Ground source heat pump is a new-energy technology by applying shallow geothermal energy for heating and cooling. Ground source heat pump usually is able to transfer the heat or refrigeration underground to the place where energy is needed. To a large sense, heat pump is used for cooling or heating by the air-conditioner. Ground source heat pump has used enormous regenerative thermal storage capacity of underground soil, which enables that heat can be transferred from underground soil to the house in winter; while cool air can be transferred to the house in summer. A cool-heat cycle has been formed by using this technology.
Advantages of ground source heat pump
1. High efficiency, energy-saving and reliable
The geothermal energy or the surface temperature of shallow geothermal resources remains relatively stable throughout the year. The temperature gap between soil and air is 17 degrees usually. It is higher than the ambient air temperature in winter and lower than the ambient air in summer, which offers good heat source for the heat pump and cold source for air-conditioner. This temperature characteristic enables the operating efficiency of ground source heat pump 40%-60% higher than that of traditional air-conditioner. That is to say, the energy and operating cost can be saved 40%-50% than before. Usually, once the ground source heat pump consumes every 1KW of energy, the users can enjoy more than 5KW heating energy or 4KW cold energy that is why we call this energy-efficient air-conditioning system.
2. No environmental pollution
Pollutant emissions of ground source heat pumps are 40% less than that of the air source heat pump; compared with electric heating, there is a decrease of more than 70%. The ground source heat pump has realized energy conservation in a real sense.
3. One heat pump integrated with multi- functions
Ground source heat pump is able to provide heating, refrigeration and domestic hot water. One pump integrates multi-functions. One set of system could replace the original two sets of boilers and air-conditioning system.
4. Low maintenance costs
The operating units of ground source heat pump are less needed than that are needed in the conventional systems, thus the maintenance costs are reduced. The system is installed indoor instead of exposing outside, which stops the system from destroying, and enables the long-term usage.
5. Endurable in usage
The underground pipes of the ground source heat pump use polyethylene and polypropylene plastic tubes with life span of nearly 50 years. The life span of the ground source heat pump is 35 years than the ordinary one.
6. Saving space
With no cooling tower, boiler rooms and other devices, the relative space in need is saved. Thus the additional economic benefits are generated and the external image is improved.
The energy of the ground source heat pump system derived from natural energy. It is an ideal “green air-conditioner” for it emits no exhaust gas, waste water and waste to the outside world. It is considered as the most environmental friendly and most efficient heating and cooling system.
