Units Features:
Ground source heat pump system can adopt water of lake, river, underground and ground heat source; With compressor and electrical power, it can transmit heat from water into the room in winter, and from room into water in summer to achieve the purpose of air conditioning.
Environmental-friendly
In heating mode, it can replace the boiler system to avoid smoke-pollution. In cooling mode, it can avoid noise and leaf mold from cooling tower to protect environment.
Energy Saving
In winter, user can get 5KW heat power with 1kw electrical power. In summer, uses can get more than 5KW cooling power with 1kw electrical power. The efficiency is 3-4 times as that of electrical heater.
Space-saving
No need of Boiler and relevant equipment, by which can save space.
Water-Saving
Cooling or heating can be realize by discharging or absorbing power into the water; water source will not be consumed neither be polluted.
Money-saving
Cooling or heating can be realized by one system; its investment is 1/2-2 of that of traditional equipment.
Features
Optimized design
It is designed in line with international standards.
Its concept that, big temperature gap and small water flow save more water and more operational cost for the user.
CAD guarantees the best operation under various conditions.
Choose good components
World brand compressor and components guarantee the unit an efficient and reliable operation.
We have years of experience on central air conditioner’s design, test, and development. The efficient heat exchanger is researched and developed with the collaboration of our company and domestic professional matching manufacturers.
The controller is excellent. Its main engine has edges on similar products on intelligent management and networking, since it is integrated with special water source heat pump control system.
Convenient management, reliable operation
Pc control, in addition with manual controller.
Perfect PC control and multi-protective measure guarantee a safe and reliable operation.
Strong electricity and weak electricity are separated, avoiding electromagnetic interference, providing a more safe management.
