A water source air-conditioner or heat pump is a variation of a traditional air source heat pump. The explanation that follows first describes how a cooling-only water source air-conditioner. works. A description of a heat pump (heating and cooling) will follow.
Geothermal Heat Pump Monitoring Systems. Geothermal heat pump systems collect and use renewable solar energy stored in the subsurface to heat and cool buildings. Ground Energy Support (GES) is dedicated to providing unbiased, high quality data and objective analyses to support the development of ground source heat pump technology. Performance Monitoring.
