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.
Compressor gets the low temperature and low pressure air refrigerant from evaporator, then turn it into high temperature and high pressure air, this air gets into the condenser to exchange the heat with water, then the condensed air become low temperature fluid and release lots of heat energy.
Water gets this heat energy and become hotter and hotter.
This high pressure and low temperature fluid become low pressure by the primary flow meter device.
This low pressure and low temperature fluid, gets into the evaporator, Under the function of rotation fan, heat energy from air is absorbed by the fluid and becomes low pressure refrigerant,
then is absorbed by compressor, recycling to produce the hot water.
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.
Best Warranty and Fast Service:
1. MOQ: 1 unit (For a larger order, the price will be fixed upon receipt of a definite order)
2. Delivery Time: 7~15 working days after the order is confirmed
