Basic Knowledge from One of the Geothermal HVAC Manufacturers - Fantastic™ Heat Pump China
According to relevant historical records, geothermal HVAC systems have been installed and used all around the world for more than 60 years. They are able to heat or cool a house or a whole commercial building with the advantage of not burning any fuel or releasing any greenhouse gases.
In many countries in Europe, geothermal heating and cooling are common. For example, in Switzerland and Sweden, more than 75% new houses have geothermal. More and more countries now have already recognized that geothermal HVAC systems are the most environmental friendly, the most energy efficient, and the most cost-effective HVAC systems available currently.
For geothermal heat pump systems, different geothermal HVAC manufacturers including Fantastic™ heat pump china have different name for geothermal heating and cooling such as Geothermal, Ground Source Heating and Cooling, or Water Source Heating and Cooling. But they all refer to exactly the same thing, so please do not be confused by these different names. But it's important to mention that it's not about using the heat drawn from the core of the earth to generate electricity, but about using the crust of the earth to heat or cool a house or a commercial building.
During winter operation, water circulates through the underground pipes, or also called the ground loop, and absorbs the heat of the earth before returning indoor to the heat pump. The heat pump draws the heat from the ground loop water and then distributes it as warm air throughout the house. The ground loop water will recirculated with the heat removed in order to collect more heat from the earth. Therefore, the ground loop water becomes warmer when it circulates into the house.
On the contrary, during summer operation, the heat pump draws the heat from the house and removes the heat to the ground loop water and make the air in the house cool by distributing through vents or fan coils just like air conditioner. And then the heat removed from the air will be delivered to the earth through ground loop water. Therefore, the ground loop water becomes cooler when it circulates into the house.
As one of the professional geothermal HVAC manufacturers, Fantastic™ heat pump china also would like to share some knowledge for sizing a geothermal heat pump. Geothermal heat pump size varies and it depends on the size of the house or the size of the commercial building. To determined how large of a heat pump is needed for your house, there are several factors that needs to be considered. Because to size a geothermal heat pump is a complicated process, it's better to contact a qualified geothermal heat pump professional who is able to work on an energy analysis about the house's or the building's heating or cooling demand which allows them to calculate the right size for the system. The size of the ground loop will be dictated by the size of the system. An experienced engineer knows how to design the system accurately in order to lower the operating costs and ensure the long service life of the system.
