Office Building Central Air Source Heat Pump In Cold Climates Air Conditioner Unit
About ASHP
User-friendly interface operation
It adopts a microcomputer control system with display, control and protection functions. User-friendly interface operation, monitoring the operating status of the unit at any time.
Simple system
No need for cooling tower, cooling water pipeline and machine room, installation is simple and convenient, civil construction investment is small; no fuel is required, fully automatic operation, additional operation cost is small; unit is connected with central air handler, summer cooling, winter heating, heating is not A separate thermal station is required.
High effeciency
The heat recovery technology partially realizes water cooling and has the characteristics of high efficiency of water-cooling unit. It not only utilizes waste heat, but also obtains free hot water, directly reduces waste heat and heat, protects the environment, improves unit efficiency, reduces failure rate, and prolongs its life span
Quiet.
The low-noise axial flow fan is equipped with a damping device for low noise.
The modular design of the unit can be arbitrarily combined according to the load, convenient for transportation, installation and maintenance; the unique pipeline design ensures that the unit can still start running under the winter environment temperature of -25 °C.
Applications
It could be connected with air conditioner fans.
in summer , 7C cool water circulate inside the system;
in winter, 50C hot water circulate inside the system.
It is more confortable than conventional AC unit
