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.
