Dehumidification >> How To Dehumidify A Water Damaged House

Dehumidification with Climate Changer™ Air Handlers Triple the amount of water removed The Trane ™ desiccant dehumidification system is How To Dehumidify A Water Damaged House an award winning method for controlling space humidity. A desiccant wheel is configured in series with the cooling coil to significantly improve the coils ability to remove water. 

When operating, the wheel transfers water vapor from downstream of the cooling coil to How To Dehumidify A Water Damaged House the air upstream of the coil. The cooling coil gets a "second shot” at dehumidifying the air. Adding to a Trane air handler can double and even triple the amount of water removed. breaks the dewpoint barrier! is more then just a better dehumidifier. breaks the dew point barrier! With a standard unit, dewpoint is 3 to 8 degrees lower than a coil-only unit. An enhanced unit can have a dewpoint up to 20 degrees drier.

 Enhanced uses a preheat coil to dry the air even more for space humidity control in very critical applications like operating rooms, labs and museums. Humidity control can be active 24/7, at full and part-load. Trane controls, How To Dehumidify A Water Damaged House now a part of every unit, can use one percent, two percent, and three percent precision humidity sensors as a single unit solution for controlling humidity, temperature and ventilation. Trane Custom Climate Changer™ air handlers with systems can have onboard DX or chilled water chillers, giving building owners turnkey system flexibility. 

The overall unit performance is so outstanding that Frost and Sullivan ranked the Trane desiccant dehumidification system as the best new HVAC dehumidification product for 2006. The unit is a mixed-air, 100- percent return air, or How To Dehumidify A Water Damaged House 100-percent dedicated outdoor air unit. Mixed air goes through an optional preheat coil, wheel, supply fan, cooling coil, optional reheat coil, optional final filters. A system in a Custom Climate Changer™ air handler can have attached condensing units, chillers and water piping packages. 

All units have Trane unit controls and temperature/humidity sensors designed for the application. A Traq™ outside airflow monitoring sensor and a fan inlet airflow measuring system with a piezometer ring are How To Dehumidify A Water Damaged House optional. Size range is 1,000 - 70,000 cfm. Note: Under LEED, this unit may qualify for innovation points. Trane air handlers can include both a dehumidification wheel and an energy recovery wheel for thermal savings. These units are 100-percent dedicated outdoor air units or mixed-air units. All units have Trane controls and sensors. Size range: 1,000 to 70,000 cfm. Note: Under LEED, this unit may qualify for innovation points. 

Dry Storage/Archives. This space type has a small latent load in the space and requires very little ventilation air to be introduced. The challenge for humidity control is How To Dehumidify A Water Damaged House keeping the space humidity at the desired low level. Since the mixed-air relative humidity is low, the desiccant wheel will be operating at its most efficient conditions to help lower the supply-air dew point. This will raise the required coil temperature and also lower the need for reheat.

 Hospital Operating Rooms. Operating rooms should be at a low relative humidity (35-55 percent RH) and cool (60°- 68° F). This is an excellent application for How To Dehumidify A Water Damaged House . The improved latent capacity not only reduces the required cooling needed but the supply-air dew points can eliminate the need for a secondary refrigeration coil or a heat-regenerated active desiccant system. Because active desiccant systems provide hot air (which would then require a significant amount of post-cooling), using a system can result in significant energy savings. 

Laboratories. A system can help achieve the lower relative humidity needed for How To Dehumidify A Water Damaged House laboratories. Because the exhaust air often contains contaminants, total energy (enthalpy) recovery from the exhaust air is usually not permissible. A system can improve energy efficiency and latent removal from the space without the need for exhaust air stream. 

Schools and Colleges. Space latent load in classrooms can be high year round due to the high occupancy levels, resulting in a lower SHR at part load conditions. A air handler can help achieve the higher latent capacity needed in How To Dehumidify A Water Damaged House classrooms. The system can be either constant volume or variable air volume (VAV). Humidity levels in schools can elevate times when the buildings are unoccupied. The same air handler can be used as a recirculating dehumidifier to keep the humidity levels under control during unoccupied hours.

 Retail Stores and Restaurants. Using a air handler with a DX system can How To Dehumidify A Water Damaged House provide better part-load dehumidification without requiring as much cooling or reheat energy as a cool-reheat system. 

Office Buildings. A constant volume or VAV system can be enhanced to get better humidity control in the space. A system can also be helpful in How To Dehumidify A Water Damaged House offices designed with under-floor air distribution. Air delivered at floor level is at a warmer dry-bulb temperature (typically around 65°F). This can create a dehumidification challenge in many climates. A system can deliver air at 65°F dry-bulb temperature, and at a dew point of 55°F to 58°F, without the need for overcooling and reheat (or mixing in bypassed return air). 

The system can be applied in applications that require active humidity control. system benefits over cool-reheat units varies, but, in general, How To Dehumidify A Water Damaged House you can expect: Higher latent capacity per ton of total capacity, Lower achievable supply-air dew point, and Reduced reheat energy Quieter operation Very low controlled humidity spaces. In the very low 35 to 45 percent relative humidity applications, the air handler supplyair dew point needs to be in the 25° F to 40° F dewpoint range.

 Enhanced units can achieve these levels without using complex and expensive gas heat regenerated desiccant wheels, glycol chillers or How To Dehumidify A Water Damaged House refrigeration defrost DX systems. Low controlled humidity spaces. In the 55 to 60 percent relative humidity spaces, the space dewpoint will be in the 40 - 57 dewpoint range. A unit, with it’s increased latent capacity and lower SHR (Sensible Heat Ratio), can match sensible and latent output to the space at full and part load. The result: Tighter humidity control with less energy and noise.
