Application
A. Application of the conditions of groundwater source heat pump system
1. Rich water near the building, facilitate the implementatiom of the supply and return water
2. Local policy allows using groundwater
3. Groundwater temperature appropriate, the water is suitable, water supply stability, water return smoothly
B. Application of the conditions of the surface water source heat pump system
1. Rich water near the building ( such as river, lake water, seawater, reservoir water, industrialwastewater and so on)
2. Adequate water, moderate temperature, the water can meet the using requirements after simple handling.
C. Pplication of the conditions of ground source heat heat pump system
1. Lake of water near the building or various factors limit use of water resource
2. There is enough space around the building for the ground-couple system.
Advantages
1. High Reliability
Using famous parts, and as the temperature of the original source is stable, the water/ground source heat pump works more reliable and stable, guaranteeing the high efficiency and economy. Without problem of defrosting in winter.
2. One Unit for Multi-usage and Wide Application
It could be used for cooling, heating and tap hot water for daily life, one unit for multi-usage.
3. High Efficiency for Heat Recovery
Using the latest high technology, following the law of conservation, when the unit is cooling, the heat recovers to produce the hot water (for example, in summer, it provides the free hot water by heat recovery). The unit is with higher efficiency and more energy saving.
4. Less Cost
The working condition is reliable, so the system is simple and less components. It runs easily and reliably, and maintenance cost is less.
5. Environment Friendly
Use R410A refrigerant, the ratio of ozonosphere damage is zero, environment friendly, green product, meet the countries' environmental protection demand.
