DC Inverter Split Heating&Cooling Air Source Heat Pump, -25
Degree Low Temperature Heat Pump
We are considering A solar heat pump and ground source heat pump
combined air conditioning system and control method, comprising a
solar heat collection unit, a heat pump host unit, an underground
heat exchanger unit, an indoor terminal unit and a control unit,
the solar heat collection unit and the underground heat exchanger
unit , The indoor terminal unit is respectively connected with the
heat pump main unit, and the control unit is respectively connected
with the heat pump main unit, the underground heat exchanger unit
and the indoor terminal unit. Through the above method, the present
invention can realize heating in winter and cooling in summer. The
solar heat pump heating mode is turned on during sunny days in
winter, and the excess heat is stored in underground soil when the
solar radiation intensity is sufficient; the ground source heat
pump heating mode is turned on on cloudy and rainy days in winter
and at night. , The ground source heat pump cooling mode is turned
on in summer, and the energy storage mode is turned on during the
transitional seasons of spring and autumn. The air-conditioning
system always maintains efficient operation and continuous heating
or cooling, saving energy to the greatest extent and keeping the
underground temperature field balanced.

More comfortale:
Water is used as the air-conditioning medium, the temperature of
the air outlet of the fan is 13-15℃, and the relative humidity is
30%-45%, which effectively maintains the temperature environment;
Energy saving
The main engine is controlled by frequency conversion. When the
internal machine is running at low load, part of the main engine
works, which is highly efficient and energy-saving; the secondary
system design is adopted, and the end water pump is controlled by
frequency conversion. When the use area is small, the pump runs at
low frequency, which can greatly reduce the energy consumption of
the pump. Loss; the water system is more energy efficient than the
fluorine system by 20%.
More reliable
The indoor unit is only a simple heat exchange function. The two
are independent of each other and do not affect each other. The
indoor unit or the outdoor unit can be maintained separately;
multiple hosts are independently designed. If one system fails or
has a problem, other systems can still be used.
Easy maintenance
Using water as the refrigerant carrier makes leakage easy to detect
and convenient for maintenance as soon as possible. The internal
unit of the air source heat pump adopts a fan coil unit, which is
versatile and easy to replace. The fan coil unit is controlled by
an independent indoor temperature control, and the high efficiency
is simple.
The air source heat pump is easy to maintain in the later period
and the cost is low
Safety
Low-pressure water system leakage is extremely unlikely, even if
the leakage is very obvious, it is harmless to the human body
