Several important links in the design and construction of ground temperature central air-conditioning

As an environmentally friendly and clean energy source, ground-temperature central air-conditioning is gradually being widely used by people. However, only by paying attention to its important links in the design and construction, the ground-temperature central air-conditioning can operate normally and bring good benefits to the society. Next, please let Shanghai Air Conditioning Design introduce the following content specifically for everyone!

There is no difference between the ground temperature central air-conditioning terminal and the traditional central air-conditioning terminal. The main difference lies in the engine room and the water well. In actual use, there are two main problems that are common: the first is the poor recharge effect of the recharge well, and the recharge water overflows from the well; the second is the accumulation of sand in the water source heat pump unit, which affects the cooling and heating effect of the water source heat pump unit.

Several important links in the design and construction of Shanghai air-conditioning

In order to avoid the above problems, we should pay attention to the design and construction, and do the following links:

one. In order to prevent the blockage of the recharge wells and ensure the long-term stable operation of the air conditioning system, the water well pipe network is designed as a double loop, and the outlet and return wells can be switched to each other. The pumping well and the return well are regularly replaced to ensure the filtration layer in the well. It is unblocked and will not be blocked, ensuring the refilling volume and the water output of the well.

two. The sewage pipe must be designed in the water well pipe network. Nowadays, the common construction drawing design generally considers the sewage pipe for the water outlet pipe, which is beneficial to the well washing after the well pipe network is installed, and the newly drilled well is continuously pumped. , Usually around two or three days day and night, in addition, the well should be cleaned every summer and winter when the machine is turned on. Generally, the well can be pumped out in one or two days. After the well water is drained, the main unit and pump can be extended. Waiting for the service life of the equipment, it can avoid pollution of groundwater sources.

three. The well water return pipe and the sewage pipe are connected, and the main engine inlet and outlet pipes plus bypass pipes are helpful to thoroughly clean the impurities in the pipeline. The general designer's idea is that after the well is drained, water is poured into the pipe network, and then the water is discharged from the cyclone desander. After flushing, the drain pipe of the desander is closed and water is poured into the main engine. Disadvantages of this:

1. Only part of the piping system is flushed, and impurities are easy to deposit in the host.

2. Unclean water flowing back into the well can easily cause groundwater pollution.

3. The water flowing out of the cyclone desander is not easy to drain away in time and spreads in the machine room. Especially when the machine room is located in the basement, the flow rate of the sewage pump is often only a few tons per hour, while the water output of the deep well pump is less than tens of tons or even one or two hundred tons per hour.

Geothermal central air-conditioning is an energy-saving air-conditioning system that utilizes shallow underground geothermal resources to provide both heat and cooling. The water source heat pump realizes the transfer of heat energy from low temperature to high temperature by inputting a small amount of high-grade energy.
