Product Specifications

Technical details and manufacturing context for Dehumidifier

Definition
A mechanical component within a conditioning system that extracts water vapor from air to control humidity levels, typically using refrigeration, desiccant, or other moisture-removal technologies to maintain optimal environmental conditions.
Working Principle
Most commonly operates on refrigeration principle where moist air passes over cold evaporator coils, causing moisture to condense and collect, then dry air is reheated and returned to the environment. Alternative methods include desiccant wheels that absorb moisture or thermoelectric cooling.
Common Materials
Aluminum, Copper, Plastic, Steel
Technical Parameters
  • Moisture removal capacity at standard conditions (30°C, 80% RH) (L/day) Per Request
Components / BOM
  • Compressor
    Compresses refrigerant gas to increase pressure and temperature
    Material: Steel, Copper
  • Evaporator Coil
    Cools incoming air to condense moisture
    Material: Copper, Aluminum
  • Condenser Coil
    Reheats dried air before returning to environment
    Material: Copper, Aluminum
  • Fan
    Circulates air through the dehumidifier
    Material: Plastic, Aluminum
  • Water Collection Tank
    Collects condensed moisture for disposal
    Material: Plastic
Engineering Reasoning
0.5-1.5 MPa (5-15 bar) at 20-40°C inlet air temperature, 30-90% relative humidity input, 10-40% relative humidity output
Compressor discharge pressure exceeding 2.1 MPa (21 bar) or refrigerant temperature surpassing 120°C at condenser outlet
Design Rationale: Refrigerant phase change hysteresis failure due to excessive latent heat load beyond 2500 kJ/kg refrigerant capacity, causing liquid slugging in compressor
Risk Mitigation (FMEA)
Trigger Refrigerant charge loss below 80% of specified 1.2 kg R-134a mass
Mode: Evaporator coil frost accumulation exceeding 5 mm thickness, reducing heat transfer coefficient below 15 W/m²·K
Strategy: Hermetic compressor welding with 0.1 mm maximum leak rate, dual-pressure transducers at 0-2.5 MPa range with 0.01 MPa resolution
Trigger Desiccant rotor degradation below 70% silica gel adsorption capacity
Mode: Moisture removal efficiency dropping below 30% of rated 2.5 L/hour at 25°C, 60% RH
Strategy: Regeneration heater PID control maintaining 150±5°C for 20 minutes per cycle, humidity sensors with ±2% RH accuracy

Frequently Asked Questions

How does this dehumidifier protect machinery and equipment in manufacturing environments?

By removing excess moisture from the air, this dehumidifier prevents corrosion, mold growth, and condensation on sensitive machinery components, extending equipment lifespan and maintaining optimal operating conditions in manufacturing facilities.

What maintenance is required for the compressor and coil components?

Regular cleaning of evaporator and condenser coils, checking refrigerant levels, and ensuring proper airflow around the compressor are essential. The aluminum and copper construction requires periodic inspection for corrosion, with professional servicing recommended annually for optimal performance.
