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.
