Heat pump water heater

GENT 20P EVI top blowing heat pump water heater 

Product model: GNTRS-72-DB 20P EVI top blowing

Inverter unit:

This heater pump water heater is an inverter heat pump, which means the unit starts with variant frequency, and it can automatically adjust the operating frequency, and it has strong environmental adaptability.

Detailed description of some parts of the air to water heat pump:

Heat exchangers on the outdoor air side:

1.Type:

Evaporator with copper pipes and hydrophilic aluminum foil fins

2.Composition:

① Fin type: corrugated sheet

② The machine adopts high purity and seamless copper pipes with internal thread, which has long service life and high heat exchanger efficiency and is not easy to break and be corroded.

③ The outer frames at both ends of the fin for fixing the coils are made of 304 stainless steel plates, and this kind of steel plate has high strength, and is less prone to corrosion and deformation.

④ Hydrophilic film with corrosion resistance can effectively prevent condensate forming water beads on the fin, and this ensures the machine’s heat transfer efficiency and low noise and makes the fin resistant to corrosion.

3.Features:

① The unique method of liquid separation of the machine can ensure uniform liquid distribution on the windward side of the coil.

② After the copper pipes are loaded into the fin, they are mechanically expanded or ultra-high pressure hydraulic expanded to ensure close contact with the fin for better heat transfer effect.

③ The selectivity of fin spacing is large, which can effectively avoid coil frosting.

④ The refrigerant coil is subjected to high-temperature heating and vacuum drying operation to ensure that there is no water in the cavity.
