipment, about 20%, which may take advantage of lowtemperature hot water or the use of price policy to reduce operating costs. 四、地暖的優(yōu)點(diǎn) ① 舒適、衛(wèi)生、保健：地面輻射供暖是最舒適的供暖方式，室內(nèi)地表溫度均勻，室溫由下而上逐漸遞減，給人以腳溫頭涼的良好感覺；不易造成污濁空氣對流，室內(nèi)空氣潔凈；改善血液循環(huán)，促進(jìn)新陳代謝。 improve blood circulation, promote metabolism. ② to save space, beautify the living room: Interior canceled the radiator and the branch pipes, the increased use of space, to facilitate renovation and decoration of our homes to reduce health corners. ③ efficient energysaving: radiation heating, convection heating a relatively high thermal efficiency, heat concentrated in the human body within a high degree of benefit。 Fourth, to warm the advantages of ① fort, health, health care: ground radiant heating is the most fortable way of heating, indoor surface temperature uniformity at room temperature, gradually decreasing from the bottom up, giving people a good cold feet warm feeling of the first。 無錫職業(yè)技術(shù)學(xué)院畢業(yè)設(shè)計(jì)說明書（論文） 3 低溫輻射 電熱膜 是一種通電后能發(fā)熱的半透明聚酯薄膜，由可導(dǎo)電的特制油墨、金屬載流條經(jīng)加工、熱壓在絕 緣聚酯薄膜間制成。 發(fā)熱電纜地面輻射供暖是以低溫發(fā)熱電纜為熱源，加熱地板，通過地面以輻射和對流的傳熱方式向室內(nèi)供熱的供暖方式。 Third, to warm the classification of Floor radiant heating in accordance with the different heating methods can be divided into plumbing and electrical heating, but there are electric heating heating cable heating and electric heating film divided. Plumbing the low temperature hot water floor radiant heating is a temperature no higher than 60 ℃ hot water for hot coal, circulating in the heating pipe, heating thefloor, through the ground to radiation and convection heat transfer means of heating to the indoor heat. Heating cable floor radiant heating is a lowtemperature heating cable as heat source, heating the floor, through the ground to radiation and convection heat transfer means heating to indoor heating. Common heating cable is divided into singlecore cables and twincore cables. Lowtemperature radiation heating after the film is a kind of power can heat translucent polyester film, made from special conductive ink, the metal carrier, as amended, processing, and hot in the rooms made of polyester film insulation. Work with carbonbased ink for heat body heat in the form of radiation into space, so that the human body to be warm. 三、地暖的分類 地 面輻射供暖按照供熱方式的不同主要分為 水暖 和電暖，而電暖又有 發(fā)熱電纜 采
