4 million hot water project of student dormitory building in Jinniu campus of Chengdu University

More and more school dormitories use solar or air energy hot water systems. Why? What are the advantages? 

The characteristics of air energy heat pump are introduced 

1. High efficiency and energy saving: air heat pump (unit) uses air as low temperature heat source to produce hot water, and the power consumption is only 25% of that of electric water heater; compared with coal-fired, oil-fired and gas-fired water heaters, it can save about 80% of the operating costs; in the heating process of air source heat pump, the electrothermal energy conversion efficiency can reach 450%, and the energy efficiency ratio is as high as 4.5; 

2. Environmental protection: the heat pump water heater has no emission and pollution during operation, which is green and meets the requirements of environmental protection; 

3. Safety: avoid flammable, explosive, leakage, gas poisoning and other hidden dangers in the ordinary water heater system; 

4. Reliable: stable operation performance, service life of more than 15 years, low maintenance cost; 

5. Simple: it can be installed on the roof, balcony, courtyard, basement and other positions, without special machine room, occupying a small area and convenient to remove; 

6. Unique structure: the heat exchanger has unique design, compact and beautiful structure, uniform air distribution, high efficiency and sufficient heat transfer; 

7. Modular design: flexible design of host and water tank configuration according to the actual water use situation of users to ensure that hot water is enough without waste; 

8. All weather operation: all weather operation throughout the year, not affected by bad weather such as night, cloudy day, rain and snow; 

9. Guarantee quality: the world's advanced U.S. Valley wheel ZW type heat pump special compressor and related accessories are adopted to guarantee the quality; 

10. Economic saving: high heating efficiency, saving investment and operation costs;
