Total Heat Transfer This process involves the transfer of sensible and la-tent heat energy. Latent heat energy is dependent on the amount of water vapor in the air and therefore total heat transfer can only occur when water vapor is trans-ferred from one airstream to the other. In an energy recovery wheel this transfer is accomplished through
energy-recovery efficiency of 60%. Fresh outdoor air for ventilation is delivered through a high-efficiency heat exchanger providing significant energy savings year round by means of a Z-Duct sensible-energy, aluminum heat exchanger. Micro-Zs are very compact, lightweight, and offer an affordable solution to reduce energy and improve indoor air
Effect of the Channel Height of the Enthalpy Exchanger on The largest energy saving was obtained for the enthalpy exchanger having the smallest channel pitch of 1.8 mm. Annual energy saving calculated to gas energy amounted to 49 899 MJ for Seoul area. Both efficiencies and power consumption increased as the channel pitch of enthalpy exchanger decreased.
PCM that enhance the heat transfer between air and PCM. A latent heat thermal energy storage (LHTES) system for Night Ventilation with PCM (NVP) was developed by (Yanbing et al. 2003). In this work at night, the outdoor cool air is blown through the PCM package bed system to charge coldness of air to PCM. During daytime, heat is transferred to

Understanding Energy Recovery in Rotary Heat Exchangers Sep 30, 2019 · This waste heat with high thermal parameters can be used to improve the energy and economic efficiency of enterprises by directly heating air in ventilation systems or by augmenting technological processes requiring higher temperatures (e.g. the heat source for heat pumps used for pasteurization in the food industry, or for the production of electricity in the organic Rankine Cycle or
where q is the total heat-transfer rate (BTU/min), A is the total internal contact area (ft 2), U m is the mean overall coefficient of heat transfer (BTU/min ft 2 º F), defined as (10) and is the logarithmic mean temperature difference (LMTD), given by (11) As shown in
