In the past, solar water heaters were very common, and when there was sunlight, hot water did not need to consume electricity at all, which was favored by the people. However, solar energy also has some shortcomings, that is, too dependent on the weather, 365 years a year, there is no sun of the time, at this time can only rely on electric heating. Therefore, when used for heating water in winter, the energy saving effect of solar energy will be greatly reduced due to the relatively few days of sun. Therefore, in order to reduce operating costs, many large places have chosen a combination of solar energy and air energy for heating. Although the investment cost will be higher, the energy-saving effect will undoubtedly be significantly improved.
Recently, under the commission of a unit in Changzhou, Jiangsu Province, our company undertook a set of air energy + solar hot water project, to send hot water warmth to the staff dormitory of this enterprise, the project consists of 60 groups of 58*1800*50mm solar engineering header, and 60 10P air energy heat pump water units. It can provide hot water for about 500 employees of the company.
First, the main features of solar + air source heat pump hot water system:
1, solar energy, air source heat pump hot water system control technology intelligent, to achieve a large extent of the use of solar energy, low consumption of auxiliary heating energy;
2, sunny days fully use solar energy, can supply hot water 24 hours;
3, can be constant temperature direct heating water;
4, rainy days with air source heat pump auxiliary heating with electric heating backup emergency system, to use how much hot water to heat how much, energy saving, convenient;
5, solar + air source heat pump central hot water system, with automatic heating, temperature control, automatic operation and other characteristics. It is a hot water system with a very high safety factor in all central hot water systems, automatic water intake and automatic pressurization, saving manpower, material resources and financial resources for enterprises and institutions.
Two, solar + air source heat pump hot water system advantages:
1, the use of intelligent constant temperature direct heat operation mode, can ensure that the water directly into the thermal insulation tank under constant temperature conditions do not meet the requirements of the use of hot water;
2, the use of hot water full temperature difference cycle operation, can avoid the constant temperature DC mode in the case of users do not use hot water for a long time, the system heat loss needs to supplement the drawbacks of auxiliary heating;
3, the use of temperature and frequency conversion control pump heating water, to solve the heating water pipe heat caused by the water temperature reduction and other problems;
4, the use of intelligent direct heat air heat pump assisted constant temperature heating, efficient and rapid solution to rain, rain, snow, freezing weather and other solar insufficient heating water problems;
5. There is a unique heating emergency backup system to ensure the hot water supply in any unexpected emergency.
The use of air source heat pumps in hotels, hospitals and dormitories saves 3/4 of the cost per year than electric water heaters, 2/3 of the cost of fuel savings, and 1/3 of the cost of gas water heaters. Moreover, the air source heat pump hot water system is easy to install, safe, environmentally friendly, does not require special management, fully automatic operation, and has a life of more than 15 years. As a professional brand in the heat pump industry, Impor undertakes the construction of air energy heat pump projects with strong energy saving, high safety and good stability, which can fully meet the water needs of users!
