Other considerations:
If the green area or parking area is relatively large, we can consider the source, because the source needs a larger area to do burial pipe. Conversely, consider water source heat pump. Moreover, the cost of ground source well drilling is much higher than that of water source, and some geological conditions are not suitable for ground source heat pump, so it is too difficult to drill well.
E. the difference between pumps:
No matter water source or ground source: generally two sets of pumps, one for the unit to provide cooling and heating load of the water supply pump, one for the end of the water supply air conditioning pump
Ground source heat pump mainly uses pipeline centrifugal pump to select pump according to water temperature! Vertical centrifugal pumps are also called pipeline pumps. Ground source heat pumps (GSHPS) are commonly used in ground source heat pumps. Submersible pump ground source heat pumps (GSHPS) for groundwater source heat pumps (GSHPS) are air conditioning systems, including cold and heat sources and terminal parts of the engine room, and the terminal part is the same as conventional air conditioning.
The machine room part includes the main engine, water pump, water collector, buried pipe, repair well, perhaps if the heat and cold are unbalanced, cooling tower or plate replacement should be used.
Installation is in accordance with the construction drawings and construction specifications. There are professional well drilling companies in the buried part. The horizontal buried pipe and the vertical buried pipe can be done.
Large projects or small villas, the two types of computer room part is different.
A / At present, there are two types of compressors for ground source heat pump mainframe on the market, one is the fully enclosed unit of scroll compressor, the other is the semi-enclosed unit of screw compressor. The installation of the two main equipment is different.
1) The main engine of the scroll ground source heat pump is equipped with four-way reversing valve. Its evaporator and condenser will switch automatically under the condition of refrigeration and heating. Therefore, the water side pipeline of the main engine does not need to do pipeline switching. It can be connected directly according to the standard load side and source side. Of course, all the water side of air conditioning needs water pumps.
2) The main engine of screw-type ground source heat pump has no built-in four-way reversing valve, so the chilled water side of the main engine must be switched well. In the case of refrigeration and heating, the functions of evaporator and condenser are interchangeable. In summer, the evaporator is connected to the load side, while in winter, the condenser is connected to the load side.
B / Design is not for you, but the design of the outdoor buried pipe of ground source heat pump is very important. If you have drawings, just follow the drawings. The construction outsourcing of buried pipes is enough. But we must control it well, because many drilling teams are fooling around now. When you finish, it's too late to find problems when you run. There are several points for reference:
