Three cases and three plans! Based on air energy + solar energy, explore new ideas for campus cleaning and heating!

A school is a high-density place, and students from high school to kindergarten are all minors, so the technical route of campus cleaning and heating has higher requirements regarding safety, environmental protection, and comfort.

Campus buildings have a special status between buildings. In the campus heating system, due to the different building functions, the building heat load is quite different and has the characteristics of periodicity and phase. Therefore, it is necessary to comprehensively consider the resources and energy factors around the school, the building envelope, and other aspects of the conditions, according to the characteristics of every project to choose the appropriate clean heating method.

Therefore, the school central heating system should achieve on-demand heating, balanced heating, and standard heating, and the heating temperature should be adjustable. In the early stage of heating, it should be able to provide high-temperature heating and rapidly increase the indoor temperature. When the building or one room is empty, it can realize a low-temperature heating work shift to reduce the temperature, the operating costs, and achieve the purpose of energy saving and environmental protection, reducing initial investment and operating costs.

Primary and secondary school kindergarten clean heating renovation project

Solareast Heat Pump Ltd. integrates factors such as comfort, stability, safety, economy, energy saving, environmental protection and other factors required by the "Campus Clean Heating" project, and adopts an air energy heat pump with more energy-saving advantages. This heating method is less dependent on resources and energy and can meet the requirements of the "Campus Clean Heating" project on the set goals.

Project advantages

1. Constant temperature and comfort. The Solareast air source heat pump cooling and heating fan adopts a convenient floor-mounted installation method, with directionable air outlet. With this installation method the heat flow is from bottom to top, which conforms to the heat diffusion and transfer method, and enhances comfort and environmental protection.

2. Frequency conversion energy saving. Equipped with a new intelligent frequency conversion control platform, the heating temperature can be adjusted at any time according to the demand, the stepless frequency conversion does not need to be started frequently, the response time is short, and the energy saving mode does not condition the unit’s work.

3. The cost is super economical. The annual operating cost of the project is 10 yuan/㎡, which is significantly lower than the original heating method. It is not only suitable for the needs of schools in the northern region, but also for the cooling and heating needs of hotels, guesthouses, hospitals and other facilities.

Clean Heating Project of Xingguang School in Taigu District, Jinzhong City, Shanxi Province

Project Introduction: The clean heating project of Xingguang School in Taigu District, Jinzhong City, Shanxi Province is located next to the Hanxi Line in Taigu District, Jinzhong City. The original heating demand of the school is about 10,000 square meters for the dormitory building and canteen and 5,000 square meters for the teaching building. Due to various external factors, central heating cannot be achieved, so the project is required to provide the most cost-effective clean heating solution according to the current situation of the school.

According to the building form, building purpose, usage characteristics and the heating demand of each building at different times, Solareast Heat Pump Ltd. has planned and designed a vacuum tube collector module + air source heat pump system solution suitable for distributed heating.

The effective combination of 42 tons of solar collector modules and 8 sets of 50P air source heat pump units significantly increases the system COP value and greatly reduces operating costs; at the same time, the dual heat source system effectively ensures the constant heating temperature of the system. The system can simultaneously meet the requirements of safety, efficiency, energy-saving and environmental protection for campus clean heating, completely get rid of the strong dependence of traditional heating methods and give the school a great advantage in the market.

I. Advantages of the project

1. Energy saving and environmental protection. Heat pump heating has the characteristics of long service life and wide application scenarios. Under the same temperature conditions, 40%-60% of energy costs can be saved. When the sun light collector resources are insufficient, the air can automatically start to provide heating protection, and the operation is more stable. The Solareast aurora air energy unit used in the project adopts ultra-low temperature energy-saving heating technology, which has more efficient heating, better throttling effect, and more sufficient heat exchange. The energy efficiency is more than 30% higher than similar products at low temperature. With the advantages of dual heat sources which complement each other can be reached an even higher operation efficency and increase the energy savings.

2. Economical. In terms of heating costs, the air heat pump can generate almost no cost, while the main energy source for heating comes from the heat in the air, the electricity is only used to run the heat pump. The energy employed to run the heat pump is only a quarter of the energy would need to generate the same amount of heat with an electric heater.

3. Comfortable and stable. The system conducts heating and circulation through the water pipings, the heating effect is natural and comfortable, and there is a certain heat storage effect. Not only that, the system is highly intelligent, easy to use and simple to operate, but is also very suitable for the needs of the school.

In the process of use, each component of the heating system is safe, convenient, environmentally friendly and economical, which is very suitable for school use, easy to operate, and saves money and manpower. The system in this way helps improving the comfort of students' learning environment. For the school logistics support department, especially the teachers who are on duty during the winter vacation, the system is regularly maintained by a indicated person, so there is no need for the teachers to make any operation, not even the settings, which saves a lot of trouble.

To resume, in the face of the special time-sharing demand of school buildings, the cost pressure of large heating demand, and the environmental problems of traditional heating, Solareast Heat Pump Ltd. School clean heating system solution can be terminated according to students' schedule. Intelligent control and background control; the heating system uses free renewable air energyand solar energy for heating. The school not only does not worry about energy costs, but also saves considerable and controllable costs.

in recent years, the promotion and application of clean energy heating and heating system solutions has been strong, with superior energy saving and emission reduction benefits. Solareast Heat Pump Ltd. provides a multi-clean-energy complementary system solution based on air energy + solar energy. Many classic model cases have been established in the field of campus building energy conservation.

With the obvious development trend of clean, intelligent and low-carbon heating on campus and the integration of new energy and Internet of Things technology, this trend will be further accelerated. With its advanced product technology and clean thermal energy system solutions, Solareast Heat Pump Ltd. is bound to promote the further development of the clean heating market.
