Central Air to Water Underfloor Heating Station Suitable For Ultra
Cold Climate
About ultra low climate ASHP system
1.Ultra-low temperature operation
The unit is designed for the climatic characteristics of severe
cold regions, and can efficiently obtain heat in a low temperature
environment of -25 °C, generating a steady stream of hot water,
supplying room heating and domestic hot water.
2, energy efficient
The unit adopts the world famous brand compressor and applies the
second generation high-temperature jet boosting technology to
achieve the highest energy efficiency of the domestic
low-temperature air source heat pump, saving users more operating
costs.
3, efficient heat exchanger
The shell-and-tube heat exchanger is used, and the heat exchange
efficiency is high.
4, easy to operate, easy to maintain
The unit uses a microcomputer controller. The operation is simple,
the control unit is safe and precise and fully automatic, no need
for special management, and advanced fault self-diagnosis function.
5, anti-freeze function
The anti-freezing function of the waterway system can safely use
the pipeline and system even if the ambient temperature is lower
than O °C, avoiding ice blockage and cracking.
6, a variety of refrigerant options to meet the different needs of
customers
The unit can supply R22, R4O7C and other refrigerants according to
customer requirements.
Applications
Indoor floor 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.
