Ground source heat pump cost
The initial investment of ordinary central air-conditioning includes the
main engine, terminal costs, and installation costs, while ground source heat
pumps have more costs for drilling wells. For buried pipes, there are corresponding
costs for pipes and well fillers. Therefore, domestic ground sources The price
of heat pumps is higher than that of ordinary central air conditioners.
For ground source heat pumps, I believe that people will often be
entangled in the initial installation cost when choosing to use it. So how can
I have a rough calculation of the initial installation cost, and what are the
costs? Let's make a preliminary calculation of the installation costs of using
ground source heat pumps.
The initial installation cost of ground source heat pumps should also be
calculated according to the size of the used area. Therefore, the price of
domestic ground source heat pumps is greatly affected by the residential area.
Generally, the larger the villa area, the higher the price of ground source
heat pumps. At the same time, compared with ordinary central air conditioners,
the initial investment of ground source heat pumps is much higher, but users do
not need to worry about this. Because the ground source heat pump is an air
conditioning system with high investment and high return rate. The ground
source heat pump saves energy by about 40% on average than the central air
conditioner. The extra cost at the initial investment can be saved through
electricity bills in a few years. The service life is as long as 25 years,
which is twice that of ordinary central air conditioners.
First of all, the cost of the whole ground source heat pump system
includes two points, namely the unit system and the construction system. The cost
of the unit is mainly affected by the application area, the demand for heat and
cold of the building, the operating power, the brand and other factors.
Relatively speaking, it is easier to calculate, and the investment of ground
source heat pump construction funds is quite different. If the ground source
heat pump uses horizontal buried pipes, the cost will be relatively low, while
the cost of vertical buried pipes will be higher. On the other hand, the soil
quality of the construction site will also have a certain impact on the cost of
underground well drilling. The depth of the buried pipe is also a relatively
important factor.
Although there are many factors influencing the cost of ground source
heat pumps, when choosing a unit manufacturer and buried pipe construction
team, you must not be greedy for cheap. As the saying goes, you get what you
pay for. Due to the influence of the industry, there are many ground source
heat pump manufacturers. Market competition has started price wars, and the
price wars have a greater impact on the quality of the unit products, so good
quality products are not particularly cheap, so users must not be greedy for
temporary cheapness when choosing. And affect the later use.
So how to solve this problem? Although the soil heat balance of ground
source heat pumps can have a greater impact, these problems can be avoided as
long as they are handled properly. Through the underground heat exchanger and
the ground source heat pump, the unit is set into multiple circuits in turn for
use. If the conditions are partially met, the peripheral circuit arranged by
the soil heat exchanger is selected first to extend the temperature recovery of
the soil heat exchanger and avoid localization. overheat.
In addition, the cooling system can be used as an auxiliary for projects with large differences in soil heat load in summer, and the heat recovery technology of heat pump units can be used to reduce the heat output in summer and avoid excessive heat load, thereby solving the problem of heat balance. There is also a temperature sensor that can be installed to detect the soil temperature in winter and summer in a timely manner. When the temperature is too high, a peak shaving system should be used.
