Ⅰ.Introduction on SUNDEZ ground source heat pump

1. Characteristics

●

●

High quality construction

Quiet operation

Sundez ground source heat pump is a heating system designed for operation as
brine/water or water/water heat pump. The heat pump extracts energy from the heat
source medium i.e. brine at a low temperature level. This extracted energy is then
transferred to the heating water at a higher level, enriched with the energy
transferred by the compressor. The underground heat can be transferred through
the horizontal or vertical underground loop system. The heating water can be heated
up to a flow temperature of 55 .℃

Cabinet--Standard unit fabrication consists of heavy gage galvanized sheet metal
cabinet construction that provides maximum strength. All exterior sheet metal
surfaces are powder-coated for maximum corrosion protection to ensure resilience
for long term vitality. Compact, stackable cabinets are designed to minimize
installation space.
Compressor--Standard high-efficiency scroll compressor design for all units.
Compressor isolating springs are specially selected for each compressor size.
Refrigerant/water circuit--Units have a sealed refrigerant circuit including scroll
compressor(S). Refrigerant circuits are provided with a standard thermostatic
expansion valve(TEV) for higher accuracy and performance. The condenser and
evaporator are brazed stainless steel SUS316# plate heat exchangers with the
highest heat exchanging efficiency, outstanding ability against high pressure and
lower water quality.

The whole unit is designed for quiet operation. Compressor isolating springs are
specially selected for each compressor size. The floating design of the compressor
support with rubber isolators which completely separate the compressor from the
cabinet, to minimize vibrations to the unit structure.

●

Built-in Hydraulic module, easy installation(Optional)

Hydraulic module(flow switch, expansion tank, water pumps, 3 way solenoid valve is
built-in.
