What are the advantages of ground source heat pump

Ground source heat pump with the energy of the gradual shortage of science and technology meet the ever-changing product shipped born, we know air conditioning has always been the way people indoor temperature regulation sought after development so far, air conditioning is also showing a split air-conditioning - Central air conditioning - GSHP triple type acceleration development. As far the most popular form of air conditioning and most energy-efficient ground source heat pump at the same time by many acclaimed also implies some limitations, advantages and disadvantages of this article will GSHP comprehensive analysis, to help you fully understand the ground source heat pump Features. Before looking at the pros and cons of ground source heat pump, let us get to know about what is the ground source heat pump. 1. Efficient: general air conditioning heat exchangers called against air cooled heat pump, the disadvantage is that most needs hot weather or cold or heat when the cold efficiency decreased. Ground temperature substantially constant throughout the year at about 16 ℃, slightly higher than the average temperature of 1-2 degrees in the area, so that the heat pump in terms of cooling or heating conditions are in a high efficiency point. 2. Saving energy costs: winter running, COP of about 4.2, is put into 1KW power, available 4KW heat, summer run, COP up to 5.3, input power 1KW, 5KW available cooling capacity, the energy efficiency of electric heating 3-4-fold manner; and a heat exchanger does not require defrosting, reducing electricity consumption frosting and defrosting. Saving about 50% compared to conventional air-source air-conditioning. 3. Green: When heating is no combustion process, to avoid the smoke pollution, saving the time of cooling tower, avoid the noise and mold contamination. 4. Comfort: Because through hot and cold water pipes (or floor pipes, pipe wall) switch off the fan when completed by the ground source heat pump for heating and cooling, air conditioning and heating generated (or radiant heat) to be more than the conventional air-conditioning softer and more heat is not easy to catch a cold. 5. Save floor space: eliminating the cooling towers, boilers and ancillary coal shed and slag field, saving land resources, generate additional economic benefits and improve the external image of the building. 6. Security: no fire equipment, so that there is an explosion, fire and toxic hazard. 7. Long life of the unit: heat pump units work in long-term heat exchange good low-temperature wells (16 ℃) under, can greatly extend the life of the unit. 8. A machine: ground source heat pump heating system, air-conditioning, but also for domestic hot water, a machine, a system can replace the original boiler plus air-conditioning of the two devices or systems. 9. Renewable: regenerative properties of the soil has good winter through the heat pump will raise the earth shallow low heat for building heating, cooling capacity while the reservoir to prepare for summer use; summer through the heat pump transfers the heat inside the building to the ground to cool the building, while the reservoir heat to prepare for winter, to ensure that the heat balance of the earth. 10. Zoning can control: central air conditioning to enjoy quality, but also to achieve the effect of single-conditioned local control, there is no "big horse cart." The advantages and disadvantages of ground source heat pump - GSHP Cons: Compared with the traditional advantages of refrigeration ground source heat pump heating mode is obvious, but as a high technological content and complex systems in emerging devices, ground source heat pump in the current application there are also some shortcomings. First, the initial investment is relatively high ground source heat pump. A small home ground source heat pump system initial investment of more than ten million or more, the cost of ground source heat pumps on large commercial higher, although post-use low-cost, but to come up with hundreds of thousands of one-time money for initial investment or so many ordinary families prohibitive, now, home ground source heat pump installed users are mostly concentrated in the villa.
