Air source monobloc water heater 20kw heating/cooling and hot water made in China DAO-20HAS/3
All hydraulic parts are located within the outdoor unit. Water pump, expansion vessel, buffer tank and safety equipment have already been fitted inside the outdoor unit. The hydraulic connection rather than refrigerant makes installation much quicker and easier for the domestic installer.
PRODUCTION PROCESS of Air source 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
Daishiba Luxury air source heat pump provides energy-efficient space heating, cooling and domestic hot water for residential and small commercial application.
