EnergyIntel's Advanced Residential Solution includes the following subsystems :
DescriptionThe solution combines all the above systems to provide an efficient and energy saving heating and cooling system for your residence. Space Heating
The space heating is supported by a perfect designed and high quality water flow floor heating system. The floor heating is supplied with hot water primary by a SONNENKRAFT solar thermal system, which produces a large amount of hot water using the solar energy, and secondly by an electrical Heat Pump Chiller. The Heat Pump Chiller is a highly efficient (COP more than 3.5) electrically generated chiller, which has the ability to produce both hot and cold water. Domestic Hot Water
The domestic use hot water is produced mainly by the SONNENKRAFT solar thermal system (more than 85%) and secondly by the Heat Pump Chiller. Space Cooling
The space cooling is supported by a water flow floor cooling system and some strategically placed fan coil units (FCU). Both systems are supplied with cold water by the Heat Pump Chiller. The floor cooling system drops the space temperature significantly by cooling the floor and the air above it, while the fan coil units remove the hot air from the room, enabling the cold air to rise from the floor and move upwards and also dehumidify the area. Moreover the fan coil units, release cold air into the room and help the floor cooling system to provide you a cool comfort environment. Benefits
The benefits of using the Advanced Residential Solution are the following : - Comfort environment for the winter and the summer
- Low energy cost for heating and cooling
Technical InformationHeat Pump Chiller
Heat pumps work by circulating a working fluid, or refrigerant, which vaporizes at a low temperature (in the evaporator), producing additional energy in the process. A compressor further concentrates the warmed vapor, raising it to a temperature where it can be circulated through an air handler and used for heating. When the cycle reverses, heat is pumped from indoors to out, as with standard air conditioners (in Canada heat pumps are known as "reverse cycle air conditioners") Traditionally, heat pumps have been sized to cooling loads and used where outdoor temperatures rarely fall below freezing. As outdoor temperatures drop, there is less heat available for efficient extraction by the evaporator, and supplemental heat may need to be provided by electric resistance strips. To protect the evaporator from freeze damage, it must occasionally run in a defrost cycle where the flow of refrigerant is reversed, so that heat from the interior of the house will melt accumulated ice deposits in the outdoor coil. This results in uncomfortably cold air being circulated throughout the home during the cycle, a common source of frustration and complaint among heat pump owners. Fan Coil Units
A fan coil unit (FCU) is a simple device consisting of a heating or cooling coil and fan. It is part of an HVAC system found in residential, commercial, and industrial buildings. Since it does not have any ductwork, a fan coil unit is used to control the temperature only in the space where it is installed. It is controlled either by a manual on/off switch or by thermostat.Due to their simplicity, fan coil units are more economic to install than ducted or central heating systems.
The coil receives hot or cold water from a central plant, and removes or adds heat from the air through heat transfer. Fan coil units can contain their own internal thermostat, or can be wired to operate with a remote thermostat.
Fan coil units circulate hot or cold water through a coil in order to condition a space. The unit gets its hot or cold water from a central plant, or mechanical room containing equipment for removing heat from the central building's closed-loop. The equipment used can consist of machines used to remove heat such as a chiller or a cooling tower and equipment for adding heat to the building's water such as a boiler or a commercial water heater. |
