Total Heat Recovery Heat and Moisture Recovery from Ventilation Air

Total Heat Recovery Heat and Moisture Recovery from Ventilation Air ,Energy and environment are two hot topics world wide today. Energy has been described as “that which makes things go.” It is seen clearly in the transfer of heat and work inside environmental systems. Heat occurs due to a temperature difference between the system and its surroundings, while work makes use of that difference to perform a function. The depleting nature of primary energy resources, negative environmental impact of fossil fuels and low exergetic efficiencies obtained in conventional space heating and cooling are the main incentives for developing alternative heating, ventilating and air-conditioning (HVAC) techniques which can either save energy or employ low-grade thermal energy sources. Today, air conditioning has accounted for 1/3 of the total energy use by the whole society. The percentages are still rising in the fast developing economies like China.

The design of HVAC systems for thermal comfort requires increasing attention, especially in light of recent regulations and standardization on ventilation, so that an optimal level of indoor humidity may be reached and maintained to ensure a comfortable and healthy environment and to avoid condensation damage to the building envelope and furnishings. Fresh air ventilation is necessary, not only for breathing purposes, but also for the prevention of deadly epidemic diseases like bird flu and SARs.
