A. The temperature of the household wall-mounted oil-gas boiler (wall-mounted boiler of Dedijia) can be adjusted freely. In Huilongguan Community, Pearl River International City, Wanhe and Shi Jia, household wall-mounted gas heaters are mainly used for heating in winter. According to the relevant person in charge of Zhujiang International City, the household wall-mounted gas heating of this project is intelligent. After installing the indoor thermostat, you can adjust the temperature of different rooms at will. For example, if you stay in the bedroom and are on duty in other rooms, you can only raise the temperature in the bedroom. When there is no one at home, just drop the temperature to the duty temperature of no one at home to ensure that the machine and circulating water do not freeze; Before you go home from work, you can start it through the intelligent module, and you can feel the warmth of home immediately after you get home. Burying the heating pipe under the composite floor leaves only the radiator on the surface, which not only cools the gas to dissipate heat, but also warms the floor, saving the area and improving the overall indoor thermal effect. At the same time, we interviewed Ms. Ren who has lived in Huilongguan for more than three years on the use effect of this heating method. From her experience, in the first year of use, there may be air in the pipeline, which is not easy to ignite and has a lot of noise, so the heating situation is not very good. However, it has been basically stable in the past two years, and the residential properties regularly check the heating stoves before heating, ensuring the safety of residents' heating in winter. Principle: In this way, a wall-hung boiler is generally installed in the kitchen or balcony, and natural gas is burned through the wall-hung boiler to achieve the purpose of heating. Indoor pipes and radiators are connected with the wall-hung boiler, which can generally realize double supply of heating and hot water at the same time. Applicable residence: Advantages of low-density residence: 1. The heating time can be set freely and turned on at any time. 2. The temperature of each room can be adjusted at will within a certain range. Some heaters can provide domestic hot water at the same time. Disadvantages: 1 The service life of the heating furnace is about 15 years, and the renewal cost shall be borne by the owner. 2. When there is no one at home, it is necessary to maintain a low temperature of about 4 degrees Celsius (antifreeze effect). 3. The heat pump is often started, with flame burning, loud noise and some air pollution problems. Cost: Take Miss Ren's 87m2 room as an example. When the set temperature of the furnace is 60 degrees Celsius and the room temperature is about 20 degrees Celsius, the average gas consumption is 1 hour 1 word. Every word of gas is calculated by 2 yuan, and it is used for 15 hours every day, which is about 3600 yuan in 30 yuan. In a heating season. Tip: 1. Buy enough natural gas and plug it in. 2. Check that the heating and water supply pressure is about 1.2 bar within the specified range, and check the pressure gauge (not too high, the water heating pressure will increase to about 2.0bar). 3. Open the natural gas valve and heating inlet and outlet valves on the wall-hung boiler, and adjust the heating temperature to, for example, 6. The boiler should ignite normally and feel the hot water output. 4. Open the vent valve on the radiator. As the water temperature rises, there may be a squeak. Don't be nervous, because the gas in the pipe is squeezed out and the water can't come out. 5. After one hour, make sure that each group and each piece of heater is hot from top to bottom, that is, there is no residual air, so you can close the bleeder valve. 6. The next day, when the furnace is not cold, check again whether the water supply pressure is around 1.2 bar. Replenish water when the pressure drops, and drain water when the pressure is too high. B. radiant floor heating: the room temperature gradually decreases from bottom to top. Principle: Low-temperature radiant floor heating is to heat the floor to the surface temperature of 18 to 32 degrees Celsius through a heating pipe buried under the floor, and radiate heat evenly to the room to achieve the heating effect. At the same time, heat sources can be provided in different ways, such as domestic gas heating stoves, municipal heating pipe networks and residential boiler rooms. Applicable residence: finely decorated apartment (Shuguang Garden, Beautiful Garden, Vanke Xingyuan, Dong Run Fengjing) Advantages: 1 The ground temperature is uniform, the room temperature gradually decreases from bottom to top, and the comfort is high. 2. The air convection is weakened and the air cleanliness is good. 3. Compared with other heating methods, it is more energy-saving, and the energy-saving range is about 10% to 20%. 4. Conducive to indoor decoration, increasing indoor usable area by 2% ~ 3%. 5. Conducive to sound insulation and reducing floor impact sound. Disadvantages: 1 It occupies a floor height of about 8 cm. 2. When the ground is renovated for the second time, it is easy to damage underground pipelines. 3. It is troublesome to crack the wooden floor, and it is best to use floor tiles or composite floors. 4. The set temperature should not be too high, otherwise the service life of the pipeline will be greatly reduced. 5. Because of the need of waterproof, it is inconvenient to lay the bathroom, so it is necessary to use electric heating. Operating cost: about 14 yuan 18℃ per square meter in a heating season. Tip: When using radiant floor heating, it is best to lay marble or tile floor during decoration. At the same time, it is best to leave a certain distance of grooves in the floor decoration to facilitate heating. C. Household electric boiler: principle of free temperature adjustment: heating by electric energy. Applicable residence: advantages of villa: 1. Small floor space, simple installation and convenient operation. 2. Heating can also provide domestic hot water. 3. High comfort, suitable for low-density houses and villas with large area. 4. The most advanced feature is that it has multiple time periods and different temperature control preset functions. Disadvantages: 1 The initial investment is large and the operating cost is high. This product is not suitable for low-valley electric heat storage to achieve the most energy-saving effect. Cost: Take a room of 100 square meter as an example, the basic operating cost of a heating season is 3,000-5,000 yuan. D. Electric heating film: environmental protection and fashion principle: electricity is used as energy, and it is a pure resistance heater made of special conductive ink printed between two layers of polyester film, with an independent temperature control device. The heater adopts low-temperature radiant electric heating film, most of which are suspended ceiling type, and a few of them are laid in the wall or even under the floor. It has the characteristics of adjustable constant temperature, economic comfort, environmental protection, long service life and maintenance-free. Applicable residence: finely decorated apartment (Yijing Jiayuan, Vanke Xingyuan) Advantages: 1 There is no radiator in the room, and the usable area of the room can be increased by 2% to 3%, which is convenient for decoration and furniture placement. 