rotary heat exchangeralso called an energy wheel, or energy recovery wheeland the benefits of incorporat-ing such a device in an air handling unit. PRINCIPLES OF ENERGY RECOVERY Energy recovery involves a transfer of energy between an exhaust airstream and a supply airstream. Figure 1 illustrates the heat transfer process of an energy recov-
HOLTOP heat recovery wheel working principle Rotary heat exchanger (wheel) is mainly used in building ventilation or in the air supply/discharge system of air conditioning equipment. The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor.
Designing HVAC system with and without heat recovery Heat Recovery Wheel comes under rotary air to air heat ex-changer, which consist of wheel of alluminium substrate coat-ed with desiccant which reduces the cross contaminations to minimum. The wheel comes with segmented or unsegmented options, helping easy for maintenance. The airflow across the wheel is laminar due to coating of desiccant. The wheel comes with the diameters in between
Aug 20, 2020 · The below figures shows the details of heat Recovery Wheel for both AHU & FAHU in cross sectional view. Fig.2 FAHU with Heat Recovery wheel Fig.3 AHU with Heat Recovery wheel. To simplify the understanding, the working process is explained in points as follows, In general terms it is a type of energy recovery heat exchanger between two streams

Rotary Heat Exchanger(heat Recovery Wheel) - Buy Rotary Holtop total heat type heat/energy recovery wheels(rotary heat exchangers) can be widely installed into the air handling units and ducts for heat/energy recovery and air ventilation.
The storage mass of a rotary heat exchanger. The aluminum foil is between 0,07 and 0,1 mm thick while the waves can be between 1.4 and 2.5 millimeters high. The thickness and height of the wave shapes used varies depending on the dust and contamination level
Rotary Wheel Heat Recovery - ppss.thRotary heat exchanger is composed of alveolate heat wheel, case, drive system and sealing parts. The exhaust and outdoor air pass through half of the wheel separately, when the wheel rotates, the heat and moisture are exchanged between the exhaust and outdoor air. The energy recovery efficiency is up to 70% to 90%. Entering the cold air half
A Heat Recovery Wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, or Thermal (Heat) wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of an air-handling system or in the exhaust gases of an industrial process, in order to recover the heat energy.
