DC INVERTER INTEGRATED Heat Pumps for HeatingCooling
DC INVERTER INTEGRATED Heat Pumps for HeatingCoolin utilize advanced heat pump technology to achieve high efficiency with With the application of DC inverter technology, these series of units can adjust the output capacity automatically and control the room temperature accurately. The intelligent control system means everyone in the family can control the unit. Due to the monobloc design, the units are cost effective, space saving and quiet to run outside. All of these features work together to give you a more comfortable home.
Energy Saving up to 20%-40%
With the use of inverter compressors, brushless DC fan motors and PFC control method, the units can regulate the running capacity . With no frequent start-ups and stop runnings, the units work in stable condition with high efficiency. The energy consumption is 20-40% less than that of standard heat pump units.
0.5 oC Precise Control
The units can change the operating frequency of the compressors automatically according to the heating or cooling demand. When the target temperature is reached, the units run at a lower frequency, and the temperature control accuracy can be as precise as 0.5oC. high temperature control
Speed up Heating/Cooling Time
When there is a large difference between the actual temperature and the programmed temperature, the unit can run at a higher frequency to make fast heating or cooling to increase or decrease the temperature rapidly. speed up heating cooling
Traditional defrosting method is with fixed defrosting time and start temperature . Once the ambient temperature reaches or is lower than -7oC, the unit will start defrosting. It's easy to cause energy wasting when there is no defrost and will reduce the heating performance at the same time.
intelligent defrosting uses pressure sliding defrosting technology to figure out the exact defrosting time and start pressure according to the real ambient temperature. It saves energy and makes the heat pump work in high efficiency.intelligent defrosting No frosting in the bottom With the use of the special liquid distribution technology, in heating mode, the temperature of refrigerant in the air exchanger’s bottom copper tube will not decrease in order to ensure no frosting on it and smooth drainage.
VKIN self-developed wire controller with glass panel and touch screen can be installed on the wall inside the house. It provides you a convenient way to control the heat pump and is applicable to RS485 communication.
The use of the famous and reliable brand compressor ensures the unit working in the perfect performance..
