Plate Heat Exchanger Unit
What is a Plate Heat Exchanger Unit?
A Plate Heat Exchanger Unit is an integrated thermal exchange system that combines a plate heat exchanger (PHE) with auxiliary equipment (e.g., pumps, valves, control systems) to achieve efficient and controlled heat transfer between fluids. Below is a detailed breakdown of its key aspects:
Selection tip：Best Used When:
Core Components
A typical plate heat exchanger unit consists of the following key components:
Working Principle
A[Hot Fluid Inlet] --> B[Plate Heat Exchanger] --> C[Hot Fluid Outlet]
D[Cold Fluid Inlet] --> B --> E[Cold Fluid Outlet]
F[Control System] -->|Adjusts| G[Pump/Valves]
Hot and cold fluids flow counter-currently/cross-currently through thin plates for rapid heat transfer.
Automatically adjusts pump speed or valve opening (e.g., maintains freshwater outlet temperature within ±1°C).
Unit vs. Standalone Heat Exchanger
Case Study of Plate Heat Exchanger Unit: Domestic Hot Water System
(Example applications in hotels/hospitals/residential communities)
System Components and Functions
Operational Process
A[Heat Source (Steam/Boiler Water 80-90°C)] --> B[PHE Primary Side]
C[Cold Water Inlet (10-15°C)] --> B --> D[Domestic Hot Water (55-60°C)]
D --> E[Storage Tank (Optional)] --> F[Usage Points]
G[Control System] -->|Adjusts| H[Steam Valve/Pump]
Key Parameters:
Hot water output: 1m³/h (supports 50 continuous showers)
Heat transfer efficiency: ≥90% (approach temp. 3-5°C)
Working pressure: ≤1.0MPa (compliant with GB 50015)
Typical Application Scenarios
Case 1: Luxury Hotel Hot Water System
24/7 stable 60°C supply, peak demand 20m³/h
2 parallel PHE units (1+1 backup), single unit capacity 1.2MW
Titanium plates (corrosion-resistant, Cl⁻ tolerance ≥500ppm)
Smart variable speed: 40% energy saving in low-flow nighttime mode
Case 2: Hospital Operating Room Hot Water
Sterile, constant temperature, sub-second response
Dual PHE units + storage tank (99.9% availability)
80°C periodic sterilization (auto-triggered weekly)
Comparison with Traditional Systems
Conclusion: With advantages in efficiency, energy savings, and smart operation, plate heat exchanger hot water units are progressively replacing traditional systems as the preferred solution for residential and commercial applications.
