Through over 20+ years of research and advancement, TONGYI heat pump has mastered mature inverter technology and has applied to different category of its heat pump products, including heat pump for house heating and cooling, commercial heat pump water heater, which has improved the energy efficiency of up to 20%-60%, bringing great energy savings to the customers.
New Gas Application
TONGYI heat pump products use R32 as refrigerant. Outstandingly leading the industry, heat pump product with new nature gas CO2 for commercial water heating solutions has developed and launched to the market as well.
The influence that the refrigerant do to the performance of the product is very critical. Not only does the refrigerant has to be stable, non-toxic, superior in performance, but also has to meet the requirement and environment rules of different countries. Last but not least, it has to be economic.
Also heat pump with R290, R454b,R1234yf, R1234ze, R744 is also available
Super Silence Performance
Through repeated advancement on internal structure, adoption of branded compressor, fan motor and inverter technology, TONGYI heat pump heat pump product can run very silently, the sound level of which is much lower than most heat pump product from domestic heat pump manufacturers.
TONGYI heat pump has a strong IoT technology thru 4G DTU and connection with AWS, which helps unit trouble shooting and optimizing in a better SLA. What’s more, OTA is available when necessary.
Product Data Monitor
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 the immediate support to our customers.
If there is any error happens on the software, we can do the remote service by updating the software online. And when the software has a new version with function upgraded,as long as we got your permission, we can update the software remotely.
Wide Application Range
TONGYI heat pump ’s heat pump product can satisfy various hot water demand with wide hot water temperature range from 7℃ to 90 ℃. And its application occasions covers from domestic to commercial. Particularly, the temperature of heat pump for water heating in commercial application can achieve as high as 90℃，which is very powerful and leading the industry ahead in China.
With the self-developed EVI technology and intelligent slide defrosting design, TONGYI heat pump house heating heat pump can operate stably in ambient temperature of -25℃, meanwhile supplies hot water of up to 60℃, and achieves a COP of up to 4.2. whose performance is very outstanding under super low temperature climate.
We always put quality on the top. For each process, we established clear work instructions and guidelines which let our workers easily and fully understand the production and their tasks, so that can ensure the quality. Meanwhile, we invest a lot of capital on advanced production technology and testing equipment. More importantly, Tongyi’s environmental simulation lab has the capacity of testing heat pumps under the temperature from -25℃ to +52℃.In addition to above, all the incoming, process and outgoing inspections are very strict.
Incoming inspection: All the key parts are 100% inspected according to international standard and customer’s standards.
Process inspection: Our IPQC will inspect all the process randomly.
Outgoing inspection: All finished heat pumps are 100% inspected before shipment according to international standards and customer’s standards. On request we can provide inspection reports to our customers.
