Dantherm Selection guide 2/4 - Using the Mollier hx-diagramDantherm
The document discusses using the Mollier hx-diagram to determine dehumidification needs. It explains that the Mollier hx-diagram allows you to determine parameters like enthalpy and dew point by plotting temperature and relative humidity on the chart. An example is provided where 20°C and 60% RH is plotted, then traced to 30°C to determine the enthalpy increase needed is 10 kJ/kg. Another example shows how to use the chart to calculate that lowering a room from 20°C to 0°C at night would cause 0.48 liters of condensation to form. The document encourages using the Mollier hx-diagram and contacting the company for further de
Dantherm Selection Guide 3/4 - Calculation of the dehumidification loadDantherm
This document discusses calculating dehumidification load and selecting the proper dehumidifier. It explains that dehumidification falls into two categories: excess water in air and drying materials. When determining load and selecting a dehumidifier, factors like room size, air changes, meteorological data, and other moisture sources must be considered. A key factor is air changes, as outside air brings in moisture and temperature that impact indoor conditions. A formula is provided to calculate the additional water load from air changes.
The document describes Dantherm's line of Vent packaged fresh air units with heat recovery for applications such as schools, institutions, and gyms. The Vent units come in C and R models, with the C using a cross-flow heat exchanger suitable for industrial use and humid rooms, while the R has a rotating heat wheel providing up to 80% efficiency. Key features include high efficiency fans and motors, filters, insulated cabinets, integrated controls, and accessories such as reheating coils.
The document discusses ventilation systems for swimming pool halls. It describes some common problems with pools like evaporation, humidity, and chlorine levels. It then provides examples of calculating air temperature, relative humidity, and evaporated water for different pool water temperatures. Finally, it discusses different ventilation system solutions like heat pump dehumidifiers and fresh air systems, highlighting the benefits of systems with heat recovery.

Dantherm Selection Guide 4/4 - Where and why is dehumidification needed?Dantherm
This document discusses where and why dehumidification is needed. It explains that dehumidification is often required to preserve goods and materials in storage rooms and warehouses by keeping relative humidity (RH) below a certain level. Proper insulation and air changes are important factors to control humidity. Dehumidification is also necessary to protect equipment and structures at water works from condensation that occurs when the dew point is higher than surface temperatures of pipes and other metal surfaces. High humidity can cause corrosion, mold growth, and other issues. The document provides a table showing maximum recommended RH levels at different temperatures to avoid condensation when water is at 7°C.
The document discusses different conditions for a swimming pool throughout the year using a water-cooled condenser and dehumidification damper from DanX. In the summer, the system maintains indoor conditions of 30°C and 55% humidity while outdoor conditions vary from 30-43°C. In cooling mode, it cools the indoor air to 30°C and 55% when outdoors reaches 32°C. At night, it lowers the indoor temperature to 23°C. In winter, the system heats indoor air to 30°C and 55% humidity even when outdoors drops to -20°C and 100% humidity.
The document summarizes ventilation units from Dantherm A/S including VentR and VentC units. VentR units are suitable for comfort ventilation with up to 80% heat recovery efficiency and small dimensions. VentC units are suitable for industrial ventilation where fresh and exhaust air should not mix, with 55-65% efficiency. The document describes the unit construction, fans/motors, heat exchangers, filters, controls, advantages over other units, and Dantherm's calculation program for unit selection.
