Pipeline advantages

1. Energy saving and high efficiency

The ground source heat pump system is a new air conditioning technology that uses geothermal energy, a renewable energy source advocated and promoted internationally, as a cold and hot source to heat and cool buildings and provide domestic hot water. It is 2-3 meters below the ground and maintains a constant temperature ( 10-15 ℃ ) all year round, which is much higher than the outdoor temperature in winter. Therefore, the ground source heat pump uses the heat pump to increase the low-level heat energy in the earth to heat the building in winter; in summer, the heat pump transfers the heat in the building to the ground to cool the building. The energy efficiency ratio of the boiler system (energy efficiency ratio = output energy / input energy) is only about 0.9 , the energy efficiency ratio of ordinary central air conditioning is about 2.5 , and the energy efficiency ratio of the energy heat pump system can reach more than 4.0 . The energy utilization efficiency is doubled.

2. Green, environmentally friendly and pollution-free

When the ground source heat pump system is used for heating in winter, it does not require a boiler and does not emit combustion products, which can significantly reduce the emission of room temperature gases, thus protecting the environment and complying with the Global Climate Convention. When cooling in summer, the heat is also transferred to the ground, and no hot river gases are emitted into the atmosphere. If it is widely used, it will greatly reduce the room temperature effect and slow down the process of global warming.

3. Renewable energy, never exhausted

The ground source heat pump system removes heat from or discharges heat to the shallow normal temperature soil. The heat energy of the shallow soil comes from solar energy, which is never exhausted and is a renewable energy source. Therefore, when using the ground source heat pump system, the soil heat source can be replenished by itself. Continuous use is not inferior to the problem of resource depletion. In addition, the soil has good heat storage performance. In winter, the heat pump can cool down the low-level thermal energy buildings in the earth, and store heat for winter use, ensuring the balance of the earth’s heat.

4. Stable operating conditions

The ground temperature is stable all year round and is not affected by the atmospheric environment, allowing the heat pump to operate efficiently whether in heating or cooling.

5. Lowoperating costs

The heating and cooling costs of a ground source heat pump system are only 30-70% of the costs of ordinary heating and cooling technologies .

6. Low maintenance fee

The ground source heat pump system does not have outdoor installed equipment, no cooling tower, roof fan, and no outdoor equipment installation and maintenance costs.

7. Longer service life

The service life of the units is more than 20 years, and the service life of the underground pipe heat exchange system and closed surface water heat exchange system can reach 50 years.

8. Save space

It eliminates the need for cooling towers and boiler rooms and the supporting coal yards and slag yards, saves land resources, generates additional economic benefits, and improves the external environment of the building.

9. Safe and reliable

There is no combustion equipment, so there is no hidden danger of explosion or combustion.

energy technology

The ground source heat pump system is a cooling and heating air conditioning and domestic hot water system that uses rock, groundwater or the ground as the main low-temperature heat source , and is composed of a water source heat pump unit, a geothermal energy exchange system, and a system within a building. According to the different forms of the geothermal heat exchange system, the ground source heat pump system is divided into a buried pipe ground source heat pump system, a groundwater ground source heat pump system, and a surface water ground source heat pump system.

Underground pipe heat exchange system

A low-energy exchange system in which the heat transfer medium exchanges heat with the rock and soil through vertical or horizontal buried tube heat exchangers, also known as soil heat exchange system.

1. Horizontal ground heat exchange system (horizontal ground heat system )
2. Verticalground heat system

Groundwater heat exchange system

A geothermal energy exchange system in which groundwater is pumped out and returned to the same underground aquifer after heat exchange .

Surface water heat exchange system

Geothermal energy exchange systems that exchange heat with surface water are divided into open surface water heat exchange systems and closed surface water heat exchange systems.

1. Opensurface water heat exchange system

( open-loop surface water system )

2. Closed surface water heat exchange system

( closed-loop surface water system )
