WCS-HP Scroll Heat Pump

Heating Capacity from 11 to 74 RT (39 to 260 kW)

The WCS-HP features:

• Multiple Scroll Compressors
• Dunham-Bush Patented Shell & Tube Evaporator and Condenser
• High Efficiency and COP
• Microprocessor Based Controller
• Green Refrigerants

The Dunham Bush WCS-HP Series represents a major advancement in compact thermal technology, designed to replace carbon-heavy, gas-fired boilers with clean, electric heat recovery. While conventional facilities face high operating costs by running standalone water heaters and separate central air conditioning systems, the WCS-HP utilizes a water-to-water thermal cycle to capture and repurpose waste heat. It upgrades low-temperature thermal inputs into high-temperature process hot water, lowering overall facility energy consumption.

The framework of this series relies on multiple high-efficiency scroll compressors. The scroll compression profile uses an orbiting spiral interaction that provides smooth, continuous gas flow, exceptionally low mechanical vibration, and quiet operation. Because the internal parts experience minimal friction, the compressor maintains long runtime intervals before requiring maintenance.

To ensure maximum thermodynamic performance, the WCS-HP utilizes Dunham-Bush’s patented shell-and-tube configurations for both the evaporator and condenser vessels. The interior inner-finned copper tubes optimize heat transfer coefficients, helping the system achieve an exceptional Coefficient of Performance (COP). Managed by a high-precision microprocessor controller, the heat pump keeps water temperature loops perfectly stable even through sudden factory load shifts.

Key Technical Highlight Matrix

Core Functions of the Dunham Bush WCS-HP Series

• Intelligent Multi-Compressor Staging: Matches changing building loads smoothly by cycling individual scroll compressors on and off. This avoids the power spikes caused by single large industrial motors.

• Dual-Purpose Water Loop Management: Functions as a water-to-water heat pump, extracting heat from an available water source (like ground well water or industrial cooling lines) and transferring it to a process hot water system.

• Patented Removable-Head Shell & Tube Fluid Dynamics: Designed with removable water heads that allow maintenance crews to mechanically brush out the copper tubes. This easily removes mineral scale left behind by regional hard water.

• Automated Run-Time Balancing: The microprocessor controller tracks individual compressor run-hours and automatically rotates the starting sequence. This equalizes wear and tear to maximize the overall lifetime of the heat pump plant.

Strategic Importance Across Bangladesh

1. Government Institutes, Public Health & Testing Centers

Public installations—such as specialized government medical clinics, research laboratories, and administrative training academies—require reliable hot water for sanitation, kitchens, and laundry alongside basic space cooling.

• Conserves National Fuel Reserves: By switching thermal hot water generation from natural gas lines to electric heat pumps, the WCS-HP helps ease supply strain on domestic natural gas grids.

• Low Acoustic Signatures: The quiet, balanced operation of the scroll compressors prevents structural sound transmission, allowing installation in rooftop or basement slots directly beneath hospital wards or offices.

2. Private Enterprise, Pharma Facilities & Green Factories

For competitive industrial sectors—such as cleanroom pharmaceutical compounding, food processing, textile finishing, and high-rise commercial spaces—thermal reliability is critical to maintaining daily productivity.

• Insulation Against Gas Volatility: Shifting to an all-electric, high-efficiency heat pump helps factories maintain consistent process temperatures even during local gas pressure drops.

• Meets International Green Standards: The use of green refrigerants with zero Ozone Depletion Potential (ODP), combined with high COP values, helps export-oriented factories qualify for international LEED certifications.

Frequently Asked Questions (FAQs)

Q1: How does a water-to-water scroll heat pump generate hot water efficiently?

Ans: Instead of burning fuel to create heat, the WCS-HP uses a vapor compression cycle to extract thermal energy from an entering water stream and pump it into a separate hot water loop. This allows the system to deliver multiple kilowatts of heating energy for every single kilowatt of electricity consumed.

Q2: What are the main mechanical advantages of scroll compressors over larger screw compressors?

Ans: Scroll compressors are ideal for low-to-medium tonnage applications (11 to 74 RT). They feature very few moving parts, run with minimal vibration, and offer highly reliable part-load performance through step-controlled compressor staging.

Q3: Is this system protected against voltage fluctuations from the local electrical grid?

Ans: Yes. The microprocessor-based controller works alongside safety relays to monitor phase alignment, phase loss, and sudden under-voltage drops. If power quality sags past safe limits, the system triggers a protective shutdown to keep the compressor motors from burning out.

Q4: How do we clean the heat exchangers if our groundwater has a high iron or mineral content?

Ans: The WCS-HP utilizes Dunham-Bush’s patented shell-and-tube heat exchangers built with fully removable water heads. Your maintenance crew can simply unbolt the heads and mechanically brush the inside of the copper tubes to clear scaling and maintain peak heat transfer efficiency.
