Dual core screw type EVI air to water heat pump unit adopts dual core screw type compressors in one unit. Dual core EVI technology is designed to break through the traditional extremity of application, to fulfill higher output temperature, to work at lower ambient temperature. The COP could reach 2.2 at -30 degree ambient temperature, which is a revolutionary technical breakthrough for EVI heating system.
So what are the advantages of dual core screw type EVI heat pump for heating compared with the normal EVI air to water heat pump for heating?
Fearless of Severe Cold
Dual core EVI Screw Type Air To Water Heat Pump unit adopts dual core screw type compressors in one unit, dual core EVI top technology, to break through the previous predicament in the heat pump industry that the output water temperature is not higher enough, and the unit couldn’t work at very low temperature.
Higher Temperature
It could produce 65 degree hot water at -35 degree severe cold weather, and 70 degree output water at -25 degree ambient temperature. The output temperature is the highest compared with other heat pumps.
Environmental Friendly Refrigerant
The unit adopts the environmental friendly refrigerant, without any pollution and harmful substance. The discharge of Carbon Dioxide release is 40% off, which will be safe and environmental protective.
Higher Efficiency and Energy Saving
The COP at -12 degree can reach 3.0, providing 3 times heating capacity of the input power consumption. High efficiency for heating could decrease the power consumption largely and save the electric charges.
Intelligent Defrosting
It could automatically adjust the defrosting cycle, the start and ending of defrosting, the working load when defrosting. Defrosting is high efficient and stable.
Large Heating Area
The heating effect is equal to 8 units 20 HP normal air to water heat pump, creating a warm and comfortable living area for users. The maximum heating area for one unit could reach as high as 10000 m2.
High Heating Capacity and Efficiency
The maximum heating capacity of one R134A unit is 350kW, while R22 is 700kW. The unit heating capacity is the highest compared with other competitors’.
Intelligent Control
It could intelligently control the start/stop of the unit, the power adjustment of the compressor. And it could automatically read the alarm of functional faults and do the automatic diagnosis, to achieve the goal of unattended operation.
Super Silent
After elaborate processing, the occlusion of the dual core screw in the compressor is very tight, the compressor works smoothly. It’s equipped with the specialized damper between the bottom and foot mounting. Blimp is optional according to the users’ request. Thus lower the running noise of the compressor largely and the out spread of inner vibration.
Smart Application
It’s widely used in all kinds of buildings, including residential buildings, shopping malls, hotels, office buildings, hospitals, schools.
