Copeland EVI scroll compressor
World-famous scroll compressor with low energy consumption and high energy efficiency output, which effectively shortens the heating water time and double extends the useful life of the unit.
Working temperatures range from -25 to 43DegC, enhanced vapor injection (EVI) is the latest scroll compressor technology.
Based on the EVI compressor, TONGYI optimizes refrigerant injection technology with drive set, scroll set, and high efficient motor. TONGYI EVI heat pump can increase over 20% heating capacity even though works under severe weather.
Internal thread tube in the tube heat exchanger, dual cycle and multipath wavy, coaxial and spiral design
The system runs safely, steadily, and reliably thanks to our full protection: high-temperature protection, compressor overload & overheat protection, power phase sequence & over/under voltage protection, etc.
EEV, precise flow control
Wide working temperature range, faster and more accurate refrigerant flow control than capillary and mechanical expansion valve. Best choice to achieve higher efficiency and energy-saving.
Auto-defrosting program and anti-freeze
Intelligent defrosting technology, which can determine the time of defrosting according to the operating conditions of the unit (running time, exhaust temperature), ambient temperature, and thickness of frost, so as to achieve intelligent defrosting when it is necessary, which greatly shortens the defrosting time by more than 20% and ensures the high heating capacity.
The Cuboid shape module design of the unit makes the project installation save more space.
BMS contact point / Modbus support(with RS485) to Amazon cloud, realize remote control function optional
With IoT technology, we can check the heat pump status remotely. When there is fault occurs, it is easy for us to check the product information and give immediate support to our customers.
With OTA(update over air) technology, If there is an error that happens on the software, we can do the remote service by updating the software online. And when the software has a new version with the function upgraded, as long as we got your permission, we can update the software remotely.
It uses an outer rotor axial flow silent fan with a five-leaf balanced aluminum alloy wind wheel. It has the advantages of corrosion resistance, large air volume, and low noise.
Patent louvered casing
TONGYI’s patent louvered casing can be better for waterproof, windproof and dust-proof. Patent no.:CN201030670236.9.
Unique hydrophilic fin coil heat exchanger
Large amount for air inlet, Air exchangers(fin-coil)with hydrophilic coating are strongly anti-corrosive and perform at high efficiency.
Quality is taken into account since product design through the whole product life-cycle. With professional design procedure, simulation, and over 30 type tests, from incoming parts inspection to out-going heat pump inspection during production.
With the Research center, product design department, and product engineering team, we have technical talents with over 20+ years in heat pumps, the development is managed by PLM(Production Lifecycle Management system) with the design procedure.
