Information

Responsibility and energy saving


Energy is an important topic-both in the medium and long term. In order to prevent climate warming, energy consumption around the world must be quickly reduced. Relevant policies have been formulated. Especially in terms of RLT equipment, there is huge space saving. There were already technical solutions long ago.


The green KV system was developed based on economic principles. Internal quality standards help it operate more efficiently.


The minimum pressure loss (about 150-250 Pa per wind direction) is
based on the best cleanliness of VDI 3803, through a high-quality, particularly stable sheet design. The
power structure model has been certified (South German T?V)
integrated filter pre Thermal (VDI 6022)


Hydraulic module


The use of high-quality materials and energy-saving technologies—combined with our professional engineering knowledge—improves efficiency.


75% dry heat recovery, even more internal dehumidification to recover cold air under secondary WRG heat recovery conditions

Multifunctional system for WRG heat recovery, KRG cold air recovery, heating, cooling, dehumidification
through exhaust air Cold air recovery by humidification has always been integrated. During
dehumidification, the necessary secondary heating furnace can be connected to heat recovery to use energy for free.
Heat recovery does not reach 100%, but heat or cold air can be added to the hydraulic module: no It will cause extra pressure loss and energy loss in RLT equipment.

Understand how the system works


The controller is the intelligence of the system. The green KV system optimizes each process and coordinates the operating status between components. In this way, efficiency is optimized-the system efficiency at every point in time tells everything.


Real-time data recording and processing: what the system is running, when and how much energy is saved, and whether all components are operating normally, you can track the above information on the analysis tools equipped with it.

 

 

The Need for Energy Saving


HVAC systems are significant energy consumers globally, and the proportion of energy consumption continues to grow each year as the global economy continues to develop and the volume of indoor air conditioned spaces grows.

 

The general degradation of outdoor air quality as well as the trend of warmer global temperatures and hotter summers will force this trend even more, causing a rapidly acclerating energy demand from global HVAC systems.

 

This places an important responsibility of designers of HVAC systems to explore and implement methods of achieving the indoor comfort and safety needs of people around the world with minimum burden to the environment.

 

What are Run-Around Coil Systems?


Run-around coil systems are one technology that can be implemented on the air-side of industrial and commercial HVAC systems to reduce the energy consumption of the system.

 

Run-around coil systems reduce energy demand by recovering energy in the form of waste heat or waste cold from exhaust air streams. This energy is then used to pre-condition the building's fresh air supply, achieving significant reduction of the fresh air processing energy demand.

 

Run-around coil systems function by placing air-to-water heat exchangers in both the exhaust and fresh air streams. A circulating heat transfer fluid (normally pure water) is used to transport the energy from one air stream to the other. The water flow is controlled by a central Hydraulic Module which continuously monitors and optimises the energy recovery.


Benefits


By implementing a run-around coil system within a facility's HVAC system, end users can enjoy the following benefits:

  • Reduced cooling demand during warm/summer months
  • Reduced heating demand during cold/winter months
  • Typical reduction in air-side energy consumption of 30-35% (depending on overall system design)
  • Improved building energy efficiency performance, future-ready for increasingly strict performance regulations
  • Accurate energy recovery monitoring and flexible data display solutions

System Features

HUBER & RANNER's run-around coil systems are among the most advanced in the world. Our packages incorporate a wide variety of advanced technology, both hardware and software, that ensure a high-performance solution.

  • Ultra-high efficiency full counterflow coils
  • Advanced control algorithms to achieve overall maximum energy recovery
  • Up to 75% temperature efficiency
  • High quality components built to last
 

Intelligent Control


The controller within the hydraulic module is the intelligent brains of the system. The control, through a network of precision sensors within both the hydraulic module and the connected AHU's, constantly monitors the energy being recovered by the system. The controller cna seamlessly switch between summer and winter modes depending on outdoor conditions, as well as intelligently respond to periods where there is limited potential for energy recovery and it is more efficient to turn off the system temporarily (such as night-time low-demand periods or transition seasons where indoor and outdoor temperatures are similar).

 

The controller also monitors the system performance and can identify and alert the operator to potential issues affecting energy recovery performance, such as a fouling heat exchanger or insufficient piping insulation.

 

Applications

 

While our run-around coil solution can be applied to almost any HVAC system, it achieves its best performance in systems where there are high volumes of fresh air and exhaust air, as well as in climates with long periods of the year where the outdoor air condition is significantly colder or hotter than the required indoor condition, such as regions with very cold winters or with long, hot and humid summers (especially tropical and sub-tropical climates).

 

In particular, the system is often applied in the following applications:

  • Pharmaceutical facilities
  • Electronics
  • Laboratories
  • Animal research facilities

 

Product Options

 

Our run-around coil solutions provide a variety of flexible options that allow us to adapt a solution that meets the performance and investment needs of each project. A selection of the customisation options available include:

 

  • 2-pipe/3-pipe arrangements
  • 1-to-1 systems or many-to-many
  • Optional feed-in heating/cooling on the water-side
  • Cloud monitoring platform
  • Open or cased skid arangement
  • Optional duty/standby pump arrangement
