The design process has been radically optimized, and so has the influence of all geometric parameters within the exchanger.
The software allows to verify an existing PPHE as well as to design it, fixing some of the dimensional parameters in order to obtain a certain capacity.
It is possible to consider the orientation of the exchanger in vertical or horizontal. The checks allow you to set certain parameters such as plate height, plate width, and frame width in a fixed way, so as to keep some values in a fixed mask, keeping others free. If for example, the frame width is left free, setting the distance between one plate and another, the number of plates will be changed. It is possible to leave everything free, the design mode will find the heat exchanger that meets the user’s requirements. The program also allows selecting nozzles on one side and the other, automatically.

For energy recovery applications, the user can also perform an  Energy Recovery Analysis of the heat exchanger, evaluating the annual amount of energy recovered, the payback period and even the amount of CO2 recovered!
This analysis is performed with practicality, considering factors such as cost and weight of the material, commercial factor, energy cost, hours of operation per day, and days of operation per year. This analysis is essential when choosing a Pillow Plate Heat Exchanger for a certain heat recovery application and also to compare its costs with other types of heat exchangers such as Shell and Tubes Heat Exchangers.

In applications like the steam condenser, the user can do all the transformations, so have a superheated gas, which then condenses, and then have a subcooled liquid. A qualitative graph allows the user to identify the desuperheating, condensing, and subcooling parts.

Falling Film Chillers are chillers, whose purpose is to generally cool water or glycol water. On top of the Pillow Plate Bank, there is a water distributor, and the water comes down from it by gravity, spreads out over all the plates then flows by gravity down the walls. So the heat exchange, in this case, is not done by convection, but it is a heat exchange by conduction. This method by conduction becomes very efficient when the film thickness is low. The Falling Film module contains equations to calculate the film thickness as a function of flow rate, size, and distribution. The program calculates the film thickness and, as a function of it, the heat transfer coefficient is calculated. In these cases, the plate distance is very large.
By clicking on Cost/Weight in this case there is no energy saving, as there is no heat recovery, but the calculation mask only provides the cost of the actual product according to the input provided.

In AIR HEATER applications, air needs a fan to move, so by verifying this heat exchanger and clicking on the Cost/Weight button, it is possible to have the so-called LCC Analysis, that is LIFE CYCLE COST ANALYSIS of the product. In the LCC analysis, I can consider fan efficiency (the smaller the fan size, the lower the efficiency), material cost, commercial factor, energy cost, hours of daily operation and days of annual operation, Kg of carbon dioxide per kWh. The software once again will calculate the cost of the product, provide with the annual plant operating hours, make an indicative analysis of the cost, give the absorbed power of the fan and therefore its annual consumption, the energy annual cost, the life cycle cost and the equivalent Kg of CO2 emitted into the atmosphere. While these calculations are indicative, at a glance they allow the user to compare thecost of one product with another, in a matter of seconds.
It is possible to further elaborate the economic calculation according to special needs and rules. For any request, we are available at sales@unilab.eu
