Detailed Product Description
Geothermal ground water source heat pump with cooling
Heat contained in earth, is called geothermal heat is usually used indirectly. Heat pumps taking heat from the ground are called “ground-water“. Heat is extracted using an underground collector. A heat carrying liquid is pumped through these pipes connected to the heat pump evaporator. The heat carrying liquid is non-freezing and ecologically harmless. Circulating liquid is cooled down in the heat pump evaporator and it is re-warmed in the underground collector by means of geothermal hea
GHP20/B-DNNNE, designed and tested by European standard EN14511, approved and tested by TUV china branch. Characterized by its high COP, competitive price and perfect quality.
HISEER geothermal ground source heat pump adopts the following world famous parts:
-
Siemens controller
-
SWEP or GEA plate type heat exchanger
-
Daikin compressor
-
Schneider A/C contactor
-
Emersion expansion valve
-
Emersion dry filter
-
Honeywell R410a refrigeration
HISEER GHP20/B-DNNNE, ground source heat pump, works by using heat stored in the ground from the sun's solar radiation to supply all of the energy required for a home's heating and hot water system.

How it works
There are three important elements to a ground source heat pump:
|
|
1.The ground loop
This is comprised of lengths of pipe buried in the ground, either in a borehole or a horizontal trench. The pipe is usually a closed circuit and is filled with a mixture of water and antifreeze, which is pumped around the pipe absorbing heat from the ground. The ground loop can be:
•Vertical, for use in boreholes
•Horizontal, for use in trenches
•Pound/Lake installation
|
|
2.A heat pump
In the same way that your fridge uses refrigerant to extract heat from the inside, keeping a ground source heat pump extracts heat from the ground, and uses it to heat your home.
|
|
3.Heat distribution system
This consists of under floor heating or radiators for space heating and in some cases water storage for hot water supply.
