6 STEPS – gEOTHERMAL SYSTEM
1. Solar Collector Banking: Solar collectors are devices that capture sunlight and convert it into heat or electricity. Solar collector banking may refer to storing excess energy generated by solar collectors for later use.
2. Trench Collectors:Trench collectors in the context of geothermal energy involve burying pipes or heat exchangers in the ground to capture the Earth?s natural heat.
3. Vertical Collector: Vertical energy collectors are systems that extract geothermal heat vertically from the ground, typically using boreholes.
4. Spiral Energy Accumulation: Spiral energy accumulation refer to a design where energy is collected and stored in a spiral configuration, in the context of a heat exchanger or storage system.
5. Energy Manifold for U-Tube System: In a geothermal or solar heating system, a manifold is a device that distributes or collects fluid (usually water or a heat-transfer fluid). A U-tube system refer to a configuration where pipes are shaped like a U for efficient heat exchange.
6. Commercial Heat Pump System: Commercial heat pump systems use electricity to move heat from a lower temperature source (e.g., the ground or air) to a higher temperature space (e.g., a building). This process is efficient for both heating and cooling.
gEOTHERMAL SYSTEM
A geothermal system, also known as a geothermal heat pump system or ground source heat pump system, is a type of heating, ventilation, and air conditioning (HVAC) system that uses the earth’s natural heat to provide heating, cooling, and hot water for residential, commercial, and industrial buildings. Here’s how it works:
A geothermal system, also known as a geothermal heat pump system or ground source heat pump system, is a type of heating, ventilation, and air conditioning (HVAC) system that uses the earth’s natural heat to provide heating, cooling, and hot water for residential, commercial, and industrial buildings. Here’s how it works:
- Heat Exchange: Unlike conventional HVAC systems that rely on air or water as the heat exchange medium, geothermal systems transfer heat to and from the ground. The earth’s surface maintains a relatively constant temperature throughout the year, typically between 50?F to 60?F (10?C to 15.5?C) depending on the location and depth.
- Heat Pump Unit: The geothermal heat pump unit is the central component of the system. It consists of a compressor, condenser, evaporator, and refrigerant circulating system. During the heating mode, the heat pump extracts heat from the ground and transfers it to the building’s interior. In the cooling mode, it removes heat from the building and dissipates it into the ground.
- Ground Loop System: The heat exchange with the ground is facilitated by a network of underground pipes called a ground loop system. There are different types of ground loop configurations, including horizontal loops, vertical boreholes, and pond/lake loops, depending on site conditions and available space.
- Horizontal Loops: These are installed in trenches dug horizontally in the ground. They are suitable for properties with ample land area.
- Vertical Boreholes: Vertical loops involve drilling boreholes vertically into the ground and inserting the pipes. They are used when space is limited or soil conditions are not suitable for horizontal loops.
- Pond/Lake Loops: If a property has a nearby body of water such as a pond or lake, coils of pipe can be submerged to extract or dissipate heat.
- Distribution System: Geothermal systems can utilize ductwork for forced air distribution or radiant heating/cooling systems for delivering heat or cooling directly to the building’s interior spaces.
Benefits of geothermal systems include:
Energy Efficiency:
Geothermal systems can be highly efficient, with heating efficiencies 50% to 70% higher than traditional furnaces and cooling efficiencies 20% to 40% higher than conventional air conditioners.
Reliability:
They produce lower greenhouse gas emissions compared to fossil fuel-based heating systems, contributing to reduced carbon footprint.
Environmental Benefits:
Geothermal systems are durable and have long lifespans, often exceeding 20 years for the heat pump unit and 50 years for the ground loop system.
Cost Savings:
Although initial installation costs may be higher than conventional systems, geothermal systems offer long-term energy savings, potentially offsetting the upfront investment over time.
