Home heating method
Free-standing gas (or electric) heating furnace
Type: It is divided into different types of household heating furnaces by using natural gas, liquefied petroleum gas, gas and electricity as energy sources.
Advantages: You can set the heating time by yourself and measure by household. When no one is in the house, it is only necessary to keep the low temperature operation of about 4 degrees (antifreeze effect). Some brands can also provide domestic hot water. It is more advanced, energy-saving and safer than traditional heating. It can be installed on the wall and in the corner of the room. The price is about several hundred yuan to 1,000 yuan.
Disadvantages: There are hidden dangers such as safety and pollution (except electric heating). It is said that urban high-rise residential buildings are now controlled for large-scale use, and low-density residential use in suburbs is more suitable.
Household household central air conditioning heating system
Type: There are two types of "air-cooled" and "water-cooled".
Advantages: high grade, good shape and high comfort. The "air-cooled" with fresh air system is more comfortable. The central air-conditioning system is often given free of charge by the developer when buying a house.
Disadvantages: high cost, each set of units worth about tens of thousands of yuan, the cost per square meter pavement is as high as 500 yuan, high operating costs (most of the electricity costs), mostly used in restaurants and high-end apartments, not suitable for most ordinary households.
Radiant floor heating
Type: The heat source can be provided by various methods such as household gas heating stove, municipal heat pipe network, and community boiler room, as an "alternative radiator" buried under the floor.
Advantages: uniform ground temperature, room temperature gradually decreasing from bottom to top, high comfort, very clean, more than 20% energy saving than most heating methods; can increase 2% to 3% indoor use area, easy to decorate and pendulum Put furniture; adjust the temperature at will.
Disadvantages: Inconvenient for secondary decoration; maintenance troubles, to choose high-pressure environmental protection pipe with pressure, temperature, corrosion resistance, thermal stability, good impact on the layer height, paving pipeline needs to occupy about 8 cm of space; Carpeting will affect the heating effect; for a long time, the furniture may be deformed.
Electric film heating system
Type: Most are ceiling-type, and a small part is laid in the wall or even under the floor.
Advantages: less one-time investment and long service life. It is more energy-efficient to use in energy-saving houses with strong sealing, heat preservation and heat insulation. The operating cost should be between coal and gas. Each room can be tempered by itself. Despite the controversy, the adoption of electric heating is definitely a trend. At the same time, Beijing has requested that metered heating be used for new commercial housing from October 2005.
Disadvantages: High energy efficiency requirements for residential buildings. It is not possible to drill holes and nails in the ceiling, which limits the residents' decoration.
Household electric boiler
Type: Divided into domestic and imported brands.
Advantages: small footprint, simple installation, convenient operation, and can provide domestic hot water while heating. High comfort for low-density homes and villas with larger areas. The most advanced is the multi-time, different temperature control preset function.
Disadvantages: The initial investment is large and the operating cost is high. The product is not suitable for low-temperature electric heat storage heating to achieve the most energy-saving effect.
New energy storage heater
Type: A new type of electric heating stove.
Advantages: clean, energy saving, and save money. It will automatically turn on at 11 o'clock in the evening, store heat at the same time of heat dissipation, and automatically power off at 7 o'clock the next day. It will release the heat stored at night and consume no electricity during the day.
Disadvantages: It is suitable for rooms with small area. At the beginning of trial use, its product quality and technology need to be further tested.
Digital module combination gas roof boiler
The digital module combination gas roof complete boiler is a high-tech product imported from abroad in recent years.
However, this product still has safety hazards and environmental pollution problems. There are also softening treatments for heating water and descaling of boilers and pipes. It has been banned from being installed on the top floor of buildings.
Water source heat pump air conditioning system
With the water source heat pump air conditioning system, underground compensation and return water equipment and centralized circulating water system must be installed.
In addition to the increase in investment scale, it will involve complex factors such as water resources and environmental protection. It is difficult to implement. In the water-deficient areas, the use of such equipment is prohibited.
Of course, there should also be a heat source and a common radiator heating system that can be provided by various types of gas heating stoves, municipal heat pipe networks, and community boiler rooms. The far-infrared heat-radiating plate with a surface temperature of 70 to 90 degrees Celsius and an intelligent far-infrared heat-radiating heating system with a surface temperature of 80 to 120 degrees and a light-heat-conducting wire as a heating element.
1. Use Surface Mount System to install electron component. High quality stable and more quality consistency.
2. Pass germany TUV testing, have EMC and LVD certificate.
3. The AC input power voltage is made between 85V to 240V. So it could select AC input voltage automatically. You could work in AC USA 110V or AC europe 220-240V.
4. CEL: Cellulose electrode is special electrode to lay big pipe on oil and chemical industry, natural gas, electric power, civil pipeline of oil, gas, water. They need high ilder voltage (more than 90V). This machine could do
TIG Welding Machine, MIG Welding Machine, MMA Welding Machine
