Air Source Heat Pump Trigeneration Technology
Research &
Development
Air Source Heat Pump Trigeneration Technology
One system meets the needs of all seasons. It can meet the needs of central air conditioning cooling, floor heating and four-season constant temperature hot water, and hot water can be obtained free of charge through heat recovery.
Aluminum Heat Exchanger Fast Defrosting and Snow Melting Technology
Adopting aluminum fin evaporator technology, it effectively improves the evaporation efficiency of air for the working conditions under special air energy environments, and can effectively heat at -35℃
Water System Anti-Leakage Automatic Water Replenishment Technology
The intelligent constant pressure monitor is applied to the water system, which can not only solve the automatic water replenishment of the water system, but also judge the system leakage to achieve the alarm function. Users can use the APP to add water in real time, eliminating the trouble of manual water addition
High-Temperature Heat Pump Technology
The unit can meet three types of heat energy: 75℃ high temperature/90℃ ultra-high temperature/120℃ ultra-high temperature, and is suitable for harsh environments with ambient temperatures of -35℃ to 50℃. It is in a leading position in the field of high-temperature heat pump technology
Intelligent Remote Diagnosis Technology for Heat Pumps
Always monitor the operating status of the equipment. If the operating status is abnormal, the background will automatically alarm, and troubleshoot the customer as soon as possible, saving time for on-site maintenance
