What Is 4-Way Valve of Heat Pump?

What Is 4-Way Valve of Heat Pump?

Four-way  valves have four pipe connections.  It controls the switch of high/low pressure, heating and cooling. It is a necessary component of heat pumps.

Wotech is strict with every component. Before production, every component is 100% checked. For more please visit www.wotech.cn.

What Is Water Flow Switch?

What Is Water Flow Switch?

A water flow switch controls the water circulating of water heaters, air conditioners and heat pumps. Water in-and-out control, water heating, water pump switch control, etc. can be manipulated by water flow switch.

It monitors the water flow and flow conditions within the pipe. It tells whether the water is flowing or not, whether water exists and the speed of flowing.

Heat Exchanger from Wotech Heat Pump

Heat Exchanger from Wotech Heat Pump

As for heat exchangers, we use tube-in-shell type. The outside shell is carbon steel, inside is copper tube with fins. Water goes through the tube while refrigerant passes the space between the tube and the shell. They exchange heat completely.

We are one of the most advanced companies getting approval by government to produce this kind of high-efficient heat exchangers. The standard is high and strict. But we have reached it.

Trust us. We will prove that we are loyal to you, as our customer. For more please visit www.wotech.cn.

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.

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.
