Geothermal Heat Pump Project

134a in this system can repeatedly carry out both evaporation endothermic and condensation exothermic physical phase transition process. In this way, the heat exchange, delivery and transfer in space can be realized.

3. Central Air Conditioning System of Geothermal Heat Pump

The central air conditioning system of geothermal heat pump adopts the rock and soil mass, groundwater or surface water as its low temperature heat sources. It is composed of the water source heat pump system, geothermal energy exchange system, as well as the internal building system.

Working Principle

In winter, the heat pump system absorbs heat from the ground sources, such as swallow water or the rock and soil mass, to supply heating to buildings. In summer, this heat pump system can absorb heat from the room and then transfer and release it into the ground sources, which can achieve the air conditioning refrigeration of buildings. In accordance with different forms of the ground source exchange system, the geothermal heat pump system can be classified as the groundwater type, surface water type and the buried pipe type.

Application Conditions

1. Groundwater Geothermal Heat Pump System

Firstly, the groundwater resources nearby the construction project should be abundant and convenient to carry out the water supply and return engineering. Next, the local policy allows using groundwater. Other application conditions include moderate groundwater temperature, appropriate water quality, stable water supply, as well as smooth recharge to groundwater.

2. Surface Water Geothermal Heat Pump System

Near the construction project, there is rich surface water, such as river, lake, ocean, reservoir, sewage, reclaimed water, geothermal tail water, industrial waste water and so on. Water must be sufficient and the water temperature is moderate. After simple treatment, the water quality can meet the operating requirements.

3. Buried Pipe Heat Pump System

First of all, water resources are insufficient near the buildings, or the water resources can not be used due to all kinds of limiting factors. Next, there should be enough site near the buildings for burying pipes, such as villas, gardens, school playground, the site in front of or behind the office building and some others.

Design Philosophy

The design philosophy of geothermal heat pump includes environmental protection, energy and water reduction, as well as customer satisfaction. The water source heat pump utilizes the solar energy resource stored in the surface soil and water as its cold and heat sources. It prominently features no combustion, smoke evacuation, garbage or pollution, which adopts renewable resources for environmental protection. With the progressive design, this product possesses high energy efficiency ratio of above 4.0 for heating and more than 5.0 for cooling, and the highest energy efficiency ratio can reach up to 7.1. Moreover, the heat exchanger is designed with small flow and large temperature difference. Our system is able to consume 40% less water than the traditional product. This set of system can meet the needs for both cooling and heating effects, which only requires a half to two thirds less investment and operating cost than the conventional type.

Thanks to the entirely independent modular design of subsystem, this geothermal heat pump can provide small number of components, superior quality, and various types of security functions. It takes full account of the coordinated control of multiple systems, which can achieve the computer remote control to make system more humanized and intelligent.

Air Source Heat Pump Technology

1. Air source heat pump technology is energy saving and eco friendly heating type based on the reverse Carnot cycle principle. The air source heat pump system depends on the natural energy to obtain the low temperature heat source. After being integrated efficiently, the high temperature heat source is formed for heating or hot water supply. The entire system possesses extremely high heat collecting efficiency.

2. This geothermal heat pump owns four remarkable advantages. The first two advantages are energy conservation and environmental protection. In addition, our pump combines heating with cooling, which makes high utilization rate of equipment and significant cost reduction. Finally, it is driven by electricity, so it is very convenient to regulate and control it. This heat pump is well received by our customers.

3. This heat pump is able to improve the utilization of energy efficiency. In terms of the environment, it can reduce the green house gas emissions. Moreover, it has effectively solved the problem of upper air electric load.

4. By adoption of the reverse Carnot principle, our geothermal heat pump only requires a little electric power to absorb much low temperature heat energy from the air. Through the compressor, it becomes high temperature heat energy to be transported to the water tank. Then, hot water is heated. Therefore, this pump is characterized by low energy consumption, high efficiency, fast speed, great security and wonderful environmental protection, which can provide hot water continuously. As hot water system, it owns numerous incomparable advantages.

5. The heat pump hot water system abides by both energy conservation law and the second law of thermodynamics. By adoption of the principle of heat pump, it only consumes a small part of mechanical work to transfer the heat at low temperature to the water heater at high temperature. In this way, high temperature hot water can be produced.

As we all know, water can not spontaneously flow from the lower to the higher place. It needs a water pump that can consume some electric power to transport water to the higher water tank. Similarly, according to the second law of thermodynamics, heat also requires a machine that consumes some mechanical work like electric power so as to send the heat under low temperature environment to the high temperature environment. This kind of machine is called heat pump. The heat pump serves to pump the heat from air or low temperature water and then convert all electric power into heat energy to be used in high temperature environment.
