Advantages and disadvantages of ground source heat pump in heat pump School
Heat pump technology is a new energy technology that has attracted much attention in the world in recent years.
Ground source heat pump is one of the heat pumps and has become a leader in the 'coal reform' project. So, what are the advantages and disadvantages of ground source heat pumps?
The following is an introduction to the advantages and disadvantages of ground source heat pump: the advantages of environment and economic benefits are remarkable. When the ground source heat pump unit is running, it does not consume water or pollute water, does not need boilers, and does not need cooling towers, there is no need to pile up fuel waste sites, and the environmental benefits are remarkable.
The power consumption of ground source heat pump unit can also be reduced by more than 40% compared with air source heat pump;
Compared with electric heating, it can be reduced by more than 70%, and its heating system improves the efficiency of gas-fired boilers by nearly 50% on average and 75% higher than that of gas-fired boilers.
One machine is multi-purpose and widely used. The ground source heat pump system can provide heating, air conditioning and refrigeration, and can also provide domestic hot water. One machine is multi-purpose, which not only saves a lot of energy, moreover, one set of equipment can meet the requirements of heating, cooling and domestic water supply at the same time, thus reducing the initial investment of the equipment, ground source heat pump can be applied to hotels, residential quarters, apartments, factories, shopping malls, office buildings, schools and other buildings. Small ground source heat pump is more suitable for heating and air conditioning of villa houses.
The pollutant emission of polluted small ground source heat pump is equivalent to a reduction of more than 38% compared with air source heat pump and more than 70% compared with electric heating, the real realization of energy conservation and emission reduction is to reduce energy waste and reduce exhaust emissions more.
Space saving, no cooling tower, boiler room and other equipment, eliminating the precious area occupied by boiler room and cooling tower, generating additional economic benefits and improving the external image of the environment.
Disadvantages: the soil heat is unbalanced. The southern region is dominated by cooling and injects heat into the ground all the year round;
However, the demand for heating in winter in the northern region is large, and a large amount of heat is absorbed from the soil. After long-term operation, the soil temperature will be unbalanced, the system efficiency will be reduced, and the surrounding ecology will be affected.
The application of ground source heat pump with limited application will be affected by energy policies and fuel prices of different regions, different users and countries;
One-time investment and operating costs will vary with different users;
The utilization of groundwater will be restricted by local groundwater resources;
Well drilling and buried pipes are relatively limited by the site, and there must be enough area for well drilling and buried pipes;
In the design and operation, there are great requirements for the annual cold and heat balance, and the Heat discharged from the underground in summer and the heat taken from the underground in winter should be roughly balanced.
The energy of ground source heat pump system comes from natural energy.
It does not discharge any waste gas, waste water and waste residue to the outside world, and is an ideal 'green air conditioner '.
It is considered to be an environmentally friendly and effective heating and cooling system currently available.
The system can be used in severe cold areas or tropical areas.
Can be widely used in office buildings, hotels, schools, dormitories, hospitals, restaurants, shopping malls, villas, residential and other fields.
