Air Source Heat Pump Unit for School Hot Water Heating System

Short Description:

With the improvement of energy-saving and low-carbon awareness, schools pay more and more attention to the construction of campus hot water system. The comfort of using hot water, energy-saving and low-carbon benefits of hot water equipment have become the two rigid instructions of campus hot water system. In this context, heat pump becomes the first choice of school hot water system. At present, many schools are using air energy heat pump.

Essential parts of a centrial heat pump water heating system

Why air source heat pump is popular for school hot water heating systems?

Because the hot water consumption of school students is huge, the speed of water use is fast, the frequency of use is high, and the repetition rate of users is high.
First the traditional hot water equipment can not meet the requirements of the school in terms of comfort;
Second, it can't meet the requirements of the school in the production of hot water;

Third, the safety factor can not meet the requirements of the school standards, the most important thing is that the cost of traditional hot water equipment to produce hot water is very high.

But the air energy heat pump is different. The air to water heat pump uses the heat in the air to heat water. Therefore, it can be used wherever there is air. It has strong adaptability, no matter in summer or winter, south or north, the air energy heat pump can provide stable heating, providing comfortable and constant temperature hot water service for teachers and students.

What’re the advantages of air to water heat pump?

Because the air energy heat pump mainly uses the heat in the air for heating, not directly for "electricity heat" conversion, plus the air energy heat pump does not use gas, oil, coal and other fuels, the heating process has no open fire, no emissions, so there will be no fire, explosion, poisoning, electricity leakage, gas leakage and other safety hazards when using the air energy heat pump.

At the same time, it is precisely because the air energy heat pump does not directly use electricity to heat cold water, so the heating efficiency of the air energy heat pump is as high as 400%, that is, 1kW electricity generates 4kw heat energy, and heating a ton of tap water (15 degrees to 25 degrees) only needs about 11 degrees electricity.
Features:

1. Air source heat pump is energy saving device.

2. Regular constant temperature and pressure hot water supply to ensure students’ comfort.

4. The whole system is fully automatic control operation, without special guard.

5. The whole hot water pipe network can be designed with a pressurized return water system, only need 5 seconds to get hot water after turn on the tap.

6. The heat pump has high stability, safe use, low operation cost and maintenance cost.

7. Environmental protection, safety.
