Basic Introduction of dehumidifier capacity
Dehumidifier capacity is an important factor when you choose a dehumidifier. This article will introduce it from definition, calculation, and types.
What is dehumidifier capacity
The dehumidifier capacity typically refers to its dehumidification capacity, often measured in liters per day or liters per hour. This value indicates how much moisture the dehumidifier can extract from the air within a specific timeframe, such as a day or an hour. A higher dehumidifier capacity means it can remove moisture from the air more quickly.
Dehumidifier capacity calculation
Dehumidifier capacity is influenced by four primary factors: Present Temperature (°C), Present Humidity Level (% RH), Desired Humidity (% RH), and venue volume. While there’s no exact formula, we can estimate using these methods:
1. Empirical Estimates
Small switchgear/small space: 5-10 liters/day
Medium switch cabinet/medium space: 10-20 liters/day
Large switchgear: 20+ liters/day
2. Calculation Formula
Formula: W = V × ρ × (X2 – X1) ÷ 1000 × 1.2
W: Required dehumidification capacity (kg/h)
ρ: Air density (kg/m³), typically 1.2
V: Venue volume (m³)
X2: Air humidity before dehumidification (kg/kg dry air)
X1: Air humidity after dehumidification (kg/kg dry air)
1000: Unit conversion factor
1.2: Safety factor
Note: This formula provides a general estimate. Actual requirements may vary based on specific conditions and desired performance. Or you can consult the dehumidifier manufacturer.
3. Take a switchgear dehumidifier capacity calculation as an example
Assume that the size of a switchgear is:
Length: 2 meters
Width: 1.5 meters
Height: 2 meters
Internal effective volume: 5.4 cubic meters
Total heat output of the equipment: 1000 watts
Ambient temperature: 25℃
Ambient humidity: 70%
Target humidity: 50%
Simplified calculation:
Assume that 0.2 liters/day of dehumidification is required per cubic meter of space (this value can be adjusted according to actual conditions).
Dehumidifier capacity = 5.4 cubic meters * 0.2 liters/cubic meter/day ≈ 1.08 liters/day
Therefore, you can choose an electrical cabinet dehumidifier with a dehumidification capacity of 1-2 liters/day.
Dehumidifier Types - A dehumidification Capacity-Based Guide
According to the dehumidifier capacity Ranges, the dehumidifier can be divided into small dehumidifiers for small rooms or cabinets, medium dehumidifiers for basements, and Large dehumidifiers for garages and commercial spaces. Here we will introduce the Blue Jay electrical cabinet dehumidifier types from capacity.
High-capacity dehumidifier for Electrical Panel
High-capacity dehumidifiers (600mL/day and above) are designed for larger electrical cabinet applications. These powerful dehumidifiers are ideal for combating high humidity levels in challenging large space cabinets.
Medium capacity dehumidifier
Medium-capacity dehumidifiers (250-350mL/day) are suitable for most small and medium-sized distribution cabinets, control cabinets, instrument cabinets, etc.
Small capacity dehumidifier
A small-capacity electrical cabinet dehumidifier ((100mL/day)) is a compact device designed to remove moisture from small electrical enclosures. It works by condensing the humidity in the air, preventing equipment damage from moisture.
A dehumidifier with a capacity of 100mL/day can effectively remove 100 milliliters of moisture per day. This is often sufficient for small, closed cabinets with minimal heat generation.
It is suitable for small control cabinets, small instrument cabinets, and small distribution cabinets.
Electrical cabinets of different sizes require electrical cabinet dehumidifiers of different capacities. When choosing, you need to consider dehumidification capacity, power consumption, size, and other factors according to the specific situation of the cabinet.
Tips: When choosing and using an electrical cabinet dehumidifier, it is recommended to consult our professionals to ensure that the most suitable product is selected.
