Haining Xianke New Materials Technology Co., Ltd., to undertake large and medium-sized enterprises in Shanghai solar hot water project, today's social production and production of solar energy in ordinary low-temperature solar hot water project has been far from meeting the demand, and thus solar water project came into being, it Can be a perfect solution to ordinary solar water heaters in the winter low temperature problem.
First, the comparison of energy consumption
Many families or units, are using electric water heaters, such as liquefied gas water heaters and other heating equipment, Shanghai magnesium double lotus solar energy for a variety of heating equipment to make a comparison of energy consumption:
Per ton of water heated from 15 ℃ to 55 ℃, need 48.8 kWh, according to the price of 1.00 yuan / degree, per ton of water needs 48.8 degrees
① electric water heater energy consumption for the daily average of 48.80 yuan per ton of hot water
② LPG water heater energy consumption for the daily average of 35.51 yuan per ton of hot water
③ diesel engine equipment, energy consumption for the daily average of 36.07 yuan per ton of hot water
④ solar water heating equipment for the daily average of 12.00 yuan per ton of hot water
⑤ heat pump hot water equipment energy consumption per day for the average daily 1.50 yuan
The resulting theory, the solar energy consumption ratio is the lowest, and in life now, is the most environmentally friendly energy.
Second, the cost of comparison
① electric water heater life of 4-5 years, maintenance costs at least two thousand dollars per year
② liquefied gas water heater maintenance costs at least a thousand dollars per year safety performance risk of poisoning
③ diesel boiler equipment life of 4-5 years maintenance costs at least 20,000 yuan per year
④ solar water heater equipment life 10-15 years maintenance costs zero yuan
⑤ heat pump hot water equipment is generally poor service life is 3 years, the best is 5-7 years maintenance costs at least 2 thousand dollars per year. However, with the best use of solar energy.
