Features of EVI air to water (air source)heat pumps:
It is mainly composed of compressor, heat exchanger, axial fan, heat preservation water tank, water pump, liquid storage tank, filter, electronic expansion valve and electronic automatic controller. After the power is turned on, the axial flow fan starts to run, and the outdoor air passes through the evaporator for heat exchange. The air after the temperature is lowered is discharged from the system by the fan. At the same time, the working fluid inside the evaporator absorbs heat and vaporizes and is sucked into the compressor. A low-pressure working fluid gas is compressed into a high-temperature, high-pressure gas and sent to the condenser. The water forced to circulate by the water pump also passes through the condenser. It is heated by the working medium and sent to the user for use. The working medium is cooled into a liquid, and the liquid is expanded After the valve throttles and cools down, it flows into the evaporator again, and the heat energy in the air is continuously "pumped" to the water, so that the temperature of the water in the heat preservation water tank gradually rises, and finally reaches about 55°C, which is just suitable for people to take a bath. It is the basic working principle of air source heat pump water heater.
EVI air source heat pumps are designed for domestic/commercial hot water and house heating in cold areas where lowest air temperature is above -25℃.
1. High COP to 5.2
2. Multifunction usage to choose: air conditioning, floor heating, cooling, domestic/commercial hot water
3. Efficient and Energy-saving
4. Enviromental friendly
5. Suitable any weather in any season
No matter it is rainy, snow, sunny, the EVI heat pumps always work as normal in high quality performance
Endurable
The Enhanced Vapor Injection (EVI) technology from Copeland compressor with crankcase heater for special cold area, Danfoss electronic expansion valve, Eaton AC contactor and thermal relay and other brand components of the heat pump guarantee high quality and a long lifespan. All of our screws and clips (both external and internal) are stainless steel. The cabinets we are using are made of GALVANIZED STEEL, making them more rust resistant, durable and affordable.
● Multiple Protections and wifi remote control
The system will be warning automatically if there is non enough water flow nor unstable power, or any others.
● Linkage Function
External signal on/off function
● Guaranteed Safety
Complete isolation of water and electricity avoids electric shock, explosion and poisoning; LCD screen digital controller for automatic operation
● Convenient install
With patented design for integration of spares, the EVI air source heat pump is easily to install in many places, such as garage, balcony, kitchen, etc.fix in one place or separately.
