What Are the Features of EVI Heat Pumps?

What Are the Features of EVI Heat Pumps?
Healthy and environmentally-friendly

Users don’t have to change the frequency when the system is running. Compressors just execute the mechanic movement, not producing any electromagnetic wave or health-threatening radiation pollution. The frequency conversion conditioning produce higher harmonic during the conversion, which is harmful to people and the equipment.

Flexible and good-looking
Heating can be at anytime when needed, not limited by the season. Central heating satisfied the users’ need. There is no bother to build boilers. Cost to build other equipments is cut. Installation and everyday maintenance is easy.

For more please visit www.wotech.cn.


What Are the Features of EVI Heat Pumps?

What Are the Features of EVI Heat Pumps?
1. Energy-saving and efficient.

The COP of all the models is averagely 4.32, which stands for the highest standard of the world. Due to the EVI technology, massive cost for heating and cooling is largely saved.
2. Running normally even in ultra-low temperature; reliable.
EVI heat pumps realize the ability to work under -25℃ to 29℃. EVI technology increases the compressor’s heating capacity under low temperature. 20% to 50% heating capacity is raised under -15℃.
The outside unit loses its heat exchanging ability under low temperature. The returning gas refrigerant is reduced, lessening the heating capacity of the compressor. But through refilling gas refrigerant with the mid pressure injection nozzle, the gas exhaust is increased. While indoor the circulating refrigerant for the heat exchanger goes up to realize pushing the heating capacity. EVI heat pumps are more suitable for the cold areas.

What Is Enhanced Vapor Injection?

What Is Enhanced Vapor Injection?


Enhanced Vapor Injection system is made up of EVI compressor, EVI technology and high-efficiency condenser. The combination of them provides high performance.

The compressor adopts double-level throttling and mid-air-injection technology, along with the flash evaporator to realize vapor injection effect. Under medium and low pressure, the compressor pressurizes the refrigerant and synchronously vaporizing it. Under high pressure, the compressor works normally. In low temperature, the heating efficiency is largely raised. The EVI technology is widely used for scroll and rotary type compressor.

Wotech has developed premium EVI heat pumps. For more please visit www.wotech.cn.

How Do Heat Pumps Work?

How Do Heat Pumps Work?

1. Temperature drops to -20 after the pressure release. When ultra-low temperature liquor cryogen enters and flows in absorbing heat evaporator, it meets air about 20℃;

2.Cryogen of 20 enters low temperature compressor, gets preasurized, heated up and turns into high pressure 80℃ gas.

3. Vaporized cryogen temperature of 80℃ passes heat to low cold water in heat exchanger, changing into 60℃ life used heat water which is pumped into warm keeping tank for storage throuth circulating pump. High temperature cryogen heat releases and turns into high pressure liquor.

4. High pressure liquor cryogen throttles and lowers pressure through expansion valve,entering into evaporator to absorb heat;

5. According to Reserve Carnot Circle Theory, compressor constantly repeatedly circles. The whole course is to transfer heat. As long as it use a kilowatt-hour electricity to drive compressor to work, it can absorb heat in the air equaling to that produced by 3-6kh electricity. Obviously it saves energy and works safely.

This is how Wotech heat pumps work. For more please visit www.wotech.cn.