GEOTHERMAL UNITS
Geothermal units, also known as geothermal heat pumps or ground source heat pumps, are the central components of geothermal heating and cooling systems. These units utilize the earth’s relatively constant temperature to efficiently heat and cool buildings. There are two main types of geothermal units:
Water-to-Air Geothermal Heat Pumps:
These units transfer heat between the ground loop system and the building’s air distribution system.
During the heating mode, they extract heat from the ground loop and distribute it as warm air through ductwork or radiant heating systems.
In the cooling mode, they remove heat from the indoor air and transfer it to the ground loop for dissipation.
Water-to-air heat pumps are suitable for buildings with forced-air heating and cooling systems.
Water-to-Water Geothermal Heat Pumps:
The units facilitate the exchange of heat between the ground loop system and a hydronic (water-based) distribution network. In heating mode, they draw heat from the ground loop and distribute it through pipes to radiators, underfloor heating systems, or fan coils. When operating in cooling mode, they absorb heat from the building’s hydronic system and transfer it back into the ground loop. Water-to-water heat pumps are particularly suitable for buildings equipped with radiant floor heating or hydronic fan coil units.
Both types of geothermal units consist of several key components:
- Compressor: The compressor pressurizes the refrigerant, enabling it to absorb and release heat efficiently.
- Condenser: In heating mode, the condenser releases heat to the building’s distribution system. In cooling mode, it absorbs heat from the indoor air or hydronic system.
- Evaporator: In heating mode, the evaporator absorbs heat from the ground loop. In cooling mode, it releases heat to the ground loop.
- Refrigerant Circulating System: This system circulates refrigerant between the compressor, condenser, and evaporator, facilitating heat transfer.
- Control System: The control system regulates the operation of the unit, monitoring temperature and system performance to optimize efficiency and comfort.
HYBRID SYSTEM
CLAUSIUS ground source heat pumps can be used in hybrid geothermal-aerothermal systems, in which both a ground collector and an air collector are used simultaneously and integrated in the same installation. Hybrid systems allow to obtain the advantages of both energy collection systems and avoid their major drawbacks, which are the low efficiency of the air systems at low outside temperatures and the high cost of the ground collectors.
The heat pumps incorporate a specific control for hybrid systems. The control system choose the operating conditions that provide maximum possible energy efficiency by an optimum glycol flow distribution between the ground and the air collectors, obtaining the maximum efficiency of the heating and cooling system at all times.
BUILT-IN DESUPERHEATER IN CLASSIC MODELS
In CLASSIC configuration and in all H and HC models, a system with desuperheater can be integrated.
The system with desuperheater allows the production of DHW at high temperature as well as a simultaneous production of heating and DHW or swimming pool and cooling with DHW or swimming pool in HC DS models. The desuperheater system consists of one heat exchanger (desuperheater), a circulation pump and the corresponding valves and control system. Our desuperheater system allows:
- Simultaneous production of heating and DHW at high temperature.
- Simultaneous production of cooling and DHW at high temperature.
- Simultaneous production of heating and swimming pool.
- Simultaneous production of cooling and swimming pool.
- Production of only DHW using the condenser and desuperheater simultaneously, which increases the efficiency of the heat pump in these processes
DHW TANKS WITH BUILT-IN DESUPERHEATER IN CLASSIC MODELS
In CLASSIC configuration, all H and HC models can be combined with a DHW tank with desuperheater to produce DHW at high temperature. Combination of CLASSIC models with DHW tank with desuperheater allows DHW production at temperatures up to 80 ?C without electric heaters.
CLASSIC models combined with DHW tanks with desuperheater include all connection and control elements of the DHW production system and are supplied preloaded with refrigerant and with quick connections. The capacities of CLAUSIUS DHW tanks with desuperheater available are 250, 300 and 500 liters. The use of these tanks enables to considerably increase the amount of DHW available. The use of a 500 liters tank with DHW at 80 ?C would allow to obtain more than 1000 liters of DHW for domestic use at 38 ?C.
