Abstract: In addition to the characteristics of environmental protection, geothermal heat pumps have obvious energy saving advantages. This paper introduces the operation cost of geothermal heat pump analysis and management mode of operation, discusses the geothermal heat pump with the current heating mode (centralized boiler room heating, thermal power plant heating, gas boiler room heating, household gas heating), one-time Investment, operating costs for analysis and comparison.

Key words: Circulation pump Pump operation cost

1, the heat pump operating costs In addition to the characteristics of environmental protection, but also has obvious energy-saving advantages, the following geothermal heat pump with the current heating mode (centralized boiler room heating, heat and power plant heating, gas boiler room heating, household gas Heating), one-time investment, operating costs for analysis and comparison.

Among them: the price of 0.5 yuan / (KW.h), natural gas price of 2.0 yuan / m3, coal price of 300 yuan / t, tap water 3.2 yuan / t, hot water (the project to consider recharge, ). Heating time by 145 days / year.

Table 1 for energy consumption, operating costs comparison table. The cost of energy consumption is only the main equipment fuel costs, operating costs, including fuel costs and depreciation costs (equipment depreciation of 20 years). According to the actual situation of the project, geothermal water temperature is high, so the first and last winter can have 95 days to use geothermal water directly after the plate change, do not start the heat pump, the other 50 days to start the heat pump peak heating.

2, ground

Geothermal water extraction costs per tonne of water consumption 1 KW.H calculation, according to 1.5KW.H recharge calculation, electricity 0.5 yuan / KW.H, groundwater extraction and recharge costs in the table below:

3, the system circulation pump and other pump operating costs estimated as: 10KW

Daily: 240KW.H, daily electricity bill: 120 yuan

Heating season total: 34800KW.H, electricity is: 17400 yuan

4, operating personnel wages calculated by two people, each person's monthly salary of 500 yuan, the heating period total wages: 5,000 yuan

Equivalent to each square meter: 8.76 yuan / year, such as heating costs by 18 yuan / ?. Annual calculation of package burning can be profitable 9.24 yuan / year, the annual profit is: 147,840 yuan.

Press 30 yuan /? Charging network fees can be charged 480,000 yuan, plus the first year heating profit 148,000 yuan,

A total of 628,000 yuan in addition to the injection well has basically solved the problem of initial investment.

The actual implementation of the current heating costs can be taken in advance, or 50% of the advance can greatly ease the pressure on the initial investment.

Proposed to implement the method is: the total project will be packaged into about 100 to 1.2 million of the initial investment, business and training center to charge a fee for access to network (as long as less than 6 tons of coal-fired boilers can), network fees and he signed a Using a number of years of agreement (such as 15 years), due to 15 years or so coal-fired boiler should be completely scrapped. Such conditions estimate the user is acceptable.

Even if you do not consider the issue of who should bear the initial investment, operational management can also be used now widely popular way to burn. Initially, the pilot projects of business training centers will have a direct impact on all subsequent users, and once the mode and charges have been established, it will not be easy to make any major adjustments.

For example, Xi'an charges 15.4 yuan / ?. Year, 115 days, Tianjin is 15 yuan / ?. Around 120 days, central heating in Beijing is 24 yuan / year, 130 day. According to Xi'an or Tianjin standards (equivalent to 0.1339 yuan / day, 0.125 yuan / day), Anshan received 18 to 19 yuan / year is well documented.
