Air to Water - Hot water heat pumps

In recent years, the need to be more energy conscious and environmentally responsible has become increasingly important to us all. As a leading manufacturer of air conditioning systems, Mitsubishi Electric constantly strives to meet and exceed the increasing demands placed on the industry. Through research and development for the future, we proudly introduce our new Air to Water system which uses water as a heating and cooling medium for space heating/cooling and hot water supply applying the heat pump and heat recovery technology.

Features

  • Booster unit provides hot water to a maximum of 70C
  • HEX unit provides 45C in heating and down to 8C in cooling

Key Technologies of Air to Water Series

Air to Water Series making the most of Heat Pump and Heat Recovery Technology

Heat pump and heat recovery technologies are already well known in the air conditioning market and proved to be efficient for cooling and heating. Mitsubishi Electric has now designed Air to Water (ATW) Series utilising the technologies to provide hot water.

Here is an overview of the technology that is used in the ATW system:

Heat Pump Technology

  • Remarkable energy consumption efficiency
  • Generating much larger heat energy than the input energy
  • Heating or cooling operation

Heat Recovery Technology

  • Effective use of waste heat
  • Heating and cooling simultaneous operation

Both technologies, compared to conventional systems of boilers, not only have incredible design flexibility, excellent use of energy and reduce CO2 emissions, there is a further reduction in capital costs. Negating the need for the installation of gas supply entirely, the ATW Series can provide hot water by means of electricity.

Heat Pump

  • Remarkable energy consumption efficiency
  • Generating much larger heat energy than the input energy
  • Heating or cooling operation

From the energy output side, the operation characteristics of a heat pump are different to conventional systems (such as electric/gas/oil boilers or electric heaters). With conventional systems, 1kW of input energy provides less than 1kW of output energy or heat. With a heat pump system, every 1kW of input energy is converted into an average of 2~5 times of output energy or heat by absorbing heat from outdoor air. Also, a heat pump, as its name shows, “pumps up” heat from a low-temperature source, outdoor air, for example, and transfers it at a higher temperature in a building, making it more efficient than conventional boilers and a natural choice for low-cost heating and hot water.

Heat Recovery

  • Effective use of waste heat
  • Heating and cooling simultaneous operation

Heat recovery system can provide an ideal solution when taking a look at the system from an exhaust energy point of view. This is because air conditioning and hot water are used throughout the year and with a heat recovery system, exhausted heat from the indoor unit is diverted to be reused for a different purpose. For example, the waste heat from cooling operation is reused for heating or hot water supply, and wasted heat from the heating operation or hot water supply is reused for cooling operation or cold water supply. The more frequently heating and cooling simultaneous operation is carried out, the higher the energy saving effect becomes.
