About ultra low climate ASHP system
1.Fast heating, according to the actual load at the start of the
need to load the number of compressors to load, fast loading,
shorten the waiting time of customers, improve the comfort of air
conditioning.
2.intelligent control,Due to the adoption of the modular design,
the unit can be started in order to reduce the instantaneous impact
on the grid, saving energy.
3.The unit is used for real-time monitoring and control of the high
and low pressure, exhaust temperature and water temperature, and
uses multiple system protection, which can ensure the safe
operation of the unit in the best condition.
4.Excellent quality
The key components of the refrigeration system are selected
internationally renowned brand products, quality and stability.
5. Energy saving, the operating cost is only 1/4 of the electric boiler and 1/3~1/2 of
the gas-fired boiler, which not only saves a lot of electric
energy, but also saves operating costs.
6.Strong defrosting function and able to work reliably at ambient air
temperature of -22C
Applications
ASHPs are outdoor unit, four of them make a group of central
heating station.
Indoor underfloor heating is more comfortable than air conditioning
Two kinds of air outlet modes, the upper and lower air outlets can
simultaneously emit air, or the single air outlet mode can be
opened, and the wind angle can be flexibly adjusted. 3D diffuse
three-dimensional air supply technology, the hot air sticks to the
ground when heating, spreads, rises naturally from the downwind,
the room temperature rises evenly, reaches the comfort of the floor
heating, and the heating rate is faster than the floor heating. The
three-dimensional wind does not blow straight, and the whole
feeling is warm and comfortable.
