- COOLING: Cleaner, Maintenance-Friendly. Babcock, Glenn A. // Process Cooling & Equipment;Jul/Aug2006, p15
The article discusses four facets of the advanced coil technology in evaporative condensers and closed-circuit cooling towers that contribute to reduced scale formation and fouling tendency. First, the air and water flow in a parallel path. Second, water flow over the coil is increased. Third,...
- Effect of face velocity during refrigeration on hot-gas coil-defrosting near-saturated conditions. Mago, P.J.; Sherif, S.A. // Proceedings of the Institution of Mechanical Engineers -- Part C;Dec2004, Vol. 218 Issue 12, p1507
The heat input required to defrost coils within refrigerated spaces is partially removed with the melt, partially warms the coil and refrigerant and partially escapes to the refrigerated space as sensible heat by convection and radiation and as latent heat by evaporation and sublimation. The...
- Implications of Coil Frosting on System Designs for Low-Temperature Applications. Cleland, Donald J. // ASHRAE Transactions;2005, Vol. 111 Issue 1, p336
Air relative humidity (RH) in a refrigerated facility is determined by the balance between moisture entry (principally through doors) and moisture removal (principally as frost on the air-cooling coil). It has been shown that coil frosting is "unfavorable," leading to very rapid decline in...
