Lu Yu ultra-low temperature air source heat pump, operating temperature reaches minus 20 degrees. 
 Cooling in the summer to replace the air conditioning. 
 Heating in the winter to replace the boiler. 
 Domestic hot water system in the year to replace the water heater. 
 Lu Yu air-source heat pump units to achieve integration of the Trinity. 
 1. Energy efficient, low cost 
 Most efficient use of solar energy can save energy 75%, significantly lower operating costs, intelligent control, unattended, can save personnel costs, so the daily running costs low. 
 2. Safe, not dangerous 
 Unit did not exist in conventional energy explosive, toxic, and dangerous, not afraid of wind, rain, snow and therefore safe and reliable water system. 
 3. Green, pollution-free 
 Using the power clean and green energy, fossil fuels to avoid environmental pollution. Therefore, the system does not process hot water suspended particles of dust pollution, no waste, waste material generated, and no sulfides, nitrides, carbon monoxide and carbon dioxide emissions 

 Comply with national environmental policy, the country, provides users with a clean, comfortable living space. 
 4. Control of advanced, intelligent operation 
 System uses advanced intelligent control technology, the implementation of automatic control, the best economy, the supply of hot water can be set to all-weather, easy to use. 
 5. The entire heat pump system safe and reliable operation, long service life. 
 6. Running costs of electric water heater 1 / 4; gas 1 / 4; oil 1 / 2, the comprehensive energy efficiency reached 3.6-6. 
 7. Unit operating environment: 
 Unit in the temperature range of -15 ℃ ~ 50 ℃ within the normal work, ultra-low-temperature high-efficiency air-source heat pump can work in -20 ℃, and the biggest advantage of the device at low temperatures than conventional heat pump energy efficiency by 50 to 80% by the European Union market users and the general heating system using hot water in winter 
 8. Fault protection facilities 
 High and low pressure protection; phase sequence protection; overload; overload current protection; winter frost protection; exhaust temperature protection; high pressure relief system function; automation cream; parameter setting; Fault; intelligent control.
