Enhanced Vapour Injection (EVI)

Enhanced Vapour Injection (EVI) 

EVI Compressor systems present benefits over standard refrigeration compressors due to the following:

• Capacity Improvement

The capacity is improved by increasing the enthalpy difference in the system rather than increasing mass flow. This is accomplished without increasing displacements.

• Increased COP

The efficiency improves due to the fact that the gain in capacity is greater than the increase in power that the compressor consumes.

• Cost and Energy Advantage

Because a smaller size compressor can be used to achieve the same capacity as a larger conventional model, there is an inherent cost advantage.

EVI components:
Compressor:World famous brand -Copeland compressor
heat exchanger：tube in shell heat exchanger
electronic expansion valve
 tube in shell heat exchanger
accumulator
 filter
 gas-liquid separator
one way valve
 thermal expansion valve
4-way valve
 sensor
 injection in
injection out
evaporator
system balancing pipe
gas valve
 manometer
 pressure switch
refrigerant out

How to select a pool heat pump?

How to select a pool heat pump?

In our daily life,as a customer, some people didn't know how to select a heat pump? Because they didn't know  what is the most important to a heat pump. Beauty? Elegant? or other reason. 

To be frank, we take safety for serious, although some accident happen lowly. you may see news from all over the world, the bad quality heat pumps leads to unfortunately result. leak circuit, broken voltage. even explode a water tank.

what a unbelievable result. we just want to buy a safety unit.we just want to use comfortable and safety. 

All the trouble are due to bad quality heat pumps.some industry manufacturing less price heat pumps but lack of safety. 

but our company is one of the best quality heat pump manufacturer in China,we care what we sales.so we have our own strict way to control our heat pump quality during production process.
QC supervise every production process. leaks circuit,broken voltage are testing in the production line. 

I can show you this is the best quality heat pump we have.

See more details,please visits our website at:www.wotech.cn or contact us by social networks.

Advantage:

Easy operation and hot water keeping constant temperature. Heat pump water heaters adopt automate intelligent control system. Only need to be set at the first time and they will running according to the setting in 24 hours.

Safe and Eco-friendly. Water and electric are spit entirely in a heat pump water heater. No burning. No gas emission. Not affected by natural disasters.

Anti-freezing. Heat pump water heaters have intelligent defrosting functions to ensure they are capable of working in low ambient air temp. They decide to defrost or not according to ambient air temp, evaporator fin temp and unit running time.

Convenient installation. Heat pump water heaters can be installed indoors and outdoors. Roofs, grounds, everywhere. Heat pump water heaters also can be remotely controlled.

Long lifespans. Low cost of maintenance. Heat pump water heaters can work for 15 years or more.
