Weak current College】 【various heating heating methods of comparison.

<br> 1. household-residential central air conditioning system <br> Heating type: "air-cooled and water-cooled". <br> Heating advantages: high quality, comfort, good. With fresh air system of the air-cooled ."more comfortable. Central air-conditioning system for a House is more free by developers. <br> Disadvantages: high cost of heating, each unit worth about tens of thousands of dollars, the cost per m2 paving as high as 500 Yuan, running .costs (mostly go tariff), used for hotels and luxury apartments, not suitable for most normal home use. <br> 2, electric heating film system <br> Heating type: most ceiling type, there are few parts of the laying of walls .and even under the floor <br> Heating advantages: low one-time investment, long service life. In a sealed, insulation, heat insulation of energy-saving House more energy efficient in use, operating costs should be between coal-fired and gas .. Each room its own thermostat. Although controversial, but the trend is definitely the power and heating. At the same time, Beijing has asked from October 2005, the new House to adopt the metering. <br> Heating disadvantages: on residential energy- .saving high-performance requirements. Not in ceiling nail holes, so that household decoration is restricted. <br> 3, free-standing gas (or electricity)-heating furnace <br> Heating type: natural gas, liquefied petroleum gas, gas, .electric energy, divided into different types of household heating furnace. <br> Heating advantages: can set heating time, household metering. Home is only preserved at low temperature of 4 degrees (antifreeze). A brand can also provide hot water at the same .time. Advanced than traditional heating, energy, security, can be installed on the wall and the corner of the room, the price of a few hundred dollars more in to 1000 Yuan. <br> Heating disadvantages: security, pollution (electric heating) ., and other risks, it is said, urban high-rise buildings are now used to control large suburban low density residential use more suitable. <br> 4. home use electric boiler <br> Heating type: divided into different imported brands. < .br> Heating advantages: small size, simple installation, operation facilities, heating and domestic hot water are also available. Comfort is high, suitable for larger low density residential buildings and villas. Most advanced is available in a wide range of slots, different temperature .preset function. <br> Heating disadvantages: frontloaded to larger, higher operating costs, the product is not suitable for the use of low electric regenerative heating in order to achieve the most energy saving effect. <br> 5. new energy storage-type .electric heater <br> Heating: electric heating furnace with a new type. <br> Heating advantages: clean, energy, and save money. At eleven o'clock automatically turn on the heat stored calories, while the following day beginning at seven will .automatically power off, the stored heat release at night, daytime electricity consumption. <br> Heating disadvantages: suitable for small size room, just started trying out, its product quality and technology needs further examination. <br> 6, digital module combination gas .roof boiler <br> Digital module combination gas roof-mounted boiler is in recent years, from overseas introduction of high-tech products. <br> But this product is still present security risks and environmental pollution problem also exists for the heating of water is .softened and boiler, pipeline cleaning, has now been banned to install in the building top floor. <br> 7, water source heat pump system <br> Use water-source heat pump system, you must set up the equipment and the underground compensation .backwater concentrated water circulation system. <br> In addition to the investment size is too large, will cover areas such as water resources, environmental protection, and other aspects of complex factors, implementation of difficult, in the water deficit zone, the prohibition of .the use of such equipment. <br> 8, radiant heating (water) <br> Low-temperature radiant floor heating, low temperature hot water as heating medium, by laying on the floor in the hot water floor heating, evenly to indoor radiant .heat, heat the room microclimate adjustment of energy-efficient heating system with thermal comfort, heat balance stability, energy, maintenance free, easy management, and other characteristics, market prices mainly depends on the pipe. <br> Heating type: by household- .gas heating furnace, municipal heat supply network, community boiler room, various ways to provide heat, as laying on the floor under the "alternative heat sink". <br> Heating advantages: surface temperature uniformity, gradually decreasing, at bottom, very clean .and comfort than most heating energy-saving impoliteness; increased 2% to 3% of the indoor area for decoration and display furniture; free thermostat. <br> Heating disadvantages: late in the process of using maintenance, temperature control is not accurate, on .-influential, forming a pipeline takes about 8 cm of space, is not conducive to the second decoration. <br> 9, radiant heating (heating cable) <br> Heating cable heating mode: in recent years is widely used in luxury villas, .relative to the plumbing has replaced by trend. The heat energy directly into electricity, thermal efficiency above 95%, to pass heat radiation, with comfortable, energy-saving, safety and environmental protection, etc. Heating cable for imported is preferred (European products .relatively good), its mature technology, reliable quality, the price is slightly higher. <br> Heating cable works: heating cable after power-on, the conductor temperature control at 40 ° ñ-60 degrees, through ground (24 ° - .28 degrees) as a cooling surface to radiation to pass above the ground, surface temperatures, to improve and maintain the room temperature. <br> Heating cable advantages: various indoor temperature, temperature can demand adjustment, each room can be controlled individually, save .energy, rising fast; no noise, no pollution; smart operation, low energy consumption, radiant heating, high thermal efficiency; do not take up any space for indoor and outdoor. High system reliability, security, and not easily damaged, no need to .maintain the service life of 50 years, one at a time, for life. <br> Heating cable shortcomings: not conducive to family second decoration. <br> <br> BR>.
