Domestic DC Inverter Hot Water Heater

Main quality control project list:

1. Check all parts before assembling.

2. Charge nitrogen to test leakage and pressure maintaining after welding system.

3. Vacuumize, the vacuum pressure ≤30Pa

4. Leakage detection by halogen after charge refrigerant.

5. Safety testing: High-voltage insulation test and ground resistance.

6. Operation testing, record refrigerant pressure, temp. etc.

7. Inspect inside unit’s cleanliness and appearance.

Air and water source heat pumps Main components and Effect:

1. Compressor: Famous Brand Panasonic, Sanyo, Mitsubishi,Toshiba Rotary Compressor or Sanyo, Copeland, DAIKIN Scroll Compressor with environmentally friendly Refrigerant gas R407C/R410A/R134a/R417A

Effect: Compress and transport cycle fluid from low temperature low pressure to high temperature high pressure, it’s the heart of heat pump system.

2. Evaporator or heat exchanger: Hydrophilic aluminum foil Finned tube Heat Exchanger.

Effect: It’s the cooling output facility. Evaporate the refrigerant liquid which flowing through the expansion valve to absorb the heat from the cooled object,  so achieve the purpose of cooling.

3. Condenser: Coil type, plate type, casing type, High efficiency tube in shell heat ex-changer or Titanium heat ex-changer.

Effect: It’s the heating output facility. Heat absorbed from the evaporator with the converted heat by compressor power consumption is carried away by cooled medium in the condenser, to achieve the purpose of heating.

4. House casing: anti corrosion and rustproof Stainless steel or Spray coating metal plate for whole set of casing, Buttress and frame system, Electric Control Box etc.

5. Microprocessor automatic Controller sets: LCD touch screen Wifi Display, Neatly wiring PCB Board in individual controller box, Whole sets of temp sensors, Capacitors, Transformer.

6. Copper Pipes: throttling device, pipes connect all system, compressor, heat ex-changer, EEV and so on sub-assembly. 　

7. Thermostatic expansion valve or Japanese Sanhua Electronic Expansion valve and 4-Way Valve

EEV Effect: For circulating fluid Throttling depressurization and adjust the flow of cycle fluid into the evaporator. 

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.

How to select water tank:

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
