ACDS-HP Air Cooled Scroll Heat Pump

Cooling Capacity from 18 to 40 RT (65 to 140 kW)
Heating Capacity from 20 to 40 RT (70 to 142 kW)

The ACDS-HP features:

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

The Dunham Bush ACDS-HP Series represents a major technological advancement for modern buildings looking to eliminate traditional gas boilers in favor of a clean, all-electric thermal framework. Running separate boilers for hot water and standalone central air conditioners wastes substantial monthly energy. The ACDS-HP solves this by utilizing an advanced thermodynamic cycle that moves ambient heat to provide space cooling, while simultaneously upgrading rejected energy into high-temperature water loops.

The backbone of this performance lies in its use of multiple high-efficiency scroll compressors. The scroll compression profile utilizes smooth, orbiting motion to significantly reduce mechanical friction, lower operating noise levels, and minimize vibration signatures compared to traditional reciprocating systems.

For maximum heat transfer capabilities, the ACDS-HP utilizes Dunham-Bush’s patented flooded shell-and-tube configurations (or optional high-efficiency plate heat exchangers). This design yields exceptionally low approach temperatures and keeps the system’s Coefficient of Performance (COP) remarkably high, even during volatile load conditions. The compact, structural frame features an open-air V-coil condenser profile that utilizes direct-drive propeller fans to vent heat cleanly into the atmosphere without the risk of hot-air recirculation.

Key Technical Highlight Matrix

Core Functions of the Dunham Bush ACDS-HP Series

• Reversible / Simultaneous Cycle Management: Functions flexibly as an air-to-water heat pump system, supplying central chilled water for air conditioning or upgrading thermal energy to provide hot water loops.

• Intelligent Multi-Scroll Compressor Staging: Features multiple compressors that step up and down to match changing real-time facility loads. This eliminates the large current inrush spikes typical of single large industrial motors.

• Built-in Integral Sub-Cooling Loops: Incorporates sub-cooling circuits directly inside the condenser coil matrix. This configuration boosts net cooling tonnage and elevates thermodynamic efficiency without adding stress to the local power supply.

• Lead-Lag Microprocessor Runtime Balancing: The onboard controller automatically tracks and balances compressor run-hours. By alternating the lead compressor during startup sequences, it equalizes wear and extends the system's mechanical lifespan.

Strategic Importance Across Bangladesh

1. Government Institutes, Public Health & Administration Hubs

State assets—such as regional healthcare clinics, municipal administrative centers, and state-owned corporate training complexes—demand high reliability but face strict limitations regarding space and water resources.

• Zero Fresh Water Depletion: Running completely on an air-cooled heat-transfer setup, the ACDS-HP frees public facilities from operating large water delivery lines, chemical treatment setups, or rooftop cooling towers.

• Slashes Fuel Grid Strain: Moving hot water production away from gas combustion over to an electric heat pump layout supports national energy goals and helps combat local domestic gas supply drops.

2. Private Sector Enterprises, RMG Hubs & Food Processors

For private enterprises—such as mid-sized pharmaceutical labs, textile garment offices, food processing lines, and boutique hotels—uncontrolled indoor temperatures or process water drops can hurt overall efficiency.

• Continuous Built-in Redundancy: By using multiple staged scroll compressors across independent circuits, if one loop requires routine sensor or filter servicing, the secondary circuit remains online to keep your business running.

• Tropicalized Weatherproof Body: The exterior casing is constructed from thick, heavy-gauge galvanized steel protected by a baked powder coat finish, keeping sensitive electronic controllers completely insulated against high humidity and monsoon rains.

Frequently Asked Questions (FAQs)

Q1: What are the primary efficiency benefits of an air-cooled scroll heat pump like the ACDS-HP?

Ans: Instead of burning fuel to create heat energy, the ACDS-HP extracts thermal energy from outdoor air and upgrades it to heat your water loop. This process lets the system achieve a high Coefficient of Performance (COP), delivering multiple kilowatts of heating energy for every single kilowatt of electricity drawn from the grid.

Q2: How does the multiple scroll compressor design help lower electricity bills?

Ans: Traditional single-compressor plants must turn completely on or off, creating heavy spikes in electrical demand. The ACDS-HP operates multiple smaller scroll compressors. When facility cooling or heating needs drop, the system powers down unneeded scroll loops, keeping power bills low.

Q3: Does the Dunham Bush ACDS-HP include built-in protection against local power line quality drops?

Ans: Yes. The advanced integrated microprocessor control panel actively monitors incoming electrical phases, under-voltage drops, and current imbalances. If grid power quality sags past safe operational limits, it executes a protective safety shutdown to prevent compressor motor damage.

Q4: Can this heat pump keep working if my building only requires space cooling and zero hot water?

Ans: Absolutely. The intelligent control system is designed for high operational flexibility. It handles full cooling loads during hot summer peaks, full heating during cooler months, or combined operation based on your real-time building requirements.
