Air Mixture: Calculating the resulting state when two air streams meet.

Heating & Cooling: Sizing coils for sensible or latent heat changes.

Adiabatic Cooling: Calculating the state of air after water evaporation (evaporative cooling).

Specialty Modules: Includes specific thermal calculation tools for swimming pools (heat loss and humidity control) and industrial processes like odor treatment or misting systems for greenhouses. 2. User Interface & Workflow

PsychroSI operates through a custom toolbar within Microsoft Excel.

Toolbar Navigation: Access procedures, calculation boxes, and macros via a personalized command bar.

Sheet Management: Worksheets are created separately to keep file sizes light. Users can duplicate sheets for similar studies to quickly modify parameters for comparison.

Weather Data Library: The program includes an integrated library of climatic data used for dimensioning air-conditioning installations. 3. Step-by-Step Calculation Guide

Select Units: Ensure the program is set to International System (SI) units (as indicated by the "SI" in the name).

Define Initial State: Input your known values (e.g., outside air at 35°C DBT and 40% RH) into the calculation box. Perform Process Calculation:

For Heating/Cooling, enter the target temperature or desired heat output.

For Air Mixing, input the flow rates and properties of the two air streams to find the "Mix" state.

Analyze Results: The program will output the specific volume, humidity ratio ( ), and enthalpy ( ) required for equipment sizing. 4. Application Examples

4. Why This Is Valuable for ThermExcel Users

No more guessing: Engineers can visually see how latent vs sensible loads affect humidity.
Prevents design errors: Stops undersized coils (which cause high RH) or oversized coils (which cause fogging).
Mold litigation prevention: The condensation map provides a hard number: “At design conditions, this wall will condense.”

The Cold Logic: Simulating "Psychrosi" with the ThermExcel Programme

By: [Your Name]

When you hear the word "psychrosi" (ψύχρωση), you might think it’s a new medical condition or a character from a fantasy novel. In reality, it’s a fascinating Greek term that simply means cooling, chilling, or the process of becoming cold.

But in the world of thermal engineering, cooling isn't simple. It’s a battle against physics. And when you need to win that battle for a building, an industrial pipe, or a heat exchanger, one tool stands out for the old guard of European engineers: ThermExcel.

Here is why the marriage of this legacy software and the concept of psychrosi still matters in a world of CFD and BIM.

3.2 Thermexcel’s Modeling Approach

Thermexcel solves the following for each coil row and segment:

Sensible heat transfer: Q_sens = m_dot_air * cp_air * (T_air_in - T_air_out)
Latent heat transfer: Q_lat = m_dot_air * h_fg * (W_in - W_out)
Total heat: Q_total = m_dot_air * (h_in - h_out)

The software uses the ε-NTU method extended to dehumidifying coils, with correlations for:

Colburn j-factor for heat transfer
Friction factor f for pressure drop
Mass transfer analog (Chilton-Colburn analogy)

Step 2: Defining Initial Air Conditions (State 1)

Assume we have outside or return air at:

Dry-bulb temperature (T_db1): 35°C (95°F)
Relative humidity (RH1): 60%

In ThermExcel, use the following functions in cells:

Humidity Ratio (W1): =Psychro("W", T_db1, RH1, 1) → Returns kg/kg of dry air.
Enthalpy (h1): =Psychro("h", T_db1, RH1, 1) → Returns kJ/kg.
Dew Point (T_dp1): =TDew(T_db1, RH1)

Conclusion

The Thermexcel Psychrosi program bridges the gap between the old-school psychrometric chart and modern digital speed. It retains the accuracy required for professional engineering certification while utilizing the flexibility of Excel.

For any HVAC engineer looking to streamline their workflow and eliminate calculation errors, integrating the Psychrosi module into your toolkit is a smart move. It turns a complex thermodynamic puzzle into a simple, data-driven solution.

The ThermExcel PsychroSI program is a specialized calculation tool designed for Excel that focuses on the psychrometric properties of humid air. In the professional world of HVAC engineering, it acts as a digital "brain" for sizing and optimizing air treatment systems.

Here is a short story centered on this specialized software. The Architect of Air

In the high-pressure world of industrial HVAC design, Julian was known for his precision. His current project was a massive aquatic center, a "glass bubble" where the humidity levels could easily turn a pleasant swim into a suffocating sauna. To solve it, Julian didn’t just need a calculator; he needed a master of thermodynamic states. He opened his trusty ThermExcel toolkit and launched PsychroSI.

The interface was familiar—a rational layout of Excel tables powered by Visual Basic for Applications (VBA). For Julian, the beauty of PsychroSI lay in its flexibility. He entered the indoor design conditions: dry-bulb temperature and relative humidity. Instantly, the program’s internal macros calculated the specific humidity, enthalpy, and dew point.

"Let’s see what happens when the outside winter air hits the glass," Julian muttered. Using the program's specific procedures for air mixture and reheating, he began simulating the thermal shock. PsychroSI allowed him to duplicate his calculation sheets effortlessly, testing "what-if" scenarios for heat recovery and cooling coils without losing his original data.

As he adjusted the airflows, the program automatically updated the entire assessment. He could see exactly how much energy would be spent on reheating the dehumidified air to keep the pool deck comfortable. By the time he reached the synthesis stage, Julian had a complete, currency-converted cost breakdown for the client, all exported directly from his Excel-based sizing tools.

The project was approved within the week. For the guests at the aquatic center, the air felt perfectly crisp and clear. They didn't see the complex VBA code or the psychrometric tables—they just felt the invisible hand of a perfectly programmed environment.

The ThermExcel PsychroSI programme is a specialized Excel-based software tool designed for HVAC engineers, researchers, and building designers to perform precise psychrometric calculations. The name "PsychroSI" is derived from psychrometrics (the study of moist air properties) and SI (International System of Units), though the software is often available in versions supporting US units as well. Core Functionality of PsychroSI

The primary utility of the PsychroSI programme is its ability to determine the complete state of humid air based on just two input parameters. By entering any two known variables, the software uses iterative algorithms to calculate all other related thermodynamic properties. Common input pairs include:

Dry Temperature combined with Relative Humidity, Wet Bulb Temperature, Specific Moisture, or Enthalpy. Relative Humidity and Specific Moisture. Specific Moisture and Enthalpy.

The programme maintains a high degree of precision, typically with a margin of error of no more than 0.1°C for temperature calculations. Key Modules and Advanced Calculations

Beyond basic point-state calculations, the PsychroSI suite includes specialized modules for complex HVAC processes:

Air Mixture and Heat Exchange: The software can calculate the resulting state of air when two different streams are mixed, or when air is subjected to reheating or cooling.

Adiabatic Processes: It models cooling through water spraying (evaporative cooling), where the air reaches saturation without external heat exchange.
