Best Selling Cold Area Air Source Heat Pump Parallel System SDNA-075Y Underfloor Heating
Normal ASHP VS Cold area ASHP
Working conditions difference:
Normal air source heat pum could work at lowest temperature -10C , if enveironmental temperature is lower, the unit will have problems such as defrosting fault, comressor fault;
Cold area air source heat pump could work in extreme environment, where atmosphere temperature is low to -25C
Technology difference:
Many ASHP factories in sourthern part of china are start with air source water heater.Southern part is not as snow as northern part.
The defrosting in snowing weather is the main difference of products. Cold area air source heat pump could defrosting automatically, 90 seconds derfosting time which is only 1/6 of other products. Cold area ASHPs usually takes jet boosting technology, which ensure no heating decay in cold weather.
OUR PRODUCTS HAS BEEN TESTED BY 6 MILLIONING SAUQRE METER HEATING PROJECT IN COLD AREA.
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.
