The character of ground (water) source heat pump central air condition system
1. Reproducibility
Ground (water) source heat pump is a kind of Heating Refrigeration and Air Conditioning System, which use the solar energy stored in the Earth as the cold and heat source, and make the energy transfer. Ground (water) source heat pump use the technique of clean and renewable energy, surface soil and water is a huge solar collector, the collection of solar radiation energy, are 500 times more than the annual use of energy (underground water get solar radiation energy through the soil indirectly), it is also a great dynamic energy balance system, the surface of the soil and water maintain the relative balance of energy reception and radiation. The successful use of technology of ground source heat pump, making that the use of unlimited solar energy or geothermal energy which storage in earth become a reality.
2. Energy-efficient
Ground (water) source heat pump uses the soil or water, whose temperature is 12~22℃ in winter, the temperature is higher than the ambient temperature. The cycle evaporation temperature of heat pump rises, then the energy efficiency is also improved; soil or water temperature is 18~32℃ in summer, the temperature lower than ambient temperature. Refrigeration system condensing temperature decreases, the cooling effect is better than air-cooled and cooling tower, Unit efficiency is greatly improved, and it can save 30~40% of the running costs. 1KW of power can get more than 4KW heat and more than 5KW cold energy.
3. Major environmental and economic effect
When the ground (water) source heat pump set is operating, it has major environment-friendly effect because of not consuming and contaminating water and not needing the boiler, the cooling power and the area to store the fuel. The power consumption of the ground (water) source heat pump set can be reduced by 30% comparing with that of the air source heat pump set and 70% comparing with that of the electric heating. The efficiency of its heating system can be improved by 50% comparing with that of gas fired boiler and 70% comparing with that of oil fired boiler.
4. Multi-function for one set and widely application range
The ground (water) source heat pump system has multi-function: heating, refrigerating and supplying hot domestic water. One set of this system can replace the original 2 sets of equipments or systems—boiler and air-conditioning. The ground (water) source heat pump has major advantages especially for the buildings needing the heating and refrigerating. It not only saves lots of energy but also reduces the primary investment of the equipments. The ground (water) source heat pump can be applied to the hotel, residential area, factory, shopping mall, office building, school, hospital, etc. The small size ground (water) source heat pump can be more suitable for the heating and refrigerating of the villa house.
5. Automatic
The ground (water) source heat pump set has high automatic controlling level and long service life because of its stable working condition, simple system designing, reliable operation and low maintenance cost. |
