Detailed Description
25KW Geothermal Water Source Heat Pump HVAC Most Efficient Heat Pump
1. Geothermal source heat pump types
There are four basic types of ground loop systems. Three of these:horizontal, vertical, and pond/lake,are closed-loop systems.The fourth type of system is the open-loop option.
Which one of these is best depends on the climate, soil conditions, available land, and local installation costs at the site. All of these approaches can be used for residential and commercial building applications.
(1) Closed-Loop Systems
Most closed-loop geothermal heat pumps circulate an antifreeze solution through a closed loop,usually made of plastic tubing,that is buried in the ground or submerged in water. A heat exchanger transfers heat between the refrigerant in the heat pump and the antifreeze solution in the closed loop. The loop can be in a horizontal, vertical, or pond/lake configuration.
One variant of this approach, called direct exchange, does not use a heat exchanger and instead pumps the refrigerant through copper tubing that is buried in the ground in a horizontal or vertical configuration. Direct exchange systems require a larger compressor and work best in moist soils (sometimes requiring additional irrigation to keep the soil moist), but you should avoid installing in soils corrosive to the copper tubing. Because these systems circulate refrigerant through the ground, local environmental regulations may prohibit their use in some locations.
(2) Open-Loop System
This type of system uses well or surface body water as the heat exchange fluid that circulates directly through the GSHP system. Once it has circulated through the system, the water returns to the ground through the well, a recharge well, or surface discharge. This option is obviously practical only where there is an adequate supply of relatively clean water, and all local codes and regulations regarding groundwater discharge are met.
