Operating cost analysis: sources and methods

Cooling Tower Energy & Operating Cost Analysis Software

The Cooling Tower Energy & Operating Cost Analysis Software is an in-house program developed by Tower Tech and is used to design and evaluate the performance and life-cycle costs associated with a cooling tower. This version can be used to estimate the cost to purchase and operate a Tower Tech cooling tower and a competitor’s tower. A number of assumptions about the details of the competitor’s ...

Heat Transfer, Environmental Benefits, and Social Cost Analysis of Different Insulation Methods by Considering Insulation Disadvantages

In this paper, the thermal performance of four common insulators in two internal and external insulation systems is investigated for the ASHRAE setpoint range by applying detailed numerical simulation and Anti-Insulation phenomenon. Anti-Insulation phenomenon and consequent extra load on the HVAC system can occur following the thermal insulation of a building if proper temperature setpoint is n...

Evaluation of soil pollution sources using multivariate analysis combined with geostatistical methods in Zanjan Basin, Iran

The increase of heavy metals concentration in soils is potentially threatening the environment and human health. In this paper, multivariate analysis methods such as Positive Matrix Factorization (PMF), Principal Component Analysis (PCA) and Cluster Analysis (CA) combined with geostatistical method were employed to identify the potential sources of soil pollution. A collection of 103 samples we...
