We R&D Enthalpy-enhancing Heat-pump System independently.After years of customers' responses,the use of results are excellent.We are applying invention verification, we have achieved batch customers in OEM industry, according to patents for Enhanced Vapor Injection Compressor &4 Way Valve.
To operate the system with R134a refrigerant under working condition(Evap.Temp.- 15℃,Before Valve 35°C, Superheat 10°C) ,it is the working condition according to the national standard of “low temperature heat pump working condition".The Enthalpy-enhancing A/C System is providing 3 times more heat than PTC heater, COP reached 3.0.Mileage range of the pure electric vehicle was increased by 16.7% under the environment of-20--25℃.
We supply whole Enthalpy-enhancing Heat-pump System, include Enhanced Vapor Injection Compressor,4 way valve,and a multifunctional integrator that integrates functions such as flash dryer, accumulator, filter, expansion valve,etc..
POSUNG Enhanced Vapor Injection Compressor has applied for a national invention patent, and the Intergated Four-way valve
and the multi-function integrator have also applied for patents.
This system consists of three key components, including the Enhanced Vapor Injection Compressor, the integrated Four-way
valve, and the multi-function integrator, which form the basis of the Enthalpy-enhancing system.
On this basis, the passenger car Enthalpy-enhancing Heat Pump System is formed. Parking air conditioning and engineering
vehicle enthalpy-enhancing heat pump systems are currently used in thermal management systems to alleviate the problem of reduced vehicle battery charging and discharging capabilities at low ambient temperatures.
* Average COP can reach above 3.0.
* 3 times heating capacity than PTC.
* Working in the environment of -20°C to-25°C.
* Mileage increased by 16.7%, saving 1.2 kWh of electricity per hour.
* Compare to the PTC water heating, heat-pump system warms up quicker and more stable on the heat temperature.
* Power consumption is 50% lower than the PTC heater module when working temperature at -5°C