2. Generally, maintenance is not required. 3. It belongs to clean energy and has no pollution. The room temperature can be adjusted by thermostat. 5. There is no thermal sensation of traditional heating, and the temperature is uniform. Disadvantages: 1 The electrothermal film generates heat slowly, and it usually takes 1 to 1.5 hours to reach 18 degrees Celsius. 2. The installation of the system should be synchronized with the decoration, and nails and holes cannot be nailed on the ceiling. 3. It is not advisable to use residential areas with poor and unstable power supply or high electricity charges. Cost: Take Mr. Cai's home area in Vanke Xingyuan as an example. If the daily electricity consumption is 80 to 100 kwh, the cost of a heating season is between 1920 yuan and 2400 yuan. Residents' comments (excerpted from "Focus Network" Flower Market Jujube Garden Owners Forum): 1. Listen to me, install electric heating film. I didn't look at the decoration of others' homes, and I don't know anything, but now the effect is good. It will get hot in a few minutes. Hehe, it feels good. It's true that the house will be shorter, which saves trouble. (Dragon 75) 2. Through the experience of last winter, geothermal effect is better than electric heating film, but it is expensive. Last year, I heard that geothermal energy has a service life of about 30 years, which is longer than electric heating film and has a good use effect. (Always working overtime) 3. Reminder: Take a look at the electricity meter. Even if heating and domestic electricity are separated now, excessive electricity consumption will still trip. 124mao E, domestic central air conditioning system: comfort and safety principle: municipal electricity or natural gas is used to provide heat source heating through the air outlet. Applicable residence: finely decorated apartment Advantages: 1 High grade, good appearance and high comfort. 2. "Air cooling" with fresh air system is more comfortable. 3. The temperature and time can be preset. 4. High comfort, suitable for low-density houses and villas with large area. Disadvantages: 1 The initial investment is large and the operating cost is high. 2. You can't enjoy the national preferential policies for low power consumption. Cost: 24 yuan /m2 in heating season. F. Electric heating: It is understood that this year, 6,543,800 square meters of buildings and about 200,000 households in this city have used electric heating, an increase of more than 300,000 square meters over last year, mainly concentrated in historical and cultural protection areas in Dongcheng District and Xicheng District. With the promotion of electric heating by Beijing municipal government, a series of preferential policies for electricity consumption have been introduced, and the advantages of land saving, environmental protection and energy saving of household heating have become prominent. At present, household electric boilers, low-temperature radiant electric heating films, geothermal cable heating, electric heaters, thermal superconducting fast heaters are widely used, and these products are expected to become the new favorites of new houses. However, according to the reporter's interview, there are still some problems in electric heating, and the development situation is not optimistic. From the specific situation of West Ring Garden, Huashi Zaoyuan and other residential areas, the problems reflected by users on electric heating are concentrated in: 1. High cost. Due to the construction quality and the batch occupancy of newly-built commercial housing, the heating cost of consumers is generally high. In Mr. Luo's 90-square-meter house, the indoor temperature has been kept at 18℃, and the electricity consumption in the first heating season reached 8000 degrees. After two years, the electricity consumption has decreased a little, but it is still around 35 yuan per square meter. 2. The insulation lacks corresponding supporting facilities. Experts believe that some related insulation materials such as building quality (mainly insulation layer, door and window quality), energy saving and capacitance (related to electric heating) are not up to standard; Low occupancy rate, lack of insulation interlayer on four walls, too high floors and too many windows are all reasons for low indoor temperature. Failure is not easy to solve. According to Mr. Gao of Zhongyuan Property Company, the electric heater itself is a kind of equipment with high precision, so repair rate has also been improved. Because some electric heating uses shed roof or underground pipeline, it is difficult to maintain, and the normal life of residents in winter is affected accordingly. According to incomplete statistics, judging from the newly opened heating systems in the property market this year, most of them still adopt traditional central heating methods, and the proportion of electric heating is not large. G. central heating: the main principle of urban heating: using urban heating network, regional heating network or large-scale central heating as heat source may still be the main way of urban residential heating at present and in the future. Applicable residence: ordinary residence (most residential areas in the city) Advantages: 1 The technology is relatively mature, safe and reliable, easy to use and cheap. 2. Heating 24 hours a day. Disadvantages: 1 The heating time and temperature cannot be controlled by themselves, and the vertical fins are unsightly, occupying space and affecting the decoration effect. 2. There is no heat source before and after the heating period. The radiator is used for heating. Generally, the outlet water temperature is above 70 degrees Celsius, but when the temperature reaches 80 degrees Celsius, a cloud of dust will be generated, which will cover the wall above the radiator with dust. Cost: Take 100 square meter room as an example. According to the regulations of Beijing Municipality, the operation and payment fee of gas heating is 24 yuan/m2. A heating season needs to pay 2400 yuan. Source: Jiangsu Tianhe heating and cooling equipment engineering technology co., ltd.
