Information
Modern plate heat exchangers can recover the vast majority of sensible energy. Plate heat exchangers are used in a range of commercial, industrial and residential settings. By extracting sensible energy from exhaust air, and using it to cool or heat incoming air, a plate heat exchanger can make a dramatic difference to a building’s energy costs and environmental impact.
As the world battles a pandemic and becomes increasingly focused on securing substantial and clean indoor ventilation, the impact of removing cross-contamination worries cannot be understated. Plate heat exchangers also offer other considerable benefits. Because a plate heat exchanger keeps incoming and exhaust air supplies separate, there is no risk of cross-contamination. 
Calculating the efficiency of plate heat exchangers
Two main models exist to help you calculate the performance efficiency of a plate heat exchanger. The log-mean temperature difference method (LMTD) provides a rate of heat transfer through the following calculation:
Q = UA(FΔTlm)
In this equation, U is the overall heat transfer coefficient, A is the total area of heat transfer, ΔTlm is the log-mean temperature difference, and F is the log-mean temperature difference correction factor. The LMTD approach is most commonly adopted when the inlet and exit temperatures are established, but the size of the heat exchanger is still to be decided. As an alternative to the LMTD approach, the thermal effectiveness method determines the real-world heat transfer occurring inside the heat exchanger against the maximum possible heat transfer. It is expressed as a ratio.
E = Q / Qmax 
This approach is most common when building managers or engineers are attempting to determine the heat transfer rate and the fluid exit temperatures, and already know the size of the heat exchanger and the inlet temperatures. 
Choosing the most efficient plate heat exchanger will depend on your use case and the wider environment in which you operate. By offering reversible energy recovery, counterflow heat exchangers are suitable for both building cooling or heating. Interested to learn more?
