Introduction
Daikin air to water refers to a ground-breaking technology that Daikin has pioneered in its air-to-water heat pump products. This technology is provided in both the Daikin Altherma and Daikin FACP, and both are revolutionary because of their ability to provide warm water, hot water, or chilled water.
What is Air-to-Water?
Air-to-water systems use an air-to-water heat pump that takes air as the energy source instead of fossil fuels such as natural gas or electricity. The Daikin air to water heat pump unit is installed outdoors and uses the outdoor air as the energy source, producing high-quality indoor air in addition to providing hot water.
Air-to-water systems can be used for heating and cooling, and for providing hot water or even chilled water. Typical uses of an air-to-water system are:
They can be used to replace an existing fossil fuel boiler such as natural gas, propane, or oil.
By providing the air-conditioning and heating system with an air-to-water heat pump instead of a fossil fuel boiler, an air-to-water system can be more environmentally friendly. A fossil fuel boiler releases greenhouse gases into the environment which contribute to global warming but a heat pump does not. In addition, because of the energy efficiency of an air-to-water system, it is usually more cost-effective than other home heating/cooling systems.
How does Air-to-Water Work?
A Daikin air-to-water system consists of an air-to-water heat pump, a control system, and a pre-conditioning unit. The air-to-water heat pump is installed outdoors, where the outdoor air can enter the heat pump unit through a “chimney” or “vent”. The heat pump uses this outside atmospheric air as the energy source or fuel. The heat is extracted from the air and transferred to a refrigeration circuit (the refrigerant) where it is further expanded. Since the refrigerant is at a low temperature (compared to the air), it absorbs heat from the cooling cycle, making it hot. This hot refrigerant then enters an expansion valve where it cools down, allowing it to enter the heating cycle once again. This cycle is repeated until work output has been created to provide either hot water or chilled water or both.
The control system of a Daikin air-to-water system controls the heat pump unit, keeps track of energy consumption, and regulates the temperature of both the indoor air and the refrigerant. It also monitors compressor oil temperature as well as compressor motor speed to perform maintenance on these components.
The pre-conditioning unit is an enclosure that contains a water pump, which is used to produce hot water or chilled water. The pre-conditioning unit can be installed indoors, where it works, and alongside the heat pump.
The Daikin air to water heat pump unit is typically installed outdoors. The outdoor air enters the heat pump unit through a chimney or a vent, which then heats up in the process of being cooled. From this warm environment, hot water and/or chilled water are extracted. The Daikin FACP can be mounted indoors where it functions as an indoor condensing unit just like a gas-fired heating system would.
Conclusion
The Daikin altherma and Daikin FACP are revolutionary products that supply warm water, hot water, or chilled water. These products operate in environmentally friendly ways, and because of their energy efficiency are typically more cost-effective than other systems. Daikin air to water technology is a ground-breaking technology that uses a heat pump to provide hot water or chilled water instead of using fossil fuels such as natural gas or electricity.
