Water source (geothermal) heat pump using surface water as a source of heat and cold water temperature in summer than the ambient air temperature is low, so the cooling condensation temperature decreases, making the cooling effect is better than the air-cooled and cooling towers, winter water temperature is higher than the ambient air temperature , Heat pump cycle evaporation temperature increases, energy efficiency also increased; there is no air source heat pump winter defrosting and other difficult issues. In the use of water (geothermal) heat pump should pay attention to the following aspects:
In the use of water source heat pump technology, the previous hydrological analysis is particularly important, according to the actual situation of groundwater sources, the feasibility of research and analysis. Applicable principles: adequate water, proper water temperature, good water quality, stable water supply and reliable recharge. Therefore, the earnest, scientific hydrogeological exploration work is very necessary.
Water source heat pump central air-conditioning host, is the core of hot and cold sources, the quality of its direct impact on the reliability of the entire system and the use of results. It is recommended to choose domestic and foreign manufacturers with good reputation, especially excellent technical quality, long production history and good after-sales service.
As we all know, water source heat pump air conditioning energy efficiency (COP value, equivalent to the output power / input power) higher than conventional air conditioning, but there are limits, generally 4,6, but some domestic manufacturers nominal heat pump energy efficiency can reach 7 , As many as 8, even a few still have 11,12. This is not realistic, unscientific, is extremely irresponsible to the user, is a deception.
The key technology of water source heat pump is water well. Wells wells into the process is extremely important, must require large-diameter steel tube wells. France CIAT has unique technology and experience in wells, which can save some well water usage in the actual use and can successfully achieve the same pumping and filling.
As the water source heat pump central air conditioning system with high utilization rate, so the performance of the equipment, the quality requirements are relatively high, a variety of auxiliary equipment and materials reasonable match is to obtain good results. CIAT's consistent style is to maintain a high level of engineering construction, the selection of high-quality equipment and materials, the project made display, promotion window, for the owners to bring better social benefits.
Central air-conditioning system is a long-term use, high reliability projects, must be reliable long-term operation, to ensure the use of results. In the design and construction of the first consideration is to strictly control the quality and ensure the quality of the project, and in line with relevant national standards and norms, regardless of program design or equipment selection, construction, well drilling and other links must be around This center.

Precautions.
1.Check whether the inspection cycle of acetylene hoses is expired.2.Check whether the acetylene hose body has cracks, bulging, dent deformation, scratches and whether the base splicing welds are cracked and other problems.
3.Check the corrosion of the acetylene hose body, especially check the corrosion of the bottom and side seams of the acetylene bottle carefully.
4.Check whether the acetylene hose and accessories are defective and damaged.
5.Check whether the color of acetylene hose is off and discolored, if the color of the gas cylinder is not correct, check carefully to determine whether it is acetylene hose. If the new bottle should be pumped into vacuum and replenished with acetone. Open the cylinder valve and check whether the inner core and valve stem of the cylinder are intact and not slipping when measuring the residual pressure of gas with the residual pressure table.
