EVI Low temp. Industrial air source Heater Heat pump low cost Juteng Copeland compressor heating, hot water apparatus
EVI Air Source heat pumps transfer heat from the ambient air to water, providing high-temperature hot water up to 60°C.
The unique Low ambient-temperature heat pump is widely used for house warming. With innovative & advanced technology, the direct-heating heat pump can operate very well at -25℃ ambient temperature with high output temperatures up to 60℃, which ensures the compatibility with normal sized radiator based systems without supplementation.
Compared with traditional oil/LPG boilers, high-temperature heat pump produces up to 50% less CO2 whilst saves 80% running cost.
Our heat pumps are not only highly efficient, but also easy and safe to operate.
Working principle:
Compressor absorbs low temperature and low pressure refrigerant gas from the evaporator, then refrigerant compressed to high temperature and high pressure gas. The high temperature and high pressure gas goes into the condenser through fan to exchange heat with the air, and condensed into cryogenic liquid in the condenser and give off a lot of heat.
The air absorbs the heat and the temperature increasing. High pressure and low temperature liquid is throttled and depressurized through the expansion valve, absorbs heat from the surrounding air and volatilize into low pressure gas by fan in the evaporator, being compressed in the compressor, this repeated cycle, so as to continuously rise the water temperature.
PRODUCTION PROCESS of HEAT PUMP
1. Base plates go online
2. Install compressors, condensers and evaporators
3. Assemble and weld copper pipes
4. Recharged with Nitrogen
5. Water-inspection (Check if exist in air leakage)
6. Discharge Nitrogen
7. Vacuum air-removed
8. Add refrigerant
9. Halogen inspection
10. Fix fan component
11. Install electrical control
12. Security checks (Insulation, Ground connection, Dielectric Strength test, Leakage)
13. Run commodity inspection (The noise of components and parts, Function, Timing, shutdown, current, Difference in temperature)
14. Stick nameplate and connection diagram
15. Document attached (Product Manuals, instructions)
16. Final inspection (Appearance parts)
17. Packing
18. Tape-out
