1.High efficiency, energy saving, 2.Stable energy source temperature, 3.Its operation cost is 50% to 60% of the common A/C. - details see: https://www.machineto.com/8-40kw-mini-ground-source-heat-pump-10223098

1. Optimized design:
The strong and weak electricity systems installed separately to ensure safety.
Flexible high pressure system makes it lifetime longer.
Several ways of getting energy:
1) Underground water 2)Ground Surface water 3)Underground piping loop

2. Quality components selection:
Compressors and refrigeration accessories (such as dry filter, thermal expansion valve, liquid supply solenoid, liquid level mirror, high/low pressure control devices) all chosen world-renowned brand products to ensure that the unit reached an excellent level of performance
Using the most advanced DAE / DAC efficient heat transfer pipe, heat transfer surface with internal ribbed tube makes the heat transfer coefficient substantially increased; the heat exchanger unique structural design, the best way of copper tube layout and precision of refrigerant control technology, greatly improved the efficiency of heat transfer.
3. Simple and stable operation

Perfect control
1) Computerized co ntrol with standby manual operation system
2) Compressor Operation timing
3) Compressor automatic start-up sequence,
4) Alarm signals
5) Alarm reset
6) Water temperature control
7) Manual reset high pressure switch, Automatic reset low pressure switch
Protections that ensure its safe and stable operation:
1) Reverse phase
2) Lack phase
3) High/low pressure
4) Gas discharge
5) Outlet water temp. too low (high)
6) water stopped
7) antifreeze
8)compressor overheat etc.
High speed microprocessor is used.
