Since the PV 531, the northern clean heating policy has been heavily reformed to use clean energy for heating. Many places are introducing photovoltaic + heating, air energy heat pump heating.
With the development of science and technology, great changes have taken place in all aspects of people's lives. In terms of the way of heating, there have been earth-shaking changes. For example, it is very popular nowadays for household photovoltaic heating. So what are the advantages of home PV heating?
What are the advantages of home PV heating:
1, the use of the whole year: can achieve winter photovoltaic heating (also available throughout the year) and year-round bath use. This is a revolutionary advancement in photovoltaic water heaters and a major technological breakthrough in photovoltaic applications;
2. Low investment and low cost: The one-time investment of PV heating system is obviously lower than the initial investment of central heating, fuel coal-fired boiler, etc., and no approval is required. The daily operation cost is much lower than that of central heating under the same heating condition. The fuel-fired gas-fired electric boiler is even cheaper than the earth heating and air-conditioning. It can also realize the whole-year bathing function, which solves the problem that the system is idle in the spring, summer and autumn, and the equipment depreciation is accelerated.
3, 24 hours application: How many days to use according to the temperature each year, do not have to worry about the high cost of using gas boilers or air conditioners, and can only open for 2 hours a day, other times hard support.
4, intelligent control: the perfect combination of photovoltaic and electricity, dynamic intelligent operation mode, daily expenses are reduced to a minimum. The photovoltaic heating bath system consists of a high-temperature photovoltaic heating system on the roof and an indoor computer intelligent control system.
5, the operation setting is simple: in a lot of areas in sunny weather, 24 hours a day to use PV heating. If you feel that the room needs a higher temperature on a rainy day or at night, you can use electricity to replenish it. The application of photovoltaic broadband technology and electric compensation frequency conversion technology enables photovoltaics to use up to 60%-95% of the energy in the whole system.
6, safe and clean and pollution-free: easy to operate, easy for the elderly and children to use. Avoid the diseases caused by the cold, and create a new life that is healthy, comfortable and warm.
In recent years, with the continuous maturity of technology and technology, the social and economic consumption environment is also changing. With the continuous expansion of heating areas, most air energy manufacturers have developed their own heat pump heating products, from south to north, from From home to commercial office space, the use of air for heating is becoming a trend.
The air heating system mainly uses an air source heat pump as a heating source to complete the heating of the room by combining with the heating end. The principle of the air source heat pump is to use the inverse Carnot principle to absorb a large amount of low-temperature heat energy in the air with little electric energy, and to become high-temperature heat energy through compression of the compressor, which is an energy-saving and efficient heat pump technology. When the air source heat pump is in operation, the evaporator absorbs heat from the ambient heat energy in the air to evaporate the heat transfer medium. The pressure and temperature of the working medium vapor are compressed by the compressor, and the high temperature vapor is permanently bonded to the outer surface of the storage tank. When the annular tube condenser is condensed into a liquid, the released heat is transferred to the water in the air source heat pump storage tank, and the condensed heat transfer medium is returned to the evaporator through the expansion valve, and then evaporated, and thus reciprocated.
Introducing the principle of the air heating system, then let's talk about the advantages of the air heating system?
Advantages of air heating:
1. Clean and comfortable: the air can warm up the heating of the machine from the foot, so that the temperature of the whole indoor space is evenly distributed, there is no hot air feeling, which is beneficial to the body to maintain moisture, and has positive effects on rheumatism and asthma;
2, high efficiency and energy saving: 35-60 °C for air-heating machine (85 °C for convection radiator), the heat is concentrated in the human body's benefit height (below 2 meters), 80% energy saving compared with traditional electric heating method;
3, save space: air can warm the machine to lay water pipes under the floor, save space, and can be used with different decorative styles;
4, long-term durability: the air can be used to warm the machine buried in the underground, no scaling, no corrosion, no damage, the service life and the building synchronization. Compared to traditional central air conditioning and radiator heating, maintenance and replacement costs are eliminated.
5, safe and reliable: the room with heating in winter is better airtight, if you use gas heating products, there will be a risk of carbon monoxide poisoning, and air heat pump heating does not need to worry about such problems.
6, a wide range of uses: products can be used in factories, hotels, schools, hospitals, beauty salons, bathing centers, villas and other home use.
The price of raw natural gas heating gas is rising. The price of natural gas a year ago cannot be compared with the current price. However, natural gas prices will be more expensive in the future, and the trend will only increase. Facing the current situation of rising natural gas prices and mandatory requirements for building energy conservation, and because air energy heating is more than 30% more energy efficient than traditional burning natural gas heating, it has become a trend of heating use.
